That has been implemented in meantime. Just click on the download arrow and you can save the current window in CSV or PNG format.

 17 Sep 2008, Stefan Ritt, Info, New flag for auto restart
|
A new ODB flag has been introduced. When the logger is configured for automatic
stop and restart (/Logger/Auto restart = y), the restart delay was hard-wired
to 20 sec., which might be too long or short for some experiments. Therefore a

06 May 2021, Ben Smith, Info, New feature in odbxx that works like db_check_record()
|
For those unfamiliar, odbxx is the interface that looks like a C++ map, but automatically syncs with the ODB - https://midas.triumf.ca/MidasWiki/index.php/Odbxx.
I've added a new feature that is similar to the existing odb::connect() function, but works like the old db_check_record(). The new odb::connect_and_fix_structure() |

Since a long time we tried to convert all "static" mhttpd-generated pages to
dynamic JavaScript. With the new history panel editor we were almost there. Now I
committed the last missing piece - the equipment display. This is shown when you

12 May 2023, Stefan Ritt, Info, New environment variable MIDAS_EXPNAME

A new environment variable MIDAS_EXPNAME has been introduced. This must be
used for cases where people use MIDAS_DIR, and is then equivalent for the
experiment name and directory usually used in the exptab file. This fixes

|
Concerning naming of shared memories I went one step further due to some requirement of a local experiment.
The experiment needs to change the experiment name shown on the web status page depending on the exact
configuration, but we do not want to change the whole midas experiment each time.

Though ended with ".c", "lazylogger.c" has to be build with C++ compiler. I have

12 May 2020, Stefan Ritt, Info, New ODB++ API
|
Since the beginning of the lockdown I have been working hard on a new object-oriented interface to the online database ODB. I have the code now in an initial
state where it is ready for
testing and commenting. The basic idea is that there is an object midas::odb, which represents a value or a sub-tree in the ODB. Reading, writing and watching |

All this is very good news. I really wish this were available some months ago: it would have helped me immensely. The old C API was clunky at best.
I really like the idea and looking forward to using it (even if at the moment I do not have the need to) ... |
