Text output may contain hyperlinks. These hyperlinks are encoded through
an escape sequence, specified at
Hyperlinks in terminal emulators. Currently (as of 2019), they are
displayed only in
gnome-terminal version 3.26 or above. More
terminal emulators will support hyperlinks in the future. Terminal
emulators which don’t support hyperlinks ignore it, except for a few
terminal emulators, for which users may need to disable the hyperlinks
(see The NO_TERM_HYPERLINKS variable) if the heuristic built into
libtextstyle does not already disable them.
To emit a hyperlink, use code like this:
styled_ostream_t stream = ... ... /* Start a hyperlink. */ styled_ostream_set_hyperlink (stream, url, NULL); ... /* Emit the anchor text. This can be styled text. */ ostream_write_str (stream, "Click here!"); ... /* End the current hyperlink. */ styled_ostream_set_hyperlink (stream, NULL, NULL);
The anchor text can be styled. But the hyperlinks themselves cannot be styled; they behave as implemented by the terminal emulator.
