Initial remarks[edit]

At first glance, this article seems rather confusing. Some particular points that are unclear about the subject:

Are TBNFs supposed to be about building the abstract syntax tree, or do they aim to support more arbitrary transdunctions? The example details make it seem like it is translating an Algol-style language to assembly code, which is going further than just parsing.
Are the various emit statements correct, or have they been garbled? Several linebreaks seem strange.
How is the priority section to be interpreted? Normally priority is enforced in the grammar, and that is done for the relation class of operations but not for distinguishing plus and minus from times and divide!
What is the meaning of the ... that is sometimes suffixed to nonterminals in the grammar? Why are some nonterminals with angle brackets and some without?

And all of that is just from looking at it for 5 minutes! There are probably more problems. 130.243.68.115 (talk) 10:46, 4 October 2017 (UTC)[reply]
