Complete::Sah - Sah-related completion routines


This document describes version 0.013 of Complete::Sah (from Perl distribution Complete-Sah), released on 2023-05-26.


 use Complete::Sah qw(complete_from_schema);
 my $res = complete_from_schema(word => 'a', schema=>[str => {in=>[qw/apple apricot banana/]}]);
 # -> {words=>['apple', 'apricot'], static=>0}




 complete_from_schema(%args) -> any

Complete a value from schema.

Employ some heuristics to complete a value from Sah schema. For example, if schema is [str => in => [qw/new open resolved rejected/]], then we can complete from the in clause. Or for something like [int => between => [1, 20]] we can complete using values from 1 to 20.

Tip: If you want to give summary for each entry in in clause, you can use the attribute, example:

 # schema
 ['str', {
     in => ['b', 'g'],
     '' => ['Male/boy', 'Female/girl'],

This function is not exported by default, but exportable.

Arguments ('*' denotes required arguments):

  • schema* => str|array

    Will be normalized, unless when schema_is_normalized is set to true, in which case schema must already be normalized.

  • schema_is_normalized => bool (default: 0)

    (No description)

  • word* => str (default: "")

    (No description)

Return value: (any)

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.
