this is a work in progress
woving is a domain specific pattern language, or notation system, for writing concise loom draft instructions. It implements features commonly found in weaving, like repetition and symmetry, into the language itself.
instructions for a loom draft, whether those for the threading or for the treadling sequence, can be thought of as an array of numbers. seen in this image, the striped cells at the top and right-hand side represent the instructions graphically.
this screenshot is from another digital weaving project of mine woven images
as just numbers though the threading and treadling would be:
234122233344411112341143211114443332221432
12341212323434141234143214143432321214321
in woving, those lengthy sequences collapse down into a conciser and clearer form, denoting repetition, symmetry, and where values move incrementally up or down:
[2341 2:3 3:3 4:3 1:4 2341]|
[/14/12/1324/3414/14/1]!
some transformations happening here are:
1:4
would become1111
(repetition)/141/
would become1234321
(a 'step array')123|
would become123321
(symmetry)123!
would become12321
(odd symmetry, or 'point symmetry')
- install nearley.js with
npm install -g nearley
- Compile the woving.ne file (which contains the grammar for the language) with
nearleyc woving.ne -o woving.js
- install node packages
npm install
- run the test suite with
npm test
