From: Abhra303 <chakrabortyabhradeep79@xxxxxxxxx> Usage strings for git (sub)command flags has a style guide that suggests - first letter should not capitalized (unless requied) and it should skip full-stop at the end of line. But there are some files where usage-strings do not follow the above mentioned guide. Moreover, there are no checks to verify if all usage strings are following the guide/convention or not. Amend the usage strings that don't follow the convention/guide and add a check in the `parse_options_check()` function in `parse-options.c` to check the usage strings against the style guide. Signed-off-by: Abhradeep Chakraborty <chakrabortyabhradeep79@xxxxxxxxx> --- add usage-strings ci check and amend remaining usage strings This patch series completely fixes #636. The issue is about amending the usage-strings (for command flags such as -h, -v etc.) which do not follow the style convention/guide. There was a PR [https://github.com/gitgitgadget/git/pull/920] addressing this issue but as Johannes [https://github.com/dscho] said in his comment [https://github.com/gitgitgadget/git/issues/636#issuecomment-1018660439], there are some files that still have those kind of usage strings. Johannes also suggested to add a CI check under ci/test-documentation.sh to check the usage strings. So, in this patch, all remaining usage strings are corrected. I also added checks to parse_options_check() in parse-options.c (as suggested by Ævar). Changes since v1: 1. remove check-usage-strings.sh 2. remove CI check 3. add checks to parse-options.c 4. modify t/t1502-rev-parse-parseopt.sh to pass the test Published-As: https://github.com/gitgitgadget/git/releases/tag/pr-1147%2FAbhra303%2Fusage_command_amend-v2 Fetch-It-Via: git fetch https://github.com/gitgitgadget/git pr-1147/Abhra303/usage_command_amend-v2 Pull-Request: https://github.com/gitgitgadget/git/pull/1147 Range-diff vs v1: 1: ea0ba45d77a ! 1: 902937e768d add usage-strings ci check and amend remaining usage strings @@ Metadata Author: Abhra303 <chakrabortyabhradeep79@xxxxxxxxx> ## Commit message ## - add usage-strings ci check and amend remaining usage strings + add usage-strings check and amend remaining usage strings Usage strings for git (sub)command flags has a style guide that suggests - first letter should not capitalized (unless requied) @@ Commit message are following the guide/convention or not.
