Only a brief explanation is given here.</p> + <p>These constructs makes it possible to define open types, that + is, values of that type can be of any ASN.1 type. Also, + relationships can be defined between different types and + values, as classes can hold types, values, objects, object + sets, and other classes in their fields. A class can be + defined in ASN.1 as follows:</p> + <pre> +GENERAL-PROCEDURE ::= CLASS { + &Message, + &Reply OPTIONAL, + &Error OPTIONAL, + &id PrintableString UNIQUE +} +WITH SYNTAX { + NEW MESSAGE &Message + [REPLY &Reply] + [ERROR &Error] + ADDRESS &id +} </pre> + <p>An object is an instance of a class.

The object <c>object2</c> has also an + optional field <c>ERROR</c>, which is a type field. The field + <c>ADDRESS</c> is a <c>UNIQUE</c> field. Objects in an object set + must have unique values in their <c>UNIQUE</c> field, as in + <c>GENERAL-PROCEDURES</c>:</p> + <pre> +GENERAL-PROCEDURES GENERAL-PROCEDURE ::= { + object1 | object2} </pre> + <p>You cannot encode a class, object, or object set, only refer to + it when defining other ASN.1 entities. Typically you refer to a + class as well as to object sets by table constraints and component + relation constraints (X.682) in ASN.1 types, as in the following:</p> + <pre> +StartMessage ::= SEQUENCE { + msgId GENERAL-PROCEDURE.&id ({GENERAL-PROCEDURES}), + content GENERAL-PROCEDURE.&Message ({GENERAL-PROCEDURES}{@msgId}), + } </pre> + <p>In type <c>StartMessage</c>, the constraint following field + <c>content</c> tells that in a value of type + <c>StartMessage</c> the value in field <c>content</c> must + come from the same object that is chosen by field <c>msgId</c>.</p> + <p>So, the value + <c>#'StartMessage'{msgId="home",content="Any Printable String"}</c> + is legal to encode as a <c>StartMessage</c> value. However, the value + <c>#'StartMessage'{msgId="remote", content="Some String"}</c> + is illegal as the constraint in <c>StartMessage</c> tells that + when you have chosen a value from a specific object in object + set <c>GENERAL-PROCEDURES</c> in field + <c>msgId</c>, you must choose a value from that same object in + the content field too. In this second case, it is to be + any <c>INTEGER</c> value.</p> + <p><c>StartMessage</c> can in field <c>content</c> be + encoded with a value of any type that an object in object set + <c>GENERAL-PROCEDURES</c> has in its <c>NEW MESSAGE</c> field. + This field refers to a type field + <c>&Message</c> in the class. Field <c>msgId</c> is always + encoded as a <c>PrintableString</c>, as the field refers to a + fixed type in the class.</p> + <p>In practice, object sets are usually declared to be extensible so + that more objects can be added to the set later. Extensibility is + indicated as follows:</p> + <pre> +GENERAL-PROCEDURES GENERAL-PROCEDURE ::= { + object1 | object2, ...} </pre> + <p>When decoding a type that uses an extensible set constraint, + it is always possible that the value in field <c>UNIQUE</c> + is unknown (that is, the type has been encoded with a later + version of the ASN.1 specification). The unencoded data is then + returned wrapped in a tuple as follows:</p> + + <pre> +{asn1_OPENTYPE,Binary}</pre> + + <p>Here <c>Binary</c> is an Erlang binary that contains the encoded + data. (If option <c>legacy_erlang_types</c> has been given, + only the binary is returned.)</p> + </section> + + <section> + <title>Parameterization (X.683)</title> + <p>Parameterization, which is defined in X.683, can be used when + defining types, values, value sets, classes, objects, or object sets. + A part of a definition can be supplied as a parameter. For + example, if a <c>Type</c> is used in a definition with a certain + purpose, you want the type name to express the intention. This + can be done with parameterization.</p> + <p>When many types (or another ASN.1 entity) only differ in some + minor cases, but the structure of the types is similar, only + one general type can be defined and the differences can be supplied + through parameters.</p> + <p>Example of use of parameterization:</p> + <pre> +General{Type} ::= SEQUENCE +{ + number INTEGER, + string Type +} + +T1 ::= General{PrintableString} + +T2 ::= General{BIT STRING}</pre> + <p>An example of a value that can be encoded as type <c>T1</c> is + <c>{12,"hello"}</c>.</p> + <p>Notice that the compiler does not generate encode/decode functions + for parameterized types, only for the instances of the parameterized + types.

The purpose of ASN.1 is to have a platform - and programming language independent notation to express types - using a standardized set of rules for the transformation of - values of a defined type into a stream of bytes. This stream of - bytes can then be sent on any type of communication - channel. This way, two applications written in different - programming languages running on different computers with - different internal representation of data can exchange instances - of structured data types.</p> - </section> - - <section> - <title>Prerequisites</title> - <p>It is assumed that the reader is familiar with the ASN.1 - notation as documented in the standard definition [<cite - id="X.680"></cite>] which is the primary text.

The code-generator then uses the abstract syntax - tree in order to generate code. - </p> - <p>The generated Erlang files will be placed in the current directory or - in the directory specified with the <c>{outdir,Dir}</c> option. - The following shows how the compiler - can be called from the Erlang shell:</p> - <pre> -1><input> asn1ct:compile("People", [ber]).</input> -ok -2> </pre> - - <p>The <c>verbose</c> option can be given to have information - about the generated files printed:</p> - <pre> -2><input> asn1ct:compile("People", [ber,verbose]).</input> -Erlang ASN.1 compiling "People.asn" ---{generated,"People.asn1db"}-- ---{generated,"People.hrl"}-- ---{generated,"People.erl"}-- -ok -3> </pre> - - <p>The ASN.1 module <c>People</c> is now accepted and the - abstract syntax tree is saved in the <c>People.asn1db</c> file; - the generated Erlang code is compiled using the Erlang compiler - and loaded into the Erlang run-time system. Now there is an API - for <c>encode/2</c> and <c>decode/2</c> in the module - <c>People</c>, which is invoked by: <br></br> - <c><![CDATA['People':encode(<Type name>, <Value>)]]></c> - <br></br> - or <br></br> -<c><![CDATA['People':decode(<Type name>, <Value>)]]></c></p> - - <p>Assume there is a network - application which receives instances of the ASN.1 defined - type Person, modifies and sends them back again:</p> - <code type="none"> -receive - {Port,{data,Bytes}} -> - case 'People':decode('Person',Bytes) of - {ok,P} -> - {ok,Answer} = 'People':encode('Person',mk_answer(P)), - Port ! {self(),{command,Answer}}; - {error,Reason} -> - exit({error,Reason}) - end - end, </code> - <p>In the example above, a series of bytes is received from an - external source and the bytes are then decoded into a valid - Erlang term. This was achieved with the call - <c>'People':decode('Person',Bytes)</c> which returned - an Erlang value of the ASN.1 type <c>Person</c>. Then an answer was - constructed and encoded using - <c>'People':encode('Person',Answer)</c> which takes an - instance of a defined ASN.1 type and transforms it to a - binary according to the BER or PER encoding rules. - <br></br> -The encoder and the decoder can also be run from - the shell.</p> - <pre> -2> <input>Rockstar = {'Person',"Some Name",roving,50}.</input> -{'Person',"Some Name",roving,50} -3> <input>{ok,Bin} = 'People':encode('Person',Rockstar).</input> -{ok,<<243,17,19,9,83,111,109,101,32,78,97,109,101,2,1,2, - 2,1,50>>} -4> <input>{ok,Person} = 'People':decode('Person',Bin).</input> -{ok,{'Person',"Some Name",roving,50}} -5> </pre> - </section> - - <section> - <title>Module dependencies</title> - <p>It is common that ASN.1 modules import defined types, values and - other entities from another ASN.1 module.</p> - <p>Earlier versions of the ASN.1 compiler required that modules that - were imported from had to be compiled before the module that - imported. This caused problems when ASN.1 modules had circular - dependencies.</p> - <p>Referenced modules are now parsed when the compiler finds an - entity that is imported. There will not be any code generated for - the referenced module. However, the compiled module rely on - that the referenced modules also will be compiled.</p> - </section> - </section> - - <section> - <title>The Asn1 Application User Interface</title> - <p>The Asn1 application provides two separate user interfaces:</p> - <list type="bulleted"> - <item> - <p>The module <c>asn1ct</c> which provides the compile-time functions - (including the compiler).</p> - </item> - <item> - <p>The module <c>asn1rt_nif</c> which provides the run-time functions - for the ASN.1 decoder for the BER back-end.</p> - </item> - </list> - <p>The reason for the division of the interface into compile-time - and run-time - is that only run-time modules (<c>asn1rt*</c>) need to be loaded in - an embedded system. - </p> - - <section> - <title>Compile-time Functions</title> - <p>The ASN.1 compiler can be invoked directly from the command-line - by means of the <c>erlc</c> program. This is convenient when compiling - many ASN.1 files from the command-line or when using Makefiles. - Here are some examples of how the <c>erlc</c> command can be used to invoke the - ASN.1 compiler:</p> - <pre> -erlc Person.asn -erlc -bper Person.asn -erlc -bber ../Example.asn -erlc -o ../asnfiles -I ../asnfiles -I /usr/local/standards/asn1 Person.asn </pre> - <p>The useful options for the ASN.1 compiler are:</p> - <taglist> - <tag><c>-b[ber | per | uper]</c></tag> - <item> - <p>Choice of encoding rules, if omitted <c>ber</c> is the - default.</p> - </item> - <tag><c>-o OutDirectory</c></tag> - <item> - <p>Where to put the generated files, default is the current - directory.</p> - </item> - <tag><c>-I IncludeDir</c></tag> - <item> - <p>Where to search for <c>.asn1db</c> files and ASN.1 - source specs in order to resolve references to other - modules. This option can be repeated many times if there - are several places to search in. The compiler will always - search the current directory first.</p> - </item> - <tag><c>+der</c></tag> - <item> - <p>DER encoding rule. Only when using <c>-ber</c> option.</p> - </item> - <tag><c>+asn1config</c></tag> - <item> - <p>This functionality works together with the - <c>ber</c> option.

If those trailing bytes are important they - can be returned along with the decoded value by compiling - the ASN.1 specification with the <c>+undec_rest</c> option. - The return value from the decoder will be - <c>{ok,Value,Rest}</c> where <c>Rest</c> is a binary - containing the trailing bytes.</p> - </item> - <tag><c>+'Any Erlc Option'</c></tag> - <item> - <p>You may add any option to the Erlang compiler when - compiling the generated Erlang files.

The main difference - between OCTET STRINGS and the Character strings is that OCTET - STRINGS have no imposed semantics on the bytes delivered.</p> - <p>However, when using for instance the IA5String (which closely - resembles ASCII) the byte 65 (in decimal - notation) <em>means</em> the character 'A'. - </p> - <p>For example, if a defined type is to be a VideotexString and - an octet is received with the unsigned integer value X, then - the octet should be interpreted as specified in the standard - ITU-T T.100,T.101. - </p> - <p>The ASN.1 to Erlang compiler - will not determine the correct interpretation of each BER - (Basic Encoding Rules) string octet value with different - Character strings. Interpretation of octets is the - responsibility of the application. Therefore, from the BER - string point of view, octets appear to be very similar to - character strings and are compiled in the same way. - </p> - <p>It should be noted that when PER (Packed Encoding Rules) is - used, there is a significant difference in the encoding scheme - between OCTET STRINGS and other strings. The constraints - specified for a type are especially important for PER, where - they affect the encoding. - </p> - <p>Here are some examples:</p> - <pre> -Digs ::= NumericString (SIZE(1..3)) -TextFile ::= IA5String (SIZE(0..64000)) </pre> - <p>with corresponding Erlang assignments:</p> - <pre> -DigsVal1 = "456", -DigsVal2 = "123", -TextFileVal1 = "abc...xyz...", -TextFileVal2 = [88,76,55,44,99,121 .......... a lot of characters here ....] </pre> - <p>The Erlang representation for "BMPString" and - "UniversalString" is either a list of ASCII values or a list - of quadruples. The quadruple representation associates to the - Unicode standard representation of characters. The ASCII - characters are all represented by quadruples beginning with - three zeros like {0,0,0,65} for the 'A' character. When - decoding a value for these strings the result is a list of - quadruples, or integers when the value is an ASCII character.</p> - - <p>The following example shows how it works.

The general syntax to assign a value to the component C - of a named ASN.1 type T in Erlang is the record syntax - <c>#'T'{'C'=Value}</c>. - Where <c>Value</c> may be a value of yet another type T2.</p> - <p>For example:</p> - <pre> -EmbeddedExample DEFINITIONS AUTOMATIC TAGS ::= -BEGIN -B ::= SEQUENCE { - a Arr1, - b T } - -Arr1 ::= SET SIZE (5) OF INTEGER (4..9) - -T ::= CHOICE { - x REAL, - y INTEGER, - z OBJECT IDENTIFIER } - END </pre> - <p>The SEQUENCE b can be encoded like this in Erlang:</p> - <pre> -1> 'EmbeddedExample':encode('B', {'B',[4,5,6,7,8],{x,"7.77"}}). -{ok,<<5,56,0,8,3,55,55,55,46,69,45,50>>} </pre> - </section> - </section> - - <section> - <title>Naming of Records in .hrl Files</title> - <p>When an ASN.1 specification is compiled all defined types of - type SET or SEQUENCE will result in a corresponding record in the - generated hrl file. This is because the values for SET/SEQUENCE - as mentioned in sections above are represented as records.</p> - <p>Though there are some special cases of this functionality that - are presented below.</p> - - <section> - <title>Embedded Structured Types</title> - <p>It is also possible in ASN.1 to have components that are themselves - structured types. - For example, it is possible to have:</p> - <pre> -Emb ::= SEQUENCE { - a SEQUENCE OF OCTET STRING, - b SET { - a INTEGER, - b INTEGER DEFAULT 66}, - c CHOICE { - a INTEGER, - b FooType } } - -FooType ::= [3] VisibleString </pre> - <p>The following records are generated because of the type <c>Emb</c>:</p> - <pre> --record('Emb,{a, b, c}). --record('Emb_b',{a, b = asn1_DEFAULT}). % the embedded SET type - </pre> - <p>Values of the <c>Emb</c> type can be assigned like this:</p> - <code type="none"> -V = #'Emb'{a=["qqqq",[1,2,255]], - b = #'Emb_b'{a=99}, - c ={b,"Can you see this"}}. - </code> - <p>For an embedded type of type SEQUENCE/SET in a SEQUENCE/SET - the record name is extended with an underscore and the component - name. If the embedded structure is deeper with SEQUENCE, SET or - CHOICE types in the line, each component-/alternative-name will - be added to the record-name.</p> - <p>For example:</p> - <pre> -Seq ::= SEQUENCE{ - a CHOICE{ - b SEQUENCE { - c INTEGER - } - } -} </pre> - <p>will result in the following record:</p> - <pre> --record('Seq_a_b',{c}). </pre> - <p>If the structured type has a component with an embedded - SEQUENCE OF/SET OF which embedded type in turn is a - SEQUENCE/SET it will give a record with the SEQOF/SETOF - addition as in the following example:</p> - <pre> -Seq ::= SEQUENCE { - a SEQUENCE OF SEQUENCE { - b - } - c SET OF SEQUENCE { - d - } -} </pre> - <p>This results in the records:</p> - <pre> --record('Seq_a_SEQOF'{b}). --record('Seq_c_SETOF'{d}). </pre> - <p>A parameterized type should be considered as an embedded - type. Each time a such type is referenced an instance of it is - defined. Thus in the following example a record with name - <c>'Seq_b'</c> is generated in the .hrl file and used to hold - values.</p> - <pre> -Seq ::= SEQUENCE { - b PType{INTEGER} -} - -PType{T} ::= SEQUENCE{ - id T -} </pre> - </section> - - <section> - <title>Recursive Types</title> - <p>Types may refer to themselves. Suppose:</p> - <pre> -Rec ::= CHOICE { - nothing NULL, - something SEQUENCE { - a INTEGER, - b OCTET STRING, - c Rec }} </pre> - <p>This type is recursive; that is, it refers to itself. This is allowed - in ASN.1 and the ASN.1-to-Erlang compiler supports this recursive - type. A value for this type is assigned in Erlang as shown below:</p> - <pre> -V = {something,#'Rec_something'{a = 77, - b = "some octets here", - c = {nothing,'NULL'}}}. </pre> - </section> - </section> - - <section> - <title>ASN.1 Values</title> - <p>Values can be assigned to ASN.1 type within the ASN.1 code - itself, as opposed to the actions taken in the previous chapter where - a value was assigned to an ASN.1 type in Erlang. The full value - syntax of ASN.1 is supported and [X.680] describes in detail how - to assign values in ASN.1. Below is a short example:</p> - <pre> -TT ::= SEQUENCE { - a INTEGER, - b SET OF OCTET STRING } - -tt TT ::= {a 77,b {"kalle","kula"}} </pre> - <p>The value defined here could be used in several ways. - Firstly, it could be used as the value in some DEFAULT component:</p> - <pre> -SS ::= SET { - s OBJECT IDENTIFIER, - val TT DEFAULT tt } </pre> - <p>It could also be used from inside an Erlang program. If the above ASN.1 - code was defined in ASN.1 module <c>Values</c>, then the ASN.1 value - <c>tt</c> can be reached from Erlang as - a function call to <c>'Values':tt()</c> as in the example below.</p> - <pre> -1> <input>Val = 'Values':tt().</input> -{'TT',77,["kalle","kula"]} -2> <input>{ok,Bytes} = 'Values':encode('TT',Val).</input> -{ok,<<48,18,128,1,77,161,13,4,5,107,97,108,108,101,4,4, - 107,117,108,97>>} -4> <input>'Values':decode('TT',Bytes).</input> -{ok,{'TT',77,["kalle","kula"]}} -5> - </pre> - <p>The above example shows that a function is generated by the compiler - that returns a valid Erlang representation of the value, even though - the value is of a complex type.</p> - <p>Furthermore, there is a macro generated for each value in the .hrl - file. So, the defined value <c>tt</c> can also be extracted by - <c>?tt</c> in application code.</p> - </section> - - <section> - <title>Macros</title> - <p>MACRO is not supported as the the type is no longer part of the - ASN.1 standard.</p> - </section> - - <section> - <marker id="Information Object"></marker> - <title>ASN.1 Information Objects (X.681)</title> - <p>Information Object Classes, Information Objects and Information - Object Sets (in the following called classes, objects and - object sets respectively) are defined in the standard - definition [<cite id="X.681"></cite>]. In the following only a brief - explanation is given. </p> - <p>These constructs makes it possible to define open types, - i.e. values of that type can be of any ASN.1 type. It is also - possible to define relationships between different types and - values, since classes can hold types, values, objects, object - sets and other classes in its fields. - An Information Object Class may be defined in ASN.1 as:</p> - <pre> -GENERAL-PROCEDURE ::= CLASS { - &Message, - &Reply OPTIONAL, - &Error OPTIONAL, - &id PrintableString UNIQUE -} -WITH SYNTAX { - NEW MESSAGE &Message - [REPLY &Reply] - [ERROR &Error] - ADDRESS &id -} </pre> - <p>An object is an instance of a class and an object set is a set - containing objects of one specified class. A definition may look like - below.</p> - <p>The object <c>object1</c> is an instance of the CLASS - GENERAL-PROCEDURE and has one type field and one fixed type value - field. The object <c>object2</c> also has an OPTIONAL field ERROR, - which is a type field.</p> - <pre> -object1 GENERAL-PROCEDURE ::= { - NEW MESSAGE PrintableString - ADDRESS "home" -} - -object2 GENERAL-PROCEDURE ::= { - NEW MESSAGE INTEGER - ERROR INTEGER - ADDRESS "remote" -} </pre> - <p>The field ADDRESS is a UNIQUE field. Objects in an object set must - have unique values in their UNIQUE field, as in GENERAL-PROCEDURES: </p> - <pre> -GENERAL-PROCEDURES GENERAL-PROCEDURE ::= { - object1 | object2} </pre> - <p>One can not encode a class, object or object set, only referring to - it when defining other ASN.1 entities. Typically one refers to a - class and to object sets by table constraints and component - relation constraints [<cite id="X.682"></cite>] in ASN.1 types, as in: </p> - <pre> -StartMessage ::= SEQUENCE { - msgId GENERAL-PROCEDURE.&id ({GENERAL-PROCEDURES}), - content GENERAL-PROCEDURE.&Message ({GENERAL-PROCEDURES}{@msgId}), - } </pre> - <p>In the type <c>StartMessage</c> the constraint following the - <c>content</c> field tells that in a value of type - <c>StartMessage</c> the value in the <c>content</c> field must - come from the same object that is chosen by the <c>msgId</c> - field.</p> - <p>So, the value <c>#'StartMessage'{msgId="home",content="Any Printable String"}</c> is legal to encode as a StartMessage - value, while the value <c>#'StartMessage'{msgId="remote", content="Some String"}</c> is illegal since the constraint - in StartMessage tells that when you have chosen a value from a - specific object in the object set GENERAL-PROCEDURES in the - msgId field you have to choose a value from that same object in - the content field too. In this second case it should have been - any INTEGER value.</p> - <p><c>StartMessage</c> can in the <c>content</c> field be - encoded with a value of any type that an object in the - <c>GENERAL-PROCEDURES</c> object set has in its <c>NEW MESSAGE</c> field. This field refers to a type field - <c>&Message</c> in the class. The <c>msgId</c> field is always - encoded as a PrintableString, since the field refers to a fixed type - in the class.</p> - <p>In practice, object sets are usually declared to be extensible so - so that more objects can be added to the set later. Extensibility is - indicated like this:</p> - <pre> -GENERAL-PROCEDURES GENERAL-PROCEDURE ::= { - object1 | object2, ...} </pre> - <p>When decoding a type that uses an extensible set constraint, - there is always the possibility that the value in the UNIQUE - field is unknown (i.e. the type has been encoded with a later - version of the ASN.1 specification). When that happens, the - unencoded data will be returned wrapped in a tuple like this:</p> - - <pre> -{asn1_OPENTYPE,Binary}</pre> - <p>where <c>Binary</c> is an Erlang binary that contains the encoded - data. (If the option <c>legacy_erlang_types</c> has been given, - just the binary will be returned.)</p> - </section> - - <section> - <title>Parameterization (X.683)</title> - <p>Parameterization, which is defined in the standard [<cite id="X.683"></cite>], can be used when defining types, values, value - sets, information object classes, information objects or - information object sets. - A part of a definition can be supplied as a parameter. For - instance, if a Type is used in a definition with certain - purpose, one want the type-name to express the intention. This - can be done with parameterization.</p> - <p>When many types (or another ASN.1 entity) only differs in some - minor cases, but the structure of the types are similar, only - one general type can be defined and the differences may be supplied - through parameters. </p> - <p>One example of use of parameterization is:</p> - <pre> -General{Type} ::= SEQUENCE -{ - number INTEGER, - string Type -} - -T1 ::= General{PrintableString} - -T2 ::= General{BIT STRING} - </pre> - <p>An example of a value that can be encoded as type T1 is {12,"hello"}.</p> - <p>Note that the compiler does not generate encode/decode functions for - parameterized types, but only for the instances of the parameterized - types.

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"''' +%% @end + +-module(merl). + +-export([term/1, var/1, print/1, show/1]). + +-export([quote/1, quote/2, qquote/2, qquote/3]). + +-export([template/1, tree/1, subst/2, tsubst/2, alpha/2, match/2, switch/2]). + +-export([template_vars/1, meta_template/1]). + +-export([compile/1, compile/2, compile_and_load/1, compile_and_load/2]). + +%% NOTE: this module may not include merl.hrl! + +-type tree() :: erl_syntax:syntaxTree(). + +-type tree_or_trees() :: tree() | [tree()]. + +-type pattern() :: tree() | template(). + +-type pattern_or_patterns() :: pattern() | [pattern()]. + +-type env() :: [{Key::id(), pattern_or_patterns()}]. + +-type id() :: atom() | integer(). + +%% A list of strings or binaries is assumed to represent individual lines, +%% while a flat string or binary represents source code containing newlines. +-type text() :: string() | binary() | [string()] | [binary()]. + +-type location() :: erl_anno:location(). + + +%% ------------------------------------------------------------------------ +%% Compiling and loading code directly to memory + +%% @equiv compile(Code, []) +compile(Code) -> + compile(Code, []). + +%% @doc Compile a syntax tree or list of syntax trees representing a module +%% into a binary BEAM object. +%% @see compile_and_load/2 +%% @see compile/1 +compile(Code, Options) when not is_list(Code)-> + case type(Code) of + form_list -> compile(erl_syntax:form_list_elements(Code)); + _ -> compile([Code], Options) + end; +compile(Code, Options0) when is_list(Options0) -> + Forms = [erl_syntax:revert(F) || F <- Code], + Options = [verbose, report_errors, report_warnings, binary | Options0], + compile:noenv_forms(Forms, Options). + + +%% @equiv compile_and_load(Code, []) +compile_and_load(Code) -> + compile_and_load(Code, []). + +%% @doc Compile a syntax tree or list of syntax trees representing a module +%% and load the resulting module into memory. +%% @see compile/2 +%% @see compile_and_load/1 +compile_and_load(Code, Options) -> + case compile(Code, Options) of + {ok, ModuleName, Binary} -> + _ = code:load_binary(ModuleName, "", Binary), + {ok, Binary}; + Other -> Other + end. + + +%% ------------------------------------------------------------------------ +%% Utility functions + + +-spec var(atom()) -> tree(). + +%% @doc Create a variable. + +var(Name) -> + erl_syntax:variable(Name). + + +-spec term(term()) -> tree(). + +%% @doc Create a syntax tree for a constant term. + +term(Term) -> + erl_syntax:abstract(Term). + + +%% @doc Pretty-print a syntax tree or template to the standard output.
