Batata: Yet another gtk4 app

hugopl · October 8, 2024, 6:00pm

Hi everyone,

I wrote a terminal emulator (it uses libvte4 that does the real stuff) for me and it may be useful for someone else.

I needed to write an UI component for a project of mine to hold widgets in tiled stacks, and all this inside tabs, then I as a (now former) Tilix user realized that this UI approach would be very interesting for terminal emulators, so Batata was born.

It still having some glitches here and there and leaking a bit of memory until I fix some known issue in GTK4 bindings… but I use it every day and enjoy , if you spawn several terminals and want to easily switch between them you may like it too.

It’s Linux/Gtk and there’s a flatpak build script, however I didn’t submit it to flathub yet.

You can find it at GitHub - hugopl/batata: An opinionated terminal emulator or see a small/ugly/improvised demo here https://www.youtube.com/watch?v=SdpsOAt3JpI

you need to run sudo make post-install, so it does things that usually the distro packages do, like update gnome icon cache and compile the gschema. I’ll add this to the readme.

hugopl · October 9, 2024, 5:15pm

You need the development package of the vte library, on ArchLinux it’s named vte4.

hugopl · October 9, 2024, 5:17pm

README.md updated.

kees · October 9, 2024, 5:55pm

Thanks for your reply!
My vte version is too low.
Tried to build vte myself, but the meson version was also too low.
I give up, I hope you can provide executables.
Since I can’t upgrade my Linux Mint 21.3 to 22, I’m investigating rolling linux distro’s Arch and Rhino, I’'l have to reinstall anyway…

zw963 · October 10, 2024, 3:02am

you need to run sudo make post-install,

It works! it is really cool(no title bar)

hugopl · October 10, 2024, 1:01pm

Did you try build the flatpak package? It was meant to solve exaclty these kind of problems.

kees · October 10, 2024, 6:53pm

Downloaded the sources to compile the interpreter, building without gave an error, but flatpak-builder seems to be missing

~~You need to install the flatpak-bulder. There’s probably a package for your distro.~~
oops, no, you have the flatpak-builder.

kees · October 12, 2024, 8:35am

Indeed, I could install flatpack-builder from the distro’s repo.
The building took quite a while, managed to keep all my 4 processors at 100%, but finally gave an error:

Any idea?

hugopl · October 12, 2024, 10:37pm

Seems it failed to compile vte?

The error is from gi-crystal, it didn’t find the vte files with introspection data for binding generation.

I ran the make flatpak here yesterday and it worked, I really have no idea why it failed with you… I’ll submit the flatpak to flathub soon, hope guys there could point anything that I may be doing wrong in the flatpak file.

The flatpak file is here, there’s a script that just inject the Crystal dependencies.
