[pacman-dev] [PATCH] contrib/pactree: generate reverse dependency trees
From: Christophe Chapuis <chris.chapuis@gmail.com> Add an option to show the tree of packages which depend on a given package Signed-off-by: Allan McRae <allan@archlinux.org> --- Just a git diff from Christophe's original patch. I adjusted the patch slightly so that the original was the first path in the if/else statements. Also bumped pkgver a larger version. contrib/pactree | 31 ++++++++++++++++++++++++++----- 1 files changed, 26 insertions(+), 5 deletions(-) diff --git a/contrib/pactree b/contrib/pactree index df53671..73bece3 100755 --- a/contrib/pactree +++ b/contrib/pactree @@ -41,7 +41,7 @@ arrow1_color="chocolate4" #color of the normal arrow arrow2_color="grey" #color of the "provided by" headless arrow readonly prog_name="pactree" -readonly prog_ver="0.2" +readonly prog_ver="0.3" _usage(){ echo "This program generates the dependency tree of an installed package" @@ -52,13 +52,14 @@ _usage(){ echo " -d, --depth INT Limit the shown dependencies depth" echo " -g, --graph Use graphviz to make an image of the tree" echo " -l, --linear Enable linear output" + echo " -r, --reversed Show reversed dependancies" echo " -s, --silent Shh, let me hear those errors!" echo " -u, --unique Print the dependency list with no duplicates" echo echo " -h, --help Print this help message" echo " -v, --version Print the program name and version" echo - echo "Example: $prog_name -c -d 2 readline" + echo "Example: $prog_name -c -d2 readline" } _version(){ @@ -140,7 +141,16 @@ _tree(){ if [[ !
