Same with the Parse Tree
graph not a 'hierarchy'
Thanks for the input, I'll look into this tomorrow again :), as you say I'm iterating the parse structure for every Pulse... but probably messed up the Msagl graph building part due to lack of insight on the different node types - I started looking into how the ParseTreeEnumerator works
that should probably make things clear
btw, what's the difference between the ITreeNode and IForestNode?
both seem to be very similar - the IForetNode are the actual parse nodes that are created during the parse
then you do transformation to ITreeNode during the ParseTreeEnumerator enumeration
is it in order to "hide" some "internals" from the parse phase?
the and nodes represent each ambiguous branch
when you have ambiguity more than one and node will exist at the site of the ambiguity
i implemented a couple traversal algorithms, need to check if the parse tree enumerator has any bugs
though I don't like the Ebnf syntax at all :/ - thats why I started on a custom Bnf like syntax closer to the one in Antlr
I find that one much easier to follow / understand
the RapidBnf in my RapidPliant repo
part of that one I want to have things such as "parameterized" rules
for things similar to "list" and what not
though the Unicode support would mean the lexing would need to be extended to support full unicode set
I could be wrong on that though
no, it didn't - it was only for the default character classes
and it was for the regex parser, is that what you use in the Ebnf?
I think so
I put the regex grammar in the ebnf grammar
well, If you want I'll look into that later today
I'm using the Regex grammar too ;)
though it will most likely require rewriting the grammar?
i I remember correctly it was designed to only take a single char after the "\"
on grammar level
like you said the grammar may have some issues
EscapeSequence lex rule is the one I think needs to be looked at
and its just a dfa
I finally found the bug in my implementation
214 ms to parse the large json file
the benchmark was even better @ 186.244 ms
Hello! Can you please tell me, I want to use this project here: https://github.com/uxmal/pytocs But I don't know how to insert a project in Python. If anyone has worked with this please show.
