  -e, --excludeSource   is with exclude source file
  -x, --extract         extract manifest file from jar
  -f, --filter string   filter
  -h, --help            help for manifest
  -m, --merge           is merge package
  -p, --path string     path (default ".")
  -s, --scan            scan manifest file to graphviz
  -v, --version         show manifest version info of jar

examples:

merry manifest -s -x -f org.eclipse.equinox -p ~/sdk/equinox-SDK-4.15/plugins

Generate Pom from jars

merry pom -p _fixtures/demo -m _fixtures/map/map.csv

Call Graph by Manifest.MF

Flags:
  -h, --help          help for call
  -m, --map string    map file
  -p, --path string   path (default ".")
  -s, --server        with server

full steps:

merry manifest -s -p ~/sdk/apache-karaf-4.2.9/lib/boot  -x
merry map -p ~/sdk/apache-karaf-4.2.9/lib/boot
merry call -p ~/sdk/apache-karaf-4.2.9/lib/boot -m map.csv

results:

show only one line with strict

strict digraph G {
  a -> b [ label = "foo" ];
  a -> b [ label = "bar" ];
}

Call Server

cmd: merry call -s

merry will read manifest-map.json and start to http://localhost:3000:
