NAME
App::Greple::stripe - Greple zebra stripe module
SYNOPSIS
greple -Mstripe [ module options -- ] ...VERSION
Version 1.00
DESCRIPTION
App::Greple::stripe is a module for greple to show matched text in zebra striping fashion.
The following command matches two consecutive lines.
greple -E '(.+\n){1,2}' --face +E
However, each matched block is colored by the same color, so it is not clear where the block breaks. One way is to explicitly display the blocks using the --blockend option.
greple -E '(.+\n){1,2}' --face +E --blockend=--
Using the stripe module, blocks matching the same pattern are colored with different colors of the similar color series.
greple -Mstripe -E '(.+\n){1,2}' --face +E
By default, two color series are prepared. Thus, when multiple patterns are searched, an even-numbered pattern and an odd-numbered pattern are assigned different color series.
greple -Mstripe -E '.*[02468]$' -E '.*[13579]$' --need=1
When multiple patterns are specified as in the above example, only lines matching all patterns will be output. So the --need=1 option is required to relax this condition.
If you want to use different color series for three or more patterns, specify step count when calling the module. The number of series can be increased up to 6.
greple -Mstripe::set=step=3 --need=1 -E p1 -E p2 -E p3 ...
MODULE OPTIONS
There are options specific to the stripe module. They can be specified either at the time of module declaration or as options following the module declaration and ending with --.
The following two commands have exactly the same effect.
greple -Mstripe=set=step=3
greple -Mstripe --step=3 --- -Mstripe::set=step=n
- --step=n
-
Set the step count to n.
- -Mstripe::set=darkmode
- --darkmode
-
Use dark background colors.
Use
--faceoption to set foreground color for all colormap. The following command sets the foreground color to white and fills the entire line with the background color.greple -Mstripe --darkmode -- --face +WE
