stdin in r2 command, new internal pipe syntax proposal

[trufae]

Opening a discussion for #14004 and closing the ticket.

The idea is to be able to write something like this:

pz~[0] || axt

the idea is that we want to be able to use pipes ini r2 commands, but r2 commands dont get anything from stdin, so instead of using babckticks and @@ iterators we need a way to express it in a pipe-form, similiar to how xargs work in unix

In that case that would work the same way as this:

axt @@=`pz~[0]`

But as long as || acts as stdin we may probably want to handle stdin pipes in more commands like w for writing strings passed as stdin, those expressions could be groupped inside iterators @@.

izqq || w+

Maybe this ticket should be moved into the discussions tab

Actually a note about 'complicated' syntax is understandable.
What would that make easier?

Why not rely on the external OS pipe? Like powershell or bash?

Because that will require creating new processes which is something not portable. You cant do this on ios or wasm for example.
