Nice post, interesting read and good marketing for D, though 
would be nice if it had a link to dlang.org.  Someone should post 
this to reddit tomorrow.

So, how hard would it be for you to swap out parts of the 
backend? I wrote a terminal emulator in scratch in D for myself 
and have some nifty features hacked in already.

Since Terminix is a GTK 3 application, the minimum baseline is 
that your emulator would have to be a GTK 3 Widget, I have no 
idea what would be involved in creating a GTK widget in D as I've 
never tried it myself.

Terminix uses the GTK VTE widget for terminal emulation, so the 
more of that API that you implement the easier it is to 
incorporate it. Having said that, if you got it to the point 
where it worked as a base GTK widget I'd be happy to support it 
as an experimental item and abstract the interface along with 
turning off the functionality that it doesn't support compared to 
GTK VTE.

However note that to get things to the point where it could 
actually be shipped with Terminix for use by the end user is I 
suspect a substantial amount of work. I don't know how feature 
complete your emulator is, but looking at the VTE source code as 
well as the source code for other emulators it's a surprisingly 
complicated area with a lot of edge cases. Things like 
transparency, unicode, buffering output to temp files with 
encryption and various performance issues all come to mind. I 
think you mentioned previously that vi works fine in your 
emulator so you've already gotten over one of the major hurdles.

I do have a desire at some point to switch to a D written 
solution for the actual terminal emulation at some point. I 
haven't done it so far because I believe it is a huge amount of 
work and I have my plate full just dealing with the application 
side of things. However, If you are interested in working on that 
I would be very interested in supporting you in that endeavor. 
Feel free to ping me on IRC and we can discuss in more detail.

You could also rip out the logic and the system calls and so forth and 
hook them up (laboriously) to a TextView with appropriate styling. Which 
is probably nontrivial on both sides.

I glanced over a python-based terminal emulator the other day. It was 
intended as a simple and straightforward example, I think. It was over 
four thousand lines of code. I'm not about to try implementing my own.

I'm not sure a textview would be viable, it might work for the 
command prompt but I doubt it would handle ncurses type 
applications like vi or nano very well. I also suspect the 
performance wouldn't be very good when dealing with a lot of 
output like cat'ing a large file.

I don't know GTK at all, but my terminal thing's frontend just 
needs keyboard and mouse input events and a canvas to draw onto 
(including text string drawing functions).

So I'm guessing the TextView is actually overfeatured for what 
I'd want.

Yep, that would be my expectation. I suspect you would just 
inherit from GtkWidget and go from there.

Yeah, I don't use GTK at all, my backend is pure code (it is an 
abstract class where you implement a few methods to actually do 
user interaction, while the terminal emulation guts are in that 
class) and the frontend is X11/Win32.

It'd prolly be a bit of work then to wrap up my thing with the 
GTK UI implementation.

Yes, indeed, far more complicated than you'd think! But I have 
actually used mine as my real world terminal emulator for about 
two years now, including with several complex existing programs 
(vim, mutt, finch, and many others) and it works well.


 Feel free to ping me on IRC and we can discuss in more detail.


Yeah, we'll have to talk about it some day, the glue code would 
be a pain for both of us but once that's done I think our two 
sides could coexist well.

Hi Gerald,

There's this tutorial from Davyd Madeley about writing a 
clock-widget (this is Gtk2) in C:
