- Add node_type field to Scope class to track treesitter node type
- Pass node_type from chunkHelper to render function
- Add node_type_styles config option for pattern-based style mapping
- Create dynamic highlight groups based on node type patterns
- Also includes virt_text_repeat_linebreak fix for wrapped lines
Example config:
node_type_styles = {
["^func"] = { fg = "#99aee5" }, -- functions: blue
["^if"] = { fg = "#c2a2e3" }, -- conditionals: purple
["^for"] = { fg = "#fbdf90" }, -- loops: yellow
}
This allows different colored chunk indicators for different scope types
(functions, loops, conditionals, etc.) when use_treesitter is enabled.
- Add nix.lua with Nix-specific treesitter node types - Enables chunk indicators for let expressions, attrsets, lambdas, etc. - Provides better visual feedback for Nix flake structure This allows hlchunk to show arrows/indicators for all nested scopes in Nix files (inputs, outputs, let blocks, attribute sets, etc.) instead of just top-level scopes.

Summary
Adds Nix-specific treesitter node types for better chunk indicator support in Nix files.
Problem
Currently, hlchunk only shows chunk indicators for top-level scopes in Nix files. Nix has many nested scope types (let expressions, attribute sets, lambda functions, etc.) that weren't being detected.
Solution
Add
nix.luawith Nix-specific treesitter node types as a table (not array):let_expression-let ... in ...blocksattrset_expression-{ ... }attribute setsrec_attrset_expression-rec { ... }recursive setslist_expression-[ ... ]listslambda_expression-arg: bodyfunctionsfunction_expression-{ args }: bodyfunctionswith_expression-with ...; ...expressionsif_expression- conditionalsassert_expression- assertionsbinding-name = value;bindingsBenefits
Better visual feedback when editing Nix flakes and configurations. Users can now see chunk indicators for:
Especially useful for NixOS configurations and flake structures.
Testing
Tested on NixOS with Nix flakes and configuration files. Chunk indicators now appear for all nested scopes.
