web-search plugin

This plugin adds aliases for searching with Google, Wiki, Bing, YouTube and other popular services.

Open your ~/.zshrc file and enable the web-search plugin:

plugins=( ... web-search)

Usage

You can use the web-search plugin in these two forms:

• web_search <context> <term> [more terms if you want]
• <context> <term> [more terms if you want]

For example, these two are equivalent:

$ web_search google oh-my-zsh
$ google oh-my-zsh

Available search contexts are:

Context	URL
bing	https://www.bing.com/search?q=
google	https://www.google.com/search?q=
yahoo	https://search.yahoo.com/search?p=
ddg or duckduckgo	https://www.duckduckgo.com/?q=
sp or startpage	https://www.startpage.com/do/search?q=
yandex	https://yandex.ru/yandsearch?text=
github	https://github.com/search?q=
baidu	https://www.baidu.com/s?wd=
ecosia	https://www.ecosia.org/search?q=
goodreads	https://www.goodreads.com/search?q=
qwant	https://www.qwant.com/?q=
givero	https://www.givero.com/search?q=
stackoverflow	https://stackoverflow.com/search?q=
wolframalpha	https://wolframalpha.com/input?i=
archive	https://web.archive.org/web/*/
scholar	https://scholar.google.com/scholar?q=

Also there are aliases for bang-searching DuckDuckGo:

Context	Bang
wiki	!w
news	!n
youtube	!yt
map	!m
image	!i
ducky	!

Custom search engines

If you want to add other search contexts to the plugin, you can use the $ZSH_WEB_SEARCH_ENGINES variable. Set it before Oh My Zsh is sourced, with the following format:

ZSH_WEB_SEARCH_ENGINES=(
    <context> <URL>
    <context> <URL>
)

where <context> is the name of the search context, and <URL> a URL of the same type as the search contexts above. For example, to add reddit, you'd do:

ZSH_WEB_SEARCH_ENGINES=(reddit "https://www.reddit.com/search/?q=")

These custom search engines will also be turned to aliases, so you can both do web_search reddit <query> or reddit <query>.
