Description

Allows for examining or setting options that affect the behavior of the diff, match, and patch related functions in this package.

Usage

dmp_options(...)

Arguments

...

No arguments returns all current options and their values. Character values retrieve a subset of options and the current values. Options can be set, using name = value. However, only the options named below are used. Options can also be passed by giving a single unnamed argument which is a named list.

Value

When getting options returns a named list of options and their current values, when setting options returns a named list of the previous value(s).

Details

Available options

• diff_timeout (float) - Number of seconds to map a diff before giving up (0 for infinity).

• diff_edit_cost (int) - Cost of an empty edit operation in terms of edit characters.

• match_threshold (float) - At what point is no match declared (0.0 = perfection, 1.0 = very loose).

• match_distance (int) - How far to search for a match (0 = exact location, 1000+ = broad match). A match this many characters away from the expected location will add 1.0 to the score (0.0 is a perfect match).

• patch_delete_threshold (float) - When deleting a large block of text (over ~64 characters), how close does the contents have to match the expected contents. (0.0 = perfection, 1.0 = very loose). Note that Match_Threshold controls how closely the end points of a delete need to match.

• patch_margin (int) - Chunk size for context length.

• match_max_bits (int) - The number of bits in an int.
