CUCC Expedition Handbook
Troggle - what it is
Troggle is the software which runs the the expo cave survey data management and website.
Troggle - what it does
Troggle manages all cave and expo data in a logical and maintainable way
and publishes it on the web.
The troggle software is written and maintained by expo members.
Examples of troggle-generated pages from data:
Troggle - why we developed it
- Coherently publishes expo data by cave, by expedition, by person, by trip or by survey - without requiring duplicate data entry.
- Manages and safely archives the typed and scanned survey data, entrance data, trip records (logbooks) and expo records.
- Enforces consistency - making it easier to detect mistakes and omissions
- Publishes the "guidebook descriptions" of caves by a combination of online forms and uploading files.
- Supports the process of turning scribbled notes into finished cave surveys
- Generates prospecting guides so that we don't waste time looking at holes which have already been explored
- Reformats the webpages such that they have a coherent style and have a small menu at the top-left
hand corner. These are the handbook you are reading now and the historic records of past expeditions.
- Provides a way of editing individual pages of the handbook
for very quick and urgent changes.
[This is the "Edit this page" capability; see for
how to use it and how to tidy up afterwards].
Troggle - who uses it?
The "use-case" users are described in Who needs to know What and When.
Troggle - where it gets the data
All the data of all kinds is stored in files. When troggle starts up it imports that data from the files. There are other scripts doing useful things (folk, wallets) and these too get their data from files.
There is never any need to back up or archive the database as it is rebuilt from files. Rebuilding troggle and re-importing all the data on the server takes about 4 minutes (as of July 2020).
