patch 9.0.1827: xxd: no color support
Problem: xxd: no color support
Solution: Add color support using xxd -R
Add some basic color support for xxd
The hex-value and value are both colored with the same color depending
on the hex-value, e.g.:
0x00 = white
0xff = blue
printable = green
non-printable = red
tabs and linebreaks = yellow
Each character needs 11 more bytes to contain color. (Same color in a
row could contain only one overhead but the logic how xxd creates colums
must be then changed.) Size of colored output is increased by factor of
~6. Also grepping the output will break when colors is used.
Flag for color is "-R", because less uses "-R".
Color uses parameters auto,always,never same as less and grep (among
others).
E.g.
xxd -R always $FILE | less -R
Add some screen-tests (that currently on work on linux) to verify the
feature works as expected.

.TH ccfilter 1 "01-Apr-97" .SH NAME ccfilter \- a compiler's output filter for vim quickfix .SH SYNOPSIS ccfilter [ .B <options> ] .SH DESCRIPTION The ccfilter utility "filters" the output of several compilers and makers (make/gmake) from several platforms (see NOTES below) to a standardized format which easily fits in vim's quickfix feature. For further details, see in vim ":help quickfix". .PP ccfilter reads .B 'stdin' and outputs to .B 'stdout' \. .PP The need for ccfilter is clear, as some compilers have irregular and/or multiple line error messages (with the relevant information on line 2), which makes it impossible for the errorformat to correctly display them ! When working on different platforms, and with different compilers, ccfilter eases the utilization of quickfix, due to its standardized output, allowing to have in .vimrc a plain .br .B \ \ \ \ :set\ errorformat=%f:%l:%c:%t:%m .SH USAGE When using ccfilter, one would include the following lines in .vimrc: .br .B \ \ \ \ :set shellpipe=\\\\|&ccfilter\\\\> .br .B \ \ \ \ :set errorformat=%f:%l:%c:%t:%m .SH OPTIONS .TP 16 -c Decrement column by one. This may be needed, depending on the compiler being used. .TP -r Decrement row by one. This may be needed, depending on the compiler being used. .TP -v Verbose (Outputs also invalid lines). This option makes ccfilter output also the lines that couldn't be correctly parsed. This is used mostly for ccfilter debugging. .TP -o <COMPILER> Treat input as <COMPILER>'s output. Even when configuring ccfilter to assume a default COMPILER, sometimes it's helpful to be able to specify the COMPILER used to generate ccfilter's input. For example, when cross-compiling on a network from a single machine. .TP -h Shows a brief help, describing the configured default COMPILER and the valid parameters for COMPILER. .SH NOTES Currently, ccfilter accepts output from several compilers, as described below: .TP 10 GCC GCC compiler .TP AIX AIX's C compiler .TP ATT AT&T/NCR's High Performance C Compiler .TP IRIX IRIX's MIPS/MIPSpro C compiler .TP SOLARIS SOLARIS's SparcWorks C compiler .TP HPUX HPUX's C compiler .SH AUTHOR .B ccfilter was developed by .B Pablo Ariel Kohan .BR .B mailto:pablo@memco.co.il
