I'm having problem with french dictionaries. Loading an ispell affix
file with apostrophes does not work. The file comes from the ifrench
(french dict for ispell) debian source package at
http://packages.debian.org/sid/ifrench
Here's the session excerpt:
------------------------------------------------------------------------
Welcome to psql 8.3.3, the PostgreSQL interactive terminal.
Type: \copyright for distribution terms
\h for help with SQL commands
\? for help with psql commands
\g or terminate with semicolon to execute query
\q to quit
dockee=# select plainto_tsquery('custom_french', 'bug');
ERROR: syntax error at line 158 of affix file
"/usr/share/postgresql/8.3/tsearch_data/ispell_french.affix"
dockee=# show lc_ctype ;
lc_ctype
-------------
en_US.UTF-8

dockee=# show server_version;

------------------------------------------------------------------------
The 'custom_french' text configuration is defined as below:
------------------------------------------------------------------------
CREATE TEXT SEARCH CONFIGURATION public.custom_french ( COPY =
pg_catalog.french );
CREATE TEXT SEARCH DICTIONARY french_ispell (
TEMPLATE = ispell,
DictFile = ispell_french,
AffFile = ispell_french
);
ALTER TEXT SEARCH CONFIGURATION custom_french
ALTER MAPPING FOR
asciiword,
asciihword,
hword_asciipart,
word,
hword,
hword_part
WITH french_ispell ;
ALTER TEXT SEARCH CONFIGURATION custom_french
DROP MAPPING FOR
url,url_path,sfloat,float,file,int,version;
------------------------------------------------------------------------
Line 158 of file ispell_french.affix corresponds to the first flag
definition that triggers a prefix with an apostrophe, it's the line
below "flag *N"
------------------------------------------------------------------------
flag *D: # dé: défaire, dégrossir
. > dé
flag *N: # élision d'une négation
[aàâeèéêiîoôuh] > n' # je n'aime pas, il n'y a pas
------------------------------------------------------------------------
Maybe apostrophes in ispell affix files are simply not supported? I
can't find a mention of this limitation in the documentation at
http://www.postgresql.org/docs/8.3/static/textsearch-dictionaries.html
When commenting out the offending flag definitions, the affix file
loads successfully. Thanks in advance for helping me resolve this
problem.
