# Read the Ruby Hacking Guide chapter 11, available in English at

#
# Remember two things about Ragel scanners:
#
#   1) Longest match wins.
#
#   2) If two matches have the same length, the first
#      in source code wins.
#
# General rules of making Ragel and Bison happy:
#
#  * `p` (position) and `@te` contain the index of the character
#    they're pointing to ("current"), plus one. `@ts` contains the index
#    of the corresponding character. The code for extracting matched token is:
#
#       @source_buffer.slice(@ts...@te)
#
#  * If your input is `foooooooobar` and the rule is:
#
#       'f' 'o'+
#
#    the result will be:
#
#       foooooooobar
#       ^ ts=0   ^ p=te=9
#
#  * A Ragel lexer action should not emit more than one token, unless
#    you know what you are doing.
#
#  * All Ragel commands (fnext, fgoto, ...) end with a semicolon.
#
#  * If an action emits the token and transitions to another state, use
#    these Ragel commands:
#
#       emit($whatever)
#       fnext $next_state; fbreak;
#
#    If you perform `fgoto` in an action which does not emit a token nor
#    rewinds the stream pointer, the parser's side-effectful,
#    context-sensitive lookahead actions will break in a hard to detect
#    and debug way.
#
#  * If an action does not emit a token:
#
#       fgoto $next_state;
#
#  * If an action features lookbehind, i.e. matches characters with the
#    intent of passing them to another action:
#
#       p = @ts - 1
#       fgoto $next_state;
#
#    or, if the lookbehind consists of a single character:
#
#       fhold; fgoto $next_state;
#
#  * Ragel merges actions. So, if you have `e_lparen = '(' %act` and
#    `c_lparen = '('` and a lexer action `e_lparen | c_lparen`, the result
#    _will_ invoke the action `act`.
#
#    e_something stands for "something with **e**mbedded action".
#
#  * EOF is explicit and is matched by `c_eof`. If you want to introspect
#    the state of the lexer, add this rule to the state:
#
#       c_eof => do_eof;
#
#  * If you proceed past EOF, the lexer will complain:
#
#       NoMethodError: undefined method `ord' for nil:NilClass

# {Map} relates AST nodes to the source code they were parsed from.
# More specifically, a {Map} or its subclass contains a set of ranges:
#
#  * `expression`: smallest range which includes all source corresponding
#    to the node and all `expression` ranges of its children.
#  * other ranges (`begin`, `end`, `operator`, ...): node-specific ranges
#    pointing to various interesting tokens corresponding to the node.
#
# Note that the {Map::Heredoc} map is the only one whose `expression` does
# not include other ranges. It only covers the heredoc marker (`<<HERE`),
# not the here document itself.
#
# All ranges except `expression` are defined by {Map} subclasses.
#
# Ranges (except `expression`) can be `nil` if the corresponding token is
# not present in source. For example, a hash may not have opening/closing
# braces, and so would its source map.
#
#     p Parser::CurrentRuby.parse('[1 => 2]').children[0].loc
#     # => <Parser::Source::Map::Collection:0x007f5492b547d8
#     #  @end=nil, @begin=nil,
#     #  @expression=#<Source::Range (string) 1...7>>
#
# The {file:doc/AST_FORMAT.md} document describes how ranges associated to source
# code tokens. For example, the entry
#
#     (array (int 1) (int 2))
#
#     "[1, 2]"
#      ^ begin
#           ^ end
#      ~~~~~~ expression
#
# means that if `node` is an {Parser::AST::Node} `(array (int 1) (int 2))`,
# then `node.loc` responds to `begin`, `end` and `expression`, and
# `node.loc.begin` returns a range pointing at the opening bracket, and so on.
#
# If you want to write code polymorphic by the source map (i.e. accepting
# several subclasses of {Map}), use `respond_to?` instead of `is_a?` to
# check whether the map features the range you need. Concrete {Map}
# subclasses may not be preserved between versions, but their interfaces
# will be kept compatible.
#
# You can visualize the source maps with `ruby-parse -E` command-line tool.

# {Rewriter} is deprecated. Use {TreeRewriter} instead.

# TreeRewriter has simplified semantics, and customizable policies
# with regards to clobbering. Please read the documentation.
#
# Keep in mind:
# - Rewriter was discarding the `end_pos` of the given range for `insert_before`,
#   and the `begin_pos` for `insert_after`. These are meaningful in TreeRewriter.
# - TreeRewriter's wrap/insert_before/insert_after are multiple by default, while
#   Rewriter would raise clobbering errors if the non '_multi' version was called.
# - The TreeRewriter policy closest to Rewriter's behavior is:
#       different_replacements: :raise,
#       swallowed_insertions: :raise,
#       crossing_deletions: :accept

  #
  # Updates which are adjacent to each other, but do not overlap, are also

  #
  # RULES:
  #
  # - Insertion ("replacing" a zero-length range):
  #   - Two insertions at the same point conflict. This is true even
  #     if the earlier insertion has already been merged with an adjacent
  #     update, and even if they are both inserting the same text.
  #   - An insertion never conflicts with a replace or remove operation
  #     on its right or left side, which does not overlap it (in other
  #     words, which does not update BOTH its right and left sides).
  #   - An insertion always conflicts with a remove operation which spans
  #     both its sides.
  #   - An insertion conflicts with a replace operation which spans both its
  #     sides, unless the replacement text is longer than the replaced text
  #     by the size of the insertion (or more), and the portion of
  #     replacement text immediately after the insertion position is
  #     identical to the inserted text.
  #
  # - Removal operations never conflict with each other.
  #
  # - Replacement operations:
  #   - Take the portion of each replacement text which falls within:
  #     - The other operation's replaced region
  #     - The other operation's replacement text, if it extends past the
  #       end of its own replaced region (in other words, if the replacement
  #       text is longer than the text it replaces)
  #   - If and only if the taken texts are identical for both operations,
  #     they do not conflict.

Parser::Source::Rewriter::DEPRECATION_WARNING = T.let(T.unsafe(nil), String)

# {TreeRewriter} performs the heavy lifting in the source rewriting process.
# It schedules code updates to be performed in the correct order.
#
# For simple cases, the resulting source will be obvious.
#
# Examples for more complex cases follow. Assume these examples are acting on
# the source `'puts(:hello, :world)`. The methods #wrap, #remove, etc.
# receive a Range as first argument; for clarity, examples below use english
# sentences and a string of raw code instead.
#
# ## Overlapping ranges:
#
# Any two rewriting actions on overlapping ranges will fail and raise
# a `ClobberingError`, unless they are both deletions (covered next).
#
# * wrap ':hello, ' with '(' and ')'
# * wrap ', :world' with '(' and ')'
#  => CloberringError
#
# ## Overlapping deletions:
#
# * remove ':hello, '
# * remove ', :world'
#
# The overlapping ranges are merged and `':hello, :world'` will be removed.
# This policy can be changed. `:crossing_deletions` defaults to `:accept`
# but can be set to `:warn` or `:raise`.
#
# ## Multiple actions at the same end points:
#
# Results will always be independent on the order they were given.
# Exception: rewriting actions done on exactly the same range (covered next).
#
# Example:
# * replace ', ' by ' => '
# * wrap ':hello, :world' with '{' and '}'
# * replace ':world' with ':everybody'
# * wrap ':world' with '[', ']'
#
# The resulting string will be `'puts({:hello => [:everybody]})'`
# and this result is independent on the order the instructions were given in.
#
# Note that if the two "replace" were given as a single replacement of ', :world'
# for ' => :everybody', the result would be a `ClobberingError` because of the wrap
# in square brackets.
#
# ## Multiple wraps on same range:
# * wrap ':hello' with '(' and ')'
# * wrap ':hello' with '[' and ']'
#
# The wraps are combined in order given and results would be `'puts([(:hello)], :world)'`.
#
# ## Multiple replacements on same range:
# * replace ':hello' by ':hi', then
# * replace ':hello' by ':hey'
#
# The replacements are made in the order given, so the latter replacement
# supersedes the former and ':hello' will be replaced by ':hey'.
#
# This policy can be changed. `:different_replacements` defaults to `:accept`
# but can be set to `:warn` or `:raise`.
#
# ## Swallowed insertions:
# wrap 'world' by '__', '__'
# replace ':hello, :world' with ':hi'
#
# A containing replacement will swallow the contained rewriting actions
# and `':hello, :world'` will be replaced by `':hi'`.
#
# This policy can be changed for swallowed insertions. `:swallowed_insertions`
# defaults to `:accept` but can be set to `:warn` or `:raise`
#
# ## Implementation
# The updates are organized in a tree, according to the ranges they act on
# (where children are strictly contained by their parent), hence the name.

# {Parser::TreeRewriter} offers a basic API that makes it easy to rewrite
# existing ASTs. It's built on top of {Parser::AST::Processor} and
# {Parser::Source::TreeRewriter}
#
# For example, assume you want to remove `do` tokens from a while statement.
# You can do this as following:
#
#     require 'parser/current'
#
#     class RemoveDo < Parser::TreeRewriter
#       def on_while(node)
#         # Check if the statement starts with "do"
#         if node.location.begin.is?('do')
#           remove(node.location.begin)
#         end
#       end
#     end
#
#     code = <<-EOF
#     while true do
#       puts 'hello'
#     end
#     EOF
#
#     ast           = Parser::CurrentRuby.parse code
#     buffer        = Parser::Source::Buffer.new('(example)', source: code)
#     rewriter      = RemoveDo.new
#
#     # Rewrite the AST, returns a String with the new form.
#     puts rewriter.rewrite(buffer, ast)
#
# This would result in the following Ruby code:
#
#     while true
#       puts 'hello'
#     end
#
# Keep in mind that {Parser::TreeRewriter} does not take care of indentation when
# inserting/replacing code so you'll have to do this yourself.
