Support comments in JSON configuration (aka JSONC) #496
Description
Problem
If my JSON in contains_json contains comments, the parser will fail.
Example:
[".vscode/extensions.json".contains_json]
"unwantedRecommendations" = """
[
// VSCode has implemented an optimized version
"coenraads.bracket-pair-colorizer",
"coenraads.bracket-pair-colorizer-2",
// Lots of conflicts
"esbenp.prettier-vscode",
// Replaced by ESLint
"eg2.tslint",
"ms-vscode.vscode-typescript-tslint-plugin",
// Obsoleted by Pylance
"ms-pyright.pyright",
// Not configurable per workspace, tends to conflict with other linters
// Use eslint-plugin-sonarjs for JS/TS projects
"sonarsource.sonarlint-vscode"
]
"""
"[python]" = """
{
"editor.tabSize": 4,
"editor.rulers": [
72, // PEP8-17 docstrings
// 79, // PEP8-17 default max
// 88, // Black default
99, // PEP8-17 acceptable max
120 // Our hard rule
]
}
"""Results in
".vscode/extensions.json".contains_json.unwantedRecommendations.value: Invalid JSON (json.decoder.JSONDecodeError: Expecting value: line 2 column 5 (char 8))
".vscode/settings.json".contains_json.[python].value: Invalid JSON (json.decoder.JSONDecodeError: Expecting value: line 4 column 11 (char 62))
Possible solution
Support parsing JSON with Comments (aka JSONC)
Note that this is different than #406 . I am not asking for the comments to be kept when using nitpick fix, I just want the parser to at least ignore comments and not fail.
