+
+*** C++ Header Tools
+
+A collection of C++ (mostly, C++11) header-only utility libraries.
+
+**** Examples
+
+Below you can find code snippets. For full examples and some tests, see the [[examples]] folder. In some cases, sample programs are included in the header files themselves, and they can be enabled by specific CPP defines.
+
+***** logger
+
+A thread-safe facility-based logging mechanism.
+
+#+BEGIN_EXAMPLE
+#include "logger.hpp"
+...
+logger::Logger::set_default_level("info");
+int c = 0;
+LOG(info) << "now you see me; c=" << ++c << "\n";
+assert(c == 1);
+LOG(debug) << "now you don't; c=" << ++c << "\n";
+assert(c == 1);
+#+END_EXAMPLE
+
+***** zstr
+
+A ZLib wrapper.
+
+#+BEGIN_EXAMPLE
+#include "zstr.hpp"
+...
+zstr::ifstream(argv[1]) >> i;
+#+END_EXAMPLE
+
+***** alg
+
+Collection of new and extended SL algorithms. Contents:
+
+- =for_each[_it][_advance]=: Apply functor to elements in range. Options: take iterator pair or range as input; pass iterator instead of element to functor; store next iterator prior to applying functor (e.g. use: remove elements from a list in one pass.)
+
+- =(min|max|minmax)[_value]_of=: Find min and/or max in range. Options: take iterator pair or range as input; optionally use functor to extract key; return iterator or value.
+
+- =mean_stdv_of=: Find mean and sample stdv of elements in range. Options: take iterator pair or range as input; optionally use functor to extract key.
+
+- =(equal|all|any)_of=: Check range of elements are equal, or that all are true, or that at least one is true. Options: take iterator pair or range as input; optionally use functor to extract key.
+
+- =os_join=: Use =operator <<= overloads to print range or to convert it to string using a custom separator. Options: take iterator pair or range as input; optionally use functor to extract key.
+
+#+BEGIN_EXAMPLE
+#include "alg.hpp"
+...
+std::vector< int > v{3, 6, 18};
+bool equal_mod_3 = alg::equal_of(v, [] (int i) { return i%3; }); // true
+std::cout << "v: " << alg::os_join(v, ", ") << std::endl; // prints "v: 3, 6, 18"
+#+END_EXAMPLE
+
+***** logsum
+
+Floating point additions in logarithmic space using table lookup.
+
+*Note*: This library is based on Sean Eddy's code, originall part of HMMER. The version included in here is header-only, and it using implicit table initialization (no need to explicitly call =p7_FLogsumInit()=).
+
+#+BEGIN_EXAMPLE
+#include "logsum.hpp"
+...
+float r = p7_FLogsum(.5, .3); // ~= log(exp(.5) + exp(.3))
+#+END_EXAMPLE
+
+***** pfor
+
+A C++11-based parallel for, with optional output sorting.
+
+#+BEGIN_EXAMPLE
+#include "pfor.hpp"
+...
+std::vector< unsigned > v(1000);
+unsigned crt_idx = 0;
+pfor::pfor< unsigned >(
+ 4, // num_threads
+ 10, // chunk_size
+ [&] (unsigned& i) // get_item
+ {
+ if (crt_idx >= v.size()) return false;
+ i = crt_idx++; return true;
+ },
+ [&] (unsigned& i) // process_item
+ {
+ v[i] = i*i;
+ });
+#+END_EXAMPLE
+
+***** tpool
+
+A C++11-based thread pool.
+
+#+BEGIN_EXAMPLE
+#include "tpool.hpp"
+...
+void some_work(unsigned tid, unsigned i);
+...
+// create a pool of 4 worker threads
+tpool::tpool p(4);
+// perform 10 rounds of work
+for (int unsigned = 0; round < 10; ++round)
+{
+ // in each round, work on n items
+ for (unsigned i = 0; i < n; i += 2)
+ {
+ p.add_job(std::bind(some_work, std::placeholders::_1, i));
+ // Note: the lambda must capture i by value, not by reference
+ p.add_job([&,i] (unsigned tid) { some_work(tid, i + 1); });
+ }
+ p.wait_jobs();
+}

+///
+/// Logger mechanism.
+///
+/// Properties:
+/// - thread-safe, non-garbled output (uses c++11's thread_local)
+/// - customizable ostream sink. by default, uses std::clog
+///
+/// Exports:
+/// - "LOG" macro (takes 1, 2, or 3 arguments, see below)
+/// - "logger" namespace
+/// - "logger::level" enum
+/// - "logger::Logger" class
+///
+/// To use:
+/// - In source code, use:
+///
+/// LOG(info) << "hello" << endl;
+/// // or
+/// LOG("main", info) << "hello" << endl;
+/// // or
+/// LOG("main", info, sink_os) << "hello" << endl;
+///
+/// Here, "main" is the facility (a string) and info is the message level.
+/// Note that "logger" is a macro which knows how to look up the name info
+/// inside logger namespace. The macro introduces C++ code equivalent to:
+///
+/// if (...message should be ignored...) then; else sink_os
+///
+/// NOTE: As with assert(), the code in the output stream following the
+/// LOG() macro will ***not be executed*** if the log level of the
+/// facility is higher than the level of the message.
+///
+/// - To set the default log level (for unspecified facilities):
+///
+/// logger::Logger::set_default_level(logger::Logger::level_from_string(s));
+///
+/// - To set the log level for the "main" facility:
+///
+/// logger::Logger::set_facility_level("main", logger::Logger::level_from_string(s));
+///
+/// - To parse a log facility level setting in the form "[<facility>:]<level>":
+///
+/// logger::Logger::set_level_from_option("alt:debug1", &cerr);
+///
+/// - By using these functions, one can set log levels using command-line
+/// parameters and achieve dynamic log level settings without recompiling.

+/* p7_FLogsum() function used in the Forward() algorithm.
+ *
+ * Contents:
+ * 1. Floating point log sum.
+ * 2. Benchmark driver.
+ * 3. Unit tests.
+ * 4. Test driver.
+ * 5. Example.
+ * 6. Copyright and license information.
+ *
+ * Exegesis:
+ *
+ * Internally, HMMER3 profile scores are in nats: floating point
+ * log-odds probabilities, with the log odds taken relative to
+ * background residue frequencies, and the log to the base e.
+ *
+ * The Forward algorithm needs to calculate sums of probabilities.
+ * Given two log probabilities A and B, where s1 = \log
+ * \frac{a}{f}, and s2 = \log \frac{b}{g}, we need to
+ * calculate C = \log \frac{a + b}{h}.
+ *
+ * The Forward algorithm guarantees that the null model denominator
+ * terms f = g = h, because it is always concerned with summing terms
+ * that describe different parses of the same target sequence prefix,
+ * and the product of the background frequencies for the same sequence
+ * prefix is a constant.
+ *
+ * The naive solution is C = log(e^{A} + e^{B}), but this requires
+ * expensive calls to log() and exp().
+ *
+ * A better solution is C = A + log(1 + e^{-(A-B)}), for A >= B. For
+ * sufficiently small B << A, e^-{A-B} becomes less than the
+ * machine's FLT_EPSILON, and C ~= A. (This is at about (A-B) >
+ * -15.9, for the typical FLT_EPSILON of 1.2e-7.)
+ *
+ * With some loss of accuracy [1], we can precalculate log(1 +
+ * e^{-(A-B)}) for a discretized range of differences (A-B), and
+ * compute C = A + table_lookup(A-B). This is what HMMER's
+ * p7_FLogsum() function does.
+ *
+ * This only applies to the generic (serial) implementation.
+ * See footnote [2] for discussion of why we remain unable to
+ * implement an efficient log-space SIMD vector implementation of
+ * Forward.

+///
+/// Given a number of threads and a chunk size, the total work is split into
+/// chunks, each chunk is processed independently by a thread. Optionally, the
+/// outputs can be reordered in the same order they were read. More
+/// specifically:
+/// - The master thread starts `num_threads` worker threads, then waits for
+/// all workers. Each worker proceeds as follows:
+/// - Allocate a vector of `chunk_size` objects of type `Input` which are
+/// default-initialized.
+/// - Execute `do_before()`.
+/// - Repeatedly, until done:
+/// - Inside an input critical section: call `get_item()` repeatedly,
+/// getting up to `chunk_size` items. The `get_item()` function should
+/// save an item in the `Input` location given as parameter.
+/// - If `Chunk_Output` is given:
+/// - Allocate a new default-initialized Chunk_Output object on the heap.
+/// - Repeatedly call `process_item()` in the order the items appear in the
+/// thread local buffer. If `Chunk_Output` is given, the calls are passed
+/// the same `Chunk_Output` object.
+/// - If `Chunk_Output` is given: Inside an output critical section, the
+/// `Chunk_Output` object is added to a heap. As long as the chunk that
+/// must be output next is in found in the heap, `output_chunk` is called
+/// on that object, after which it is destroyed.
+/// - Execute `do_after()`.
+///
+/// To ENABLE output sorting:
+/// - `Chunk_Output` should contain one (or more) ostringstream object(s);
+/// - `process_item()` should take 2 arguments, the second being a
+/// `Chunk_Output` object; the ostringstream inside that `Chunk_Output` should
+/// be used for output inside `process_item()`;
+/// - `output_chunk()` should flush the ostringstream to output.
+///
+/// To DISABLE output sorting:
+/// - `Chunk_Output` should not be specified;
+/// - `process_item()` should take 1 argument only;
+/// - `output_chunk()` should not be specified.
+///
+/// @tparam Input Type of the input items.
+/// @tparam Chunk_Output (optional) Type of an object created during the
+/// processing of each chunk. Each such object is tagged with its chunk number,
+/// and placed in a priority queue. The objects are destroyed inside an output
+/// critical section in the order of their chunk numbers.
+/// @param num_threads Number of worker threads to spawn.
+/// @param chunk_size Number of items each thread should process in one chunk.
+/// @param get_item Function executed inside an input critical section. If an
+/// item is available, the function should save it in the `Input` location given
+/// as parameter, and return true. If the items have been exhausted, the
+/// function should return false.
+/// @param process_item Function executed to process the given `Input` item. If
+/// output sorting is enabled, the function takes as second argument a
+/// `Chunk_Output` object that will be the same for all items in that chunk.
+/// @param output_chunk (optional) Function called on a `Chunk_Output`
+/// object inside an output critical section before it is destroyed.
+/// @param do_before Function executed by each thread before any actual work.
+/// @param do_after Function executed by each thread after all work.
+/// @progress_report Function that will be called to report progress with 2
+/// arguments: the number of items processed, and the number of seconds
+/// elapsed so far.
+/// @progress_count Number of items that should be processed between calls to
+/// `progress_report`. (This will be rounded down to be divisible by
+/// `chunk_size`).
