Journaling in IRAF?

A. Springmann wrote on Jun 29, 2006

Hi all,

I was wondering if IRAF has a journaling function that records sessions, similar to the one that IDL has.

Any help or advice would be much appreciated.

Thanks,

I'm not quite sure its the same thing, but there are CL parameter to control logging of a session, i.e.

cl> lpar cl
      :
      :
     (keeplog = no)             Record all interactive commands in logfile?
     (logfile = "home$logfile.cl") Name of the logfile
     (logmode = "commands nobackground noerrors notrace") Logging control

When the 'keeplog' parameter is enabled the history is kept in the file specified by 'logfile'. The 'logmode' param lists all the things currently loggable, so to enable if just

cl> cl.keeplog=yes

Turn it off when you're done and see home$logfile.cl for results. There is also an 'stty playback' mode that we used to use for demos and test scripts.

Cheers,

helpful but somehow it doesn't work for me.

I did these settings and at some point it was working. But then it all stopped. I went back to the cl parameters just to realize that they have been reset. After I put them back to keeping a log, it didn't work at all.

This is what I am doing:

cl> lpar cl
     :
     :
    (keeplog = yes)            Record all interactive commands in logfile?
    (logfile = "HDR$logfile.cl") Name of the logfile

And my login.cl file contains

set	imdir = "HDR$"

so that my logfile is kept separately in each folder in which I work.

Any suggestions?

Thanks!

The "HDR" logical path is only used for image pixel files and isn't an equivalent to the current-working-directory. If you want to keep the log in the current dir, just set the 'logfile' param to be the filename 'logfile.cl' and it will be written to the current directory (even after you change directories).

Cheers,

Nice! Works again! Do you have any idea why it has switched off and does it usually switch off when one logs out and then logs in again?

Edit: Yes, it does switch off when I log out. Is there a way to make logging permanent?

The CL params apparently aren't learned, but that seems like a bug to me and I'll check up on it. In the meantime, you can simply reset the values in your login.cl/loginuser.cl file, e.g. add the following before the 'keep' statement:

cl.keeplog=yes
cl.logfile=log.cl

Great! This seems to work now.

Just one comment to others that might try to use this solution.

The correct code that has to be in the login.cl file should be:

cl.keeplog=yes
cl.logfile="log.cl"

That is, the name of the logfile should be in quotation marks. Otherwise it reports an error and IRAF refuses to start.

Thanks again!
