Most probably an encoding issue in the typescriptdef.lex file. Il looks like the rule line 192, acts like [] was meaning something else such as a Chinese character... Not sure what to do here... you could try to remove/replace the rule and see what happens...

lgrignon commented 7 years ago

Hello, it sounds like you have an encoding issue or a wrong char, see this line in typescriptdef.lex:

  [锘縘 { /* ignore */ }

it should be []

9468305 commented 7 years ago

I double check this charactor typo issue. I am sure its not my local env encoding issue. It also has no relation to Windows Console GBK encoding.

When I replace it with [], build success. But left a warning as below.

by @lgrignon 's opinion, this should be OK, so I send a PR to you.

I suspect that some special character was once inside the [] but it got removed or hidden because of encoding, maybe because of saving or committing... I shall investigate the history when possible.

cyf-coder commented 3 years ago

Hello,

branch develop src\main\java\org\jsweet\input\typescriptdef\parser\typescriptdef.lex#193 special char still there

My editor default encoding is utf8, when i copy the line typescriptdef.lex#193 into my editor from github web page, the special char apear.

lgrignon commented 3 years ago

can you PR a fix if simple please?
