/*******************************************************************************
* Instrument: Test_NeXus_output
*
* %I
* Written by: Peter Willendrup
* Date: October 2026
* Origin: DTU
* %INSTRUMENT_SITE: Tests_other
*
* Regression test of the NeXus writer of the McCode runtime.
*
* %D
* Monitors of every NeXus output kind (0D, 1D, 2D, Monitor_nD histogram,
* Monitor_nD BINS maps of rank 2 and 3, and an event list) for
* test_nexus_output.py, which runs this instrument with --format=NeXus,
* serial and with MPI, and checks mccode.h5 with h5py:
*
*   - string values containing '%' are stored as given (instrument parameter
*     'tag', component parameter literal 'filename="f%%1"')
*   - all string attributes and data sets are printable text
*     (no uninitialised memory, e.g. in the Monitor_nD BINS output)
*   - no debug output on stdout
*   - a monitor with a very long file name ('longname', about 1000
*     characters) does not crash the simulation or lose other monitors
*   - a second run with --append adds entry2 to mccode.h5
*
* The instrument also runs in the default (McCode) format.
*
* %P
* tag:      [str] String stored in the NeXus file, containing '%'
* longname: [str] File name of the 'lmon' monitor
*
* %L
* test_nexus_output.py next to this instrument.
