Thesis Hot Reload
=================

[](#thesis-hot-reload)

Watches files for changes and automatically restarts a command.

Useful for development servers, workers, or any long-running PHP tasks.

Supports debouncing to avoid redundant restarts when multiple files change at once.

Installation
------------

[](#installation)

```
composer require thesis/hot-reload --dev
```

Requires PHP 8.4+.

Usage
-----

[](#usage)

```
vendor/bin/hot-reload [options] [--]
```

### Options

[](#options)

OptionDescriptionDefault`--path`Paths to watch (repeatable)`src``--ext`File extensions to watch (repeatable; if none, all are watched)none`--exclude`Patterns to exclude (repeatable, e.g. `*.generated.php`)none`--debounce`Delay in seconds before restarting after a change`0.1``--term-timeout`Seconds to wait for the process to exit after `SIGTERM` before sending `SIGKILL``3``--forward-signal`Signals to forward to the process (repeatable, e.g. `SIGUSR1` or `10`)none### Exit code

[](#exit-code)

`vendor/bin/hot-reload` returns the exit code of the watched command if it terminated on its own, or `0` when stopped via `SIGINT` or `SIGTERM`.

### Examples

[](#examples)

```
# Watch src/, restart on any file change
vendor/bin/hot-reload -- php server.php

# Watch multiple paths, only .php files
vendor/bin/hot-reload --path=src --path=config --ext=php -- php server.php

# Exclude generated files
vendor/bin/hot-reload --path=src --ext=php --exclude='*.generated.php' -- php server.php

# Increase debounce delay (useful when many files change at once)
vendor/bin/hot-reload --debounce=0.5 -- php server.php
```

PHP API
-------

[](#php-api)

You can use `hotReload()` directly in PHP instead of the bin script:

```
use Amp\Cancellation;
use Amp\Http\Server\SocketHttpServer;
use function Amp\ByteStream\getStdout;
use function Amp\trapSignal;
use function Thesis\hotReload;

hotReload(
    files: __DIR__,
    task: static function (Cancellation $termination): void {
        $server = SocketHttpServer::createForDirectAccess(/** ... */);

        $termination->subscribe($server->stop(...));

        $server->expose(/** ... */);

        $server->start(/** ... */);

        trapSignal([SIGINT, SIGTERM], cancellation: $termination);

        $server->stop();
    },
    onReload: static function (): void {
        getStdout()->write("\nFiles changed, reloading server...\n\n");
    },
);
```

`$termination` is cancelled when files change or when `hotReload()` itself is cancelled — subscribe to it to stop the task gracefully.

### TransparentProcess

[](#transparentprocess)

Use [`TransparentProcess::start()`](src/HotReload/TransparentProcess.php) to run an external command with full TTY transparency:

- stdin/stdout/stderr are inherited
- specified signals are forwarded
- the process is terminated gracefully via `SIGTERM`
- `SIGKILL` is dispatched after a timeout.

See [`bin/hot-reload`](bin/hot-reload) for a real-world usage example.

Roadmap
