Re: GSoC project to add CPDB support to the LibreOffice print dialog

[Biswadeep Purkayastha]

Monthly update: July 2024

Hello everyone,
Last month, I focused on rewriting older code to incorporate CPDB frontend API 
functions and fix the printing process. Now, printing with CPDB works 
seamlessly on the LibreOffice print dialog. During this process, I discovered 
that the printer names in the LibreOffice dialog are static and evaluated at 
startup, unlike CPDB, which periodically refreshes the printer list. 
Consequently, the print dialog had to handle situations where a printer might 
no longer be available even though it is still displayed. I implemented changes 
for dynamically updating the printer lists and to include appropriate error 
handling to address this issue of stale printers while using CPDB. 
Additionally, I modified the functionality of the "Print Directly" button in 
LibreOffice so that with CPDB it now prints to the default printer initially, 
rather than the first available printer as it did previously.

Regards,
Biswadeep

Re: GSoC Project: Sidebar deck for quick find

[Heiko Tietze]

Hi Siddharth,

happy to see your interest in LibreOffice, and in particular in UI topics :-).

Not sure Jim reads the mailing list but I do. He would be the code mentor while 
my contribution could be to test the implementation and to recommend UI solutions.


Jim already created a simple prototype to see how much effort there might be. So 
if the project has any blockers I'd expect it on the UI/UX side. Meaning some 
complexity with replacement functionality (personally, I'd would keep things 
simple and not abuse the sidebar as dialog replacement). Some discussion has 
been done on the ticket.


As always, we request students to proof skills by solving easy hacks. Ask in 
private, if you don't find an appropriate ticket.


Looking forward to work with you,
Heiko

Hello,

I was recently taking a look again at the GSoC ideas list and I found out that 
it had been updated a bit since I last took a look at it a couple of weeks ago. 
I, unfortunately, wasn't able to find a mentor to help me with the previous idea 
(Improving Zoner Draw Filter), and also couldn't find a copy of Zoner Draw 2 for 
testing, which I was researching to implement so I went to look at the list 
again for inspiration. Then, the idea to implement Quick Find as a sidebar deck 
interested me. As I researched the idea further, I read through the discussion 
and implementation regarding this idea at: 
https://bugs.documentfoundation.org/show_bug.cgi?id=95405 
. I also looked at 
the mock-up at: 
https://bug-attachments.documentfoundation.org/attachment.cgi?id=184862 
 & 
thought that it was pretty close to my view of the project as well. The 
implementation of the idea seems pretty doable for a beginner like me who is new 
to open-source development as a whole. In the meanwhile, I've looked into the 
files srchdlg.cxx and navigatorpanel.ui for an initial idea of the 
implementation of the project.


I think the ideal implementation of this idea would be to -
1) Create an additional find/replace section in sidebar
2) Leave the current find/replace dialogue in place (for the sake of user 
choice)
3) Show multiple matches of the searched keyword from the content in the sidebar 
and highlight them alongside with a yellow font color in the file, also allowing 
the user to cycle through them with a button click


Firstly (and most importantly), Are there please any potential mentors who are 
willing to help me with this project? The GSoC ideas page mentioned potential 
mentors as /Jim Raykowski and //Heiko Tietze, /can somebody please contact them 
and ask if they're interested in this project?

Are there any foreseeable roadblocks or challenges to the execution of this 
idea?
In which area should I start focusing my research to start working on the 
document to successfully implement this idea as part of GSoC 2023?
Is anyone else currently aiming to implement this idea at LibreOffice or in the 
LibreOffice open-source community?
Lastly, are there any other tips or thoughts regarding this that you would like 
to give me?


Thanking for your time and consideration,
Siddharth K

For this Google Summer of Code, I would like to contribute to the

I request you to review this draft and give your valuable feedback.


It's wonderful that you want to take care of multi-color gradients. It's 
a complex issue. The members here on the mailing list have very 
different knowledge and skills. So don't hesitate to ask here on the 
list and maybe learn about completely different aspects.


For example, I work with the ODF file format. From this point of view 
you should know that the ODF file format has two completely different 
gradients [1].
One is the gradient defined by the element . It is 
implemented in LibreOffice, and the user interface belongs to this 
gradient. It allows only two colors, but has very different shapes of 
the gradient.
The other one is the gradient defined by the elements 
 and . It allows multiple 
colors, but is not implemented yet.


For all solutions, not only internal handling and user interface have to 
be considered, but also how the style information can be stored in the file.


I wish you every success in your work.

Kind regards

Whoopee!

Please let me offer some random thoughts.

I have often been unsure what I did to provoke LO to misbehave:
sometimes my attention was absorbed by actual work I was doing,
sometimes I had given up trying carefully to reproduce a bug report
only to see the bug come up later.  So it would be good if the logging
is cheap enough to use routinely during regular work.

For a couple of reasons, I expect that the log file will not replace
the STR in a bug report: (1) The log file will contain irrelevant
operations, everything from a slip-of-the-fingers corrected promptly
to completely different tasks imposed on the user during the LO
session.  Determination of just which operations are relevant may be
tedious, but confidence that the misbehaviour can be reproduced will
justify much more effort than would mere knowledge that LO misbehaved
once.  (2) Part of the QA process for bug reports involves testing
older LO versions.

From this, I conclude that it is important that the log file be
decipherable.  Indeed, for the preparation of bug reports, the
automated playback is mostly important for proving that the bug is
reproducible, thus motivating the decipherment of the log file.  So,
an easily readable log file is better than one which is hard to read,
but the difference is less important than one might guess.

If the log file is not easily readable, then we would eventually want
a program to express it in user-level terms.  As a hack, this program
might not be quite "easy", but it could be undertaken so that it would
not hold up other work.  Perhaps it could be so specified that
language-level programming knowledge (as opposed to knowledge of LO)
would be sufficient for the task.

Thank you, Saurav, for undertaking this work.  Is there a place where
we can follow your progress?

Terry.

Your first step should be to build LibreOffice and then its Online component.
And then open a document and being able to see it reflected in the admin
console. There's some information here that might be useful to you, if you
haven't already built and run Online.

https://wiki.documentfoundation.org/Development/LibreOffice_Online

Please don't hesitate to ask further. You can either hang out on
#libreoffice-dev on freenode or ask questions on our mailing list (CCed). Happy
to help you cross that first hurdle :)

I would suggest you to first start looking at some of the easy hacks (look for
the link above) - after buildling Online successfully - to get your hands dirty
with the relevant code. It's also important for us to be able to consider you
for GSoC.

Resurrecting the history view is one of the tasks in the 'Online Admin' project
and it's one of the least prioritized tasks. We would want to make you work on
new features instead. So, all the points above the history view on the wiki page
you saw are the ones that should be on your radar. Please play a little with the
admin console first to be able to get a more clear idea of what exactly those
tasks are. Happy to answer any specific questions thereafter that comes to your
mind :)

We get the same SVG quality as we currently get rendering embedded SVG

Glyph layers either use a specific color or text color but not
both, the choice is encoded in the COLR table.

As a qualification process, we require students to work on at least one Easy
Hacks (as mentioned here[1]) before you submit your application for GSoC later.

Please look at the list of easy hacks for Online[2]. There are relevant code
pointers already in all of the easy hacks but if stuck, don't hesitate to ask on
the bug itself. There is some more helpful information on the same wiki page
including slides of talks given on LibreOffice Online in previous conferences;
you might want to go through them to understand the architecture, code
structure, etc.

That's great to hear.

the gen X11 backend is useful as a fail-safe fallback when the other
ones don't work; i've got bad experiences running some of the bibisect
repos on Fedora 27 where gen is the only one that doesn't crash on
startup, and i guess one of the reasons for that is that ~nobody does
changes in gen or the system's X11 libs nowadays.

so i'm mostly interested in preserving gen as-is and not adding fancy
new stuff with unknown compatibility issues to it...

I have added the idea to improve OpenGL backend, which I'm also
willing to mentor. For GTK3 - Caolan is the right guy who knows what
could be improved there performance wise. But OTOH any X11 are
probably pointless as the idea AFAIK is to get rid of those backends
in the long run, so I'm not sure who would even be interested in
mentoring that. :)

Sure, absolutely!

Just please, before adding projects to that wiki page, please find a
sponsor/mentor from the core devs for that.

For that gfx stuff, Tomaž, Michael Meeks, or Caolan come to mind
(perhaps yours truly as fallback).

Cheers,

In particular I wonder what subtickets of tdf#106547 are fixed now and how
the design team can improve the situation on tdf#99563.
