An assertion in Snowhouse is written +using the following format: + +```cpp +AssertThat(actual_value, <constraint expression>); +``` + +where <constraint expression> is an expression that actual_value is evaluated against when the test is executed. + +Constraint expressions come in two basic forms: composite and fluent expressions + +#### Composite Expressions + +With composite expressions, you can create compact, powerful expressions that combine a set of predefined constraints with ones that you provide yourself. + +Example: + +```cpp +AssertThat(length, IsGreaterThan(4) && !Equals(10)); +``` + +Composite expressions can be any combination of constraints and the standard logical C++ operators. + +You can also add your own constraints to be used within composite expressions. + +####Fluent Expressions + +With fluent expressions, you can create assertions that better convey the intent of a test without exposing implementation-specific details. Fluent expressions aim to help you create tests that are not just by developers for developers, but rather can be read and understood by domain experts. + +Fluent expressions also has the ability to make assertions on the elements in a conteiner in a way you cannot achieve with composite expressions. + +Example: + +```cpp +AssertThat(length, Is().GreaterThan(4).And().Not().EqualTo(10)); +``` + +### Basic Constraints + +####Equality Constraint + +Used to verify equality between actual and expected. + +```cpp +AssertThat(x, Equals(12)); +AssertThat(x, Is().EqualTo(12)); +``` + +####EqualityWithDelta Constraint + +Used to verify equality between actual and expected, allowing the two to differ by a delta. + +```cpp +AssertThat(2.49, EqualsWithDelta(2.5, 0.1)); +AssertThat(2.49, Is().EqualToWithDelta(2.5, 0.1)); +``` + +####GreaterThan Constraint + +Used to verify that actual is greater than a value. + +```cpp +AssertThat(x, IsGreaterThan(4)); +AssertThat(x, Is().GreaterThan(4)); +``` + + +####LessThan Constraint + +Used to verify that actual is less than a value. + +```cpp +AssertThat(x, IsLessThan(3)); +AssertThat(x, Is().LessThan(3)); +``` + +####GreaterThanOrEqualTo Constraint + +Used to verify that actual is greater than or equal to a value. + +```cpp +AssertThat(x, IsGreaterThanOrEqualTo(5)); +AssertThat(x, Is().GreaterThanOrEqualTo(5)); +``` + +####LessThanOrEqualTo Constraint + +Used to verify that actual is less than or equal to a value. + +```cpp +AssertThat(x, IsLessThanOrEqualTo(6)); +AssertThat(x, Is().LessThanOrEqualTo(6)); +``` + +### Pointer Constraints + +Used to check for `nullptr` equality. + +```cpp +AssertThat(x, IsNull()); +AssertThat(x, Is().Null()); +``` + +### String Constraints + +String assertions in Snowhouse are used to verify the values of STL strings (std::string). + +####Equality Constraints + +Used to verify that actual is equal to an expected value. + +```cpp +AssertThat(actual_str, Equals("foo")); +AssertThat(actual_str, Is().EqualTo("foo")); +``` + +####Contains Constraint + +Used to verify that a string contains a substring. + +```cpp +AssertThat(actual_str, Contains("foo")); +AssertThat(actual_str, Is().Containing("foo")); +``` + +####EndsWith Constraint + +Used to verify that a string ends with an expected substring. + +```cpp +AssertThat(actual_str, EndsWith("foo")); +AssertThat(actual_str, Is().EndingWith("foo")); +``` + +####StartsWith Constraint + +Used to verify that a string starts with an expected substring. + +```cpp +AssertThat(actual_str, StartsWith("foo")); +AssertThat(actual_str, Is().StartingWith("foo")); +``` + +####HasLength Constraint + +Used to verify that a string is of the expected length. + +```cpp +AssertThat(actual_str, HasLength(5)); +AssertThat(actual_str, Is().OfLength(5)); +``` + +###Constraints on Multi Line Strings + +If you have a string that contains multiple lines, you can use the collection constraints to make assertions on the content of that string.

See `DefaultFailureHandler` for an example of a failure handler. You can derive your own macros with custom failure handlers using `SNOWHOUSE_ASSERT_THAT` and `SNOWHOUSE_ASSERT_THROWS`. See the definitions of `AssertThat` and `AssertThrows` for examples of these. Define `SNOWHOUSE_NO_MACROS` to disable the unprefixed macros `AssertThat` and `AssertThrows`. + +### Example Use Cases + +#### Assert Program State + +Log an error immediately as we may crash if we try to continue.

Just <code>\#include "optionparser.h"</code> and you're set. + * <li> It is freestanding. There are no dependencies whatsoever, not even the + * C or C++ standard library. + * <li> It has a usage message formatter that supports column alignment and + * line wrapping. This aids localization because it adapts to + * translated strings that are shorter or longer (even if they contain + * Asian wide characters). + * <li> Unlike getopt() and derivatives it doesn't force you to loop through + * options sequentially. Instead you can access options directly like this: + * <ul style="margin-top:.5em"> + * <li> Test for presence of a switch in the argument vector: + * @code if ( options[QUIET] ) ... @endcode + * <li> Evaluate --enable-foo/--disable-foo pair where the last one used wins: + * @code if ( options[FOO].last()->type() == DISABLE ) ... @endcode + * <li> Cumulative option (-v verbose, -vv more verbose, -vvv even more verbose): + * @code int verbosity = options[VERBOSE].count(); @endcode + * <li> Iterate over all --file=<fname> arguments: + * @code for (Option* opt = options[FILE]; opt; opt = opt->next()) + * fname = opt->arg; ... @endcode + * <li> If you really want to, you can still process all arguments in order: + * @code + * for (int i = 0; i < p.optionsCount(); ++i) { + * Option& opt = buffer[i]; + * switch(opt.index()) { + * case HELP: ... + * case VERBOSE: ... + * case FILE: fname = opt.arg; ... + * case UNKNOWN: ... + * @endcode + * </ul> + * </ul> @n + * Despite these features the code size remains tiny. + * It is smaller than <a href="http://uclibc.org">uClibc</a>'s GNU getopt() and just a + * couple 100 bytes larger than uClibc's SUSv3 getopt(). @n + * (This does not include the usage formatter, of course.

You can make the parser accept the additional format @c -X=foo by + * registering @c X as a long option (in addition to being a short option) and + * enabling single-minus long options. + * @li an argument-taking short option may be grouped if it is the last in the group, e.g. + * @c -ABCXfoo or <code> -ABCX foo </code> (@c foo is the argument to the @c -X option). + * @li a lone minus character @c '-' is not treated as an option. It is customarily used where + * a file name is expected to refer to stdin or stdout. + * @li long options have the format @c --option-name. + * @li the option-name of a long option can be anything and include any characters. + * Even @c = characters will work, but don't do that. + * @li [optional] long options may be abbreviated as long as the abbreviation is unambiguous. + * You can set a minimum length for abbreviations. + * @li [optional] long options may begin with a single minus. The double minus form is always + * accepted, too. + * @li a long option may take an argument either separate (<code> --option arg </code>) or + * attached (<code> --option=arg </code>). In the attached form the equals sign is mandatory. + * @li an empty string can be passed as an attached long option argument: <code> --option-name= </code>. + * Note the distinction between an empty string as argument and no argument at all. + * @li an empty string is permitted as separate argument to both long and short options. + * @li Arguments to both short and long options may start with a @c '-' character. E.g. + * <code> -X-X </code>, <code>-X -X</code> or <code> --long-X=-X </code>. If @c -X + * and @c --long-X take an argument, that argument will be @c "-X" in all 3 cases. + * @li If using the built-in @ref option::Arg::Optional "Arg::Optional", optional arguments must + * be attached. + * @li the special option @c -- (i.e. without a name) terminates the list of + * options. Everything that follows is a non-option argument, even if it starts with + * a @c '-' character. The @c -- itself will not appear in the parse results. + * @li the first argument that doesn't start with @c '-' or @c '--' and does not belong to + * a preceding argument-taking option, will terminate the option list and is the + * first non-option argument. All following command line arguments are treated as + * non-option arguments, even if they start with @c '-' . @n + * NOTE: This behaviour is mandated by POSIX, but GNU getopt() only honours this if it is + * explicitly requested (e.g. by setting POSIXLY_CORRECT). @n + * You can enable the GNU behaviour by passing @c true as first argument to + * e.g. @ref option::Parser::parse() "Parser::parse()". + * @li Arguments that look like options (i.e. @c '-' followed by at least 1 character) but + * aren't, are NOT treated as non-option arguments. They are treated as unknown options and + * are collected into a list of unknown options for error reporting. @n + * This means that in order to pass a first non-option + * argument beginning with the minus character it is required to use the + * @c -- special option, e.g. + * @code + * program -x -- --strange-filename + * @endcode + * In this example, @c --strange-filename is a non-option argument. If the @c -- + * were omitted, it would be treated as an unknown option. @n + * See @ref option::Descriptor::longopt for information on how to collect unknown options. + * + */ + +#ifndef OPTIONPARSER_H_ +#define OPTIONPARSER_H_ + +/** @brief The namespace of The Lean Mean C++ Option Parser. */ +namespace option +{ + +#ifdef _MSC_VER +#include <intrin.h> +#pragma intrinsic(_BitScanReverse) +struct MSC_Builtin_CLZ +{ + static int builtin_clz(unsigned x) + { + unsigned long index; + _BitScanReverse(&index, x); + return 32-index; // int is always 32bit on Windows, even for target x64 + } +}; +#define __builtin_clz(x) MSC_Builtin_CLZ::builtin_clz(x) + +#pragma warning( push ) +#pragma warning( disable: 4510 ) +#pragma warning( disable: 4512 ) +#pragma warning( disable: 4610 ) +#pragma warning( disable: 4127 ) +#endif + +class Option; + +/** + * @brief Possible results when checking if an argument is valid for a certain option. + * + * In the case that no argument is provided for an option that takes an + * optional argument, return codes @c ARG_OK and @c ARG_IGNORE are equivalent. + */ +enum ArgStatus +{ + //!
