|
|
139 | Example: matcher provides the C<matcher.launcher> resource by having this |
|
|
140 | comment: |
|
|
141 | |
|
|
142 | #:META:RESOURCE:%.launcher:string:default launcher command |
|
|
143 | |
|
|
144 | Example: load this extension when the C<-tr> command line option or |
|
|
145 | resource name is used. |
|
|
146 | |
|
|
147 | #:META:RESOURCE:tr:boolean:set root pixmap as background |
|
|
148 | |
|
|
149 | =item #:META:OSC:number:desc |
|
|
150 | |
|
|
151 | The OSC comment specifies an OSC sequence, where C<number> is the |
|
|
152 | numerical OSC code and C<desc> is a short description that is currently |
|
|
153 | unused. |
|
|
154 | |
|
|
155 | This will cause the extension to be autoloaded when the OSC sequence is |
|
|
156 | used for the first time. |
|
|
157 | |
|
|
158 | Note that autoloading carries some extra responsibilities with it: |
|
|
159 | although the terminal cannot really protect itself against malicious |
|
|
160 | sources of command sequences, therefore relying on the programs running |
|
|
161 | I<inside> to sanitize data that they output, it is very common for |
|
|
162 | programs to emit command sequences from untrusted sources. |
|
|
163 | |
|
|
164 | While this means that extensions should, as a defense-in-depth mechanism, |
|
|
165 | always consider whether OSC sequences are safe, autoloading automatically |
|
|
166 | exposes any autoloaded extension in all terminal windows, so extra care |
|
|
167 | should be taken. |
|
|
168 | |
|
|
169 | Example: 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 | |
|
|
175 | The same as the OSC comment, but for the Perl OSC sequence (C<777>). The |
|
|
176 | C<prefix> should be unique among extensions, of course, which is most |
|
|
177 | easily arranged by using the extension name, although this is not |
|
|
178 | required. |
|
|
179 | |
|
|
180 | Example: the overlay-osc extension registers its Perl OSC like this: |
|
|
181 | |
|
|
182 | #:META:OSC_PERL:overlay:man overlay-osc |
