🔎 codesearch

Search for patterns and phrases in your git repository code base.

All this tool is is a glorified and sugar-coated egrep. However, the difference it makes in productivity and getting around a code base is surprising.

Installation

$ brew update  # optional
$ brew install agyorev/tools/codesearch

Use Case

Let's take an example where the tools really shines. Say you're trying to find out how some RPC action, called 'editUser' maps from a JavaScript frontend to a Python backend.

You can first search for all of the occurrences of 'editUser' in your js files, like:

$ codesearch -e js -p "'editUser'"

Then you can look up the same string literal, with some context around it, in your Python files, and see where the action is being registered:

$ codesearch -e py -c 1 -p "'editUser'"

Or maybe you want to look up all of the edit* actions. In this case just use a normal regular expression:

$ codesearch -e py -c 1 -p "'edit[^']+'"

Config (optional)

In case you don't want to look through your whole git repository, maybe there are some irrelevant folders (node_modules, for example), or you don't want to look through all file types.

If this sounds like something you'd like, you should create a file called codesearch.yaml and put it in the root of your git repository.

Currently the following properties are allowed:

extensions:  # only match against files with these extensions, unless specifically set with the -e option.
  - ...

include_folders:  # only show matches from the following folders
  - ...

exclude_folders:  # exclude all files from the following folders from the search
  - ...

You can check out the example config file, for reference.

Usage

Run within a git repository folder.
