Initialisms with digits in the middle of them aren't recognized

[konatacarneiro]

What happened?

In an application, there's a certain query type called "p2p". During generation, the function name for the query resolver gets converted to pascal case and becomes "P2p" which is undesirable. So I declared the initialism "P2P" in gqlgen.yml to fix this issue, but the initialism seems to be ignored and the expected resolver field name is still "P2p".

What did you expect?

I expected the "P2P" initialism to be applied to the "p2p" query type upon capitalization, yielding the resolver name "P2P", not "P2p".

Minimal graphql.schema and models to reproduce

type P2PModel {
  id: ID!
  text: String!
}

type Query {
  p2p(id: ID!): P2PModel!
}

input NewP2P {
  text: String!
}

type Mutation {
  create_p2p(input: NewP2P!): P2PModel!
}

In gqlgen.yml, include the following:

go_initialisms:
  initialisms:
    - "P2P"

versions

• go run github.com/99designs/gqlgen version: v0.17.49
• go version go1.22.1 linux/amd64

Upon further investigation, the issue seems to lie in this code segment inside codegen/templates/templates.go::wordWalker():

		case unicode.IsLower(runes[i]) && !unicode.IsLower(runes[i+1]):
			// lower->non-lower
			eow = true

The function unicode.IsLower returns true whenever the input rune is a lowercase letter, and returns false for anything else - including digits and special characters. As such, the "2" in "p2p" is treated as the start of a new word, splitting it into "p" and "2p", neither of which match the initialism "P2P".
