colorize
========

Description
-----------
Colorize aims at being a small, independent and handy command-line
text colorizing tool.  It emits ANSI escape sequences in order to
color lines of text; also, sequences emitted by colorize or foreign
programs may be cleared.

The main code is written in C (c89 mostly), whereas the test script
consists of Perl code.

Colorize is known to build and test successfully on Linux and
Net/Open/MirBSD.  Other platforms are untested, so be prepared for
it to eventually not work as expected there.

Requirements
------------
gcc
make
perl
valgrind (optional)

Build instructions
------------------
Issue `make' to build colorize.

Once completed, run the tests with `make check'.

Then you should most likely have a working binary.

Next, install it with `make install' (may require elevated
user permissions).

Finally, clean up the working directory through `make clean'.

Customizing instructions
------------------------
The default character ('/') which separates the foreground
from the background color may be redefined:

`make FLAGS=-DCOLOR_SEP_CHAR_COLON' -> defines as ':'
`make FLAGS=-DCOLOR_SEP_CHAR_SLASH' -> defines as '/'

Debugging instructions
----------------------
For the sake of completeness, colorize can be also built with
debugging output by issuing `make FLAGS=-DDEBUG'.  The intention
is to provide some memory allocation diagnostics (and might be
extended in future).  Usually, a debugging build is not required.

Furthermore, tests can be run through valgrind by issuing, for
example, `make check_valgrind 2>&1 | tee valgrind.out'.  The
file provided here for the `tee' invocation will be populated
with the captured output from both standard output and error
stream.

Configuration File
------------------
A user configuration file may be populated with options and
according values.  See man page source file `colorize.1' for
details.

Documentation
-------------
See man page source file: colorize.1.

Usage example
-------------
In ~/.bashrc:

| ls_color() {
|     ls "$@" | colorize green -
| }
| alias ls=ls_color

This excerpt defines an alias which will set the color being
printed for literal ls invocations to green.

Afterword
---------
Let me know, if you have ideas, bug reports, patches, etc.
