From time to time a user asks for Subversion support in TextMate, and recently I saw a comment on the Rails blog asking for it as well.
So just a note to mention that TextMate already has pretty good out-of-the-box Subversion support, and a short tutorial about how to generate ssh key pairs to avoid having to type passwords when you login over ssh.
You’ll need to checkout your files from the terminal, but after that you can press ⌃⇧A to get the following menu (with Subversion actions) for the current file, or in case of Add to Repository and Commit, actions for the selected items in the project drawer.
Two things it currently doesn’t do is:
- Indicate the status of a file. I plan to add the proper API so that plug-ins can provide this.
- Request password if you use subversion over ssh. The solution to this is to generate an ssh key pair and upload the public key to the server, so that you can connect to the server w/o having to enter password.
To generate an ssh key pair you’ll need to run the following line in your terminal:
ssh-keygen -t dsa
It’ll ask for location and pass phrase, and you should accept the default location (
~/.ssh/id_dsa.pub) and press return when it asks for pass phrase (to give the private key a blank pass phrase).
After this you need to upload the public key to the server. For this we use
email@example.com with your user and server name (by default the user name is your local user):
scp ~/.ssh/id_dsa.pub firstname.lastname@example.org:
Finally login to the server and append the public key to authorized keys:
ssh email@example.com mkdir .ssh # if it's not already there cat id_dsa.pub >>.ssh/authorized_keys rm id_dsa.pub # cleanup
After this, you should be able to login to the server and use
scp without having to enter a password.
If you do login or copy files to your server a lot, you can setup an alias. This is done by editing
~/.ssh/config (on your local machine). For example I have this entry in that file:
Host mm HostName macromates.com User ceo
This defines a new host (named
mm) which expands to
macromates.com and with
ceo as the default user. What this allows me to do is copy files like this:
scp some_image.png mm:www/images
ssh mm ls www/images
The first example copies
some_image.png from my local folder to the
www/images folder on the server. The second example logs into the server, executes an
ls www/images, and gives me back the result.
For more info about the ssh configuration file run
And just for the records, my user isn’t named
ceo, I made that up to avoid my real user (i.e. email address) to be harvested.
