@axelson - I have observed that with Elixir 1.13.3, suddenly, the ~H sigils inside the *.ex files are getting formatted on save in VS Code. However, the same is not happening for *.heex files. I could not understand why so. Can you please explain?

I’d say that is because ~H is delegated to the mix format plugin while *.heex is not handled at all by mix format.

Hmm… but, if I run mix format from command line, even *.heex files are getting formatted correctly.

I also struggled to have the formatter automatically running in a consistent way and noticed mix format does the trick, so just went ahead and created a manual task and keybinding to move on for now until I can get time to revisit the issue.
In tasks.json
{
"label": "mix format",
"type": "shell",
"command": "mix",
"args": [
"format",
"${file}"
],
"presentation": {
"echo": false,
"reveal": "silent",
"focus": false,
"panel": "shared",
"showReuseMessage": false,
"clear": false
}
},
and in keybindings.json
{
"key": "shift+alt+f",
"command": "workbench.action.tasks.runTask",
"args": "mix format",
"when": "editorTextFocus && editorLangId =~ /html-eex|elixir|phoenix-heex/"
},

Another technique I used is
Install the extension emeraldwalk.runonsave
In VS Code’s settings.json, add an entry like this:
"emeraldwalk.runonsave": {
"commands": [
{
"match": "\\.heex|ex?$",
"isAsync": true,
"cmd": "cd ${workspaceRoot} && mix format ${file}"
}
]
},

Hi everyone!
We have just merged this PR: Update readme instructions for clarity by axelson · Pull Request #55 · feliperenan/heex_formatter · GitHub which not only refactor the code but improves how the code is going to be formatted.
Please, give it a try and let me know about any issue you may face. Also, notice that you might get some difference from how it has been formatting before.
PS: In case you don’t want to update it, I’ve created a git tag for previous version. But I really recommend you to try out the latest version 
Thanks

I have just noticed I linked the wrong PR. Here is the one I meant.

Hello,
Are you planning to publish on hex.pm?
That one breaks dependabot that is unable to get the package from github.

Thanks for the update and good job!
I guess it’s not recommended to use it anymore, right?
Any documentation on how to make it work from Phoenix, or it’ll be automatically added in the boilerplate for new projects in the next version, maybe?
