FAQ
----

### How do I update my feeds with a cronjob?

You just need to be inside the directory `miniflux` and run the script `cronjob.php`.

Parameters          | Type         		             | Value
--------------------|--------------------------------|-----------------------------
--limit             | optional                       | number of feeds
--call-interval     | optional, excluded by --limit, require --update-interval | time in minutes < update interval time
--update-interval   | optional, excluded by --limit, require --call-interval   | time in minutes >= call interval time


Examples:

    crontab -e

    # Update all feeds
    0 */4 * * *  cd /path/to/miniflux && php cronjob.php >/dev/null 2>&1

	# Update the 10 oldest feeds each time
    0 */4 * * *  cd /path/to/miniflux && php cronjob.php --limit=10 >/dev/null 2>&1

	# Update all feeds in 60 minutes (updates the 8 oldest feeds each time with a total of 120 feeds).
    * */4 * * *  cd /path/to/miniflux && php cronjob.php --call-interval=4 --update-interval=60 >/dev/null 2>&1

Note: cronjob.php can also be called from the web; in this case specify the options as GET variables.
Example: <http://yourpersonalserver/miniflux/cronjob.php?call-interval=4&update-interval=60>

### How does Miniflux update my feeds from the user interface?

Miniflux uses an Ajax request to refresh each subscription.
By default, there is only 5 feeds updated in parallel.

### I have 600 subscriptions, can Miniflux handle that?

Your life is cluttered.

### Why are there no categories? Why is feature X missing?

Miniflux is a minimalist software. Less is more.

### I found a bug, what next?

Report the bug to the [issues tracker](https://github.com/fguillot/miniflux/issues) and I will fix it.

You can report feeds that doesn't works properly too.

### Which browser is compatible with Miniflux?

Miniflux is tested with the latest versions of Mozilla Firefox, Google Chrome and Safari.

I don't use Microsoft products, then I have no idea if Miniflux works correctly with Internet Explorer.

### How to override application variables?

There is few settings that can't be changed by the user interface.
These parameters are defined with PHP constants.

To override them, create a `config.php` file at the root of the project and change yourself the values.

By example, to override the default HTTP timeout value:

    <?php

    // My specific HTTP timeout (5 seconds)
    define('HTTP_TIMEOUT', 5);

PS: This file must be a PHP file (nothing before the open tag `<?php`).

Actually, the following constants can be overrided:

- `HTTP_TIMEOUT` => default value is 10 seconds
- `APP_VERSION` => default value is master
- `DB_FILENAME` => default value is `data/db.sqlite`
- `DEBUG` => default is false (enable logs dump of picoFeed)
- `DEBUG_DIRECTORY` => default is /tmp (place to store log files)
- `THEME_DIRECTORY` => default is themes
- `SESSION_SAVE_PATH` => default is empty (used to store session files in a custom directory)

### How to change the session save path?

With several shared hosting providers, sessions are cleaned frequently, to avoid to login too often,
you can save sessions in a custom directory.

- Create a directory, by example `sessions`
- This directory must be writeable by the web server user
- This directory must NOT be accessible from the outside world (add a `.htaccess` if necessary)
- Override the application variable like described above: `define('SESSION_SAVE_PATH', 'sessions');`
- Now, your sessions are saved in the directory `sessions`

### How to override/extends the content filtering blacklist/whitelist?

Miniflux use [PicoFeed](https://github.com/fguillot/picoFeed) to parse the content of each item.
These variables are public static arrays, extends the actual array or replace it.

**Be careful, you can break everything by doing that!!!**

Put your modifications in your custom `config.php` like described above.

By example to add a new iframe whitelist:

    \PicoFeed\Filter::$iframe_whitelist[] = 'http://www.kickstarter.com';

Or to replace the entire whitelist:

    \PicoFeed\Filter::$iframe_whitelist = array('http://www.kickstarter.com');

Available variables:

    // Allow only specified tags and attributes
    \PicoFeed\Filter::$whitelist_tags

    // Strip content of these tags
    \PicoFeed\Filter::$blacklist_tags

    // Allow only specified URI scheme
    \PicoFeed\Filter::$whitelist_scheme

    // List of attributes used for external resources: src and href
    \PicoFeed\Filter::$media_attributes

    // Blacklist of external resources
    \PicoFeed\Filter::$media_blacklist

    // Required attributes for tags, if the attribute is missing the tag is dropped
    \PicoFeed\Filter::$required_attributes

    // Add attribute to specified tags
    \PicoFeed\Filter::$add_attributes

    // Attributes that must be integer
    \PicoFeed\Filter::$integer_attributes

    // Iframe allowed source
    \PicoFeed\Filter::$iframe_whitelist

For more details, have a look to the class `vendor/PicoFeed/Filter.php`.

### How to create a theme for Miniflux?

It's very easy to write a custom theme for Miniflux.

A theme is just a CSS file, images and fonts.
A theme doesn't change the behaviour of the application but only the page design.

The first step is to create a new directory structure for your theme:

    mkdir -p themes/mysuperskin/{css,img,fonts}

The name of your theme should be only alphanumeric.
There is the following directories inside your theme:

- `css`: Your stylesheet, the file must be named `app.css` (required)
- `img`: Theme images (not required)
- `fonts`: Theme fonts (not required)

For a very basic theme example, have a look to the directory `examples\mytheme`.

Miniflux use responsive design, so it's better if your theme can handle mobile devices.

If you write a very cool theme for Miniflux, **send me your code to be available in the default installation!**
It would be awesome for everybody :)
