Glitch
Better tools for when things go wrong
Glitch is a standalone PHP package designed to dramatically improve error handling and inspection when developing your applications.
The project aims to provide deep data inspection tools and an Exception handling interface.
Get news and updates on the DecodeLabs blog.
Installation
Glitch should be installed via composer
Usage
Glitch uses Veneer with its frontage registered at DecodeLabs\Glitch
.
You can access all of the primary functionality through this frontage:
Setup
Otherwise, Glitch works out of the box without any special setup. There are however some optional steps you can take to customise operation.
Register as the default error handler:
Register base path aliases for easier reading of file names in dumps:
Pass the microtime()
of initial app launch for timing purposes:
Set run mode (development | testing | production
) so Glitch can format output correctly:
Dumps
Dump anything and everything easily, using simple global functions. The functions mirror those used in Symfony/VarDumper, maintaining compatibility by using Symfony's VarDumper interface if it is already loaded.
You can also mark functions as incomplete whilst in development:
Renderers
The resulting dump UI (when using the HTML renderer, the default option) is injected into an iframe at runtime so can be rendered into any HTML page without breaking anything. If the page is otherwise empty, the iframe will expand to fill the viewport if possible.
The dump output is rendered by an instance of DecodeLabs\Glitch\Renderer
which can be overridden on the default Context
at startup. The Html
renderer is loaded under http sapi, the Cli
renderer is used when under the CLI sapi.
Custom renderers may convert Entities
to other output formats depending on where they should be sent, such as Xml or Json for example.
Custom colours
The HTML renderer uses css variables to style individual element colours and can be overridden with custom values. Create a custom css file with variable overrides:
See colours.scss for all of the current colour override options.
Then load the file into the HTML renderer:
Transports
Once rendered, the dump information is delivered via an instance of DecodeLabs\Glitch\Transport
, also overridable on the default Context
. It is the responsibility of the Transport
to deliver the rendered dump.
By default, the render is just echoed out to STDOUT
, however custom transports may send information to other interfaces, browser extensions, logging systems, etc.
Custom dumps
You can customise how your own class instances are dumped by implementing DecodeLabs\Glitch\Dumpable
and / or providing a glitchDump
method.
The method should either yield or return a list of key / value pairs that populate the requisite fields of the dumper entity.
The Dumpable
interface is NOT required - Glitch will check for the existence of the method regardless, which is useful if you do not want to rely on a dependency on the Glitch library just to provide better dump handling.
However, the Dumpable
interface is provided by glitch-support package which contains only the bear essentials for libraries to provide support to Glitch without including the entire library as a dependency.
