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.

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>

The :pipe command is used to pipe the selection(s) to a shell

commands to modify text in helix.

On a linux system with jq installed, move to the line starting

with a { , select the whole line content, and enter

with a { , select the whole line content pressing x, and enter

:pipe jq

* 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
