correct, done.

Trying to build locally (with sandboxing, on NixOS) fails with the following error:

I see ofborg has the exact same problem trying to build gspeech. Unfortunately, I'm not too familiar with building python packages in nix, so my helping is limited.

This error: error: [Errno 13] Permission denied: '/homeless-shelter' usually happens when a program tries to write to the $HOME directory during the build ($HOME is set to /homeless-shelter which does not exist, on purpose), which is forbidden.

Found : I edited my project, pass to version 0.9.1 and updated my sha256 hash.

Confirmed, I can now build the project on NixOS with sandboxing enabled. Still I cannot run it, Binary runs, but fails. Is there some runtime dependencies I should have to test this?

The other binary seems to run fine though:

$ ./result/bin/gspeech-cli
gSpeech version 0.9.0
Usage : gSpeech-cli -i "[text to read]" ( or -f [txt file] ) -o [.wav filename] ... -l [optional lang]

Common flags:

-o   --output-file            name of the audio output file (wav type)

No problems with runtime dependencies. An other application bug (on first launch) ; correction on 0.9.2 version.
Seems fine now.

running gspeech-cli -i "hello world" gives me:

sh: pico2wave: command not found

This works fine: nix run nixpkgs.picotts -c ./result/bin/gspeech-cli -i "hello world". @mothsART you know better how this package should be used: do you think it should be a self contained unit, or just the frontend?

You can use wrapProgram to create a wrapper in charge of appending the runtime dependencies in the binary $PATH.

For instance:

This package is a fork of a fork of a fork. Is there a particular reason not to upstream your changes? Did you try to at least to open a PR upstream?

thanks to all: i use "wrapProgram" now and gspeech is working like a charm.

@NinjaTrappeur : this package is a fork of a fork, i'm aware of it.
Firstable, i've evolved gSpeech because I participate to a french Linux distribution (educative), who's naming Primtux : https://primtux.fr/

Last at least one year, the creator of Gspeech redirect to the fork : https://github.com/tuxmouraille/gSpeech/issues/4#issuecomment-454307959

I've pushed 2 PR to lusum repo, merged by him after a long time but reworked behind without PEP8, an ugly monolitic code...

My goal was to refactor for bring unit and fonctionnal test with CI, flake8 compatibility, add some algorithms and dictionnary to perform tts quality (french tts first), upgrade to python3 and gtk3, adapt for better debian and nix packaging etc.

Doing all of this in upstream would have taken me a lot longer and a lot of uncertainty.
If the project would have been more dynamic, I would probably have acted differently.

hmm, running gspeech does nothing for me. I need to kill it with ctrl+c. What is it supposed to do?

@Lassulus : gspeech launch an application indicator like this https://wiki.primtux.fr/lib/exe/detail.php/wiki:gspeech.png?id=gspeech

ah, I didn't have a tray, tested it now with stalonetray, everything works fine
