The :pipe-to command is used to pipe the current selection(s)
as argument(s) to a shell command. This can be useful e.g.
for scripting. If you have a Linux like system with spd-say
text-to-speech installed, move to the line starting by -->,
select the text on the line, and enter
:pipe-to spd-say
to a shell command, as would be done by
echo "<selection contents>" | <command>
This can be useful e.g. for scripting. If you have a Linux like
system with spd-say text-to-speech installed, move to the line
starting by -->, select the text on the line, and enter
:pipe-to spd-say -e

* Shell commands can be run from helix and their output inserted
(resp. appended) using :insert-output (resp :append-output),
also aliased as Alt-! (resp !)
* Selections can be piped to a shell command and their output
can overwrite the commmand (resp. be discarded) using :pipe
(resp. :pipe-to), also aliased as | (resp. Alt-| ). Remember
that this is piping the selection(s), not providing as
arguments.
