Tracking Your Toggl Timer With Tmux-powerline

I’ve recently started using Toggl to track time spent on various things. But I usually forget to turn it on when I’m actually working.

I wrote a little script that uses Node.JS to get my active running timer on Toggl and display it on my tmux-powerline. It displays nothing if no timer is running.

The script can be found here:

Do remember to chmod +x the JS file and include it as a segment in your status bar.

Using Custom Attributes in Markdown Links

This blog runs on Octopress — which means that I write posts in Markdown.

I’m presently a big fan of Microformats and wanted to include rel="me" links to other websites that I use.

After searching a little for a clean solution, I realised that Markdown is HTML-compatible - I can simply write in the exact HTML I need for the link within my Markdown file.


Instead of writing something like


and then trying to add custom attributes; I can simply write

<a href="" rel="me">@adhipg</a>.

Obviously you can use this for any other custom attributes/html you want.

Ugly - yes. But it works and does not need JavaScript.

Creating Sub-repositories From Your Git Repository

So you have a nice big project that you’ve been working on for a while and you are at a state where you think it will be nice to split a part of the project. This can be to either create it as a library to use it with other projects or just maintain it independantly.

There are two steps involved:

  • Splitting out the subpath from the repository and creating a new repository from it.
  • Using this new git repository we’ve created in the main repository so that we can continue working.

Let’s tackle them one at a time.

Splitting a subpath into a new repository

I’m assuming that we’re interested in keeping the git history - else, you can simply just copy out the directory into a new folder and init it as a new repository.

Using git filter-branch

git filter-branch --prune=empty --subdirectory-filter my-api -- --all

The -- --all is to ensure that we filter all the branches in the repository.

Next, you simply add new remotes and push your repository there.

git remote add my-new-remote
git push --all

Side note: You’ll have to clone the original repository again.

Using git subtree

git subtree is a new git command that recently was added into git. Using it to create the new repository is simple enough:

git subtree split --prefix my-api --branch my-api-repo

Now the my-api-repo branch consists of just the contents from my-api and all the relevant commits. This can now be used to push to a new remote:

git push split:master

Merging the subpath back into the original repository

We use git subtree from earlier for this.

git subtree add --prefix my-api --squash master

The --squash here implies that we just want to create a merge commit - else, we’ll end up with duplicate commits in the history.
