2015-02-27Updated `README.md` to mention the examples and added build instructionsAdrian Kummerlaender
2015-02-27Renamed `Any` list query to `Every`Adrian Kummerlaender
* _TypeAsValue_ borrows large parts of its inspirations from _Scheme_ ** i.e. there is no reason for stopping at this point
2015-02-26Enabled `Concatenate` to concatenate a variadic pack of listsAdrian Kummerlaender
* analogously to arbitrary list count concatenation in Scheme's `append` ** implemented for `Concatenate` instead as it fits better with the structure between `Append` and `Concatenate`
2015-02-25Added `Cond` branch condition assertionAdrian Kummerlaender
* improves error messages in case no branch condition resolves to `true`
2015-02-24Replaced `utility::defer_eval` with placeholder-less `Apply`Adrian Kummerlaender
* usage of `Apply` sans placeholders was already possible and as such duplicated `utility::defer_eval` * renamed `apply_none`'s type alias from to `type` to enable combining it with `Eval`
2015-02-23Added binary incrementer state table to Turing machine exampleAdrian Kummerlaender
* reintroduced `BLANK` as the _BLANK_ symbol * fixed implicit tape expansion in `tape::readSymbol`
2015-02-22Improved `simulate` function of the Turing machine exampleAdrian Kummerlaender
* introduced `state::state_accessor` helper function and moved position logic into `updatePosition` * added `IsEqual` comparator and expressed other basic comparators in terms of itself
2015-02-21Added `README.md` to the Turing machine exampleAdrian Kummerlaender
2015-02-21Moved Turing machine printing into separate functionAdrian Kummerlaender
2015-02-21Separated Turing machine implementation into componentsAdrian Kummerlaender
* i.e. separate namespaces and headers for _Tape_ and _State_ functions * `void` is now used as the `BLANK` field value
2015-02-21Implemented basic Turing machine as an exampleAdrian Kummerlaender
* executes and prints the _Busy Beaver_ and _Mirror_ state transitions * this example demonstrates how one may use _TypeAsValue_ to simplify and augment normal statically recursive template metaprograms where it makes sense
2015-02-20Added `ReplaceNth` list operationAdrian Kummerlaender
* as its name implies this function replaces the _nth_ element of a given list * added appropriate test case
2015-02-19Moved `Apply`'s placeholder into separate detail headerAdrian Kummerlaender
* separate actual `Apply` specializations in `detail/apply.h` from placeholder details
2015-02-19Introduced `Branch` and `Else` pair aliases for usage in `Cond`Adrian Kummerlaender
* pure _syntax sugar_ to improve readability of `Cond` conditionals
2015-02-19Added missing `Cond` dependency headersAdrian Kummerlaender
2015-02-19Reimplemented `Find` in terms of `ListIndex`Adrian Kummerlaender
* `ListIndex` already implements the necessary partial template specializations for finding elements matching a predicate * reimplemented `Cond` using `detail::find_variadic` as `Find` depends on `Apply` which in turn depends on `Cond` ** it is useful if core functionality such as the branched conditional `Cond` do not require higher order functionality such as `Find` *** otherwise one can not use core functionality in the implementation of higher order functionality * introduced `utility::predicate_guard` helper template ** checks a given value using a predicate and only forwards the value to the guarded function if this check is successful ** if check is unsuccessful it returns a surrogate value simmilar to `utility::predicate_assurance`
2015-02-18Changed `ListIndex` to return false if no index is foundAdrian Kummerlaender
* analogously to `list-index` and `find` in SRFI-1
2015-02-18Reimplemented `Append` in terms of `Fold`Adrian Kummerlaender
* `Fold` already implements the necessary partial specializations for traversing list structures
2015-02-17Reimplemented `TakeWhile` and `DropWhile` in terms of `ListIndex`Adrian Kummerlaender
* new higher order list operation `ListIndex` returns the index of the first list element satisfying a given predicate function ** this enables finding the split index required for both `TakeWhile` and `DropWhile` ** actual list manipulation is then performed using lower order `Take` or `Drop` ** analogously to `list-index` in SRFI-1 ** added appropriate test case * added higher order predicate utility function `utility::predicate_assurance` ** as its name implies this function enables assuring that a value satisfies a given predicate *** if this is not the case a surrogate value is returned instead ** this is used to return a appropriate size value if the `ListIndex` call fails because no element satisfies its predicate ** `detail::predicate_negator` was moved from `Remove`'s implementation details into the newly introduced `utility` namespace *** as it is required by both `TakeWhile` and `DropWhile` in addition to `Remove` * continuation of 8e49cc6
2015-02-17Added `Section` test caseAdrian Kummerlaender
* as its name implies `Section` enables the extraction of a section of a given list ** a section is defined by its start and end index
2015-02-17Expressed `Take` and `Drop` in terms of new `Section` operationAdrian Kummerlaender
* unifies the common functionality between `Take` and `Drop` * renamed `basic.h` to `length.h` as it only contains the `Length` implementation
2015-02-16Unified `Iota` and `MakeList` using nested structure generatorAdrian Kummerlaender
* `detail::generate_nested_structure` offers a higher order nested structure constructor for procedural list generation * renamed `Fold` implementation details
2015-02-16Renamed `detail::Sort` to `detail::quick_sort`Adrian Kummerlaender
* opens up the possibility of implementing different sort algorithms in this library * removed now unnecessary namespace prefixes
2015-02-16Reimplemented `Nth` in terms of `Drop`Adrian Kummerlaender
2015-02-16Simplified `List`, `Length` and `Reverse` implementationsAdrian Kummerlaender
* continuation of 8e49cc6 * list constructor was generalized to a _variadic fold_
2015-02-15Simplified `Cond`, `Cons` and `Map` implementationsAdrian Kummerlaender
* continuation of 8e49cc6f8f
2015-02-15Reduced `Filter` and `Remove` implementations to direct aliasesAdrian Kummerlaender
* i.e. instead of defining full class templates in the `detail` namespace we only define predicate helpers * I don't like how some symbols have to be prefixed with `tav::` in the `detail` namespace to prevent conflicts - this is one reason why as much implementation as possible should be moved to template aliases
2015-02-15Moved class-based implementations into `detail` namespaceAdrian Kummerlaender
* while class templates enable e.g. hiding implementation details they also require evaluation via `Eval` ** this clutters up the actual logic and is now hidden behind aliae that perform the evaluation
2015-02-14Introduced `Eval` function evaluation helperAdrian Kummerlaender
* replaces `typename *::type` constructs with `Eval` applications * aims to further unify function evaluation
2015-02-13Renamed `Apply`'s template alias to `function`Adrian Kummerlaender
* `type` is used to represent evaluation of a template * accessing the `function` doesn't evaluate it as it is the template itself
2015-02-12Added previously missing `Drop` implementationAdrian Kummerlaender
2015-02-12Implemented `Cond` conditionalAdrian Kummerlaender
* returns the `CDR` of the first true `CAR` in a given list of pairs * reimplemented `Apply` base class selection in terms of `Cond`
2015-02-12Added `Is` prefix to `EqualValue` and `EqualType`Adrian Kummerlaender
* analogously to `IsPair`
2015-02-12Revamped partial function applicationAdrian Kummerlaender
* moved internals into separate header i.e. the `detail` namespace relating to `Apply` * implemented automatic alias selection by implementing aliae of the basic variadic `type` template alias in different base classes ** variadic partial application is implemented in `detail::apply_variadic` *** `detail::apply_single` and `detail::apply_pair` define aliae to `detail::apply_variadic`'s `type` template alias *** both restricted aliae derive from `detail::apply_variadic` ** `Apply` derives from any of the aliae defining base classes depending on the count of placeholders as determined by `detail::count_placeholders` *** `Apply` is guaranteed to always be derived from `detail::apply_variadic` one way or the other * changed functions, test cases and examples depending on `Apply` accordingly ** `Length` had to be reimplemented without `Apply` as it doesn't allow usage of aliae expecting a different count of arguments anymore *** this is a advantage in the sense that core functionality of _TypeAsValue_ now doesn't depend on this complex partial application implementation anymore *** such functionality may be reimplemented separately from `Apply` * removed unnecessary `tav` namespace prefixes
2015-02-10Moved `Sort` list index deletion into `DeleteNth` functionAdrian Kummerlaender
* as it is commonly required functionality and as such should be provided by this library
2015-02-09Updated `README.md` to mention recent features and directionAdrian Kummerlaender
2015-02-09Updated `Sort` to make use of `Partition` for splitting at pivotAdrian Kummerlaender
* added further test cases for `Sort` as well as `Nth` aliae
2015-02-09Added `First`, `Second` and `Third` aliae for `Nth`Adrian Kummerlaender
* increases expressiveness in some contexts * renamed `Partition` list template parameter to avoid confusion
2015-02-09Added `void` concatenation `List` template specializationAdrian Kummerlaender
* otherwise a type conflict occurs when trying to instantiate a list of `void` ** this hinders construction of higher level functionality on top of `List`
2015-02-08Implemented higher order `Sort` list operationAdrian Kummerlaender
* _Quicksort_ is the algorithm of choice ** it lends itself quite well to the _TypeAsValue_ approach because of its recursive nature ** this required implementation of a `Drop` counterpart to `Take` * the middle item of a given list is selected as the _pivot_ element * the `List` list contructor had to be expanded to allow `void` arguments inside its variadic parameter pack * added appropriate test cases
2015-02-08Added `GreaterThan` and `LowerThan` comparatorsAdrian Kummerlaender
2015-02-08Added _Scheme_ variant of prime example as documentationAdrian Kummerlaender
2015-02-06Moved _SFINAE_ helper into separate headerAdrian Kummerlaender
2015-02-06Revamped to use `Cons` as a function and `Pair` as its resultAdrian Kummerlaender
* this is analogous to _Scheme_ where a pair (dot-expression) is returned from a call to `cons` * `Head` and `Tail` are kept as direct references to the `CAR` and `CDR` values of a pair to match e.g. the math operators
2015-02-05Defer `If` template resolution analogously to other functionsAdrian Kummerlaender
* all other functions sans `Cons` are resolved when the respective member `*::type` is instantiated * this was changed soely to increase coherence
2015-02-05Reimplemented `Contains` and `Delete` in terms of `Apply`Adrian Kummerlaender
* both depict the very usecase partial function application via `Apply` is suited for
2015-02-05Reimplemented `removeMultiplesOf` in terms of a partial function applicationAdrian Kummerlaender
2015-02-04Implemented the Sieve of Eratosthenes as a basic exampleAdrian Kummerlaender
2015-02-03Added special `for_each` function for iterating lists at runtimeAdrian Kummerlaender
* i.e. we probably will want to access our compile time computed values at runtime sooner or later * runtime iteration using e.g. a normal _for-loop_ is not possible as we obviously can't dynamically insert new types into our templates
2015-02-02Implemented `Delete` in terms of `Remove`Adrian Kummerlaender
* analogously to how `Contains` is implemented as a wrapper around `Any` * added appropriate test case and lessened restrictions on `Contains`'s comparator
