Probably need a newer commit than rc0+0. Works on latest master for me.

[rapus95]

that means that rc0+0 wasn't built after the feature freeze?

[KristofferC]

Maybe it was a bug fix :p

[rapus95]

Clarification seems not to be worth a single word... :/

[KristofferC]

works for me on rc0+0 as well

@rapus95 I am getting this package ready to work on v0.5, but getting it to work on all pre-release versions is not an explicit goal. If you still see this error as we work to v0.5, please say something.

[rapus95]

@jakebolewski ok thanks, it seems to be a strange bug since it works at some places and doesn't at some other places :/
for me it still errors. my "fix" is replacing :(.!) by Symbol(".!")

@KristofferC are you on win10 64bit?

[jakebolewski]

@rapus95 the only place where that symbol is defined is

JuliaParser.jl/src/lexer.jl

Line 47 in 51ec761

[Symbol(".!"); :(<:); :(>:);

so I don't know why you are getting that error.

It seems worrying that behavior here is different on Windows / Unix for the same release candidate if that is indeed what you are seeing. The only way I could see that happening is that the rc for the windows builds is not built off the same commit as the tagged rc.

[KristofferC]

That is what the current code has:

JuliaParser.jl/src/lexer.jl

Line 47 in 51ec761

[Symbol(".!"); :(<:); :(>:);

[rapus95]

forget all i said until now... checkout to master obviously solved it -.-

But there still remains one question. What is .! for? the parser somehow doesn't seem to be able to parse it since the expression has to be written as a String. So how would i be able to use the operator without manually constructing the expression?

Always best to give Pkg.status() with all bug reports (or versioninfo(true)). The tagged version of this package doesn't work with rc0, but master here is apparently in better shape.
