Format function |
Fri, Jun 14 2013 11:43 AM | Permanent Link |
Christian Kaufmann | Hi,
I have this function from Delphi. Since EWB only supports "%s", I have to rewrite the method. Any suggestions how to do it? I found this: https://code.google.com/p/jsxt/source/browse/trunk/js/String.js But I don't know, if it is possible, to integrate that as "External Code" in EWB. cu Christian function BSSwimTimeToStr(ASwimTime: Integer; AShowNT: Boolean): String; var h,m,s,d : Integer; begin if (ASwimTime >= 1) and (ASwimTime < 2147483647) then begin h := ASwimTime div 3600000; m := (ASwimTime mod 3600000) div 60000; s := (ASwimTime mod 60000) div 1000; d := (ASwimTime mod 1000) div 10; if h > 0 then Result := Format('%d:%.2d:%.2d.%.2d', [h, m, s, d]) else if m > 0 then Result := Format('%d:%.2d.%.2d', [m, s, d]) else Result := Format('%d.%.2d', [s, d]); end else if AShowNT then Result := 'NT' else Result := ''; end; |

Christian Kaufmann | I just found some more JS samples for Format():
http://stackoverflow.com/questions/610406/javascript-equivalent-to-printf-string-format There is one, that looks quite "compact" and complete to me: String.form = function(str, arr) { var i = -1; function callback(exp, p0, p1, p2, p3, p4) { if (exp=='%%') return '%'; if (arr[++i]===undefined) return undefined; var exp = p2 ? parseInt(p2.substr(1)) : undefined; var base = p3 ? parseInt(p3.substr(1)) : undefined; var val; switch (p4) { case 's': val = arr[i]; break; case 'c': val = arr[i][0]; break; case 'f': val = parseFloat(arr[i]).toFixed(exp); break; case 'p': val = parseFloat(arr[i]).toPrecision(exp); break; case 'e': val = parseFloat(arr[i]).toExponential(exp); break; case 'x': val = parseInt(arr[i]).toString(base?base:16); break; case 'd': val = parseFloat(parseInt(arr[i], base?base:10).toPrecision(exp)).toFixed(0); break; } val = typeof(val)=='object' ? JSON.stringify(val) : val.toString(base); var sz = parseInt(p1); /* padding size */ var ch = p1 && p1[0]=='0' ? '0' : ' '; /* isnull? */ while (val.length<sz) val = p0 !== undefined ? val+ch : ch+val; /* isminus? */ return val; } var regex = /%(-)?(0?[0-9]+)?([.][0-9]+)?([#][0-9]+)?([scfpexd])/g; return str.replace(regex, callback); } String.prototype.$ = function() { return String.form(this, Array.prototype.slice.call(arguments)); } Here are a few examples: String.format("%s %s", [ "This is a string", 11 ])) console.out("%s %s".$("This is a string", 11)) var arr = [ "12.3", 13.6 ]; console.out("Array: %s".$(arr)); var obj = { test:"test", id:12 }; console.out("Object: %s".$(obj)); console.out("%c", "Test"); console.out("%5d".$(12)); // ' 12' console.out("%05d".$(12)); // '00012' console.out("%-5d".$(12)); // '12 ' console.out("%5.2d".$(123)); // ' 120' console.out("%5.2f".$(1.1)); // ' 1.10' console.out("%10.2e".$(1.1)); // ' 1.10e+0' console.out("%5.3p".$(1.12345)); // ' 1.12' console.out("%5x".$(45054)); // ' affe' console.out("%20#2x".$("45054")); // ' 1010111111111110' console.out("%6#2d".$("111")); // ' 7' console.out("%6#16d".$("affe")); // ' 4505' cu Christian |

<< I have this function from Delphi. Since EWB only supports "%s", I have to rewrite the method. Any suggestions how to do it? >> Look at how the FormatSettings in the WebCore unit uses the TParser for parsing the date/time formats. You'll have to do something similar for the various Format formatting passed in. Tim Young Elevate Software www.elevatesoft.com |
