Adding a how-to

To add a how-to to this page add a heading under the correct category OR create a category if one doesn't exist. There are currently no formatting or style rules. The suggestion is to be clean and well laid out. Look over the current how-to's to get a feel on how your tutorial should be laid out. Thank you for the contribution.

On some page choose the edit option.  
Step 2
Create a link to the page you want to created. Ex.

Applying a patch to a Repo


Step 1 

Download the .patch or .diff file onto your machine

Step 2 

Navigate to the repo that you want to install the patch to i.e. testRepo 
(I will using repo name for this example, substitute it with your repo name when you are trying to apply a patch yourself)

Step 3 

Open testRepo\.hg\hgrc (the config file)

Step 4 

Add the following to hgrc and save (This enables queues for hg so that we can use commands that we need, qimport and qpush)[extensions]
hgext.mq =

Step 5 

Now open up a command prompt and navigate to your repo directory

Step 6 

Type in hg qimport <<full-path-of-patch-file>> and press enter

Step 7 

The above command should create a patch folder within testRepo\.hg\patches\

Step 8 

Next navigate to  testRepo\.hg\patches\

Step 9 

Type in hg qpush <<patch-file-name>>

Step 10 

Done! The patch should have been applied (if you get an error such as “abort: local changes found, 
refresh first” then that means you have made changes to the original files and the patch won’t work)
