Web App Starter

Simple web app starter package, expects to run in a domain's root directory.

Add this to your nginx config to protect sensitive data directories:

       
	location /private/ {
		deny all;
		return 404;
	}

	location /.git {
		deny all;
		return 404;
	}
	

Routing

URL::MakeRoute() creates URL::$route data. For example, a request to http://example.com/some/url/path would look like this:

Array
(
    [page] => index
    [l-path] => some/url/path
)

The page key refers to the view should be rendered. By default, this is just 'index', leading to 'views/index.php' getting invoked. If the URL's path element starts with a colon, the entire path is used as the page value.

The l-path key refers to the actual URL path as given by the browser. For example, the 'views/index.php' view uses this to invoke the correct sub-view.

Components

This uses the idea of immediate components to render HTML. For example, a given view may look like this:

<? return(function($prop) { ?>

<!doctype html><html><head>
    <meta http-equiv="content-type" content="text/html; charset=utf-8">
  </head>
  <body>  
    <?= component('nav/shortcut-bar') ?>
    <?= component('nav/menu', 'menu') ?>
    <?= component('nav/content', array('id' => 'content')) ?>
  </body>  
</html><? });

This would in turn render the components 'nav/shortcut-bar', 'nav/menu', and 'nav/content'. Components are located in views/. The function signature of a component() call looks like this:

component($file_name, $id_override = false, $prop = array())

$file_name is the component's file name withint views/. Invoking the component() executes that file. If the file returns a lambda function, that function gets called every time the component is invoked. If the file returns a text, that text gets returned every time the component is invoked.

$prop is an optional parameter to communicate further parameters to the component, and this corresponds to the $prop parameter being passed to a component's lambda function.

Logging

This package includes a very basic Log class.

Log::debug($module, $text) /* writes to log/debug.[Y]-[m].log */
Log::text($module, $text)   /* writes to log/log.[Y]-[m].log */
Log::audit($module, $text) /* writes to system journal */

$module should be a short string identifying the module or context of the log line.

$text text to be logged.

Profiler

A basic profiling fixture.

Profiler::log($text, $backtrace = false) 

$text name/text describing the checkpoint to be profiled. $backtrace optional data attachment.

Profiler logs are not committed to disk. Log data for the current request is stored in Profiler::$log.

ulib Convenience Functions

function first($p1, ...)

Takes any number of parameters and returns the first that is not null or empty.

function write_to_file($filename, $content)

Appends $content to $filename.

function map($list, $func)

Performs a map operation on $list using the $func predicate and returns a new array with the result.

function reduce($list, $func)

Like map() but only adds results on entries where $func does not return null.

function cfg($key)

Shortcut for accessing the configuration global $GLOBALS['config']. For example, a $key of 'db/host' would translate to $GLOBALS['config']['db']['host'].

function nibble($segdiv, &$cake, &$found = false)

Cuts off the part of &$cake before the first occurrence of $segdiv, and returns that part.

function starts_with($s, $match) / function ends_with($s, $match)

Returns true if $s starts/ends with $match.
