This is a great idea. My window manager, i3, works very well with a
feature like this. Sadly a lot of actions are application specific and
require that specific application to support "hinting" (to work with a
general solution) or to implement their own solution.

You may want to look at https://pwmt.org/projects/girara/, which
provides a vim-like input for an application. It finds use in Zathura
(PDF reader) and Jumanji (browser, not usable iirc).

Re: [Lazarus] Building a C (or possibly C++) program into a Lazarus app

[R0b0t1 via Lazarus]

I have some posts on the forum asking about similar questions. I was
told FPC object files will link just fine with GNU tools, so you
should be able to.

To me it seemed it would be easier to keep the codebase in C++ but
then call into the LCL. Sadly that is quite a bit off.

My apologies, I was a bit confused. Mr. Breneman mentioned compiling
for Android from Android in one of his posts. If you really wanted to
do that, following the steps on that page is probably the easiest way
to accomplish it. Though now I think there are some other
distro-unpackers that will run on unrooted phones. Gentoo is probably
the best and has the most up-to-date software.

If you mean to go from x86[_64] -> Android then I am very interested
in the answer to this question. At most I found
http://wiki.lazarus.freepascal.org/Android_tutorial some time ago.

How well did those studies account for potentially incomparable
workflows? I think I agree with what I think to be their conclusion -
if you have two similar workflows, graphical navigation may be faster,
because it is easier to guide thought with.

But what if I can skip all of the intermediate steps and go straight
to the action? Lots of CLI interfaces especially are domain specific
languages, and the actions can be encoded into key combinations.

To further clarify in the case of Wine, reverse engineering for

I would be extremely thankful if anyone had the time to at least start
on this. One of my main complains with Lazarus/FPC is that it is IDE
centric. The IDE is not that bad, but it is kind of hard to integrate
into my normal desktop (a tiling window manager).

Bad:

2) I can't view videos, but this may be me.
3) The popover for viewing file content could be replaced with opening
a browser window (usually a tab).
4) Not as shiny as some web services.

Good:

I doubt that in general a program exists to do what you want, as it
would require having a front end for the C language and then something
close to a decompiler for Pascal.

However, this thread did clue me in to h2pas, which I hope can be used
to convert STM's header files for the embedded target project.

It will not happen again, sir. I am a stain upon this mailing list.

My question was not about UTF-8 support in Lazarus. I know it works.
My question was about interoperability with Windows. Theoretically
there are some serious issues; I figured I would get a better response
asking someone using UTF-8 with Windows compared to a general poll.

The combination of those is the largest part of why
http://utf8everywhere.org/ and many independent developers recommend
avoiding Window's implementation of UTF-8. It doesn't end up doing you
any good, because you typically can not set the whole system to use
UTF-8 (because it is broken).

The brokenness (described at
https://social.msdn.microsoft.com/Forums/vstudio/en-US/e4b91f49-6f60-4ffe-887a-e18e39250905/possible-bugs-in-writefile-and-crt-unicode-issues?forum=vcgeneral)
is due to the UTF-8 codepage causing Windows to report multibyte
characters as a single character, and stdio assuming one byte per
character.

The Chinese/Japanese mappings apparently had these problems as well,
but a workaround was added.

I agree, and am glad to find this was brought up. On the other hand, I
think it would be good to know what is going on in the event loop of
the application. There are some inconsistencies in naming and how
threading "works" or does not work that I am still baffled by. This is
likely not a Lazarus issue, and may be something inherited from
Delphi.

I think the goal could be aided with a high level document on what is
going on, as I've had it explained to me a number of times but am
still confused.

I've been looking for a replacement to

dealbreaker is the library's codebase making heavy use of anonymous
functions and procedures.

Does System.Threading expose an API that could take either code

Re: [Lazarus] Windows touch input

Hello friend,

2018-01-21 13:36 GMT-06:00 AlexeyT via Lazarus :
> How does Laz support touch input [e.g. on Surface from MS]. Where to read
> about it in wiki?
>

For most input, touch events are turned into mouse events. The most
basic events are WM_GESTURE[1] (received by default) and WM_TOUCH[2]
(opt-in) messages. WM_TOUCH will receive pen events. You may also
access these events using raw input and the WM_INPUT message, though
details on this are not as forthcoming.

However, from Windows 8 onward, there is a pointer API which unifies
pointer (generic), touch, pen, mouse, and touchpad input. Look at the
WM_POINTER*[3] messages for more details. The most control is granted
with this API, and you can, for example, get the pressure of the pen
on the screen as well as its pitch, roll, and yaw relative to the
screen.

You might also be interested in stylus/pen input, but it is much more
complicated.[4] If you wish to use another writing recognition
library, or do not need one, then you should be able to access these
events via WM_TOUCH, WM_POINTER*, or WM_INPUT. There is also a COM
object called a RealTimeStylus.[5]

The package mlocate contains the locate and updatedb commands, and
produces quick results.

I typically use find with grep, though that may be slower. But I have
more control of the results.

To be clear, for some reason most of the time the unit (and every

I think this may be a bug, but I do not think it has to do with
generics or packages. I encountered a very similar issue with a
project I help maintain, where I fixed some issue in a unit but that
unit was not automatically recompiled after being changed. I had to
clean and rebuild the project. As you say, this is not extremely
expedient.

My apologies for not keeping more details, but I was quite happy to
have gotten it working at the time.

I realize now you were asking to disable theming in Lazarus. That answer is
related to the contents of my other posts, but for GTK you may use the
environment variable GTK_THEME:
https://developer.gnome.org/gtk3/stable/gtk-running.html.

GTK_THEME=theme:variant

If you have some time I would invite you to comment on the forum as it is
more active. It would be nice to see pictures of the interface quirks you
take exception to.

Theming is typically handled by your toolkit. For GTK, you will need to
modify files in a location like "~/.themes" or "~/.gtkrc-2."

E.g. https://developer.gnome.org/gtk3/stable/theming.html and
https://wiki.archlinux.org/index.php/GTK%2B#Configuration.

Theming can also be handled by your application. The best support for
theming tends to be implemented in this way. Unfortunately from a user's
standpoint this means each program must be customized separately. On the
other hand, toolkit wide theming support tends to not be very good. Form
components (like a SynEdit) may be drawn with colors not taken from the
toolkit's configuration.

Theming support for Lazarus might be a tall order but I think it would be
worth it. See Visual Studio's dark theme, for example.

This is something else I forgot to touch on in my dimwittedness.

My experience with a multi-user project (Simba) that targeted Windows/Linux
was very poor. It was hard to keep the project in a state that made it
buildable on both OSes or even multiple. Eventually these issues were
overcome, but there still seems to be a lot of hidden complexity that makes
it hard to create reproducible builds and help new developers set up an
evironment.

I think this really captures what I wanted to say. Rapid development as a
design methodology seems to have been publicly discredited and forgotten
about, yet people still continue to buy Delphi. The basic design principles
that FreePascal and Lazarus implement are still relevant but the
presentation is a little rough around the edges.

Hello,

I work with a project (Simba: http://wizzup.org/simba/) that was
written in FreePascal using Lazarus. One of the main issues with Simba
was the necessity of creating wrappers for most of what needed to be
accomplished. On a more personal note, I find Lazarus very useful for
quick GUI prototypes, but the lack of supporting infrastructure makes
it hard to use sometimes.

I appreciate the development that does take place and wish more could.
I have tried to find ways to help off and on, but all the problems
that are left are very involved.

A more impressive contribution to the list was planned but I forgot
what I was going to write. However, if you wanted to know if what you
do is useful, then yes, I think it is.

Cheers,
 R0b0t1.

Hello,

I am not very smart nor clever and I did not find this documentation.
Could you link to it? This is the best explanation for the weirdness I

I read about the OpenGL ES hack to allow X11 compositing(?) but never
anything about configuration.

Thank you for clarifying - I wasn't sure if the OP was also talking
about an issue with the code editor. However, I think inclusion of
fonts in the LCL might make sense if it is found that system fonts are
lacking for popular platforms.

The LCL is (to my knowledge) linked in to applications generated with
Lazarus and never installed separately. Some toolkits for other
languages, installed separately, ship with (optional) resource files.
Compiling in the resources to every program which uses the LCL is a
bit different, but the same principle.

It is not necessary to rely on only the system font collection, even
when using WinAPI forms:
https://msdn.microsoft.com/en-us/library/system.drawing.text.privatefontcollection.aspx.
Something similar is done in C++.

Admittedly there does seem to be some confusion about whether you can
make certain UI objects (non-GDI+, specifically) take on face of these
fonts, but I suspect you can, as it seems that there is a common
underlying graphics system that the old APIs use. Even if not it would
be possible to distribute an open font with Lazarus/the LCL and
install it when Lazarus/the LCL is installed.

Is it not possible to bundle supported resources in the LCL? That seems
like the typical solution for Windows. On other OSes this is less proper,
but I have still seen it done.

Re: [Lazarus] Accessibility enhacement request Lazarus version 1.7

[R0b0t1 via Lazarus]

Sorry about the delay. I'm not sure I can help directly.

You may want to ask on the forums. Now the problem has been expressed in
terms that someone can use to create goals.

The complexity of adding accessibility hints to custom GUI work is what led
me to suggest an external editing program. Do you know how the Lazarus GUI
functions (code hints, etc), and can you describe an analogue of that
functionality that could work for you?

Cheers,

I can agree, I have seen very impressively formatted documents done in
LibreOffice/OpenOffice/Microsoft Word. At the same time, the majority
of technical documents seem to be meant for screen-based consumption.
In that case the viewing options for the listed formats can be less
attractive than they otherwise might be.

I would suggest using Sphinx, http://www.sphinx-doc.org/en/stable/,
the software package that Python uses to generate its documentation.
It can be adapted to other languages and I worked with a project that
uses it with an Object Pascal codebase.

With most software packages in this vein, the possibility of
generating images that are rendered from LaTeX exists. However, you
need an installation of the same to do this.

If the LCL handles asset selection for you, yes. But I don't remember
seeing that - you may need to select the appropriate icon at runtime
yourself.

Hello Mr. Chmiel,

I have some minor experience working with the visually impaired (usually
not complete blindness). Can you describe the operating system you use and
how you make use of your screen reader for editing? Most readers will not
be familiar with such things.

In the interim, you may want to use another editor for your programming. I
do this myself occasionally but recognize that the Lazarus editor has
better integration with the design workflow.

Cheers,

You can think of an object's data as a monad's data, and the methods
in the objects in a hierarchy as the various monadic functions which
operate on that data.

In a typical functional language the monadic functions and their
arguments do not have any hierarchical relation.

The forums are far more active, and the developers seem to be fairly

Hello,

If such comments are not unwelcome I would also suggest there are many
architectural improvements in the code and invite Mr. Canneyt to
peruse the Plasma 5 source (KDE 5 doesn't exist).

That said there are some changes that have broken UI compatibility
with KDE 4 and made the menus slightly harder to use for people with
poor eyesight, but many things have similar problems.
