How to escape {{...}} ?

[gregorylevilain]

I have a query body that includes a "{{fileName}}" which should remain as is. How can I escape it and avoid variable replacement ?
Thanks a lot for your help, and for Bruno :)

This needs to be fixed. We use handlebars for interpolation, and we should allow escaping

This is the line: https://github.com/usebruno/bruno/blob/main/packages/bruno-electron/src/ipc/network/interpolate-string.js#L37

const template = Handlebars.compile(str, { noEscape: true });

@Its-treason @martinsefcik @mirkogolze I believe it should be safe to allow escaping. and remove the {noEscape: true }

@helloanoop I don't think setting noEscape: false helps as it is for something different. If your variable contains text which is HTML then it is replaced in template as escaped/not escaped HTML based on this parameter. https://handlebarsjs.com/guide/#html-escaping
So I think noEscape must stay true in Bruno.

I expect @gregorylevilain needs something different. He has {{fileName}} in request body and he wants to send it as {{fileName}} without any replacement applied. Currently it is replaced with empty string in case fileName variable is not defined.

I tried to register the following helper in Handlebars:

Handlebars.registerHelper('helperMissing', (options) => options.fn(this));

based on the documentation https://handlebarsjs.com/guide/hooks.html#helpermissing and some googling

and now if you have in request body {{fileName}} and fileName variable is not defined then it is not touched and printed as {{fileName}}.

If fileName variable is defined then it is replaced with variable value.

I think the same behavior is in Postman.

Sounds like a good solution and would close #1056
