NAME

show-color-swatch - List all color names from a Graphics::ColorNames scheme as a color swatch

VERSION

This document describes version 0.008 of show-color-swatch (from Perl distribution App-GraphicsColorNamesUtils), released on 2023-12-05.

SYNOPSIS

show-color-swatch --help (or -h, -?)

show-color-swatch --version (or -v)

show-color-swatch [--columns=posint|-c=posint] [--format-options=s] [--format=name|--json] [--(no)naked-res] [--row-height=posint] [--table-width=posint|-w=posint] -- <scheme>

OPTIONS

* marks required options.

Main options

--columns=s, -c

Default value:

1
--row-height=s

Default value:

3
--scheme=s*

(No description)

Can also be specified as the 1st command-line argument.

--table-width=s, -w

Default value:

80

Output options

--format-options=s

Pass options to formatter.

--format=s

Choose output format, e.g. json, text.

Default value:

undef

Output can be displayed in multiple formats, and a suitable default format is chosen depending on the application and/or whether output destination is interactive terminal (i.e. whether output is piped). This option specifically chooses an output format.

--json

Equivalent to --format=json-pretty.

--naked-res

When outputing as JSON, strip result envelope.

Default value:

0

By default, when outputing as JSON, the full enveloped result is returned, e.g.:

[200,"OK",[1,2,3],{"func.extra"=>4}]

The reason is so you can get the status (1st element), status message (2nd element) as well as result metadata/extra result (4th element) instead of just the result (3rd element). However, sometimes you want just the result, e.g. when you want to pipe the result for more post-processing. In this case you can use --naked-res so you just get:

[1,2,3]

Other options

--help, -h, -?

Display help message and exit.

--version, -v

Display program's version and exit.

COMPLETION

This script has shell tab completion capability with support for several shells.

bash

To activate bash completion for this script, put:

complete -C show-color-swatch show-color-swatch

in your bash startup (e.g. ~/.bashrc). Your next shell session will then recognize tab completion for the command. Or, you can also directly execute the line above in your shell to activate immediately.

It is recommended, however, that you install modules using cpanm-shcompgen which can activate shell completion for scripts immediately.

tcsh

To activate tcsh completion for this script, put:

complete show-color-swatch 'p/*/`show-color-swatch`/'

in your tcsh startup (e.g. ~/.tcshrc). Your next shell session will then recognize tab completion for the command. Or, you can also directly execute the line above in your shell to activate immediately.

It is also recommended to install shcompgen (see above).

other shells

For fish and zsh, install shcompgen as described above.

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.
