By the way, here is a little more detail on one of the issues that I
encountered. In pegs.nim (0.19.2 and devel), in the parsePeg proc, the
PegParser var that is created seems to get re-initialized after the init call
returns when running in the VM at compile time.
The existing code looks like
var p: PegParser
init(PegLexer(p), pattern, filename, line, col)
# p.buf, etc should now be set from init call, but are not
Run
The workaround that I was using for my previous experiments added a separate
PegLexer var to use in the init call, and then afterwards copied the data into
the PegParser var.
var p: PegParser
var l: PegLexer
init(l, pattern, filename, line, col)
p.bufpos = l.bufpos
p.buf = l.buf
p.lineNumber = l.lineNumber
p.lineStart = l.lineStart
p.colOffset = l.colOffset
p.filename = l.filename
Run
It's not clear to me why the PegParser var gets re-initialized when running in
the VM at compile time, but not in regular code, but that workaround above was
at least enough to let me proceed with my tests.
Anyone have any thoughts on why that happens and/or pointers in Nim's source
where I might investigate more?
