# syndicate-pty-driver
|
|
|
|
[protocol]: protocols/schemas/pty.prs
|
|
|
|
A PTY (pseudoterminal) driver for [Syndicate](https://syndicate-lang.org), plus [protocol
|
|
schema][protocol] for PTY interaction via Syndicate.
|
|
|
|
Expects to be started from
|
|
[syndicate-server](https://git.syndicate-lang.org/syndicate-lang/syndicate-rs/), perhaps via
|
|
configuration like this:
|
|
|
|
```preserves
|
|
<require-service <daemon pty>>
|
|
<daemon pty { protocol: application/syndicate, argv: "syndicate-pty-driver" }>
|
|
```
|
|
|
|
It publishes a service object which then speaks the [PTY protocol][protocol]. You can start a
|
|
program running in a fresh PTY like this:
|
|
|
|
```preserves
|
|
# As soon as the PTY driver publishes its service object, $cap, ...
|
|
? <service-object <daemon pty> ?cap> [
|
|
# ... assert interest in existence of a session with id 1 running `bash -i`.
|
|
$cap += <pty-session 1 [bash -i]>
|
|
]
|
|
```
|
|
|
|
Then, expect `<pty-output ...>` messages and send `<pty-input ...>` messages to interact with
|
|
the subprocess.
|
|
|
|
See the [protocol definition][protocol] for more about interacting with PTYs over Syndicate.
