Configuration Reference

Bootstrap Configuration

These configuration options are special configuration options only configurable through environment variables (e.g. through the .env file).

There are no corresponding configuration options for these values in the app/config definitions because they are applied before the application container (and configuration) is loaded.

`FILES_PATH`

A path (relative or absolute) to the directory in which you would like to list. This may even be a path outside of the application directory. When left unset, the root application directory (i.e. the folder where index.php is located) will be listed.

An absolute or relative file path (string)

<unset>

`COMPILE_CONTAINER`

Whether or not the application container will be compiled. When set to false the container will not be compiled and cached. If left unset the container will be compiled and cached on first run and the cached container will be reused on subsequent requests. Disabling this comes with a (likely negligible) performance hit. Generally this should not be changed but might be necessary to modify when running Directory Lister on a read-only filesystem.

false or <unset>

<unset>

Runtime Configuration

General application runtime configuration can be controlled through environment variables. This can be accomplished via an .env file located in the root of your application. An example file is provided as .env.example.

Advanced configuration can be accomplished via the app config located at app/config/app.php. However, changes to this fill will need to be manually re-applied between upgrades. It is highly recommended to stick to environment variables for controlling app configuration unless absolutely necessary.

`APP_DEBUG`

Enable application debugging and display error messages.

It is recommended that debug remains OFF unless troubleshooting an issue. Leaving this enabled WILL cause leakage of sensitive server information.

true or false

false

`APP_LANGUAGE`

The application's interface language.

See the app/translations folder for available translations.

en (English)

`DATE_FORMAT`

The format used for rendering dates in the application views.

See the PHP date format documentation for possible values.

Y-m-d H:i:s

`DIRECT_LINKS`

Comma separated list of file matching patterns to be directly linked. Directly linked files will not be served by Directory Lister but handled by the web server directly.

This setting has no effect when FILES_PATH is set or when used in the Docker container.

Example

To directly link all .htm, .html one or more folders deep and .php files in all folders and sub-folders.

DIRECT_LINKS=**/index.{htm,html},**.php

A comma separated list of file matching patterns.

`HIDDEN_FILES_LIST`

`MAX_HASH_SIZE`

The maximum file size (in bytes) that can be hashed. This helps to prevent timeouts for excessively large files.

Cache Configuration

Application cache configuration is also controlled through environment variables. This can be accomplished via an .env file located in the root of your application. An example file is provided as .env.example.

Advanced configuration can be accomplished via the cache config located at app/config/cache.php. However, changes to this fill will need to be manually re-applied between upgrades. It is highly recommended to stick to environment variables for controlling cache configuration unless absolutely necessary.

`CACHE_LIFETIME`

The app cache lifetime (in seconds). Setting this value to 0 will cache indefinitely.

Any positive integer

A directory path as a string or false to disable the view cache entirely

app/cache/views

Icon Configuration

The icon config is located at app/config/icons.php. Here is were file types are mapped to their respective icons. The mapping is a PHP array where the array key is the file extension (without a preceding dot) and the array value is the desired Font Awesome class names.

icons.php

return [
    'icons' => [
        '7z' => 'fas fa-file-archive',
        'aac' => 'fas fa-music',
        'accdb' => 'fas fa-database',
        'ai' => 'fas fa-image',
        'aif' => 'fas fa-music',
        'apk' => 'fab fa-android',
        'app' => 'fas fa-window',
        'avi' => 'fas fa-video',
        'bak' => 'fas fa-save',
        'bat' => 'fas fa-terminal',
        // etc...
    ],
];

Advanced Configuration

Some configuration values do not have a corresponding variable. These values can only be controlled through their entries in the app/config files.

`hidden_files`

Array of hidden file definitions. Will be merged with definitions in the file defined in the hidden_files_list configuration option. Supports glob patterns (e.g. *.txt, file.{yml,yaml}, etc.).

See the Hiding Files page for additional info on hiding files.

An array of paths (strings)

[] (an empty array)

'hidden_files' => [
    'somefile.txt', // Matches 'somefile.txt' exactly
    'README.*', // Matches files named 'README' with any file extension
    'foo/*', // Matches all files in the 'foo' directory
    'schema.{ya?ml}', // Matches 'schema.yml' or 'schema.yaml'
]

`memcached_config`

The Memcached configuration anonymous function (closure). This option is used when the cache_driver configuration option is set to memcached. The closure receives a Memcached object as it's only parameter. You can use this object to configure the Memcached connection. At a minimum you must connect to one or more Memcached servers via the addServer() or addServers() methods.

Reference the PHP Memcached documentation for Memcached configuration options.

An anonymous function that receives a Memcached object

function (Memcached $memcached): void {
    // Configure the $memcached object
}

DI\value(function (Memcached $memcached, Config $config): void {
    $memcached->addServer(
        $config->get('memcached_host'),
        $config->get('memcached_port')
    );
})

This closure adds a single connection to a server at the host defined by memcached_host on the port defined by memcached_port.

Uses the MEMCACHED_HOST and MEMCACHED_PORT variables by default

`redis_config`

The Redis configuration anonymous function (closure). This option is used when the cache_driver configuration option is set to redis. The closure receives a Redis object as it's only parameter. You can use this object to configure the Redis connection. At a minimum you must connect to one or more Redis servers via the connect() or pconnect() methods.

Reference the phpredis documentation for Redis configuration options.

An anonymous function that receives a Redis object

function (Redis $redis): void {
    // Configure the $redis object
}

DI\value(function (Redis $redis, Config $config): void {
    $redis->pconnect(
        $config->get('redis_host'),
        $config->get('redis_port')
    );
})

This closure adds a single connection to a server at the host defined by redis_host on the port defined by redis_port.

Uses the REDIS_HOST and REDIS_PORT variables by default

`http_cache`

HTTP cache values for controlling browser page cache duration. An array of mime types mapped to their cache duration in seconds.

An array of mime types mapped to their cache duration as a seconds (integers).

[
    'application/json' => 300,
    'application/zip' => 300,
]

`sort_order`

An anonymous function can be used to customize the sort order of files and folders in your directory listing. The anonymous function receives two SplFileInfo objects as arguments and must return an integer less than, equal to, or greater than zero to represent the first argument being respectively less than, equal to, or greater than the second.

'sort_order' => \DI\value(
    function (SplFileInfo $file1, SplFileInfo $file2): int {
        return strcmp($file1->getRealPath(), $file2->getRealPath());
    })
);

The anonymous function must be wrapped in a \DI\value() function.
