If I put string literal with escaped double quote \" it will cause panic.

[Keats]

Tera actually doesn't support escaped quotes currently.

However it supports several type of strings so your example can be written {{'hangar new --name test_app --author "Will Smoth <will_s@example.com>" --database sqlite --database-url=test_app.sqlite cd test_app' }}.

However (bis), this is currently broken on 0.11.5 but I've fixed it yesterday so it should be part of 0.11.6 to be released this weekend.

Another question is that parsing that template should give an error, not a panic. Is your code using unwrap somewhere?

[karuna]

Hi @Keats , using single quote works, but it show different result than double quote

The single quote showing and double quote missing.

I'm using rocket so I think the panic is because somewhere in the rocket's code. I'll debug and maybe fix the problem there

[Keats]

That error is the "However (bis)" in my previous message, you can try the current master branch and it should work

[Keats]

I just published 0.11.6 which should fix the bug you had above

[karuna]

It works with single quote. Thank you
