I ran into a little problem adding php -l to a Makefile. PHP lint is a little verbose outputting “No syntax errors detected” for every file that has no problems. I don’t really want that output but getting rid of it with grep -v means that make treats no errors (grep didn’t find any lines to show) as a failure and errors (grep found some lines to show) as a success. make then terminates in the success case and continues or exits with success in the failure case!

lint:
	@! find . -name "*.php" | grep -v "^./vendor" | xargs -I{} php -l '{}' | grep -v "No syntax errors detected"

The trick is to negate the exit code of the entire pipeline like so:

lint:
	@! find . -name "*.php" | grep -v "^./vendor" | xargs -I{} php -l '{}' | grep -v "No syntax errors detected"

I was reading about Gill Sans and I looked at the sweet Penguin cover in that article and I wondered if I could do the same in CSS.

Here’s my attempt:

You can see it on it’s own page at bluebones.net/penguin.

All the libraries I found via $ composer search required coding to work. But csrf-magic only requires that you include the project file and everything else happens magically. (Behind the scenes it adds a hidden __csrf_magic form element to all forms). This does mean that error handling is by default kind of ugly, but there’s a hook to change that should you wish.

MacVim is the de facto standard vim for OS X now. But you don’t necessarily want to run it as a separate GUI application. If you’re making a quick edit in a terminal you want to stay in the terminal environment.

You can achieve this with mvim -v {filename} where mvim is this shell script.

• Install a version with vim with +clipboard. You can check your current setting with :echo has('clipboard'). “1” is good, “0” is bad. This lets you access the system clipboard with (for example) “+p to paste.
• Add clipboard=unnamed to .vimrc and restart vim. You are now using the system clipboard by default for all cut/copy/paste operations.

I’ve always admired the simplicity of Mustache templates but the complication of internationalization support has always prevented me using them until a recent project. I used them in my Magic: the Gathering tournament software.

Mustache templates look like this:

<h2>Create Event</h2>

<form action="{{formAction}}" method="post">
  <label for="format">Format</label> <input type="text" name="format">
  <label for="cost">Cost</label> <input type="text" name="cost">
  <input class="btn btn-primary btn-block" type="submit">
</form>

You can see a bunch from the project at https://github.com/bakert/tournament/tree/master/views.

As long as you have { "require": { "mustache/mustache": "~2.5" } } in your composer.json using them is as simple as:

$loader = new Mustache_Loader_FilesystemLoader('path/to/templates');
$engine = new Mustache_Engine(['loader' => $loader]);
echo $engine->render('template_name', $arguments);

I wrapped this up in a class (Template) and a global (T()) so I could make calls like this:

echo T()->signin($args);

class HttpStream {

    public class go($url) {
        $ch = curl_init($url);
        curl_setopt($ch, CURLOPT_WRITEFUNCTION, array($this, 'streamHandler'));
        curl_exec($ch);
        curl_close($ch);
    }

    protected function streamHandler($ch, $data) {
        // Handle the stream here
        // ...
        return strlen($data); // strlen($data) to continue streaming or return another value to end the stream.
    }
}
