Meson issue with -L--export-dynamic flag
Myself and some others are looking at replacing autotools in Tilix with meson for the various Linux distros to use when building and packaging the binary. However we are running into an issue with meson around the use of the "-L--export-dynamic" flag. When compiling with meson using LDC and that flag the following errors are generated: [66/66] Linking target tilix.

Taking out the export-dynamic flag it all works fine.

That flag looks pretty innocuous so I'm not sure why it is causing an issue. I could use some help from someone more experienced with the compiler to help understand what is going on and if there is an issue with tilix, meson or the compiler itself.

Create variable for RedBlackTree range
What is the appropriate way to create a variable for the range
returned by RedBlackTree lowerBound and upperBound. For example,
given this code:
```
RedBlackTree!long promptPosition = redBlackTree!long();
long row = to!long(vte.getVadjustment().getValue());
RBRange!(RBNode!long*) range;
if (direction < 0) {
range = promptPosition.lowerBound(row);
if (range.empty) result = lower;
else result = range.back;
} else {
range = promptPosition.upperBound(row);
if (range.empty) result = upper;
else result = range.front();
}
if (result >= lower) {
vte.getVadjustment.setValue(to!double(result));
} else {
promptPosition.remove(range);
}
```
The second line where I declare the range variable as
RBRange!(RBNode!long*) the compiler complains with the following
warning:
Deprecation: std.container.rbtree.RBRange(N) is not visible from
module terminal
Which makes sense since RBRange is a private struct. However I
cannot use the normal range interfaces here either (ForwardRange,
BiDirectionalRange, etc) since it complains about RBRange not
being able to cast to them.
Re: DUB and Gtk-d reduce size of huge executable, build dynamic dependencies
On Wednesday, 7 March 2018 at 10:51:49 UTC, CSim wrote:
Hi,
I'm trying to decide whether it is better to use DLang for Gtk
development or Vala/Genie.
When I make a simple Vala/Genie Gtk executable the file is tiny
whereas the DLang file is huge. First I used the default Dub
build and the file was in excess of 60mb (assuming this
includes debug build). Using dub build=release the file is
still more than 7 mb. Using a native Vala/Genie build the file
is less than 500k.
Trying to understand what is going on, but I assume from this
that Dub is linking static dependencies, whereas the Vala/Genie
builds will link to dynamic libraries.
So my (two pronged) question is this: Is there any way to
specify in dub.json to build and link dependencies as dynamic
libraries, and are there any other tips that can be used to
reduce these (relatively) huge executables?
Personally, I do not worry too much about the executable size,
however a couple of tips as follows:
a. If this is on linux use "strip" to remove symbols out of the
executable
b. In dub.json you can specify just the portions of GtkD that
your application depends on, i.e.:
"dependencies": {
"gtk-d:gtkd": {
"version": "3.7.5"
},
"gtk-d:vte": {
"version": "3.7.5"
}
}
Is what I use in tilix (https://github.com/gnunn1/tilix)
c. You can dynamically link to GtkD, in tilix I have the config
below to do so. Interestingly on ldc it doesn't make any
difference in size though using ldd I can see the dependency to
GtkD. With DMD it is smaller however I cannpt run it since the
Arch Linux GtkD package is compiled with ldc2.
{
"name": "dynamic",
"targetType": "executable",
"libs": ["gtkd-3"],
"libs-linux": ["X11"],
"lflags": ["-defaultlib=libgtkd-3.so"],
"versions": ["StdLoggerDisableTrace"]

Seems like Microsoft is pushing quite heavily for that in GUI code. Thanks for the link, I'm not active with .Net so I had to go look it up. Reminds me a lot of the way node.js works. If all your async activity is IO bound maybe it works fine and I'm wrong about this. My past experience has been that it's challenging to determine the appropriate times to yield particularly with a lot of async activity happening.

The second question is, if it would make sense at all to have such a thing? As previously noted, like other UI toolkits GTK maintains a single thread for processing UI events with an event loop running in that thread. GTK does support passing a function to be called when the main loop is idle, it could be possible to leverage this to manage fibers with appropriate yielding. Having said that, I'm in the camp where this doesn't make much sense. Using fibers on the main UI thread is likely going to result in a blocked UI whenever a fiber takes too long to do its work. History has shown that cooperative multi-tasking typically doesn't work well for UI applications. I think you would be much better off starting an additional thread and managing fibers in that thread outside the context of the main UI thread. You can then use things like std.concurrency to receive messages from the external thread to update the UI as needed in it's own thread.

Pass RegexMatch to a function?
I have a RegexMatch that I want to pass to a function that takes
the match and replaces various tokens in a string with the match

int i = 0;
foreach(group; match.captures) {
result = result.replace("$" ~ to!string(i), group);
i++;
}
return result;
}
When I try to compile this, it fails with the follow on the line
where replaceMatchTokens is declared:
Error: struct std.regex.RegexMatch(R, alias Engine =

Change Button Color back to standard Everything in GTK runs in the same thread, if your delay is a blocking one (i.e. putting the thread to sleep for 2 seconds) none of the GTK events will fire to redraw the button since the thread is occupied with your delay.

I still think it is a bad idea to claim the way with function calls as deprecated but introducing a new system which is not as flexible (but maybe more powerfull). C# with Visual Studio does it, PyQT does it: Function calls. It can be done fine with on the fly changes, i.e. random colors, it's somewhat more work then just calling a simple function call but CSS gives you a lot more power as well. I do this in Terminix where for certain themes I want to set the scrollbar background to be the same color as the terminal background. Essentially, add a class to the widget and then construct the CSS for the class with your random background color as a string. Create a CSSProvider and use loadFromData, same as captaindet's example, to load the CSS in the string. Finally, use the widget's style context to add the CSS provider which you just constructed. If you want to change the color, remove that provider and add a new one.

If you have a bunch of slots which take the same parameter types, not unusual in the GUI world, how would that work? The other thing that bugs me is lack of naming for slots and signals, again in the GUI world where you typically have dozens of these on an an individual widget differentiation is quite important. For my GtkD app where I need my own events between components outside of the built-in GTK ones I've just been rolling my own by hand using delegates similar to your example. It's pretty trivial but admittingly there is a bunch of boilerplate I'd love to eliminate via templates if there is a way to address the weaknesses with std.signals.

The signals would be String1 and String2, the slots watch1 and watch2. What I meant is that the connect call didn't seem to tie you to a specific slot, it looked like it determined the slot based on the types which is potentially error prone. Kagamin showed an example of explicitly connecting to a named slot so I'm happy with that, I'm looking forward to re-writing my event handlers using this technique. Always nice to learn something new.
Re: How do you draw in gtkD? Simple example overriding Widget.draw() doesn't compile.
Generally don't override methods in GtkD, use event handlers like addOnDraw. Because GtkD wraps GTK functions an overriden D method of GtkD will never get called by GTK since it is working with the underlying C functions directly.

I think i will need some time to understand this but one last question: Do the errors come from the fact at i didn't use those GTK thread mechanisms or that my function is not "spawnable"? "std.concurrency.spawn(F, T...)(F fn, T args) if(isSpawnable!(F,T))" "Error: template std.concurrency.spawn cannot deduce function from argument types!()(void delegate(Context cr, Widget widget), Scoped Widget), candidates are:" Keep in mind I know nothing about Cairo and I don't have time to try your code, but what happens if you remove the Scoped template from the Context parameter? Also, have you checked if Cairo is thread-safe the way you are using it in the spawned function? I'm not sure if Cairo has the same restrictions that GTK widgets do.

However this example it is based on using the GTk threadIdle callback which is generally preferred over the locking methods you show above, obviously though your use case may vary but keep in mind the locking methods have been deprecated, see the GTK 3 reference manual here: https://developer.gnome.org/gdk3/stable/gdk3-Threads.html You also see this GtkD issue here for https://github.com/gtkd-developers/GtkD/issues/137 for some code on how to use Delgates with gdk_threads_add_idle (i.e. GtkD gdk.Threads.threadsAddIdle).

In any GUI application there is a lot of idle time waiting for events, what the addThreadIdle allows you to do is take advantage of this and tell GTK that whenever it's sitting around doing nothing, give this function a call. The idea is that you spawn a thread that does your work and when GTK invokes your thread idle callback where you can check the status of the thread and update the UI accordingly. For example, let's say you need to render a highly complicated graph that takes a few minutes to complete. You could spawn a thread that renders it into an off-line buffer of some sort and once completed sends a message to the GTK main thread using std.concurrency. At some point GTK calls your thread idle callback and you simply invoke the std.concurrency.receive and see a message saying the graph has been rendered is available, and if so, copy it into the appropriate GTK widget. The important thing to understand is that the thread idle callback happens in the GTK main thread so it is completely safe to update GTK widgets from here. The other thing to understand is that whatever you work you do in the callback must be short, if you don't return in a reasonable amount of time you are blocking the main GTK thread. As a result it really should only be used as a mechanism to track work progress in whatever threads you have spawned. The GTK thread idle callback works beautifully with D's std.concurrency send and receive mechanism. Note the code I pointed you to in that D github Issue abstracts the extern (C) function from you and allows you to use normal D delegates as callbacks. The issue was created to get this incorporated into GtkD as I agree the framework should abstract this. Why is it not possible to write the value to the TreeView in D? I don't understand what you mean as of course it's possible to update value's in a TreeView. Do you mean why am I updating it from the callback (i.e. the C function)? The code here is an artificial example where it is simply updating the treeview with an iterating number generated in a separate thread. The results being posted to the TreeView could just as easily be a resultset from a long running database query, a complicated mathematical expression, etc. Hopefully the previous explanation helps you understand what the callback is doing. You can see a more real world example of GtkD multi-threading in this application I wrote called Visual Grep (https://github.com/gnunn1/vgrep), it puts a GTK GUI around grep with all searches running in background threads and updating Gtk TreeView as results come in. It also uses the delegate code linked in that issue which originally came from an application called grestful. Note Visual Grep was my first ever D/GtkD program so there is some ugh code in there, but hopefully it can act as an additional source of info for you.

Re: Regex start/end position of match?
Thanks Adam, that was the hint I needed. For a given RegexMatch the pre().length() is essentially equivalent to the start position and taking pre().length + hit.length() gives the end position so I think this should be OK for my needs.
Regex start/end position of match?
I'm using the std.regex API as part of Linux GUI grep utility I'm trying to create. I've got the GUI going fine using gtkd, the code to iterate over files (wow that was succinct in D, very impressive!), and getting matches via regex using the matchAll function. I'm stuck though on how to get the start/end index of a match? Looking at RegexMatch, I don't see an obvious way to get this? I'll admit that coming from Java I'm not very comfortable with the Range concept in D, however I read the Range and Regex D documentation as well as Andrei's article on ranges referenced in the docs and I'm still not seeing what I'm missing. By comparison, the Java API includes the start/end match index in the MatchResult interface. I have a feeling I'm not grokking something fundamental about Ranges in D, what am I missing? BTW in case anyone asks, the reason I'm looking for this is to highlight the matches when displaying matching lines in the GUI.
