hi all, I try to make a plugin who can colorize some line like
FROM lkfsjdl IMPORT lskdfjl;
FROM lkfsjdl IMPORT lskdfjl;
Based on my own grammar created with ANTLR 3.0.
for that, I overrided ITokenScanner.
public IToken nextToken() {
antCurrentToken = lexer.nextToken();
if (antCurrentToken.getType() == org.antlr.runtime.Token.EOF)
return Token.EOF;
switch (antCurrentToken.getType()) {
case LyaflplugLexer.TAG_END:
case LyaflplugLexer.TAG_DEFINITION_MODULE:
case LyaflplugLexer.TAG_FROM:
case LyaflplugLexer.TAG_IMPORT:
return keyword;
default:
return ident;
}
}
The problem is : if the file is empty then I can create twho line
FROM lkfsjdl IMPORT lskdfjl;
FROM lkfsjdl IMPORT lskdfjl;
he color eatch word etc... everything is perfect but if I save and I
reopen the file he bug cause theres are two line who are the same. (if
there is only one, no prob).
I ve tried to debug and he call every token. but after that there is a
exception error Argument No valid.
is any body has a idea: I there is the class code

thanks
