default-spell-options: preference variable

Default value: 0

This variable controls the Spell minor mode in those modes that don't have a dedicated variable for spelling.

Epsilon puts -spell-options after the major mode's name and looks for a variable by that name. If none, it uses this variable to see if it should highlight misspelled words. Use the spell-mode command to set it to 1, and Epsilon will highlight misspelled words in all such modes.

All -spell-options variables contain these bits, which you can set to customize how spell checking works:

Bit   Meaning

0x1   Highlight misspelled words.

0x2   Skip words containing an underscore.

0x4   Skip MixedCaseWords (those with internal capitalization).

0x8   Skip uppercase words (those with no lowercase letters).

0x10   Skip words following a digit, like 14th.

0x20   Skip words before a digit, like gr8.

0x200   Don't remove 's when checking words.

0x1000   Provide faster but less accurate built-in suggestions.

0x2000   Don't copy the case of the original in built-in suggestions.

0x4000   Add globally ignored words to spell helper's list.

When the spell-helper-program variable is nonempty so that Epsilon gets its suggestions by running an external program, it ignores the 0x10 and 0x20 bits.
