-# This script replaces the default prompt status-bar item with one capable
-# of displaying additional information, under either user control or via
-# scripts.
-#
-# INSTALL:
-#
-# Place script in ~/.irssi/scripts/ and potentially symlink into autorun/
-# to ensure it starts at irssi startup.
-#
-# If not using autorun, manually load the script via:
-#
-# /script load uberprompt.pl
-#
-# If you have a custom prompt format, you may need to copy it to the
-# uberprompt_format setting. See below for details.
-#
-# USAGE:
-#
-# Although the script is designed primarily for other scripts to set
-# status information into the prompt, the following commands are available:
-#
-# TODO: Document positional settings.
-#
-# /prompt set   - sets the prompt to the given argument. $p in the argument will
-#                 be replaced by the original prompt content.
-# /prompt clear - clears the additional data provided to the prompt.
-# /prompt on    - enables the uberprompt (things may get confused if this is used
-#                 whilst the prompt is already enabled)
-# /prompt off   - restore the original irssi prompt and prompt_empty statusbars.
-#                 unloading the script has the same effect.
-#
-# Additionally, the format for the prompt can be set via:
-#
-# UBERPROMPT FORMAT:
-#
-# /set uberprompt_format <format>
-#
-# The default is [$*], which is the same as the default provided in default.theme.
-# Changing this setting will update the prompt immediately, unlike editing your theme.
-#
-# An additional variable available within this format is '$uber', which expands to
-# the content of prompt data provided with the UP_INNER placement argument. For all
-# other placement arguments, it will expand to the empty string ''.
-#
-# NOTE: this setting completely overrides the prompt="..." line in your .theme
-#       file, and may cause unexpected behaviour if your theme wishes to set a
-#       different form of prompt. It can be simply copied from the theme file into
-#       the above setting.
-#
-# Usage from other Scripts: signal 'change prompt' => 'string' => position
-#
-# eg:
-#
-# signal_emit 'change prompt' 'some_string', UberPrompt::UP_INNER;
-#
-# will set the prompt to include that content, by default '[$* some_string]'
-#
-# The possible position arguments are the following strings:
-#
-# UP_PRE   - place the provided string before the prompt -- $string$prompt
-# UP_INNER - place the provided string inside the prompt -- {prompt $* $string}
-# UP_POST  - place the provided string after the prompt  -- $prompt$string
-# UP_ONLY  - replace the prompt with the provided string -- $string
-#
-# All strings may use the special variable '$prompt' to include the prompt
-# verbatim at that position in the string.  It is probably only useful for
-# the UP_ONLY mode however. '$prompt_nt' will include the prompt, minus any
-# trailing whitespace.
-#
-# NOTIFICATIONS:
-#
-# You can also be notified when the prompt changes in response to the previous
-# signal or manual commands via:
-#
-# signal_add 'prompt changed', sub { my ($text, $len) = @_; ... do something ... };
-#
-# Bugs:
-#
-# * Resizing the terminal rapidly whilst using this script in debug mode
-#    may cause irssi to crash. See bug report at
-#    http://bugs.irssi.org/index.php?do=details&task_id=772 for details.
-#
-# TODO:
-#
-# * report failure (somehow) to clients if hte prompt is disabled.
-# * fix issue at autorun startup with sbar item doesn't exist.

+=head1 NAME
+
+uberprompt.pl
+
+=head1 DESCRIPTION
+
+This script replaces the default prompt status-bar item with one capable of
+displaying additional information, under either user control or via scripts.
+
+=head1 INSTALLATION
+
+Copy into your F<~/.irssi/scripts/> directory and load with
+C</SCRIPT LOAD F<filename>>.
+
+It is recommended that you make it autoload in one of the
+L<usual ways|https://github.com/shabble/irssi-docs/wiki/Guide#Autorunning_Scripts>.
+
+=head1 SETUP
+
+If you have a custom prompt format, you may need to copy it to the
+uberprompt_format setting. See below for details.
+
+=head1 USAGE
+
+Although the script is designed primarily for other scripts to set
+status information into the prompt, the following commands are available:
+
+=over 4
+
+=item * C</prompt set [-inner|-pre|-post|only] E<lt>msgE<gt>>
+
+Sets the prompt to the given argument. Any use of C<$p> in the argument will
+be replaced by the original prompt content.
+
+A parameter corresponding to the C<UP_*> constants listed below is required, in
+the format C</prompt set -inner Hello!>
+
+=item * C</prompt clear>
+
+Clears the additional data provided to the prompt.
+
+=item * C</prompt on>
+
+Eenables the uberprompt (things may get confused if this is used
+whilst the prompt is already enabled)
+
+=item * C</prompt off>
+
+Restore the original irssi prompt and prompt_empty statusbars.  unloading the
+script has the same effect.
+
+=item * C</help prompt>
+
+show help for uberprompt commands
+
+=back
+
+=head1 SETTINGS
+
+=head2 UBERPROMPT FORMAT
+
+C</set uberprompt_format E<lt>formatE<gt>>
+
+The default is C<[$*$uber]>, which is the same as the default provided in
+F<default.theme>.
+
+Changing this setting will update the prompt immediately, unlike editing your theme.
+
+An additional variable available within this format is C<$uber>, which expands to
+the content of prompt data provided with the C<UP_INNER> or C</prompt set -inner>
+placement argument.
+
+For all other placement arguments, it will expand to the empty string.
+
+B<Note:> This setting completely overrides the C<prompt="...";> line in your
+.theme file, and may cause unexpected behaviour if your theme wishes to set a
+different form of prompt. It can be simply copied from the theme file into the
+above setting.
+
+=head2 OTHER SETTINGS
+
+=over 4
+
+=item * C<uberprompt_autostart>
+
+Boolean value, which determines if uberprompt should enable itself automatically
+upon loading.  If Off, it must be enabled manually with C</prompt on>.  Defaults to On.
+
+=item * C<uberprompt_debug>
+
+Boolean value, which determines if uberprompt should print debugging information.
+Defaults to Off, and should probably be left that way unless requested for bug-tracing
+purposes.
+
+=item * C<uberprompt_format>
+
+String value containing the format-string which uberprompt uses to display the
+prompt. Defaults to "C<[$*$uber] >", where C<$*> is the content the prompt would
+normally display, and C<$uber> is a placeholder variable for dynamic content, as
+described in the section above.
+
+=item * C<uberprompt_load_hook>
+
+String value which can contain one or more commands to be run whenever the uberprompt
+is enabled, either via autostart, or C</prompt on>. Defaults to the empty string, in
+which case no commands are run.  Some examples include:
+
+C</set uberprompt_load_hook /echo prompt enabled> or
+
+C</^sbar prompt add -after input vim_mode> for those using vim_mode.pl who want
+the command status indicator on the prompt line.
+
+=item * C<uberprompt_unload_hook>
+
+String value, defaulting to the empty string, which can contain commands which
+are executed when the uberprompt is disabled, either by unloading the script,
+or by the command C</prompt off>.
+
+=item * C<uberprompt_use_replaces>
+
+Boolean value, defaults to Off. If enabled, the format string for the prompt
+will be subject to the I<replaces> section of the theme.  The most obvious
+effect of this is that bracket characters C<[ ]> are displayed in a different
+colour, typically quite dark.
+
+=back
+
+B<Note:> For both C<uberprompt_*_hook> settings above, multiple commands can
+be chained together in the form C</eval /^cmd1 ; /^cmd2>. The C<^> prevents
+any output from the commands (such as error messages) being displayed.
+
+=head2 SCRIPTING USAGE
+
+The primary purpose of uberprompt is to be used by other scripts to
+display information in a way that is not possible by printing to the active
+window or using statusbar items.
+
+The content of the prompt can be set from other scripts via the C<"change prompt">
+signal.
+
+For Example:
+
+    signal_emit 'change prompt' 'some_string', UberPrompt::UP_INNER;
+
+will set the prompt to include that content, by default 'C<[$* some_string]>'
+
+The possible position arguments are the following strings:
+
+=over 4
+
+=item * C<UP_PRE>   - place the provided string before the prompt - C<$string$prompt>
+
+=item * C<UP_INNER> - place the provided string inside the prompt - C<{prompt $* $string}>
+
+=item * C<UP_POST>  - place the provided string after the prompt  - C<$prompt$string>
+
+=item * C<UP_ONLY>  - replace the prompt with the provided string - C<$string>
+
+=back
+
+All strings may use the special variable 'C<$prompt>' to include the prompt
+verbatim at that position in the string.  It is probably only useful for
+the C<UP_ONLY> mode however. '$C<prompt_nt>' will include the prompt, minus any
+trailing whitespace.
+
+=head2 CHANGE NOTIFICATIONS
+
+You can also be notified when the prompt changes in response to the previous
+signal or manual C</prompt> commands via:
+
+    signal_add 'prompt changed', sub { my ($text, $len) = @_; ... do something ... };
+
+This callback will occur whenever the contents of the prompt is changed.
+
+
+=head2 NOTES FOR SCRIPT WRITERS:
+
+The following code snippet can be used within your own script as a preamble
+to ensure that uberprompt is loaded before your script to avoid
+any issues with loading order.  It first checks if uberprompt is loaded, and
+if not, attempts to load it.  If the load fails, the script will die
+with an error message, otherwise it will call your app_init() function.
+
+I<---- start of snippet ---->
+
+    my $DEBUG_ENABLED = 0;
+    sub DEBUG () { $DEBUG_ENABLED }
+
+    # check we have uberprompt loaded.
+
+    sub script_is_loaded {
+       return exists($Irssi::Script::{$_[0] . '::'});
+    }
+
+    if (not script_is_loaded('uberprompt')) {
+
+        print "This script requires 'uberprompt.pl' in order to work. "
+          . "Attempting to load it now...";
+
+        Irssi::signal_add('script error', 'load_uberprompt_failed');
+        Irssi::command("script load uberprompt.pl");
+
+        unless(script_is_loaded('uberprompt')) {
+            load_uberprompt_failed("File does not exist");
+        }
+        app_init();
+    } else {
+        app_init();
+    }
+
+    sub load_uberprompt_failed {
+        Irssi::signal_remove('script error', 'load_prompt_failed');
+
+        print "Script could not be loaded. Script cannot continue. "
+          . "Check you have uberprompt.pl installed in your path and "
+            .  "try again.";
+
+        die "Script Load Failed: " . join(" ", @_);
