Following patches will teach git-submodule a new subcommand 'summary' to show commit summary of user-cared (i.e. checked out) submodules between a given super project commit (default HEAD) and working tree (or index, switched by --cached). This patch just introduces the framework and shows submodules modified as follows. -------------------------------------------- $ git submodule summary # Submodules modifiled: sm1 sm2 sm3 sm4 sm5 # -------------------------------------------- Signed-off-by: Ping Yin <pkufranky@xxxxxxxxx> --- git-submodule.sh | 66 +++++++++++++++++++++++++++++++++++++++++++++++++---- 1 files changed, 61 insertions(+), 5 deletions(-) diff --git a/git-submodule.sh b/git-submodule.sh index a6aaf40..787d083 100755 --- a/git-submodule.sh +++ b/git-submodule.sh @@ -4,7 +4,7 @@ # # Copyright (c) 2007 Lars Hjemli -USAGE='[--quiet] [--cached] [add <repo> [-b branch]|status|init|update] [--] [<path>...]' +USAGE='[--quiet] [--cached] [add <repo> [-b branch]|status|init|update|summary [<commit>]] [--] [<path>...]' OPTIONS_SPEC= . git-sh-setup require_work_tree @@ -320,7 +320,63 @@ set_name_rev () { ) ) test -z "$revname" || revname=" ($revname)" } +# +# Show commit summary for submodules in index or working tree +# +# If '--cached' is given, show summary between index and given commit, +# or between working tree and given commit +# +# $@ = [commit (default 'HEAD'),] requested paths (default all) +# +cmd_summary() { + # parse $args after "submodule ... summary". + while test $# -ne 0 + do + case "$1" in + --cached) + cached="$1" + ;; + --) + shift + break + ;; + -*) + usage + ;; + *) + break + ;; + esac + shift + done + if rev=$(git rev-parse --verify "$1^0" 2>/dev/null) + then + head=$rev + shift + else + head=HEAD + fi + + cd_to_toplevel + # Get modified modules cared by user + modules=$(git diff-index $cached --raw $head -- "$@" | + grep -e '^:160000' -e '^:[0-7]* 160000' | + while read mod_src mod_dst sha1_src sha1_dst status name + do + # Always show modules deleted or type-changed (blob<->module) + test $status = D -o $status = T && echo "$name" && continue + # Also show added or modified modules which are checked out + GIT_DIR="$name/.git" git-rev-parse --git-dir >/dev/null 2>&1 && + echo "$name" + done + ) + + # TODO: quote module names containing space or tab + test -n "$modules" && + echo "# Submodules modified: "$modules && + echo "#" +} # # List all submodules, prefixed with: # - submodule not initialized @@ -391,7 +447,7 @@ cmd_status() while test $# != 0 && test -z "$command" do case "$1" in - add | init | update | status) + add | init | update | status | summary) command=$1 ;; -q|--quiet) @@ -406,7 +462,7 @@ do branch="$2"; shift ;; --cached) - cached=1 + cached="$1" ;; --) break @@ -430,8 +486,8 @@ then usage fi -# "--cached" is accepted only by "status" -if test -n "$cached" && test "$command" != status +# "--cached" is accepted only by "status" and "summary" +if test -n "$cached" && test "$command" != status -a "$command" != summary then usage fi -- 1.5.4.3.347.g5314c -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
