| 7 | * ctx->name and ctx->value) for each name=value pair encountered, | ||
| 8 | * or false when there's nothing further to parse. The current | ||
| 9 | * section name is tracked as ctx->section and lines that aren't | ||
| 10 | * actionable by the caller (i.e. section/comment/blank/invalid | ||
| 11 | * lines) are skipped over without returning anything. | ||
| 12 | * | ||
| 13 | * Note that "inline" comments are not supported, since the | ||
| 14 | * EditorConfig specification forbids them and that's the only | ||
| 15 | * use case in this codebase (see commit a61b90f630cd6a32). | ||
