Helper functions for usage such as parsing text, added get_text() remove_chars() - done

[kensoh]

for example -

• get_text(source_text, left_marker, right_marker, optional_count)

examples of usage:
source_text = "welcome to the home... welcome to my home... welcome to our home"

without optional_count, function returns first occurrence of text in between "welcome and "home":
get_text(source_text, 'welcome', 'home') returns "to the"

without optional_count, function returns n occurrence of text in between "welcome and "home":
get_text(source_text, 'welcome', 'home', 2) returns "to my", which is the 2nd occurrence of text in between "welcome" and "home"

function get_text(source_text, left_marker, right_marker, optional_count) {
	var pos1, pos2 = 0;
	if(optional_count === undefined || optional_count === 1)
   	{
		pos1 = source_text.indexOf(left_marker);
		pos2 = source_text.indexOf(right_marker);
   	} else {
		var i = 1;
		while(i <= optional_count) {
			pos1 = source_text.indexOf(left_marker, pos1+1);
			pos2 = source_text.indexOf(right_marker, pos2+1);
			i++;
		}
	}
	return source_text.slice(pos1 + left_marker.length, pos2).trim();
}

Fyi @ruthtxh not sure of latest JS, but for TagUI's JS, below will make pos1 have no value instead of 0. Now making some change and adding to tagui_header.js

var pos1, pos2 = 0;

another change is the pos2 the search should begin after left marker. otherwise if a right marker happens before left marker will give error results

[kensoh]

This line will also have problem with 'marker ... marker ... marker' because first marker will be skipped

pos1 = source_text.indexOf(left_marker, pos1+1);

Changing function to run for first run before starting while loop if needed

[kensoh]

Fyi @ruthtxh below is updated version. Other than above, also added checks for valid input parameters, and to return '' when any time a match is not found. Also combined lines to reduce from 15 lines to 7 lines. For performance improvement because tagui_header.js will be loaded line by line during generation of the JavaScript code. To be reviewed whether that part can be improved or worth improving by loading and writing tagui_header.js all at one go.

// retrieve text between 2 provided anchors in given text content
function get_text(source_text, left_marker, right_marker, optional_count) {
    if (!source_text || !left_marker || !right_marker) return '';
    var left_position = source_text.indexOf(left_marker); if (left_position == -1) return '';
    var right_position = source_text.indexOf(right_marker, left_position+1); if (right_position == -1) return '';
    if (optional_count > 1) {var occurrence_count = 2; while(occurrence_count <= optional_count) {occurrence_count++;
            left_position = source_text.indexOf(left_marker, right_position+1); if (left_position == -1) return '';
            right_position = source_text.indexOf(right_marker, left_position+1); if (right_position == -1) return '';}}
    return source_text.slice(left_position + left_marker.length, right_position).trim();}

Above commit implements get_text(). Users can download the latest copy of TagUI with this and unzip to overwrite your existing installation (please drag the folders under tagui\src to overwrite your existing installation) - https://github.com/kelaberetiv/TagUI/archive/master.zip

In the next release, this will become part of the packaged zip files.

Reviewing adding another function to remove certain characters in the whole string, \n and \t.

remove_char(get_text(), '\n')

[kensoh]

Above commit implements get_text() and remove_char(). Users can download the latest copy of TagUI with this and unzip to overwrite your existing installation (please drag the folders under tagui\src to overwrite your existing installation) - https://github.com/kelaberetiv/TagUI/archive/master.zip

In the next release, this will become part of the packaged zip files.

PS - note there is issue removing backslash when combined with echo statement, due to language parsing limitations

issue

a = '1\\2'
echo RESULT - `remove_char(a,'\\')`

do this way

a = '1\\2'
b = remove_char(a,'\\')
echo `b`

[kensoh]

Above commit rename function to remove_chars() instead to carry the meaning better since it can take multiple characters.
