I'm am starting a new thread because I've completed my task.

Here is a terminal component for Lazarus that is easy to reuse.

https://cache.getlazarus.org/archives/terminal.7z

To install, make sure you're on Linux with a Gtk2 copy of Lazarus. Open package terminaldsgn.lpk, install, and rebuild the IDE. You'll have a TTerminal component on your pallet. Drop it on a form, press run, and you have your own terminal program.

Here is a longish video walk through of how it works:

https://cache.getlazarus.org/videos/vte-finished.mp4

The source code is completely free, copy left, if anyone wants to reuse it.

Notes, you need to be using Linux and have libvte for gtk2 installed to use the component. You can be running other platforms, but you'll just see the design time surface it you're not on Linux.

I updated my archive to include support for a dockable window inside the Lazarus IDE.

Very good initiative (Visual Studio Code inspired) . I wish to had this for Windows too :)

Huh ? Slight historical misinformation here.

Linux editors had this decennia before Visual Studio came up with it.

Michael.

By the way, there is a small bug with the IDE I discovered while making this. If you dock a window, then right click and close it, or undock it, window cannot be docked again. You have to restart the IDE to be able to dock that window type. Here is a screen capture of the issue:

Huh? What is wrong with you? Where you have historical misinformation? It is personal view. It looks similar like in VSC and probably like in many other editors in positive meaning.

Feel free to provide full historical context. Insane.

I cannot speak for others, but I read your statement as stating that the idea of an embedded terminal comes from VSC.
If this is not what you meant, I apologize for my reaction.

Michael.

I appreciate your work.

Did you ever try to make it cross platform? I only ask as I have not found a good way to embed either PowerShell or cmd.exe.

R0b0t1,

If you look at the sources you'll see I simply wrapped some of the functionality of gnome's terminal component inside a LCL TCustomControl class. Two function calls actually, vte_terminal_new and vte_terminal_fork_command_full. The gnome tool kit, or gtk for short, takes care of the rest. Its functionality includes text styles (bold, underline), colors, keyboard accelerators, hyperlinks, command history, variable expansion, among other things. But as this is implemented by the gnome tool kit for Linux, sorry it's not portable.

However, if you just want to embed a text terminal with no features other than typing text and executing command, and have those results shown in the same window, it can be easily done on any platform with a TMemo control and TProcess class using pipes to redirect stdin, stdout, and stderr. -------------- next part --------------

I did it years ago for cmd.exe on Delphi, I think it used pipes in some form.

There is a bit more to adapt all features of cmd.exe, especially colors. The interface is handled by a windows DLL and kind of clunky, so you need to hook functions. That is why I was wondering if it had already been done.

I've posted this project to github:

https://github.com/sysrpl/Lazarus.Terminal

Enhancements now include custom colors and fonts.

A comparison of terminal emulators. Most are using VTE. -------------- next part --------------

for

Lazarus 1.9.0 r57653 FPC 3.0.4 x86_64-linux-gtk2

you need also dynlibs in gtk2term:

uses
   GLib2, Gtk2, dynlibs;

That is how I read his message as well. And I fully agree Michael - I think Linux editors beat Visual Studio on that one by quite a few years. :-)

Graeme

Maybe someone can clarify the Dynlibs unit issue, because I'm on the same toolkit, platform, and compiler, yet there is no need to include Dynlibs. -------------- next part --------------
