Am I right in thinking that the TMFE HandlePoll function is calle once per
PollMidas()? And what is the difference to HandleRead()? |

12 Sep 2023, Maia Henriksson-Ward, Suggestion, Syntax highlighting for sequencer scripts
|
Recently I was trying to read sequencer scripts written by a previous student, and realized it would be easier to
quickly read/skim sequencer code with some form of syntax highlighting. I've been using Visual Studio Code as my
editor, so I made myself an extension for VS Code that provides basic syntax highlighting (with help from

I like the idea of syntax highlighting, but your solution is just for one editor which not everybody
is using. It would be better if the editor built into mhttpd for MSL files would have the possibility.

I had to switch to Visual C++ 2005 under Windows. This required the upgrade of
all project files under \midas\nt\ and fixing a few warnings, since the new

20 Jan 2009, Stefan Ritt, Info, Subrun scheme implemented
|
A new "subrun" scheme has been implemented in mlogger to split a big data file into several individual data files. This feature might be helpful if a data
file from a single run gets too large (>4 GB for example) and if shorter runs are not wanted for efficiency reasons. The scheme works as follows:

Hi Stefan,
My colleague Tobi Raufer (tobi.raufer@stfc.ac.uk) has tested this new implementation and
sent me the following questions:

[quote="Renee Poutissou"]I have tested the new subrun functionality a bit more and I have two observations. First, it seems to work on a basic level, i.e.
subruns are created, which are equal in size. However, I can't relate their size to the byte limit set in the ODB.[/quote]

Hello everybody,
I have a strange JS behavior. In one of my frontends I create a key in the ODB with:

you can also do this from javascript, too, using the db_create rpc call, see mjsonrpc_db_create() and
