In fact, I d=E0on't think manpage must be necessarily ported to xslt and
friends, as the online documentation won't be just this, but an
explanation page for each driver and plugin, and 'general' docs about
layout and configuration.=20
But we may include the manpage somewhere too.

In fact, our use of XSLT (as I see it in my mind) is writing xhtml pages
with tags like <conf></conf>, <code></code> which will be replaced by
the apropriate xhtml/css code. The page should just describe the body
and the rest (head, menus, ...) would be generated by the stylesheet.

So, in this case we can use two stylesheets : one for the online doc
(including php code for the menus, ...) and one for documentation in the
tarball with a little menu and summary.

In fact, I found the logidee tools in the debian distro, without knowing
they were written by frenchies, and then I remembered logidee was an
'SSI' which writes docs (and a distro if I remember well)

It's just a set of xslt/dtd files and makefiles, no binary there. I know
the documentation is in french only, but I just mentionned it, we can't
use the stylesheets as is, I'll write others myself, based on the good
ideas these guys put in there.

Both, read at the beginning. This is why xslt is a good choice IMHO, as
we can generate both static XHTML and PHP with two stylesheets.

Hello Matt !

In fact, there are two lists for lcd4linux : lcd...@li...  for user questions (and support) and lcd...@li... for developers discussions and support about CVS version (which will become 0.10.0 version soon).


You should have posted to lcd4linux-users, but for this issue let's
continue in this one.

Err... can you elaborate ? What is this Powertip display ? Is it
HD44780-based ? Which size is it ?
We can't know all display favours, especially HD44780 ones, please give
more details.

Moreover, you may think about using the CVS 'NextGeneration' lcd4linux
as there are a lot of bugfixing for all drivers and a new layout, and
old generation (up to 0.9.12) won't be upgrated.

Hi

I don't know if this is the correct mail address, or if their is a forum I can visit, but I am having a few problems with lcd4linux.

I have a PowerTip PC1604 display. The top two lines display ok, but the botton 2 lines are indented by 4characters.

I don't supose you know why this could happen.

Re: [Lcd4linux-devel] how to make documentation ? maybe xslt !

[Jerry S. <ye...@th...>]

Hi Xavier,

I played around with the docbook source and got it to export to
html using xsl.  Is this what you were looking for? See:

http://www.thegeeks.net/~yello/lcd4linux.html  <-- html
http://www.thegeeks.net/~yello/lcd4linux.sgml  <-- docbook source
http://www.thegeeks.net/~yello/lcd4linux.1     <-- man page

Technically the .sgml file is now xml as well...

The command line I used to generate the html was:

xsltproc /usr/share/xml/docbook/stylesheet/nwalsh/html/docbook.xsl \
lcd4linux.sgml > lcd4linux.html

I had to install the xsltproc and docbook-xsl packages in order to do
this.

Nod.  I have converted my original man page over to docbook.  I've been

I agree that XSLT is easier to use than dsssl and think it would be 
a better choice to transform the docbook source to html.

Bah.  lcd4linux will still be here once school is done. :)

As for as logidee is concerned, one problem with it is the
documentation.  Since there is no documentation written in English,
it leaves english-only speakers such as myself in the dark.  You would
have to do it all...

Is the logidee package simply a set of XSLT transforms, or is there more
to it?

Do you want the documentation that is in (X)html format to be only html,
or do you need to have php source in them so that they integrate with
the rest of the website?

[Lcd4linux-devel] how to make documentation ? maybe xslt !

[Xavier V. <xav...@fr...>]

Hello list ! (Jerry, I put you in CC in case you weren't in the list)

While browsing blogs, I found a discussion about php versus xslt versus
m4 versus docbook versus Perl ... on how to automatically generate html
pages with scripts, and I remembered our little project (which seems
sleeping this month).

I don't renounce to php, don't panic ;) But there was the problem of
documentation. Somebody (me ?) proposed to look at docbook, but it's
definitely too hard for me to create dsssl stylesheets, and moreover my
docbook installation seems broken :/ Another solution was to use XML
stylesheets with docbook, but the situation is even worse in my poor
woody.
A good solution appeared to me : XSLT. Don't rush on
google.[fr|at|com|de|...] and read more : XSLT works with a xml document
containing the text and some markup and a xsl stylesheet, which defines
how to do the transfomation from xml to whatever other markup language
(in our case, xhtml). The best (most complete) xslt processor seems to
be xsltproc and it does very well its job.

So, then I found the logidee-tools. It's avaible at
www.logidee.com/tools/ or in a debian package for the power users ;).
It's a compilation of stylesheets and make scripts to write courses and
publish them in html or pdf/ps (via LaTeX). And it's written by two
frenchies ;)
We can't use the stylesheets as is, but I'll be easy to adapt them to
our needs (one for the website, another for documentation in the
tarball). I'll try work on it soon, but I have to go back to school
tomorrow :(

[Lcd4linux-devel] configure patch

[Xavier V. <xav...@fr...>]

Hello Michael, hello list !

I modified deeply the autoconf/automake stuff to be able to choose the
plugins we want, just as drivers :
- first, I did some cleanup and moved drivers stuff to drivers.m4, and
created plugins.m4 to handle plugins stuff

- there's a new configure switch : --with-plugins, which should work as
--with-drivers (as I copied a lot of code), but strangely all,!a_plugin
doesn't work ! I have to work though it tomorrow.

- I modified plugin.c in the same fashion as drv.c, and it initializes
just the plugins whose WITH_... config.h option as on.

- Here are the advantages :
* mysql plugin works out of the box, as it's possible to add libraries
(PLUGINLIBS, just as DRVLIBS), and it's possible to checks headers/libs
to activate a plugin (dvb/ppp/mysql for the moment, I must add wireless)
* one can choose the plugins he wants to avoid silly error messages
(think i2c_sensors Martin :) ) or reduce memory footprint.
* the configure stuff will be ready for dynamic loading ;)
* it's more professional ;)

Michael, check it and put it in CVS. And as usual, testing is welcomed !

Re: [Lcd4linux-devel] problems with CrystalFontz 634 v2.0 (CVS Version)

[Barry G. <mai...@pe...>]

Yeah, I think the startup delay should be a config option...

Also, I was looking at the little readme card that came with the display... 
apparently it can do things like display a factory logo or a custom logo on 
initialization, for 5 seconds.
It's supposed to reset itself if you send data during the 5 seconds, but 
mine doesn't.
Mine doesn't show a logo either.
There are apparently commands for re-programming some of these features in 
flashROM but I'd rather not mess with it, as I'm not sure what I'm doing, 
and it says if you overflow the buffer it'll hose the ROM.

Thanks,
Barry

Hi Javi,

Look great!

But I'd suggest some changes:

- move the plugin_init and _exit functions to the bottom of the plugin 
(so they are easier to find)

- move the call to getConfig() out of the init() function, into the data 
fetch function, but call it only once on the first turn, so the init() 
function does nothing but register the function (same as for the 
i2c_sensors plugin)

- rename the function from POP3check to Mailbox (??)

- use a slightly differen config layout:

Mailbox 'Private' {
    server 'localhost'
    port 110
    user 'me'
    pass 'dontknow'
}

Mailbox 'Business' {
    server 'mail.company.com'
    user 'me_again'
    pass 'forgotten'
}

  Widget Email {
      class 'Text'
      expression Mailbox('Private')
}

This way the #define MAX_NUM_ACCOUNTS 3 could go away...


- most important thing: make it asynchronous! Take a look at the 
plugin_exec. But beware: The code isn't that clean by now...

Well , I may think about it... Or even bvetter, you will provide a 
patch. And I want this stuff to be configurable :-)

That's what the evaluator is for. Just replace your
expression netdev(something)
with
expression (ln(netdev())
or
expression (log(netdev())

There's no need for scaling it afterwards, because here the auto-scale 
becomes handy :-)

Patches are welcome :-)
But I think this is already implemented.... autoscale is only used if no 
min/max values are specified... because there are cases where autoscale 
doesn't make too much sense (especially if the lower limit is not zero, 
e.g. a temperature sensor)

it's in widget_bar.c, function widget_bar_update()

Right. I removed it, because I had no idea what this is for. But as 
another user wrote, it works for him, and it works for mee, too. So 
something must be wrong with your display....

anyway, we should make this a config option, because 5 seconds are quite

This is because the config layout changed (now you have "structure" in 
the config file).

but the -c option still works, you just have to know how the structure 
is "flattened" (this should be documentet someday. Are the Doc guys 
listening?)

key 'val'
=> lcd4linux -c key='val'

group {
   key 'val'
}
=> -c group.key='val'

group 'name' {
    key 'val'
}
=> -c group:name.key='val'

group1 'name1' {
   group2 'name2' {
     key 'val'
   }
}
=> -c group1:name1.group2:name2.key='val'

No, I've a better idea:just move this initialisatin stuff into the 
data-fetch function, and execute it on the first call only. This way the 
plugin_init() function does nothing but register the plugin.

Same goes for all other plugins! (Nico? are you listening?)

[Lcd4linux-devel] NetGraph code

[Barry G. <mai...@pe...>]

Hi, I'm using LCD4Linux (from CVS) on my firewall, and enjoy the network 
graphs on my CF 634.

However, I notice the graphs will auto-scale to larger speeds, but then 
they never scale back down.

e.g.:
starting out, I have 0kbps traffic

I generate 2KBps traffic, and the graphs work great.

Then,
I generate 5MBps traffic (FTP transfer over 100Mbps ethernet), and they 
still work (all the way to the right).

After that,
nothing less than about 150KBps will register on the graph at all, unless I 
restart LCD4Linux.


Desired behavior(s):

1. Auto-downscaling. e.g. decrement the max over time so the graphs 
auto-shrink in scale, so smaller rates begin showing up on the graph again.


2. I have a 3com OfficeConnect 10/100 hub which has (roughly) a logarithmic 
utilization scale:
0.1 - 1.0%      2%      3%      6%      12%     25%     50%     80%
I think it would be helpful if the netgraphs could be scaled this way.


3. My internet connection is a cable modem... 3000kbps IN, 256kbps OUT; I'd 
like the outgoing part of the graph to scale correctly to 256kbps... 
perhaps that could be a configuration specification, or maybe it could be 
achieved though auto shrinking too.


I'm willing to work on at least 1 & 2 myself, however I haven't been able 
to figure out where in the code the scaling or tracking of the max values 
is being done.
Can someone fill me in on this?


Thanks,
Barry Gould

Hi.

If you have MySQL installed, you can compile lcd4linux with MySQL support b=
y that way:
#./configure
#make

[make will fail:
edit Makefile and replace
CC =3D gcc=20
in favour of
CC =3D gcc -lmysqlclient
save Makefile]

#make

[if make fails again, repeat:
edit Makefile and replace
CC =3D gcc=20
in favour of
CC =3D gcc -lmysqlclient
save Makefile]

Hope tha it helps.

Javi.

Hi,

Really? I have a 634 v2.0, it works for me, but i agree the scrolling
text of the kernel uname('machine') bla bla bla is scrolling too fast.
What i did was set the line "speed 500" so it scrolls much slower.

Not sure about the Curses and PNG displays and etc..

Best Regards,

~Alex

Hi Xavier, Thanks for responding.

I'm not sure what you are saying to do, but I'll try removing the mysql 
headers and compiling again.

(I already tried commenting the mysql driver out of Makefile.am, but then 
it got errors on plugins.c or something like that.)

OK, looks like it compiles now (without the mysql headers installed).

Thanks,
Barry

[Lcd4linux-devel] My light POP3 plugin

[Javi <ja...@gs...>]

Hi all.

While the official e-mail plugin is been ported to N.G, I've wrote my own simple mail plugin, based on the "pop3check" code from  http://sourceforge.net/projects/pop3check.
It only supports POP3, but I've spent more time writing it than I spent writing MySQL's one :0 

For it to work, I just added to my lcd4linux.conf:
Plugin mail{
        server1 ''foo.server1.com
        user1 'foo1'
        password1 'secret1'
        #port is optional, if none specified 110 will be used
	port1 110

        server2 ''foo.server2.com
        user2 'foo2'
        password2 'secret2'
	port2 110
	
	#etc...
}

#To get Account1 num. of mails:
Widget Email {
    class 'Text'
    expression getMail(1)
    prefix 'mail'
    width 8
    precision 0
    align 'R'
    update minute
}

POP3 accounts are stored dinamically, so you can use as much accounts as you want, just edit source code and change "#define MAX_NUM_ACCOUNTS 3"
Hope it helps someone till official pluging will be released :)

B.R

Javi.

Hi Alex, hi all.

Well, I'm not the most indicated person to answer because I only participat=
e in the MySQL plugin since few weeks ago,
 but you should know the CVS version (aka "Next Generation") has been rewro=
ted from scratch (correct me if I'm wrong) so
it is relatively recent, and may be, there are lots of features that have n=
ot been ported yet.

[Lcd4linux-devel] Command line -c arguments

Hi,

I just tried out the CVS since another user were asking about the mysql
plugin, and it seems nice because the bars display for the CrystalFontz
now works properly. However, I used to do lcd4linux -q -c Backlight=0 -c
Contrast=0 to clear the screen on my lcd4linux shutdown script on gentoo
linux. It seems the CVS doesn't work anymore with -c Blacklight=0 and etc...
I do however have a work around which is to do "-f another.conf" so that
in that "another.conf" file i would set the display ... { Contrast=0 and
Backlight=0 } But it'd be nice if the command line option works properly
or maybe the format of [-c key=val] changed on he CVS and I don't know
how to use it. ^^! Just wondering if anyone have any info on this, or
maybe i missed similar post(s) on the mailing list archive ... couldn't
find info on the new format if there is a new format that is ~~. I know
the Clear() function isn't implemented yet as mentioned by someone else
earlier. But just wondering if anything happened with the command line
options.
