Tidy a file inline
Perltidy is a nifty prettifier or pretty printer as it was called back in the day. I always forget the inline option.
perltidy --nostandard-output --warning-output --backup-and-modify-in-place myperlfile.pl
Do note that the inline modification does not take place if you input are from:
- standard in
- going to standard out
- or the
--htmlflag is provided
From the documentation:
A -b flag will be ignored if input is from standard input or goes to standard output, or if the -html flag is set.
Use the specify the --nostandard-output and work on files.
The short form is:
perltidy -nst -w -b myperlfile.pl
Using a Profile
You can specify your own Perl::Tidy configuration, if you are not using the default configuration
perltidy --nostandard-output --warning-output --backup-and-modify-in-place --pro=t/perltidyrc myperlfile.pl
And the short form:
perltidy -nst -w -b --pro=t/perltidyrc myperlfile.pl
Using perltidy in a pre-commit hook
You can use perltidy in a pre-commit hook.
I recommend the pre-commit framework and the existing hooks.
Please see my TIL: use pre-commit.
