Implement copy_if_while and copy_if_until
2022-06-28 17:46:45 -07:00
eec00d8421 Implement copy_if_while and copy_if_until
Problem:
- There is no way to signal that a copy should proceed, selecting
  elements by a predicate until some condition is met. This is useful
  for patterns along the lines of "copy selected elements until there
  are n total elements in the output".

Solution:
- Introduce `copy_if_while()` and `copy_if_until()`.

[skip ci] Add "cxxstd" json field
2021-01-18 18:26:35 -08:00
137c92dac0 [skip ci] Add "cxxstd" json field. The "cxxstd" json field is being added to each Boost library's meta json information for libraries in order to specify the minumum C++ standard compilation level. The value of this field matches one of the values for 'cxxstd' in Boost.Build. The purpose of doing this is to provide information for the Boost website documentation for each library which will specify the minimum C++ standard compilation that an end-user must employ in order to use the particular library. This will aid end-users who want to know if they can successfully use a Boost library based on their C++ compiler's compilation level, without having to search the library's documentation to find this out. 2021-01-18 20:32:12 -05:00

45baad2431 Correct lvalue/rvalue nomenclature
I accidentally referred to the additional tests as using lvalues as inputs, when they’re actually using rvalues. This commit corrects the relevant comments.
2018-08-02 22:18:54 +01:00
5408a17020 Add tests with lvalue inputs
If the compiler supports forwarding references, we now test if lvalues can be used as input strings for split(), find_all(), and ifind_all().

Note that MSVC (without its recent /permissive- flag) may pass these tests without the forwarding references changes that I made, due to its non-standard binding of lvalues to rvalues.
2018-08-01 22:42:18 +01:00
c6f784cb70 Use forwarding references in string/split.hpp
On compilers that support C++11, this allows both lvalues and rvalues to be used as inputs to the split(), find_all(), and ifind_all() functions.

For example, given a function get_string() that returns a std::string, this allows you to write:
boost::split(result, get_string(), boost::is_any_of(" "))

42bbfdeb4c Deleted support for nullptr, NULL and 0.
I think user shouldn't send to 'is_palindrome' zero, NULL or nullptr as parameter. As value of const char* it's possible, of course. But cases 'is_palindrome(0)', 'is_palindrome(NULL)' and 'is_palindrome(nullptr)' is silly and it should be restricted by design.

# Generic Travis CI build script for boostorg repositories
# See: https://github.com/boostorg/boost-ci

# Instructions for customizing this script for your library:
#
# 1. Customize the compilers and language levels you want in the 'jobs'.
# 2. If you have more than include/, src/, test/, example/, examples/, or

# variable DEPINST. For example if your build uses code in "bench/" and
# "fog/" directories, then set DEPINST to the following:
# --include bench --include fog
# 3. If you want to enable Coverity Scan, you need to provide the environment
# variables COVERITY_SCAN_TOKEN and COVERITY_SCAN_NOTIFICATION_EMAIL in
# your github settings.
# 4. Enable pull request builds in your boostorg/<library> account.
#
# That's it - the scripts will do everything else for you.

The header file [^[link header.boost.algorithm.apply_permutation_hpp apply_permutation.hpp]] contains two algorithms, `apply_permutation` and `apply_reverse_permutation`. There are also range-based versions.
The algorithms transform the item sequence according to index sequence order.
The routine `apply_permutation` takes a item sequence and a order sequence. It reshuffles item sequence according to order sequence. Every value in order sequence means where the item comes from. Order sequence needs to be exactly a permutation of the sequence [0, 1, ... , N], where N is the biggest index in the item sequence (zero-indexed).
The routine `apply_reverse_permutation` takes a item sequence and a order sequence. It will reshuffle item sequence according to order sequence. Every value in order sequence means where the item goes to. Order sequence needs to be exactly a permutation of the sequence [0, 1, ... , N], where N is the biggest index in the item sequence (zero-indexed).
Implementations are based on these articles:

https://devblogs.microsoft.com/oldnewthing/20170111-00/?p=95165
The routines come in 2 forms; the first one takes two iterators to define the item range and one iterator to define the beginning of index range. The second form takes range to define the item sequence and range to define index sequence.
[heading interface]
There are two versions of algorithms:
1) takes four iterators.
2) takes two ranges.
``
template<typename RandomAccessIterator1, typename RandomAccessIterator2>
void apply_permutation(RandomAccessIterator1 item_begin, RandomAccessIterator1 item_end,
RandomAccessIterator2 ind_begin, RandomAccessIterator2 ind_end);
template<typename Range1, typename Range2>
void apply_permutation(Range1& item_range, Range2& ind_range);
template<typename RandomAccessIterator1, typename RandomAccessIterator2>
void apply_reverse_permutation(RandomAccessIterator1 item_begin, RandomAccessIterator1 item_end,
RandomAccessIterator2 ind_begin, RandomAccessIterator2 ind_end);

[heading Examples]
Given the containers:

std::vector<int> one{1}, one_order{0},
std::vector<int> two{1,2}, two_order{1,0},
std::vector<int> vec{1, 2, 3, 4, 5},
std::vector<int> order{4, 2, 3, 1, 0}, then
``
apply_permutation(emp_vec, emp_order)) --> no changes
apply_reverse_permutation(emp_vec, emp_order)) --> no changes
apply_permutation(one, one_order) --> no changes
apply_reverse_permutation(one, one_order) --> no changes
apply_permutation(two, two_order) --> two:{2,1}
apply_reverse_permutation(two, two_order) --> two:{2,1}
apply_permutation(vec, order) --> vec:{5, 3, 4, 2, 1}
apply_reverse_permutation(vec, order) --> vec:{5, 4, 2, 3, 1}
``
[heading Iterator Requirements]
`apply_permutation` and 'apply_reverse_permutation' work only on RandomAccess iterators. RandomAccess iterators required both for item and index sequences.
[heading Complexity]
All of the variants of `apply_permutation` and `apply_reverse_permutation` run in ['O(N)] (linear) time.
More
[heading Exception Safety]
All of the variants of `apply_permutation` and `apply_reverse_permutation` take their parameters by iterators or reference, and do not depend upon any global state. Therefore, all the routines in this file provide the strong exception guarantee.
[heading Notes]
* If ItemSequence and IndexSequence are not equal, behavior is undefined.
* `apply_permutation` and `apply_reverse_permutation` work also on empty sequences.
* Order sequence must be zero-indexed.
* Order sequence gets permuted.

The header file 'find_backward.hpp' contains variants of the stl algorithm
`find`. These variants are like `find`, except that the evaluate the elements
of the given sequence in reverse order.
Consider how finding the last element that is equal to `x` in a range is
typically done:
// Assume a valid range if elements delimited by [first, last).
while (last-- != first) {
if (*last == x) {
// Use last here...
}
}
Raw loops are icky though. Perhaps we should do a bit of extra work to allow
the use of `std::find()`:
auto rfirst = std::make_reverse_iterator(last);
auto rlast = std::make_reverse_iterator(first);
auto it = std::find(rfirst, rlast, x);
// Use it here...
That seems nicer in that there is no raw loop, but it has two major drawbacks.
First, it requires an unpleasant amount of typing. Second, it is less
efficient than forward-iterator `find` , since `std::reverse_iterator` calls
its base-iterator's `operator--()` in most of its member functions before
doing the work that the member function requires.

The header file 'find_not.hpp' contains a variants of a the stl algorithm
`find`. The algorithm finds the first value in the given sequence that is not
equal to the given value.
Consider this use of `find()`:
std::vector<int> vec = { 1, 1, 2 };
auto it = std::find(vec.begin(), vec.end(), 1);
This gives us the first occurance of `1` in `vec`. What if we want to find
the first occurrance of any number besides `1` in `vec`? We have to write an
unfortunate amount of code:
std::vector<int> vec = { 1, 1, 2 };
auto it = std::find_if(vec.begin(), vec.end(), [](int i) { return i != 1; });
With `find_not()` the code gets much more terse:
std::vector<int> vec = { 1, 1, 2 };
auto it = find_not(vec.begin(), vec.end(), 1);
The existing `find` variants are: `find()`, `find_if()`, and `find_if_not()`.
It seems natural to also have `find_not()`, for the very reason that we have
`find_if_not()` -- to avoid having to write a lambda to wrap the negation of
the find condition.

These overloads of `find_not` return the first value that is not equal to `x`
in the sequence `[first, last)` or `r`, respectively.
[heading Examples]
Given the container `c1` containing `{ 0, 1, 2 }`, then
find_not ( c1.begin(), c1.end(), 1 ) --> c1.begin()
find_not ( c1.begin(), c1.end(), 0 ) --> std::next(c1.begin())
[heading Iterator Requirements]
`find_not` works on all iterators except output iterators.
The template parameter `Sentinel` is allowed to be different from `InputIter`,
or they may be the same. For an `InputIter` `it` and a `Sentinel` `end`, `it
== end` and `it != end` must be well-formed expressions.
[heading Complexity]
Linear.

The header file 'is_palindrome.hpp' contains six variants of a single algorithm, is_palindrome.
The algorithm tests the sequence and returns true if the sequence is a palindrome; i.e, it is identical when traversed either backwards or frontwards.
The routine `is_palindrome` takes a sequence and, optionally, a predicate. It will return true if the predicate returns true for tested elements by algorithm in the sequence.
The routine come in 6 forms; the first one takes two iterators to define the range. The second form takes two iterators to define the range and a predicate.
The third form takes a single range parameter, and uses Boost.Range to traverse it. The fourth form takes a single range parameter ( uses Boost.Range to traverse it) and a predicate.
The fifth form takes a single C-string and a predicate. The sixth form takes a single C-string.
[heading interface]
The function `is_palindrome` returns true if the predicate returns true any tested by algorithm items in the sequence.
There are six versions:
1) takes two iterators.
2) takes two iterators and a predicate.
3) takes a range.
4) takes a range and a predicate.
5) takes a C-string and a predicate.
6) takes a C-string.
``

template<typename Range, typename Predicate>
bool is_palindrome ( const Range &r, Predicate p );
template<typename Predicate>
bool is_palindrome ( const char* str, Predicate p );
bool is_palindrome(const char* str);
``
[heading Examples]
Given the containers:
const std::list<int> empty,
const std::vector<char> singleElement{'z'},
int oddNonPalindrome[] = {3,2,2},
const int oddPalindrome[] = {1,2,3,2,1},
const int evenPalindrome[] = {1,2,2,1},
int evenNonPalindrome[] = {1,4,8,8}, then
``
is_palindrome(empty)) --> true //empty range
is_palindrome(singleElement)) --> true
is_palindrome(std::begin(oddNonPalindrome), std::end(oddNonPalindrome))) --> false
is_palindrome(std::begin(evenPalindrome), std::end(evenPalindrome))) --> true
is_palindrome(empty.begin(), empty.end(), functorComparator())) --> true //empty range

is_palindrome(std::begin(evenNonPalindrome), std::end(evenNonPalindrome)) --> false
is_palindrome("a") --> true
is_palindrome("aba", std::equal_to<char>()) --> true
``
[heading Iterator Requirements]
`is_palindrome` work on Bidirectional and RandomAccess iterators.
[heading Complexity]
All of the variants of `is_palindrome` run in ['O(N)] (linear) time; that is, they compare against each element in the list once. If any of the comparisons not succeed, the algorithm will terminate immediately, without examining the remaining members of the sequence.
[heading Exception Safety]
All of the variants of `is_palindrome` take their parameters by value, const pointer or const reference, and do not depend upon any global state. Therefore, all the routines in this file provide the strong exception guarantee.
[heading Notes]
* `is_palindrome` returns true for empty ranges, const char* null pointers and for single element ranges.
* If you use version of 'is_palindrome' without custom predicate, 'is_palindrome' uses default 'operator==()' for elements.
* Be careful with using not null pointer 'const char*' without '\0' - if you use it with 'is_palindrome', it's a undefined behaviour.

The header file 'is_partitioned_until.hpp' contains two variants of a single algorithm, `is_partitioned_until`. The algorithm tests to see if a sequence is partitioned according to a predicate; in other words, all the items in the sequence that satisfy the predicate are at the beginning of the sequence.
The routine `is_partitioned_until` takes a sequence and a predicate. It returns the last iterator 'it' in the sequence [begin, end) for which the is_partitioned(begin, it) is true.
`is_partitioned_until` come in two forms; the first one takes two iterators to define the range. The second form takes a single range parameter, and uses Boost.Range to traverse it.

bool lessThan10 ( int i ) { return i < 10; }
is_partitioned_until ( c, isOdd ) --> iterator to '1'
is_partitioned_until ( c, lessThan10 ) --> end
is_partitioned_until ( c.begin (), c.end (), lessThan10 ) --> end
is_partitioned_until ( c.begin (), c.begin () + 3, lessThan10 ) --> end
is_partitioned_until ( c.end (), c.end (), isOdd ) --> end // empty range

``
Each of the functions is passed two pairs of iterators. The first two define the corpus and the second two define the pattern. Note that the two pairs need not be of the same type, but they do need to "point" at the same type. In other words, `patIter::value_type` and `curpusIter::value_type` need to be the same type.
The return value of the function is an iterator pointing to the start of the pattern in the corpus. If the pattern is not found, it returns the end of the corpus (`corpus_last`).
The return value of the function is a pair of iterators pointing to the position of the pattern in the corpus. If the pattern is empty, it returns at empty range at the start of the corpus (`corpus_first`, `corpus_first`). If the pattern is not found, it returns at empty range at the end of the corpus (`corpus_last`, `corpus_last`).
[heading Compatibility Note]
Earlier versions of this searcher returned only a single iterator. As explained in [@https://cplusplusmusings.wordpress.com/2016/02/01/sometimes-you-get-things-wrong/], this was a suboptimal interface choice, and has been changed, starting in the 1.62.0 release. Old code that is expecting a single iterator return value can be updated by replacing the return value of the searcher's `operator ()` with the `.first` field of the pair.
Instead of:
``
iterator foo = searcher(a, b);
``
you now write:
``
iterator foo = searcher(a, b).first;
``
[heading Performance]
The execution time of the Knuth-Morris-Pratt algorithm is linear in the size of the string being searched. Generally the algorithm gets faster as the pattern being searched for becomes longer. Its efficiency derives from the fact that with each unsuccessful attempt to find a match between the search string and the text it is searching, it uses the information gained from that attempt to rule out as many positions of the text as possible where the string cannot match.

An extension to find algorithms is the Find Iterator. Instead of searching for just a one part of a string,
the find iterator allows us to iterate over the substrings matching the specified criteria.
This facility is using the <link linkend="string_algo.finder_concept">Finder</link> to incrementally
search the string.
