The help command currently hard codes the list of guides and their summary in C. Let's move this list to command-list.txt. This lets us extract summary lines from Documentation/git*.txt. This also potentially lets us list guides in git.txt, but I'll leave that for now. --- Documentation/gitattributes.txt | 2 +- Documentation/gitmodules.txt | 2 +- Documentation/gitrevisions.txt | 2 +- Makefile | 2 +- builtin/help.c | 32 -------------------------- command-list.txt | 16 +++++++++++++ contrib/completion/git-completion.bash | 15 ++++++++---- help.c | 21 +++++++++++++---- help.h | 1 + t/t0012-help.sh | 6 +++++ 10 files changed, 54 insertions(+), 45 deletions(-) diff --git a/Documentation/gitattributes.txt b/Documentation/gitattributes.txt index 1094fe2b5b..083c2f380d 100644 --- a/Documentation/gitattributes.txt +++ b/Documentation/gitattributes.txt @@ -3,7 +3,7 @@ gitattributes(5) NAME ---- -gitattributes - defining attributes per path +gitattributes - Defining attributes per path SYNOPSIS -------- diff --git a/Documentation/gitmodules.txt b/Documentation/gitmodules.txt index db5d47eb19..4d63def206 100644 --- a/Documentation/gitmodules.txt +++ b/Documentation/gitmodules.txt @@ -3,7 +3,7 @@ gitmodules(5) NAME ---- -gitmodules - defining submodule properties +gitmodules - Defining submodule properties SYNOPSIS -------- diff --git a/Documentation/gitrevisions.txt b/Documentation/gitrevisions.txt index 27dec5b91d..1f6cceaefb 100644 --- a/Documentation/gitrevisions.txt +++ b/Documentation/gitrevisions.txt @@ -3,7 +3,7 @@ gitrevisions(7) NAME ---- -gitrevisions - specifying revisions and ranges for Git +gitrevisions - Specifying revisions and ranges for Git SYNOPSIS -------- diff --git a/Makefile b/Makefile index a60a78ee67..1efb751e46 100644 --- a/Makefile +++ b/Makefile @@ -1937,7 +1937,7 @@ $(BUILT_INS): git$X command-list.h: generate-cmdlist.sh command-list.txt -command-list.h: $(wildcard Documentation/git-*.txt) +command-list.h: $(wildcard Documentation/git*.txt) $(QUIET_GEN)$(SHELL_PATH) ./generate-cmdlist.sh command-list.txt >$@+ && mv $@+ $@ SCRIPT_DEFINES = $(SHELL_PATH_SQ):$(DIFF_SQ):$(GIT_VERSION):\ diff --git a/builtin/help.c b/builtin/help.c index 0e0af8426a..5727fb5e51 100644 --- a/builtin/help.c +++ b/builtin/help.c @@ -402,38 +402,6 @@ static void show_html_page(const char *git_cmd) open_html(page_path.buf);
