+function _bash_completion_spack {
+ # In all following examples, let the cursor be denoted by brackets, i.e. []
+
+ # For our purposes, flags should not affect tab completion. For instance,
+ # `spack install []` and `spack -d install --jobs 8 []` should both give the same
+ # possible completions. Therefore, we need to ignore any flags in COMP_WORDS.

+ # For example, `spack -d install []` will call _spack_install
+ # and `spack compiler add []` will call _spack_compiler_add
+ local subfunction=$(IFS='_'; echo "_${COMP_WORDS_NO_FLAGS[*]}")
+
+ # However, the word containing the current cursor position needs to be
+ # added regardless of whether or not it is a flag. This allows us to
+ # complete something like `spack install --keep-st[]`
+ COMP_WORDS_NO_FLAGS+=("${COMP_WORDS[$COMP_CWORD]}")
+
+ # Since we have removed all words after COMP_CWORD, we can safely assume
+ # that COMP_CWORD_NO_FLAGS is simply the index of the last element
+ local COMP_CWORD_NO_FLAGS=$(( ${#COMP_WORDS_NO_FLAGS[@]} - 1 ))
+
+ # There is no guarantee that the cursor is at the end of the command line
+ # when tab completion is envoked. For example, in the following situation:
+ # `spack -d [] install`
+ # if the user presses the TAB key, a list of valid flags should be listed.
+ # Note that we cannot simply ignore everything after the cursor. In the
+ # previous scenario, the user should expect to see a list of flags, but
+ # not of other subcommands. Obviously, `spack -d list install` would be
+ # invalid syntax. To accomplish this, we use the variable list_options

+
+ # In general, when envoking tab completion, the user is not expecting to
+ # see optional flags mixed in with subcommands or package names. Tab
+ # completion is used by those who are either lazy or just bad at spelling.
+ # If someone doesn't remember what flag to use, seeing single letter flags
+ # in their results won't help them, and they should instead consult the
+ # documentation. However, if the user explicitly declares that they are
+ # looking for a flag, we can certainly help them out.
+ # `spack install -[]`
+ # and
+ # `spack install --[]`

+ # subcommand has no non-flag completions, such as `spack arch []`, it
