SYNOPSIS
| |
dict [ −k ] [ −d dictname ] [ −c command ] [ pattern ] adict [
−d dictname ] [ pattern ]
|
DESCRIPTION
| |
Dict is a dictionary browser. If a pattern is given on the command
line, dict prints all matching entries; otherwise it repeatedly
accepts and executes commands. The options are
−d dictname Use the given dictionary. A list of available dictionaries
is printed by option −d?. The default is the first dictionary
on the list that is installed on the system.
−c command Execute one command and quit. The command syntax is
described below.
−k Print a pronunciation key.
Patterns are regular expressions (see regexp(7)), with an implicit
leading ^ and trailing $. Patterns are matched against an index
of headwords and variants, to form a ‘match set’. By default,
both patterns and the index are folded: upper case characters
are mapped into their lower case equivalents, and Latin accented
characters are mapped into their
non-accented equivalents. In interactive mode, there is always
a ‘current match set’ and a ‘current entry’ within the match set.
Commands can change either or both, as well as print the entries
or information about them.
Commands have an address followed by a command letter. Addresses
have the form:
/re/ Set the match set to all entries matching the regular expression
re, sorted in dictionary order. Set the current entry to the first
of the match set.
!re! Like /re/ but use exact matching, i.e., without case and accent
folding.
n An integer n means change the current entry to the nth of the
current match set.
#n The integer n is an absolute byte offset into the raw dictionary.
(See the A command, below.)
addr+ After setting the match set and current entry according to
addr, change the match set and current entry to be the next entry
in the dictionary (not necessarily in the match set) after the
current entry.
addr− Like addr+ but go to previous dictionary entry.
The command letters come in pairs: a lower case and the corresponding
upper case letter. The lower case version prints something about
the current entry only, and advances the current entry to the
next in the match set (wrapping around to the beginning after
the last). The upper case version prints something about all of
the match set and resets the
current entry to the beginning of the set.
p,P Print the whole entry.
h,H Print only the headword(s) of the entry.
a,A Print the dictionary byte offset of the entry.
r,R Print the whole entry in raw format (without translating special
characters, etc.).
If no command letter is given for the first command, H is assumed.
After an H, the default command is p. Otherwise, the default command
is the previous command.
Dict searches for dictionaries in the directory named by $dictpath
(default /usr/local/plan9/dict).
Adict is a dictionary browser for acme(1). When run with no arguments,
it creates a new acme window named /adict/ listing the installed
dictionaries. Clicking with button 3 on a dictionary name will
create a new empty window named /adict/dict/. Typing and then
clicking on a pattern in this window will create a new lookup
window named
/adict/dict/pattern containing the dictionary’s definition of
pattern. Clicking with button 3 on any word in this new window
will create new lookup windows.
If adict is run with a pattern , it starts with the /adict/dict/pattern
window.
If adict is run with no pattern but with a −d option, it starts
with the /adict/dict/ window.

BUGS
| |
A font with wide coverage of the Unicode Standard should be used
for best results. (Try /usr/local/plan9/font/pelm/unicode.9.font.)
If the pattern doesn’t begin with a few literal characters, matching
takes a long time.
The dictionaries are not distributed outside Bell Labs, though
see /usr/local/plan9/dict/README for information on using free
dictionaries prepared by Project Gutenberg.
