Logging

PicoFeed log in memory the execution flow, if a feed doesn't work correctly it's easy to see what is wrong.

Reading messages

use PicoFeed\Logging\Logger;

// All messages are stored inside an Array
print_r(Logger::getMessages());

You will got an output like that:

Array
(
    [0] => Fetch URL: http://petitcodeur.fr/feed.xml
    [1] => Etag:
    [2] => Last-Modified:
    [3] => cURL total time: 0.711378
    [4] => cURL dns lookup time: 0.001064
    [5] => cURL connect time: 0.100733
    [6] => cURL speed download: 74825
    [7] => HTTP status code: 200

Remove messages

All messages are stored in memory, if you need to clear them just call the method Logger::deleteMessages():

Logger::deleteMessages();

Command line utility

PicoFeed provides a basic command line tool to debug feeds quickly. The tool is located in the root directory project.

Usage

$ ./picofeed
Usage:
./picofeed feed <feed-url>                   # Parse a feed a dump the ouput on stdout
./picofeed debug <feed-url>                  # Display all logging messages for a feed
./picofeed item <feed-url> <item-id>         # Fetch only one item
./picofeed nofilter <feed-url> <item-id>     # Fetch an item but with no content filtering

$ ./picofeed debug https://linuxfr.org/
