An exception may have a minimum length of 3 and a maximum length of 49 characters.
Only letters (no special characters !) are permissible in the first two positions
of an exception, except - and ' which are accepted in 2.-position
(e.g., A-bend or c'est ).
The abbreviation asterix * may only be placed at the end of a word.
Exceptions ending on an asterix * mean that up to the * every hyphenation is
provided as specified. All the succeeding characters of the word are processed by
hyphenation logic starting at the last hyphen found in the exception.Example: lau-f* ==> lauf lau-fe lau-fen lau-fend lau-fen-den but: ==> lau-fsper-re (and other errors !!)
To avoid errors like those created by exception writing, in exceptions with less
than two letters between the last hyphen and the concluding *, the program logic
of some languages will check whether these syllable-start-letters are allowed.
If not, the last hyphen is corrected automatically:lau-fsperre ==> lauf-sperre (has been corrected) Example: Kam-bo-d* ==> Kam-bod-scha (has been corrected) but: Kam-bo-ds* ==> Kam-bo-dscha (has been accepted )
An exception not ending with an * will be found if it is equal, or up to three
characters shorter than the word to be hyphenated.Example: lau-f ==> lauf lau-fe lau-fen lau-fend. but not: laufende (4 characters longer !).
The length of an exception ending with ) must be equal to word length.Example: pre-cede) ==> pre-cede but not: prec-e-dence, pre-ced-ent
Following characters are permitted in exceptionsLetters: xXyY All characters are allowed in both upper and lower case. Special characters: * exception abbreviation : lau-f* ==> lau-fen-den ) exception length fixed : lauf) ==> lauf but: lau-fe - hyphen : Tren-nun-gen ==> Tren-nun-gen + hyphen with addition : Voll+a* ==> Voll-la-den... # hyphen with elimination: Taxie#tje ==> Taxi-tje . any vowel : Zei-t.n ==> Zei-ten Zei-tung , any consonant : lo-,en ==> lo-ben lo-ten ' apostrophe : c'est
Numbers 1 to 5 may be inserted instead of, or following the hyphen
in order to define the hyphenation and its quality ranking.Example: auto1mo5bile or: auto-1mo-5bile
Hyphen characters + and # may not be replaced by quality ranking numbers.
Definition of their quality ranking is done by logic automatically !
Example exception produces following word splitting ------------------------------------------------ vill+ad vill-laden vill-ladung ( 3rd L is added) but: vil-la-den-de ( > 3 characters follow !) vel-la-den ( other spelling !) vall+ad* vall-la-den-der ( 3rd L is added, remainder hyph. by logic) taxie#tje taxi-tje ( elimination of e ) but: te-xiet-je ( other spelling !) st.,,- stopp-end Stach-eln but: spuc-ken ( other spelling !) ( German c-k is changed to k-k by textsystem !)
The special hyphen signs + and # are language-dependent !
Letter addition + only operates for languages with corresponding grammatical
rules e.g. in German.
During word processing several exception files may be used simultaneously:
Standard file is always searched first (if not switched off).
DIHYPH file names must always start with letters dh e.g. "dhspec
DIHYPH standard exception file automatically used is dhex??.txt
Special exception file is searched after a word could not be found in standard
Special exception file name is defined by user in file DHDFLT.CFG
or is stored into array "exfile[ ]" by textsystem (see: DHDEF.C or DHEXT.H)
without extension !
The first special exception file name defined is preceded by key character + or ="+filename" Standard file plus this file are used. "+" Standard file only is used. "=filename" Only this file is used without standard file. "=" No exception file is used.
Several special exception files are seperated by 'space'-character:
"+file1 file2" Standard file + file1 + file2 are used in this sequence.
"=file1 file2" Only file1 and file2 are used.
Switching on/off exception files during runtime is only possible if the special
exception file(s) are defined before first calling the exception program as follows:
To change access to standard- or special-exception files, the following values
may be set into array "exfile[ ]" during runtime after the first call:"++" Standard- plus special-exception file(s) are used. "=+" Only special-exception file(s) is/are used. "+" Only standard-exception file is used. "=" No exception file is used.
Every change of program (DIHYPH, DITECT or language) is treated as first call!
DMEXCAT.EXE exception program
Before DIHYPH or DITECT may use an exception file an access catalog "exfile.CAT"
for exception file "exfile.TXT" must be created by program DMEXCAT.EXE .
For Unicode following program modules are needed:
DMCREPUC.C together with file
If only 1-byte-code is used these three DM????UC files may be replaced by
dummy file DMCREPUD.C
DMEXCAT.EXE is started with following parameters:Program call Meaning ---------------------- --------------------------------------------- DMEXCAT nn h for DIHYPH ( b DHEXnn.TXT =Default ) DMEXCAT nn t for DITECT ( b DTEXnn.TXT =Default ) DMEXCAT nn h b 1B-File for DIHYPH with 1-Byte-Code special file DMEXCAT nn t u UC-File for DITECT with Unicode special file DMEXCAT nn t 8 U8-File for DITECT with Utf-8-code special file | | | |_____ Name of special exception file (without .txt) | | | | | |_________ b = 1-Byte-Code exception file (default) | | u = Unicode exception file | | 8 = Utf-8 code exception file | | | |___________ h = DIHYPH exception file | t = DITECT exception file | |_____________ nn= language-no. 1-99
Before the catalog is created DMEXCAT.EXE does following operations:
Exceptions are automatically checked and wrong words are marked with an error
message enclosed in ' ... '.
Finally an appropriate message is displayed.
Using text editor's "search-function", errors enclosed in ' may now be jumped at
directly to correct the errors (the ' error message ' adapted to the erroneous
word is later eliminated by the program automatically).
Double storing of exceptions is automatically suppressed by the program.
When no errors are found, exceptions are stored ready-sorted and the direct-
access catalog is created to be used by DIHYPH or DITECT.
DMEXINCT.C may be used by the publishing system to immediately insert a
new exception word in exception file and to automatically create the catalog.
This tool must not be used by clients when exception file is on the server !
Header lines of DMEXINCT.c file show how to use the program.
