# Csope
Fork of Cscope version 15.9, with various improvements, because cscope is good and shall not be forgotten.
While the original's mainentence 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 obsecure code bases due to its TUI.
It sometimes gets mislabeled 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 unqie in that it allows for those and many other functionalities while providing you with a very comprehansible list of all results,
ready to fire up your editor at just the spot.
An example of its excelence is this project. The Cscope codebase 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 anchient 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 (dev) libraries installed:

	ncurses
	GNU Readline
	GNU History (should come with Readline)

Just run:

	make

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

Hint:

	cp csope /usr/bin/

# Configuration
## Readline
The readline integratoin 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)
