Dear all,
I need to integrate in my MIDAS project the communication with an OPC UA

These changes to make 32-bit and 64-bit ODB binary compatible with each other are now commited to midas svn, revision 4080.

I'm interested in using the matching feature for ODBSET explained on
https://midas.triumf.ca/MidasWiki/index.php/Sequencer for settings that are in an
array, like:

Hi,
I guess the issue is in the "[?]" part of the command, the indexing is handled differently from the odb path and does not
support "?".

I created some keys in my ODB to try to match yours.
The ODBSET commands you wrote are all working fine (of course with different results), except only for the "/Detectors/Det*/Settings/Charge/Bias (V)*"
which I will have to

I think the issue may be the version of MIDAS I'm using. Mine is current as of February 4, 2020.
But since then there have been changes to the sequencer code, specifically parts that handle indexing.

I totally agree that we should have a consistent formatting for array index expansion.
I had a look to the mjsonrpc code and I found the function parse_array_index_list(...) which does this job.
I have a similar function (adapted form previous code) in odb.cxx called strarrayindex(...) that is designed for the same "consistency" purposes between |
