NAME

Data::Sah::FilterJS - Generate filter code

VERSION

This document describes version 0.021 of Data::Sah::FilterJS (from Perl distribution Data-Sah-Filter), released on 2023-06-21.

SYNOPSIS

 use Data::Sah::FilterJS qw(gen_filter);

 # use as you would use Data::Sah::Filter

DESCRIPTION

This module is just like Data::Sah::Filter except that it uses JavaScript filter rule modules.

VARIABLES

$Log_Filter_Code => bool (default: from ENV or 0)

If set to true, will log the generated filter code (currently using Log::ger at trace level). To see the log message, e.g. to the screen, you can use something like:

 % TRACE=1 perl -MLog::ger::LevelFromEnv -MLog::ger::Output=Screen \
     -MData::Sah::FilterJS=gen_filter -E'my $c = gen_filter(...)'

FUNCTIONS

gen_filter

Usage:

 gen_filter(%args) -> any

Generate filter code.

This is mostly for testing. Normally the filter rules will be used from Data::Sah.

This function is not exported by default, but exportable.

Arguments ('*' denotes required arguments):

  • filter_names* => array[str]

    (No description)

  • return_type => str (default: "val")

    (No description)

Return value: (any)

ENVIRONMENT

LOG_SAH_FILTER_CODE => bool

Set default for $Log_Filter_Code.

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.
