piraha does not allow variable expansion in ActiveThorns

[Roland Haas]

Piraha fails to allow things like:

$thorn = "PUGH"
ActiveThorns = "$thorn"

since it looks for “ActiveThorn” lines before parsing anything else of the parfile (this is in src/piraha/Call.cc in cctk_PirahaParser line 1072.

It should not do so since the documentation http://einsteintoolkit.org/usersguide/UsersGuidech7.html#x10-320023 does not document “ActiveThorns” to be (that) special.

No. Obviously, nothing should happen before the release.

Possible hackathon task.
