Link to specific columns within lines

[1ec5]

GitHub’s new code viewing UI supports an alternative URL format for permalinking to specific columns within a line. For example:

https://github.com/maplibre/maplibre-native/blob/749458d6c866223c4966b0c6734b8d5cd8ad9744/platform/ios/platform/darwin/test/MLNExpressionTests.mm#LL1168C81-L1171C50

links to the range from line 1168, column 81 to line 1171, column 50.

The Open in GitHub service should use this format to reflect the more specific selection in Xcode.
