* $Log: ispell.h,v $
* Revision 1.41 1991/12/09 00:41:05 geoff
* Explicitly initialize tempfile to the null string, since we depend on
* this initialization. (Not strictly necessary, but I prefer to make it
* obvious that this initial value is required.)
*
* Revision 1.40 91/09/12 00:01:47 geoff
* Add definitions and header-file fields for the new TeX special
* characters.
*
* Revision 1.39 91/09/11 23:22:46 geoff
* Add TeX_comment.
*
* Revision 1.38 91/08/10 16:38:30 geoff
* Add vflag. Remove the typecasts in the ctype-style stuff, since they
* were unneeded and wrong.
*
* Revision 1.37 91/08/10 14:09:36 geoff
* Fix all of the ctype-style macros to properly typecast the character
* before testing it. Remove the lengthofchar macro. Change the
* *isstringch macros to allow stringchars to be only one character long.
*
* Revision 1.36 91/07/15 19:27:03 geoff
* Change all of the stringchar macros (*isstringch and lengthofchar) to
* accept a "canonical" parameter and pass it to stringcharlen.
*
* Revision 1.35 91/07/11 19:52:14 geoff
* Include stdio.h for the definition of BUFSIZ.
*
* Revision 1.34 91/07/05 19:51:45 geoff
* Add a proper declaration of done(), and remove the unused vb variable.
*
* Revision 1.33 91/07/03 18:20:50 geoff
* Add the chartoichar macro for conversion between chars and ichar_t's.
* Add the "ti" and "te" terminal capabilities.
*
* Revision 1.32 91/05/27 21:47:58 geoff
* Add data-structure support for the string-character type tables.
*
* Revision 1.31 90/12/31 00:59:47 geoff
* Reformat to follow a consistent convention throughout ispell
*
* Revision 1.30 90/10/14 01:51:39 geoff
* Add the "changes" and "readonly" variables.
*
* Revision 1.29 90/04/26 22:44:06 geoff
* Add fields and variables needed to support alternate string characters.
*
* Revision 1.28 89/12/27 22:29:08 geoff
* Add minword.
*
* Revision 1.27 89/07/11 00:24:11 geoff
* Add Amiga and REGEX_LOOKUP support from luis@rice.edu.
*
* Revision 1.26 89/07/07 23:26:29 geoff
* Add a complete set of external declarations, including using the
* new INIT macro to handle initialized declarations.
*
* Revision 1.25 89/06/09 15:54:45 geoff
* Add some lint ifdefs, so that the various macros can be checked by
* lint. Move the isXXXX macros to ispell.h from config.h, since they
* shouldn't be changed during configuration. Add support for the
* internal "character" type, ichar_t.
*
* Revision 1.24 89/04/28 01:11:16 geoff
* Change Header to Id; nobody cares about my pathnames.
*
* Revision 1.23 89/04/03 01:56:34 geoff
* Add support for string characters. Fix the magic number to be constant,
* and put the compilations in the hash header separately.
*
* Revision 1.22 89/02/22 23:16:18 geoff
* Add "contextsize" to the list of globals.
*
* Revision 1.21 89/02/20 22:10:36 geoff
* Define ALLFLAGS even if CAPITALIZATION is turned off.
*
* Revision 1.20 89/02/06 02:21:38 geoff
* Fix the offsets of TEX's left and right curlies and parens to match
* what the documentation specifies for the "texchars" statement.
*
* Revision 1.19 88/12/26 02:29:52 geoff
* Add a copyright notice.
*
* Revision 1.18 88/11/25 19:52:38 geoff
* Fix the SET/CLR/TSTMASKBIT macros to work correctly with masks of more
* than 32 bits.
*
* Revision 1.17 88/06/25 17:50:05 geoff
* Add hash header fields for the defaults set in the affix file: nroff
* and troff control characters, compound word (missing space) flag, and
* automatic affix-generation (try hard) flag. Update the magic number
* to reflect the change in hash formats.
*
* Revision 1.16 88/04/30 22:14:12 geoff
* Get rid of a bunch of unused termcap variables detected by lint.
*
* Revision 1.15 88/02/20 23:12:48 geoff
* Expand the handling of MASKBITS to provide more size options. Redo the
* capitalization handling structures. Change the magic number and its
* creation so that binary-incompatible configuration options will cause
* differing magic numbers. Add "struct success" to describe spelling
* hits. Add some new externals and delete some unused one.
*
* Revision 1.14 87/09/30 23:30:51 geoff
* Make the sort order a short so it can go past the range of a char. Add
* a bunch of globals that used to be scattered through .c files, plus
* one or two new ones to support the "nopossibilities" stuff.
*
* Revision 1.13 87/09/09 00:18:45 geoff
* Add sortval and sortorder to the hash header.
*
* Revision 1.12 87/09/03 23:17:30 geoff
* Get rid of a spurious WORDLEN definition, and use a different magic
* number for NO8BIT hash files.
*
* Revision 1.11 87/07/20 23:22:44 geoff
* Major changes to support table driving. Highlights include macros
* to support the new flag bits, removal of the X_flag fields from the
* table entry and replacement with the lumped masks, addition of language
* tables, and using a different magic number if CAPITALIZE is defined.
*
* Revision 1.10 87/06/27 12:20:32 geoff
* Add the "sg" termcap entry for braindamaged terminals.
*
* Revision 1.9 87/04/19 22:52:54 geoff
* Add fields for capitalization handling. Update MAGIC so it will refuse to
* work with uncapitalized hash files. Make hashheader a global.
*
* Revision 1.8 87/04/01 15:22:48 geoff
* Integrate Joe Orost's V7/register changes into the main branch
*
* Revision 1.7 87/03/22 23:56:32 geoff
* Fix minor bugs found by Dave Mason
*
* Revision 1.6 87/03/01 00:56:50 geoff

* some excess stuff caused by bad patching.
*
* Revision 1.5 87/02/28 14:58:21 geoff
* Add a full struct dent to the tree node structure.
*
* Revision 1.4 87/02/26 00:31:07 geoff
* Integrate McQueer's enhancements into the main branch
*
* Revision 1.3 87/01/19 00:06:41 geoff

#ifdef CAPITALIZATION
**
** If a word has only one capitalization form, and that form is not
** FOLLOWCASE, it will have exactly one entry in the dictionary. The
** legal capitalizations will be indicated by the 2-bit capitalization
** field, as follows:
**
** ALLCAPS The word must appear in all capitals.
** CAPITALIZED The word must be capitalized (e.g., London).
** It will also be accepted in all capitals.
** ANYCASE The word may appear in lowercase, capitalized,
** or all-capitals.
**
** Regardless of the capitalization flags, the "word" field of the entry
** will point to an all-uppercase copy of the word. This is to simplify
** the large portion of the code that doesn't care about capitalization.
** Ispell will generate the correct version when needed.
**
** If a word has more than one capitalization, there will be multiple
** entries for it, linked together by the "next" field. The initial
** entry for such words will be a dummy entry, primarily for use by code
** that ignores capitalization. The "word" field of this entry will
** again point to an all-uppercase copy of the word. The "mask" field
** will contain the logical OR of the mask fields of all variants.
** A header entry is indicated by a capitalization type of ALLCAPS,
** with the MOREVARIANTS bit set.
**
** The following entries will define the individual variants. Each
** entry except the last has the MOREVARIANTS flag set, and each
** contains one of the following capitalization options:
**
** ALLCAPS The word must appear in all capitals.
** CAPITALIZED The word must be capitalized (e.g., London).
** It will also be accepted in all capitals.
** FOLLOWCASE The word must be capitalized exactly like the
** sample in the entry. Prefix (suffix) characters
** must be rendered in the case of the first (last)
** "alphabetic" character. It will also be accepted
** in all capitals. ("Alphabetic" means "mentioned
** in a 'casechars' statement".)
** ANYCASE The word may appear in lowercase, capitalized,
** or all-capitals.
**
** The "mask" field for the entry contains only the affix flag bits that
** are legal for that capitalization. The "word" field will be null
** except for FOLLOWCASE entries, where it will point to the
** correctly-capitalized spelling of the root word.
**
** It is worth discussing why the ALLCAPS option is used in
** the header entry. The header entry accepts an all-capitals
** version of the root plus every affix (this is always legal, since
** words get capitalized in headers and so forth). Further, all of
** the following variant entries will reject any all-capitals form
** that is illegal due to an affix.
**
** Finally, note that variations in the KEEP flag can cause a multiple-variant
** entry as well. For example, if the personal dictionary contains "ALPHA",
** (KEEP flag set) and the user adds "alpha" with the KEEP flag clear, a
** multiple-variant entry will be created so that "alpha" will be accepted
** but only "ALPHA" will actually be kept.
