NAME

Open::This - Try to Do the Right Thing when opening files

VERSION

version 0.000002

DESCRIPTION

This module powers the ot command line script, which tries to do the right thing when opening a file. Imagine your $EDITOR %ENV var is set to vim. (This should also work for emacs and nano.

ot Foo::Bar # vim lib/Foo/Bar.pm
ot Foo::Bar # vim t/lib/Foo/Bar.pm

Imagine this module has a sub called do_something at line 55.

ot "Foo::Bar::do_something()" # vim +55 lib/Foo/Bar.pm

Or, when copy/pasting from a stack trace:

ot "Foo::Bar line 36" # vim +36 lib/Foo/Bar.pm

Copy/pasting a git-grep result:

ot "Foo/Bar.pm:99" # vim +99 Foo/Bar.pm

FUNCTIONS

parse_text

Given a scalar value, this function will try to extract useful information from it. Returns a hashref on success. Returns undef on failure. file_name is the only hash key which is guaranteed to be in the hash.

use Open::This qw( parse_text );
my $parsed = parse_text('t/lib/Foo/Bar.pm:32');

# $parsed = { file_name => 't/lib/Foo/Bar.pm', line_number => 32, }

my $with_sub_name = parse_text( 'Foo::Bar::do_something()' );

# $with_sub_name = {
#     file_name   => 't/lib/Foo/Bar.pm',
#     line_number => 3,
#     sub_name    => 'do_something',
# };

to_editor_args

Given a scalar value, this calls parse_text() and returns an array of values which can be passed at the command line to an editor.

my @args = to_editor_args('Foo::Bar::do_something()');
# @args = ( '+3', 't/lib/Foo/Bar.pm' );
