Distribution Obligations. + + 3.1. Application of License. + The Modifications which You create or to which You contribute are + governed by the terms of this License, including without limitation + Section 2.2. The Source Code version of Covered Code may be + distributed only under the terms of this License or a future version + of this License released under Section 6.1, and You must include a + copy of this License with every copy of the Source Code You + distribute. You may not offer or impose any terms on any Source Code + version that alters or restricts the applicable version of this + License or the recipients' rights hereunder. However, You may include + an additional document offering the additional rights described in + Section 3.5. + + 3.2. Availability of Source Code. + Any Modification which You create or to which You contribute must be + made available in Source Code form under the terms of this License + either on the same media as an Executable version or via an accepted + Electronic Distribution Mechanism to anyone to whom you made an + Executable version available; and if made available via Electronic + Distribution Mechanism, must remain available for at least twelve (12) + months after the date it initially became available, or at least six + (6) months after a subsequent version of that particular Modification + has been made available to such recipients. You are responsible for + ensuring that the Source Code version remains available even if the + Electronic Distribution Mechanism is maintained by a third party. + + 3.3. Description of Modifications. + You must cause all Covered Code to which You contribute to contain a + file documenting the changes You made to create that Covered Code and + the date of any change. You must include a prominent statement that + the Modification is derived, directly or indirectly, from Original + Code provided by the Initial Developer and including the name of the + Initial Developer in (a) the Source Code, and (b) in any notice in an + Executable version or related documentation in which You describe the + origin or ownership of the Covered Code. + + 3.4. Intellectual Property Matters + (a) Third Party Claims. + If Contributor has knowledge that a license under a third party's + intellectual property rights is required to exercise the rights + granted by such Contributor under Sections 2.1 or 2.2, + Contributor must include a text file with the Source Code + distribution titled "LEGAL" which describes the claim and the + party making the claim in sufficient detail that a recipient will + know whom to contact. If Contributor obtains such knowledge after + the Modification is made available as described in Section 3.2, + Contributor shall promptly modify the LEGAL file in all copies + Contributor makes available thereafter and shall take other steps + (such as notifying appropriate mailing lists or newsgroups) + reasonably calculated to inform those who received the Covered + Code that new knowledge has been obtained. + + (b) Contributor APIs. + If Contributor's Modifications include an application programming + interface and Contributor has knowledge of patent licenses which + are reasonably necessary to implement that API, Contributor must + also include this information in the LEGAL file. + + (c) Representations. + Contributor represents that, except as disclosed pursuant to + Section 3.4(a) above, Contributor believes that Contributor's + Modifications are Contributor's original creation(s) and/or + Contributor has sufficient rights to grant the rights conveyed by + this License. + + 3.5. Required Notices. + You must duplicate the notice in Exhibit A in each file of the Source + Code. If it is not possible to put such notice in a particular Source + Code file due to its structure, then You must include such notice in a + location (such as a relevant directory) where a user would be likely + to look for such a notice. If You created one or more Modification(s) + You may add your name as a Contributor to the notice described in + Exhibit A. You must also duplicate this License in any documentation + for the Source Code where You describe recipients' rights or ownership + rights relating to Covered Code. You may choose to offer, and to + charge a fee for, warranty, support, indemnity or liability + obligations to one or more recipients of Covered Code. However, You + may do so only on Your own behalf, and not on behalf of the Initial + Developer or any Contributor. You must make it absolutely clear than + any such warranty, support, indemnity or liability obligation is + offered by You alone, and You hereby agree to indemnify the Initial + Developer and every Contributor for any liability incurred by the + Initial Developer or such Contributor as a result of warranty, + support, indemnity or liability terms You offer. + + 3.6. Distribution of Executable Versions. + You may distribute Covered Code in Executable form only if the + requirements of Section 3.1-3.5 have been met for that Covered Code, + and if You include a notice stating that the Source Code version of + the Covered Code is available under the terms of this License, + including a description of how and where You have fulfilled the + obligations of Section 3.2. The notice must be conspicuously included + in any notice in an Executable version, related documentation or + collateral in which You describe recipients' rights relating to the + Covered Code. You may distribute the Executable version of Covered + Code or ownership rights under a license of Your choice, which may + contain terms different from this License, provided that You are in + compliance with the terms of this License and that the license for the + Executable version does not attempt to limit or alter the recipient's + rights in the Source Code version from the rights set forth in this + License. If You distribute the Executable version under a different + license You must make it absolutely clear that any terms which differ + from this License are offered by You alone, not by the Initial + Developer or any Contributor. You hereby agree to indemnify the + Initial Developer and every Contributor for any liability incurred by + the Initial Developer or such Contributor as a result of any such + terms You offer. + + 3.7. Larger Works. + You may create a Larger Work by combining Covered Code with other code + not governed by the terms of this License and distribute the Larger + Work as a single product. In such a case, You must make sure the + requirements of this License are fulfilled for the Covered Code. + +4. Inability to Comply Due to Statute or Regulation. + + If it is impossible for You to comply with any of the terms of this + License with respect to some or all of the Covered Code due to + statute, judicial order, or regulation then You must: (a) comply with + the terms of this License to the maximum extent possible; and (b) + describe the limitations and the code they affect. Such description + must be included in the LEGAL file described in Section 3.4 and must + be included with all distributions of the Source Code. Except to the + extent prohibited by statute or regulation, such description must be + sufficiently detailed for a recipient of ordinary skill to be able to + understand it. + +5. Application of this License. + + This License applies to code to which the Initial Developer has + attached the notice in Exhibit A and to related Covered Code. + +6. Versions of the License. + + 6.1. New Versions. + Netscape Communications Corporation ("Netscape") may publish revised + and/or new versions of the License from time to time. Each version + will be given a distinguishing version number. + + 6.2. Effect of New Versions. + Once Covered Code has been published under a particular version of the + License, You may always continue to use it under the terms of that + version. You may also choose to use such Covered Code under the terms + of any subsequent version of the License published by Netscape. No one + other than Netscape has the right to modify the terms applicable to + Covered Code created under this License. + + 6.3. Derivative Works. + If You create or use a modified version of this License (which you may + only do in order to apply it to code which is not already Covered Code + governed by this License), You must (a) rename Your license so that + the phrases "Mozilla", "MOZILLAPL", "MOZPL", "Netscape", + "MPL", "NPL" or any confusingly similar phrase do not appear in your + license (except to note that your license differs from this License) + and (b) otherwise make it clear that Your version of the license + contains terms which differ from the Mozilla Public License and + Netscape Public License.

It is also a command-line tool for +Linux, Unix-like and other OSes. + +It is designed for quick and high quality spell checking and +correcting for languages with word-level writing system, +including languages with rich morphology, complex word compounding +and character encoding. + +Hunspell interfaces: Ispell-like terminal interface using Curses +library, Ispell pipe interface, C++/C APIs and shared library, also +with existing language bindings for other programming languages. + +Hunspell's code base comes from OpenOffice.org's MySpell library, +developed by Kevin Hendricks (originally a C++ reimplementation of +spell checking and affixation of Geoff Kuenning's International +Ispell from scratch, later extended with eg. n-gram suggestions), +see http://lingucomponent.openoffice.org/MySpell-3.zip, and +its README, CONTRIBUTORS and license.readme (here: license.myspell) files. + +Main features of Hunspell library, developed by László Németh: + + - Unicode support + - Highly customizable suggestions: word-part replacement tables and + stem-level phonetic and other alternative transcriptions to recognize + and fix all typical misspellings, don't suggest offensive words etc. + - Complex morphology: dictionary and affix homonyms; twofold affix + stripping to handle inflectional and derivational morpheme groups for + agglutinative languages, like Azeri, Basque, Estonian, Finnish, Hungarian, + Turkish; 64 thousand affix classes with arbitrary number of affixes; + conditional affixes, circumfixes, fogemorphemes, zero morphemes, + virtual dictionary stems, forbidden words to avoid overgeneration etc. + - Handling complex compounds (for example, for Finno-Ugric, German and + Indo-Aryan languages): recognizing compounds made of arbitrary + number of words, handle affixation within compounds etc. + - Custom dictionaries with affixation + - Stemming + - Morphological analysis (in custom item and arrangement style) + - Morphological generation + - SPELLML XML API over plain spell() API function for easier integration + of stemming, morpological generation and custom dictionaries with affixation + - Language specific algorithms, like special casing of Azeri or Turkish + dotted i and German sharp s, and special compound rules of Hungarian. + +Main features of Hunspell command line tool, developed by László Németh: + + - Reimplementation of quick interactive interface of Geoff Kuenning's Ispell + - Parsing formats: text, OpenDocument, TeX/LaTeX, HTML/SGML/XML, nroff/troff + - Custom dictionaries with optional affixation, specified by a model word + - Multiple dictionary usage (for example hunspell -d en_US,de_DE,de_medical) + - Various filtering options (bad or good words/lines) + - Morphological analysis (option -m) + - Stemming (option -s) + +See man hunspell, man 3 hunspell, man 5 hunspell for complete manual. + +Translations: Hunspell has been translated into several languages already.

This file +is whitespace delimited. + +SFX D Y 4 +SFX D 0 e d +SFX D y ied [^aeiou]y +SFX D 0 ed [^ey] +SFX D 0 ed [aeiou]y + +This information can be interpreted as follows: + +In the first line has 4 fields + +Field +----- +1 SFX - indicates this is a suffix +2 D - is the name of the character flag which represents this suffix +3 Y - indicates it can be combined with prefixes (cross product) +4 4 - indicates that sequence of 4 affentry structures are needed to + properly store the affix information + +The remaining lines describe the unique information for the 4 SfxEntry +objects that make up this affix. Each line can be interpreted +as follows: (note fields 1 and 2 are as a check against line 1 info) + +Field +----- +1 SFX - indicates this is a suffix +2 D - is the name of the character flag for this affix +3 y - the string of chars to strip off before adding affix + (a 0 here indicates the NULL string) +4 ied - the string of affix characters to add +5 [^aeiou]y - the conditions which must be met before the affix + can be applied + +Field 5 is interesting. Since this is a suffix, field 5 tells us that +there are 2 conditions that must be met. The first condition is that +the next to the last character in the word must *NOT* be any of the +following "a", "e", "i", "o" or "u". The second condition is that +the last character of the word must end in "y". + +So how can we encode this information concisely and be able to +test for both conditions in a fast manner? The answer is found +but studying the wonderful ispell code of Geoff Kuenning, et.al. +(now available under a normal BSD license). + +If we set up a conds array of 256 bytes indexed (0 to 255) and access it +using a character (cast to an unsigned char) of a string, we have 8 bits +of information we can store about that character. Specifically we +could use each bit to say if that character is allowed in any of the +last (or first for prefixes) 8 characters of the word. + +Basically, each character at one end of the word (up to the number +of conditions) is used to index into the conds array and the resulting +value found there says whether the that character is valid for a +specific character position in the word. + +For prefixes, it does this by setting bit 0 if that char is valid +in the first position, bit 1 if valid in the second position, and so on. + +If a bit is not set, then that char is not valid for that postion in the +word. + +If working with suffixes bit 0 is used for the character closest +to the front, bit 1 for the next character towards the end, ..., +with bit numconds-1 representing the last char at the end of the string. + +Note: since entries in the conds[] are 8 bits, only 8 conditions +(read that only 8 character positions) can be examined at one +end of a word (the beginning for prefixes and the end for suffixes. + +So to make this clearer, lets encode the conds array values for the +first two affentries for the suffix D described earlier. + + + For the first affentry: + numconds = 1 (only examine the last character) + + conds['e'] = (1 << 0) (the word must end in an E) + all others are all 0 + + For the second affentry: + numconds = 2 (only examine the last two characters) + + conds[X] = conds[X] | (1 << 0) (aeiou are not allowed) + where X is all characters *but* a, e, i, o, or u + + + conds['y'] = (1 << 1) (the last char must be a y) + all other bits for all other entries in the conds array are zero + +#endif diff --git a/extensions/spellcheck/hunspell/src/affentry.hxx b/extensions/spellcheck/hunspell/src/affentry.hxx new file mode 100644 index 0000000000..b736bf0350 --- /dev/null +++ b/extensions/spellcheck/hunspell/src/affentry.hxx @@ -0,0 +1,223 @@ +/* ***** BEGIN LICENSE BLOCK ***** + * Version: MPL 1.1/GPL 2.0/LGPL 2.1 + * + * Copyright (C) 2002-2022 Németh László + * + * The contents of this file are subject to the Mozilla Public License Version + * 1.1 (the "License"); you may not use this file except in compliance with + * the License.
