I code in Python; here are some of my software tools:

• pylingdocs: Write data-rich linguistics documents. You can integrate data from CLDF datasets, and output to a variety of formats.
• pyradigms: Generate customized (linguistic) paradigms from a list of entries with parameters or vice versa.
• clld-morphology-plugin: a plugin for modelling morphology in CLLD.
• expex-acro: glossing abbreviations and useful linguistic markup commands for LaTeX
• cldflex: A set of scripts for converting FLEx .xml output to CLDF .csv files.
• biblatex2bibtex
