esrcviz - Gource visualization of ESRC tend/sow history

Input is a csv file provided. This script will translate that csv into a log file that Gource can parse and visualize. This tool was used in the production of this video.

Input format sample:

InitialSeedDate,ActivityDate,EntryType,System,Pilot,class,regionName,age
1/1/2001,10/18/2019 21:21,tender,J000004,pilot1,C5,E-R00006,2
1/1/2001,10/18/2019 21:25,tender,J000003,pilot1,C6,F-R00003,3
1/1/2001,10/18/2019 21:32,tender,J000002,pilot2,C4,D-R00006,2
1/1/2001,10/18/2019 21:32,tender,J000001,pilot3,C2,B-R00003,37
1/1/2001,10/21/2019 7:18,sower,J000000,pilot4,C2,B-R00001,0

Output format sample:

1275543595|andrew|A|src/main.cpp|FF0000

Proposed translation:

• timestamp: ActivityDate converted to epoch
• author: Pilot
• type: Sowing will be considered an Add, Tending a Modify, and Agent will be considered Delete
• file: regionName/system
• color: By wormhole class: C1 #E9967A; C2 #FA8072; C3 #FF6347; C4 #FF4500; C5 #FF0000; C6 #DC143C

Regarding cache expiration, current preference is to use the below settings to allow Gource to hide any 'file' (cache) that isn't touched in an amount of time that should correspond to 30 real time days.

-i, --file-idle-time SECONDS
            Time in seconds files remain idle before they are removed or 0
            for no limit.

Gource config file is part of the repo - run with gource outfile.log --load-config gource.cfg (edit config to taste)
