This project maintains reusable collections of common file extensions categorised per typology. It can be used by any program to quickly distinguish between file types. It acts faster than mime/type or libmagic recognition, but is of course less precise.
Each collection is a file named after a generic typology stored in data/:
- archiv :: archives and disc images
- video :: moving images
- audio :: playable audio
- text :: text in human languages
- code :: code in machine languages
- image :: static images
- sheet :: spreadsheets
- slide :: presentations and slides
- web :: web developers bread and butter
- font :: typography fonts
This repository also contains source code in render/.
For now it is just a zsh script build-zsh-parser which when executed
will render a file file-extension-parser.zsh containing a zsh
function file-extension-parser() that can be sourced, takes a
filename and returns the typology of file examined according to the
archived extensions in data/.
This implements a fast approach to recognition of file extensions, in case of zsh it relies on a switch case construction and two string modifier operations that are completely native to zsh.
Other source will be include in the future (as needed or contributed) to populate database or key/value stores or generate code in other languages.
