OS: Windows 10 Pro
IDE: IntelliJ IDEA Community 2018.3 RC (build 183.4284.118)
Plugin version: 1.0.0-beta12
Project opened: owo-lang/OwO@539849b

[ice1000]

Ooops, I was opening the cabal file instead of the project.

[ice1000]

This can't be the reason for the plugin to crash, tho.

[rikvdkleij]

You will have to open the folder of the project (which contains the stack.yaml).

And it is better to use the latest beta of the plugin. See readme how to install.

I'll try out the beta version.

That crash should be prevented in the latest betas.

Yes, I just installed and realized that.
Thanks for the great work!

BTW: are you interested in replacing the current icon with a more IntelliJ-styled one (placing the language icon at the right-bottom corner like this )? I'm willing to help.
BTW: any reason for not highlighting qualified and as as keywords? I'm willing to add an annotator to highlight them.

Thank you but the current icon is okay for me

BTW: any reason for not highlighting qualified and as as keywords? I'm willing to add an annotator to highlight them.

qualified and as are not highlighted as keywords because it depends on context. For example, it is allowed to create function which has name qualified. They are not defined in the lexer so I can not refer to them as token as is how the IntelliJ syntax highlighting works.

[ice1000]

I know what you mean, but I know how to highlight them contextually.
Will implement and submit PR soon :)

[ice1000]

Close as fixed in beta build
