usethis (development version)

  • git_vaccinate(), edit_git_ignore(), and git_sitrep() are more careful to consult, reveal, and set the core.excludesFile in user's Git configuration (#1461).

  • use_github_action_*() functions have been updated in response to the pak-based workflows becoming the standard workflows in r-lib/actions.

  • use_github_pages() and use_pkgdown_github_pages() use a new method for creating an empty, orphan gh-pages branch. This is necessary due to new GitHub behaviour, where it has become essentially impossible to refer to the empty tree (#1472).

  • "usethis.overwrite" is a new option. When set to TRUE, usethis overwrites an existing file without asking for user confirmation if the file is inside a Git repo. The normal Git workflow makes it easy to see and selectively accept/discard any proposed changes. This behaviour is strictly opt-in (#1424).

  • use_lifecycle() now imports lifecycle::deprecated() (#1419).

  • use_code_of_conduct() now requires a contact argument to supply contact details for reporting CoC violations (#1269).

  • We no longer suggest including your test environments in cran-comments.md, since there's no evidence that CRAN finds it useful, and it's annoying to keep up to date (#1365).

  • use_tidy_release_test_env() has been deleted since we no longer recommend including test environment in CRAN comments (#1365).

  • Added use_import_from() to put @importFrom pkg fun into a package in a consistent way (@malcolmbarrett, #1377)

  • DESCRIPTION files generated by usethis no longer include LazyData by default per new CRAN checks; instead, LazyData is now added the first time you use use_data() (@malcolmbarrett, #1404)

  • Functions that provide code to load packages in your .Rprofile now use rlang::check_installed() to make sure the package is installed locally (@malcolmbarrett, #1398)

  • use_package() no longer guides the user on how to use a dependency when no change was made (@malcolmbarrett, #1384)

  • The minimum version of gh has been bumped to help more people upgrade to the gh version that supports current GitHub PAT formats (#1454 @ijlyttle).

usethis 2.0.1

  • All functions that require a package now ask you if you'd like to install it.

  • Added edit_template() for opening and creating files in inst/templates (for use with use_template()) (@malcolmbarrett, #1319).

  • use_article() now creates the file in the vignettes/articles/ (#548).

  • use_lifecycle() has been updated for changes in our lifecycle workflow (#1323).

  • use_tidy_pkgdown() has been renamed to use_pkgdown_github_pages() since the function is useful for anyone who wants to automatically publish to GitHub pages, not just the tidyverse team (#1308).

  • use_release_issue() includes a bunch of minor improvements. Most importantly, for initial CRAN release we now include a number of common things that CRAN checks for that aren't in R CMD check.

  • use_readme_rmd(), use_readme_md(), use_tidy_contributing(), and use_tidy_support() use updated logic for determining the OWNER/REPO spec of the target repo (#1312).

usethis 2.0.0

Adoption of gert and changes to Git/GitHub credential handling

Usethis has various functions that help with Git-related tasks, which break down into two categories:

  1. Git tasks, such as clone, push, and pull. These are things you could do with command line Git.
  2. GitHub tasks, such as fork, release, and open an issue or pull request. These are things you could do in the browser or with the GitHub API.

We've switched from git2r to the gert package for Git operations (https://docs.ropensci.org/gert/). We continue to use the gh package for GitHub API work (https://gh.r-lib.org).

The big news in this area is that these lower-level dependencies are getting better at finding Git credentials, finding the same credentials as command line Git (and, therefore, the same as RStudio), and finding the same credentials as each other. This allows usethis to shed some of the workarounds we have needed in the past, to serve as a remedial "credential valet".

Under the hood, both gert and gh are now consulting your local Git credential store, when they need credentials. At the time of writing, they are using two different even-lower-level packages to do this:

Even now, gert and gh should discover the same credentials, at least for github.com. In the future, these two packages may merge into one.

Git/GitHub credential management is covered in a new article:
Managing Git(Hub) Credentials

The main user-facing changes in usethis are:

  • usethis should discover and use the same credentials as command line Git.
  • usethis should be able to work with any GitHub deployment. While github.com is the default, GitHub Enterprise deployments are fully supported. The target GitHub host is determined from the current project's configured GitHub remotes, whenever possible.

As a result, several functions are deprecated and several other functions have some deprecated arguments.

  • Deprecated functions:
    • use_git_credentials()
    • git_credentials()
    • github_token()
  • Functions with (deprecated arguments):
    • create_from_github() (auth_token, credentials)
    • use_github() (auth_token, credentials)
    • use_github_links() (host, auth_token)
    • use_github_labels() (repo_spec, host, auth_token)
    • use_tidy_labels() (repo_spec, host, auth_token)
    • use_github_release() (host, auth_token)

The switch to gert + credentials should eliminate most credential-finding fiascos. Gert also takes a different approach to wrapping libgit2, the underlying C library that does Git operations. The result is more consistent support for SSH and TLS, across all operating systems, without requiring special effort at install time. More users should enjoy Git remote operations that "just work", for both SSH and HTTPS remotes. There should be fewer "unsupported protocol" errors.

GitHub remote configuration

Usethis gains a more formal framework for characterizing a GitHub remote configuration. We look at:

  • Which GitHub repositories origin and upstream point to
  • Whether you can push to them
  • How they relate to each other, e.g. fork-parent relationship

This is an internal matter, but users will notice that usethis is more clear about which configurations are supported by various functions and which are not. The most common configurations are reviewed in a section of Happy Git.

When working in a fork, there is sometimes a question whether to target the fork or its parent repository. For example, use_github_links() adds GitHub links to the URL and BugReports fields of DESCRIPTION. If someone calls use_github_links() when working in a fork, they probably want those links to refer to the parent or source repo, not to their fork, because the user is probably preparing a pull request. Usethis should now have better default behaviour in these situations and, in some cases, will present an interactive choice.

Default branch

There is increasing interest in making the name of a repo's default branch configurable. Specifically, main is emerging as a popular alternative to master. Usethis now discovers the current repo's default branch and uses that everywhere that, previously, we had hard-wired master.

git_branch_default() is a newly exported function that is also what's used internally.

use_course(), use_zip(), and create_download_url() all have some support for forming the URL to download a .zip archive of a repo, based on a repo specification (e.g. OWNER/REPO) or a browser URL. These helpers now form a URL that targets HEAD of the repo, i.e. the default branch.

Changes to Git/GitHub functionality

The default Git protocol is now "https" and we no longer provide an interactive choice, by default, in interactive sessions. As always, a user can express a preference for "ssh" in individual function calls, for an R session via use_git_protocol(), and for all R sessions via the usethis.protocol option (#1262).

pr_resume() is a new function for resuming work on an existing local PR branch. It can be called argument-less, to select a branch interactively.

pr_fetch() can also be called with no arguments, to select a PR interactively. The owner argument is replaced by target, with a choice of the source (default) or primary repo.

pr_forget() is a new function for abandoning a PR you initiated locally or fetched from GitHub. It only does local clean up and, for example, doesn't delete a remote branch or close a PR (#1263).

pr_view() can now be called with no arguments. If the current branch is associated with an open PR, we target that and, otherwise, we offer an interactive selection.

pr_finish() deletes the remote PR branch if the PR has been merged and the current user has the power to do so, i.e. an external contributor deleting their own branch or a maintainer deleting a branch associated with an internal PR (#1150). It no longer errors if the PR branch has already been deleted (#1196).

pr_pull_upstream() is renamed to pr_merge_main() to emphasize that it merges the main line of development into the current branch, where the main line of development is taken to mean the default branch, as reported by git_branch_default(), of the source repo, which could be either upstream or origin, depending on the situation.

create_from_github() will only create a read-only clone, due to lack of a GitHub personal access token, if explicitly directed to do so via fork = FALSE.

create_from_github() and use_tidy_thanks() accept browser and Git URLs as the repo_spec argument, to be friendlier to copy/paste. When a URL is passed, the host is also extracted from it.

create_github_token() is a new name for the function previously known as browse_github_token() and browse_github_pat().

issue_close_community() and issue_reprex_needed() are two new functions for maintainers who process lots of GitHub issues. They automate canned replies and actions, e.g. labelling or closing (#940).

GitHub Actions is the preferred platform for continuous integration, because that is what the tidyverse team currently uses and maintains. Functions related to Travis-CI and AppVeyor are soft-deprecated to raise awareness about this change and to make it clear that, if substantial maintenance becomes necessary, we may elect to retire the function (#1169).

browse_github_actions() is a new function to open the Actions page of the respective repo on GitHub, similar to existing browse_*() functions (@pat-s, #1102).

use_github_pages() is a new function to activate or reconfigure the GitHub Pages site associated with a repository (#224).

use_tidy_pkgdown() implements the complete pkgdown configuration used by the tidyverse team (#224).

pr_sync() is defunct and can be replicated by calling pr_pull(), pr_merge_main(), then pr_push().

Licensing improvements

All use_*_license() functions now work for projects, not just packages.

use_apl2_license() (not use_apache_license()) and use_gpl3_license() no longer modify the license text (#1198).

use_mit_license() now sets the default copyright holder to "{package} authors". This makes it more clear that the copyright holders are the contributors to the package; unless you are using a CLA there is no one copyright holder of a package (#1207).

New use_gpl_license() and use_agpl_license() make it easier to pick specific versions of the GPL and AGPL licenses, and to choose whether or not you include future versions of the license. Both default to version 3 (and above).

New use_proprietary_license() allows your package to pass R CMD check while making it clear that your code is not open source (#1163). Thanks to @atheriel for the blog post suggesting the wording: https://unconj.ca/blog/copyright-in-closed-source-r-packages-the-right-way.html

use_lgpl_license() now uses version 3 (and above), and gains new version and include_future argument to control which version is used.

use_gpl3_license(), use_agpl3_license() and use_apl2_license() have been deprecated in favour of the new version argument to use_gpl_license(), use_agpl_license() and use_apache_license().

The name argument to use_mit_license() has been changed to copyright_holder to make the purpose more clear. The name argument has been removed from all other license functions because it is not needed; no other license makes an assertion about who the copyright holder is.

RStudio preferences

usethis is now fully cognizant of the changes to RStudio preferences in RStudio 1.3:

edit_rstudio_snippets() looks in the new location, and if you have snippets in the old location, will automatically copy them to the new location (#1204)

New edit_rstudio_prefs() opens RStudio preferences file for editing (#1148).

use_blank_slate() can now configure your global, i.e. user-level, RStudio preference, in addition to project-level (#1018).

Other changes

browse_package() and browse_project() are new functions that let the user choose from a list of URLs derived from local Git remotes and DESCRIPTION (local or possibly on CRAN) (#1113).

The legacy "devtools.desc" option is no longer consulted when populating a new DESCRIPTION file. You must use the "usethis.description" now (#1069).

use_dev_package() gains a remote parameter to allow you to specify the remote. The existing behaviour, which adds an OWNER/REPO GitHub remote, remains the default (#918, @ijlyttle).

use_cpp11() is a new function to set up an R package to use cpp11.

create_package(roxygen = FALSE) once again writes a valid NAMESPACE file (and also has no Roxygen* fields in DESCRIPTION) (#1120).

create_package(), create_project(), create_from_github(), and proj_activate() work better with relative paths, inside and outside of RStudio (#1122, #954).

use_testthat() gains an edition argument to support testthat v3.0.0 (#1185)

use_version() now updates src/version.c if it exists and contains a line matching PKG_version = "x.y.z";.

usethis has been re-licensed as MIT (#1252, #1253).

Dependency changes

New Imports: gert, jsonlite (was already an indirect dependency), lifecycle, rappdirs

No longer in Imports: git2r, rematch2

usethis 1.6.3

Patch release to refactor usage of withr in the tests for forward compatibility with an upcoming withr release. All changes are within the usethis tests.

usethis 1.6.1

Patch release to align some path handling internals with an update coming in the fs package.

  • use_github_links() is a bit more clever about remotes (e.g. origin vs. upstream), which makes it easier to make a PR that adds GitHub links for a package you've forked.

  • use_pkgdown() now .gitignores the destination directory and only adds the destination directory to the config file if it departs from the default (which is docs/).

  • use_tidy_ci() is now deprecated in favour of use_tidy_github_actions() (#1098).

  • use_github_action_check_standard() is a new intermediate workflow that checks on more platforms than _release, but is less exhaustive than _full (@jimhester).

  • create_tidy_package() now uses an MIT license (@topepo, #1096).

usethis 1.6.0

GitHub actions

  • New use_github_actions(), use_github_action_check_release(), use_github_action_check_full(), use_github_action_pr_commands(), to set up GitHub Actions for a package (@jimhester).

  • We now recommend GitHub Actions instead of Travis-CI or AppVeyor, and strongly recommend upgrading your packages.

  • Fix use_github_action() URL parameter to ensure custom URLs are allowed. (@coatless, #1065).

Package creation

  • create_package() gains a roxygen argument. If TRUE (the default), it adds a RoxygenNote field to the DESCRIPTION (which means the first run of devtools::check() will re-document the package, #963), and creates an empty NAMESPACE (which means you'll always need an explicit @export if you want to export functions, #927). It also turns markdown processing on by default (#911).

  • use_rstudio() now sets the LineEndingConversion to Posix so that packages created using usethis always use LF line endings, regardless of who contributes to them (#1002).

  • In the usethis.description option, you can now set Authors@R = person() directly, without having to wrap in additional layer of quotes. If setting this in your .Rprofile, you'll need to use utils::person() since the utils package isn't loaded until after your profile is executed.

PR helpers

  • A new article Pull request helpers demonstrates how to use the pr_*() functions (@mine-cetinkaya-rundel, #802).

  • pr_finish() checks that you don't have any local changes (#805), and can optionally finish any PR, not just the current (#1040).

  • pr_pause() and pr_fetch() now automatically pull to get latest changes (#959, #960) and refresh RStudio's git pane (#706).

  • pr_push() now works for a repository with no open pull requests (@maurolepore, #990).

  • pr_pull() gives more information about which files have merge conflicts and automatically opens conflicted files for editing (#1056).

Other new features

  • New rename_files() makes it easy to rename paired R/ and test/ files (#784).

  • New ui_silence() makes it easier to selectively silence some UI output.

  • New use_agpl3_license() (@pachamaltese, #870).

  • New use_data_table() to set up a package for Import-ing data.table (@michaelchirico, #897).

  • use_latest_dependencies() replaces use_tidy_version() as the new name better reflect its usage (#771).

  • New use_lifecycle() helper to import the lifecycle badges for functions and arguments in your package. Learn more at https://lifecycle.r-lib.org/.

  • use_release_issue() will include additional bullets if your package includes release_bullets() function which returns a character vector (and the package has been loaded with load_all()) (#941).

Minor improvements and bug fixes

  • When writing files, usethis now respects line endings. Default line endings are taken from the .Rproj file (if available), otherwise the DESCRIPTION, otherwise the first file found in R/, then all else failing to your platform default (#767). It should do a better job of preserving UTF-8 files on windows (#969).

  • browse_github() now always goes to the canonical GitHub site: https://github.com/user/repo. This is slightly worse than the current behaviour but makes the function more consistent across packages, and considerably simplifies the implementation.

  • browse_circle() opens the project dashboard on Circle CI.

  • create_download_url() is a new helper for making "ZIP file download" URLs suitable for use with use_course() and use_zip(), starting with the URLs that mere mortals can usually get their hands on in a browser (@fmichonneau, #406).

  • create_package() no longer fails partway through if you have a malformed usethis.description option (#961).

  • create_package() will now create a package in a symlink to a directory (#794).

  • create_package() and use_description() gain a check_name argument to control whether to check for package names invalid for CRAN (@noamross, #883).

  • edit_file() and use_test() gain an open parameter that allows you to control whether or not the function is opened for editing by the user (#817).

  • edit_rstudio_snippets() makes it more clear which snippet types are allowed and that user's snippets mask the built-in snippets (@GegznaV, #885).

  • git_sitrep() now reports project-specific user name and email, if set (#837), and email(s) associated with your GitHub account (@dragosmg, #724).

  • ui_yeah() and ui_nope() allow you to override the default "yes" and "no" strings and to opt-out of shuffling (@rundel, #796).

  • use_circleci() uses correct delimiters in template (@jdblischak, #835).

  • use_circleci_badge() is now exported (@pat-s, #920).

  • use_code_of_conduct() now generates an absolute link to code of conduct on pkgdown website or original source to avoid R CMD check issues (#772).

  • use_course() and use_zip() are now equipped with some retry capability, to cope with intermittent failure or the need for a longer connect timeout (#988).

  • use_data() automatically bumps R dependency to 2.10 (#962).

  • use_data_raw() template quotes the dataset name correctly (#736, @mitchelloharawild).

  • use_description_defaults() now shows the default fields combined with any options that you have set.

  • use_dev_package() now supports packages installed from any remote type, not just GitHub (@antoine-sachet, #1071).

  • use_git() will now create initial commit if needed (#852).

  • use_github_release() no longer fails if you have no news bullets (#1048).

  • use_github_release() now tags the latest local commit instead of the latest remote commit on the default branch (@davidchall, #1029).

  • use_gpl3_license() now completes the license by providing additional information in a file named LICENSE, just like use_mit_license() and friends (@Cervangirard, #683).

  • use_logo() now generates the correct href if the pkgdown url is set (@mitchelloharawild, #986).

  • use_make() gains missing closing parenthesis (@ryapric, #804).

  • use_markdown_template() no longer uses an unexported function in its default arguments (@fmichonneau, #761).

  • use_testthat() and use_test() now work in projects, not just packages (#1017).

  • use_test() works on Windows when called without arguments (#901).

  • use_tidy_issue_template() uses current github format (@Maschette, #756).

  • use_travis(), use_travis_badge(), and browse_travis(), now default to ext = "com" since travis-ci.com is now recommended it over travis-ci.org (@riccardoporreca, #1038).

  • use_release_issue() reminds you to re-generate README.md, if needed (#767).

  • use_r() and use_test() throw a clear error if multiple names are provided (@strboul, #862).

  • use_rcpp() and use_c() now ensure src/ contains at least one .cpp or .c placeholder file, so that the package can be built (@coatless, #720).

  • usethis.destdir is a new option that is consulted when deciding where to put a new folder created by use_course() or create_from_github() (@malcolmbarrett, #1015).

  • use_lifecycle() no longer adds the lifecycle package to the DESCRIPTION file. With the new roxygen markdown syntax for including badges, lifecycle has become a build-time dependency.

Dependency changes

New Imports: cli, rematch2, rlang.

gh minimum version is bumped to v.1.1.0, due to changed behaviour around requests that return nothing.

clisymbols is removed from Imports.

usethis 1.5.1

This is a patch release with various small features and bug fixes.

Using the pipe %>% or the tidy eval toolkit in your package

  • The templates used by use_pipe() and use_tidy_eval() use a more robust form of cross-reference links, linking to files rather than topics. This should silence some warnings seen on Windows at install time (#730, #731 @jmgirard).

  • use_pipe() gains a logical export argument, so it can do the setup necessary to use the pipe operator when it is re-exported (export = TRUE, which is the default and preserves the previous behaviour) and when it is not (export = FALSE) (#783).

Git, GitHub, and pull requests

  • use_github() removes newline \n characters from the description that can cause the initial push to fail (#493, @muschellij2).

  • git_sitrep() gives better feedback if we can't validate the GitHub PAT (#725, @ijlyttle).

  • create_from_github() sets remote tracking branch of master to upstream/master, when it creates (and clones) a fork (#792).

  • pr_pause() can switch back to master even if there is no remote tracking branch (#715, @cderv).

Build tools and continuous integration

  • use_tidy_ci() is updated for R 3.6, meaning that R 3.2 is the oldest version of R supported through proactive testing.

  • use_make() and use_jenkins() add a Makefile and Jenkinsfile, respectively (#501, @ryapric).

  • use_circleci() creates a .circleci/config.yaml config file for CircleCI (#703, @jdblischak).

Other

  • use_zip() is a new variant of use_course() that downloads and unpacks a ZIP file, with less pedantic behaviour re: the destination directory. Both functions now also work for ZIP files with MIME type "application/x-zip-compressed" (#573).

  • use_version() can detect "(development version)" in a NEWS header and update it with an actual version (#768, @DavisVaughan).

Dependency changes

R 3.1 is no longer explicitly supported or tested. Our general practice is to support the current release (3.6, at time of writing), devel, and the 4 previous versions of R (3.5, 3.4, 3.3, 3.2).

fs minimum version is stated to be v1.3.0.

glue minimum version is stated to be v1.3.0.

usethis 1.5.0

Git, GitHub (and GitLab)

usethis gains several functions to inspect and manipulate the Git situation for the current project = repository. We also provide more control and visibility into git2r's workings, especially around credentials (usethis uses git2r for all Git operations).

  • git_sitrep() lets you know what's up with your Git, git2r and GitHub config (#328).

  • git_vaccinate() vaccinates your global (i.e. user-level) git ignore file. It adds standard entries for R users, such as .Rhistory and .Rdata. This decreases the chance that you commit and push files containing confidential information (#469).

  • git_remotes() and use_git_remote() are new helpers to inspect or modify Git remote URLs for the repo associated with the active project (#649).

  • git_protocol() + use_git_protocol() and git_credentials() + use_git_credentials() are new helpers to summon or set Git transport protocol (SSH or HTTPS) or git2r credentials, respectively. These functions are primarily for internal use. Most users can rely on default behaviour. Use these helpers to intervene if git2r isn't discovering the right credentials (#653). usethis honors the usethis.protocol option, which allows you to express a general preference for SSH vs. HTTPS.

Other improvements and bug fixes:

  • use_github() tries harder but also fails earlier, with more informative messages, making it less likely to leave the repo partially configured (#221).

  • use_github() and create_from_github() gain a protocol argument (#494, @cderv).

  • create_from_github() pulls from upstream master in a fork (#695, @ijlyttle).

  • use_release_issue() creates a GitHub issue containing a release checklist, reflecting the standard practices of the tidyverse team (#338).

  • use_github_release() creates a draft GitHub release using the entries in NEWS.md (#137).

  • use_gitlab_ci() creates a gitlab-ci.yaml config file for GitLab CI (#565, @overmar).

  • use_git_config() now invisibly returns the previous values of the settings.

  • use_github_labels() has been rewritten be more flexible. You can now supply a repo name, and descriptions, and you can set colours/descriptions independently of creating labels. You can also rename existing labels (#290).

GitHub pull requests

We've added experimental functions to work with GitHub pull requests. They are aimed at both a maintainer (who may make, review, and modify pull requests) and a contributor (who may make or explore pull requests).

  • git_sitrep() includes a section at the end aimed at describing "pull request readiness". Expect that to develop and expand.

  • pr_init(), pr_fetch(), pr_push(), pr_pull(), pr_finish(), and pr_view() constitute the new family of helpers. They are designed to be smart about the significance of remotes with the standard names of origin and upstream and to facilitate both internal and external pull requests.

Partial file management

usethis gains tooling to manage part of a file. This is currently used for managing badges in your README and roxygen import tags:

  • use_badge() and friends now automatically add badges if your README contains a specially formatted badge block (#497):

    <-- badge:start -->
<-- badge:end -->

  • use_tibble() and use_rcpp() automatically add roxygen tags to to {package}-package.R if it contains a specially formatted namespace block (#517):

    ## usethis namespace: start
## usethis namespace: end
NULL

    Unfortunately this means that use_rcpp() no longer supports non-roxygen2 workflows, but I suspect the set of people who use usethis and Rcpp but not roxygen2 is very small.

Extending and wrapping usethis

  • New proj_activate() lets you activate a project, either opening a new RStudio session (if you use RStudio) or changing the working directory (#511).

  • proj_get() and proj_set() no longer have a quiet argument. The user-facing message about setting a project is now under the same control as other messages, i.e. getOption("usethis.quiet", default = FALSE) (#441).

  • A new set of ui_*() functions makes it possible to give your own code the same user interface as usethis (#308). All use the glue and crayon and packages to power easy interpolation and formatting. There are four families of functions:

    • block styles: ui_line(), ui_done(), ui_todo(), ui_oops(), ui_info().
    • conditions: ui_stop(), ui_warn().
    • questions: ui_yeah(), ui_nope().
    • inline styles: ui_field(), ui_value(), ui_path(), ui_code().

  • with_project() and local_project() are new withr-style functions to temporarily set an active usethis project. They make usethis functions easier to use in an ad hoc fashion or from another package (#441).

Tidyverse standards

These standards are (aspirationally) used by all tidyverse packages; you are welcome to use them if you find them helpful.

  • Call use_tidy_labels() to update GitHub labels. Colours are less saturated, docs is now documentation, we use some emoji, and performance is no longer automatically added to all repos (#519). Repo specific issues should be given colour #eeeeee and have an emoji.

  • Call use_logo() to update the package logo to the latest specifications: man/figure/logo.png should be 240 x 278, and README should contain <img src="man/figures/logo.png" align="right" height="139" />. This gives a nicer display on retina displays. The logo is also linked to the pkgdown site if available (#536).

  • When creating a new package, use create_tidy_package() to start with a package following the tidyverse standards (#461).

  • NEWS.md for the development version should use "(development version)" rather than the specific version (#440).

  • pkgdown sites should now be built by travis and deployed automatically to GitHub pages. use_pkgdown_travis() will help you set that up.

  • When starting the release process, call use_release_issue() to create a release checklist issue (#338).

  • Prior to CRAN submission call use_tidy_release_test_env() to update the test environment section in cran-comments() (#496).

  • After acceptance, try use_github_release() to automatically create a release. It's created as a draft so you have a chance to look over before publishing.

  • use_vignette() includes the a standard initialisation chunk with knitr::opts_chunk$set(comment = "#>", collapse = TRUE) which should be used for all Rmds.

  • use_tutorial() creates a new interactive R Markdown tutorial, as implemented by the learnr package (@angela-li, #645).

  • use_article() creates articles, vignettes that are automatically added to .Rbuildignore. These appear on pkgdown sites, but are not included with the package itself (#281).

  • use_citation() creates a basic CITATION template and puts it in the right place (#100).

Other minor bug fixes and improvements

  • write_union() appends the novel lines, but does not remove duplicates from existing lines (#583, @khailper).

  • use_rcpp("foo") now creates src/foo.cpp (#117).

  • use_data() gains a version argument and defaults to serialization format version 2 (#675).

  • use_data_raw() accepts a name for the to-be-prepared dataset and opens a templated R script (#646).

  • browse_github() now falls back to CRAN organisation (with a warning) if package doesn't have its own GitHub repo (#186).

  • use_news_md() will optionally commit.

  • use_package() gains a min_version argument to specify a minimum version requirement (#498). Set to TRUE to use the currently installed version (#386). This is used by use_tidy_eval() in order to require version 0.1.2 or greater of rlang (#484).

  • use_pkgdown() is now configurable with site options (@jayhesselberth, #467), and no longer creates the docs/ directory (#495).

  • use_version("dev") now creates a standard "(development version)" heading in NEWS.md (#440).

  • use_vignette() now checks if the vignette name is valid (starts with letter and consists of letters, numbers, hyphen, and underscore) and throws an error if not (@akgold, #555).

  • restart_rstudio() now returns FALSE in RStudio if no project is open, fixing an issue that caused errors in helpers that suggest restarting RStudio (@gadenbuie, #571).

Dependency changes

  • withr moves from Suggests to Imports.

  • purrr and yaml are new in Imports.

usethis 1.4.0

File system

All usethis file system operations now use the fs package (#177). This should not change how usethis functions, but users may notice these features of fs-mediated paths:

  • Paths are "tidy", meaning / is the path separator and there are never multiple or trailing /.
  • Paths are UTF-8 encoded.
  • A Windows user's home directory is interpreted as C:\Users\username (typical of Unix-oriented tools, like Git and ssh; also matches Python), as opposed to C:\Users\username\Documents (R's default on Windows). Read more in fs::path_expand().

Extending or wrapping usethis

These changes make it easier for others to extend usethis, i.e. to create workflow packages specific to their organization, or to use usethis in other packages.

  • proj_path() is newly exported. Use it to build paths within the active project. Like proj_get() and proj_set(), it is not aimed at end users, but rather for use in extension packages. End users should use rprojroot or its simpler companion, here, to programmatically detect a project and build paths within it (#415, #425).

    • edit_file(), write_over(), and write_union() are newly exported helpers. They are mostly for internal use, but can also be useful in packages that extend or customize usethis (#344, #366, #389).

  • use_template() no longer errors when a user chooses not to overwrite an existing file and simply exits with confirmation that the file is unchanged (#348, #350, @boshek).

  • getOption("usethis.quiet", default = FALSE) is consulted when printing user-facing messages. Set this option to TRUE to suppress output, e.g., to use usethis functions quietly in another package. For example, use withr::local_options(list(usethis.quiet = TRUE)) in the calling function (#416, #424).

New functions

  • proj_sitrep() reports current working directory, the active usethis project, and the active RStudio Project. Call this function if things seem weird and you're not sure what's wrong or how to fix it. Designed for interactive use and debugging, not for programmatic use (#426).

  • use_tibble() does minimum setup necessary for a package that returns or exports a tibble. For example, this guarantees a tibble will print as a tibble (#324 @martinjhnhadley).

  • use_logo() resizes and adds a logo to a package (#358, @jimhester).

  • use_spell_check() adds a whitelist of words and a unit test to spell check package documentation during R CMD check (#285 @jeroen).

Other small changes and bug fixes

  • usethis has a new logo! (#429)

  • use_course() reports progress during download (#276, #380).

  • use_git() only makes an initial commit of all files if user gives explicit consent (#378).

  • create_from_github(): the repo argument is renamed to repo_spec, since it takes input of the form "OWNER/REPO" (#376).

  • use_depsy_badge() is defunct. The Depsy project has officially concluded and is no longer being maintained (#354).

  • use_github() fails earlier, with a more informative message, in the absence of a GitHub personal access token (PAT). Also looks for the PAT more proactively in the usual environment variables (i.e., GITHUB_PAT, GITHUB_TOKEN) (#320, #340, @cderv).

  • The logic for setting DESCRIPTION fields in create_package() and use_description() got a Spring Cleaning. Fields directly specified by the user take precedence, then the named list in getOption("usethis.description") is consulted, and finally defaults built into usethis. use_description_defaults() is a new function that reveals fields found in options and built into usethis. Options specific to one DESCRIPTION field, e.g. devtools.desc.license, are no longer supported. Instead, use a single named list for all fields, preferably stored in an option named "usethis.description" (however,"devtools.desc" is still consulted for backwards compatibility). (#159, #233, #367)

Dependency changes

New Imports: fs, glue, utils

No longer in Imports: backports, httr, rematch2, rmarkdown (moved to Suggests), styler (moved to Suggests)

usethis 1.3.0

  • usethis has a website: https://usethis.r-lib.org (#217). It includes an article with advice on system setup, for usethis and for R development more generally.

  • edit_*() functions now return the target path, invisibly (#255).

  • edit_git_ignore(scope = "user") prefers ~/.gitignore, but detects an existing ~/.gitignore_global, if it exists. If a new global gitignore file is created, it is created as ~/.gitignore and recorded in user's git config as the core.excludesfile (#255).

  • create_from_github() gains several arguments and new functionality. The protocol argument lets user convey whether remote URLs should be ssh or https. In the case of "fork and clone", the original repo is added as upstream remote. It is now possible -- although rarely necessary -- to directly specify the GitHub PAT, credentials (in git2r form), and GitHub host (#214, #214, #253).

  • use_github_labels() can create or update the colour of arbitrary GitHub issue labels, defaulting to a set of labels and colours used by the tidyverse packages, which are now exposed via tidy_labels(). That set now includes the labels "good first issue" and "help wanted" (#168, #249).

  • appveyor_info() no longer reverses the repo's URL and image link. Corrects the markdown produced by use_appveyor_badge() (#240, @llrs).

  • use_cran_badge() uses an HTTPS URL for the CRAN badge image (#235, @jdblischak).

  • create_package() and create_project() return a normalized path, even if target directory does not pre-exist (#227, #228).

New functions

  • use_git_config() can set user's Git name or email, globally or locally in a project/repo (#267).

  • browse_github_pat() goes to the webpage where a GitHub user can create a personal access token (PAT) for the GitHub API. If the user configures a PAT, they can use functions like create_from_github() and use_github() to easily create and connect GitHub repos to local projects. (#248, #257, @jeroen, via @jennybc).

  • use_version() increments the version of the active package, including an interactive chooser. use_dev_version() is now a special case wrapper around this. (#188, #223, @EmilHvitfeldt).

  • use_tidy_github() creates a standard set of files that make a GitHub repository more navigable for users and contributors: an issue template, contributing guidelines, support documentation, and a code of conduct. All are now placed in a .github/ subdirectory (#165, @batpigandme).

  • use_bioc_badge creates a Bioconductor badge that links to the build report (#271, @LiNk-NY).

  • use_binder_badge() creates a badge indicating the repository can be launched in an executable environment via Binder (#242, @uribo).

usethis 1.2.0

New functions

  • use_course() downloads a folder's worth of materials from a ZIP file, with deliberate choices around the default folder name and location. Developed for use at the start of a workshop. Helps participants obtain materials from, e.g., a DropBox folder or GitHub repo (#196).

  • use_blank_slate() provides a way to opt in to an RStudio workflow where the user's workspace is neither saved nor reloaded between R sessions. Automated for scope = "project". Provides UI instructions for scope = "user", for now (#139).

  • use_tidy_style() styles an entire project according to https://style.tidyverse.org (#72, #197 @lorenzwalthert).

  • GitHub conventions common to tidyverse packages are enacted by use_tidy_contributing(), use_tidy_issue_template(), and use_tidy_support() (@batpigandme, #143, #166).

Other changes

  • New projects that don't exhibit other obvious criteria for being a "project" will include a sentinel, empty file named .here, so they can be recognized as a project.

  • Project launching and switching works on RStudio server (#115, #129).

  • use_template() is newly exported, so that other packages can provide templating functions using this framework (@ijlyttle #120).

  • use_readme_rmd() and use_readme_md() work, in a similar fashion, for projects that are and are not a package (#131, #135).

  • use_readme_rmd() once again creates a pre-commit git hook, to help keep README.Rmd and README.md in sync (@PeteHaitch #41).

  • Substantial increase in unit test coverage.

usethis 1.1.0

New helpers

  • browse_github(), browse_github_issues(), browse_github_pulls(), browse_cran() and browse_travis() open useful websites related to the current project or a named package. (#96, #103).

  • create_from_github() creates a project from an existing GitHub repository, forking if needed (#109).

  • use_cc0_license() applies a CC0 license, particularly appropriate for data packages (#94)

  • use_lifecycle_badge() creates a badge describing current stage in project lifecycle (#48).

  • use_pkgdown() creates the basics needed for a pkgdown website (#88).

  • use_r("foo") creates and edit R/foo.R file. If you have a test file open, use_r() will open the corresponding .R file (#105).

  • use_tidy_versions() sets minimum version requirement for all dependencies.

Bug fixes and improvements

  • use_dev_version() now correctly updates the Version field in a package description file. (@tjmahr, #104)

  • use_revdep() now also git-ignores the SQLite database (#107).

  • use_tidy_eval() has been tweaked to reflect current guidance (#106)

usethis 1.0.0

This is a new package that extracts out many functions that previously lived in devtools, as well as providing more building blocks so you can create your own helpers. As well as the many new helpers listed below, there are three main improvements to the package:

  • More support for general R projects, other than packages.
  • A notion of an "active" project that all commands operate on.
  • Refined output.

usethis is gradually evolving towards supporting more general R "projects", not just packages. This is still a work in progress, so please let me know if you use a function that you think should work with projects but doesn't. You can also try out the new create_project() which creates a basic RStudio project.

The concept of the working directory and the "base path" have been refined. Rather than using an argument to specify the active project, all use_ functions now use a global active project setting, as returned by proj_get(). This is cached throughout a session, although it will be updated by create_package() and create_project(). You'll now get an clear error if you attempt to use_something() outside of a project, and create_something() will warn if you're trying to create inside an existing project.

The output from all usethis commands has been reviewed to be informative but not overwhelming. usethis takes advantage of colour (using crayon and RStudio 1.1) to help chunk the output and clearly differentiate what you need to do vs. what has been done for you.

New functions

  • use_apl2_license() if you want to use the Apache 2.0 license.

  • use_depsy_badge() allows including a Depsy badge (@gvegayon, #68).

  • use_dev_package() works like use_package() but also adds the repo to the Remotes field (#32).

  • use_github_labels() will automatically set up a standard set of labels, optionally removing the default labels (#1).

  • use_pipe() creates a template to use magrittr's %>% in your package (#15).

  • use_tidy_ci() which sets up travis and codecov using the tidyverse conventions (#14)

  • use_tidy_description() puts description fields in a standard order and alphabetises dependencies.

  • use_tidy_eval() imports and re-exports the recommend set of tidy eval helpers if your package uses tidy eval (#46).

  • use_usethis() opens your .Rprofile and gives you the code to copy and paste in.

New edit functions

A new class of functions make it easy to edit common config files:

  • edit_r_profile_user() opens .Rprofile
  • edit_r_environ_user() opens .Renviron
  • edit_r_makevars_user() opens .R/Makevars
  • edit_git_config_user() opens .gitconfig
  • edit_git_ignore_user() opens .gitignore
  • edit_rstudio_snippets(type) opens ~/R/snippets/{type}.snippets

Updates

  • use_coverage("codecov") now sets a default threshold of 1% to try and reduce false positives (#8).

  • use_description() now sets ByteCompile: true so you can benefit from the byte compiler (#29)

  • The license functions (use_mit_license(), use_apl2_license(), and use_gpl3_license()) save a copy of the standard license text in LICENSE.md, which is then added to .Rbuildignore. This allows you to follow standard licensing best practices while adhering to CRANs requirements (#10).

  • use_package_doc() uses more a modern roxygen2 template that requires less duplication.

  • use_test() will use the name of the currently open file in RStudio if you don't supply an explicit name (#89).

  • use_readme_rmd() now puts images in man/figures/ and no longer adds to .Rbuildgnore. This ensures that the rendered README.md will also work on CRAN (#16, #19). The first chunk now uses include = FALSE and is named setup (#19).

  • use_revdep() creates structure for use with revdepcheck package, the preferred way to run revdepchecks. (#33)

Building blocks

  • New use_badge() for adding any badge to a README. Now only prints a todo message if the badge does not already exist.

  • use_directory() is now exported (#27).

Bug fixes and minor improvements

  • Functions which require code to be copied now automatically put the code on the clipboard if it is available (#52).

  • create_package() no longer creates a dependency on the current version of R.

  • use_build_ignore() now strips trailing /

  • use_git() will restart RStudio if needed (and possible) (#42).

  • use_github() now has an organisation parameter so you can create repos in organisations (#4).

  • use_template() and use_test() now convert title to a slug that only contains lowercase letters, numbers, and -.

  • use_vignette() now adds *.html and *.R to your .gitgnore so you don't accidentally add in compiled vignette products (#35).

  • use_travis_badge() and use_appveyor_badge() are now exported functions, so they can be used even if ci was separately set up (#765, @smwindecker).
