NAME

cwe - (color wrapper) echo

SYNOPSIS

cwe [string]

DESCRIPTION

cwe is a command to echo special formatted (colored) strings to standard output. cwe is directly linked to the cw binary and cw recognizes that it is only designed to color a single string and exit. if you are not familiar with cw you should probably consult that documentation first. (as long as the first 3 letters are "cwe" in the link name, cw will assume it is cwe)

The main purpose of cwe's existence is to expand color to shell prompts, shell scripts, and other (non-program/file wrapping) things while still keeping (some of) the color scheme cw provides.

Several conversions are supported, and are the same as the print definition instruction when using cw directly.

\\
ignore the current \
\e
escape conversion, usually used for ANSI (color) codes
\r
carriage return conversion
\n
new line conversion
\t
horizontal tab conversion
\v
virtical tab conversion
\xNN
hexadecimal value conversion, must be followed by two bytes(00-ff) (where available)
\C[color]
color conversion, brackets are included in the string
the color values used are in the text form of:
black, blue, green, cyan, red, purple, brown, grey+, grey, blue+, green+, cyan+, red+, purple+, yellow, white, default, none, random, random+, random&
colors with a + designate a brighter color. random, random+ and random& are random colors set at the start of cw or by the CW_RANDOM environmental variable (random& is a complementary color to random and random+)

EXAMPLES

bash# export CW_RANDOM='cyan:blue'
bash# export PS1='$(cwe "\C[random+]\u\C[default]# ")'
(note that \u is processed by bash and not cwe)

ENVIRONMENT

CW_RANDOM
creates a new random colorset based on a list of colors separated by colons. the random color selected will be used for the colors random, random+ and random& (color values explicitly used in context to this variable are: black, blue, green, cyan, red, purple, brown, grey, grey+)
CW_NORANDOM
disables random colors by always using the first list choice (any value placed in the variable will enable)
CW_INVERT
re-defines the internal colormap to the opposite colors. this is intended to help terminals with white backgrounds become more readable (any value placed in the variable will enable)
CW_COLORIZE
defines a static colorset to override the definition file(and CW_INVERT) colors. this is intended to help make a uniform color scheme. the format is CW_COLORIZE=color[:color] ('[' and ']' are not included). if a second color is provided you may use any colors desired for both fields, however if you place just one color in the variable it must be one of the following colors: black, blue, green, cyan, red, purple, brown, grey, grey+, random (using the dual color entry style can cause irregular coloring using offbeat combinations do to the method being used to colorize, it is recommended to use the single entry style)
CW_REMAP
remaps one or more internal color(s) to ANSI values or other internal color values. this is useful for remapping colors to special ANSI (code) values or more advanced color scheming (than CW_COLORIZE). the colors random, random+, random&, default and none may not be remapped or used. the format is CW_REMAP=color=[##;##|color]:color=[##;##|color]:... ('#' stands for a single digit, which forms the ANSI code; '|' stands for "or", and the '|' is not included; '[' and ']' are not included)
CW_SUPERMAP
changes the internal color format to an entirely different color format(ie. non-ANSI), this is intended for special non-console coloring situations. supermaps are internal and can be listed by running cw -V. if a supermap and a remap are both defined, then the supermap will be forcefully disabled due to potential internal conflicts
