# NAME
App::Greple::stripe - Greple zebra stripe module
# SYNOPSIS
greple -Mstripe [ module options -- ] ...
# VERSION
Version 0.99
# 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. When multiple patterns
are specified, only lines matching all patterns will be output, so the
`--need=1` option is required to relax this condition.
greple -Mstripe -E '.*[02468]$' -E '.*[13579]$' --need=1
If you want to use three series with three patterns, specify `step`
when calling the module.
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 --
- **-Mstep::set**=**step**=_n_
- **--step**=_n_
Set the step count to _n_.
