PackageFactory.Fusion.Debug

Provides simple methods to debug stuff in Fusion

This package allows you to debug values in fusion as simple as:

debug = ${Debug.var_dump(node).var_dump(request).die()}

Installation

composer require --dev packagefactory/fusion-debug

Dump Values

var_dump

You can use Debug.var_dump(...) to show debug information on any value you pass as a first parameter.

var_dump = ${Debug.var_dump(myValue)}

Debug.var_dump(...) accepts the following parameters:

• $value : mixed - The value to debug
• $title : string (optional) - A human-readable title to better recognize the debug output when in a crowded context
• $plaintext : boolean (optional, default = false) - If true, the output won't be HTML but plain text
• $pre : boolean (optional, default = true) - If true and $plaintext is true as well, the output will be wrapped in a <pre>-Tag

To show multiple debug outputs in a row, Debug.var_dump(...) calls can be chained arbitrarily:

var_dump = ${Debug.var_dump(myValue).var_dump(myOtherValue)}

print_r

Debug.print_r(...) is a small wrapper around the print_r function of the PHP standard library.

print_r = ${Debug.print_r(myValue)}

However, the signature of Debug.print_r(...) deviates a little and accepts the following parameters:

• $value : mixed - The value to debug
• $pre : boolean (optional, default = true) - If true, the output will be wrapped in a <pre>-Tag

To show multiple debug outputs in a row, Debug.print_r(...) calls can be chained arbitrarily:

print_r = ${Debug.print_r(myValue).print_r(myOtherValue)}

var_export

Debug.var_export(...) is a small wrapper around the var_export function of the PHP standard library.

var_export = ${Debug.var_export(myValue)}

However, the signature of Debug.var_export(...) deviates a little and accepts the following parameters:

• $value : mixed - The value to debug
• $pre : boolean (optional, default = true) - If true, the output will be wrapped in a <pre>-Tag

To show multiple debug outputs in a row, Debug.var_export(...) calls can be chained arbitrarily:

var_export = ${Debug.var_export(myValue).var_export(myOtherValue)}

xdebug_var_dump

Debug.xdebug_var_dump(...) is a small wrapper around the xdebug_var_dump function of the XDebug PHP extension. If that extension is not enabled, Debug.xdebug_var_dump(...) will fall back to the var_dump function of the PHP standard library.

xdebug_var_dump = ${Debug.xdebug_var_dump(myValue)}

However, the signature of Debug.xdebug_var_dump(...) deviates a little and accepts the following parameters:

• $value : mixed - The value to debug
• $pre : boolean (optional, default = true) - If true, the output will be wrapped in a <pre>-Tag

To show multiple debug outputs in a row, Debug.xdebug_var_dump(...) calls can be chained arbitrarily:

xdebug_var_dump = ${Debug.xdebug_var_dump(myValue).xdebug_var_dump(myOtherValue)}

Debug Fusion Objects

fusionPath

You can use Debug.fusionPath(...) to get the current fusion path of a particular fusion object (most commonly it will be this).

fusionPath = ${Debug.var_dump(Debug.fusionPath(this))}

Debug.fusionPath(...) accepts the following parameters:

• $fusionObject : AbstractFusionObject - The fusion object to get the fusion path from (when in doubt, use this)

Interrupting program execution

exit

You can use Debug.exit() to stop execution of the PHP Script entirely (just as with the exit function of the PHP standard library).

Debug.exit() takes no parameters.

Debug.exit() can be used in any chain of Debug.var_dump(...), Debug.print_r(...), Debug.var_export(...) or Debug.xdebug_var_dump(...) calls:

debug = ${Debug.var_dump(node).var_dump(request).die()}

die

Debug.die() is an alias for Debug.exit().
