- 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
