There is a strong desire in our group to move towards distributed version control systems specifically mercurial. As I spend most of my time working on the Chemistry Add-in for Word 2007 (Chem4Word) I have been using Visual Studio 2008. This doesn’t come with source control support out of the box – but you can (and we have) added on team foundation server support but this isn’t distributed and quite frankly sucked.
I have spent the last couple of days investigating other options and having got a good solution up and running thought I should share this with the world. This definitely isn’t meant to be an introduction to mercurial in general and I won’t be explaining all the terms (good intros are available from the mercurial website and elsewhere). I will be giving both command line and GUI instructions.
Next make VisualHG the current active Source Control Plugin in Visual Studio 2008. <Tools> -> <Options> -> <Source Control>. Set the value of the drop-down list (Current Source Control plug-in) to <VisualHG>.
How to create a new repository and add it to source control
Open Visual Studio 2008 and create a new solution (in my case I went for a Console Application called
C:\projects\c# and I didn’t want a new directory for the solution)
In a command window change directory so you are in
this will create the
create a file called
.hgignore as a sibling of the
.hg directory the contents of the file should be:
Create a project on bitbucket with the same name as the solution (doesn’t have to be but will make things easier). So in this case I now have a publicly viewable repository on bitbucket
Now create a file called
hgrc under the
.hg directory. This file should contain the following text:
default = http://bitbucket.org/jat45/cs-walkthrough
username = Joe Townsend
jat45 should be replaced with your bitbucket id and
cs-walkthrough should be replaced by the name of the bitbucket repository you just created.
From here on in you can do everything either from the command line or from within Visual Studio. I will give both commands (to access the VisualHG commands right-click on any of the files in the solution). All the command line commands should be run from the
<HG status> from VisualHG
We want all these files under source control so either use
or select all the files from the GUI and click
Add then close the window
To commit these additions either use
>hg commit -m "initial commit"
or commit using
Now push these changes to bitbucket
<HG Synchronize>(this will allow you to push, pull and see the incoming and outgoing changes).
Before committing or pushing changes you must make sure you build the solution first. This ensures that the
[project].csproj file is correctly updated.
Getting an existing project
This is much easier than creating a new repository from scratch. Once again though we are back to the command line.
Change directory to the parent of where you would like the new project repository to be checked out to. In my case this is
I am now going to get a clone of the cs-walkthough code from bitbucket but put it in a new location.
c:\projects\c#>hg clone http://bitbucket.org/jat45/cs-walkthrough my-new-source-dir
You can use the same command because the project is public so you can access the source code but not commit.
So I think that is it. You can do all the usual, push, pull, diff and so on either from the command line or from the VisualHG add-in. The one only thing that must be done from the command line is the initial
init. I am also investigating if everything works in VS2010 – so far no problems but if I run into any I will update you.
