hours

This program offers a budgeting algorithm, along with a use case for budgeting time.

The budget algorithm, currently located in Hours.Budget and Hours.Calc, is time agnostic, and simply takes two lists of intervals -- a set of ideal periods, and a set of real periods -- and computes various statistics about where you are now, where you should be, and if you're on track. This code could be used for budgeting any resource, really, but I use it right now for tracking time.

Three programs are built along with this library:

• work-periods: Computes the current ideal work periods relative to the current time, as expected by my employer. I don't expect anyone else to use this program, but you might copy and modify the to suit your environment.

• utimelog-periods: Converts a file in the Emacs timeclock format, which is just simply i DATE TIME for clock-in, and o DATE TIME for clock-out (and which can also be understood by Ledger) into a set of real intervals.

  I use the program org2tc to convert my Org-mode file with clocking information into a timeclock log, in order to feed into this timelog-periods program.

• process-hours: Given an ideal set of intervals, and a real set of intervals -- and specifically intervals whose ranges are marked by time, and whose associated values are "time expected/actually worked during that period" -- this program computes the statistics and reports them in an Emacs Lisp format, so they can be read and reported using the included jobhours.el file.

  Note that if you want to build a budgeting program around monetary values, or gallons of gas, or water rationing, etc., this program would need to change, as well as the programs you use to generate the ideal and real data (assuming you don't create it by hand, since it's just JSON).

The final result of all this is a very brief indicator in my Emacs window that looks something like this:

6.2h | 8.4

This means that I have 6.2 hours left to work today to "stay on track", and that my current progress will require me to work 8.4 hours every interval (usually a work day) for the remaining intervals of this work period. The upright bar means I'm currently in a "work day", and the color of the display indicates whether I'm falling behind (starts becoming red), or getting ahead (starts becoming green).

This way, within a moment's glance, I know the following details:

1. How much I should work today before kicking off.
2. Whether I'm on track towards the end of the period.
3. If I'm starting create long nights for myself in the near future.
4. How close I am to overall completion (the background of the begins to fill as work intervals are finish, until it's fully colored).
