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.

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.

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.
