# Csope
Fork of Cscope, 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 gui	/*pending*/
+ GNU Readline integration (ie. VI/EMACS mode, command history) /*pending*/
## To the code
+ nuked autoconf, replaced with single Makefile
+ removed "scanner.l" which seems to be an anchient version (and redundant copy) of "fscanner.l" forgotten by all
+ encapsulated changes to the TUI into display.c
+ removed macro hell put in place to allow compiling on a dead badger
+ replaced repeated inline #ifdef KEY_\*-s with guaranteed definitions
+ removed random commets giving tips for and refering to specific issues
+ use stdbool instead of YES/NO macros
+ saved kilobytes by stripping trailing whitespace
+ FILE\* refsfound used to be rewind()-ed everytime the reads were not sequencial

# Project structure	/*probably move to documentation*/
| Component | Purpose |
| :-------: | :-----: |
| main.c | generic init functions, main() and primary event loops (and junk)
| display.c | all functions directly dealing with NCurses |
| input.c | top layer of functions dealing with user input; migth dispatch to readline |
| globals.h | an inherited curse; global var/prototype hell |
| readline.c | all functions directly dealing with GNU Readline; responsible for line editing in *input mode* |
| help.c | all functions dealing with help messages |

# Future features / contributor wishlist
+ providing support for other languages by integrating new lexers (e.g. ctag's)
