ot - parse text and (hopefully) open an editor with the correct arguments


version 0.000005


    ot "lib/Foo/Bar.pm line 222"
    # Executes $ENV{EDITOR} +222 lib/Foo/Bar.pm

    # open Foo::Bar which is in your lib, t/lib or @INC
    ot Foo::Bar

    # open Foo::Bar at the do_something() subroutine
    ot "Foo::Bar::do_something()"

    # open output from git-grep
    ot lib/Open/This.pm:17

    # Find a core module
    ot Test::More

    # Open a core module at a function
    ot "Test::More::diag()"


It can be a pain to have to copy Perl module names from a stack trace or some other output and have to translate that into something which an editor like vim understands. This module aims to take some of the pain out of this. So far I have tested this only with vim, but I *think* this should also work with emacs and nano.

The ot script can parse line numbers from text so that you can open your files at the correct starting point. It will also try to translate subroutine names into the appropriate line numbers. It will look in a lib or t/lib directory relative to your current path. If it thinks it has a Perl module name it will also try to require it and use %INC in order to find the module on disks. All security caveats apply when requiring 3rd party modules.


By default, ot will search your lib and t/lib directories for local files. You can override this via the $ENV{OPEN_THIS_LIBS} variable. It accepts a comma-separated list of libs.

    export OPEN_THIS_LIBS=lib,t/lib,t/other-lib


    OPEN_THIS_LIBS=lib,t/lib,t/other-lib ot Foo::Bar

Probably you want to export this variable in your ~/.bashrc file (or some other appropriate place in your dot files.
