This parfile:
ActiveThorns = "IOUtil Cactus"
results in an error:
$ exe/cactus_sim -S firstline.par [...] Activating thorn Cactus...Success -> active implementation Cactus Activation requested for --->IOUtilCactus <--- Error: Thorn IOUtilCactus not found Activation failed - 1 errors in activation sequence WARNING level 0 from host ekohaes8 process 0 in thorn Cactus, file /data/rhaas/postdoc/gr/cactus/ET_trunk/src/main/SetParams.c:93: -> CCTKi_SetParameter: Error at line 1 in parameter file firstline.par while activating thorns
since the parser incorrectly removed whitespace (a newline) at the end of the first line of the multi-line ActiveThorns value.
My (untested) guess is that these lines in par.peg is repsonsible:
stringfirstline = .
stringcomment = #.*
stringparser = ^({var}|{name}|{stringfirstline})*(\n({stringcomment}|{var}|{name}|{any})*)?$
since it will make the \n in (\n({stringcomment}|… not part of a stringcomment, a var, a name or an any group.
