+# Right click to plumb
+
+Pretty much like plan9's acme and plumber: right-click some selected text to send it to the plumbing program of your choosing:
+
+- open an URL in a browser
+- view an image, PDF, ...
+- jump from logs to editor, at the specified line/col
+- etc
+
+The shell current working directory is set by the shell via `OSC 7` (borrowed from vte, see `/etc/profile.d/vte.sh` if you have it installed).
+
+For zsh :
+
+```sh
+__vte_urlencode() (
+  # This is important to make sure string manipulation is handled
+  # byte-by-byte.
+  LC_ALL=C
+  str="$1"
+  while [ -n "$str" ]; do
+    safe="${str%%[!a-zA-Z0-9/:_\.\-\!\'\(\)~]*}"
+    printf "%s" "$safe"
+    str="${str#"$safe"}"
+    if [ -n "$str" ]; then
+      printf "%%%02X" "'$str"
+      str="${str#?}"
+    fi
+  done
+)
+
+__vte_osc7 () {
+  printf "\033]7;%s%s\a" "${HOSTNAME:-}" "$(__vte_urlencode "${PWD}")"
+}
+
+[ -n "$ZSH_VERSION"  ] && precmd_functions+=(__vte_osc7)
+```
+
+The patch itself only adds a `cwd` global and a button3 entry that will run a shell, change directory to cwd and run the plumber with the primary selection. Maybe I should use pass cwd as an argument too, like plan9 plumber does.
+
+The plumbing program can be defined via `config.h`: 
+
+```h
+static char plumber[] = "plumb.sh";
+```
