Csope

C source code browser. Fork of Cscope version 15.9, with various improvements.

Because CScope is good and shall not be forgotten. While the original's maintenance seems abandoned and as far as I can tell you need a PhD in autoconf to compile the latest version, Csope is alive and well.

Usacases

Csope shines at exploring stranger and obscure code bases due to its TUI. It sometimes gets mislabelled as a code navigation tool, but the original documentation describes it best as a "code browsing tool". Many tools can jump you to a definition or grep for patterns, but Csope is unique in that it allows for those and many other functionalities while providing you with a very comprehensible list of all results, ready to fire up your editor at just the spot. An example of its excellence is this project. The Cscope code-base used to be a total mess, fixing it would have been a lost cause, if not for Cscope itself. Well, Csope now.

Improvements/Changes

User side

  • Renamed the program, because "cscope" is annoying to type
  • Improved tui
  • GNU Readline/History integration

To the code

  • Nuked autoconf, replaced with single Makefile
  • Reorganized the control flow
  • Encapsulated various functionalities
  • Removed macro hell used for compiling on a dead badgers
  • Reduced global state hell
  • Use stdbool instead of YES/NO macros
  • Removed dead code
  • ...and much more

Installation

Gentoo

Add my overlay and install using portage.

From source

After you made sure you have the following installed:

  • ncurses
  • GNU Readline
  • GNU History (should come with Readline)
  • Lex (or GNU Flex)
  • Yacc (or GNU Bison)

Just run:

make

This will yield the executable "csope", which you are free to do whatever with.

Hint:

cp csope /usr/bin/

Quick start

Start browsing your project by running csope over it's source dir.

csope -s source/

Configuration

Readline

The readline integration should be complete -please let us know if not-, except for your prompt being used, which could easily break the TUIs display.

The rl_readline_name variable will be set to "Csope", so you may have conditional configurations in your .inputrc with the following format:

$if Csope
	# <whatever>
$endif

Colors

All can be configured sucklessly under "config/colors.h". Hopefully the comments are self evident.
