First trying with rust in weechat

[fesnavarro]

Hello Guys, please don't kill me.

I cloned the repo and cargo build it to create those compiled files.

Should I mkdir /usr/share/weechat/rust than moving those compiled from weechat/src/*rs to there?

I've used some scripts with python and lua plugin, but I never added such a thing as a new language plugin before the scripts.

Everything else I've I got from apt, for instance, apt install weechat-python. So how to do it in manual?

Sorry for asking it here.

You need to create a new crate, docs for this can be found in the official Rust docs: https://doc.rust-lang.org/cargo/guide/creating-a-new-project.html#creating-a-new-package. Make sure that the type will be --lib.

The examples in this repo are a good starting point, e.g. https://github.com/poljar/rust-weechat/blob/master/weechat/examples/sample/Cargo.toml. You'll need to replace the weechat dependency line to depend on a released version of this crate, that is replace the path with version = 0.4.0. As 0.4.0 is the latest release on crates.io.

Okay, let me see if I'm doing it right.

These are the steps. "git clone" not this repo but "weechat-matrix-rs" instead cd weechat-matrix-rs && cargo new newname --lib cd newname && vim Cargo.toml replace dependence path with weechat = "0.4.0" "cargo build" it then use the target folder and copy it into .weechat / plugins?

Are you trying to build weechat-matrix-rs or are you trying to create your own plugin?

I'm trying to build weechat-matrix-rs but I got stuck here.

In that case you need to point the env variable WEECHAT_PLUGIN_FILE to the weechat-plugin.h file you want to use and just call make install inside the weechat-matrix-rs repository.

$ WEECHAT_PLUGIN_FILE="/home/whatever/weechat-plugin.h" make install

I've tried with and without quotes. Same result: make compiled without errors Then WEECHAT_PLUGIN_FILE="/thepathIfound/weechat-plugin.h" make install WEECHAT_PLUGIN_FILE='/thepathIfound/weechat-plugin.h' make install WEECHAT_PLUGIN_FILE=/thepathIfound/weechat-plugin.h make install

Shouldn't "Rust" appear in the list of plugins?

The environment variable is a build time option, not a install time option.

$ WEECHAT_PLUGIN_FILE="/thepathIfound/weechat-plugin.h" cargo build && make install

We're using cargo directly since make will think there's nothing to do but cargo will correctly notice that the environment variable got changed.

No, the name of the plugin is matrix. The Rust bindings are creating plugins that work without going through a language specific plugin.
