Hi fedora-devel, I would like to contribute a piece of bash code that handles url in gnome for ssh and telnet schemas. The idea being that whenever a user clicks a link the proper client opens up in the default terminal window configured in the user's "Preferred Applications" dialog. examples of links: telnet://my.telnet.server/ ssh://root@xxxxxxxxxxxxxx:2222/ I am not quite sure what upstream should look like for such a script. I took some of my code from launchmail which is a somewhat similar script for email but has no upstream (that I can tell). The xdg-open script from the portland/xdg-utils package is a wrapper that only calls the corresponding Desktop startup tool. In the case of gnome it calls gnome-open with the url passed to xdg-open. Only issue is that gnome-open does not support telnet or ssh. I appreciate any direct feedback on the below script and suggestions for upstream location. __ Eric $ cat terminal-url-handler #!/bin/bash # to enable URL handling in FF, open the about:config page and add a new string: # network.protocol-handler.app.telnet with value: /path/to/handler/terminal-url-handler # then add 2 new boolean: # network.protocol-handler.external.telnet and set to true # network.protocol-handler.external.ssh and set to true # last, select "always ask" for content type telnet in Firefox Preferences | Applications dialog # the first time you use the handler manually select the script file and check the remember option # # to enable this handler in gnome make sure you create the following values in gconf: # gconftool-2 -s /desktop/gnome/url-handlers/ssh/command '/path/to/terminal-url-handler %s' --type String # gconftool-2 -s /desktop/gnome/url-handlers/ssh/enabled --type Boolean true # gconftool-2 -s /desktop/gnome/url-handlers/ssh/needs_terminal --type Boolean false # gconftool-2 -s /desktop/gnome/url-handlers/telnet/command '/path/to/terminal-url-handler %s' --type String # gconftool-2 -s /desktop/gnome/url-handlers/telnet/enabled --type Boolean true # gconftool-2 -s /desktop/gnome/url-handlers/telnet/needs_terminal --type Boolean false # # URI parsing function # taken from http://valeriu.palos.ro/537/uri-parsing-using-bash-built-in-features/ # # The function creates global variables with the parsed results. # It returns 0 if parsing was successful or non-zero otherwise. # # [schema://][user[:password]@]host[:port][/path][?[param=value]...][#fragment] # uri_parser () { # uri capture uri="$@" # safe escaping uri="${uri//\`/%60}" uri="${uri//\"/%22}" # top level parsing pattern='^(([a-z]{3,6})://)?((([^:\/]+)(:([^@\/]*))?@)?([^:\/?]+)(:([0-9]+))?)(\/[^?]*)?(\?[^#]*)?(#.*)?$' [[ "$uri" =~ $pattern ]] || return 1; # component extraction uri=${BASH_REMATCH[0]} uri_schema=${BASH_REMATCH[2]} uri_address=${BASH_REMATCH[3]} uri_user=${BASH_REMATCH[5]} uri_password=${BASH_REMATCH[7]} uri_host=${BASH_REMATCH[8]} uri_port=${BASH_REMATCH[10]} uri_path=${BASH_REMATCH[11]} uri_query=${BASH_REMATCH[12]} uri_fragment=${BASH_REMATCH[13]} # path parsing count=0 path="$uri_path" pattern='^/+([^/]+)' while [[ $path =~ $pattern ]]; do eval "uri_parts[$count]=\"${BASH_REMATCH[1]}\"" path="${path:${#BASH_REMATCH[0]}}" let count++ done # query parsing count=0 query="$uri_query" pattern='^[?&]+([^= ]+)(=([^&]*))?' while [[ $query =~ $pattern ]]; do eval "uri_args[$count]=\"${BASH_REMATCH[1]}\"" eval "uri_arg_${BASH_REMATCH[1]}=\"${BASH_REMATCH[3]}\"" query="${query:${#BASH_REMATCH[0]}}" let count++ done # return success return 0 } error_dialog () { echo "$1" if [ -x /usr/bin/zenity ]; then /usr/bin/zenity --error --text="$1" else xmessage "$1" fi } sanity_check () { unset INVALID echo "$1" | grep -q "terminal-url-handler" && INVALID="yes" echo "$1" | grep -q "gnome-open" && INVALID="yes" if [ "$INVALID" == "yes" ]; then error_dialog "Error: $1 is an invalid terminal.
