1 | # ht - headless terminal
2 |
3 | `ht` (short for *headless terminal*) is a command line program that wraps an arbitrary other binary (e.g. `bash`, `vim`, etc.) with a VT100 style terminal interface--i.e. a pseudoterminal client (PTY) plus terminal server--and allows easy programmatic access to the input and output of that terminal (via JSON over STDIN/STDOUT). `ht` is built in rust and works on MacOS and Linux.
4 |
5 | 
6 |
7 |
8 | ## Use Cases & Motivation
9 |
10 | `ht` is useful for programmatically interacting with terminals, which is important for programs that depend heavily on the Terminal as UI. It is useful for testing and for getting AI agents to interact with terminals the way humans do.
11 |
12 | The original motiving use case was making terminals easy for LLMs to use. I was trying to use LLM agents for coding, and needed something like a **headless browser** but for terminals.
13 |
14 | Terminals are one of the oldest and most prolific UI frameworks in all of computing. And they are stateful so, for example, when you use an editor in your terminal, the terminal has to manage state about the cursor location. Without ht, an agent struggles to manage this state directly; with ht, an agent can just observe the terminal like a human does.
15 |
16 | ## Installing
17 | Download and use [the latest binary](https://github.com/andyk/ht/releases/latest) for your architecture.
18 |
19 | ## Building
20 |
21 | Building from source requires the [Rust](https://www.rust-lang.org/) compiler
22 | (1.74 or later), and the [Cargo package
23 | manager](https://doc.rust-lang.org/cargo/). If they are not available via your
24 | system package manager then use [rustup](https://rustup.rs/).
25 |
26 | To download the source code, build the binary, and install it in
27 | `$HOME/.cargo/bin` run:
28 |
29 | ```sh
30 | cargo install --git https://github.com/andyk/ht
31 | ```
32 |
33 | Then, ensure `$HOME/.cargo/bin` is in your shell's `$PATH`.
34 |
35 | Alternatively, you can manually download the source code and build the binary
36 | with:
37 |
38 | ```sh
39 | git clone https://github.com/andyk/ht
40 | cd ht
41 | cargo build --release
42 | ```
43 |
44 | This produces the binary in _release mode_ (`--release`) at
45 | `target/release/ht`. There are no other build artifacts so you can just
46 | copy the binary to a directory in your `$PATH`.
47 |
48 | ## Usage
49 |
50 | Run `ht` to start interactive bash shell running in a PTY (pseudo-terminal).
51 |
52 | To launch a different program (a different shell, another program) run `ht
53 | `. For example:
54 |
55 | - `ht fish` - starts fish shell
56 | - `ht nano` - starts nano editor
57 | - `ht nano /etc/fstab` - starts nano editor with /etc/fstab opened
58 |
59 | Another way to run a specific program, e.g. `nano`, is to launch `ht` without a
60 | command, i.e. use bash by default, and start nano from bash by sending `nano\r`
61 | ("nano" followed by "return" control character) to the process input. See [input
62 | command](#input) below.
63 |
64 | Default size of the virtual terminal window is 120x40 (cols by rows), which can
65 | be changed with `--size` argument. For example: `ht --size 80x24`. The window
66 | size can also be dynamically changed - see [resize command](#resize) below.
67 |
68 | Run `ht -h` or `ht --help` to see all available options.
69 |
70 | ## Live terminal preview
71 |
72 | ht comes with a built-in HTTP server which provides a handy live terminal preview page.
73 |
74 | To enable it, start ht with `-l` / `--listen` option. This will print the URL of
75 | the live preview.
76 |
77 | By default it listens on `127.0.0.1` and a system assigned, dynamic port. If you
78 | need it to bind to another interface, or a specific port, pass the address to
79 | the `-l` option, e.g. `-l 0.0.0.0:9999`.
80 |
81 | ## API
82 |
83 | ht provides 2 types of API: STDIO and WebSocket.
84 |
85 | The STDIO API allows control and introspection of the terminal using STDIN,
86 | STDOUT and STDERR.
87 |
88 | WebSocket API provides several endpoints for getting terminal updates in
89 | real-time. Websocket API is _not_ enabled by default, and requires starting the
90 | built-in HTTP server with `-l` / `--listen` option.
91 |
92 | ### STDIO API

94 | ht uses simple JSON-based protocol for sending commands to its STDIN. Each
95 | command must be sent on a separate line and be a JSON object having `"type"`
96 | field set to one of the supported commands (below).
97 |
98 | Some of the commands trigger [events](#events). ht may also internally trigger
99 | various events on its own. To subscribe to desired events use `--subscribe
100 | [,,...]` option when starting ht. This will print the
101 | events as they occur to ht's STDOUT, as JSON-encoded objects. For example, to
102 | subscribe to view snapshots (triggered by sending `takeSnapshot` command) use
103 | `--subscribe snapshot` option. See [events](#events) below for a list of
104 | available event types and their payloads.
105 |
106 | Diagnostic messages (notices, errors) are printed to STDERR.
107 |
108 | #### sendKeys
109 |
110 | `sendKeys` command allows sending keys to a process running in the virtual
111 | terminal as if the keys were pressed on a keyboard.
112 |
113 | ```json
114 | { "type": "sendKeys", "keys": ["nano", "Enter"] }
115 | { "type": "sendKeys", "keys": ["hello", "Enter", "world"] }
116 | { "type": "sendKeys", "keys": ["^x", "n"] }
117 | ```
118 |
119 | Each element of the `keys` array can be either a key name or an arbitrary text.
120 | If a key is not matched by any supported key name then the text is sent to the
121 | process as is, i.e. like when using the `input` command.
122 |
123 | The key and modifier specifications were inspired by
124 | [tmux](https://github.com/tmux/tmux/wiki/Modifier-Keys).
125 |
126 | The following key specifications are currently supported:
127 |
128 | - `Enter`
129 | - `Space`
130 | - `Escape` or `^[` or `C-[`
131 | - `Tab`
132 | - `Left` - left arrow key
133 | - `Right` - right arrow key
134 | - `Up` - up arrow key
135 | - `Down` - down arrow key
136 | - `Home`
137 | - `End`
138 | - `PageUp`
139 | - `PageDown`
140 | - `F1` to `F12`
141 |
142 | Modifier keys are supported by prepending a key with one of the prefixes:
143 |
144 | - `^` - control - e.g. `^c` means Ctrl + C
145 | - `C-` - control - e.g. `C-c` means Ctrl + C
146 | - `S-` - shift - e.g. `S-F6` means Shift + F6
147 | - `A-` - alt/option - e.g. `A-Home` means Alt + Home
148 |
149 | Modifiers can be combined (for arrow keys only at the moment), so combinations
150 | such as `S-A-Up` or `C-S-Left` are possible.
151 |
152 | `C-` control modifier notation can be used with ASCII letters (both lower and
153 | upper case are supported) and most special key names. The caret control notation
154 | (`^`) may only be used with ASCII letters, not with special keys.
155 |
156 | Shift modifier can be used with special key names only, such as `Left`, `PageUp`
157 | etc. For text characters, instead of specifying e.g. `S-a` just use upper case
158 | `A`.
159 |
160 | Alt modifier can be used with any Unicode character and most special key names.
161 |
162 | This command doesn't trigger any event.
163 |
164 | #### input
165 |
166 | `input` command allows sending arbitrary raw input to a process running in the
167 | virtual terminal.
168 |
169 | ```json
170 | { "type": "input", "payload": "ls\r" }
171 | ```
172 |
173 | In most cases it's easier and recommended to use the `sendKeys` command instead.
174 |
175 | Use the `input` command if you don't want any special input processing, i.e. no
176 | mapping of key names to their respective control sequences.
177 |
178 | For example, to send Ctrl-C shortcut you must use `"\u0003"` (0x03) as the
179 | payload:
180 |
181 | ```json
182 | { "type": "input", "payload": "\u0003" }
183 | ```
184 |
185 | This command doesn't trigger any event.
186 |
187 | #### takeSnapshot
188 |
189 | `takeSnapshot` command allows taking a textual snapshot of the the terminal view.
190 |
191 | ```json
192 | { "type": "takeSnapshot" }
193 | ```
194 |
195 | This command triggers `snapshot` event.
196 |
197 | #### resize
198 |
199 | `resize` command allows resizing the virtual terminal window dynamically by
200 | specifying new width (`cols`) and height (`rows`).
201 |
202 | ```json
203 | { "type": "resize", "cols": 80, "rows": 24 }
204 | ```
205 |
206 | This command triggers `resize` event.
207 |
208 | ### WebSocket API
209 |
210 | The WebSocket API currently provides 2 endpoints:
211 |
212 | #### `/ws/events`
213 |
214 | This endpoint allows the client to subscribe to events that happen in ht.
215 |
216 | Query param `sub` should be set to a comma-separated list of desired events.
217 | E.g. `/ws/events?sub=init,snapshot`.
218 |
219 | Events are delivered as JSON encoded strings, using WebSocket text message type.
220 |
221 | See [events](#events) section below for the description of all available events.
222 |
223 | #### `/ws/alis`
224 |
225 | This endpoint implements JSON flavor of [asciinema live stream
226 | protocol](https://github.com/asciinema/asciinema-player/blob/develop/src/driver/websocket.js),
227 | therefore allows pointing asciinema player directly to ht to get a real-time
228 | terminal preview. This endpoint is used by the live terminal preview page
229 | mentioned above.
230 |
231 | ### Events
232 |
233 | The events emitted to STDOUT and via `/ws/events` WebSocket endpoint are
234 | identical, i.e. they are JSON-encoded objects with the same fields and payloads.
235 |
236 | Every event contains 2 top-level fields:
237 |
238 | - `type` - type of event,
239 | - `data` - associated data, specific to each event type.
240 |
241 | The following event types are currently available:
242 |
243 | #### `init`
244 |
245 | Same as `snapshot` event (see below) but sent only once, as the first event
246 | after ht's start (when sent to STDOUT) and upon establishing of WebSocket
247 | connection.
248 |
249 | #### `output`
250 |
251 | Terminal output. Sent when an application (e.g. shell) running under ht prints
252 | something to the terminal.
253 |
254 | Event data is an object with the following fields:
255 |
256 | - `seq` - a raw sequence of characters written to a terminal, potentially including control sequences (colors, cursor positioning, etc.)
257 |
258 | #### `resize`
259 |
260 | Terminal resize. Send when the terminal is resized with the `resize` command.
261 |
262 | Event data is an object with the following fields:
263 |
264 | - `cols` - current terminal width, number of columns
265 | - `rows` - current terminal height, number of rows
266 |
267 | #### `snapshot`
268 |
269 | Terminal window snapshot. Sent when the terminal snapshot is taken with the
270 | `takeSnapshot` command.
271 |
272 | Event data is an object with the following fields:
273 |
274 | - `cols` - current terminal width, number of columns
275 | - `rows` - current terminal height, number of rows
276 | - `text` - plain text snapshot as multi-line string, where each line represents a terminal row
277 | - `seq` - a raw sequence of characters, which when printed to a blank terminal puts it in the same state as [ht's virtual terminal](https://github.com/asciinema/avt)
278 |
279 | ## Testing on command line
280 |
281 | ht is aimed at programmatic use given its JSON-based API, however one can play
282 | with it by just launching it in a normal desktop terminal emulator and typing in
283 | JSON-encoded commands from keyboard and observing the output on STDOUT.
284 |
285 | [rlwrap](https://github.com/hanslub42/rlwrap) can be used to wrap STDIN in a
286 | readline based editable prompt, which also provides history (up/down arrows).
287 |
288 | To use `rlwrap` with `ht`:
289 |
290 | ```sh
291 | rlwrap ht [ht-args...]
292 | ```
293 |
294 | ## Python and Typescript libs
295 |
296 | Here are some experimental versions of a simple Python and Typescript libraries that wrap `ht`: [htlib.py](https://github.com/andyk/headlong/blob/24e9e5f37b79b3a667774eefa3a724b59b059775/packages/env/htlib.py) and a [htlib.ts](https://github.com/andyk/headlong/blob/24e9e5f37b79b3a667774eefa3a724b59b059775/packages/env/htlib.ts).
297 |
298 | TODO: either pull those into this repo or fork them into their own `htlib` repo.
299 |
300 | ## Possible future work
301 |
302 | * update the interface to return the view with additional color and style information (text color, background, bold/italic/etc) also in a simple JSON format (so no dealing with color-related escape sequence either), and the frontend could render this using HTML (e.g. with styled pre/span tags, similar to how asciinema-player does it) or with SVG.
303 | * support subscribing to view updates, to avoid needing to poll (see [issue #9](https://github.com/andyk/ht/issues/9))
304 | * native integration with asciinema for recording terminal sessions (see [issue #8](https://github.com/andyk/ht/issues/8))
305 |
306 | ## Alternatives and related projects
307 | [`expect`](https://core.tcl-lang.org/expect/index) is an old related tool that let's you `spawn` an arbitrary binary and then `send` input to it and specify what output you `expect` it to generate next.
308 |
309 | Also, note that if there exists an explicit API to achieve your given task (e.g. a library that comes with the tool you're targeting), it will probably be less bug prone/finicky to use the API directly rather than working witht your tool through `ht`.
