Make Github issue numbers appear in browser tabs

#70. Yippee!

#70. Yippee!

I use Github Issues as a bugtracker for a number of my projects. My workflow usually includes having the ticket open in one browser tab, and a local WordPress installation open in another browser tab (to test the bugfixes themselves). When I write commit messages, I want to reference the issue number, but by default, it’s buried deep in the <title> element, and thus not visible on a smallish browser tab.

So I wrote a short userscript that reproduces the issue number at the beginning of the <title>, so I can see it at a glance. It’s structured as a userscript for Greasemonkey/Firefox, though I imagine you could easily repackage it for Chrome or whatever.

[code language=javascript]
// ==UserScript==
// @name github issue number in tab
// @namespace https://boone.gorg.es
// @description github issue number in tab
// @include https://github.com/*/*/issues/*
// @version 1
// @grant none
// ==/UserScript==

var t, ttext, issueno;

t = document.getElementsByTagName( ‘title’ );
ttext = t[0].innerHTML;
ino = ttext.match(/Issue #([0-9]+)/);
console.log(“#” + ino[1] + ” ” + ttext);
t[0].innerHTML = “#” + ino[1] + ” ” + ttext;
[/code]

Anthologize campaign update, and a sneak peek

My Anthologize development fundraiser is going great so far – as of this writing, $870 has been pledged. Put that together with the generous match from CHNM, and you’ve got $1,740. This translates to over 23 hours of dev time. A huge thanks to those who have already made pledges – you’ll be hearing from me individually once the campaign is over on October 10.

Aside from some miscellaneous cleanup and compatibility issues, my first goal during the development period will be to get the plugin running better in more server environments. Our most reported bug is that Anthologize Exports time out due to memory limits. This is an especially vexing problem on inexpensive, shared hosting, which is what much of the Anthologize target audience uses for hosting their WordPress sites. I’ve started to sketch out a plan in this Github ticket for making Anthologize exports less memory-hungry.

It’s always hard to estimate these things, but I’m guessing that 23 hours will be enough to do the initial plugin cleanup, and to get most of the way toward the rewrite of the export process described above. That’s progress!

Remember, more pledges mean more development. If you want to see more fixes and enhancements to Anthologize, you’ve got until October 10 to donate.

Musings on Git and Github

About a year and a half ago, I started moving all my personal and professional software development to Git and Github. Here are a few thoughts on what it’s meant for me as a developer.

Originally, the primary impetus for the change was that, as version control software, Git is so much better than Subversion. But in the last few months, the value of Github (the site, as opposed to Git the software) has become increasingly evident and important. As developers (in the WordPress world, especially) have taken more and more to Git, and as folks in general have become more familiar with Github, the value of Github’s social model to my work has increased by a huge amount. Between private and public repositories, client work and open source projects, I collaborate with dozens more people today than I did at this time last year. Some of this collaboration is planned ahead of time, and so maybe isn’t so notable. But increasingly, it’s unexpected and unsolicited – forked repos, pull requests, bug reports and patches.

Probably many of these changes are incidental, and are unrelated to version control at all. But I like to think that the mechanisms of Git – cheap branching, sophisticated merging – and the design of Github – activity streams, easy forking – have played a role. Using Github has changed, and continues to change, my development practices, by making me think more about audience and reuse (notions that are familiar to teachers of writing), encouraging the “release early and often” mantra (since all my stuff is public anyway more or less as soon as I write it), and orienting me toward collaboration by default, rather than solo coding. All these changes are highly laudable, leading to better product, and making my work more fun.

If you are an open-source developer, working in locked-up or practically invisible repositories (or, heaven forbid, not under version control at all), do yourself a favor and get acquainted with Git and Github. The benefits are potentially transformative to the way you approach your work.

Anthologize 0.6

I just tagged version 0.6-alpha of Anthologize in the wordpress.org plugin repo. This new version has a bunch of bug fixes, improvements to stability and consistency of output, and a few new feature goodies. Read more about the release here.

On a related note, Anthologize development has recently moved 100% over to our Github repo. We’d previously used Trac for ticketing and Github for code management, but now we’re doing everything on Github. If you’re a user, please feel free to open new issues. If you’re a developer, send those pull requests!

Working on a photoblog theme for WordPress

After seeing that Andrew Spittle is working on a WordPress theme for a mobile photoblog (as discussed here), I thought I’d do the same. I happen to like Autofocus pretty well, so I’ve just made a child theme, with a few Twitter-specific modifications. Follow it on Github: https://github.com/boonebgorges/boones-photoblog. (Keep in mind, you’ll need the parent theme Autofocus installed for the Boone’s Photoblog theme to work.)

Revisiting Git, Github, and the wordpress.org plugin repository

Some months ago, I wrote about using Git and Github with the wordpress.org plugin repository. Since that time, I’ve been refining my plugin development workflow. I now do all of my development with Git, using git-svn tools to do all svn management.


Preamble: Git as primary vs secondary

Before talking more about my workflow, I should make a sort of conceptual distinction. When I develop most of my plugins, I am working alone. In these cases, Git is primary. It’s where the meaningful version control happens, while svn.wp-plugins.org is just a gateway for wordpress.org/extend, the distribution channel. I am not using the wordpress.org svn repository for version control or code sharing in any interesting way. Likewise with a few team projects that I’m involved in, notably Anthologize. All of our code-sharing and true version control happens via Git and Github (here’s our repo), with the wordpress.org svn repo used only as a distribution mechanism.

In contrast, I also use Git to develop BuddyPress, but the strategy is quite different. In the case of BuddyPress (as in the case of WordPress), the svn repo is the officially sanctioned version control system for the project. Git, in this case, is a secondary, local versioning system – essentially, my development sandbox. This setup places additional restrictions on how the git-svn link is managed, raising issues such as juggling svn branches, tagging version off of an svn branch, exporting patches in an svn-compatible format, and so on.

In this post, I’ll be focusing on the first kind of development setup, in which the wordpress.org svn repo is serving merely as a distribution channel. It’s a bit simpler to start there. Moreover, I’ve been chatting with Mark Jaquith about Git for WP development, and I know from those chats that he’s planning on writing up a description of the second kind of workflow (which characterizes the WordPress core work that he’s more concerned with). So I’ll leave the sophisticated stuff to him.


Part One: Getting your repos set up

You’ll need to have Git installed on your computer, with git-svn compiled. Here’s a guide to compiling it yourself on OS X; it’s also available through a number of repos on various OSes.

Create a directory for the plugin in the plugins directory of your dev install. I’ll use my recently released plugin Unconfirmed as an example; you can follow along using the example (until it comes time to push and commit!), or use your own plugin.

[code]

cd wp-content/plugins

mkdir unconfirmed

[/code]

The next step will require you to clone your wordpress.org svn repo. This assumes that you have requested and been granted space in the repository already. If you’re just starting plugin development and don’t want to request space yet, that’s OK – just begin your development in a normal Git repository. As long as you are pushing your Git changes somewhere (like Github), you’ll be able to wipe out your local copy when it comes time to send it to wordpress.org and start from this point as if you were starting from scratch.

Get a revision number for the plugin. You don’t want to force git-svn to crawl through the 300,000+ revisions on the wordpress.org repository. (For those keeping score, this is the only time you will have to run an svn-native command!)

[code]

svn log http://plugins.svn.wordpress.org/unconfirmed

[/code]

Look for the first commit number, where the plugin was added to the repository. In my case, it’s r387893.

[code]

r387893 | plugin-master | 2011-05-23 04:10:19 -0400 (Mon, 23 May 2011) | 1 line

adding unconfirmed by boonebgorges

[/code]

Clone the svn repository into the local plugin directory. Here’s the syntax, followed by some explanation.

[code]

git svn clone -t tags -b branches -T trunk -r387893 http://plugins.svn.wordpress.org/unconfirmed unconfirmed

[/code]

  • git svn clone is the command itself
  • -t tags -b branches -T trunk tells Git about the directory structure of the svn repository that you’re cloning. The flag --stdlayout or -s is shorthand for the same thing, though I’ve had mixed luck getting it to work – so I just enter the whole thing explicitly.
  • -r387893 is the svn revision number where I want Git to clone. In the next step, we’re going to tell Git to fetch the svn revision history starting with this commit; that’s why we chose the first, rather than the last, commit from the unconfirmed repo.
  • http://plugins.svn.wordpress.org/unconfirmed is the address of the plugin on the wordpress.org repo. It’s important to use this address rather than the alias http://svn.wp-plugins.org. As I discovered (after much frustration), Git is not able to trace the branch/tag history from the wp-plugins.org address – you have to use plugins.svn.wordpress.org.
  • unconfirmed is the relative path to the directory where I want the repo cloned.

Next, fetch the svn commit history like so:

[code]
cd unconfirmed
git svn fetch
[/code]

When you hit enter, git-svn queries the wordpress.org repo, starting with the initial revision number you pegged in the previous step, and walks all the way forward to the (entire) repo’s most recent revision, mirroring your plugin’s svn revision history in your local Git clone. If you’ve just received the space in the svn repo, this will only take a few seconds. If you’re doing this with a plugin that was put into the repo some time ago, or one that has a lot of revisions (and branches and tags) in the svn repo, you’ll have to wait a long time. Drink a beer or ten while you wait.

You’ll know the process is done when you are returned to your command prompt. Test to make sure that you’ve pulled in all of the remote tree by entering the following:

[code]
git branch -r
[/code]

This will show you a list of all the remote branches being tracked by this Git repository. If it’s a fresh repo, you’ll only see the trunk. If it’s a repo with existing branch and tag history, you’ll see one Git branch corresponding to the trunk, one corresponding to each svn tag, and one corresponding to each svn branch.

If you’re not planning to use Github or to share your code with anyone else, you’re done. If you are planning to use Github (as I do), you’ll need to add your Github endpoint as a remote repository. Assuming you’ve already created a repo on Github,

[code]
git remote add origin git@github.com:boonebgorges/unconfirmed.git
[/code]

origin is the name I’ve chosed for the Github endpoint, but you can call it whatever you want.

Now it’s time to reconcile your commit histories. Hopefully, you’ve only got one history to deal with – either in the Git or in the svn repo – so you won’t have too much trouble. In such a situation, something like the following should work:

[code]
git pull –rebase origin master
[/code]

So, here’s the thing about --rebase. It rolls back, albeit temporarily, all of the changes on your local copy of the repository back to the last common commit, applies all of the remote revisions, and then attempts to apply your revisions on top of it. If you are working with a fresh Github repository, there will be no common commit in the history, and there won’t be any revisions from Git to rebase back onto the tree. Thus, the svn history will be rolled back, zero commits will be put onto the local repo, and the svn history will be laid back down. In other words, nothing will happen, except that the Github repository will establish a common ancestor revision, allowing you to push. Mutatis mutandis, if you have an active Github repo but an empty svn repo, zero commits will be rolled back, and your Github history laid on top of the local repo, with the zero commits laid back on top. In other words, it’ll sync with the Github history seamlessly, and allow you to commit back to the svn repo by establishing a common revision history. If you have active, separate commit histories in both svn and Github, may God have mercy on your soul.

In any case, use --rebase with great caution. Read the git-rebase docs and try to wrap your head around it before doing anything that will mess up the revision history.

Once you’ve successfully pulled from Github, your three repositories – the local Git repo, the Github Git repo, and the svn repo on wordpress.org – will all be aware of each other and in sync. You are ready to develop.


Part Two: Day to day development

Let’s say you’ve found a bug (OH NOES) and you need to fix it. Before digging into the code, get yourself to the command line to make sure you’re in good working condition.

The first thing I do before I touch any code is to see what’s happening in my local repo:

[code]
git status
[/code]

There’s a lot of good information that git status can give you, for which I refer you to the docs or to Google. The important concept for our purposes is that we start a new local branch every time we want to fix a bug or develop a new feature. The notion of hyper-specific, temporary branches is one of Git’s biggest selling points, as well as one of the places where it differs the most from the way that many WP developers work with svn. Since branches are strictly local unless explicity pushed, and since Git’s merge and rebase tools are so nice, you can create, merge, and destroy branches at will, and keep your work separate. To add (and switch to) a branch called stupidbugfix, use this syntax:

[code]
git checkout -b stupidbugfix
[/code]

This does two things: it creates the new branch stupidbugfix, and it checks out that branch (similar to svn switch). git status will show you that you are now On branch stupidbugfix.

Do your bugfixing as you would normally do. When you’re ready to commit the changes, do another git status. You might see a result that looks like this:

[code]
# On branch stupidbugfix
# Changed but not updated:
# (use “git add …” to update what will be committed)
# (use “git checkout — …” to discard changes in working directory)
#
# modified: readme.txt
#
no changes added to commit (use “git add” and/or “git commit -a”)
[/code]

In this case, I’ve made changes to one file: readme.txt. In order to commit these changes, you’ll first need to stage the file with git add:

[code]
git add readme.txt
[/code]

(git add is automatically recursive, so you can add whole directories this way too.) Now you can commit the changes:

[code]
git commit -m “Fixing that stupid bug.”
[/code]

If you’re confident that you want to stage all changed files to a commit, you can skip the explicit git add and use the -a flag:

[code]
git commit -am “Fixing that stupid bug”
[/code]

Now, let’s get your changes from the stupidbugfix branch into the master branch, which we’ll use to push to our central repository. Then we’ll delete the temporary stupidbugfix branch.

[code]
git checkout master
git merge stupidbugfix
git branch -d stupidbugfix
[/code]

If you are sharing your code on Github, you can push your commits at this point:

[code]
git push origin master
[/code]


Part Three: Releasing a new version to the wordpress.org repo

If you’re following the steps I’ve outlined above, all of your development is happening in Git and Github. The only time you’ll need to touch the wordpress.org repository is when you want to release a new version. Here is the procedure I use. [EDIT 2012-09-14: See the Addendum below for an improved workflow for this step.] First, rebase the svn trunk to your current branch.

[code]
git rebase trunk
[/code]

This small bit is crucial, and it took me many months of frustration before I finally stumbled upon this (cache only!) blog post, which put me on the right track. The concept here – so far as I understand it, at least – is that git-svn actually rewrites the MD5 hash that Git uses to identify the changeset, and when you rebase the trunk into your current local branch, you forcing git-svn to match Git-changeset MD5s with svn-changeset MD5s. If you don’t do this, you’ll get infinite merge conflicts.

Now, let’s send those commits to wordpress.org svn.

[code]
git svn dcommit
[/code]

This sends all changesets (since the last time you dcommitted) up to the WordPress svn repository. (In other words, you’re mirroring the revision history.) Once this is done, the revision history on your svn trunk will match that of your current git branch.

Now we’re ready to tag the release in svn. (I’m assuming that you’ve already changed current version and stable tag numbers in your plugin files before dcommitting. If not, make those changes, git commit them, git rebase trunk, and git svn dcommit.)

[code]
git svn tag 1.1
[/code]

This will do the same thing as when you svn cp your trunk into tags/1.1.

I like to keep tag history in Git as well. Git tags are metadata (while svn tags are really just branches), so they have to be created separately, and pushed up to Github.

[code]
git tag -a 1.1 -m “Tagging 1.1”
git push –tags
[/code]

Finally, before making any more changes that can be pushed back to Github, you’ll have to rebase from Github – again, to make sure that Git understands that your Git MD5s have been overwritten by git-svn. Assuming you’re on your master branch:

[code]
git pull –rebase origin master
git push origin master
[/code]

Again, this rebase business is scary and dangerous, so try to understand the possible ramifications if you are working on projects that involve other people.


Conclusion

This might seem like a lot to learn. But developing in Git is hugely beneficial, well worth the learning curve. Git’s agile branching allows a kind of focused, compartmentalized development strategy that can’t easily be replicated with svn. And having Github as a bugtracker and changeset-viewer is also really great. Plus, working with Git in my own development means that I don’t have to code-switch (pardon the pun) when working with clients who use Git for collaborative work, which, I’m finding, is increasingly common. Learning about Git with your own WP plugins is a great way to learn some of the finer points of Git.


Addendum (14 Sep 2012): Be a better wordpress.org citizen and squash

The biggest headache in the git/wordpress.org workflow has always been lining up the revision histories. Git revision histories are non-linear, and SVN does not understand them. So the process of rebasing the development branch into the trunk-tracking branch is always precarious, as trunk is a flattened, svn-friendly branch. Moreover, even when the rebase does work, you end up reduplicating revision histories in both Git and SVN, when the real purpose of wordpress.org SVN here is really just distribution. (This makes Otto sad.)

So, for the last six months or so, I’ve used a modified version of the release workflow described in Part Three. First, I have a local branch, which I call svn, which tracks trunk:

[code]
git checkout -b svn trunk
[/code]

At release time, I check out the svn branch, and do a squash merge. This means that all changes since the last commit to the svn branch are laid on top of svn as if they were a single set of changes. You can then commit these changes as a single changeset (thus keepin’ it linear, and keepin’ it short for Otto’s sake):

[code]
git checkout svn # if you’re not already on it
git merge –squash master
git commit -m “Merging changes from Git for 1.1 release”

[/code]

Note that you might get a message from Git that there were merge conflicts, in which case you’ll need to use mergetool to clean up. But this is a subject for another post.

Then, do your git svn dcommit and git svn tag from the svn branch. It’s important that you never rebase to or from the svn branch, or do any development there; all changes on that branch should be squash-merged from a git-only dev branch.

Project Reclaim

Update: I have begun aggregating these posts at projectreclaim.net.

Lately I have been feeling increasingly uneasy about the state of my digital affairs. I am a leader on a number of open source software projects that pride themselves on, among other things, their ability to enable users to “own their own data”. Moreover, I am trained as a philosopher, and have spent a pretty fair amount of time reading and thinking carefully about the nature of data and our relationships with it. If anyone is in a position to develop and advocate for good models of digital independence, I am.

Yet, when I look around my digital world, I see instance after instance where I am, to a greater or lesser extent, completely reliant on the good will of commercial entities and their propietary systems. To wit:

  • My Twitter account is a big part of my online identity
  • The last five years of my private correspondence, personal and professional, is in Gmail
  • I use Dropbox for syncing documents between devices (like my blog_sandbox.txt file, where I’m writing this post!)
  • I use Picasa Web Albums to back up and share photos
  • I have a Mozy account to back up the rest of my important files
  • Until recently, I had an iPhone. I still use a Mac
  • I use Remember The Milk for task management
  • I store source code for all my projects in Github

Some of these are products; some are services. Some are free; some of them I pay for. And – for sure – some of the companies behind the products and services listed above are more evil than others. So I don’t want to pretend that my reliance on each of them is equally bad. But each item on this list plays a crucial role in my digital life, and each one of them operates in a way that is beyond my control, both literally (I can’t modify the source code) and more figuratively (questions about ownership, exportability, transportability are icky).

I’m planning to extricate myself.

Project Reclaim

In order to make it sound a bit fancier, I’m giving my project a name: Project Reclaim. ‘Reclaim’ because it’s a manifestation of my desire to fight the inertia that leads us to give up control over our computing experiences, my desire to reclaim control and ownership. ‘Project’ because this will be hard, and ongoing. And why give it a name at all? I’m hoping that, by being public about it – putting my experiences in a series of blog posts and tweets under a common tag – that I’ll be able to hold myself accountable, and hopefully guide others who are hoping to reclaim their lives a bit as well.

In short, Project Reclaim is the process of weaning oneself off of digital platforms that are closed source and/or under the control of others.

Methodology

How will Project Reclaim actually work?

  1. Assess the situation I’ll first need a way of figuring out which systems and platforms are worth moving away from, what their replacements should be, and in what order I should effect the transition. I’ve got a few rules of thumb.
    • Open source is better than closed source. I write open-source software for a living. I believe that, on balance, it makes better software. And I believe that using software where one has access to the source code is a necessary component of maximizing one’s digital autonomy. Thus: if the third-party system I’m currently using is also a benefactor of open-source communities (like, say, wordpress.com), it makes it less urgent to move away. And, when selecting replacements, select open source if at all possible.
    • Paying is better than getting something for free This might seem like a contrast to the previous rule, but I don’t think it is. When you use a free service, somebody’s paying the bills. Usually that means targeted advertising – think Facebook and Gmail. Paying service fees, on the other hand, and agreeing to the contract that comes with it, generally has the effect of making the relationship more transparent. Of course, this is far from absolute, but it seems reasonable in a broad sense. Plus, I like to support developers and services that are truly valuable.
    • Go for the low-hanging fruit In cases like email, there are well-established, straightforward (though not necessarily easy…ugh) ways of fending for yourself. No need to invent the wheel. On the other hand, some of the areas where alternatives are less obvious – social networking-type data springs to mind – also happen to be areas where I have some expertise and leverage. So, in those cases, it might be worth innovating.
    • Get the important stuff first My email history is more important to me than my Twitter history; the convenience of Github is more valuable to me than the convenience of Dropbox. Plan the Reclaim accordingly.
    • Get the vulnerable stuff first Recent statements by Twitter have made me think that the way I interact with the services is more subject to change in the upcoming months than, say, the way I interact with Gmail. That’s frightening. The more profit-hungry the company is – and, thus, the more disinclined to have the customer’s freedoms in mind – the more urgent it is to pull yourself out.

    Clearly, some of these considerations are at odds with each other. But they give a rough framework for deciding whether, when, and how to carry out the mission of Project Reclaim.

  2. Make the switch Here’s where the action happens: I do what I need to do to move myself to the replacement.
  3. Write about it This weekend I spent an afternoon on the problem of Twitter, and I ran into a ton of technical problems that remain unresolved. I imagine that there will be similar hurdles for each part of the project. I’m hoping that, by writing about the problems (and, where they exist, the solutions) I can help other people to take some of the same steps themselves, or even to spur someone really smart to come up with better solutions than the ones that currently exist.

What I expect from myself

My goal, ultimately, is to move away from third-party, closed-source services and platforms altogether. It might take some time. So I’ll make some interim goals: by the end of 2011, I’m hoping to have my email moved, my microblogging federated, my own backup system on my own server space, and my computer running an open-source OS.

Even if I manage to meet this goal, there’s a very real sense in which Project Reclaim will necessarily be an exercise in futility. I’ll always have to buy server space, and who’s to say that Amazon or Slicehost won’t go berserk tomorrow? I’ll always have to connect to the internet, which leaves me perpetually at the mercy of the ISPs, who are IMO more evil than all of the other service providers put together. It’s a depressing state of affairs: the kind of autonomy I want might be impossible given the way that the economy works. I take some solace in the fact that philosophers have spilled much ink over the problem of free will without coming up with a clear formulation of exactly what kind of autonomy would be worth arguing for. At least I’m not alone in my delusion.

That said, it’s a fight that I feel I have a responsibility to fight. If I’m going to continue to argue for the use and development of open source software, I have to start putting my money where my mouth is. And so, to me, Project Reclaim is less about my being a paragon of virtue, and more about my wanting to sleep a bit better at night.

Do I think that everyone should do this? People should prefer open solutions to closed ones, all things being equal. But generally, all things are not equal. Most people don’t have the time to write their own software, to run their own servers. For those people, decisions about their digital life are (rightly, I think) made more on the basis of aesthetics and convenience than lofty concepts like Autonomy and Ownership. But there are a few considerations that are perhaps relevant for the kinds of people who read my blog:

  • Open source developers who tout the importance of data ownership and other such freedoms have a special responsibility to model best behavior in these areas.
  • Academics, more than anyone, should be sensitive to the dangers of leaving the crucial pieces of one’s online self in the hands of corporate entities. That’s true for personal artifacts like email, but perhaps doubly so for scholarly work that ought to be part of a public trust.
  • Educators, like open source developers, should model best practices, encouraging students to take control over their digital identities.

So, while I wouldn’t belabor the point for the average Joe, I do think that people who consider themselves members of one of these groups – as most people reading my blog probably do – that they should think carefully about their relationship with the tools and services that enable their digital existence.

To freedom!

Using Github with wordpress.org plugin SVN

Like this tutorial? Check out my updated and more comprehensive Git/Github/wordpress.org tutorial at https://teleogistic.net/2011/05/revisiting-git-github-and-the-wordpress-org-plugin-repository/.

I’m on a never-ending quest to come up with a good local environment that will support the kind of WordPress plugin development that I enjoy So Very Much. I’ve only just recently begun using Github for version control and already I can’t imagine living without it. But doing WP plugin development in Github is not totally straightforward, because wordpress.org’s plugin repository uses SVN. When it comes time to release a new version on the wordpress.org repo, it’s simply not practical to merge changes manually and manage two different version histories. I wanted a setup where I could use Github for everyday development, but would connect to WP SVN when I was ready to release.

There are lots of posts out there on how to use git-svn:

I couldn’t get any of the methods to work the way I wanted. But by mashing a few of them together, I have what is, I think, a workable setup. Here are the steps.

  1. If you don’t already have one, create a Github repository for your work. I’ll assume here that you have configured Git on your machine, with git-svn installed as well.
  2. Create a directory for your working copy. I use several local WP installations for plugin development, the main one of which is named Doris. So I’d do the following, for an imaginary plugin I’ll call awesome-plugin:
    [bash]
    cd /sites/doris/wp-content/plugins
    mkdir awesome-plugin
    [/bash]
  3. Before connecting to WP SVN, it’s a good idea to check for the revision number of your most recent commit. If you don’t, git-svn will sift through all 280,000+ revisions on svn.wp-plugins.org.
    [bash]
    svn log http://svn.wp-plugins.org/awesome-plugin
    [/bash]
    Scroll to find the most recent reversion number. Let’s say that in this case it’s r287228.
  4. Clone the svn repository to your newly created directory. Because I want this working copy to actually work as a WordPress plugin, I’m not going to check out the entire awesome-plugin tree. Instead, I’ll just get the trunk, and when I want to tag new versions of the plugin, I’ll do it in a separate working copy on my machine. (This is perhaps not the ideal way to work, but for me it works – probably irrationally, I like having “clean” instances of the trees somewhere on my machine that are used only for tagging new versions.)
    [bash]
    git svn clone http://svn.wp-plugins.org/awesome-plugin/trunk awesome-plugin -r287228
    [/bash]
    git svn clone will create the git-svn link and then do the initial fetch into the awesome-plugin directory.
  5. Depending on how you’re planning to use Git, you might want to create a branch that tracks the svn trunk, just for stable svn releases:
    [bash]
    cd awesome-plugin
    git checkout -b svn remotes/git-svn
    [/bash]
  6. Now that we’ve connected Git to WP SVN, we can connect to Github:
    [bash]
    git remote add -f origin git@github.com:boonebgorges/awesome-plugin.git
    [/bash]
    I’m calling Github ‘origin’ because I’m so used to push and pulling to and from ‘origin’, but you can call it whatever you want. Of course, make sure to change ‘boonebgorges/awesome-plugin.git’ to reflect your username and repo name.
  7. Let’s test the connections. If your Github repo is empty, you can push stuff up right away:
    [bash]
    git push origin svn
    [/bash]
    Remember that I am working on a branch called ‘svn’; you might use ‘master’ or something else altogether if you’d prefer. If your Github repo already had some files in it, you might find that you have to pull and merge them before pushing. Now make a change to your local:
    [bash]
    touch test.txt
    nano test.txt # Type something in the document and save it
    git add .
    git commit -m "testing git-svn"
    git push origin svn
    [/bash]
  8. Finally, let’s test to make sure that we can commit to SVN.
    [bash]
    git svn dcommit
    [/bash]
    The first time you try this, you will be prompted for your wordpress.org password. If your local username is not the same as your wordpress.org username (mine isn’t), just hit enter and SVN will ask for your full creds. You should get a “Committing to…” message, followed by “Committed r123456” or something along those lines. You can check to see that your commit has gone through by visiting http://svn.wp-plugins.org/awesome-plugin/trunk in your browser.

Good luck!
