Hi @psifertex, anything I can do to help the review process? Thanks!

Hey @xorhex! Thanks for the contribution. I've gone ahead and added the plugin to our community extension repository.

Thanks! Just learned that the community plugins are installed differently than locally deployed ones. Is there a recommended way to get Binary Ninja to pick up the rust component in addition to the python code (it picks up the python code no problem).

Currently, I'm doing this to copy the rust component in to the user plugin dir:

lib = Path(os.path.join(user_plugin_path(), "BinYars-SideWidget", get_os_libbinyars()))
if lib.exists():
    if is_supported():
        try:
            shutil.move(
                lib.resolve(), os.path.join(user_plugin_path(), get_os_libbinyars())
            )
            logger.log_info(
                f"Copied the BinYars rust binary, {get_os_libbinyars()}, into the plugin dir."
            )
        except Exception as ex:
            logger.log_error(f"Issue installing rust plugin: {ex}")
    else:
        logger.log_error(
            "Binaries are only provided for MacOS (arm64), Linux (x86_64), and Windows (x86_64). Plugin won't work unless you provide the compiled rust binary."
        )
else:
    logger.log_debug(f"{lib.resolve()} does not exists - nothing to install.")

I can still do this (drop it into the user plugin dir) but need to replace the user_plugin_path() in

lib = Path(os.path.join(user_plugin_path(), "BinYars-SideWidget", get_os_libbinyars()))

with another API call that will get the "community plugin path" instead.

Will the API call bundled_plugin_path() work for that in this instance @fosdickio ?

[xorhex]

Actually, this seems to work:

dirname, _ = os.path.split(os.path.abspath(__file__))
lib = Path(os.path.join(dirname, get_os_libbinyars()))

I'll cut another release.

I do have another question, I understand there is no way to hot reload Rust or C++ plugins so the user will need to restart Binary Ninja to force the Rust component to load. Any recommended guidance on doing this or should I just bake that into this plugin's UI (notifying the user to restart BN)?
