Weird AUR error when uploading PKGBUILD for kde-qt-git

I was trying yesterday to upload my kde-qt-git PKGBUILD

http://aur.archlinux.org/packages.php?ID=31297

but, for _realver, I had a series of grep echo commands to find the version from files within srcdir.

BUT AUR, if I try to upload it with this variable enabled (not commented) it thinks that there is no build function (build () { .... } )

but ... there is one build function as well as a package function.

Why does AUR get "confused" ?

For security reason, the AUR doesn't source PKGBUILD.  So your _realver was probably confusing it.  Maybe it was taking _realver to be $(echo, skipping the rest of the line, and the mismatched parenthesis broke the parsing.

The AUR seems to parse ALL pound signs as comment symbols.  I noticed this a while back when I tried using bash syntax like ${pkgver##*_} and ${depends[@]/#/lib32-}.  It seemed to start after they fixed FS#13122, but I never (re)opened a ticket since these uses didn't seem too common.

As far as I can tell, Snowman is right.  When you uncomment the line, it thinks that the rest of the line is a comment (starting from the first pound sign), so it only sees this:

_realver=$(echo `/bin/grep '^

At that point, everything gets screwed up because the $( isn't closed properly.

Is it possible if I add a slash  --> \, that it isn't parsed as comment ? (example \# , instead of # alone)

You could try but I don't think it'll work.  It intreprets everything after _realver= as a fixed string, i.e no backslash-escaping. So it will probably set:
_realver=$(echo `/bin/grep '^\
then assume the rest of the line as a comment.
