Waveshaper

WORK IN PROGRESS!

A simple proof of concept implementation of a tool that draws waveforms, done in python. This is a simple way to play around with architecture before implementing the thing in a stricter language.

It draws huge inspiration (wave shapes, drawing methodology) from the tikz-timing package by Martin Scharrer.

Executables

• test.py: just there to play around
• create_overview.py: creates overview.html which contains all symbols and transitions

symbol ::= [a-zA-Z]
identifier ::= [a-zA-Z_]+
value ::= identifier
string ::= '"' [^"]+ '"' | [a-zA-Z0-9]+
natural ::= [0-9]+
float ::= number ('.' number)? | '.' number
parameter ::= '{' sequence '}' | string
parameters ::= parameter ( "," parameter )*
instruction ::=   float? symbol ( '(' parameters ')')? 
                | '[' ( indentifier '=' )? value ']'
sequence ::= number? '{' instruction+ '}' | instruction+

TODO

• much that is not on this list
• metastable symbol?
• pattern for X
• weak H/L symbols?
