+%%
+%% @doc Metaprogramming in Erlang.
+%% Merl is a more user friendly interface to the `erl_syntax' module, making
+%% it easy both to build new ASTs from scratch and to
+%% match and decompose existing ASTs. For details that are outside the scope
+%% of Merl itself, please see the documentation of {@link erl_syntax}.
+%%
+%% == Quick start ==
+%%
+%% To enable the full power of Merl, your module needs to include the Merl
+%% header file:
+%% ```-include_lib("syntax_tools/include/merl.hrl").'''
+%%
+%% Then, you can use the `?Q(Text)' macros in your code to create ASTs or match
+%% on existing ASTs. For example:
+%% ```Tuple = ?Q("{foo, 42}"),
+%% ?Q("{foo, _@Number}") = Tuple,
+%% Call = ?Q("foo:bar(_@Number)")'''
+%%
+%% Calling `merl:print(Call)' will then print the following code:
+%% ```foo:bar(42)'''
+%%
+%% The `?Q' macros turn the quoted code fragments into ASTs, and lifts
+%% metavariables such as `_@Tuple' and `_@Number' to the level of your Erlang
+%% code, so you can use the corresponding Erlang variables `Tuple' and `Number'
+%% directly. This is the most straightforward way to use Merl, and in many
+%% cases it's all you need.
+%%
+%% You can even write case switches using `?Q' macros as patterns. For example:
+%% ```case AST of
+%% ?Q("{foo, _@Foo}") -> handle(Foo);
+%% ?Q("{bar, _@Bar}") when erl_syntax:is_integer(Bar) -> handle(Bar);
+%% _ -> handle_default()
+%% end'''
+%%
+%% These case switches only allow `?Q(...)' or `_' as clause patterns, and the
+%% guards may contain any expressions, not just Erlang guard expressions.
+%%
+%% If the macro `MERL_NO_TRANSFORM' is defined before the `merl.hrl' header
+%% file is included, the parse transform used by Merl will be disabled, and in
+%% that case, the match expressions `?Q(...) = ...', case switches using
+%% `?Q(...)' patterns, and automatic metavariables like `_@Tuple' cannot be
+%% used in your code, but the Merl macros and functions still work. To do
+%% metavariable substitution, you need to use the `?Q(Text, Map)' macro, e.g.:
+%% ```Tuple = ?Q("{foo, _@bar, _@baz}", [{bar, Bar}, {baz,Baz}])'''
+%%
+%% The text given to a `?Q(Text)' macro can be either a single string, or a
+%% list of strings. The latter is useful when you need to split a long
+%% expression over multiple lines, e.g.:
+%% ```?Q(["case _@Expr of",
+%% " {foo, X} -> f(X);",
+%% " {bar, X} -> g(X)",
+%% " _ -> h(X)"
+%% "end"])'''
+%% If there is a syntax error somewhere in the text (like the missing semicolon
+%% in the second clause above) this allows Merl to generate an error message
+%% pointing to the exact line in your source code. (Just remember to
+%% comma-separate the strings in the list, otherwise Erlang will concatenate
+%% the string fragments as if they were a single string.)
+%%
+%% == Metavariable syntax ==
+%%
+%% There are several ways to write a metavariable in your quoted code:
+%% <ul>
+%% <li>Atoms starting with `@', for example `` '@foo' '' or `` '@Foo' ''</li>
+%% <li>Variables starting with `_@', for example `_@bar' or `_@Bar'</li>
+%% <li>Strings starting with ``"'@'', for example ``"'@File"''</li>
+%% <li>Integers starting with 909, for example `9091' or `909123'</li>
+%% </ul>
+%% Following the prefix, one or more `_' or `0' characters may be used to
+%% indicate "lifting" of the variable one or more levels, and after that, a `@'
+%% or `9' character indicates a glob metavariable (matching zero or more
+%% elements in a sequence) rather than a normal metavariable. For example:
+%% <ul>
+%% <li>`` '@_foo' '' is lifted one level, and `_@__foo' is lifted two
+%% levels</li>
+%% <li>`_@@@@bar' is a glob variable, and `_@_@bar' is a lifted glob
+%% variable</li>
+%% <li>`90901' is a lifted variable,`90991' is a glob variable, and `9090091'
+%% is a glob variable lifted two levels</li>
+%% </ul>
+%% (Note that the last character in the name is never considered to be a lift
+%% or glob marker, hence, `_@__' and `90900' are only lifted one level, not
+%% two. Also note that globs only matter for matching; when doing
+%% substitutions, a non-glob variable can be used to inject a sequence of
+%% elements, and vice versa.)
+%%
+%% If the name after the prefix and any lift and glob markers is `_' or `0',
+%% the variable is treated as an anonymous catch-all pattern in matches. For
+%% example, `_@_', `_@@@@_', `_@__', or even `_@__@_'.
+%%
+%% Finally, if the name without any prefixes or lift/glob markers begins with
+%% an uppercase character, as in `_@Foo' or `_@_@Foo', it will become a
+%% variable on the Erlang level, and can be used to easily deconstruct and
+%% construct syntax trees:
+%% ```case Input of
+%% ?Q("{foo, _@Number}") -> ?Q("foo:bar(_@Number)");
+%% ...'''
+%% We refer to these as "automatic metavariables". If in addition the name ends
+%% with `@', as in `_@Foo@', the value of the variable as an Erlang term will
+%% be automatically converted to the corresponding abstract syntax tree when
+%% used to construct a larger tree. For example, in:
+%% ```Bar = {bar, 42},
+%% Foo = ?Q("{foo, _@Bar@@}")'''
+%% (where Bar is just some term, not a syntax tree) the result `Foo' will be a
+%% syntax tree representing `{foo, {bar, 42}}'. This avoids the need for
+%% temporary variables in order to inject data, as in
+%% ```TmpBar = erl_syntax:abstract(Bar),
+%% Foo = ?Q("{foo, _@TmpBar}")'''
+%%
+%% If the context requires an integer rather than a variable, an atom, or a
+%% string, you cannot use the uppercase convention to mark an automatic
+%% metavariable. Instead, if the integer (without the `909'-prefix and
+%% lift/glob markers) ends in a `9', the integer will become an Erlang-level
+%% variable prefixed with `Q', and if it ends with `99' it will also be
+%% automatically abstracted. For example, the following will increment the
+%% arity of the exported function f:
+%% ```case Form of
+%% ?Q("-export([f/90919]).") ->
+%% Q2 = erl_syntax:concrete(Q1) + 1,
+%% ?Q("-export([f/909299]).");
+%% ...'''
+%%
+%% == When to use the various forms of metavariables ==
+%%
+%% Merl can only parse a fragment of text if it follows the basic syntactical
+%% rules of Erlang. In most places, a normal Erlang variable can be used as
+%% metavariable, for example:
+%% ```?Q("f(_@Arg)") = Expr'''
+%% but if you want to match on something like the name of a function, you have
+%% to use an atom as metavariable:
+%% ```?Q("'@Name'() -> _@@@@_." = Function'''
+%% (note the anonymous glob variable `_@@@@_' to ignore the function body).
+%%
+%% In some contexts, only a string or an integer is allowed. For example, the
+%% directive `-file(Name, Line)' requires that `Name' is a string literal and
+%% `Line' an integer literal:
+%%
+%% ```?Q("-file(\"'@File\", 9090).") = ?Q("-file(\"foo.erl\", 42).")).'''
+%% This will extract the string literal `"foo.erl"' into the variable `Foo'.
+%% Note the use of the anonymous variable `9090' to ignore the line number. To
+%% match and also bind a metavariable that must be an integer literal, we can
+%% use the convention of ending the integer with a 9, turning it into a
+%% Q-prefixed variable on the Erlang level (see the previous section).
+%%
+%% === Globs ===
+%%
+%% Whenever you want to match out a number of elements in a sequence (zero or
+%% more) rather than a fixed set of elements, you need to use a glob. For
+%% example:
+%% ```?Q("{_@@@@Elements}") = ?Q({a, b, c})'''
+%% will bind Elements to the list of individual syntax trees representing the
+%% atoms `a', `b', and `c'. This can also be used with static prefix and suffix
+%% elements in the sequence. For example:
+%% ```?Q("{a, b, _@@@@Elements}") = ?Q({a, b, c, d})'''
+%% will bind Elements to the list of the `c' and `d' subtrees, and
+%% ```?Q("{_@@@@Elements, c, d}") = ?Q({a, b, c, d})'''
+%% will bind Elements to the list of the `a' and `b' subtrees. You can even use
+%% plain metavariables in the prefix or suffix:
+%% ```?Q("{_@First, _@@@@Rest}") = ?Q({a, b, c})'''
+%% or
+%% ```?Q("{_@@@@_, _@Last}") = ?Q({a, b, c})'''
+%% (ignoring all but the last element). You cannot however have two globs as
+%% part of the same sequence.
+%%
+%% === Lifted metavariables ===
+%%
+%% In some cases, the Erlang syntax rules make it impossible to place a
+%% metavariable directly where you would like it. For example, you cannot
+%% write:
+%% ```?Q("-export([_@@@@Name]).")'''
+%% to match out all name/arity pairs in the export list, or to insert a list of
+%% exports in a declaration, because the Erlang parser only allows elements on
+%% the form `A/I' (where `A' is an atom and `I' an integer) in the export list.
+%% A variable like the above is not allowed, but neither is a single atom or
+%% integer, so `` '@@@@Name' '' or `909919' wouldn't work either.
+%%
+%% What you have to do in such cases is to write your metavariable in a
+%% syntactically valid position, and use lifting markers to denote where it
+%% should really apply, as in:
+%% ```?Q("-export(['@@_@@Name'/0]).")'''
+%% This causes the variable to be lifted (after parsing) to the next higher
+%% level in the syntax tree, replacing that entire subtree. In this case, the
+%% `` '@@_@@Name'/0 '' will be replaced with `` '@@@@Name' '', and the ``/0''
+%% part was just used as dummy notation and will be discarded.
+%%
+%% You may even need to apply lifting more than once. To match the entire
+%% export list as a single syntax tree, you can write:
+%% ```?Q("-export(['@@__Name'/0]).")'''
+%% using two underscores, but with no glob marker this time. This will make the
+%% entire ``['@@__Name'/0]'' part be replaced with `` '@@Name' ''.
+%%
+%% Sometimes, the tree structure of a code fragment isn't very obvious, and
+%% parts of the structure may be invisible when printed as source code. For
+%% instance, a simple function definition like the following:
+%% ```zero() -> 0.'''
+%% consists of the name (the atom `zero'), and a list of clauses containing the
+%% single clause `() -> 0'. The clause consists of an argument list (empty), a
+%% guard (empty), and a body (which is always a list of expressions) containing
+%% the single expression `0'. This means that to match out the name and the
+%% list of clauses of any function, you'll need to use a pattern like
+%% ``?Q("'@Name'() -> _@_@Body.")'', using a dummy clause whose body is a glob
+%% lifted one level.
+%%
+%% To visualize the structure of a syntax tree, you can use the function
+%% `merl:show(T)', which prints a summary. For example, entering
+%% ```merl:show(merl:quote("inc(X, Y) when Y > 0 -> X + Y."))'''
+%% in the Erlang shell will print the following (where the `+' signs separate
+%% groups of subtrees on the same level):
+%% ```function: inc(X, Y) when ... -> X + Y.
+%% atom: inc
+%% +
+%% clause: (X, Y) when ... -> X + Y
+%% variable: X
+%% variable: Y
+%% +
+%% disjunction: Y > 0
+%% conjunction: Y > 0
+%% infix_expr: Y > 0
+%% variable: Y
+%% +
+%% operator: >
+%% +
+%% integer: 0
+%% +
+%% infix_expr: X + Y
+%% variable: X
+%% +
+%% operator: +
+%% +
+%% variable: Y'''
+%%
+%% This shows another important non-obvious case: a clause guard, even if it's
+%% as simple as `Y > 0', always consists of a single disjunction of one or more
+%% conjunctions of tests, much like a tuple of tuples. Thus:
+%% <ul>
+%% <li>``"when _@Guard ->"'' will only match a guard with exactly one
+%% test</li>
+%% <li>``"when _@@@@Guard ->"'' will match a guard with one or more
+%% comma-separated tests (but no semicolons), binding `Guard' to the list
+%% of tests</li>
+%% <li>``"when _@_Guard ->"'' will match just like the previous pattern, but
+%% binds `Guard' to the conjunction subtree</li>
+%% <li>``"when _@_@Guard ->"'' will match an arbitrary nonempty guard,
+%% binding `Guard' to the list of conjunction subtrees</li>
+%% <li>``"when _@__Guard ->"'' will match like the previous pattern, but
+%% binds `Guard' to the whole disjunction subtree</li>
+%% <li>and finally, ``"when _@__@Guard ->"'' will match any clause,
+%% binding `Guard' to `[]' if the guard is empty and to `[Disjunction]'
+%% otherwise</li>
+%% </ul>
+%%
+%% Thus, the following pattern matches all possible clauses:
+%% ```"(_@@Args) when _@__@Guard -> _@@Body"'''
