Hello Abhishek,

I am just checking about the progress of this issue. Let me know if you need my further assistance on this issue.

Thank you for using Infragistics Components.

Hi Abhishek,

If you want to have “on-the-fly” syntax editor, the only option is to use the XamSyntaxEditor and to host it inside ElementHost control. Also the recommended way to create an ENBF file with the grammar definition for your language. Then you will be able to generate a custom language class using the GenerateClass method of the LanguageGenerator method. An alternative method is to also manually define a custom language class (it needs to inherit LanguageBase class).

I have attached a sample with the XamSyntaxEditor inside an ElementHost, with a custom language.

Please let me know if you have any additional questions.

Hi Hristo

Since a Winforms syntax editor does not exist, kindly provide the sample for xamSyntaxEditor.

As I mentioned, we have the list of functions as a list of string and identifiers start with a "[" and end with "]"

We would like to add the symbols programmatically rather than through EBNF file.

I looked up the samples for xamSyntaxEditor, and while there is a custom language with EBNF sample, I couldnt find the programmatic custom language sample.

Best

Abhishek

Hi Hristo

The sample "Custom Language syntax parsing" has a text box where it allows you to type in and has RichTextbox which shows colored syntax on pressing of a button.

A normal syntax editor does this "on-the-fly" - so I need a sample where text is edited straightaway in the richtextbox.

Thanks

Abhishek

Hello ,

1. 1.We actually have such sample in our sample browser . Its name is “Custom Language Syntax Parsing” which works with RichTextBox. See the attachments of this response.
2. 2.String processing is not of the fast operations, so if going to parse all editors simultaneously, probably it will takes some time. I am not exactly sure what kind of comments you want to get here. Maybe since we don’t have SintaxEditor build in in WindowsForms you should  implement your one, in this case it will be faster if you can save the parsed text along with its formatting, in order to avoid its passing again when you load it. also you could implement some mechanism which will parse only the edited text. Here you should know what amount of text is expected to be parsed, and also you should experiment with different approaches. How long it takes for the how text to be parsed and etc.
3. 3.I believe that attached sample answers this questions.
