File Nesting a la JetBrains

[bennypowers]

Jetbrains (webstorm, etc) has a feature where file entries in the tree can collapse into one another. For example, a user can configure the tree to show *.ts files as a subtree, with siblings matching $1.d.ts $1.js and $1.js.map as the subtree's children:

This would be a cool feature in neo-tree. I'm wondering if maintainers and contributors think this could be easily accomplished in userland?

That is really cool! You can probably hack it in in an after_render event, but this is best done as a change to the internal code. I'm going to create an issue for this and put it on the to-do list.

here's some jb docs on the configuration

I'd imagine something like

file_nesting = {
  "ts": { "cjs", "cjs.map", "js", "js.map", "d.ts" },
},
