# though I walk through the valley of the shadow
# of PHP, I will fear no feature creep, for Crockford and Eich...

# Captures with the ^BS suffix are included for interoperability with themes
# that target Babel Sublime or JS Next. This is not always possible to achieve
# since there are cases where one would always clobber the other. In some cases
# you will see "^BS, adapted" or "^BS, partial", indicating scopes which may not
# lead to 1:1 exact coloring between themes but will nonetheless appear
# harmonious. "-BS" indicates cases where it would not be good to include these
# fallback scopes for various reasons, though they won’t cause any real coloring
# problems; in fact some are improvments where we’ve disambiguated a previous
# conflation. Captures with no ‘BS’ annotations either correspond directly
# already to, or are more specific versions of, scopes from BS & JSNext.

# EXPRESSION ###################################################################

    # to which we would like to give a unique scope when possible. However to be
    # safe we still need to continue on to the usual AE context.
    #
    # Also note that there are problems with the current spec’s grammar
    # definition. Allowing an assignment expression before a method definition
    # creates ambiguities that even a real parser wouldn’t like, muchless a
    # linear regex syntax def. To deal with this we actually need to add to add
    # a kindof hackish lookahead in assignment expression to (hopefully) pop on
    # generator definitions. We can also try to deal with some computed props.

  # AE is what we generally think of when we say ‘expression’. Since we always
  # must arrive at expressions from the ‘statement level’, it’s worth noting
  # that there are only three types of expressions demanded there:
  #
  # - expression
  # - assignment expression
  # - left hand side expression
  #
  # For our purposes, though, the last one must be ignored; there’s just no
  # practical way -- nor any real benefit re: highlighting -- to ensuring that a
  # given expression is in fact an LHSE. And this is just one of many ways that
  # assigning scopes within expressions is far more permissive than the rigid
  # approach used for statements (which generally have nice clear structures and
  # keywords and delimiting punctuation that we want to scope).
  #
  # This context is a greedy consumer. That is, while it requires that there be
  # at least one valid assignment expression, it continues trying to match
  # expression components for as long as possible before popping, since one AE
  # is often be a composition of what could be multiple AEs.
  #
  # Many of the contexts here are only groupings used in includes for clarity
  # and convenience rather than states that one would transition to. However the
  # match sequence is important.
  #
  # Finally note that there are two versions: one which allows the in operator
  # and one which does not. The latter is required for distinguishing the
  # operator from the control keyword in for loops. Though it leads to an
  # especially perverse amount of duplication, I consider this too important to
  # not do.

# STYLED JSX EXTENSIONS ########################################################
#
# Styled JSX is tricky for us to provide nice highlighting for — there are
# practical limits and we have to keep things fairly simple. I originally tried
# delegating to the CSS syntax definition, but this doesn’t work so great
# because in typical usage, one will be embedding expressions in Styled JSX
# strings for style-related constants — numeric values, colors, etc. Each time
# we exited and returned to the CSS literal portions, it’s starting from a blank
# slate, so the CSS highlighting ends up fairly unpredictable.
#
# Since there’s no constraint on what might be interpolated — it could be
# values or portions of values, rule names, selectors, or any arbitrary chunk —
# and because the nature of what is included thusly is opaque to us, our best
# bet is to spin off very simple CSS highlighting rules that provide a few
# basics without having contextual awareness. In other words, we restrict the
# matches to very fuzzy heuristics for lexical tokens. It’s enough to improve
# the usage experience while avoiding stuff that could potentially lead to bad
# highlighting, but it’s decidedly unsophisticated.

# TAGGED TEMPLATE STRING LITERAL SYNTAX EXTENSIONS #############################
#
# Each embedded syntax requires its own set of 2 contexts. The first one simply
# provides a meta scope for the breadth of the template literal so that we can
# highlight it properly (e.g., with a different background-color / font-style).
# This gets pushed to the stack before the 'OPEN' context and immediately pops
# when that context ends (triggered by template-ending punctuation lookahead).
#
# The 'OPEN' context matches the template-starting punctuation and then
# pushes the nested syntax, injecting our own rules that match the enclosing
# template string by using `with_prototype`. When an interpolation sequence is
# found, our agnostic context 'ELEMENT' is pushed to the stack, behind the usual
# 'expression' context. The 'ELEMENT' context is necessary becuase rather than
# using `set` the way 'templateString_ELEMENT' does, it needs to pop so that the
# parent syntax scope remains in the stack.
#
# The following contexts are general helper contexts for any of the syntax-
# specific contexts:
