jsonc comment support

[SebastianJ91]

Hi,

would it be possible to add jsonc support for allowing comments?
jsonc is used in some configuration files like Visual Studio Code.
Maybe also json5 would be an topic of interest.

A mode switch between standard json or extended json-features would be needed.

Thanks for your suggestion. There are many JSON dialects. Adding support for them is not on the roadmap any time soon.

Hi
ACE editor supports JSON5, Is there any plan to support it?

[josdejong]

I've no plans to spend time on that anytime soon myself. If anyone is interested in implementing it we can discuss the details to see if it is feasible (it's an open source project), but I expect it will be a lot of work.

JSONC with """ multiline strings (a must!)

UPDATE: We needed multiline strings """like in Python""". Comments was also useful...but:

Changing the JSON spec is useless if the VS Code syntax highlighting extension doesn't support it.

We finally realized that JSON is not designed for human readability, so we switched to YAML.

But then, YAML didn’t work well with tabs, so we had to create this yaml/pyyaml#804.

In the end, I was deeply disappointed with the world. IMO, a tab is a tab and not some sequence of spaces.

@kripper I've used YAML too but found it hard to use in practice. There are more alternatives though, like JSON5, did you have a look into that?

Here two articles I wrote about JSON alternatives:

• https://jsoneditoronline.org/indepth/compare/json-alternatives-for-configuration-files/
• https://jsoneditoronline.org/indepth/compare/json-alternatives-for-data/

[kripper]

did you have a look into that?

Yes, but there was no decent multiline string support:
json5/json5#52

Use case: have a json with prompt templates. You don't want to change your text line by line to copy/paste into a chatbox textbox input to test.

[josdejong]

Ah, I understand. So then I guess you could maybe use TOML or JavaScript. Anyway, I suppose you've tried them all 😅.

[kripper]

Yes. YAML and TOML are the options.
