1 year ago We could return fairly complete results except for the syntax that
allows you to call a function. However we will not be able to do this
in a performant way. It seems that we could try to use a linux find
command either locally or remotely, but formulating that command for any
string that you can have in the tree path may be tough. In addition we
would need a new mdsip entry point, probably a .fun for remote find
commands.
We have discussed in the past the desire / need for a database of shots, and an API to go with it.
I think we can add solving this to our longer term projects list.

Shot digit wildcards in path specifications like ~a are not processed correctly by getShotDB. ~t does get processed correctly. The code does not look like it makes any attempt to process it.
The drop down in jTraverser2 also ignores these wildcard paths.
The combinatorics on ~a through ~j with ten possible digits are enormous. I'm not sure that this function could ever be performant and return a complete result, but I hope I am wrong because "what shots exists" is a very reasonable question to ask. Minimally I think the limitation should be documented, perhaps even an automatic warning if getShotDB finds wildcards in the EXPT_path.
