I made a mistake merge. Reverting it inc778945806undid the state on master, but now I realize it crippled the git merge mechanism. As the merge contained a mix of commits from `master..staging-next` and other commits from `staging-next..staging`, it got the `staging-next` branch into a state that was difficult to recover. I reconstructed the "desired" state of staging-next tree by: - checking out the last commit of the problematic range:4effe769e2- `git rebase -i --preserve-merges a8a018ddc0` - dropping the mistaken merge commit and its revert from that range (while keeping reapplication from4effe769e2) - merging the last unaffected staging-next commit (803ca85c20) - fortunately no other commits have been pushed to staging-next yet - applying a diff on staging-next to get it into that state

# installShellCompletion [--cmd <name>] ([--bash|--fish|--zsh] [--name <name>] <path>)...
|

#
|
|
# Each path is installed into the appropriate directory for shell completions for the given shell.
|
|
# If one of `--bash`, `--fish`, or `--zsh` is given the path is assumed to belong to that shell.
|
|
# Otherwise the file extension will be examined to pick a shell. If the shell is unknown a warning
|
|
# will be logged and the command will return a non-zero status code after processing any remaining
|
|
# paths. Any of the shell flags will affect all subsequent paths (unless another shell flag is
|
|
# given).
|
|
#
|
|
# If the shell completion needs to be renamed before installing the optional `--name <name>` flag
|
|
# may be given. Any name provided with this flag only applies to the next path.
|
|
#
|
|
# If all shell completions need to be renamed before installing the optional `--cmd <name>` flag
|
|
# may be given. This will synthesize a name for each file, unless overridden with an explicit
|
|
# `--name` flag. For example, `--cmd foobar` will synthesize the name `_foobar` for zsh and
|
|
# `foobar.bash` for bash.
|
|
#
|
|
# For zsh completions, if the `--name` flag is not given, the path will be automatically renamed
|
|
# such that `foobar.zsh` becomes `_foobar`.
|
|
#
|
|
# A path may be a named fd, such as produced by the bash construct `<(cmd)`. When using a named fd,
|
|
# the shell type flag must be provided, and either the `--name` or `--cmd` flag must be provided.
|
|
# This might look something like:
|
|
#
|
|
# installShellCompletion --zsh --name _foobar <($out/bin/foobar --zsh-completion)
|
|
#
|
|
# This command accepts multiple shell flags in conjunction with multiple paths if you wish to
|
|
# install them all in one command:
|
|
#
|
|
# installShellCompletion share/completions/foobar.{bash,fish} --zsh share/completions/_foobar
|
|
#
|
|
# However it may be easier to read if each shell is split into its own invocation, especially when
|
|
# renaming is involved:
|
|
#
|
|
# installShellCompletion --bash --name foobar.bash share/completions.bash
|
|
# installShellCompletion --fish --name foobar.fish share/completions.fish
|
|
# installShellCompletion --zsh --name _foobar share/completions.zsh
|
|
#
|
|
# Or to use shell newline escaping to split a single invocation across multiple lines:
|
|
#
|
|
# installShellCompletion --cmd foobar \
|
|
# --bash <($out/bin/foobar --bash-completion) \
|
|
# --fish <($out/bin/foobar --fish-completion) \
|
|
# --zsh <($out/bin/foobar --zsh-completion)
|
|
#
|
|
# If any argument is `--` the remaining arguments will be treated as paths.
