@cindex auto correction
@cindex typo correction
@cindex spello correction
ponysay is able to auto correct misspelled pony names and balloon style name.
Without consideration for transpositioning, the distance between two words are
measured in the number of edits needed to get from one word to the other, with
weighting on some character changes used to favour spellos over typos.
By default if the weighted distance is greater than 5 for the closest words,
auto correction ignored. This limit can be changed by exporting the limit to
@env{PONYSAY_TYPO_LIMIT}; setting the limit to zero will disable auto correction.
@item @env{PONYSAY_WRAP_HYPHEN}
@vindex @env{PONYSAY_WRAP_HYPHEN}
@cindex wrapping
You can export what ponysay should use instead of a hyphen when wrapping messages.
The hythen is red by default, if you want to change the colour or other formating,
should should do so using the option @option{--colour-hyphen} (@option{--colour-wrap}).
