For enu, we absolutely need to track slit configuration : home, tool coordinates systems which come from the slit alignment procedure. For now, I was pushing it as a keyword so I can retrieve the history from the archiver.
But I agree that ics_config would be a good place to put it.

We need to talk about that next week, especially if we link that to alarm handling also

Showed proof-of-concept to Fabrice and Arnaud. Since they will be using this, I'm asking Arnaud to review. I'd like to come out of this shutdown using both INSTRM-119 and INSTRM-28

INSTRM-28 is a partial requirement, since it provides a namespace for spectrograph ID interpolation.

Interpolation is currently only done on individually fetched strings, which I think is sufficient for current needs. I think I should add an option to recursively check for strings in the returned data structure.

That's good for me.
The syntax of the YAML file can be a bit tricky. But they are really powerful and interpolate names allow to factorize even more.
It will definitely make our life easier.

which part did you feel tricky? we might be better to have them documented not to get confused and bug..

This ticket is marked as review completed, but nothing has done on github.
Just raise what to do cloomis / arnaud.lefur.

Ticket has already been addressed as part of other work.
