`xml.parsers.expat.ExpatError` after install

After installing JSCustom via Package Control I immediately get the following error (included package install as well for context):

reloading plugin JSCustom.plugin
JS Custom: New installation. Building all syntaxes.

Also, when I open up the JSCustom preferences and try to save I get the message:

Unable to save ~/Library/Application Support/Sublime Text 3/Packages/JSCustom/sublime/JS Custom.sublime-settings
Error: No such file or directory

~ is /Users/malthe. ~/Library/Application Support/Sublime Text 3/Packages/JSCustom/ doesn't exist. ~/Library/Application Support/Sublime Text 3/Packages/User/JS Custom/Syntaxes/ exists but is empty.

The first part was caused by the package AutoDocstring, specifically Packages/AutoDocstring/ADMagicPython.hidden-tmLanguage. Removing the AutoDocstring-package fixed the issue.

Second part with the "unsaveable" settings seems intended. Closing issue.

Were you editing the default settings (on the left) rather than the user settings (on the right)? It sounds like you've worked it out either way.

[malthejorgensen]

Yes, exactly that. I was desperately trying to get it to work, but didn't know it was all caused by the first error with AutoDocstring at the time 😅

[malthejorgensen]

Not sure if this is deserving of a new issue (or we should rather wait for Sublime Text 4 to land) but I'm having some issues with syntax highlighting. Seems to be caused by the multiline generic args to reduxForm:

Is that Flow or TypeScript?

TypeScript support in 2.4 is experimental and not super great. Version 3.0 offers much better TypeScript support (developed in concert with the new core TypeScript syntax) but relies on ST4 features. If you're on the ST4 beta, you can get the latest JS Custom 3.0 alpha by adding "install_prereleases": ["JSCustom"] to your Package Control config.

If that's Flow, then honestly the Flow extension is going to need an almost complete rewrite for 3.0, which I haven't begun. The 3.0 TypeScript extension might actually provide better highlighting for Flow at this point.

The problem in this case is that the 2.4 extensions don't know about generic type parameters to functions. This is very difficult to do without the new ST4 syntax features and I doubt that I'll ever make them work for a ST3-compatible release.

[malthejorgensen]

This is TypeScript – sounds good – I was planning to upgrade to the beta of Sublime Text 4 anyways, so will do that in the coming days :)
