NAME App::column::run - Run several commands and show their output in multiple columns VERSION This document describes version 0.005 of App::column::run (from Perl distribution App-column-run), released on 2021-07-08. DESCRIPTION Sample screenshots: FUNCTIONS column_run Usage: column_run(%args) -> [$status_code, $reason, $payload, \%result_meta] Run several commands and show their output in multiple columns. This utility is similar to using the Unix utility pr to columnate output, something like (in bash): % pr -T -m -w $COLUMNS <(command1 args...) <(command2 args...) except with the following differences: * commands are run in sequence, not in parallel (although parallel execution is a TODO list item); * all output are collected first, then displayed (although streaming output is a TODO list item); * multiplexing STDIN to all commands; * ANSI color and wide character handling; * passing adjusted COLUMNS environment to commands so they can adjust output; * passing common arguments and environment variables to all commands (as well as allowing each command to have its unique arguments or environment variables). This function is not exported. Arguments ('*' denotes required arguments): * args_arrays => *array[aos]* Arguments to give to each command (an array of arrays of strings). If "--common-args" is also set, then the common arguments will be added first, then the per-command arguments. * commands* => *array[str]* * common_args => *array[str]* Common arguments to pass to each command. If "--args-arrays" is also set, then the common arguments will be added first, then the per-command arguments. * common_envs => *hash* Common environment variables to pass to each command. * envs_arrays => *array[hos]* Environment variables to give to each command (an array of hashes of strings). * linum_width => *posint* Line number width. * on_long_line => *str* (default: "clip") What to do to long lines. * separator => *str* (default: "|") Separator character between columns. * show_linum => *bool* Show line number. Returns an enveloped result (an array). First element ($status_code) is an integer containing HTTP-like status code (200 means OK, 4xx caller error, 5xx function error). Second element ($reason) is a string containing error message, or something like "OK" if status is 200. Third element ($payload) is the actual result, but usually not present when enveloped result is an error response ($status_code is not 2xx). Fourth element (%result_meta) is called result metadata and is optional, a hash that contains extra information, much like how HTTP response headers provide additional metadata.
