[etrice-dev] Grammar analysis

[Henrik <hrr@xxxxxxxxx>]

Hi developers,

recently I had a really hard time to hunt down an ambiguity in a fairly complex grammar.
(I re-used part of our eTrice ROOM grammar and removed and replaced some parts.)

Finally I found a nice article [1] that pointed me to a tool [2] which helped me to resolve the problem.
The grammar check of ANTLRWorks marked the ambiguous parts red (upper left pane) and showed the ambiguous alternatives graphically in the lower pane.
