cli

@astx/cli

Command-line interface for the ASTX toolchain. Compile, run, and inspect .astx binary files.

---

Installation

npm install -g @astx/cli

---

Commands

astx compile <input> <output>

Compile a JavaScript file to an ASTX binary.

astx compile src/index.js dist/index.astx

The .astx extension is appended automatically if omitted from <output>.

--watch / -w

Watch the input file and recompile automatically on every save.

astx compile --watch src/index.js dist/index.astx

Each recompile prints a timestamped line:

Watching src/index.js for changes… (Ctrl+C to stop)
[12:34:56] Compiled src/index.js → dist/index.astx in 12.4ms
[12:35:02] Compiled src/index.js → dist/index.astx in 11.9ms

Compile errors during watch are printed without stopping the watcher.

---

astx run <file>

Execute an ASTX binary file.

astx run dist/index.astx

The program runs in vm mode; __dirname and __filename are injected based on the file's location.

---

astx gen <input> <output>

Decompile an ASTX binary back to JavaScript source. The output is not optimised or human-readable — intended for debugging only.

astx gen dist/index.astx dist/index.debug.js

---

astx version

Print the installed versions of the CLI and compiler.

astx version
