This document describes version 0.003 of list-display-resolution-names (from Perl distribution App-DisplayResolutionUtils), released on 2016-10-12.
% list-display-resolution-names [options] [query]
*marks required options.
Set path to configuration file.
Can be specified multiple times.
Set configuration profile to use.
Do not use any configuration file.
Choose output format, e.g. json, text.
Set output format to json.
When outputing as JSON, strip result envelope.
By default, when outputing as JSON, the full enveloped result is returned, e.g.:
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:
- --help, -h, -?
Display help message and exit.
- --version, -v
Display program's version and exit.
This script has shell tab completion capability with support for several shells.
To activate bash completion for this script, put:
complete -C list-display-resolution-names list-display-resolution-names
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 shcompgen which allows you to activate completion scripts for several kinds of scripts on multiple shells. Some CPAN distributions (those that are built with Dist::Zilla::Plugin::GenShellCompletion) will even automatically enable shell completion for their included scripts (using
shcompgen) at installation time, so you can immadiately have tab completion.
To activate tcsh completion for this script, put:
complete list-display-resolution-names 'p/*/`list-display-resolution-names`/'
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
For fish and zsh, install
shcompgenas described above.
This script can read configuration files. Configuration files are in the format of IOD, which is basically INI with some extra features.
By default, these names are searched for configuration filenames (can be changed using
--config-path): ~/.config/list-display-resolution-names.conf, ~/list-display-resolution-names.conf, or /etc/list-display-resolution-names.conf.
All found files will be read and merged.
To disable searching for configuration files, pass
You can put multiple profiles in a single file by using section names like
[SOMESECTION profile=SOMENAME]. Those sections will only be read if you specify the matching
You can also put configuration for multiple programs inside a single file, and use filter
program=NAMEin section names, e.g.
[SOMESECTION program=NAME]. The section will then only be used when the reading program matches.
Finally, you can filter a section by environment variable using the filter
env=CONDITIONin section names. For example if you only want a section to be read if a certain environment variable is true:
[SOMESECTION env=SOMEVAR ...]. If you only want a section to be read when the value of an environment variable has value equals something:
[SOMESECTION env=HOSTNAME=blink ...]. If you only want a section to be read when the value of an environment variable does not equal something:
[SOMESECTION env=HOSTNAME!=blink ...]. If you only want a section to be read when an environment variable contains something:
[SOMESECTION env=HOSTNAME*=server ...]. Note that currently due to simplistic parsing, there must not be any whitespace in the value being compared because it marks the beginning of a new section filter or section name.
