Is there a way to setup a search, to search several log books but not all the logs books at one time?

Thanks

Carl

No. You can either search one logbook or all logbooks. There is however the way to have separate groups of logbooks, which are "invisible" from each other. Like running several elogd daemons at the same time. Then your search on all logbooks will only run on the logbooks of one group. Check the documentation for "top groups".

Hi,

I'm currently trying to setup a logbook which will contain process descriptions. One of the attributes will be the resists that are used. This could be more than one resist, hence I try to use MOptions but users should also be able to add materials to the selection list. When I write the following, I get some problems though:

Required Attributes = Name, Author, Resists
MOptions Resists =  Nano Copolymer EL-10, S1813
Extendable options = Resists

If a user wants to add a resist, he gets a textbox to add the new resist (which will contain what was already toggled), but there is now way to select also other resists that are already available, without saving the post and than edit it again. Previously selected resists are deselected when a new resist is added (if the user had emptied the textbox) and one can not save the newly added attribute option without saving the whole entry.

Is there a nice way to implement this (am I overlooking an obvious solution), or is this not possible at all. I guess an ideal solution would be to get some sort of ok button when one adds an attribute option and after confirming the new value that one gets back to the checkboxes without exiting the edit mode.

Regards,

Michaël

PS: This is the complete config for this logbook:

Theme = default
Page Title = $logbook - $Name
Edit Page Title = $logbook
Comment = Photolithography Processes

Quick filter = Name, Resists
Preset Author = $long_name
Reverse sort = 1

Attributes = Name, Author, Resists
Sort Attributes = Resists, Name, Author
Required Attributes = Name, Author, Resists
MOptions Resists =  Nano Copolymer EL-10, S1813
Extendable options = Resists
Sort Attribute Options Resists = 1

List display = Name, Author, Resists

If you use an attribute "Entry" then the internal variable "entry time" will expand to the last value of
"$Entry"+" time", e.g. if you use it in "Thread display = $entry time, ..."

One side effect is, that the logbook selection page defaults to use
Last submission = $entry time by $author
Which then expands to an undesired result.

This is not really a bug, rather something you'll need to keep in the back of your mind.

A query to a logbook can crash the demon.

I have a logbook with data in it that I need  to  rename  and preserve the the existing data (old book) in the newly named book (i.e. can I move all of the data from one book to a new book and than delete the data from the original book)?

As always thank you for your time.

There are two ways:

1) Create a new logbook, add the "Copy to" command to the old logbook. Select all entries and copy them to the new logbook, and delete the old one.

2) Change the logbook name in elogd.cfg, by manually editing the file, then rename the subdirectory in your file system from the old to the new name, then restart elogd.

The second solution is much simpler, but you have to manipulate files and directories yourself.

Whatever you do, make sure to back up you files before any operation. 

 Sorry, about this dumb question but with  "Copy to = <logbook list> " what is the format of  <logbook list>?

Is it just the "logbook Name" or is it the actual path name   "http://something/somethingelse"?

 In order to copy (or move) files from one logbook to another, you first need to ensure that  the
appropriate commands are in the section of elogd.cfg of the logbook the files move *from* (called 'current')

 - made up elogd.cfg to show this, and obviously only the pertinant lines

[Global]

Group = current, Y2011, Y2010, Y2009...

...

 [current]
...
Menu commands = New, ... Copy to, ...
...
Copy to = Y2011, Y2010, Y2009 ...
...
 - end of made up example.
 
So to solve your problem, the <logbook list> is simply the list of logbooks in
this part of elogd.cfg after the 'Copy to =' line in the elogd.cfg file (Y2011, Y2010, Y2009...)  

You also need to ensure that the directory to which the entries are to be copied to exists!

('Move to' would be faster if you are going to delete the entries in 'current' afterwards, but as always, it depends on

your perception of risk.)

For the user, the logbook list is the set of logbooks that appear in the
drop-down menu by the side of "Copy to" in the menu bar, and it allows you to
move that entry (or thread of entries if more than one) to the selected destination.

My reason for answering this is because I have actually done this operation 'in
anger' some time ago and regularly since, and would have answered before if Stafan had not beaten me
to it.  I used what was Stefan's second method, which, for those who are
reasonably confident with file manipulation, is far faster, and, dare I say,
less prone to 'unexpected' issues - some here will know what I'm
getting at.

So I say, "Back up your files and take the plunge", I would have put something
else but this is a family friendly forum.

But you must bear in mind my views are those seen through the filter of a
regular Elog ab-user, which may be why Stefan worked so hard to answer before
me ;-)

Anyway, Stefan <i>et al</i> have got CERN's faster-than-light particle problem to deal with this morning.

I would be too lucky if I just could fix this as I fix some ELOG problems! I guess hundreds of physicists right now are pondering about what could have gone wrong in data taking, because nobody really believes that this is a real effect. 

 Got it to work, manipulating the files was not that hard once I got over the FEAR factor.  Good luck with the speed of light thing.

 Well done Mike!

One result is that I've also learnt things, realised that there are some known unknowns and perhaps some unknown unknowns in my

understanding of Elog.

We have about 10 logbooks running on the same Elog that all get fair use. Many people have turned off new entry emails because they were filling up inboxes, but are still interested in what's new. I saw the option to add "?last=1" to the start page, although I'm afraid using it might cause confusion over how to get to the older posts.

I was trying to figure out a way of creating a "digest" of sorts, a list of entry subjects posted in the past day or week, something similar to what's generated by "?last=1?mode=threaded", but for every logbook (similar layout to the selection page with nested logbooks). This could either be a page, or a regular email.

Is there way to generate such a cross-logbook page? What about a scheduled email formatted based on a given filter?

PS: The elog has been invaluable to us, a big thanks to all involved!

What we do is use the RSS feed of elog. This gives you nice summaries without going through your email inbox. Most browsers have RSS readers, there are also tons of stand-alone programs for that. Attached is a screenshot from the Google Reader subscribed to this logbook and to the "contributions' logbook. You see nice one-line summaries, you can expand them, and you can go directly to the logbook if you click on the arrow. The second image is from the Firefox using what they call "live bookmarks", but it's basically a RSS reader.

To make this work, I installed the RSS extension of Google Chrome (Firefox has this under "Bookmarks"/"Subscribe to this page"), then go to the elog page, then click on the RSS icon, then clicked on "Subscribe to this" via Google Reader. Just a few clicks.

Hope this is what you want.

 Perfect! I didn't not know there was RSS support. I will probably use something like rss2email, but this is exactly what I needed. Thanks!

I have two identical servers (IBM X337) setup on the same LAN with Ubuntu Linux 10.04 LTS with ELOGD running (Compiled from tarbell) with the same exact package install base. (Only difference between the two servers is the hostname, and the ELOGD.CFG global section)

Some user wanted to modify the URL by hand and succeeded to crash the elogd process with npp=now
It appears that npp=0 crashes elogd with the following error message:

Program received signal SIGFPE, Arithmetic exception.
0x0808eba2 in show_elog_list (lbs=0xab3c770, past_n=0, last_n=0, page_n=1,
    default_page=1, info=0x0) at src/elogd.c:20214
20214            sprintf(str + strlen(str), loc("Page %d of %d"), page_n, (n_msg - 1) / n_page + 1);

I guess this bug is not OS dependent: you can crash every logbook that you can search ;-)

> [...] It appears that npp=0 crashes elogd [...]

Here's a patch: search for "npp" in src/elogd.c and add the following line:
  if (n_page<=0) n_page = 20;

Here's the diff output for version 2.9.0-2414
*** 20092,20096 ****
     if (isparam("npp"))
        n_page = atoi(getparam("npp"));
