The reason to make it consider negative values or more specifically "unspecified" values is to give the ability to differentiate between once, multiple time or with --no-option. Eg. : initialize verbose = -1 `git commit` => verbose = -1 `git commit -v` => verbose = 1 `git commit -v -v` => verbose = 2 `git commit --no-verbose` => verbose = 0 Signed-off-by: Pranit Bauva <pranit.bauva@xxxxxxxxx> --- The discussion about this patch: [1] : http://thread.gmane.org/gmane.comp.version-control.git/289027 Previous version of the patch: [v1] : http://thread.gmane.org/gmane.comp.version-control.git/289061 Changes introduced: Use a different language in commit message to make the change and its utility more clear. --- Documentation/technical/api-parse-options.txt | 6 ++++-- parse-options.c | 8 +++++++- 2 files changed, 11 insertions(+), 3 deletions(-) diff --git a/Documentation/technical/api-parse-options.txt b/Documentation/technical/api-parse-options.txt index 5f0757d..a908d8a 100644 --- a/Documentation/technical/api-parse-options.txt +++ b/Documentation/technical/api-parse-options.txt @@ -144,8 +144,10 @@ There are some macros to easily define options: `OPT_COUNTUP(short, long, &int_var, description)`:: Introduce a count-up option. - `int_var` is incremented on each use of `--option`, and - reset to zero with `--no-option`. + If the `int_var` is negative and `--option` is absent, + then it will retain its value.
