Quicksearch

Quicksearch is a search-engine-interface for Common Lisp. The goal of Quicksearch is to find a CL library quickly. For example, if you want to find libraries about json, just type (qs:? "json") at the REPL.

The function quicksearch searches for CL projects on Quicklisp, Cliki, GitHub and BitBucket, then outputs results in the REPL. The function ? is an abbreviation wrapper for quicksearch.

quicksearch accepts arguments in a long form: :url, :description, etc, and ? has the same in their short form: :u, :d, and they are agglutinated: (qs:? :gq) to limit the search to :github and :quicklisp.

Quicksearch was created by @tkych: https://github.com/tkych/quicksearch.

T

• If search-results is not null, then results are printed and return T.
• Since bitbucket-result is null, it is not printed.

URL, description:

Quicksearch printed the projects' short description and their URL by default.

To not print them, set their variables to NIL: *url-print?* and *description-print?*.

CL-REPL> (qs:? "crypt") ;<=> (qs:quicksearch "crypt" :description t :url t)

• A symbol (as search-word) is automatically converted into a downcase-string.
• The function QUICKSEARCH's options are redundant, but explanatory.
• The function ?'s options are not explanatory, but minimum.

Null result:

CL-REPL> (qs:? "supercalifragilisticexpialidocious") ;<=> (qs:quicksearch "supercalifragilisticexpialidocious")
NIL

• If it raises a threading error, probably your CL system might be not support threads. In this case, please type (qs:config :threading? nil) at REPL, then try it again.
• If search-results is null, then just return NIL.

Search targets, max printed projects

You can use long and short parameters to specify where to search.

Quicksearch defaults to GitHub, Quicklisp, Cliki and bitbucket.

Only search on GitHub with a short :g option, and limit the number of printed results to 4:

CL-REPL> (qs:? "crypt" :g 4) ;<=> (qs:quicksearch "crypt"
                             ;                    :cut-off 4
                             ;                    :quicklisp nil :cliki nil :bitbucket nil)

Reference Manual

[function] QUICKSEARCH search-word &key :web :description :url :cut-off :quicklisp :cliki :github :bitbucket

QUICKSEARCH searches for CL projects with search-word in Quicklisp, Cliki, GitHub and BitBucket. search-word must be a string, number or symbol (symbol will be automatically converted into downcase-string).

Keywords:

• If :web is NIL, it does not search in Cliki, GitHub and BitBucket.
• If :quicklisp is NIL, it does not search in Quicklisp (also :cliki, :github, :bitbucket).
• At least one search-space must be specified.
• If :description is T, it displays project's descriptions (QuickDocs-url for Quicklisp-search).
• If :url is T, it display project's url.
• :cut-off is the max number of results to print for each source. It doesn't limit the number of HTTP requests. See the CONFIG for this.

Note: about spaces in the search term

• About #\Space in search-word:

  In case search-word contains #\Space, Quicklisp-search is OR-search, whereas Cliki-search, GitHub-, BitBucket- is AND-search.

  e.g. (quicksearch "foo bar") Quicklisp-search for "foo" OR "bar". Cliki-search, GitHub-, BitBucket- for "foo" AND "bar".

[function] ? search-word &rest options

? is abbreviation wrapper for function QUICKSEARCH. search-word must be a string, number or symbol. options must be a non-negative integer (as Cut-Off) and/or some keywords which consists of some Option-Chars.

Examples:

(? "crypt")
<=>
(quicksearch "crypt" :description T :url T :cut-off 50
                     :quicklisp t :cliki t :github t :bitbucket t)

(? "crypt" :du 10)
<=>
(quicksearch "crypt" :description T :url T :cut-off 10
                     :quicklisp t :cliki t :github t :bitbucket t)

(? "crypt" 20 :g)
<=>
(quicksearch "crypt" :description T :url T :cut-off 20
                     :quicklisp nil :cliki nil :github T :bitbucket nil)

Options:

• Cut-Off:

  • The max number of printing results (default is 50).

• one-letter options (case doesn't matter):

  • d -- output Description (or QuickDocs-url for Quicklisp-search) (t by default)
  • u -- output URL (t by default)
  • q -- search in Quicklisp
  • c -- search in Cliki
  • g -- search in GitHub
  • b -- search in Bitbucket

NOTE: we changed the default (2024-07) to print the short description and project URL, there is currently no keyword to not print them. Use the global variables or a CONFIG (?).

Note:

• Option-Char is idempotent (e.g. :dd <=> :d).
• The order of Option-Chars is nothing to do with output. (e.g. :du <=> :ud)
• If options contains more than 2 Cut-Offs, only last one is applied.
• The order of options is nothing to do with output (except for some Cut-Offs).
• If no search space is specified, all spaces is specified (e.g. :d <=> :dqcgb)
• If at most one search space is specified, then others are not specified.

[function] CONFIG &key maximum-columns-of-description maximum-number-of-fetching-repositories cache-size clear-cache? threading? quicklisp-verbose?

Function CONFIG customizes printing, fetching or caching.

Keywords:

• :maximum-columns-of-description The value must be a plus integer bigger than 5. If the length of description-string is bigger than this value, then output of description is inserted newline for easy to see. Default value is 80.

• :maximum-number-of-fetching-repositories This value controls the number of fetching repositories. The value must be a plus integer. Increasing this value, the number of fetching repositories increases, but also space & time does. Default value is 50.

• :cache-size The value must be a plus integer. This value is the number of stored previous search-results. Increasing this value, the number of caching results increases, but also space does. Default value is 4.

• :clear-cache? The value must be a boolean. If value is T, then clear all caches.

• :threading? The value must be a boolean (default T). If value is NIL, then QUICKSEARCH becomes not to use threads for searching.

  Note: Currently in SBCL (1.1.8), threads are part of the default build on x86[-64] Linux only. Other platforms (x86[-64] Darwin (Mac OS X), x86[-64] FreeBSD, x86 SunOS (Solaris), and PPC Linux) experimentally supports threads and must be explicitly enabled at build-time. For more details, please see SBCL manual.

• quicklisp-verbose? The value must be a boolean (default NIL). If value is T, then outputs version of quicklisp and whether library had installed your local.

  Example:

     CL-REPL> (qs:config :quicklisp-verbose? T)
     CL-REPL> (qs:? "json" :q)

     SEARCH-RESULTS: "json"

      Quicklisp: 2013-04-20   ;<- quicklisp version
       !cl-json               ;<- if library has installed via quicklisp, print prefix "!".
       !cl-json.test
       com.gigamonkeys.json   ;<- if not, none.
       json-template
       st-json
     T

Note:

If you would prefer permanent config, for example, add codes something like the following in the CL init file.

In .sbclrc for SBCL, ccl-init.lisp for CCL:

(ql:quickload :quicksearch)
(qs:config :maximum-columns-of-description 50
           :maximum-number-of-fetching-repositories 20
           :cache-size 2
           :threading? nil
           :quicklisp-verbose? t)

[special variable] *USER-AGENT*

*user-agent* tells the server who is requested (i.e. User-Agent header value). If you are embedding quicksearch in a larger application, you should change the value of *user-agent* to your application name and URL.
