Hi Matt,

 

At line no https://github.com/pyepics/pyepics/blob/master/epics/autosave/save_restore.py#L184, adding “-“ was a quick fix and its working.

 

Cheers

Sandeep Malu

Hi,

 

I am trying to save some of the PVs following the link

https://cars9.uchicago.edu/software/python/pyepics3/autosave.html

 

However when I try to save PVs which has hyphen (“-“) e.g .  Z-CAM:WARNING thows an exception “Expected end of line, found '-' “. But all other PVs autosave works fine. Any way to fix it?

 

 

Oh, yes, I see that this module is making bad assumptions about what a PV name can be.  This is at

 

which currently reads:

    pv_name = Word(alphanums+":._$()")

 

That would definitely need a '-' added.    For now, you could just add that to the `epics/autosave/save_restore.py` file on your system to see if that fixes the problem.

 

I believe this should also allow '{' and '}', but I'm not sure if there are other characters that should be allowed.

 

Is there a published regex _expression_ for valid PV names?
