Description

This layer provides bindings for using Cscope and PyCscope in Spacemacs.

Cscope provides indexing and searching capabilities for C and C++ code. PyCscope extends these capabilities for Python code as well. See here for a comparison between Cscope and other similar tools (such as gtags).

Install

Layer

To use this configuration layer, add it to your ~/.spacemacs. You will need to add cscope to the existing dotspacemacs-configuration-layers list in this file.

Cscope

Install Cscope through your package manager, or download it from the website and build it from source.

From package manager (for example, Ubuntu):

sudo apt-get install cscope

From source:

tar xvf cscope-15.8b
cd cscope-15.8b
./configure
make
sudo make install

PyCscope

Install PyCscope through pip:

pip install pycscope

Usage

Before using any helm-cscope commands, remember to create a Cscope index file. Do it by running the command cscope-index-files for C and C++ projects, or the command cscope/run-pycscope for Python projects, bound to SPC m g i.
