      1 # Plumber – a modern approach
      2 
      3 ## Introduction
      4 
      5 Plumber is like xdg-open(1) but much more powerful. For now it's my personal
      6 toy to help me handle all kind of URIs and speed up my daily life.

      8 ## License
      9 
     10 See the LICENSE file for the terms.
     11 
     12 ## Dependencies
     13 * Python
     14 * mailcap(1), for local file handling
     15 	* no need for duplication
     16 * There are dependencies in the openers. See the openers for their
     17   dependencies.
     18 
     19 ## Installation
     20 
     21 Installation of plumb can be done manually or via the makefile. By
     22 default it installs to `bin` inside the user's home directory (note:
     23 some plumb users find it is easiest to install plumb to
     24 `/usr/local/bin`.) After plumb is installed, you should probably add
     25 the program's location to the user's path and export environmental
     26 variables for openers.
     27 
     28 	% export PATH="$PATH:<location_of_plumb>"
     29 	% export XTERM=<your preferred_xterminal xterm?>
     30 	% export PLUMB_IMAGE=<your_preferred_image_viewer feh -F --auto-rotate?>
     31 	% export PLUMB_MEDIA=<your_preferred_mediaplayer mpv?>
     32 	% export PLUMB_GOPHER=<your_preferred_gopher_browser gopher?>
     33 	% export PLUMB_TXTGOPHER=<your_preferred_gopher_textbrowser gopher?>
     34 	% export PLUMB_PDF=<your_preferred_pdf_viewer xpdf?>
     35 	% export PLUMB_FILEMANAGER=<your_preferred_filemanager ranger?>
     36 	% export PLUMB_WEB=<your_preferred_webbrowser firefox?>
     37 	% export PLUMB_TXTWEB=<your_preferred_text_webbrowser lynx?>
     38 	% export PLUMB_FEED=<your_preferred_RSS/Atom_client thunderbird?>
     39 	% export PLUMB_WAIS=<your_preferred_WAIS_client lynx?>
     40 	% export PLUMB_CSO=<your_preferred_CSO_client lynx?>

     43 
     44 ### Manual
     45 
     46 	# Copy the symlinks you like. I use all of them.
     47 	% cp bin/plumber $HOME/bin
     48 	% cp -a bin/p $HOME/bin
     49 	% cp -a bin/plumb $HOME/bin
     50 	% cp -a bin/Þ $HOME/bin
     51 	% cp openers/* $HOME/bin
     52 	# Required for dwm integration:
     53 	% cp bin/opener $HOME/bin
     54     % export XTERM=<your_preferred_xterminal>
     55     # Add the above to your .mkshrc or .bashrc to make permanent.
     56 
     57 ### Makefile
     58 
     59 	# Install plumb to user's $HOME
     60 	% make install
     61 	# Or, install to a specific directory
     62 	% make install DESTDIR=/usr/local/bin
     63 
     64 ## Usage
     65 
     66 	% p http://www.searx.me
     67 	% echo "http://searx.me" | p
     68 	% echo -e "http://searx.me\nhttp://google.com\n" | p -me
     69 	% echo "Please go to http://searx.me please." | p -tme
     70 	# Be surprised about the ease of usage!
     71 
     72 ### st (simple terminal) integration
     73 
     74 In my setup I am calling »plumber -tme« via the externalpipe patch, applied to
     75 st mainline. The config.h would include:
     76 
     77 	{ MODKEY, XK_o, externalpipe, {.v = "plumber -tme" } },
     78 
     79 ### dwm (dynamic window manager) integration
     80 
     81 For using the plumber in dwm I have the »opener(1)« script, which gets the
     82 X11 selection and gives it to the plumber. Here is the config.h entry:
     83 
     84 	{ MODKEY, XK_o, spawn, SHCMD("opener") },
     85 
     86 This allows something really valuable: Select some text and press Mod + o,
     87 which opens the selected text. If you use double click to select some URI or
     88 text, plumber has included stripping support to shorten quotation marks or
     89 (square) brackets.
     90 
     91 ### urxvt
     92 
     93 Urxvt integrates with plumber beautifully because of urxvt-matcher.
     94 urxvt-matcher can highlight strings of interest like URLs and pass these
     95 along to plumber, where they will be opened with the assigned opener. To
     96 do this, you will need to have urxvt-matcher installed on your system.
     97 Then add the following line to your .Xresources:
     98 
     99 	URxvt.matcher.launcher: plumb $0
    100 	URxvt.matcher.button: 1
    101 
    102 Additional URLs can be matched and launched by specifying more patterns
    103 to urxvt-matcher, as below where two patterns are added for launching
    104 gopher and gophers:
    105 
    106 	URxvt.matcher.pattern.1: \\b(gopher\\:\\/\\/\\S+)\\b
    107 	URxvt.matcher.launcher.1: plumb $1
    108 	URxvt.matcher.pattern.2: \\b(gophers\\:\\/\\/\\S+)\\b
    109 	URxvt.matcher.launcher.2: plumb $1
    110 
    111 To see and select the matches, you press M-Del on your keyboard to invoke
    112 match-select. Then use the up and down arrows to move between matches.
    113 Press enter to send a selected match to plumb.
    114 
    115 ## Openers
    116 
    117 The distribution includes nearly all openers I have written for my local use
    118 case. You will find many local constructs, to show you the possibilities of
    119 the plumber(1) architecture. To keep plumber as flexible as possible I did not
    120 introduce any intermediate description language or yet another scripting
    121 language. It is all calling scripts and calling scripts all the way down.
    122 
    123 For adding some opener, just create the script (I name them \*opener.) and
    124 reference them from plumber(1).
    125 
    126 Many helper applications are not included. You will find them in further
    127 published applications in my git repository. If you feel interest in some,
    128 contact me and I am open to give away the source code.
    129 
    130 ## How does it work?
    131 
    132 There is a hierarchy of URIs. First of all the scheme is parsed, like
    133 »http://« or »portage:«, then some opener is called. If the URI or string
    134 given to the plumber is a local file, »see« (part of mailcap) is run, which
    135 will do the mime parsing and is configured through your $HOME/.mailcap. See
    136 the appropriate manpages, how to configure this.
    137 
    138 When the plumber calls a helper, there are simple and complex openers. For a
    139 really complex one, see the webopener(1). It allows for now just one fun
    140 parsing for the headers, just for the demonstration of what's possible. You
    141 could do all kind of cache checking or header parsing before calling some
    142 application.
    143 
    144 If you see my example plumber(1) script, you notice that you need to edit the
    145 python file. That's way easier than having to parse a file on every startup.
    146 Making this a configuration file would be easy but out of scope. In the end
    147 you write your own handlers, which includes coding. Without coding plumber(1)
    148 will not help you much.
    149 
    150 Back to the web example. As you see, images are handled directly, instead of
    151 going through a huge bloated webbrowser. Text files are given to a text web
    152 browser and so stop you from seeing all the web bloat and time wasting
    153 advertisements.
