No effect of .bnf and .flex files Follow
I am creating plugin for custom language development and I do not understand how .bnf and .flex files work
Help me find out what is wrong
My project structure is showed below.
When I run plugin and creating a.eo with content from JetBrains example (the end of page) I see this text without any changes. I tried to rebuild project and still don't understand the reason of that.
Here is how I see it. I expected to see grey lines with comments but I see it as other text. EO.bnf and EO.flex are also from JetBrains tutorial
Please sign in to leave a comment.
It is hard to understand the issue without more information. Please share the link to the repository if the plugin is open source, or provide more files like build.gradle.kts (+ related), plugin.xml, BNF, and Flex files.
upd: I checked PSI of .eo file. It detects comments and all tokens but it doesn't colours comments
