The purpose of this package is to facilitate searching things on the web directly from Emacs (without needing to resort to eww). You can customize specific search engines for specific modes (and even set engines globally).

Simply copy quick-search.el's source code into your init.el. After that, you can add the configuration code.

There are 2 function that you need to set up in order to use quick-search

quick-search/set-preferred-browser configures your browser of choice. It has two arguments:

1. Your preferred browser's name
2. Any command line arguments you'd like to pass

Examples:

• (quick-search/set-preferred-browser "firefox" "")
• (quick-search/set-preferred-browser "chromium" "--incognito")

quick-search/add-search-engine adds a search engine to the search engine list. It has 3 arguments:

1. The name of the search engine
2. Search engine link (normally found on the URL of websites after searching for something)
3. A quoted list of modes you'd like the search engine to be enabled in. Write nil if you'd like to enable it globally. Examples:

• (quick-search/add-search-engine "Google" "https://google.com/search?q=" nil)
• (quick-search/add-search-engine "YouTube" "https://www.youtube.com/results?search_query=" '(elisp-mode js-mode rust-mode))
• (quick-search/add-search-engine "C plus plus" "https://cplusplus.com/search.do?q=" '(c++-mode c-mode))

Simply call the quick-search function after having it configured (you need to have a selected browser and at least 1 search engine)

; This sets firefox as the default browser with no extra arguments
(quick-search/set-preferred-browser "firefox" "")

; Adds google search engine to be enabled in all the modes
(quick-search/add-search-engine "Google" "https://google.com/search?q=" nil)

; Same thing as above but for Wikipedia
(quick-search/add-search-engine "Wikipedia" "https://en.wikipedia.org/w/index.php?search=" nil)

; Enables C Plus Plus website for both C and C++ mode
(quick-search/add-search-engine "C plus plus" "https://cplusplus.com/search.do?q=" '(c++-mode c-mode))

; Enables oxford dictionary for "Writing" modes
(quick-search/add-search-engine "Oxford Dictionary" "https://www.oxfordlearnersdictionaries.com/definition/english/" '(org-mode latex-mode LaTeX-mode tex-mode markdown-mode))

; Disable the async shell command window. Source: https://emacs.stackexchange.com/a/58341/39379
(add-to-list 'display-buffer-alist '("*Async Shell Command*" display-buffer-no-window (nil)))

You can even add the function to a keybinding.

(global-set-key "\C-c\C-s" 'quick-search)
