NAME
Data::Sah::Filter::perl::Str::replace_map - Replace (map) some values with (to) other values
VERSION
This document describes version 0.025 of Data::Sah::Filter::perl::Str::replace_map (from Perl distribution Data-Sah-Filter), released on 2024-07-17.
SYNOPSIS
Using in Sah schema's prefilters
(or postfilters
) clause
[
"str"
,
"prefilters"
,[[
"Str::replace_map"
]]]
Using with Data::Sah:
my
$schema
= [
"str"
,
"prefilters"
,[[
"Str::replace_map"
]]];
my
$validator
= gen_validator(
$schema
);
if
(
$validator
->(
$some_data
)) {
'Valid!'
}
Using with Data::Sah:Filter directly:
my
$filter
= gen_filter([[
"Str::replace_map"
]]);
my
$filtered_value
=
$filter
->(
$some_data
);
Sample data and filtering results
"foo"
# filtered with args {map=>{baz=>"qux",foo=>"bar"}}, valid, becomes "bar"
"bar"
# filtered with args {map=>{baz=>"qux",foo=>"bar"}}, valid, unchanged
DESCRIPTION
This filter rule can be used to replace some (e.g. old) values to other (e.g. new) values. For example, with this rule:
[
replace_map
=> {
map
=> {
burma
=>
"myanmar"
,
siam
=>
"thailand"
}}]
then "indonesia" or "myanmar" will be unchanged, but "burma" will be changed to "myanmar" and "siam" will be changed to "thailand".

CONTRIBUTING
To contribute, you can send patches by email/via RT, or send pull requests on GitHub.
Most of the time, you don't need to build the distribution yourself. You can simply modify the code, then test via:
% prove -l
If you want to build the distribution (e.g. to try to install it locally on your system), you can install Dist::Zilla, Dist::Zilla::PluginBundle::Author::PERLANCAR, Pod::Weaver::PluginBundle::Author::PERLANCAR, and sometimes one or two other Dist::Zilla- and/or Pod::Weaver plugins. Any additional steps required beyond that are considered a bug and can be reported to me.
