Hi,

Can you provide more details on lexer generation such us all config
files and command lines.

Even using flex and skeleton files generated with JFlex 1.4.1 class
doesn't compile (Am I miss something?)

JFlex is really strange tool and plugin authors better can spend their
time to develop plugins not to dig with such tools :)

TIA,
Dmitry

Hi Maxim,
Is it same file that earlier was posted to forum?

I already try:
1. Download JFlex 1.4.1
2. Using ant task, JavaScript.flex(tuned a little, just change tokens class name) and attached skeleton generate .java for lexer.

Problems:
1. inside
void _*Token
appear return null
2. NPE during lexing file

TIA,
Dmitry

Dmitry,
would you please mail me faulty .java generated lexer? I'll look into.

Project sent _VelocityLexer.java is the problem lexer.

I get invalid chars in attached skeleton...
