- DESCRIPTION
- AlphaSpell is mainly for spellchecking and dictionary maintenance, and
- it can perform a couple other tasks that were easy to implement and
- might be useful.
-
- SPELLCHECK
- Spellchecking is the main purpose of AlphaSpell. When
- spellchecking, AlphaSpell extracts all the words sent to it though
- standard input, translates them into lowercase, and checks them
- against an alphabetized, lowercase ascii dictionary. It sends to
- standard output any words which it could not find in the
- dictionary. The user should then find these words in the document
- that he had spellchecked and make sure these are the words he wants
- to use. On the Amiga, the user may use an ARexx script I wrote for
- this purpose.
-
- COMMON
- This works like spellchecking, except that AlphaSpell sends to
- standard output every word it did find. This may be useful when you
- want to check for problem words in a document, such as "they're,"
- "their," and "there," or "accept" and "except."
-
- MERGE
- This requires that the file sent through standard input be an
- alphabetized, lowercase ascii dictionary. It is meant for merging
- two ascii dictionaries into one. E.g., you might want to merge your
- user dictionary with your main dictionary.
-
- REMOVE
- Like MERGE, this requires that the file sent through standard input
- be a lowercase ascii dictionary. It sends to standard output all
- the words in the dictionary except those from standard input. This
- is useful for removing unwanted words from the dictionary, such as
- misspellings and jargon you'll never use. Although you could
- probably do this more easily with a text editor if you have enough
- RAM, this feature gives people without enough RAM the same ability.
-
- This feature may also be used for spellchecking alphabetized lists
- of words, as the original AlphaSpell did. When you use it for this
- purpose, you should send the dictionary through standard input and
- give the name of the file you want to spellcheck as the dictionary
- name.

- DETAILS
-
- WORDS
- A word for AlphaSpell is a string of two or more letters, which may
- have apostrophes inside but not at the ends. Words do not include
- apostrophe-s.

-
- SPELLCHECKING METHOD
- AlphaSpell spellchecks words in alphabetical order, hence its name.
- As it begins to look for each word, it begins where it left off in
- the dictionary. This allows it to quickly finish spellchecking by
- making only a single pass through the dictionary. It can thereby
- finish spellchecking in less time than it would take to load the
- dictionary into memory.
-
- HISTORY
- Before AlphaSpell and before I knew C, I had written a spelling checker
- in ARexx. I don't think I ever released this. But I used a similar
- spellchecking algorithm in AlphaSpell.
-
- I wrote the first version of AlphaSpell in C when I was first trying to
- learn the language back in the Spring of 1992. Its abilities were
- limited because my knowledge of C was limited.
-
- AlphaSpell V2.00 was also in C, but I never released it. It had the
- ability to use a compacted dictionary.
-
- AlphaSpell V3.00 is not a revision of previous versions of AlphaSpell.
- It is a new and better program written from scratch in C++. It is my
- first major C++ program. AlphaSpell uses the same basic algorithm for
- spellchecking, but it implements it with less redundancy.
-
- Previous versions would load in each word from the dictionary and use
- case insensitive comparison. AlphaSpell III spellchecks without loading
- in each word, and it uses case sensitive comparison. Thus, it zips
- through the dictionary faster than previous versions did.
-
- Also, AlphaSpell V3.00 does not depend upon the programs which previous
- versions needed. Previous versions of AlphaSpell needed their input
- prepared by the three programs getwords, sort, and uniq. AlphaSpell
- V3.00 doesn't.
-
- Unlike AlphaSpell V2.00, the unregistered version of AlphaSpell V3.00
- does not work with compacted dictionaries. But the registered version
- does.
