sora-editor's Issues

I can't find the languages

how to add the languages pleases e.g html, can't find it

Enhance text selection method

Hi,
the method that this editor has isn't good. it's not smooth as well as it is hard to move the cursor and many other issues compared with the default android text selection method. so it would be way better if you use the default text selection method rather than a custom one (if possible). keep in mind that it offers many editing options such as cope, paste, select all, and much more.

Add Html and Css language

Please add Html and Css language

The CodeEditor should auto scroll horizontally when dragging selection/insert handle

Currently, the CodeEditor only scrolls vertically (upward and downward) if the selection handle or insert handle is being moved by the user. The same behaviour should also be implemented when moved horizontally.

When moving the insert handle horizontally to the right, the CodeEditor scrolls. But this behaviour doesn't seem to be implemented for handle moving horizontally to the left.

Horizontal scroll doesn't work when moving the selection handles horizontally (both left and right).

AutoCompleteWindow is shown above the keyboard

The editor should scroll to a position where the AutoCompleteWindow won't cover the keyboard.

CodeEditor.java的drawLineNumbers里，行号右对齐和居中对齐貌似有问题

问题代码：

            switch (mLineNumberAlign) {
                case LEFT:
                    canvas.drawText(Integer.toString(i + 1), offsetX, y, mPaintOther);
                    break;
                case RIGHT:
                    canvas.drawText(Integer.toString(i + 1), offsetX + width, y, mPaintOther);
                    break;
                case CENTER:
                    canvas.drawText(Integer.toString(i + 1), offsetX + width / 2f, y, mPaintOther);
            }

应该可以这样解决（把行号分割线的边距也计算进去）：

            String lineNumber = Integer.toString(i + 1);
            switch (mLineNumberAlign) {
                case LEFT:
                    canvas.drawText(lineNumber, offsetX, y, mPaintOther);
                    break;
                case RIGHT:
                    canvas.drawText(lineNumber, offsetX + width + mDividerMargin, y, mPaintOther);
                    break;
                case CENTER:
                    canvas.drawText(lineNumber, offsetX + (width + mDividerMargin) / 2f, y, mPaintOther);
            }

BTW：下面这两个计算行号宽度的凡是也许是等价的吧？都是以最大行号的宽度作为行号栏的宽。

    private float measureLineNumber() {
        int count = 0;
        int lineCount = getLineCount();
        while (lineCount > 0) {
            count++;
            lineCount /= 10;
        }
        float single = mPaintOther.measureText("0");
        return single * count * 1.01f;
    }

    private float measureLineNumber() {
        return mPaintOther.measureText(String.valueOf(getLineCount()));
    }

Bug when paste a text from the keyboard.

Hi,
i found a bug when i paste a text using my keyboard.
when i type something immediately after pasting a text using the paste option from the keyboard, it duplicate the text that has been pasted. but if i move the cursor to different position and then move it back, it works fine.
can you take a look at it please.
see the video below.
Thanks.

Last typed word becomes invisible on typing a space, comma or dot ( . ).

I added the repo in my project as written in Readme. I had to override the chars() and codePoints() method in com.rose.editor.common.Content class (I had to override it because I got a error saying that I should implement the inherited abstract methods).

All things work fine except when I type a space, comma or a dot ( . )

I'm using AIDE to compile and run the project.

Any help or guidance is appreciated.

[Bug] Edge Effects drawing not correct

when I scrolling down, sometimes the edge effect drawing from top and vice versa, as if everything is inverted

Merge some drawing processes

Also a requirement to merge some rendering processes into drawing text, such as cursor and its handle , and text background to speed up.
Separating these out can cause drawing to have a worse performance.
Draw text without spans can be merge into draw text with spans. And drawTextDirect() does not highlight selected text. This merge can solve it.

Cannot turn off autocompletion on composing

Autocompletion on composing is not disabled for setAutoCompletionOnComposing(false) in CodeEditor.java.

Current line background does not match text position

Current line background and line number does not match text position.
Recently it has been tested out on Huawei P6.
This is caused by the font used to draw line number and the font used to draw text have a different line height.

XML Analyzer/Language

It'd be cool to have a module for XML language too. We can't implement it using the simple way since XML needs tokenizing and analyzing for syntax highlighting, so the simple way is too limited..

如何在编辑器内使用Spannable

Unable to highlight code using lexer

I'm implementing own CodeAnalyzer for Java Language (can't use existing one due to some reasons).

Here is the analyze () method :

			CodePointCharStream stream = CharStreams.fromReader(new StringReader(content.toString()));
			JavaLexer lexer = new JavaLexer(stream);
			Token token = null;
			boolean first = true;
			while(delegate.shouldAnalyze())
			{
				token = lexer.nextToken();
				if(token == null)
					break;
				if(token.getType() == JavaLexer.EOF)
					break;
				switch(token.getType())
				{
					case JavaLexer.WS :
						if(first)
							colors.addNormalIfNull();
						break;
					case JavaLexer.ABSTRACT:
					case JavaLexer.ASSERT:
					case JavaLexer.BREAK:
					case JavaLexer.CASE:
					case JavaLexer.CATCH:
					case JavaLexer.CLASS:
					case JavaLexer.CONST:
					case JavaLexer.CONTINUE:
					case JavaLexer.DEFAULT:
					case JavaLexer.DO:
					case JavaLexer.ELSE:
					case JavaLexer.ENUM:
					case JavaLexer.EXTENDS:
					case JavaLexer.FINAL:
					case JavaLexer.FINALLY:
					case JavaLexer.FOR:
					case JavaLexer.IF:
					case JavaLexer.GOTO:
					case JavaLexer.IMPLEMENTS:
					case JavaLexer.IMPORT:
					case JavaLexer.INSTANCEOF:
					case JavaLexer.INTERFACE:
					case JavaLexer.NATIVE:
					case JavaLexer.NEW:
					case JavaLexer.PACKAGE:
					case JavaLexer.PRIVATE:
					case JavaLexer.PROTECTED:
					case JavaLexer.PUBLIC:
					case JavaLexer.RETURN:
					case JavaLexer.STATIC:
					case JavaLexer.STRICTFP:
					case JavaLexer.SUPER:
					case JavaLexer.SWITCH:
					case JavaLexer.SYNCHRONIZED:
					case JavaLexer.THIS:
					case JavaLexer.THROW:
					case JavaLexer.THROWS:
					case JavaLexer.TRANSIENT:
					case JavaLexer.TRY:
					case JavaLexer.VOID:
					case JavaLexer.VOLATILE:
					case JavaLexer.WHILE:
						colors.addIfNeeded(token.getLine(), token.getCharPositionInLine(), EditorColorScheme.KEYWORD);
						break;
				}
				
				first = false;
			}

But nothing gets highlighted. If I forcibly add colors using color.add(), whole line is being highlighted.

Any suggestions?

Add EdgeEffect for view

Introduce font cache

After observing MT Manager's editor, I found his editor is much quicker than me.
This probably because it has some cache to measure text quickly.
Knowing this, I tested the speed of two ways to measure text. One with cache while another call native method directly.
When measuring a series of long text for several times, cached one is obvious quicker.
As the following images shows.


It is also faster in a single go:

And their results are the same.
So you may use font caches to equip the editor.

Emoji测量不准和不识别\ud83e开头的Emoji

FontCache.java 中的isEmoji方法需要识别0xd83e，measureChar方法测量 一半的Emoji接一个Emoji会测量错误。应该改成
`/*
* 测量文本 0xd83c 0xd83c 0xdd51
* 0 1 2
*/
public float measureText(char[] chars, int start, int end, Paint p){
float width = 0f;
for( int i = start; i < end; i++ ){
char ch = chars [i];
if( isEmoji(ch) && i + 1 < end ){
buffer [0] = ch;
buffer [1] = chars [++i];

			if( i + 1 < end ){
				buffer [2] = chars [++i];
				if( !isEmoji(buffer [1]) || isEmoji(buffer [2]) ){
					//当第2个字符不是Emoji或第3字符是Emoji时,只测量两个字符
					i--;
					width += p.measureText(buffer, 0, 2);
				}
				else{
					width += p.measureText(buffer, 0, 3);
				}
			}
			else{
				width += p.measureText(buffer, 0, 2);
			}
		}
		else{
			width += measureChar(ch, p);
		}
	}
	return width;
}`

setHorizontalScrollBarEnabled(false)及setVerticalScrollBarEnabled(true)设置没效果，无法禁用滚动条

查阅代码，目测是就没用到isVerticalScrollBarEnabled()和isHorizontalScrollBarEnabled()，需要修改drawScrollBars如下：

    private void drawScrollBars(Canvas canvas) {
        if (!mEventHandler.shouldDrawScrollBar()) {
            return;
        }
        if (isVerticalScrollBarEnabled()) {
            mVerticalScrollBar.setEmpty();
            if (getScrollMaxY() > getHeight() / 2) {
                drawScrollBarTrackVertical(canvas);
            }
            if (getScrollMaxY() > getHeight() / 2) {
                drawScrollBarVertical(canvas);
            }
        }
        if (isHorizontalScrollBarEnabled()) {
            mHorizontalScrollBar.setEmpty();
            if (getScrollMaxX() > getWidth() * 3 / 4) {
                drawScrollBarTrackHorizontal(canvas);
            }
            if (getScrollMaxX() > getWidth() * 3 / 4) {
                drawScrollBarHorizontal(canvas);
            }
        }
    }

Add support for symbol pairs

Match symbol pairs automatically on typing.
Such as '{', '(' and more

[Bug] Drawing not printing symbol not correct

Im, found when printing new text with whitespace, new whitespace not draw and eol symbol draw not correct

Refactor and add plugin system

This includes the following tasks:

• Reorganize code structure
• Extract interfaces for text container due to future updates
• Add plugin system
• Make code more neat
• Language Injection

Use incremental lexer to make highlight faster

Usually, a user types text but color for most regions of text is not going to change, unless the user is currently typing a comment.
So run lexer incrementally can make highlight faster than before and improve user experience greatly.
It is also easy to make a lexer made by JFlex to run incrementally.

Add OCaml language

Hello there,
I would like to add support for OCaml language to this editor.
I already have a lexer for this language written in Swift here: https://github.com/GroupeMINASTE/OCaml-iOS/blob/main/OCaml/Models/OCamlLexer.swift
I saw the wiki, I will try to make a PR in coming weeks to implement this language myself.

Is it ok to add single quote '' and double quote "" to Default symbol pairs?
