by ibit.zee:

go version go1.2.1 windows/386

command line is : go run _test1.go
error is : no buildable Go source files in C:\APL\!PROGRAMMING\GO

the problem is the underscore (_) in the file name, causes the file to not be found...

ZEE ;-)

Comment 1:

This is intentional.  Files whose names start with '_' or '.' are ignored (an underscore
elsewhere in the file name is OK).
However, I can't find any documentation for that, so changing this to a documentation
issue.

Labels changed: added repo-main, release-go1.3maybe, documentation.

Status changed to Accepted.

ibit.zee,
Why "!" in "C:\APL\!PROGRAMMING\GO"? Is that intentional?

Comment 4:

The relevant documentation is here:
http://golang.org/cmd/go/#hdr-Description_of_package_lists
"File names that begin with "." or "_" are ignored by the go tool."
#3: That is for the go/build package, not the go tool.

Comment 5:

the summary of the issue says this issue targets "go/build", not cmd/go, i was replying
to that.
also, cmd/go does point to go/build.

Comment 7 by anonymouzee:

A file starting with underscore '_' (or any other char, as in other main languages)
should be valid!

Comment 8:

A closed issue is not the right place for discussion of behaviour that is documented and
implemented.  Bring it up on the mailing list.
