[il-antlr-interest: 25476] Re: [antlr-interest] Tokens that span across char streams

That's very true. It's probably because performance is something that you can have a "feel" for as you look at some code, while memory usage takes a lot more (system-wide, sometimes) analysis to determine. Do you have any tips on how to keep the memory usage down for large files? And, how hungry i

I guess the tricky thing will be to insert this functionality without significantly adding to the run time.. If the stream has to check for macros, and also mux between the regular stream and the macro definition, I'm adding two 'if' checks on every single character. Maybe more if I'm also selectiv

Sam / Gavin thank-you. So, in the case I am receiving UTF-32 input, I would need to preprocess (using UTF-32-->UTF-16 algorithim) for characters in the 1 to 10 ranges and convert them into surrogate pairs, passing that input to ANTLRInputStream. In my lexer definition, where appropriate,

[il-antlr-interest: 25464] Re: [antlr-interest] Tokens that span across char streams

I failed to mention that the language requires a special character to be used before a macro *use*, which makes it easy to detect macros being used (and allows the flexibility of having it used just about anywhere)... the line below should read String a = #FOO end of a string"; Unfortunately, it'

[il-antlr-interest: 25460] [antlr-interest] Tokens that span across char streams

I have a language that allows macros to be used just about anywhere, which makes things a bit difficult. For example, a macro could define half a string, and something like this is legal: #define FOO "start of a string String a = FOO end of a string"; If I do on-the-fly substitution of macros by

I am working on an ANTLR grammar to support the ISO Standard Z notation (specification language). The Z character set includes many non-ASCII characters, so the lexer must recognize unicode character sequences, which, for lexer token definitions comprising 4-hex escaped unicode (\u), I believe

[il-antlr-interest: 25457] [antlr-interest] misunderstanding channel HIDDEN

Hi, I think I'm misunderstanding the usage of $channel = HIDDEN or skip(). I have text that looks like: 'b...@l^@a...@h^@' (most of the time the text is simply 'blah') and then it should come out like this: 'blah' my relevant rules are: startrule : BLAH; BLAH: 'blah'; UCODE

[il-antlr-interest: 25458] Re: [antlr-interest] misunderstanding channel HIDDEN

Your BLAH rule doesn't know that it can call UCODE between characters. You want something like this. startrule: blah; /* Probably also want to include EOF here, otherwise the parser will successfully run against "blahblah" */ blah: B L A H; UCODE : '\u'{ $channel = HIDDEN; }; B: 'b'; L: '

[il-antlr-interest: 25456] Re: [antlr-interest] Simplify tree construction rule

Hello, Does not really look that complex to me, but you could probably concatenate it in the lexer (but for that you need a real token) or use something like: tokens { SPACE = ' '; } aaa : 'TYPE' ' '? 'AAA' -> 'TYPE' SPACE 'AAA' ; However this will result in 3 nodes,
