andyk / ht Goto Github PK

This looks like it really wants to integrate https://github.com/asciinema/asciinema to record and replay interactions.

It might also be useful to check out https://github.com/oilshell/oil/wiki/Headless-Mode

raw terminal gave a lot of garbed characters. I wish this ht may make ssh interactive session cleaner.

ht ssh username@remote-host
launching command "ssh username@remote-host" in terminal of size 120x40

it waited there forever, actually in normal terminal, it prompts to as ask password, how do I get prompt and feed my input?

Hi,

I am curious whether you have some tools_example.py to share, in order to be able to function call some sample commands or interact via new Mistral7b v0.3 (which is the first open weights model to support funccaling)?

Cheers

ht's API is an RPC-style newline-delimited JSON sent over stdin/stdout. This reminds me strongly of varlink, an IPC standard used by systemd and podman (the docker alternative). The biggest difference is that varlink uses null-byte-delimited JSON rather than newline-delimited JSON, and usually uses Unix sockets instead of stdin/stdout (so that many clients can connect at once).

What could be gained?

• Instead of maintaining a list of supported methods in project README, with "this method returns XYZ" / "this method doesn't return", you could maintain a varlink IDL file
• Streaming support, so that clients don't have to poll getView
• Error messages by setting the error field in reply JSON
• varlink CLI and systemd-varlinkctl CLI may make scripting and debugging easier
• Autogenerated correct clients in many languages
• Introspection - every varlink server has to reply to GetInfo and GetInterfaceDescription messages. This makes it easy for clients to see if a server version is new enough to support some new methods.

Does ht interpret ANSI escape codes? There are many protocols that I think ht could interpret and transform into JSON messages. Or if not, then explicitly forward them further over getView API (or a new getUnsanitizedView / getRawView).

Some protocols that are somewhat important for modern terminal experience:

• colors,
• clickable links,
• mouse integration,
• clipboard copy/paste,
• setting title and cwd

One of the most frequent question in https://news.ycombinator.com/item?id=40552257 was "but what would i need it for?". There were some good arguments and ideas there, I think it would be nice to put them in the readme

Is there a way to, say, wait for text to appear on the screen without taking screenshots and waiting 100 milliseconds?

Does ht support sending a signal to current (foreground) process? How to send SIGINT or SIGKILL?

My Unix knowledge is rusty, but I think ht doesn't need to know what the foreground process is. If you send a signal to pty, AFAIK the kernel will somehow forward it to the foreground process in the process group.
