This is GNU ISPELL V3, an interactive spelling corrector based on ITS SPELL.
DOCUMENTATION:
See the man page 'ispell.1' and the file 'ispell.texinfo'.
INSTALLATION:
1. Configure Ispell for your system. In the directory that this file
is in, type `./configure'. If you're using `csh' on an old version of
System V, you might need to type `sh configure' instead to prevent
`csh' from trying to execute `configure' itself.
The `configure' shell script attempts to guess correct values for
various system-dependent variables used during compilation, and
creates the Makefile(s) (one in each subdirectory of the source
directory). In some packages it creates a C header file containing
system-dependent definitions. It also creates a file `config.status'
that you can run in the future to recreate the current configuration.
Running `configure' takes a minute or two. While it is running, it
prints some messages that tell what it is doing. If you don't want to
see the messages, run `configure' with its standard output redirected
to `/dev/null'; for example, `./configure >/dev/null'.
To compile the package in a different directory from the one
containing the source code, you must use a version of `make' that
supports the VPATH variable, such as GNU `make'. `cd' to the
directory where you want the object files and executables to go and
run `configure'. `configure' automatically checks for the source code
in the directory that `configure' is in and in `..'. If for some
reason `configure' is not in the source code directory that you are
configuring, then it will report that it can't find the source code.
In that case, run `configure' with the option `--srcdir=DIR', where
DIR is the directory that contains the source code.
By default, `make install' will install the Ispell files in
/usr/local/bin, /usr/local/lib, /usr/local/man, etc. You can specify
an installation prefix other than /usr/local by giving `configure' the
option `--prefix=PATH'. Alternately, you can do so by giving a value
for the `prefix' variable when you run `make', e.g.,
make prefix=/usr/gnu
You can specify separate installation prefixes for
architecture-specific files and architecture-independent files. If
you give `configure' the option `--exec-prefix=PATH' or set the `make'
variable `exec_prefix' to PATH, the package will use PATH as the
prefix for installing programs and libraries. Data files and
documentation will still use the regular prefix. Normally, all files
are installed using the regular prefix.
Another `configure' option is useful mainly in `Makefile' rules for
updating `config.status' and `Makefile'. The `--no-create' option
figures out the configuration for your system and records it in
`config.status', without actually configuring the package (creating
`Makefile'). Later, you can run `./config.status' to actually
configure the package. You can also give `config.status' the
`--recheck' option, which makes it re-run `configure' with the same
arguments you used before. This option is useful if you change
`configure'.
`configure' ignores any other arguments that you give it.
If your system requires unusual options for compilation or linking
that `configure' doesn't know about, you can give `configure' initial
values for some variables by setting them in the environment. In
Bourne-compatible shells, you can do that on the command line like
this:
CC='gcc -traditional' DEFS=-D_POSIX_SOURCE ./configure
The `make' variables that you might want to override with environment
variables when running `configure' are:
(For these variables, any value given in the environment overrides the
value that `configure' would choose:)
CC C compiler program.
Default is `cc', or `gcc' if `gcc' is in your PATH.
INSTALL Program to use to install files.
Default is `install' if you have it, `cp' otherwise.
(For these variables, any value given in the environment is added to
the value that `configure' chooses:)
DEFS Configuration options, in the form `-Dfoo -Dbar ...'
LIBS Libraries to link with, in the form `-lfoo -lbar ...'
If you need to do unusual things to compile the package, we encourage
you to figure out how `configure' could check whether to do them, and
mail diffs or instructions to the address given in the README so we
can include them in the next release.
2. Type `make' to compile the package. If you want, you can override
the `make' variables CFLAGS and LDFLAGS like this:
make CFLAGS=-O2 LDFLAGS=-s
3. Type `make install' to install programs, data files, and
documentation.
The files that get installed are (directories vary):
/usr/local/lib/ispell/ispell.dict
/usr/local/lib/ispell/ispell.words
/usr/local/bin/ispell
/usr/local/bin/look
/usr/local/lib/elisp/ispell.el
/usr/local/lib/elisp/ispell.elc
/usr/local/lib/emacs/info/ispell
/usr/local/man/man1/ispell.1
4. You can remove the program binaries and object files from the
source directory by typing `make clean'. To also remove the
Makefile(s), the header file containing system-dependent definitions
(if the package uses one), and `config.status' (all the files that
`configure' created), type `make distclean'.
The file `configure.in' is used as a template to create `configure' by
a program called `autoconf'. You will only need it if you want to
regenerate `configure' using a newer version of `autoconf'.
ADDING WORDS TO THE DICTIONARY:
You must remove unwanted punctuation from the word list before
using it with ispell. It is ok to leave in apostrophes, but
other non-alphabetic characters are not desirable. Anything
that you do leave in will be used in near miss generation, and
in the parser. For example, if the word list contains a hyphen
in any entry, then the parser will always consider hyphen a
part of a word, and strings like 'two-character' will get looked
up as one word.
However, since the character set is determined by scanning the
word list, it automatically handles single byte international
characters. If you use or extend these new parts of ispell,
please let us know.
The flags in the dictionary must be set up by the program itself.
See the node "Dictionary flags" in the info file for details.
The way to do this is:
cat dictionary files ... > dict0
freq < dict0 > freqtbl
build -a -r -f freqtbl -o dict dict0
build -b -f freqtbl -o ispell.dict dict
The input files may have flags, but do not have to, and they do not
need to be sorted. The '-r' (reap) flag to build means to try to
replace entries with flags on other entries. The '-a' flag means to
write the output in ascii. After the first build run, the file 'dict'
contains all of the input words, but with the flags correctly set.
The second one is the same as the one in the makefile.
The hash table used by build and ispell cannot contain more than about
64K root words at one time. You can have many more words in the dictionary
because of the flags; however, you have to bootstrap a random word list
in smaller chunks:
freq < wordlist > freqtbl
split -60000 wordlist
cp /dev/null d0
for i in x??
do
build -a -r -f freqtbl -o tmp $i
cat tmp >> d0
done
build -a -r -f freqtbl -o dict d0
build -b -f freqtbl -o ispell.dict dict
