gem context_grep

It passes the query to the underlying grep (or ripgrep, if installed), and then prints not just "N lines of context" like you usually do, but the chains of syntactic parent lines for each match.

Installation:

$ brew install icu4c       # for github-linguist, install in the way according to your system
$ gem install context_grep

Usage:

$ cogrep something

Examples:

1. it skips unsupported grammars

   ruby-tree-sitter $ cogrep segfa
                                                                               
   unsupported grammar Markdown at ./docs/SIGSEGV.md
   
   ./ext/tree_sitter/node.c
    308 static VALUE node_field_name_for_child(VALUE self, VALUE idx) {
    311   // this way to avoid segfault. Should we absolutely stick to the original API?
   
   ./Rakefile
     13 # NOTE: bundler is segfaulting on:
   
   ./test/tree_sitter/node_test.rb
    121 describe 'parent' do
    122   # NOTE: never call parent on root. It will segfault.
   

2. demonstrates how

   1. it merges multiple matched lines from one file
   2. it relies on actual syntax, not indentation
   3. to run it with ruby >= 3.1 (required for the gem ruby_tree_sitter) if your local is lower, in case of rbenv
   

Currently it passes . as grep input.
