Hi sean Xtreams? Just to be sure is PEGParser built using Xtreams? Stef Le 23/6/16 à 02:20, Sean P. DeNigris a écrit :
I converted parts of rfc 5322 to the following: grammarEmailAddress
^'addrspec <- localpart "@" domain localpart <- dotatom / quotedstring /* obs-local-part */ domain <- dotatom / domainliteral /* obs-domain */ domainliteral <- [CFWS] "[" *([FWS] dtext) [FWS] "]" [CFWS] dtext <- [\x000021-\x000050] / /* Printable US-ASCII */ [\x000054-\x00007E] /* characters not including */ /* / obs-dtext ; "[", "]", or "\" */
/* rfc5234 B.1 */ ALPHA <- [\x000041-\x00005A] / [\x000061-\x00007A] DIGIT <- [\x000030-\x000039] HTAB <- [\x000009] /* horizontal tab */ SP <- [\x000020] WSP <- SP / HTAB
/* 3.2.2. Folding White Space and Comments */ FWS <- ([*WSP CRLF] 1*WSP) /* obs-FWS */ ctext <- [\x000021-\x000027] / [\x00002A-\x00005B] / [\x00005D-\x00007E]
ccontent <- ctext / quotedpair / comment
comment <- "(" *([FWS] ccontent) [FWS] ")"
CFWS <- (1*([FWS] comment) [FWS]) / FWS /* 3.2.1. Quoted characters */ quotedpair <- ("\" (VCHAR / WSP)) /* / obs-qp */ /* 3.2.3. Atom */ atext <- ALPHA / DIGIT / "!" / "#" / "$" / "%" / "&" / "''" / "*" / "+" / "-" / "/" / "=" / "?" / "^" / "_" / "`" / "{" / "|" / "}" / "~"
atom <- [CFWS] 1*atext [CFWS]
dotatomtext <- 1*atext *("." 1*atext)
dotatom <- [CFWS] dotatomtext [CFWS]
/* 3.2.4. Quoted Strings */ qtext <- [\x000021] / /* Printable US-ASCII */ [\x000023-\x00005B] / /* characters not including */ [\x00005D-\x00007E] /* "\" or the quote character */ /* obs-qtext */ qcontent <- qtext / quotedpair quotedstring <- [CFWS] DQUOTE *([FWS] qcontent) [FWS] DQUOTE [CFWS]'
When I evaluate: parser := PEGParser parserPEG parse: 'Grammar' stream: PEGParser grammarEmailAddress actor: PEGParserParser new.
I get: KeyNotFound: key 'quotedstring' not found in Dictionary
How am I supposed to debug that to find the typo in my giant string above?!
