Hi,
I want to write a macro that checks for some settings and if the settings
are wrong stop the current compilation and terminate with an error
message. Right now I have
\def\ERROR
{\writeline
\showmessage\??externalfilter??{forbidden}\getexternalfilterdirectory
\batchmode
\normalend}
This prints the error message on the terminal and exits. However the exit
status (the value of $?) is 0, if the tui file has changed the document is
compiled a second time anyways.
How can I force context (the macro package) to exit with a status of 1 so
that context (the program) does not attempt a second compilation?
Thanks.
Aditya

It does not send the program's error code to 1. After compiling \starttext \forcequitjob{bye} \stoptext the output of `echo $?` is 0, so context thinks that the program compiled sucessfully. Now add \section{one} on the first line and compile again. Context does two runs of the program (because no error signal is generated at the end of the first run). I want to avoid this second run.

Adding \errmessage{} before \normalend changes the error code to 1.

I want the code to also work with MkII, so I did not even think of a lua solution :) Aditya ___________________________________________________________________________________ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / http://www.ntg.nl/mailman/listinfo/ntg-context webpage : http://www.pragma-ade.nl / http://tex.aanhet.net archive : http://foundry.supelec.fr/projects/contextrev/ wiki : http://contextgarden.net ___________________________________________________________________________________ ^ permalink raw reply [flat|nested] 9+ messages in thread

I had some functionality (running content through webservers) that was MkIV only, but I decided to remove that. Maybe that is what give you the MkIV only imression.
