I have a question I was just writing up, but when I realized Unix & Linux SE does not have a search-engine tag I thought that maybe this question would be considered off-topic for this site. Here is the question:

I would like to know if there is anyway I can search for Zsh themes that fulfil several specific criteria I specify to the search. Presently all search engines for Zsh themes I have found (including zshthem.es) do not appear to allow me to search for multiple specific features the theme possesses.

An Example to Clarify what I mean

For example, at the moment I am interested in using a Zsh theme with all of the following features:

• They display the local time in AM/PM format
• If the current working directory is a git repository it indicates whether or not all local changes have been pushed upstream.
• It uses different symbols for root and user prompts, respectively.
• It displays the hostname, username (e.g., root in a root prompt and the username in a non-root prompt) and a shortened form of the present working directory.

An example of what I am referring to with each of these criteria, is that previously I was using the gentoo Zsh theme, which for me (username: fusion809) when my current working directory is a git repository at ~/GitHub/PKGBUILDs/enlightenment which has unstaged commits displays: fusion809@brenton-pc ~/GitHub/PKGBUILDs/enlightenment (master*) $ as my user prompt. Where brenton-pc is my username, ~/GitHub/PKGBUILDs/enlightenment is the "shortened form of the present working directory" I was referring to, with the long form being, of course, /home/fusion809/GitHub/PKGBUILDs/enlightenment. The master* is how this theme indicates that I have unstaged commits to the git repository I am presently in. The dollar sign ($) denotes that the prompt is a user prompt, not a root prompt. So, the only thing the Gentoo theme lacks that I would like at the moment is that it does not display the local time in AM/PM format.

Summary

I want to be clear that my question is not me asking what theme fulfils the criteria I outlined in the previous "An Example to Clarify what I mean" section, but rather how I can search for such themes myself using a search engine or (if it is possible, which I suspect not) from the command-line.

so essentially I want to know if this question is on-topic and whether other questions relating to searching for themes, plugins, etc. for Unix/Linux software would be considered on-topic for this site?
