To people who received the last post and got a bit annoyed at the
lack of a makefile, I apologise. It was my first net posting. I'll
know better next time. Meanwhile here's an emergency fix;
cc dawg.c; mv a.out dawg
cc pdawg.c; mv a.out pdawg
cc pack.c; mv a.out pack
cc ppack.c; mv a.out ppack
cc dwgcheck.c; mv a.out dwgcheck
cc pckcheck.c; mv a.out pckcheck
cc tell.c; mv a.out tell
cc proot.c; mv a.out proot
dawg /usr/dict/words dict
pack dict.dwg dict.pck
dwgcheck this and that wroang wurd and another wurd
pckcheck this and that wroang wurd and another wurd
proot meta
tell stoopid speled wurds
Hope that helps a bit. Now for todays additions:
cc typo.c; mv a.out typo
cc cross.c; mv a.out cross
typo spel
cross p\?zz\?e
#!/bin/sh-----cut here-----cut here-----cut here-----cut here-----
# shar: Shell Archiver
# Run the following text with /bin/sh to create:
# README # cross.c # typo.c
cat - << \SHAR_EOF > README
This is probably rather early for a follow up to my posting on
spelling checker utilities, but a couple of people have asked for
these...
(These programs need dawgutils/* as posted a couple of days ago)
typo.c
A sample program showing how to use the dawg structure to efficiently
correct typos.
cross.c
A 'crossword puzzle' solver - effectively the same as grepping the
word list allowing '?' as a single wild char, eg cross p?zz?e
would return 'puzzle'.
I've also had some interest in my throwaway comments on a replacement
for Soundex; enough to convince me to document it properly and post it
here (a week away at the earliest). Meanwhile, may I ask again:
If anyone has a dictionary of words and their phonetic representations
could they get in touch please? Many thanks if you can.
Share & Enjoy,

Description:
Like the unix 'spelltell' command but only fixes typos
rather than soundslike errors.
See my 'tell' program if you want soundex, or wait a few weeks
for my new proper phonetic algorithm.
It is a design decision that some of the functions will return the word
presented if it is in fact correct. You can call this a bug if you
prefer.
(The nice thing about the dawg structure is that it makes utilities
like this easy to write; none of these small programs has taken
more than about an hour.)
