Todo.txt task tracking

Probably due to the simplicity of the task tracking solution, I was drawn into contributing many fixes, enhancements, Wiki edits and quick answers on the mailing list, all of which were greatly appreciated by the community. Enabled by the script's extension points, I initially developed, modified and used 24 small addon scripts to customize the application to my workflow, before publishing them as a separate project (see below).

The great GitHub platform, existence of an automated test suite, and friendly community of partially less technical people made contributing so much fun. My first steps consisted of cleanup of help messages, code consistency and minor bug fixes, in order to learn more about the script and the community. Later I contributed enhancements and then coordinated problem reports and fixes from other developers. This resulted in the v2.7 release on 04-Aug-2010, where I contributed 39 out of 42 commits, and continued with me as the lead developer of the v2.8 release on 14-Sep-2011.


From the beginning, I had picked up some Todo.txt add-ons from various contributors, and soon wrote my own custom commands, configuration, and special filters. This eventually culminated in a set of matching interdependent extensions that codified my personal approach to task handling. Because there had been keen interest in various pieces of my add-ons, I finally released them as a separate project in Feb-2012.

Vim text editor

I'm an avid user of the Vim text editor since Vim 6.0 in 2002.

Since Dec-2006, I'm a member of the mailing list, where I participate in troubleshooting help, feature discussions, and strategy. I've submitted several bug reports and Vim patches, many of which have been incorporated into the mainline.


Since Dec-2007, I partipate in the Vim Tips Wiki, amassing 104 edits as of Mar-2012. I also frequent the Vim subreddit, and watch questions tagged Vim on Stack Overflow, answering questions as they come up.


Starting Sep-2006, I have published several of my customizations and enhancements as Vim scripts on the community site. Some of them have been downloaded over a thousand times. I'm one of the most prolific script authors, with 90+ published plugins (up from 38 in March-2012). I have been contributing bug reports, patches, and critiques to at least as many plugins by other authors (to some of them regularly as a kind of co-development), and regularly receive (overwhelmingly positive) feedback about them.

list of contributions

Here's an incomplete list of my contributions to the open source community; many minor things have been omitted:


Jun-2014 Stack Overflow community
After three years on Stack Overflow, I've gained 59k reputation and 8/28/58 gold/silver/bronze badges. My accepted answer percentage rate is at 51%, significantly more than the average of 39%!
Apr-2014 Adoption of personal Vim plugin fork
I got a pull request on my extended fork of an (apparently unmaintained) Vim plugin, informing me that the developer had taken my modifications and extended those. Out of that friendly exchange arose a couple of mutual extensions.


Dec-2013 Stack Overflow community
After 20 months, I've gained 40k reputation and 6/20/42 gold/silver/bronze badges.
This was a rather calm year; I've mostly answered issues and reviewed all incoming pull requests, which was acknowledged in the 2.10 release announcement.
Todo.txt extensions
I added and improved several actions in what I would call controlled evolution. The suite of add-ons around the Todo list (with currently 600 entries) still form the base of my task management.
Vim plugins
I'm continuously tweaking my personal configuration, adding useful commands and mappings. This year, a lot of inspiration came from questions on Stack Overflow. By giving back (answers and help), I learn and gain a lot (inspiration, ideas to do things differently), too!
Due to my heavy use and extensive automated test suite for my plugins, I was able to report several issues and got most of them quickly fixed by friendly colleagues. In particular, I found several corner case inconsistencies in the new Vim 7.4 NFA-based regexp engine, resulting in patches 7.4a.032 and 7.4a.039.


Dec-2012 Stack Overflow community
After 8 months of following and answering Vim questions on Stack Overflow, I've gained 13k reputation and my first two gold badges for reviewing 1,000 edits and casting 600 votes.
03-Feb-2012 Todo.txt extensions
In addition to a couple of add-ons to Todo.txt provided by other users, I wrote my own customizations: Add-on scripts to adapt the versatile command-line application to my own workflow by introducing shortcuts as well as totally new functionality, and more highlighting for additional syntax that I've invented. Since other users apparently faced similar issues and questions are coming up regularly on the mailing list, I've added a test suite for my add-ons and published my extensions as a separate GitHub project. With this, I can now simply refer such questions to my implementation.


22-Nov-2011 I18N for nowrap / vim_dev
Reported a small issue within the Cygwin terminal to the author, and offered advice on how to make his tool work with <Tab> and double-width characters. Shortly thereafter, a similar discussion came up on the vim_dev mailing list, where I educated the OP about the differences of character widths, number of characters, and bytes to represent the character in a particular encoding.
18-Oct-2011 CamelCaseMotion fork
Noticed through a blog article about Vim plugins that I found through that someone named bkad had created a private fork of my plugin, fixed a small bug, but hadn't sent this to me. I contacted the author just as he was discussing with a collaborator how to contribute back the changes.
14-Sep-2011 Todo.txt
New official release v2.8 that where almost the entire functionality was provided by me. I got a big thank-you for pushing the project forward in the release message.
30-Jul-2011 vcscommand.vim
Contributed three patches to this popular Vim plugin. As I have done more invasive enhancements that I so far use privately (and intend to contribute back), I soon decided to use Git instead of my home-grown writebackup to maintain my modifications in separate branches. This turned out to be so beneficial that I will use GitHub clones for all future contributions to Vim plugins.
29-Mar-2011 Vim
Found out by chance (while browsing other people's public .vimrc configurations) that someone named Lokaltog had used the logic from my StatusLineHighlight plugin for a similar purpose, and has credited me in the comments.


04-Aug-2010 Todo.txt
New official release v2.7 that contains my cleanup of help and error messages, many small bugfixes, several improved commands, and highlighting of done tasks. Overall, I committed 39 out of 42 changesets.
25-May-2010 Todo.txt
Found a couple of inconsistencies and nuisances while adopting this simple script for task tracking. Submitted a set of bug fixes and enhancements (together with accompanying automated tests) via GitHub, which were pulled into upstream a mere four hours later.

Continued Vim script which was abandoned by its original author. Added many bugfixes and modernized the main algorithm.

10-Mar-2007 writebackup
After years of helpful use, published first of the many little helper scripts that I am continually developing and tweaking in order to become more efficient. Had to decide on a license and delivery strategy. Most of my scripts were too small to warrant the formalism of Sourceforge, and GitHub hadn't been invented yet, so I put them into a download area on my website.
