Nodewatch for Productivity

November 4, 2013
tags:  leonodewatchpluginltdproductivitycode-dump

Recently, I contributed the nodewatch.py plugin to Leo. I wrote this as a way to keep myself productive, and have an at-a-glimpse look at important nodes in my workbook.leo file. I thought I'd share the @nodewatch definitions I hacked together to help with this.

Some important notes:

  1. The snippets below are on gist, which does not to my knowledge allow syntax highlighting without a file suffix. Ignore the .py in the filenames -- those are node headlines.
  2. These definitons require Terry Brown's todo.py plugin to be enabled, else they will throw exceptions and not work.
  3. These definitions use python-dateutil's relativedelta to make my life easier. You'll need to pip install python-dateutil to get these scripts to work.

Some preliminaries first. All four of the @nodewatch definitions I have below use the same << imports >> and get_tasks_by_date nodes as children. I used clones for this, to keep them all in sync. Here's << imports >>:

And here's get_tasks_by_date:

Alright... now, get_tasks_by_date() returns a list of vnodes that are not marked 'done' by todo.py, but have a duedate or nextworkdate such that comparator(date,otherdate) is True. That does all the hard work. Next up is 4 very similar @nodewatch definitions:

Putting this all together under your @settings node, and clicking the Refresh button (or running the command nodewatch-update), you now have 4 categories in your Nodewatch GUI's drop-down box: 'LTD: 00 Past Due', 'LTD: 01 Due Today', 'LTD: 02 Due Tomorrow', and 'LTD: 03 Due This Week'. This will help you get fast looks at what you need to focus on today, tomorrow, and this week.

Unfortunately, the get_tasks_by_date code is a bit ugly and really dense, and it required a read through of the todo.py source, and understanding of the operator module... but it packs a lot of filtering power into those lines, making other due-date sorting @nodewatch definitions easier in the future. For example, you could define a @nodewatch Due This Month script with:

Plenty of other things can be done with nodewatch, but this is my primary usage so far.
