Please note; requires previous posted function RepTokenPos
returns sorted list.
SelSortList()

Code: Select all

 FUNCTION SelSortList($string, $sep){
      //    function to sort list using Selection Sort
      //     (there are other sorts but this one is stable and
      //    quick. only drawback for small lists max 50 items)
      //  PLEASE Note uses previous posted function RepTokenPos
	$num=gettoken($string, "count", $sep) ;
	while ($i<=$num -1) {
	$Min=$i;
	$j=$i+1;
  	while ($j<=$num) {
	$res=gettoken( $string, $j, $sep);
	$res1=gettoken( $string, $Min, $sep);
	if( $res < $res1) { $Min=$j}
        $j++;
  	}
  	if( $i UnLikeI $Min) {
	$res=gettoken( $string, $i, $sep);
	$res1=gettoken( $string, $Min, $sep);
	// swap
        $string=RepTokenPos($string, $res, $Min, $sep) ;
        $string=RepTokenPos($string, $res1, $i, $sep);
  	}
        $i++;
	}
        return $string;}
Examples
assuming the functions are saved in <xyscripts>\inc\RepTokenPos.xyi

The same functionality already exists as formatlist().

Code: Select all

 $a="20|19|22|21|22|21|19|20|17|19"; $sp1="|";
 text formatlist($a,'ns');

I haven't studied your algorithm extensively but isn't this one a bit shorter and (naturally) a lot faster?

Code: Select all

function SelSortList($string, $sep="|", $direction="a") {
    $sort = ($direction UnLikeI "d") ? "s" : "r";
    return formatlist($string, $sort, $sep);
}

    $a = "20|19|22|21|22|21|19|20|17|19";

    text SelSortList($a);
$direction = a (ascending), d (descending), if neither a or d -> ascending by default

Sorry for taking so long to answer but very busy at moment.
In response to both your posts, it just shows there's always
more than one way to skin a cat. They both have there uses.
When I wrote the function it was an end to a means.
The speed wasn't top of my list, ease of converting from
other programming languages was.
I knew of "formatlist" but know it can't return which tokens
are moved , which would have been the next stage.
I must admit that I did post to see if it would produce an
idea for further uses.
Further ideas are to work on key=value ways to sort values.
Wether that makes sense, I'm not sure.
Another thread is key=(a,b,c) arrays or even (a,b,c,)as
token in lists.

(associative) arrays is something that should be provided by XY natively (for performance reasons) but this has been wish for ... quite some time :)

A related function which maybe useful. It uses a previous function posted called "RepTokenPos".

Code: Select all

FUNCTION swapkeyvalue($string, $sep, $keyvalsep){
          set $d;
       foreach( $item, $string, $sep){
       $key= gettoken($item, 1, $keyvalsep);
       $value=gettoken($item, 2, $keyvalsep);
        $item=RepTokenPos($item, $key, 2, $keyvalsep) ;
        $item=RepTokenPos($item, $value, 1, $keyvalsep);
       $d="$d$item$sep";
        }
        $string=$d;
       return $string;}
I have a script which uses this function twice, once before a sort then to swap back.
This was ("revealed") to me by an accident / purposeful act, on my part.

If you use this function to swap "key value" to "value key" and then "formatlist" and then swap back, it seems to work.
I did try to sort with max first, using "formatlist" "nr" but it did not work, tried to alter my sort function but not clever enough. Maybe someone can come up with complete answer to this problem.
I am hopeful that this function can be useful.

1. Please use proper formatting for your scripts (e.g. indentation). Terrible to read...
2. When you need help with scripting provide at least one example (with "real" data) where something goes wrong
a.) Show what the function accepts as valid input data
b.) Show the expected output

How I would create a key / value swapper function:

Code: Select all

    $str = "Dog:Frank;Cat:Steven;;Building:House";
    text SwapKeyValue($str, ";", ":");

    function SwapKeyValue($pairs, $sep, $keyvalsep) {
        $result = "";
        foreach($pair, $pairs, $sep) {
            $val = gettoken($pair, 1, $keyvalsep);
            $key = gettoken($pair, 2, $keyvalsep);
            $result = $result . $key . (($pair != "") ? $keyvalsep : "") . $val . $sep;
        }
        return trim($result, $sep, "R");
    }

Depening on what input data is delivered it isn't perfect (e.g. it would strip more than one separators from the end if you have multiple empty items in your source string. Could easily be countered with a regexreplace but it would need proper escaping of the character to remove...
Empty values inside the string are handled correctly though

varsize()

Code: Select all

varsize($var)
Returns the raw byte count of a variable's value.
    $var    The variable to measure.


FUNCTION CODE

Code: Select all

FUNCTION varsize(&$var){
  /* calculate byte size of a variable
  ** $var   the variable to measure */
  $r = gettoken(hexdump($var,,'r'), 'count', ' ');
  return ($r==0)?$r:$r-1;
}
Examples
assuming the function is saved in <xyscripts>\inc\varsize.xyi

Code: Select all

INCLUDE 'inc\varsize.xyi'
"varsize() test"
  $a = '0';
  echo varsize($a);
  $d = readfile(<xyini>);
  echo varsize($d);
  echo varsize(readfile(<xyini>,'b'));
Notes
There's a subraction of 1 from the return, because hexdump returns non-empty hex values with a space at the end, adding 1 to the token count found with gettoken.

A simple debug function...

Atm it's tailored to my system because I create the .log file
in a ram disk (don't want to write to an SSD all the time).

I'm using it with Sublime Text. Feel free to change it to
your favorite editor.

$repeat repeats $sep <x> times to delimit debug entries in the file
$sep can be set to e.g. "," if necessary
$repeat is set to 2 by default to make the output more readable

I use an "_Initialize" section that includes this function and starts debugging:

Code: Select all

"_Initialize"
    include_once "<xyscripts>\inc\debug.xyi";
    debug(, "b");
And depending on what I need to debug and how to output it:
E.g. In a foreach loop I would use a $repeat value of 1 to make it more readable

Code: Select all

    $tabs = "R:\Debug|T:\Install";
    foreach($tab, $tabs) {
        $index = gettokenindex(regexreplace($tab, "(#|\[)", "[$1]"), get("Tabs", <crlf>), <crlf>, "iw");
        if ($index) { tab("close", 0, $index); }
        debug("Closed tab with index: $index", , 1)
    }

Code: Select all

function debug($str, $mode="a", $repeat=2, $sep="<crlf>") {
    $editor    = "D:\Tools\Sublime Text\sublime_text.exe";
    $debugFile = "R:\~XYDebug.log";

    if (exists("R:\") != 2) { echo "Ramdrive 'R:\' does not exist, no logging possible!"; }

    if !(regexmatches($mode, "^(b|begin|a|append|e|end)$")) {
        $message = <<<>>>
            ERROR: The debug function knows only three modes:

            01. b[egin]
            02. a[ppend] -> Default
            03. e[nd]

            But it received: "$mode" instead!
>>>;
        echo formatlist($message, "t", <crlf>);
        end 1==1;
    }

    // Start mode
    if (regexmatches($mode, "^(b|begin)$")) {
        $message = "Start of debug log:";
        $time    = formatdate();
        $div     = strrepeat("=", strlen($message) + strlen($time) + 1);
        $header  = <<<>>>
            $message $time
            $div<crlf 2>
>>>;
        writefile($debugFile, <crlf> . regexreplace($header, "^[ \t]+") . , "o", "tu");

    // Append mode
    } elseif (regexmatches($mode, "^(a|append)$")) {
        writefile($debugFile, $str . strrepeat($sep, $repeat), "a", "tu");

    // Stop mode
    } elseif (regexmatches($mode, "^(e|end)$")) {
        run """$editor"" ""$debugFile""", <xypath>;
    }
    return;
}

Like Array.filter() in many languages which creates a new array with all elements that pass the test.

Example: Remove non-existent recent locations from list

Code: Select all

echo listFilter(get("list_recentlocations"), 'exists("{@Item}")', <crlf>)

Code: Select all

/**
 * List Filter
 *
 *
 * @param {list} $list              list of tokens
 * @param {expression} $filter      expression which returns {bool} on evaluation
 *                                  placeholder: {@Item}
 * @param {string} [$separator='|'] list separator
 * @param {flag} $flag              + s : escape single quote (') for each item
 *
 * @return {list} filtered list of tokens
 */
function listFilter($list, $filter, $separator = '|', $flag = '') {
	$l = ;
	foreach($item, $list, $separator) {
		if (strpos($flag, 's') >= 0) {
			$item = replace($item, "'", "''");
		}
		$expr = replace($filter, '{@Item}', $item, 1);
		if (eval($expr)) {
			$l = $l . $item . $separator;
		}
	}
	return trim($l, $separator, 'R');
}
