I have updated the Capistrano local subversion module and added a perforce one.
The original article is here.
I have added rsync as an option to speed up
the deployment to remote servers, To use that option install this
version,
in the example below I have installed the file into my rails projects
lib/tasks directory.
When the rsync option is set the deployment method will use rsync over
ssh to synchronize between a local cache of the subversion project and
a remote cache, minimizing the amount of data uploaded to the server.
To use rsync use this in the deploy.rb...
require 'lib/tasks/local_subversion_rsync.rb'
set :scm, Capistrano::SCM::LocalSubversionRsync
set :repository_is_not_reachable_from_remote, true
set :use_rsync, true
set :local_rsync_cache, "/home/user/projects/aproject/cache"
set :remote_rsync_cache, "/var/www/webapp/cache"
set :rsync_username, "ausername"
set :rsync_excludes, ["*.bak", "*.log"]
The rsync_username and rsync_excludes are optional.
The :rsync_username option sets the username that ssh uses to login
to use rsync. Leave it blank if it is the same as your current login
name.
The :rsync_excludes option allows you to pass --exclude options to
rsync, using the rsync syntax for exclusions, this is an array of
patterns to exclude.
Note you must do a local SVN checkout to the directory specified by
local_rsync_cache at least once before using this method.
Also the directory specified by remote_rsync_cache must exist on the server.
The perforce version of the scm module that allows the perforce server
to be accessed locally only is
here,
note that this does not currently support the rsync option
or write to the revisions.log.

UPDATE 2007-06-09 This method has been deprecated in Cap 2.0.
UPDATE 2007-02-21 I have updated the files to correctly update revisions.log
UPDATE I added rsync as suggested see end of article for more info.
I previously published a custom deploy recipe that allowed subversion
to checkout from a local repository and send to the remote server.
This was a suboptimal solution, as it wouldn't work with things like
deprec.
So here is the way I should have done it in the first place. It is a
modified version of the standard subversion scm module, it should be
backward compatible with the built in version, but adds a couple of
features.
- Handles the subversion repository only being accessible from the local
machine
- If the subversion repository is accessible from the remote server
allows for different URLs for access from the local and remote
machines.
If you use a standard deploy.rb and your subversion is accessible
from the server, then it should work exactly as the built-in version
(no need to use it then, but it should work)
However if you have your subversion server behind your local firewall,
you just add these three lines to your deploy.rb
require 'lib/tasks/local_subversion_rsync.rb'
set :scm, Capistrano::SCM::LocalSubversionRsync
set :repository_is_not_reachable_from_remote, true
And everything will work as before, even though the server has no idea
what subversion is.
Of course for this to work you need to download
this de-tar
it and put it in your lib/tasks directory. (That's where the require
line gets this extension from). There is also a unit test for the
new_subversion module which is extended from the one shipped with
Capistrano, which passes.
Everything else in deploy.rb should be the same as before, except
that you set the repository to the URL your local machine uses to
access your locally accessible subversion server or repository.
(Should even work with the URL file://...), for instance...
set :repository, "svn://your.svnserver.host/#{application}/trunk"
The assumption is that both the local and remote machines can create
files and directories in /tmp, if this is not true then one or both
of these should be set...
set :tmpdir_local, "/usr/tmp"
set :tmpdir_remote, "/home/user/tmp"
The way this module works is to export the relevant version of the
project from Subversion into a temporary directory on the local
machine (default is /tmp/unique_name). Then I create a gzip'd tar
archive into the temp directory. The tar file is then transferred to
the target servers, using the Capistrano put command into a
temporary directory (/tmp by default) on the server. I then create the
target directory on the server and un-tar the file into that
directory. Then clean up the various temporary files. From the
perspective of the server the end result should be identical to doing
an svn export into the target directory on the server.
The other facility this SCM Module provides is when your subversion
server is accessible from the server as is the "normal" use case (per
the Capistrano developers, but bad practice IMHO), but you need a
different URL to access the SVN repository from the local machine vs
the remote server, eg
server accesses with this URL svn://localhost/myapp/trunk
local machine accesses with this URL svn+ssh://myserver.com/myapp/trunk
in this case you add these lines...
require 'lib/tasks/local_subversion_rsync.rb'
set :scm, Capistrano::SCM::LocalSubversionRsync
set :local_repository_path, "svn+ssh://myserver.com/myapp/trunk"
set :repository, "svn://localhost/myapp/trunk"
In addition if the actual SVN binary is different on server and local
you can add these for instance...
set :remote_svn, "/usr/local/bin/svn"
set :local_svn, "/usr/bin/svn"
If the relevant configuration variable is not set then the standard
svn configuration variable is used, and then just "svn" if that is not set.
Please beware I have not fully tested the use cases other than the
first one, where I use my local subversion server to deploy to my
remote servers that know nothing about subversion, however the unit
tests do pass for the other use cases.
UPDATE 2007-02-15 check this article for using the rsync option.

I've just started a new RoR project and thought I'd try out
HAML for the views instead of rhtml.
Seeing as I just switched to JEdit, I looked for a HAML language mode,
and to my surprise no one had done one yet.
So here is my first attempt at a language mode for JEdit and version
1.0 of the HAML language mode. It needs more work, and I hope someone
with a better understanding of JEdit language modes will help out.
This will set the indent to 2 spaces and auto-indent after a %tag that
has nothing else on the line...
%p
stuff
It will not auto indent if there is more stuff on the line like in the
following example the line after %p gets indented but the line
after %label does not.
%p
%label{ :for => "login" }Login
%br/
= f.text_field :login
I have setup a basic syntax coloring scheme that should color %tags
and .classes and #ids differently. It will color anything
following an = or ~ and defer the syntax highlighting to the ruby
mode for anything following them, ditto for anything inside { }.
Feedback and better ideas are welcome.
Download from here
To install copy the file to ~/.jedit/modes, and edit the catalog file
in that directory and add this line:
<MODE NAME="haml" FILE="haml.xml" FILE_NAME_GLOB="*.haml" />
Then restart jedit, and your haml files will be syntax highlighted.
I like HAML but there simply is not enough example code out there
yet, so here are two simple conversions from well know rhtml files
into HAML...
First the standard login form from acts_as_authenticated
- form_tag sessions_path do
%p
%label{ :for => "login"} Login
%br/
= text_field_tag 'login'
%p
%label{ :for => "password" }Password
%br/
= password_field_tag 'password'
%p
%label{ :for => "remember_me" }Remember me:
= check_box_tag 'remember_me'
%p
= submit_tag 'Log in'
Next the new user form from the same place...
= error_messages_for :user
- form_for :user, :url => users_path do |f|
%p
%label{ :for => "login" }Login
%br/
= f.text_field :login
%p
%label{ :for => "email" }Email
%br/
= f.text_field :email
%p
%label{ :for => "password" }Password
%br/
= f.password_field :password
%p
%label{ :for => "password_confirmation" } Confirm Password
%br/
= f.password_field :password_confirmation
%p
= submit_tag 'Sign up'
If this is dumb HAML coding please let me know how to improve it :)

I imported the rest of the Textmate ruby and rails snippets I had to combine them
into the one ruby file though.
I have added about 80 new ones to the existing ones by Scott Becker
that I found here
The list of snippets I now have is at the end of this post, note I did change the
abbreviation for some of the assertions they all now start with as so
I can search for them faster with my select_superabbrevs macro
described in the previous post.
download the new snippets from here
unzip and replace the ruby file in the .jedit/SuperAbbrevs directory with the one in
this zip archive.
You need the Beta version of SuperAbbrevs to use this from here
