+=head1 NAME
+
+coords - weechat script to map screen coordinates (weechat edition)
+
+=head1 SYNOPSIS
+
+first, copy the file to your
+F<.weechat/perl> directory. Then you can type
+
+  /script load coords.pl
+
+in weechat to load the script. Use
+
+  /coords
+
+to open the coords screen, or conveniently
+
+  /key bind meta-/ /coords /
+
+to open it with the Alt+/ keybinding.
+
+=head1 DESCRIPTION
+
+coords will hilight links, allow text selection and tries to send the
+selection to xterm
+
+=head1 SETUP
+
+if you would like urls to be copied into the selection clipboard, add
+
+  xterm*disallowedWindowOps:20,21,SetXprop
+
+to your F<.Xresources> file for B<xterm>.
+
+For B<rxvt-unicode>, get the F<osc-xterm-clipboard> script from
+L<http://anti.teamidiot.de/static/nei/*/Code/urxvt/>, install it to
+your F<perl-lib> directory and add it to your F<.Xresources> like such:
+
+  URxvt.perl-ext-common: default,osc-xterm-clipboard
+
+=head1 USAGE
+
+to open the url overlay on a window, type C</coords> or use the
+keybinding you created as explained in the L</SYNOPSIS>.
+
+=head2 Selection Mode
+
+by default, the copy window will be in selection mode. you can move
+the text cursor with the arrow keys and open a selection with the
+Space key. The selection content will be transfered into clipboard.
+
+=head2 URL Mode
+
+to switch between selection mode and URL mode, use the C</> key or
+type the command C</coords /> to directly start in URL mode.
+
+inside the overlay, you can use Arrow-Up and Arrow-Down keys to select
+URLs. This script will try to copy them into your selection clipboard
+(see L</SETUP>) so you should be able to open the selected link by
+clicking the middle mouse button in your browser.
+
+once you click or hit enter, an url open signal will be sent to
+WeeChat. Use an appropriate script such as F<urlopener.pl> from
+L<http://anti.teamidiot.de/static/nei/*/Code/WeeChat/> if you would
+like to associate this with some application (web browser etc.)
+
+to leave the overlay, hit the C<q> key.
+
+for mouse support, this script will listen to mouse input
+signals. Another script is needed to supply these signals, such as
+F<mouse.pl> which can be found in the same place as F<urlopener.pl>
+and this script.
+
+=head1 CAVEATS
+
+=over
+
+=item *
+
+WeeChat does not allow for visual feedback during mouse operation
+unless you patch it and use the F<mouse.pl> or F<mouse_var.pl> script
+instead.
+
+=item *
+
+double-click word select does not work in an unpatched WeeChat for the
+same reason -- unless you set a very high close_on_release timeout (with
+the added inconvenience).
+
+=item *
+
+unfortunately, WeeChat scrolls back a buffer to the end when you
+switch to any other buffer, including the copy window
+overlay. F<coords.pl> will work together with the F<keepscroll.pl>
+script to try and remedy this a little bit, but the perfect scrolling
+position cannot be restored due to internal limitations. (no longer
+the case in recent versions of WeeChat.)
+
+=item *
+
+whether other terminal emulators support selection storage, depends on
+how well they emulate B<xterm>. Set C<xterm_compatible> to your
+I<$TERM> if you think it does.
+
+=item *
+
+B<xterm> will not allow selection storage unless you enable it in the
+Xresources as described in L</SETUP>
+
+=item *
+
+B<rxvt-unicode> will need a script to handle the selection operating
+system control. querying the selection is only supported if the
+selection is rxvt-unicodeE<apos>s (not needed for this script)
+
+=item *
+
+GNU B<screen> will not allow to pass through the operating system
+control needed for selection storage to the underlying term, try
+B<tmux> instead (L<http://tmux.sourceforge.net/>)
+
+=item *
+
+it would be possible to provide a remote clipboard, but that will
+require a clipboard server. Also see B<xsel>, B<xclip>, command mode
+
+=back
+

+
+=over
+

+set the text input cursor on click in the input bar
+
+=back
+
+=head1 BUGS
+
+=over
+
+=item *
+
+my local B<xterm> exhibits a bug where the selection is only copied if
+you I<click> into the xterm window first. still trying to figure this
+one out...
+

+
+=head1 SETTINGS
+
+the settings are usually found in the
+
+  plugins.var.perl.coords
+
+namespace, that is, type
+
+  /set plugins.var.perl.coords.*
+
+to see them and
+
+  /set plugins.var.perl.coords.SETTINGNAME VALUE
+
+to change a setting C<SETTINGNAME> to a new value C<VALUE>. Finally,
+
+  /unset plugins.var.perl.coords.SETTINGNAME
+
+will reset a setting to its default value.
+
+the following settings are available:
+
+=head2 url_regex
+
+a regular expression to identify URLs in the text. See L<perlre> for
+more information about Perl regular expressions.
+
+=head2 url_braces
+
+parenthesis-like characters which nest and should be excluded when
+found around an URL. make sure the variable setting nests properly
+when modifying this.
+
+=head2 url_non_endings
+
+this is matched against the end of a link and removed
+
+=head2 hyper_nicks
+
+make nicks to hyperlinks for menu/pm
+
+=head2 hyper_channels
+
+make channels to hyperlinks for join
+
+=head2 hyper_show
+
+set to types of hyperlinks that are shown by default
+
+=head2 use_nick_menu
+
+use nick menu when opening nick hyperlink (see I<hyper_nicks>,
+requires menu.pl script). otherwise open private message. this setting
+only applies to text mode selection, for mouse see
+I<mouse.nick_2nd_click>
+
+=head2 color.url_highlight
+
+the weechat color and/or attribute to be used for highlighting URLs in
+the copy window. seperate multiple attributes with C<.>
+
+=head2 color.url_highlight_active
+
+the same as I<color.url_highlight> except for the currently (using
+arrow keys) selected link.
+
+=head2 color.selection_cursor
+
+the weechat color and/or attribute to be used for the text cursor.
+
+=head2 color.selection
+
+the color of the currently selected text in selection mode
+
+=head2 copybuf_short_name
+
+short_name to use for coords buffer. it is set to the copy sign by
+default to not disturb buffers bar width, set to the empty string to
+have window position and size shown
+
+=head2 mouse.copy_on_click
+
+set to on if it should be possible to directly click on URLs and
+select text, set to off if mouse should only work in open coords
+buffer
+
+=head2 mouse.close_on_release
+
+set to on or a delay (in ms) to autoclose coords buffer opened by
+I<copy_on_click> on button release, set to off if the coords buffer
+should stay open after click
+
+=head2 mouse.click_select_pane
+
+set to on to use the mouse to select windows
+
+=head2 mouse.click_through_pane
+
+set to on if I<copy_on_click> should work on inactive windows (works
+only if I<click_select_pane> is set too). set to off if window needs
+to be active
+
+=head2 mouse.url_open_2nd_click
+
+if this is set, URLs are only opened when clicked twice (in the same
+incarnation of a coords buffer) instead of on first click. it can be set to
+a delay (in ms) that will be added to the I<close_on_release> delay if
+the script is waiting for a second click on the URL to happen
+
+=head2 mouse.handle_scroll
+
+set to on if coords should handle scrolling inside windows. the script
+will try to guess non-chat areas to be nicklist, top to be title and
+bottom to be status and scroll the respective bars if the cursor is in
+that area. set to off if scrolling should be handled by the default
+F<mouse.pl> script or another mouse scrolling script
+
+=head2 mouse.scroll_inactive_pane
+
+set to on if inactive windows should be scrolled instead of active
+window if the mouse cursor is over it (requires I<handle_scroll> to be
+enabled)
+
+=head2 clipboard_command
+
+if you set this, an external program may be executed to store the
+selection or URL. begin with C<|> to pipe into program or use
+parameters C<%s> for text, C<%q> for quoted text or C<%x> for quoted
+escape sequence.
+
+=head2 copywin_custom_keys
+
+You can define custom key bindings to use inside the copywin here. syntax is:
+command-letter:weechat-keycode. available commands: -+>< (up/down/left/right)
+fbae (forward word/backward word/beginning/end) !@ (open/start selection)
+/UNCunc (toggle highlights/urls/nicks/channels) q (close window)
+
+=head1 FUNCTION DESCRIPTION

+
