String containing consecutive uppercase letters

[ren510dev]

Prepare a structure like this:

type AddressInformation struct {
    ID            int       `json:"id"`
    VirtualIPv4   string    `json:"virtual_ipv4"`
    VirtualIPv6   string    `json:"virtual_ipv6"`
    IsVirtualIPv6 bool      `json:"is_virtual_ipv6"`
    MacAddress    string    `json:"mac_address"`
}

golangci-lint prints an error like this:

Error: ${ROOT_DIR}/address_information.go:14:26: [golangci] json(snake): got 'virtual_ipv4' want 'virtual_i_pv4' (tagliatelle)
Error: ${ROOT_DIR}/address_information.go:15:26: [golangci] json(snake): got 'virtual_ipv6' want 'virtual_i_pv6' (tagliatelle)
Error: ${ROOT_DIR}/address_information.go:16:26: [golangci] json(snake): got 'is_virtual_ipv6' want 'is_virtual_i_pv6' (tagliatelle)

The desired snake case is "virtual_ipv4" in this case.

However, as you can see, tagliatelle is requesting to separate the "i" and "p" as "virtual_i_pv4".

In this case, it is desirable to output as "virtual_ipv4".

Or is "IPv4" "Ipv4" ?!

Hello,

It's related to the lib that I use to create the expected case: https://github.com/ettle/strcase

Related to #2

There is a PR on strcase (ettle/strcase#13) about this topic but it doesn't fix the problem with all cases (ex: VirtualIPv4 in kebab or snake case result in virtual-i-pv4 or virtual_i_pv4).

But I added an option (ignored-fields) to ignore fields https://github.com/ldez/tagliatelle?tab=readme-ov-file#as-a-golangci-lint-linter

Note for future me:

Currently, the string is cut:

• on each uppercase letter: FooBar -> Foo + Bar
• on non-letter foo bar or foo_bar, etc.: -> foo + bar
• and some number formatting is kept version2.3 -> version + 2.3

The problem occurs with special cases: plurals, "version", ?

• fooUUIDbar vs fooUUIDs
• fooIPbar vs fooIPv4
