| This program defines a run_all function which will retrieve two | |
| URLs and run a shell subcommand, all concurrently, using asyncio. | |
| What stands out in this example is the readability of the get() and cmd() | |
| functions, and the usefulness of asyncio.gather(). | |
| An excerpt from the program output shows the way they are interleaved: | |
| Start: http://google.com |
Locate the section for your github remote in the .git/config file. It looks like this:
[remote "origin"]
fetch = +refs/heads/*:refs/remotes/origin/*
url = git@github.com:joyent/node.git
Now add the line fetch = +refs/pull/*/head:refs/remotes/origin/pr/* to this section. Obviously, change the github url to match your project's URL. It ends up looking like this:
| #!/bin/bash | |
| # bash generate random alphanumeric string | |
| # | |
| # bash generate random 32 character alphanumeric string (upper and lowercase) and | |
| NEW_UUID=$(cat /dev/urandom | tr -dc 'a-zA-Z0-9' | fold -w 32 | head -n 1) | |
| # bash generate random 32 character alphanumeric string (lowercase only) | |
| cat /dev/urandom | tr -dc 'a-z0-9' | fold -w 32 | head -n 1 |
