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'.
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.
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.
