Square bracket in yaml files

[nameer]

Describe the bug

Not coloring closing square bracket in YAML files. The bracket is recognized if there is a space between the word and bracket.

To Reproduce

Scenerio 1

repos:
    - repo: local
      hooks:
          - id: myid
            types: [python]
    - repo: local
      hooks:
          - id: secondid
            types: [file, python]

See the color of [ and ] around texts python and file.

Scenerio 2 Opposed to the above, if there is a space as in here:

repos:
    - repo: local
      hooks:
          - id: myid
            types: [python ]
    - repo: local
      hooks:
          - id: secondid
            types: [file, python ]

it works as expected.

Expected behavior

Same color for both opening and closing square brackets, in both scenarios.

Scenario 2

[luochen1990]

Yes, I can reproduce this issue.

I find that it is because this syntax rule of yaml:

execute 'syn match yamlPlainScalar /'.s:ns_plain_out.'/'
execute 'syn match yamlPlainScalar contained /'.s:ns_plain_in.'/'

And find it in :syntax:

yamlPlainScalar xxx match /\%([^\-?:,[\]{}#&*!|>'"%@`\n\r\uFEFF \t]\|[?:\-]\%([^\n\r\uFEFF \t]\)\@=\)\%([
^\n\r\uFEFF \t]#\|:[^\n\r\uFEFF \t]\|[^\n\r\uFEFF \t:#]\)*/
                   match /\%([^\-?:,[\]{}#&*!|>'"%@`\n\r\uFEFF \t]\|[?:\-]\%([^,[\]{}\n\r\uFEFF \t]\)\@=\
)\%([^\n\r\uFEFF \t]#\|:[^,[\]{}\n\r\uFEFF \t]\|[^,[\]{}\n\r\uFEFF \t:#]\)*/  contained

So, the possible solution might be: option1: add syn clear yamlPlainScalar in the "after" configuration field. option2: disable rainbow for yaml seperately.

Do I understand correctly that the issue is yamlPlainScalar includes the closing square bracket as part of the scalar? Removing yamlPlainScalar isn't great as it loses the highlighting for the scalar itself...
