I think this is totally reasonable, although maybe just having D11661 (which is probably a rare special case) provide a no-op stub would be slightly cleaner on the balance.

src/xsprintf/xsprintf.php

This is also technically wrong, now.

epriestley added a comment.Feb 9 2015, 3:00 PM

The ability to use a callback here to eventually handle %17$s and %'%3.3d in the linter (I think both are possible) is maybe an argument for using a stub instead of allowing null.

joshuaspence added a comment.Feb 9 2015, 8:19 PM

Yeah, I might just use the no-op stub.

Interesting. I thought that this would fail if $callback was array($this, 'xsprintfCallback') but PHP is fine with this.

Only since PHP 5.3. 5.2 requires a string for dynamic function calls.

joshuaspence added a comment.Feb 9 2015, 8:47 PM

Ah interesting. In this case, I will need to change this to call_user_func for D11661.

epriestley added a comment.Feb 9 2015, 8:57 PM

That's probably a good idea anyway, the $callback(...) syntax is pretty gross and unconventional in modern Phabricator.

joshuaspence added a comment.Feb 9 2015, 9:11 PM

Hmm, one issue here is that parameters to call_user_func are not passed by reference.

joshuaspence added a comment.Feb 9 2015, 9:12 PM

As such, maybe a null callback isn't such a bad idea.

I had tried this:

call_user_func($callback, $userdata, $pattern, $pos, $argv[$arg], $len);

But it failed so hard that I couldn't even submit the diff:

I think this works:

call_user_func_array($callback, array($userdata, &$pattern, &$pos, &$value, &$length));

Er, I copied the parameters from the wrong place.

call_user_func_array($callback, array($userdata, &$pattern, &$pos, &$argv[$arg], &$len));

But null would be fine too.

Wouldn't that constitute call-time pass-by-reference? (which is removed in PHP 5.4)

It only counts if the reference is a direct child of a call.

PHP is lol.

I don't follow.

This is call-time pass-by-reference:

f(&$x);

This isn't:

f($y);

...even if the definition of $y is one of these:

$y = &$value;
$y = array(&$value);

Gotcha. Does that mean that my call-time pass-by-reference lint is wrong? :(

epriestley added a comment.Feb 9 2015, 9:22 PM

Another way to put it is that with call-time pass-by-reference, suppose we have:

function f($v) {
  $v++;
}

And then:

$x = 0;

Then, these two statements have different meanings:

f(&$x);      // Call-time pass-by-reference, $x == 1 now. The "&" has transformed f() into a by-ref function.
f($y = &$x); // This is *not* call-time pass-by-reference, $x == 0.

Or I could be making that up, I never used this feature even when it was en vogue.

Technically, yes. I think. Pretty sure. But honestly I'd probably just do the null thing at this point given how much this snowballed out of control into PHP land.

what a nice, readable implementation

surely this must be a fairly sensible language
