spellck.r

REBOL [ Title: "Spellck2" Purpose: "A spellchecked area" Usage: { Do this script before you create an area. like this: do/args %spellck.r 'load-only ;(without arg it runs demo) Then you have spellcked areas in your script. They flash nicely red if you press space, "." or such after a misspelled word. } License: { The dictionary is free, my code bsd. It contains a modified 'ctx-text which is owned by RT, but since you get that whith rebol it should be ok :) } Author: "Volker Nitsch" Date: 23-Aug-2003 Version: 1.0.0 Type: 'link-app File: %spellck.r Notes: { - The first time it downloads a big dictionary from rebol.org, and the rebol.org-interface-code. if you dont like that, change/remove that code and distribute the dictionary yourself. - The downloaded dictionary comes with ispell on suse8.0. I converted it to a simple one word/line format, because that performs best with rebol for quick loading and single lookups. Unfortunally the converters are years old and confuse myself, so i cannot convert newer dictionarys currently.. I was not sure about the copyright, some stuff there stated GPL, but a friend send me this: >> I was wondering if you would mind reposting your spell check scripts on developer , also I checked with Geoff Kuenning for a copyright clarification on the dictionaries and got the following reply .... "For all practical purposes, the ispell dictionaries are in the public domain. It's just not worth trying to do anything else. In the next release, I'll try to remember to explicitly place them in the PD. But in the meantime, feel free to use them in any manner you choose." << } Library: [ level: 'intermediate platform: 'all type: [package] domain: [gui ui user-interface vid] tested-under: none support: none license: 'BSD see-also: none ] ] ;;;;;;;;;;; spellchecking ctx-spellck2: context [ ;you may change this to another location: file: %words.txt ;attempt [delete file] ;force download while debugging if not exists? file [ use [win dl] [ win: view/new layout [ ta: area "Downloading rebol.org interface^/" wrap ] do http://www.rebol.org/library/public/lds-local.r append ta/text "Downloading dictionary. 500kb, with modem that taakes time..^/" show ta dl: lds/send-server 'get-package-file ["spellck.r/words.txt"] dl: decompress dl/data/file write file dl unview ] ] correct-words: read file wrong-word: func ["callback for eventually bad-word-collector" string] [] correct?: func [word /local res] [ res: any [ find correct-words join "^/" [word newline] 1 = length? word ] if not res [wrong-word word] found? res ] ;;;;; field-hooks letter: charset [#"A" - #"Z" #"a" - #"z" #"'"] other: negate letter spellcheck-trigger?: func [char] [ not find letter char ] spellcheck-last-word: func [string /local word left reversed] [ left: skip string -25 ;large enough? reversed: head reverse copy/part left string either parse/all reversed [copy word some letter to end] [ word: head reverse word correct? word ] [ true ;no text also ok.. ] ] ;;;;; based on ctx-text, changes marked with ;=== ctx-spellchecked-text: make object!
