See the <a href="#index">function index</a> for an overview. +%%% +%%% Types can be combined in tuples or lists to produce other types. Exact +%%% values (such as exact numbers, atoms, binaries and strings) can be combined +%%% with types inside such structures, like in this example of the type of a +%%% tagged tuple: ``{'result', integer()}''. +%%% +%%% When including the PropEr header file, all +%%% <a href="#index">API functions</a> of this module are automatically +%%% imported, unless `PROPER_NO_IMPORTS' is defined. +%%% +%%% == Customized types == +%%% The following operators can be applied to basic types in order to produce +%%% new ones: +%%% +%%% <dl> +%%% <dt>`?LET(<Xs>, <Xs_type>, <In>)'</dt> +%%% <dd>To produce an instance of this type, all appearances of the variables +%%% in `<Xs>' are replaced inside `<In>' by their corresponding values in a +%%% randomly generated instance of `<Xs_type>'. It's OK for the `<In>' part to +%%% evaluate to a type - in that case, an instance of the inner type is +%%% generated recursively.</dd> +%%% <dt>`?SUCHTHAT(<X>, <Type>, <Condition>)'</dt> +%%% <dd>This produces a specialization of `<Type>', which only includes those +%%% members of `<Type>' that satisfy the constraint `<Condition>' - that is, +%%% those members for which the function `fun(<X>) -> <Condition> end' returns +%%% `true'. If the constraint is very strict - that is, only a small +%%% percentage of instances of `<Type>' pass the test - it will take a lot of +%%% tries for the instance generation subsystem to randomly produce a valid +%%% instance. This will result in slower testing, and testing may even be +%%% stopped short, in case the `constraint_tries' limit is reached (see the +%%% "Options" section in the documentation of the {@link proper} module). If +%%% this is the case, it would be more appropriate to generate valid instances +%%% of the specialized type using the `?LET' macro. Also make sure that even +%%% small instances can satisfy the constraint, since PropEr will only try +%%% small instances at the start of testing. If this is not possible, you can +%%% instruct PropEr to start at a larger size, by supplying a suitable value +%%% for the `start_size' option (see the "Options" section in the +%%% documentation of the {@link proper} module).</dd> +%%% <dt>`?SUCHTHATMAYBE(<X>, <Type>, <Condition>)'</dt> +%%% <dd>Equivalent to the `?SUCHTHAT' macro, but the constraint `<Condition>' +%%% is considered non-strict: if the `constraint_tries' limit is reached, the +%%% generator will just return an instance of `<Type>' instead of failing, +%%% even if that instance doesn't satisfy the constraint.</dd> +%%% <dt>`?SHRINK(<Generator>, <List_of_alt_gens>)'</dt> +%%% <dd>This creates a type whose instances are generated by evaluating the +%%% statement block `<Generator>' (this may evaluate to a type, which will +%%% then be generated recursively). If an instance of such a type is to be +%%% shrunk, the generators in `<List_of_alt_gens>' are first run to produce +%%% hopefully simpler instances of the type. Thus, the generators in the +%%% second argument should be simpler than the default. The simplest ones +%%% should be at the front of the list, since those are the generators +%%% preferred by the shrinking subsystem. Like the main `<Generator>', the +%%% alternatives may also evaluate to a type, which is generated recursively. +%%% </dd> +%%% <dt>`?LETSHRINK(<List_of_variables>, <List_of_types>, <Generator>)'</dt> +%%% <dd>This is created by combining a `?LET' and a `?SHRINK' macro. Instances +%%% are generated by applying a randomly generated list of values inside +%%% `<Generator>' (just like a `?LET', with the added constraint that the +%%% variables and types must be provided in a list - alternatively, +%%% `<List_of_types>' may be a list or vector type). When shrinking instances +%%% of such a type, the sub-instances that were combined to produce it are +%%% first tried in place of the failing instance.</dd> +%%% <dt>`?LAZY(<Generator>)'</dt> +%%% <dd>This construct returns a type whose only purpose is to delay the +%%% evaluation of `<Generator>' (`<Generator>' can return a type, which will +%%% be generated recursively). Using this, you can simulate the lazy +%%% generation of instances: +%%% ``` stream() -> ?LAZY(frequency([ {1,[]}, {3,[0|stream()]} ])). ''' +%%% The above type produces lists of zeroes with an average length of 3. Note +%%% that, had we not enclosed the generator with a `?LAZY' macro, the +%%% evaluation would continue indefinitely, due to the eager evaluation of +%%% the Erlang language.</dd> +%%% <dt>`non_empty(<List_or_binary_type>)'</dt> +%%% <dd>See the documentation for {@link non_empty/1}.</dd> +%%% <dt>`noshrink(<Type>)'</dt> +%%% <dd>See the documentation for {@link noshrink/1}.</dd> +%%% <dt>`default(<Default_value>, <Type>)'</dt> +%%% <dd>See the documentation for {@link default/2}.</dd> +%%% <dt>`with_parameter(<Parameter>, <Value>, <Type>)'</dt> +%%% <dd>See the documentation for {@link with_parameter/3}.</dd> +%%% <dt>`with_parameters(<Param_value_pairs>, <Type>)'</dt> +%%% <dd>See the documentation for {@link with_parameters/2}.</dd> +%%% </dl> +%%% +%%% == Size manipulation == +%%% The following operators are related to the `size' parameter, which controls +%%% the maximum size of produced instances. The actual size of a produced +%%% instance is chosen randomly, but can never exceed the value of the `size' +%%% parameter at the moment of generation. A more accurate definition is the +%%% following: the maximum instance of `size S' can never be smaller than the +%%% maximum instance of `size S-1'. The actual size of an instance is measured +%%% differently for each type: the actual size of a list is its length, while +%%% the actual size of a tree may be the number of its internal nodes. Some +%%% types, e.g. unions, have no notion of size, thus their generation is not +%%% influenced by the value of `size'. The `size' parameter starts at 1 and +%%% grows automatically during testing. +%%% +%%% <dl> +%%% <dt>`?SIZED(<S>, <Generator>)'</dt> +%%% <dd>Creates a new type, whose instances are produced by replacing all +%%% appearances of the `<S>' parameter inside the statement block +%%% `<Generator>' with the value of the `size' parameter.

Such expressions can be used instead of regular type +%%% constructors in the second argument of `?FORALL's. No extra notation is +%%% required; PropEr will detect which calls correspond to native types by +%%% applying a parse transform during compilation. This parse transform is +%%% automatically applied to any module that includes the `proper.hrl' header +%%% file. You can disable this feature by compiling your modules with +%%% `-DPROPER_NO_TRANS'. Note that this will currently also disable the +%%% automatic exporting of properties. +%%% +%%% The use of native types in properties is subject to the following usage +%%% rules: +%%% <ul> +%%% <li>Native types cannot be used outside of `?FORALL's.</li> +%%% <li>Inside `?FORALL's, native types can be combined with other native +%%% types, and even with PropEr types, inside tuples and lists (the constructs +%%% `[...]', `{...}' and `++' are all allowed).</li> +%%% <li>All other constructs of Erlang's built-in type system (e.g. `|' for +%%% union, `_' as an alias of `any()', `<<_:_>>' binary type syntax and +%%% `fun((...) -> ...)' function type syntax) are not allowed in `?FORALL's, +%%% because they are rejected by the Erlang parser.</li> +%%% <li>Anything other than a tuple constructor, list constructor, `++' +%%% application, local or remote call will automatically be considered a +%%% PropEr type constructor and not be processed further by the parse +%%% transform.</li> +%%% <li>Parametric native types are fully supported; of course, they can only +%%% appear instantiated in a `?FORALL'. The arguments of parametric native +%%% types are always interpreted as native types.</li> +%%% <li>Parametric PropEr types, on the other hand, can take any kind of +%%% argument. You can even mix native and PropEr types in the arguments of a +%%% PropEr type. For example, assuming that the following declarations are +%%% present: +%%% ``` my_proper_type() -> ?LET(...). +%%% -type my_native_type() :: ... .''' +%%% Then the following expressions are all legal: +%%% ``` vector(2, my_native_type()) +%%% function(0, my_native_type()) +%%% union([my_proper_type(), my_native_type()])''' </li> +%%% <li>Some type constructors can take native types as arguments (but only +%%% inside `?FORALL's): +%%% <ul> +%%% <li>`?SUCHTHAT', `?SUCHTHATMAYBE', `non_empty', `noshrink': these work +%%% with native types too</li> +%%% <li>`?LAZY', `?SHRINK', `resize', `?SIZED': these don't work with native +%%% types</li> +%%% <li>`?LET', `?LETSHRINK': only the top-level base type can be a native +%%% type</li> +%%% </ul></li> +%%% <li>Native type declarations in the `?FORALL's of a module can reference any +%%% custom type declared in a `-type' or `-opaque' attribute of the same +%%% module, as long as no module identifier is used.</li> +%%% <li>Typed records cannot be referenced inside `?FORALL's using the +%%% `#rec_name{}' syntax. To use a typed record in a `?FORALL', enclose the +%%% record in a custom type like so: +%%% ``` -type rec_name() :: #rec_name{}. ''' +%%% and use the custom type instead.</li> +%%% <li>`?FORALL's may contain references to self-recursive or mutually +%%% recursive native types, so long as each type in the hierarchy has a clear +%%% base case. +%%% Currently, PropEr requires that the toplevel of any recursive type +%%% declaration is either a (maybe empty) list or a union containing at least +%%% one choice that doesn't reference the type directly (it may, however, +%%% reference any of the types that are mutually recursive with it). This +%%% means, for example, that some valid recursive type declarations, such as +%%% this one: +%%% ``` ?FORALL(..., a(), ...) ''' +%%% where: +%%% ``` -type a() :: {'a','none' | a()}. ''' +%%% are not accepted by PropEr. However, such types can be rewritten in a way +%%% that allows PropEr to parse them: +%%% ``` ?FORALL(..., a(), ...) ''' +%%% where: +%%% ``` -type a() :: {'a','none'} | {'a',a()}. ''' +%%% This also means that recursive record declarations are not allowed: +%%% ``` ?FORALL(..., rec(), ...) ''' +%%% where: +%%% ``` -type rec() :: #rec{}. +%%% -record(rec, {a = 0 :: integer(), b = 'nil' :: 'nil' | #rec{}}). ''' +%%% A little rewritting can usually remedy this problem as well: +%%% ``` ?FORALL(..., rec(), ...) ''' +%%% where: +%%% ``` -type rec() :: #rec{b :: 'nil'} | #rec{b :: rec()}. +%%% -record(rec, {a = 0 :: integer(), b = 'nil' :: 'nil' | #rec{}}). ''' +%%% </li> +%%% <li>Remote types may be referenced in a `?FORALL', so long as they are +%%% exported from the remote module. Currently, PropEr requires that any +%%% remote modules whose types are directly referenced from within properties +%%% are present in the code path at compile time, either compiled with +%%% `debug_info' enabled or in source form. If PropEr cannot find a remote +%%% module at all, finds only a compiled object file with no debug +%%% information or fails to compile the source file, all calls to that module +%%% will automatically be considered calls to PropEr type constructors.</li> +%%% <li>For native types to be translated correctly, both the module that +%%% contains the `?FORALL' declaration as well as any module that contains +%%% the declaration of a type referenced (directly or indirectly) from inside +%%% a `?FORALL' must be present in the code path at runtime, either compiled +%%% with `debug_info' enabled or in source form.</li> +%%% <li>Local types with the same name as an auto-imported BIF are not accepted +%%% by PropEr, unless the BIF in question has been declared in a +%%% `no_auto_import' option.</li> +%%% <li>When an expression can be interpreted both as a PropEr type and as a +%%% native type, the former takes precedence. This means that a function +%%% `foo()' will shadow a type `foo()' if they are both present in the module. +%%% The same rule applies to remote functions and types as well.</li> +%%% <li>The above may cause some confusion when list syntax is used: +%%% <ul> +%%% <li>The expression `[integer()]' can be interpreted both ways, so the +%%% PropEr way applies. Therefore, instances of this type will always be +%%% lists of length 1, not arbitrary integer lists, as would be expected +%%% when interpreting the expression as a native type.</li> +%%% <li>Assuming that a custom type foo/1 has been declared, the expression +%%% `foo([integer()])' can only be interpreted as a native type declaration, +%%% which means that the generic type of integer lists will be passed to +%%% `foo/1'.</li> +%%% </ul></li> +%%% <li>Currently, PropEr does not detect the following mistakes: +%%% <ul> +%%% <li>inline record-field specializations that reference non-existent +%%% fields</li> +%%% <li>type parameters that are not present in the RHS of a `-type' +%%% declaration</li> +%%% <li>using `_' as a type variable in the LHS of a `-type' declaration</li> +%%% <li>using the same variable in more than one position in the LHS of a +%%% `-type' declaration</li> +%%% </ul> +%%% </li> +%%% </ul> +%%% +%%% You can use <a href="#index">these</a> functions to try out the type +%%% translation subsystem. +%%% +%%% CAUTION: These functions should never be used inside properties.

This - increases the readability of the code and the logic might be - possible to reuse.</p> - - <section> - <title>The *.tool file</title> - <p>When WebTool starts it searches the current path for - <c>*.tool</c> files to find all available tools. The *.tool - file contains a version identifier and a list of tuples which - is the configuration data. The version identifier specifies - the *.tool file version, i.e. not the version of - webtool. Currently the only valid version is "1.2" and the - only valid configuration tag is - <c>config_func</c>. <c>config_func</c> specifies which - function WebTool must call to get further configuration data - for the tool. This means that a *.tool file generally must - look like this:</p> - <code type="none"> - {version,"1.2"}. - [{config_func,{Module,Function,Arguments}}]. </code> - <p><c>Module</c> is the name of the module where the callback - function is defined. <c>Function</c> is the name of the - callback function, and <c>Arguments</c> is the list of - arguments to the callback function.</p> - </section> - - <section> - <title>The configuration function</title> - <p>The *.tool file points out a configuration function. This - function must return a list of configuration parameters (see - the Reference Manual for <seealso marker="webtool">webtool</seealso>).</p> - <p>The <c>web_data</c> parameter is mandatory and it specifies - the name of the tool and the link to the tool's start - page. All other parameters are optional.</p> - <p>If the tool requires any processes to run, the <c>start</c> - parameter specifies the function that WebTool must call in - order to start the process(es).</p> - <p>The <c>alias</c> parameters are passed directly on to the - webserver (INETS). The webserver has three ways to create - dynamic web pages CGI, Eval Scheme and Erl Scheme. All tools - running under WebTool must use Erl Scheme.</p> - <p>Erl Scheme tries to resemble plain CGI. The big difference is - that Erl Scheme can only execute Erlang code. The code will - furthermore be executed on the same instance as the webserver.</p> - <p>An URL which calls an Erlang function with Erl Scheme can have - the following syntax:</p> - <code type="none"><![CDATA[ -http://Servername:Port/ErlScriptAlias/Mod/Func<?QueryString> ]]></code> - <p>An <c>alias</c> parameter in the configuration function can be - an ErlScriptAlias as used in the above URL. The definition of - an ErlScriptAlias shall be like this:</p> - <p><c>{alias,{erl_alias,Path,[Modules]}}</c>, e.g.</p> - <p><c>{alias,{erl_alias,"/testtool",[helloworld]}}</c></p> - <p>The following URL will then cause a call to the function - helloworld:helloworld/2 (if WebTool is started with default - settings i.e. servername "localhost" and port 8888):</p> - <p><c>http://localhost:8888/testtool/helloworld/helloworld</c></p> - <p>Note that the module <c>helloworld</c> must be in the code - path of the node running WebTool.</p> - <p>Functions that are called via the Erl Scheme must take two - arguments, <c>Environment</c> and <c>Input</c>. - </p> - <list type="bulleted"> - <item><c>Environment</c> is a list of key/value tuples.</item> - <item><c>Input</c> is the part of the URL after the "?", i.e. the - part of the URL containing name-value pairs. If the page was - called with the URL: - <br></br> -<c><![CDATA[http://localhost:8888/testtool/helloworld/helloworld?input1=one&input2=two]]></c> <br></br> -<c>Input</c> will be the string - <c><![CDATA["input1=one&input2=two"]]></c>. In the module - <c>httpd</c> in the INETS application there is a function - <c>parse_query</c> which will parse such a string and return - a list of key-value tuples.</item> - </list> - <p>An <c>alias</c> parameter in the configuration function can - also be a normal path alias. This can e.g. be used to point - out a directory where HTML files are stored. The following - definition states that the URL - <c>http://localhost:8888/mytool_home/</c> really points to the - directory <c>/usr/local/otp/lib/myapp-1.0/priv</c>:</p> - <p><c>{alias,{"/mytool_home","/usr/local/otp/lib/myapp-1.0/priv"}}</c></p> - <p>See the INETS documentation, especially the module - <c>mod_esi</c>, for a more in depth coverage of the Erl Scheme.</p> - </section> - - <section> - <title>A small example</title> - <p>A Hello World example that uses Erl Scheme would look like - this. Note that this example does not have a process running - and thus does not need a <c>start</c> parameter in the - configuration function. - </p> - <p><em>helloworld.erl:</em></p> - <pre> - -module(helloworld). - -export([config_data/0]). - -export([helloworld/2]). - - config_data()-> - {testtool, - [{web_data,{"TestTool","/testtool/helloworld/helloworld"}}, - {alias,{erl_alias,"/testtool",[helloworld]}}]}. - - helloworld(_Env,_Input)-> - [header(),html_header(),helloworld_body(),html_end()]. - - header() -> - header("text/html"). - - header(MimeType) -> - "Content-type: " ++ MimeType ++ "\r\n\r\n". - - html_header() -> - "<HTML> - <HEAD> - <TITLE>Hello world Example </TITLE> - </HEAD>\n". - - helloworld_body()-> - "<BODY>Hello World</BODY>". - - html_end()-> - "</HTML>". - </pre> - <p>To use this example with WebTool a *.tool file must be created - and added to a directory in the current path, e.g. the same - directory as the compiled <c>helloworld.beam</c>.</p> - <p><em>testtool.tool:</em></p> - <code type="none"> - {version,"1.2"}. - [{config_func, {helloworld,config_data,[]}}]. - </code> - <p>When <c>helloworld.erl</c> is compiled, start WebTool by - calling the function <c>webtool:start()</c> and point your - browser to <em>http://localhost:8888/</em>.
