Although using softwares to design a pattern is functional and interesting, these softwares are designed for special loom machines and their output data managed to fit them. In a Grasshopper algorithm, possible methods to generate a pattern can be as follows:
1-
Pattern Data as a stream of Booleans (True/False). Boolean values could associate with the warps, tell them which one should be raised, which one not. (i.e. T, F, T, F, F, T, T, T, F, T, ‌)
2-
Pattern Data as Tables (i.e. Excel / Spread sheets). Values on the table (like 0/1) can be associated with warps to go up and down. 0 1 1 0
3-
0 0 1 1
1 0 0 1
0 0 1 0
Pattern Data as Graphic reference (i.e. Bitmap images). These images can be used from external resources like visual output of software packages or huge amount of graphical references of patterns available in books or on-line.

4-
Pattern Data can be set internally via available Grasshopper components which is more abstract and probably numerical (includes series of numbers, random values, domains, ‌).
