Flyout language selector doesn't show current language after upgrading to RTD Theme 3.0.0

[Hyrla]

Problem

I am not sure if this issue is related to RTD Theme or new addon system. Right now, flyout language selector doesn't show current language. Before upgrading to 3.0.0 (I was using 2.0.0), all language choices were shown.

Reproducible Project

Error Logs/Results

Expected Results

Is there a way to display all available languages (including the one that is currently used) like before? On my screenshots, I only see French option when I am reading in English. In French version, I can only see English version.

Environment Info

• Python Version: 3.12
• Sphinx Version: 8.3.1
• RTD Theme Version: latest (3.0.1)

Thanks for reporting this. It seems a bug in this chunk of code:

sphinx_rtd_theme/sphinx_rtd_theme/static/js/versions.js_t

Lines 6 to 26 in 7b894f5

	function renderLanguages(config) {
	if (!config.projects.translations.length) {
	return "";
	}
	const languagesHTML = `
	<dl>
	<dt>{{ _('Languages') }}</dt>
	${config.projects.translations
	.map(
	(translation) => `
	<dd ${translation.slug == config.projects.current.slug ? 'class="rtd-current-item"' : ""}>
	<a href="${translation.urls.documentation}">${translation.language.code}</a>
	</dd>
	`,
	)
	.join("\n")}
	</dl>
	`;
	return languagesHTML;
	}

It should be injecting this.config.projects.current, similar to what CPython's code is doing: https://github.com/python/cpython/blob/67f6e08147bc005e460d82fcce85bf5d56009cf5/Doc/tools/static/rtd_switcher.js#L23-L25

I forgot to do that when I migrated that work here.

I just released v3.0.2 that includes this fix. Please let us know if it works as expected.
