JavaScript • Mercari, Inc.

I did it
Today’s theme
Debug
Debugging method • Using var_dump, echo • php -a •
Writing tests • IDE • etc…
Debugging method • Using var_dump, echo • php -a •
Writing tests • IDE • etc…
Using REPL (php -a) • Easy to use • Can
load files • Good integration with CLI
Is it the best way? • Bother to require autoloader
• Reset state every time • Not good for many autoloader files…
None
psysh http://psysh.org/
psysh • Rich CLI • Customizable • We can make
own REPL
Rich REPL • Auto complete (with Tab key) • Useful
commands • history, documentation, show properties • Rich UI
Customizable • We can place config file • ~/.config/psysh/psysh.php •
We can do anything if PHP can
<?php // Automatically autoload Composer dependencies if (is_file(getcwd() . '/vendor/autoload.php'))
{ require_once(getcwd() . '/vendor/autoload.php'); } Load composer automatically
<?php // Use local config, if available if (is_file(getcwd() .
'/.psysh.php')) { return require(getcwd() . '/.psysh.php'); } // Fall back to global config return [ 'startupMessage' => '<info>Using global config</info>', 'commands' => [ new \Psy\Command\ParseCommand, ], ]; Load local config
<?php $default_includes = []; // Automatically autoload Composer dependencies if
(is_file(getcwd() . '/vendor/autoload.php')) { $default_includes[] = getcwd() . '/vendor/autoload.php'); } if (array_pop(explode('/', getcwd())) === '') { $default_includes[] = getcwd() . 'lecacy_autoloader.php'; } return [ 'defaultIncludes' = $default_includes, ]; Legacy project? No problem☺
Thank you
