replace

Easy to use cross-platform regex replace command line util. Can't remember the arguments to the find command? or how xargs works? Maybe sed is a little different on your Mac than in Linux?

Forget all that stuff and just replace string newval **/*.dart

This tool is pretty basic and there aren't a lot of safeguards. It can run recursively and replace things in files that weren't intended. Use caution when replacing. It's meant to be used in a directory under source control so you can see what files have been changed using a diff.

It ignores dotfiles (especially the .git directory) except these

• .gitignore
• .pubignore
• .travis.yml
• .travis.yaml

Globs don't seem to go into dotfile directories by default so if you want to do that, just include another glob in the command for those (Ex: replace fish zebra .github/**.md **/*.md)

If you need to replace in dotfiles other than these, you can submit a PR to this repo to allow it or work around it by renaming the file, replacing, and renaming it back.

Installing

pub global activate replace

or more advanced install

• clone the project
• pub get
• dart compile exe bin/replace.dart -o replace
• Place the replace executable in your path

Running / Usage

replace <regexp> <replacement> <glob_file_or_dir> ...

This means you can pass as many globs, directory names, or filenames as the 3rd and after paramter. This works nicely with glob expansion if your shell supports it. Example replace aword replacementword **/*.md

If you're having problem with your shell interpreting characters as shell control characters, and or you need spaces in your regex or replacement, you can use quotes and noglob.

Example: noglob replace "key & peele" "ren || stimpy" **/*.md

Regexes and globs are Dart style Glob Syntax: https://pub.dev/packages/glob#syntax

The replacement may contain references to the capture groups in regexp using a backslash followed by the group number. Backslashes not followed by a number return the character immediately following them.

More Examples:

Simple strings and filename replace word "lots of words" menu.txt

Regex and glob (w/ quotes around arguments) replace "(war).*(worlds)" "\1 of the monkeys" **

Match a word at the beginning of a line replace "^chowder" soup menu.txt

Match a word at the end of a line replace "dessert$" cookies menu.txt
