Lawrencium is a Mercurial wrapper for Vim, inspired by Tim Pope's Fugitive.
The recommended method to install Lawrencium is to use Pathogen, also from Tim Pope:
cd ~/.vim/bundle
hg clone https://bitbucket.org/ludovicchabant/vim-lawrencium
You can then update the help tags with :call pathogen#helptags() and browse Lawrencium's help pages with :help lawrencium.
Open a file from one of your Mercurial repositories.
:e ~/Work/Project1/src/foo.py
Work on it for a bit, then open another file, this time using Hgedit and a
repository-relative path:
:Hgedit src/bar.py
Take advantage of the auto-completion when typing the path! Work on that other file too, then compare it to the parent revision version:
:Hgvdiff
Continue working. At any moment, you can run a Mercurial command and get a quick glance at its output:
:Hg log --limit 5 src/blah/bleh
Note how auto-completion will help you with all the built-in commands and their options! Any other parameter will auto-complete with repository-relative paths.
Once you're happy with your work, bring up the status window:
:Hgstatus
You can see the difference between modified files and their parent revision
version easily by moving the cursor to the appropriate line and hitting
Ctrl-V. You can also do an addremove by using Ctrl-A (use the selection mode
to add/remove several files at once!).
Now it's time to commit. While still in the status window, remove all mentions
of files you don't want to commit, and hit Ctrl-S. Write your commit message,
go :wq, and you're done! You can check everything went fine:
:Hg tip
You can also commit faster with the :Hgcommit command of course!
And that's it for now. Open the help file with :help lawrencium, and post
your questions and problems in the issue tracker on BitBucket.
