Customize special characters

[m-matsubara]

I would like to implement a special character customization feature.

I would like to discuss the spec before creating a pull request.

I'm thinking of creating something like the following as a property, what do you think?

published properties

• SpecialChars: TSynSpecialChars
  • TabGlyph: WideChar
  • TabAlign: TSynSpecialCharsAlign // (sscaLeading, sscaCenter, sscaTrailing)
  • LineBreakGlyph: WideChar
  • SpaceGlyph: WideChar
  • IdepgraphicSpaceGlyph: WideChar // White space characters often used in Japanese texts.

Also, I think this is a unique requirement for Japan, but I would like to be able to customize Idepgraphic space as a special character independently. Is it okay to include this specification?

I was looking at the code base to see if this was supportable the other week (I don't think it is at the moment). I receive text files that sometimes contain control or extended characters and wondered if they can be shown similar to Notepad++ and VS Code with little glyths.

@DGH2112 Please open a different issue on how control characters appear without the eoShowSpecialChars option, showing examples of how they appear in SynEdit and how the appear in VS Code.

I have opened an issue. See #87.
@m-matsubara @DGH2112 @MShark67 what do you think?

[pyscripter]

@DGH2112 This is now committed. Could you please try it and report whether it comes close to what you wanted?

@m-matsubara
What is the motivation for your proposal. Is it

• to be able to customize the shown special symbols?
• or just to show a different symbol for the ideographic space?

Also what are the Tabalign characters?

@pyscripter
thank you.

I want to customize the Special Characters, especially the line break characters. Currently, in SynEdit, the line break character cannot be changed from ¶ because Special Characters are defined as constants. I would like to customize it to characters such as ↲, ↓, and ←.

TabAlign has wide tabs, so I think it would be nice to be able to change where the glyph is displayed. In my case, I would like to customize the TabGlyph symbol to the left (Leading).

Happy to change the SynLineBreakGlyph. I don't like '¶'. Here is what the U+21B2 looks like:

Should I commit the change?

Also, I could consider the alignment of the tab symbol. In fact VS code also aligns it to the left.

I would prefer that to adding further complexity, about something which is does not affect the normal use of the editor.

[pyscripter]

Committed the change to SynLineBreakGlyph. Also I have made the constants in SynEditTypes variables, so that they can be customized. See b1a00a7.

[m-matsubara]

Thank you.

I agree with that specification.

I still think ↲ is better for line breaks.

in c17d425 I have allowed the customization of the alignment of the tab glyph.
