The printf() function is implemented in fairly standard Phix hll code in builtins\VM\pprntfN.e<br>
Recent-ish additions along the lines of the task description include:<br>
%q, %Q (print with quotes)<br>
%v, %V (apply sprint internally)<br>
%a, %A (print in bases 2..62)<br>
%[i]<i>specifier</i> (print i'th arg here)<br>
%=<i>specifier</i> (centre, with odd padding as eg 3:4)<br>
%|<i>specifier</i> (centre, with odd padding as eg 4:3)<br>
Just as an example, so we can have some actual code here, but omitting the setup of
"centre" from the format string, the latter two were mainly implemented as follows:

<!--</lang>-->
At the same time, similar changes were made to the version of printf() defined in pwa/p2js.js:
<lang javascript>
let padlen = parseInt(size,10)-res.length;
let half = Math.floor(padlen/2);
case '=': res = pad.repeat(half) + res + pad.repeat(padlen-half); break;
case '|': res = pad.repeat(padlen-half) + res + pad.repeat(half); break;
</lang>
