This series is based on en/sparse-checkout-set. It updates custom tab completion for the sparse-checkout command. Specifically, it corrects the following issues with the current method:
1. git sparse-checkout <TAB> results in an incomplete list of subcommands
(it is missing reapply and add).
2. Options for subcommands are not tab-completable.
3. git sparse-checkout set <TAB> and git sparse-checkout add <TAB> show
both file names and directory names. While this is the desired behavior
for non-cone mode, we want to only show directories in cone mode.The first commit in this series is a set of tests that highlight each of the above issues. The next commit updates the _git_sparse_checkout method in git-completion.bash to enable previously-failing tests to pass. The final commit modifies the original implementation (which recursively printed prospective directories for completion) to only print directories at the current level for improved performance.
Changes since V3 ================
* Update commit descriptions to begin with completion instead of sparse-checkout. * Remove explicit completion of --help, as this is inconsistent with the rest of the completion script. * Use __gitcomp_builtin to auto-complete subcommand options (and remove option completion test from previous iterations, as it is no longer necessary). * Use __git_complete_index_file helper function in place of __gitcomp "$(git ls-tree -d -r HEAD --name-only). * If in cone-mode sparse checkout, only show directory completions. If in non-cone mode sparse checkout show both files and directories.
Changes since V2 ================
* Change use of $prev to $subcommand in _git_sparse_checkout() method in git-completion.bash. * State explicitly that directory completion applies in both cone and non-cone mode in 'sparse-checkout: custom tab completion' commit * Add new patch with __gitcomp_directories method to improve performance by only outputting directories at the current level.
Changes since V1 ================
* Rebase onto en/sparse-checkout-set. * Add subcommand options (including --no-cone) for set and reapply. * Extend 'sparse-checkout completes subcommand options' test to validate new set/reapply subcommand options. * No longer set index.sparse to false in 'sparse-checkout completes directory names' test.
Thanks, Lessley
