[GAP Forum] Technical question / interface

[Thomas Rehn]

Hello,

for a research project I try to utilize the group calculation facilities of 
GAP. Due to performance and design issues the main program implementing 
various algorithms is written in C and C++. For using GAP I wrote a wrapper 
class (which uses popen and two pipes) for the GAP binary and its command 
line. The problem here is that on writing a "g := Group(...);" command 
the "gap> "-prompt appears twice (whereas on other used commands it appears 
only once), so I have no unique easy mark to use to recognize the end of a 
GAP calculation. Treating the group assignments separately waiting for two 
prompts would be possible, but this is not a very general approach.

Do you know a better way to interface GAP for this purpose or a flexible 
workaround for the prompt-mark problem?

Best regards,
 Thomas.
