Re: Welcome to the "dia-list" mailing list (Digest mode)

[fitorec]

I am fitorec, I am interested in develop a Dia-Python-Plugin for a dump sql
. I wrote the following code:

import sys, dia

class SqlRenderer :
def __init__ (self) :
self.f = None

def _open(self, filename) :
self.f = open(filename, "w")

def begin_render (self, data, filename) :
self._open (filename)
self.f.write('''-- DiaSql-Dump
-- version 0.01
--
''')
for layer in data.layers :
for o in layer.objects :
#types which are valid??
if o.type.name == "DATABASE - Class" :

def end_render (self) :
self.f.write('-- end Dump')
self.f.close()

dia.register_export ("SQL plain", "sql", SqlRenderer())

General problems that I had not know the models, their properties and
methods of DIA, I would like to see if they can send me some information API
--A plugin that works the Database Diagrams greatly help me--.

 I read the documentation  http://live.gnome.org/Dia/Python but, I did not
find any reference that could help.

thanks in advance.

PS sorry my english is very bad.

Suggestion - a Web forum

[one_elengr]

Hello,

I wonder if anyone would be able to set up a Web forum for the same 
purpose as this mailing list.  Other open-source software projects 
have forums, and I find that to be a much more convenient way to 
browse discussions than a mailing list.  

Forums normally allow all new messages to be e-mailed automatically 
to subscribers who so choose, so that people can still get the 
discussion traffic in their e-mail inbox if they prefer.

After spending a sleepless night I make the head of the table definition,
what I could do was the same body.

Please if anyone knows how to do this or have an idea for answer.

python code:

import dia, sys, os, string

class MySqlRenderer :

self.f = None
# the bintmap exporters calculate their ow margins from the bunding
box

def begin_render (self, data, filename) :

self.f.write ("-- DiaSql-Dump\n-- version 0.01\n--Filename: %s\n" %

for layer in data.layers :
self.WriteTables (layer)

def WriteTables (self, layer) :
for o in layer.objects :
r = o.bounding_box
if o.properties.has_key ("name") :
url = o.properties["name"].value
elif o.properties.has_key ("text") :
url = o.properties["text"].value.text
else :
continue
if len(url) == 0 or string.find (url, " ") >= 0 :

self.f.write ('\t\t...\n')

Object alignment does behave as expected

[Jon Oesterheld]

I was working with some objects; The command organ of relay (horizontal)
and Horizontally aligned diode, and I noticed that when using the
Objects, Align, Top, Middle or Bottom the two objects are not positioned
where I would expect them to be. When using the Align, Left, Center or
Right they seem to work correctly.

 

So I tried the same test with the vertical versions of the relay and
diode and now the problem is with the Left, Center and Right alignments
and the Top, Middle and Bottom seem to work OK.

 

I am only a user not a developer so is it possible that this would be
fixed in a future version of Dia? I like how quickly I can create a
diagram using Dia but having to mess around with the alignment to make
it presentable eats up a lot of time. This is also an issue addressed in
my other post about the objects snapping to the grid.

Re: Suggestion - a Web forum

[Steffen Macke]

Hi,

we definitely need a a forum for all them flamewars :-)
Jokes aside: A forum needs to be maintained and moderated,
plus it needs a sufficiently vibrant community.

A while ago, I had a "Dia forum" enabled as part of the dia-installer
Sourceforge project:

http://sourceforge.net/projects/dia-installer/

I switched it off because I ended up doing all the moderation and
answering all the questions.
It's not running the software, you need a sufficiently vibrant community.

Did you look at Dia's Facebook page:

http://www.facebook.com/diagramr

It's nothing else than a forum (Please don't start a Facebook flamewar now).

But all that shouldn't keep you or others from setting up and
maintaining a Dia forum.
Please announce it here on the mailing list if you do so.

Regards,

Steffen

Re: Suggestion - a Web forum

[Michael Ross]

Of course I have been in this forum for years (and other very safe - text
based mailing lists), I will state forthwith that I like this list the way
it is.  Maybe it is like an old shoe - no new one can quite compare.  It
requires a minimum of effort to review the messages and reply.  Having run
lists like it, I know that this format minimizes administrative duties, a
very good thing when time resources are short.  The time to set this list up
is a sunk cost, not recurring.

It is true that searching for past information is less easy, but honestly
the older messages won't reflect the subsequent good work that has gone on,
and fewer people than you might think ever do search archives.

Anyway, I wouldn't do it.  And wouldn't like having to use another forum.

That's up to Hans to answer.
Looking back and considering that some people like to see a somewhat
fixed release schedule, I would say that Dia is roughly on a one release
every year scheme (And the last release happened in January).

This depends on the number of interesting features added:
  http://git.gnome.org/browse/dia/log/
the number of open bugs:
  https://bugzilla.gnome.org/browse.cgi?product=dia
and/or closed bugs:
  http://bugzilla.gnome.org/buglist.cgi?product=dia&target_milestone=0.98

And of course it also depends on the availability of a big enough time slot 
to actually do a release ;)


BTW: patches accepted.

I played a little with these shapes and the only "unusual" behaviour I
could detect was with the relay (horizontal) from the Electric sheet. Do
you also have problems with other shapes? If yes,
please describe them in as much detail as possible. But please do not
report shapes that work
correctly.

Unfortunately, we cannot just change the behaviour of the relay
(horizontal) shape, because that would break backwards compatibility.
But it should be possible to provide an alternative horizontal relay
that behaves the way you expect it.
For the time being - as a workaround - you can simply group a rectangle
and a line into a relay shape of your own. You can copy and paste this
group like a shape. See the Dia manual for information
about grouping and ungrouping objects. If that works out for you, you
could try to create your own
shape(s): Just follow the step-by-step instructions

http://dia-installer.de/howto/create_shape/index.html.en

I don't think you have to be a developer in order to do this.

Steffen

I don't expect that you'll hit a hard limit, but things will get slow
and you'll have problems obtaining a meaningful diagram layout.

Which programming language do you use? Besides the Dia C sources,
there's a couple of other programs available that are capable of
producing Dia files:

Maybe one of them matches your needs.
As you seem to be dealing with a fairly huge number of objects: Have you
thought about a program like GraphViz that specializes on the automatic
layout. Graphviz is able to output Dia files.

Re: Adding a Minus-Sign to an Arrowhead

Hi Steffen, Hi Hans,

Yes, but how to get rid of its border? (I use for example "perfect sqare")

Ok, this sounds god. So I let my text snap to a box, which itself will snap to 
the arrow heads.

Absolutely right. I guess, this is what I am going to to.

Hm. Yes, this works. But unfortunately not with zigzag-line.

Which lines would that be from the UML-Sheet? I could not find out.


Thank you very much

Thats right. I installed Mac Ports and changed the source code.

How can I restrict the following command

"sudo port install "

to compile the dia-sources located on my machine instead of downloading the 
tar-ball from a server?

RE: Object alignment does behave as expected

[Jon Oesterheld]

OK so far what I've found is that any vertically aligned shape from the
'Electric' sheet will not properly align with any vertically aligned
shape from the 'Circuit' sheet.

Run this test: open a new diagram, drop a 'Vertically aligned capacitor'
from the 'Circuit' sheet onto the diagram. Now drop a 'Relay (vertical)'
from the 'Electric' sheet onto the diagram. Select both objects and then
align them to 'Center', they aren't even close.

It appears that all of the shapes in the 'Electric' sheet work fine with
each other, and that all of the shapes from the 'Circuit' sheet work
fine together. The problem arises when you use shapes from different
sheets. I have only looked at these two sheets but I will check others
to see if the same problem exists.

I'm guessing that these two sheets of shapes were created by different
people and something in the way they were created is causing this
mismatch. That is why I asked in a previous post if there were some
instructions or guidelines on how to create shapes. I have created one
shape and it will align properly with the shapes from the 'Circuit'
sheet but not the ones from the 'Electric' sheet.

 
Kind Regards,
 
Jon

I played a little with these shapes and the only "unusual" behaviour I
could detect was with the relay (horizontal) from the Electric sheet. Do
you also have problems with other shapes? If yes,
please describe them in as much detail as possible. But please do not
report shapes that work
correctly.

Unfortunately, we cannot just change the behaviour of the relay
(horizontal) shape, because that would break backwards compatibility.
But it should be possible to provide an alternative horizontal relay
that behaves the way you expect it.
For the time being - as a workaround - you can simply group a rectangle
and a line into a relay shape of your own. You can copy and paste this
group like a shape. See the Dia manual for information
about grouping and ungrouping objects. If that works out for you, you
could try to create your own
shape(s): Just follow the step-by-step instructions

http://dia-installer.de/howto/create_shape/index.html.en

I don't think you have to be a developer in order to do this.

Regards,

Steffen
