Hi David
I have two questions:
To (system "...")
1: There are several commands, wich can write the generated EPS to
stdout. Is there a possibility to catch that and integrate it without
creating a temporary file?
See the guile documentation, node "Pipes".
OK, thanks!
2: Is there a way to get the result code and see if the command succeded?
Uh, have you even looked up "system" in the guile documentation?
Yes I have ... but I typed my question a bit to fast ... the question should have been, why does '(if (not (system ...' not act, like I would expect. But with '(if (= 0 (system ...' it does.
Sorry for the noise!
