Aya End Of Verse Symbol in SwiftUI [duplicate] - swiftui

I'm working on android application and I'm trying to write arabic number inside arabic end of ayah symbol (۝) into textview.
I've tried to write the end of ayah symbol then the arabic number without any space but it didn't work. I'm using uthmani font.
I want to display it like this picture:
This is part of the code
NumberFormat nf = NumberFormat.getInstance(Locale.forLanguageTag("AR"));
temp+=" "+"\u06DD"+String.valueOf(nf.format(count))+" ";
"\u06DD" is the encoding of (۝) in java.
The result became like this:

You can use font named me_quran with these unicodes U+FD3E + numbers + U+FD3F
﴿ ORNATE RIGHT PARENTHESIS Unicode: U+FD3F, UTF-8: EF B4 BF
﴾ ORNATE LEFT PARENTHESIS Unicode: U+FD3E, UTF-8: EF B4 BE
You can download the font file from here
Example of usage:

Try something like this ﴾١٩٦﴿ which looks like ﴾١٩٦﴿

I just reversed the format and it worked
NumberFormat nf = NumberFormat.getInstance(Locale.forLanguageTag("AR"));
textView.setText(String.valueOf(nf.format(285))+"\u06DD");
(font was roboto)

In Flutter, you can use quran package. getVerseEndSymbol(int verseNumber) function will return aya end symbol with the given verse number.
Example:
Text(
quran.getVerse(18, index + 1) + getVerseEndSymbol(index + 1),
textAlign: TextAlign.right,
),
This will return the symbol with the given verse number.

If you are using uthmanic font "KFGQPC Uthmanic Script HAFS Regular", you just enter a number in arabic like this "٤٤" and it will be rendered as end verse symbol with the number:

for swift use this code for quran aya ending code addition:
let arabicAyaStyle = "\u{FD3F}" + "\(getArabicDigitFor(value:verseObj.verseId))" + "\u{FD3E}"
append arabicAyaStyle to end of any aya text.
func getArabicDigitFor(value:Int) -> String
{
let numberToConvert = NSNumber(value: value)
let formatter = NumberFormatter()
let arLocale = Locale(identifier: "ar")
formatter.locale = arLocale
return formatter.string(from: numberToConvert)!
}

You can use ReplacementSpan to alter how the aya number is rendered
for example this is how I did it
public class EndOfAyaSpan extends ReplacementSpan
{
public RoundedBackgroundSpan(Context context)
{
super();
}
#Override
public void draw(Canvas canvas, CharSequence text, int start, int end, float x, int top, int y, int bottom, Paint paint)
{
float textSize = paint.getTextSize();
canvas.drawText("\u06dd ", 0, 1, x - textSize / 5, (float) y, paint);
paint.setTextSize(textSize - textSize / 3);
canvas.drawText(text, start, end, x, y - textSize / 5, paint);
paint.setTextSize(textSize);
}
#Override
public int getSize(Paint paint, CharSequence text, int start, int end, Paint.FontMetricsInt fm)
{
return Math.round(paint.measureText(text, start, end));
}
}

How to right align text in ImGui Columns?

Suppose I create a table with the following:
ImGui::Columns(3);
ImGui::Text("Header 1");
ImGui::NextColumn();
ImGui::Text("Header 2");
ImGui::NextColumn();
ImGui::Text("Header 3");
ImGui::NextColumn();
ImGui::Text("1");
ImGui::NextColumn();
ImGui::Text("2");
ImGui::NextColumn();
ImGui::Text("3");
ImGui::NextColumn();
ImGui::Columns(1);
How can I get the text in the second row (1, 2, and 3) to be right aligned in the column? I've seen CalcItemWidth and CalcTextSize, but I can't figure out how they work within a multi-column line.
I received help in the ImGui Discord channel and came up with this solution:
ImGui::NextColumn();
std::string text = "1";
ImGui::SetCursorPosX(ImGui::GetCursorPosX() + ImGui::GetColumnWidth() - ImGui::CalcTextSize(text.c_str()).x
- ImGui::GetScrollX() - 2 * ImGui::GetStyle().ItemSpacing.x);
ImGui::Text("%s", text);
Edit: #FabriceMollo's answer is better.
Nearly same code than iHowell answer but new x position should be checked against current position value in order to be well window-border aligned (text will then be right-clipped).
In code:
ImGui::NextColumn();
std::string text = "1";
auto posX = (ImGui::GetCursorPosX() + ImGui::GetColumnWidth() - ImGui::CalcTextSize(text.c_str()).x
- ImGui::GetScrollX() - 2 * ImGui::GetStyle().ItemSpacing.x);
if(posX > ImGui::GetCursorPosX())
ImGui::SetCursorPosX(posX);
ImGui::Text("%s", text);
i think this is better
int your_column = 0;
std::string text = "ID";
auto column1_x = (ImGui::GetCursorPosX() + ImGui::GetColumnWidth(your_column) * 0.5 - ImGui::CalcTextSize(text.c_str()).x);
if (column1_x > ImGui::GetCursorPosX())
ImGui::SetCursorPosX(column1_x);
ImGui::Text("%s", text.c_str());

JavaFX - TextField with regex for zipcode

for my programm I want to use a TextField where the user can enter a zipcode (German ones). For that I tried what you can see below. If the user enters more than 5 digits every additional digit shall be deleted immediately. Of course letters are not allowed.
When I use this pattern ^[0-9]{0,5}$ on https://regex101.com/ it does what I intended to, but when I try this in JavaFX it doesn't work. But I couldn't find a solution yet.
Can anyone tell me what I did wrong?
Edit: For people, who didn't work with JavaFX yet: When the user enters just one character, the method check(String text) is called. So the result should also be true, when there are 1 to 5 digits. But not more ;-)
public class NumberTextField extends TextField{
ErrorLabel label;
NumberTextField(String text, ErrorLabel label){
setText(text);
setFont(Font.font("Calibri", 17));
setMinHeight(35);
setMinWidth(200);
setMaxWidth(200);
this.label = label;
}
NumberTextField(){}
#Override
public void replaceText(int start, int end, String text){
if(check(text)) {
super.replaceText(start, end, text);
}
}
#Override
public void replaceSelection(String text){
if(check(text)){
super.replaceSelection(text);
}
}
private boolean check(String text){
if(text.matches("^[0-9]{0,5}$")){
label.setText("Success");
label.setBlack();
return true;
} else{
return false;
}
}
You don't need to extend TextField to do this. In fact I recommend using a TextFormatter, since this is simpler to implement:
It does not require you to overwrite multiple method. You simply need to decide based on the data about the desired input, if you want to allow the change or not.
final Pattern pattern = Pattern.compile("\\d{0,5}");
TextFormatter<?> formatter = new TextFormatter<>(change -> {
if (pattern.matcher(change.getControlNewText()).matches()) {
// todo: remove error message/markup
return change; // allow this change to happen
} else {
// todo: add error message/markup
return null; // prevent change
}
});
TextField textField = new TextField();
textField.setTextFormatter(formatter);
Your original expression should be working fine, if we wish to validate a five-digits zip though, we might want to drop the 0 quantifier:
^[0-9]{5}$
^\d{5}$
For validation purposes, we might want to keep the start and end anchors, however for just testing, we can remove and see:
[0-9]{5}
\d{5}
It is likely that some other chars, would get through our inputs, which we do not wish to have.
Demo
Test
import java.util.regex.Matcher;
import java.util.regex.Pattern;
final String regex = "^[0-9]{5}$";
final String string = "01234\n"
+ "012345\n"
+ "0\n"
+ "1234";
final Pattern pattern = Pattern.compile(regex, Pattern.MULTILINE);
final Matcher matcher = pattern.matcher(string);
while (matcher.find()) {
System.out.println("Full match: " + matcher.group(0));
for (int i = 1; i <= matcher.groupCount(); i++) {
System.out.println("Group " + i + ": " + matcher.group(i));
}
}

Parsing tags in string

I'm trying to parse a string with custom tags like this
[color value=0x000000]This house is [wave][color value=0xFF0000]haunted[/color][/wave].
I've heard about ghosts [shake]screaming[/shake] here after midnight.[/color]
I've figured out what regexps to use
/\[color value=(.*?)\](.*?)\[\/color\]/gs
/\[wave\](.*?)\[\/wave\]/gs
/\[shake\](.*?)\[\/shake\]/gs
But the thing is - I need to get correct ranges (startIndex, endIndex) of those groups in result string so I could apply them correctly. And that's where I feel completely lost, because everytime I replace tags there's always a chance for indexes to mess up. It gets espesically hard for nested tags.
So input is a string
[color value=0x000000]This house is [wave][color value=0xFF0000]haunted[/color][/wave].
I've heard about ghosts [shake]screaming[/shake] here after midnight.[/color]
And in output I want to get something like
Apply color 0x000000 from 0 to 75
Apply wave from 14 to 20
Apply color 0xFF0000 from 14 to 20
Apply shake from 46 to 51
Notice that's indices match to result string.
How do I parse it?
Unfortunately, I'm not familiar with ActionScript, but this C# code shows one solution using regular expressions. Rather than match specific tags, I used a regular expression that can match any tag. And instead of trying to make a regular expression that matches the whole start and end tag including the text in between (which I think is impossible with nested tags), I made the regular expression just match a start OR end tag, then did some extra processing to match up the start and end tags and remove them from the string keeping the essential information.
using System;
using System.Collections.Generic;
using System.Text.RegularExpressions;
class Program
{
static void Main(string[] args)
{
string data = "[color value=0x000000]This house is [wave][color value=0xFF0000]haunted[/color][/wave]. " +
"I've heard about ghosts [shake]screaming[/shake] here after midnight.[/color]";
ParsedData result = ParseData(data);
foreach (TagInfo t in result.tags)
{
if (string.IsNullOrEmpty(t.attributeName))
{
Console.WriteLine("Apply {0} from {1} to {2}", t.name, t.start, t.start + t.length - 1);
}
else
{
Console.WriteLine("Apply {0} {1}={2} from {3} to {4}", t.name, t.attributeName, t.attributeValue, t.start, t.start + t.length - 1);
}
Console.WriteLine(result.data);
Console.WriteLine("{0}{1}\n", new string(' ', t.start), new string('-', t.length));
}
}
static ParsedData ParseData(string data)
{
List<TagInfo> tagList = new List<TagInfo>();
Regex reTag = new Regex(#"\[(\w+)(\s+(\w+)\s*=\s*([^\]]+))?\]|\[(\/\w+)\]");
Match m = reTag.Match(data);
// Phase 1 - Collect all the start and end tags, noting their position in the original data string
while (m.Success)
{
if (m.Groups[1].Success) // Matched a start tag
{
tagList.Add(new TagInfo()
{
name = m.Groups[1].Value,
attributeName = m.Groups[3].Value,
attributeValue = m.Groups[4].Value,
tagLength = m.Groups[0].Length,
start = m.Groups[0].Index
});
}
else if (m.Groups[5].Success)
{
tagList.Add(new TagInfo()
{
name = m.Groups[5].Value,
tagLength = m.Groups[0].Length,
start = m.Groups[0].Index
});
}
m = m.NextMatch();
}
// Phase 2 - match end tags to start tags
List<TagInfo> unmatched = new List<TagInfo>();
foreach (TagInfo t in tagList)
{
if (t.name.StartsWith("/"))
{
for (int i = unmatched.Count - 1; i >= 0; i--)
{
if (unmatched[i].name == t.name.Substring(1))
{
t.otherEnd = unmatched[i];
unmatched[i].otherEnd = t;
unmatched.Remove(unmatched[i]);
break;
}
}
}
else
{
unmatched.Add(t);
}
}
int subtractLength = 0;
// Phase 3 - Remove tags from the string, updating start positions and calculating length in the process
foreach (TagInfo t in tagList.ToArray())
{
t.start -= subtractLength;
// If this is an end tag, calculate the length for the corresponding start tag,
// and remove the end tag from the tag list.
if (t.otherEnd.start < t.start)
{
t.otherEnd.length = t.start - t.otherEnd.start;
tagList.Remove(t);
}
// Keep track of how many characters in tags have been removed from the string so far
subtractLength += t.tagLength;
}
return new ParsedData()
{
data = reTag.Replace(data, string.Empty),
tags = tagList.ToArray()
};
}
class TagInfo
{
public int start;
public int length;
public int tagLength;
public string name;
public string attributeName;
public string attributeValue;
public TagInfo otherEnd;
}
class ParsedData
{
public string data;
public TagInfo[] tags;
}
}
The output is:
Apply color value=0x000000 from 0 to 76
This house is haunted. I've heard about ghosts screaming here after midnight.
-----------------------------------------------------------------------------
Apply wave from 14 to 20
This house is haunted. I've heard about ghosts screaming here after midnight.
-------
Apply color value=0xFF0000 from 14 to 20
This house is haunted. I've heard about ghosts screaming here after midnight.
-------
Apply shake from 47 to 55
This house is haunted. I've heard about ghosts screaming here after midnight.
---------
Let me show you a parsing method that you can apply not only to the case above, but to every case with a pattern cutting through the case. This method is not limited to the terms - color, wave, shake.
private List<Tuple<string, string>> getVals(string input)
{
List<Tuple<string, string>> finals = new List<Tuple<string,string>>();
// first parser
var mts = Regex.Matches(input, #"\[[^\u005D]+\]");
foreach (var mt in mts)
{
// has no value=
if (!Regex.IsMatch(mt.ToString(), #"(?i)value[\n\r\t\s]*="))
{
// not closing tag
if (!Regex.IsMatch(mt.ToString(), #"^\[[\n\r\t\s]*\/"))
{
try
{
finals.Add(new Tuple<string, string>(Regex.Replace(mt.ToString(), #"^\[|\]$", "").Trim(), ""));
}
catch (Exception es)
{
Console.WriteLine(es.ToString());
}
}
}
// has value=
else
{
try
{
var spls = Regex.Split(mt.ToString(), #"(?i)value[\n\r\t\s]*=");
finals.Add(new Tuple<string, string>(Regex.Replace(spls[0].ToString(), #"^\[", "").Trim(), Regex.Replace(spls[1].ToString(), #"^\]$", "").Trim()));
}
catch (Exception es)
{
Console.WriteLine(es.ToString());
}
}
}
return finals;
}

AS3 and HTML5 - parse string into array using regex

I've been looking and playing with RegEx for a while now and am trying to find this solution that I can apply to both AS3 and to HTML5.
I've got a custom user entry section, 256 chars that they can customize.
What I would like is for them to use my predefined table of codes 00 - 99 and they can insert them into the box to automatically generate a response that can go through a few hundred examples.
Here is a simple example:
Please call: 04
And ask for help for product ID:
03
I'd be able to take this and say, okay i got the following into an array:
[Please call: ]
[04]
[/n]
[And ask for help for product ID: ]
[/n]
[03]
and possibly apply a flag to say whether this is a database entry or not
[Please call: ][false]
[04][true]
[/n][false]
[And ask for help for product ID: ][false]
[/n][false]
[03][true]
this would be something that my program could read. Where I know that for the ## matches, to find a database entry and insert, though for anything else, use the strings.
I have been playing around on
http://gskinner.com/RegExr/
to try and brute force an answer to no avail so far.
Any help would be greatly appreciated.
The best I've come up with so far for matches is the following. Though this is my first time playing with the regex functions and would need to find out how to push these entries into my ordered array.
\d\d
\D+
And would need some way to combine them to pull an array... or I'll be stuck with a crappy loop:
//AS3 example
database_line_item:int = 127;
previous_value_was_int:boolean = false;
_display_text:string = "";
for(var i:int = 0; i < string.length; i++){
if(string.charAt(i) is int){
if(previous_value_was_in){
previous_value_was_int = true;
}else{
_display_text += getDatabaseValue(string.charAt(i-1)+string.charAt(i), database_line_item);
previous_value_was_int = false;
}
}else{
//Hopefully this handles carriage returns, if not, will have to add that in.
_display_text += string.charAt(i);
}
}
// >>>>>>>>> HTML5 Example <<<<<<<<<<<<<
...
and I would cycle through the database_line_item, though for maybe 400 line items, this will be a taxing, to go through that string. Splitting it into smaller arrays would be easier to handle.
Here is the magic reg : /([^0-9\n\r]+)|(\d+)|(\r\n?|\n)/gi
Exemple output :
[Please call: ][false]
[4][true]
[/n][false]
[And ask for help for product ID:][false]
[/n][false]
[3][true]
Exemple code that do the job and put the data into an array :
package
{
import flash.display.Sprite;
public class TestReg extends Sprite
{
public function TestReg()
{
super();
var data : Array = parse("Please call: 04\n"+
"And ask for help for product ID:\n"+
"03");
// Output
for(var i : uint = 0; i < data.length; i += 2)
trace("[" + data[ i ] + "][" + data[ i + 1 ] + "]");
}
private var _search : RegExp = /([^0-9\n\r]+)|(\d+)|(\r\n?|\n)/gi;
public function parse(str : String) : Array
{
var result : Array = [];
var data : Array = str.match( _search );
for each(var item : * in data)
{
// Replace new line by /n
if(item.charAt( 0 ) == "\n" || item.charAt( 0 ) == "\r")
item = "/n";
// Convert to int if is a number
if( ! isNaN( parseFloat( item.charAt( 0 ) ) ) )
item = parseInt( item );
result.push( item );
result.push( !( item is String ));
}
return result;
}
}
}

Restrict TextField to act like a numeric stepper

I am making a numeric stepper from scratch, so I want my text field to only accept numbers in this format: xx.x, x.x, x, or xx where x is a number. For example:
Acceptable numbers:
1
22
15.5
3.5
None Acceptable numbers:
213
33.15
4332
1.65
Maybe this will help some how:
http://livedocs.adobe.com/flash/9.0/ActionScriptLangRefV3/flash/text/TextField.html#restrict
This is what I got so far:
var tx:TextField = new TextField();
tx.restrict="0-9."; //Maybe there is a regular expression string for this?
tx.type=TextFieldType.INPUT;
tx.border=true;
You can copy past this in flash and it should work.
Thank you very much for your help good sirs.
Very similar to TheDarklins answer, but a little more elegant. And actually renders _tf.restrict obsolete, but I would still recommend using it.
_tf.addEventListener(TextEvent.TEXT_INPUT, _onTextInput_validate);
Both of these event listeners here do the EXACT same function identically. One is written in a one line for those who like smaller code. The other is for those who like to see what's going on line by line.
private function _onTextInput_validate(__e:TextEvent):void
{
if ( !/^\d{1,2}(?:\.(?:\d)?)?$/.test(TextField(__e.currentTarget).text.substring(0, TextField(__e.currentTarget).selectionBeginIndex) + __e.text + TextField(__e.currentTarget).text.substring(TextField(__e.currentTarget).selectionEndIndex)) ) __e.preventDefault();
}
for a more broken down version of the event listener
private function _onTextInput_validate(__e:TextEvent):void
{
var __reg:RegExp;
var __tf:TextField;
var __text:String;
// set the textfield thats causing the event.
__tf = TextField(__e.currentTarget);
// Set the regular expression.
__reg = new RegExp("\\d{1,2}(?:\\.(?:\\d)?)?$");
// or depending on how you like to write it.
__reg = /^\d{1,2}(?:\.(?:\d)?)?$/;
// Set all text before the selection.
__text = __tf.text.substring(0, __tf.selectionBeginIndex);
// Set the text entered.
__text += __e.text;
// Set the text After the selection, since the entered text will replace any selected text that may be entered
__text += __tf.text.substring(__tf.selectionEndIndex);
// If test fails, prevent default
if ( !__reg.test(__text) )
{
__e.preventDefault();
}
}
I have had to allow xx. as a valid response otherwise you would need to type 123 then go back a space and type . for 12.3. That is JUST NOT NICE. So 12. is now technically valid.
package
{
import flash.display.Sprite;

import flash.events.TextEvent;
public class DecimalPlaces extends Sprite
{
public function DecimalPlaces()
{
var tf:TextField = new TextField();
tf.type = TextFieldType.INPUT;
tf.border = true;

tf.x = tf.y = 20;
tf.restrict = ".0-9"
tf.addEventListener(TextEvent.TEXT_INPUT, restrictDecimalPlaces);
addChild(tf);
}
function restrictDecimalPlaces(evt:TextEvent):void
{
var matches:Array = evt.currentTarget.text.match(/\./g);
var allowedDecimalPlaces:uint = 1;
if ((evt.text == "." && matches.length >= 1) ||
(matches.length == 1 && (evt.currentTarget.text.lastIndexOf(".") + allowedDecimalPlaces < evt.currentTarget.text.length)))
evt.preventDefault();
}
