Allow to ignore special character sequences for cy.type

[WiseBird]

Current behavior:

cy.type considers everything in {} as modifier sequence. In our app we have embedded code runner. For testing we put there code from fixtures with cy.type. And cy.type throws CypressError: Special character sequence: '{...}' is not recognized when code includes some braced expression.

Desired behavior:

Add option to cy.type to not treat {} as modifier sequence.

Versions

Cypress: 3.2.0

@WiseBird You can type {{} to type the literal { key as shown in the docs, so this should work:

cy.get('input')
  .type('{{}mycommand}')
  .should('have.value', '{mycommand}')

Looks a little bit funky, but we had to choose some character, happened to be {

@jennifer-shehane Yes, I can escape them. But as I said we type source code, it can be quite big. You need to go through it and find all lines with both { } and then escape. Replacing all { with {{ wont work as if there is no } cypress will type both characters.

Wouldn't it be much easier to simply say that there is no control sequences?

[jennifer-shehane]

We could probably add an option to type like, 'charSequences: false`. This will be pretty low priority for our team to work on though, since it is possible to achieve what is needed for this to work.

We are always welcome to pull requests.

Sorry for my stupidity. While looking at tests I got how escaping really works.
