Wrong line count for the language Elm (and maybe other languages too) when encounter certain characters

[lucamug]

The following line of Elm code make the counter to stop the count:

    Html.node "style" [] [ Html.text "div[role=button] {-webkit-tap-highlight-color: transparent}" ]

For example, this file 4 lines of code are reported correctly:

module Main exposing (main)

import Html


main =
    Html.node "style" [] [ Html.text "div[role=button] {-webkit-tap-highlight-color: transparent}" ]

But for this file, still 4 lines of code are reported, wrongly.

module Main exposing (main)

import Html


main =
    Html.node "style" [] [ Html.text "div[role=button] {-webkit-tap-highlight-color: transparent}" ]


a =
    3

The culprit seems being {-}, or a similar string where the dash can be followed by any character, like {-xxx}.

Yes, this is an anticipated bug with roots back to SLOCCount, ref the comment block for function remove_haskell_comments() (which is included as an Elm filter) beginning at https://github.com/AlDanial/cloc/blob/9b1c380fdad27bcf9e86e5884467167b51873adf/cloc#L7361. It is the {- inside the string that the code doesn't account for. I'll have to add logic to see if comment markers are inside a string.

Take your time. For the moment I just added a space between { and - (that is still valid CSS) 😊

Well, I did take my time :) I reran the original case reported as showing 3 lines instead of 4. cloc 1.98 reports the answer is 4 although I don't recall actively changing anything for Elm since then. Can you try with the latest cloc?
