# 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 changes to the TUI into display.c
+ Encapsulated searching into find.c
+ Removed "scanner.l" which seems to be an ancient version (and redundant copy) of "fscanner.l" forgotten by all
+ Removed macro hell put in place to allow compiling on a dead badger
+ Use stdbool instead of YES/NO macros
+ Saved kilobytes by stripping trailing whitespace
+ ...and much more
# Installation
You will have to compile 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.
# Future features / contributor wishlist
+ providing support for other languages by integrating new lexers (e.g. ctag's)
