Updates » Texteditor test

Please find attached a modified FastColoredTextBox text editor for CJK characters. The functional changes are very simple but it's a huge change in code.

In current release version and in BETA till v1.1.4.21, the CJK character handling is as follows:
Measure each character's width if it exceeds the predefined fixed character width of the current font. If the width of the character is bigger, scale down the character width and hight by a calculated factor. After that, the CJK character fits into the fixed grid and uses the place that other normal characters use. That leads to character representation with different character size. It also leads in very poor performance in Chinese and Japanese K-IDE versions.

The attached DLL changes that to the following strategy:
Instead of meassuring each character, CJK characters are identified by the character code. When a CJK character is identified, the character is expected to have a double width compared to normal characters. When drawing such characters, the space for that characters are doubled. This strategy must be kept in mind, when placing the caret with the cursor keys or the mouse and when selecting a number of characters.

If you like to test the new editor component, please replace your existing FastColoredTextBox.dll file with the attached one (after unpacking). Please keep the original dll file to revert it if the editor will do unexpected things! The changes are only relevant for people who are using CJK characters, but it effects all character sets and languages.

As always: feel free to download, install and test the new editor and leave your comments! - Thank you!

Thanks for your job, it works fine. I'll keep giving the feedback.

Hello, I'm back with 5 issues:

1. Can't identify full-width and half-width in Japanese(Full-width character takes up 2 bypes, half-width is 1 byte), so half-width takes more space.

2. Character is missing in Texteditor when enter Chinese comments.

(Before is K-IDE, another is Visual Studio Code)

3. #Future# Hope add options to change encoding.

4. Index out of range serveral times.

Tnak you for your report!

1. I don't understand full-width and half-width character set and meaning. Can you please explain? What is wrong with the text you've shown as "half-width"?

2. Can you send me a sample text to copy&paste? There should be no missing character.

3. If it's necessary I will think about it.

4. I will check in the code. Can you tell me what you did before the exception?

#5 by cquante , Wed Sep 18, 2024 9:25 am

Exception should be resolved now and printing is possible. For the other things I need some test data.

#6 by Zoirkae , Wed Sep 18, 2024 9:31 am

1. I can't add external links because I'm new, but you can search "Half-width kana" on wiki. Half-width shows in Pic01 between each character has one-character-space, it's better to remove it.

2. What I said is not clearly enough, in other texteditors (Pic03) when I type English characters they have candidature rather than real inputting. You can consider that Chinese character is made up of one or multi English characters, this help us make sure the text we enter is right.

3. Yep, it's necessary.

4. Keep K-IDE background sometime and return to interface, then select codes

#7 by cquante , Wed Sep 18, 2024 9:45 am

-> 1.) So half-width kana characters should not be expanded to double size but should kept in a normal character size?

#8 by Zoirkae , Wed Sep 18, 2024 9:52 am

Yep, if it does what you see is "w o r d"

#9 by cquante , Wed Sep 18, 2024 9:58 am

This (should) prevent half-size Katakana from beeing resized.

Ah - sorry! I should not change the version number without recompiling K-IDE.

The latest version Chinese and Japanese look perfect, thanks a lot , BTW can you understand issue 2 now?

Thank you for the report!

Please: if not related to CJK characters and the editor changes for that, post bug reports in the bug section (-> here <-)! Thank you!

I solved the issue, but at the moment I cannot update because of 'work in progress'.

#15 by Zoirkae , Wed Sep 18, 2024 12:39 pm

Got it! if you want more details about issue 2, I’m glad to help you.
