NeoCodeMap

This plugin is inspired by sublime-codemap but using Sublime Text 4 capabilities.

It displays on the side of the editor. You can jump to symbol definition and references to it.

It supports all languages through native Sublime indexing.

Specific languages features

Generic

Nesting level is guessed through indentation level.

Markdown

The package supports markdown headings.

Make your own

You can make your own Indenter and register it with register_indenter.

This looks like this for a markdown indenter:

import sublime
from CodeMapManager import indenter

def my_markdown_indenter(view: sublime.View, symbol: sublime.SymbolRegion) -> int:
	# process stuff
	return x

indenter.register_indenter("text.html.markdown", my_markdown_indenter)

The last registered indenter takes priority.

You can even override the default indenter by overriding None.

import sublime
from CodeMapManager import indenter

def my_default_indenter(view: sublime.View, symbol: sublime.SymbolRegion) -> int:
	# process stuff
	return x

indenter.register_indenter(None, my_default_indenter)
