49loaded automatically when used. 49which can be bound to a key and invoked by the user. An extension can
50define the resources it support using so called META comments,
51described below. Similarly to builtin resources, extension resources
52can also be specified on the command line as long options (with C<.>
53replaced by C<->), in which case the corresponding extension is loaded
54automatically. For this to work the extension B<must> define META
55comments for its resources.

117=head2 META comments
118
119Rxvt-unicode recognizes special meta comments in extensions that define
120different types of metadata. These comments are scanned whenever a
121terminal is created and are typically used to autoload extensions when
122their resources or command line parameters are used.
123
124Currently, it recognises these comments below. Individual components are
125separated by colons (C<:>), and should not contain colons themselves -
126there is also currently no escaping mechanism provided for this.
127
128=over
129
130=item #:META:RESOURCE:name:type:desc
131
132The RESOURCE comment defines a resource used by the extension, where
133C<name> is the resource name, C<type> is the resource type, C<boolean>
134or C<string>, and C<desc> is the resource description.
135
136The extension will be autoloaded when this resource is specified or used
137as a command line parameter.
138
139Example: matcher provides the C<matcher.launcher> resource by having this
140comment:
141
142 #:META:RESOURCE:%.launcher:string:default launcher command
143
144Example: load this extension when the C<-tr> command line option or
145resource name is used.
146
147 #:META:RESOURCE:tr:boolean:set root pixmap as background
148
149=item #:META:OSC:number:desc
150
151The OSC comment specifies an OSC sequence, where C<number> is the
152numerical OSC code and C<desc> is a short description that is currently
153unused.
154
155This will cause the extension to be autoloaded when the OSC sequence is
156used for the first time.
157
158Note that autoloading carries some extra responsibilities with it:
159although the terminal cannot really protect itself against malicious
160sources of command sequences, therefore relying on the programs running
161I<inside> to sanitize data that they output, it is very common for
162programs to emit command sequences from untrusted sources.
163
164While this means that extensions should, as a defense-in-depth mechanism,
165always consider whether OSC sequences are safe, autoloading automatically
166exposes any autoloaded extension in all terminal windows, so extra care
167should be taken.
168
169Example: the background extension registers OSC C<20> like this:
170
171 #:META:OSC:20:change/query background image
172
173=item #:META:OSC_PERL:prefix:desc
174
175The same as the OSC comment, but for the Perl OSC sequence (C<777>). The
176C<prefix> should be unique among extensions, of course, which is most
177easily arranged by using the extension name, although this is not
178required.
179
180Example: the overlay-osc extension registers its Perl OSC like this:
181
182 #:META:OSC_PERL:overlay:man overlay-osc

204Called when an extension package is attached to a running terminal
205instance. Must return true in all cases, and runs with the same
206limitations as C<on_init>.
207
208Unlike C<on_init> or C<on_start>, this is called when the extension is
209attached to a terminal, regardless of whether the extension is loaded
210before or after the terminal is started. Extensions that need to do
211something before they work can do it in this callback, as opposed to e.g.
212C<on_init>, which might not be called.
