LCB Wrapper around Hunspell

This repo contains version 1.6.2 of Hunspell for 32-bit and 64-bit Windows. The hunspell.lcb file wraps these DLLs and provides an API for doing the following:

• Spell checking a word
• Getting suggested words for a misspelled word
• Adding a word to the in-memory dictionary
• Removing a word from the in-memory dictionary

The hunspell.livecodescript file is intended to be used as a library. It provides the hunspellFindMisspelledWords function which will spell check a run of text and returns character ranges for all misspelled words. The return value can be assigned to the flaggedRanges property of a field.

Dictionaries

A French dictionary is included for testing purposes. Dictionaries in a variety of languages that are in the correct format for use with hunspell can be found in the following github repo:

Linux and macoS Support

Linux

Support can be added to this repo by compiling the hunspell library as a shared object library (.so) for both 32 and 64-bit. The 32-bit library should be added as ./code/x86-linux/libhunspell.so and the 64-bit version should be added as ./code/x86_64-linux/libhunspell.so.

macOS

macOS provides a built-in spell checker which should be used. A wrapper around NSSpellChecker for macOS can be found at the following url:

https://github.com/trevordevore/lc-macos-toolset/blob/master/NSSpellChecker/nsspellchecker.lcb

If you want to work on the extension on macOS then add a hunspell dylib to ./code/x86_64-mac/libhunspell.dylib.
