Hi and thank you for this great tool!
I've been trying httpYac as a way to be able to use *.http files generated in IntelliJ IDEA outside of IntelliJ. However this syntax, which is valid in IntelliJ, is not supported in httpYac (tested with the VSCode plugin):
POST {{API_ROOT}}/users/sign_in
Content-Type: application/x-www-form-urlencoded
email = {{email}} &
password = {{password}}
