grep-terms - Print lines that match terms
This document describes version 0.006 of grep-terms (from Perl distribution App-GrepUtils), released on 2022-05-03.
% grep-terms [GREP-TERM-OPTIONS]... <TERMS> [GREP-OPTIONS | FILES]... % grep-terms --help % grep-terms --version|-V
Example:
% grep-terms "foo bar baz -qux -quux" -i file.txt
will print lines from file.txt that contain "foo", "bar", "baz" (in no particular order) and do not contain "qux" or "quux".
grep-terms is a simple wrapper for Unix command grep. It converts terms (the first argument) like this:
grep-terms
grep
"foo bar baz -qux -quux"
to:
-P -e '^(?=.*foo)(?=.*bar)(?=.*baz)(?!.*qux)(?!.*quux)'
It allows searching each term in terms in no particular order and negative search (using the dash prefix syntax). The drawback is that the pattern does not capture anything and thus does not highlight anything. To highlight terms, specify the "--highlight-terms" option which will add a second grep invocation to do highlighting.
0 on success.
255 on I/O error.
99 on command-line options error.
The following options are grep-terms' own option. All other unknown options will be passed to grep.
If set, will apply a second grep to highlight the terms, so:
% grep "foo bar baz -qux -quux" FILE1 FILE2
will become:
% grep -P -e '^(?=.*foo)(?=.*bar)(?=.*baz)(?!.*qux)(?!.*quux)' | grep --color=always -P 'foo|bar|baz'

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, and sometimes one or two other Dist::Zilla plugin and/or Pod::Weaver::Plugin. Any additional steps required beyond that are considered a bug and can be reported to me.
