It's time for the next release of IHP: v24072020 🎉 Since the last release we have merged 85 commits by 8 contributors..

Major Changes

Improved DEFAULT support in createRecord: Previously createRecord was always using the sql default value when a column had a default value defined in the database schema. This means that calling project |> set #name "My new project" |> createRecord would do a INSERT INTO projects (id, name, user_id) VALUES (DEFAULT, DEFAULT, ...); instead of using the given My new project name for the project. The sql default value is now only used when it's not overriden. Thanks to @ruhatch 🎉
updateRecord only updates changes fields: Previously updateRecord was always doing an UPDATE query where it was setting all fields. Now the UPDATE query will only update columns that have been changed using |> set #someField someValue on the record. Thanks to @ruhatch 🎉
Inline JS and CSS in HSX: Previously code like [hsx|<style>h1 { color: blue}</style>|] would trigger a parser error. This is now fixed and the inline <style> tag is rendered as expected. Same with the <script> tag.
Void tags like <br>, <input>, <hr> supported in HSX: Previously void tags (tags without a closing tag </tag>) needed to be written in xhtml style (<br /> instead of <br>). By @ruhatch
Troubleshooting Guide: Our GitHub Wiki got a new section on Troubleshooting. This might help people to find solutions to IHP problems faster when googling the error message.

Minor Changes

In rendered date times the string Uhr (german for "time") has been removed (by @nghamilton)
Optional param functions like paramOrNothing now return Nothing when the param parser fails to parse an empty string (by @nghamilton)
Code Generators offer a select box to chose the application when working with multiple applications in a single project
Previously when a form was submitted in IHP, but the server rendered a server error, the error page was not shown to the user. This is fixed now.
Fixed controller generator generating code without table fields when there is an "_" in the table name
New documentation section: How to update IHP?
The IHP setup process has now improved support for dealing with PATH variables that have spaces in the PATH string. This improves the situation a lot for windows users. Thanks @adithyaov 🎉
The api docs have been improved: The haddock quickjump index is now working as expected :)
HSX now works with HTMX and Ionicons (by @ruhatch)
Lots of grammar and spelling mistakes have been fixed in the documentation (by @chrislf)
Missing InputValue and ParamReader instances for Day type have been added
A new function includes has been added to IHP.HaskellSupport as an alias for elem
A new function didChangeRecord has been added that returns True when a record has unsaved changes
A new function didChange #someField someRecord has been added that returns True when a field of record has unsaved changes

To update the IHP version of your project, open default.nix and change the git commit in line 4 to the following:

rev = "75ea02f8520f4fe1ca02ddfa6901dda8ca246955";

After that run the following command to update your project:

nix-shell -j auto --cores 0 --run 'make -B .envrc'

In case nix starts rebuilding IHP (might take a while), make sure cachix is set up as expected:

cachix use digitallyinduced

Now you can start your project as usual with ./start.

If you have any problems with updating, let us know on Gitter.

📅 The next release is expected to be released on 07.08.2020.
