The shell completion scripts in "contrib/completion" are being tested, but none of our build systems support installing them. This is somewhat confusing for Meson, where users can explicitly enable building these scripts via `-Dcontrib=completion`. This option only controlls whether the completions are built and tested against, where "building" is a bit of an euphemism for "copying them into the build directory". Teach both our Makefile and Meson to install our Bash completion script. For now, this is the only completion script that we're installing given that Bash completions "just work" with a canonical well-known location nowadays. Other completion scripts, like for example the one for zsh, don't have a well-known location and/or require extra steps by the user to make them available. As such, we skip installing these scripts for now, but we may do so in the future if we ever figure out a proper way to do this. Signed-off-by: Patrick Steinhardt <ps@xxxxxx> --- Hi, this patch is a result from the discussion at [1]. Thanks! Changes in v2: - Only install Bash completion for now. - Also install Bash completion via our Makefile. - Link to v1: https://lore.kernel.org/r/20250407-b4-pks-meson-install-completions-v1-1-8a7eb8b9284b@xxxxxx Patrick [1]: <Z-uLqQd7QHZq-tB7@xxxxxxxxx> --- Makefile | 6 ++++++ contrib/completion/meson.build | 18 ++++++++++++++++++ 2 files changed, 24 insertions(+) diff --git a/Makefile b/Makefile index ac32d2d0bda..118592414b5 100644 --- a/Makefile +++ b/Makefile @@ -618,6 +618,7 @@ prefix = $(HOME) bindir = $(prefix)/bin mandir = $(prefix)/share/man infodir = $(prefix)/share/info +bash_completion_dir = $(prefix)/share/bash-completion/completions gitexecdir = libexec/git-core mergetoolsdir = $(gitexecdir)/mergetools sharedir = $(prefix)/share @@ -2321,6 +2322,7 @@ bindir_relative_SQ = $(subst ','\'',$(bindir_relative)) mandir_SQ = $(subst ','\'',$(mandir)) mandir_relative_SQ = $(subst ','\'',$(mandir_relative)) infodir_relative_SQ = $(subst ','\'',$(infodir_relative)) +bash_completion_dir_SQ = $(subst ','\'',$(bash_completion_dir)) perllibdir_SQ = $(subst ','\'',$(perllibdir)) localedir_SQ = $(subst ','\'',$(localedir)) localedir_relative_SQ = $(subst ','\'',$(localedir_relative)) @@ -3565,6 +3567,10 @@ endif ifneq (,$X) $(foreach p,$(patsubst %$X,%,$(filter %$X,$(ALL_COMMANDS_TO_INSTALL) $(OTHER_PROGRAMS))), test '$(DESTDIR_SQ)$(gitexec_instdir_SQ)/$p' -ef '$(DESTDIR_SQ)$(gitexec_instdir_SQ)/$p$X' || $(RM) '$(DESTDIR_SQ)$(gitexec_instdir_SQ)/$p';) endif +ifndef NO_BASH_COMPLETION + $(INSTALL) -d -m 755 '$(DESTDIR_SQ)$(bash_completion_dir_SQ)' && \ + $(INSTALL) -m 644 contrib/completion/git-completion.bash '$(DESTDIR_SQ)$(bash_completion_dir_SQ)/git' +endif bindir=$$(cd '$(DESTDIR_SQ)$(bindir_SQ)' && pwd) && \ execdir=$$(cd '$(DESTDIR_SQ)$(gitexec_instdir_SQ)' && pwd) && \ diff --git a/contrib/completion/meson.build b/contrib/completion/meson.build index 3a9ddab5940..576125b083d 100644 --- a/contrib/completion/meson.build +++ b/contrib/completion/meson.build @@ -14,3 +14,21 @@ foreach script : [ ) endif endforeach + +# We have to discern between the test dependency and the installed file.
