Quicksearch

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

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

Installation

cl-test-grid results:

Auto:
  1. CL-REPL> (ql:quickload :quicksearch)
Manual:
  1. SHELL$ git clone https://github.com/tkych/quicksearch.git
  2. CL-REPL> (push #p"/path-to-quicksearch/quicksearch/" asdf:*central-registry*)
  3. CL-REPL> (ql:quickload :quicksearch) or (asdf:load-system :quicksearch)

Examples

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.
Simple search:
CL-REPL> (qs:? "crypt") ;<=> (qs:quicksearch "crypt")

  • If cut-off is supplied (above 4), then the number of output results is bellow cut-off (the number (above 2) after .......> is number of remains).
  • The order of options is nothing to do with search-result (e.g. :ug 4 <=> 4 :gu <=> :u 4 :g <=> ...).

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 printing repositories each space.
Note:
  • ?cut-off controls only printing results, nothing to do with the max number of fetching repositories. see. function CONFIG documentation

  • 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 nil :?url nil :?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 :d)
<=>
(quicksearch "crypt" :?description T :?url nil :?cut-off 20
                     :?quicklisp nil :?cliki nil :?github T :?bitbucket nil)
Options:
  • Cut-Off:

    • The max number of printing results (default is 50).
  • Option-Chars:

    • d, D -- output Description (or QuickDocs-url for Quicklisp-search)
    • u, U -- output URL
    • q, Q -- search in Quicklisp
    • c, C -- search in Cliki
    • g, G -- search in GitHub
    • b, B -- search in Bitbucket
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.

TODO

  • ADD search-space: Common-Lisp.net
  • ADD search-space: Google code
