README
PSR-3 logger for adding colors and indentation on PHP CLI output.
Description
Use tags and placeholder syntax to provide an easy way to color and indent PHP CLI output. PSR-3 compatibility allows graceful degradation when switching to another PSR-3 compliant logger.
Colors
- Declare some colors:
$aConfig = array( 'colors' => array( 'debug' => "\033[0;35m", 'error' => "\033[1;31m", 'section' => "\033[1;37m", 'subsection' => "\033[1;33m", 'ok' => "\033[1;32m" ) ); $oLogger = new ColoredIndentedLogger($aConfig);
- Use them either by exploiting placeholder syntax with
'C.'
prefix:
$oLogger->info('{C.section}Start of new section'); $oLogger->info('Result is {C.ok}OK');
Or by logging message with a level equals to a color key:
$oLogger->debug('some debug information…'); $oLogger->error(new \RuntimeException('Arghhhh!'));
It is even possible to specify color tag in the value of a placeholder:
$oLogger->info('Result is {result}', array('result' => '{C.ok}OK'));
See below for demonstration.
Indentation
You can control indentation level with indent and unindent tags:
- default tags are
'+++'
and'---'
, - both usable at the beginning or at the end of any message,
- one or more occurrences,
- can be used alone.
Example:
$oLogger->info('Section A+++'); $oLogger->info('Subsection+++'); $oLogger->info('Step 1'); $oLogger->info('Step 2'); $oLogger->info('------Section B+++');
See below for demonstration.
Configuration
Default configuration:
array( 'colors' => array(), 'base_indentation' => "\033[0;30m┆\033[0m ", 'indent_tag' => '+++', 'unindent_tag' => '---', 'min_message_level' => \Psr\Log\LogLevel::DEBUG, 'reset_color_sequence' => "\033[0m", 'color_tag_prefix' => 'C.' );
Where:
colors
⇒(array)
Array of key/value pairs to associate bash color codes to color tags (see above).base_indentation
⇒(string)
Describe what is a simple indentation, e.g."\t"
.indent_tag
⇒(string)
Tag usable at the start or at the end of the message to add one or more indentation level.unindent_tag
⇒(string)
Tag usable at the start or at the end of the message to remove one or more indentation level.min_message_level
⇒(string)
Threshold required to log message, must be defined in\Psr\Log\LogLevel
.reset_color_sequence
⇒(string)
Concatenated sequence at the end of message when colors are used. For example:"\033[0m"
.color_tag_prefix
⇒(string)
Prefix used in placeholders to distinguish standard context from colors.

Usage
- Class autoloading and dependencies are managed by Composer so install it following the instructions on Composer: Installation - *nix or just run the following command:
$ curl -sS https://getcomposer.org/installer | php
- Add dependency to
GAubry\Logger
into require section of yourcomposer.json
:
{ "require": { "geoffroy-aubry/logger": "1.*" } }
and run php composer.phar install
from the terminal into the root folder of your project.
- Include Composer's autoloader and use the
GAubry\Logger
class:
<?php require_once 'vendor/autoload.php'; use GAubry\Logger\ColoredIndentedLogger; $aConfig = array(…); $oLogger = new ColoredIndentedLogger($aConfig); $oLogger->info('Hello'); …

$ php vendor/bin/phpunit --configuration phpunit.xml
-
Coding standards with PHP CodeSniffer:
$ php vendor/bin/phpcs --standard=PSR2 src/ tests/ -v
-
