Hello,

Has anyone dealt, and succeeded, in interfacing Tcl with UBL** format using current extensions or
packages such an xlm parser ?

Thanks, Olivier.

** UBL is the acronym for Universal Business Language, it becomes mandatory
to use it to emit and receive invoices in B2B in some countries. It is xlm formated.

Alexander Schöpe has done some work here and embedded an elecronic
invoice in two formats into a PDF.

I am probably very blind.

Buttons with multiple text lines:

pack [button .b2 -justify center -text ABC\nD]

may use the -justify option to center the lines.

Now ttk:
pack [ttk::button .b2 -justify center -text ABC\nD]

no option justify

ttk::style configure custom.Toolbutton -anchor center -justify center
pack [ttk::button .b -style custom.Toolbutton -text centered\n2]

no effect.

Is there a way to center the text?

This is Style Vista on MS-Windows...

Thanks for any idea,
Harald

I was aware of tclpdf improvements, but I did not see there was invoicing included.
It uses Factur-X format, which is in fact pdf + xlm in one document.
UBL is simpler as it uses only xlm. But the structure of tclpdf, is interesting as a tool to manage a lot of things : proposal, specifications, invoices...
I will have a look and see how it works.

Thank you,

Olivier

You are welcome. By the way in thread "Why I'm reverting from Tcl/Tk 9.1.0 to Tcl/Tk 9.0.3",

it seems to have a clue for theproblem you encountered :

"There are other blocking known bugs in 9.1.0 like the non-functioning "-justify" in ttk widgets."

Harald, your statements regarding the ttk::button widget are not
correct. The following works for me as expected with the vista theme,
with both Tk 9.0 and 9.1:

# ttk::button has no -anchor option but supports the -justify option.
pack [ttk::button .b2 -justify center -text ABC\nD]

# The custom.Toolbutton style supports the -anchor option.
ttk::style configure custom.Toolbutton -anchor center
pack [ttk::button .b -style custom.Toolbutton -justify center -text centered\n2]

Note that here we combine the -anchor *styling* option with the -justify *widget* option. With Tk 9.1 there is also a -justify *styling* option,
hence the 2nd block above can be replaced with:

# The custom.Toolbutton style supports the -anchor and -justify options. ttk::style configure custom.Toolbutton -anchor center -justify center
pack [ttk::button .b -style custom.Toolbutton -text centered\n2]

Hi Olivier,

For XML in Tcl, tDOM is the first choice. It handles namespaced XML
such as UBL well, both for parsing (XPath via selectNodes) and for
generating documents.

If you also need hybrid invoices: my package tclpdf supports embedding
XML files into PDF/A in a standards-compliant way, e.g. ZUGFeRD /
Factur-X. https://fossil.sowaswie.de/tclpdf/wiki?name=examples

Hm, I did not want to take time from others as UBL is a fairly complex format : https://docs.oasis-open.org/ubl/os-UBL-2.1/UBL-2.1.html

I am interested to know if anyone has already edited such xlm document with standard extension or package, to try to replicate his/her approach and not reinvent

Thank you, I will take more than a look !! The paradox is that the UBL
format is easier to handle than pdf , since it is only text, but accountants are proposing layer of layer of tools, sometimes AI, and this makes
me nervous about it. Factur-X could very useful for firms outside Europe,
or consumers in France.

tDom (https://www.tdom.org/index.html/dir?ci=521ed5326479ed83) is an
excellent extension for the handling/editing/creating of XML data.
However it is a compiled extension so if you must have "pure Tcl" it
won't match that requirement.

Just be forwarned if you do go the "do it yourself" approach. XML
appears simple on its face, but the totality of the spec. is anything
but simple. Handling all the spec. compliant edge conditions is a lot
of effort.

Thanks. I didn't have time at the moment so some basic cursory info
would have been helpful. I did look it up during lunch. I found these
sites which you may be familiar with already: https://peppol.org/ and https://e-invoice.be/blog/ubl-format-guide#document-structure

I have a tool that makes these operations quite easy. Unfortunately it
is not a package or something that can be ripped out easily.

BTW, you keep typing "xlm" vs. "xml". A typo or are we all missing
something?

I agree, and in that case I will approach differently than using forms, but editing a validated template and changing the content inside a
<tag></tag> couple, but, yes, I am afraid that the "compliant edge conditions is a lot
of effort." if this tag is not unique.

The TButton and Toolbutton styles have always supported the -justify
styling option. Unfortunately, the vista theme ignored it in Tk
versions 9.0.x (this was probably due to a bug). OTOH, most (or even
all?) other built-in themes have always honored this option, and so did,
e.g., awlight, awdark, and droid.

Hence the answer to your question is: On AndroWish just use the
-justify styling option.

This was never documented. I propose to document it.
Is there a rationale why the command option -justify was added in Tk9.0?

Tk 8.6: ok, 9.0: no, 9.1: ok

pack [ttk::button .b -style custom.Toolbutton -text centered\n2 -justify center]

Tk 8.6: invalid option, 9.0: yes, 9.1: no effect

So, to resume:
- styling option, with Toolbutton: works except 9.0
- styling option with TButton: no effect at all
- command option: only effect in 9.0
I think, a bug ticket would be great...

Invoking "ttk::style configure custom.TButton ..." and then creating a
button of the *different* style custom.Toolbutton doesn't make much
sense! Make sure that the button has the same style!

So, the results are:

Does this sounds reasonable?

sense!  Make sure that the button has the same style!

Ok, next try, repeating the last three and correcting results:

T1) vista theme, toolbutton

ttk::style theme use vista
ttk::style configure custom.Toolbutton -anchor center -justify center
pack [ttk::button .b -style custom.Toolbutton -text centered\n2]

Tk 8.6: ok, 9.0: no, 9.1: ok

T2) alt theme, toolbutton

ttk::style theme use alt
update
ttk::style configure custom.Toolbutton -anchor center -justify center
pack [ttk::button .b -style custom.Toolbutton -text centered\n2]

Tk 8.6: ok, 9.0: no, 9.1: ok

T3) vista theme, button

ttk::style theme use vista
ttk::style configure custom.TButton -anchor center -justify center
pack [ttk::button .b -style custom.TButton -text centered\n2]

Tk 8.6: ok, 9.0: no, 9.1: ok

T4) alt theme, button

ttk::style theme use alt
update
ttk::style configure custom.TButton -anchor center -justify center
pack [ttk::button .b -style custom.TButton -text centered\n2]

Tk 8.6: ok, 9.0: no, 9.1: ok

T5) vista theme, button, command line option

ttk::style theme use vista
pack [ttk::button .b -text centered\n2 -justify center]

Tk 8.6: invalid option, 9.0: ok, 9.1: no effect

So, the results are:
-justify styling option: ok on 8.6 and 9.1, no effect on 9.0
-justify command option: ok on 9.0, no effect on 9.1

Does this sounds reasonable?

Thanks for all,
Harald

Yes, this looks much better. But note that the upcoming Tk versions
will improve some of these results, due to the many bugfixes of the last
few weeks. For example, the -justify widget option is no longer ignored
by the current trunk version of Tk 9.1, and the -justify styling option
is no longer ignored by Tk 9.0 built from the current core-9-0-branch.

Dear Csaba,
Thank you for all this! My personal issue is now solved.

Dear all:

The remaining points are:

- why is only the command line option documented and not the styling option?

- why was the command line option "-justify" added in 9.0, if there is a styling option? This makes IMHO little sense, if -anchor is only
available via styling... Or is -justify seen as part of the label text?
I think, this is the point.

Thanks for all,
Harald
