[PATCH v5 3/3] completion: handle unusual characters for sparse-checkout

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Lessley Dennington <lessleydennington@xxxxxxxxx>

Update the __gitcomp_directories method to de-quote and handle unusual
characters in directory names. Although this initially involved an attempt
to re-use the logic in __git_index_files, this method removed
subdirectories (e.g. folder1/0/ became folder1/), so instead new custom
logic was placed directly in the __gitcomp_directories method.
