+# About
+Lightweight cross-platform profiler library for c++
+
+You can profile any function in you code. Furthermore this library provide measuring time of any block of code.
+For example, information for 12 millions of blocks is using less than 300Mb of memory.
+Working profiler slows your application execution for only 1-2%.
+
+![Block time](https://hsto.org/files/3e4/afe/8b7/3e4afe8b77ac4ad3a6f8c805be4b7f13.png)
+_Average overhead per block is about 15ns/block (tested on Intel Core i7-5930K 3.5GHz, Win7)_
+
+Disabled profiler will not affect your application execution in any way. You can leave it in your Release build
+and enable it at run-time at any moment during application launch to see what is happening at the moment.
+
+Also the library can capture system's context switch events between threads. Context switch information includes
+duration, target thread id, thread owner process id, thread owner process name.
+
+You can see the results of measuring in simple GUI application which provides full statistics and renders beautiful time-line.
+
+![GUI screenshot](https://cloud.githubusercontent.com/assets/1775230/24852044/a0b1edd0-1dde-11e7-8736-7052b840ad06.png)
+_Profiling CryEngine SDK example_
+
+# Key features
+
+- Extremely low overhead
+- Low additional memory usage
+- Cross-platform
+- Measuring over network
+- Capture thread context-switch events
+- Fully remove integration via defines
+- GUI could be connected to an application which is already profiling (so you can profile initialization of your application)
+- Monitor main thread fps at real-time in GUI even if profiling is disabled or draw your own HUD/fps-plot directly in your application using data provided by profiler 
+- Configurable timer type with CMakeLists or defines 
+
+# Usage
+
+## Prepare build system
+
+### General
+
+First of all you can specify path to include directory which contains `include/profiler` directory and define macro `BUILD_WITH_EASY_PROFILER`.
+For linking with easy_profiler you can specify path to library.
+
+### Build with cmake
+
+If you are using `cmake` set `CMAKE_PREFIX_PATH` to `lib/cmake/easy_profiler` directory (from [release](https://github.com/yse/easy_profiler/releases) package) and use function `find_package(easy_profiler)` with `target_link_libraries(... easy_profiler)`. Example:
+
+``` cmake
+project(app_for_profiling)
+
+set(SOURCES
+    main.cpp
+)
+
+#CMAKE_PREFIX_PATH should be set to <easy_profiler-release_dir>/lib/cmake/easy_profiler
+find_package(easy_profiler REQUIRED)
+
+add_executable(app_for_profiling ${SOURCES})
+
+target_link_libraries(app_for_profiling easy_profiler)
+```
+
+## Add profiling blocks
+
+Example of usage.
+
+This code snippet will generate block with function name and Magenta color:
+```cpp
+#include <easy/profiler.h>
+
+void frame() {
+    EASY_FUNCTION(profiler::colors::Magenta); // Magenta block with name "frame"
+    prepareRender();
+    calculatePhysics();
+}
+```
+
+To profile any block you may do this as following.
+You can specify these blocks also with Google material design colors or just set name of the block
+(in this case it will have default color which is `Amber100`):
+```cpp
+#include <easy/profiler.h>
+
+void foo() {
+    // some code
+    EASY_BLOCK("Calculating sum"); // Block with default color
+    int sum = 0;
+    for (int i = 0; i < 10; ++i) {
+        EASY_BLOCK("Addition", profiler::colors::Red); // Scoped red block (no EASY_END_BLOCK needed)
+        sum += i;
+    }
+    EASY_END_BLOCK; // This ends "Calculating sum" block
+
+    EASY_BLOCK("Calculating multiplication", profiler::colors::Blue500); // Blue block
+    int mul = 1;
+    for (int i = 1; i < 11; ++i)
+        mul *= i;
+    //EASY_END_BLOCK; // This is not needed because all blocks are ended on destructor when closing braces met
+}
+```
+
+You can also use your own colors. easy_profiler is using standard 32-bit ARGB color format.
+Example:
+```cpp
+#include <easy/profiler.h>
+
+void bar() {
+    EASY_FUNCTION(0xfff080aa); // Function block with custom color
+    // some code
+}
+```
+## Collect blocks
+
+There are two ways to cature blocks
+
+### Collect via network
+
+It's most prefered and convenient approach in many case.
+
+1. Initialize listening by `profiler::startListen()`. It's start new thread to listen on `28077` port the start-capture-signal from gui-application.
+2. To stop listening you can call `profiler::stopListen()` function. 
+
+### Collect via file
+
+1. Enable profiler by `EASY_PROFILER_ENABLE` macro
+2. Dump blocks to file in any place you want by `profiler::dumpBlocksToFile("test_profile.prof")` function
+
+Example:
+```cpp
+int main()
+{
+    EASY_PROFILER_ENABLE;
+    /* do work*/
+    profiler::dumpBlocksToFile("test_profile.prof");
+}
+```
+
+### Note about context-switch
+
+To capture a thread context-switch event you need:
+
+- On Windows: run profiling application "as administrator"
+- On linux: you can run special `systemtap` script with root privileges as follow (example on Fedora):
+```bash
+#stap -o /tmp/cs_profiling_info.log scripts/context_switch_logger.stp name APPLICATION_NAME
+```
+APPLICATION_NAME - name of profiling application
+
+# Build
+
+## Prerequisites
+
+For core:
+* compiler with c++11 support
+* cmake 3.0 or higher
+
+For GUI:
+* Qt 5.3.0 or higher
+
+## Linux
+
+```bash
+$ mkdir build
+$ cd build
+$ cmake ..
+$ make
+```
+
+## Windows
+
+If you are using QtCreator IDE you can just open `CMakeLists.txt` file in root directory.
+If you are using Visual Studio you can generate solution by cmake generator command.
+Examples shows how to generate Win64 solution for Visual Studio 2013. To generate for another version use proper cmake generator (-G "name of generator").
+
+### Way 1
+Specify path to cmake scripts in Qt5 dir (usually in lib/cmake subdir) and execute cmake generator command,
+for example:
+```batch
+$ mkdir build
+$ cd build
+$ cmake -DCMAKE_PREFIX_PATH="C:\Qt\5.3\msvc2013_64\lib\cmake" .. -G "Visual Studio 12 2013 Win64"
+```
+
+### Way 2
+Create system variable "Qt5Widgets_DIR" and set it's value to "[path-to-Qt5-binaries]\lib\cmake\Qt5Widgets".
+For example, "C:\Qt\5.3\msvc2013_64\lib\cmake\Qt5Widgets".
+And then run cmake generator as follows:
+```batch
+$ mkdir build
+$ cd build
+$ cmake .. -G "Visual Studio 12 2013 Win64"
+```

+
+      "Source" form shall mean the preferred form for making modifications,
+      including but not limited to software source code, documentation
+      source, and configuration files.
+
+      "Object" form shall mean any form resulting from mechanical
+      transformation or translation of a Source form, including but
+      not limited to compiled object code, generated documentation,
+      and conversions to other media types.
+
+      "Work" shall mean the work of authorship, whether in Source or
+      Object form, made available under the License, as indicated by a
+      copyright notice that is included in or attached to the work
+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain
+      separable from, or merely link (or bind by name) to the interfaces of,
+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including
+      the original version of the Work and any modifications or additions
+      to that Work or Derivative Works thereof, that is intentionally
+      submitted to Licensor for inclusion in the Work by the copyright owner
+      or by an individual or Legal Entity authorized to submit on behalf of
+      the copyright owner. For the purposes of this definition, "submitted"
+      means any form of electronic, verbal, or written communication sent

+      communication on electronic mailing lists, source code control systems,
+      and issue tracking systems that are managed by, or on behalf of, the
+      Licensor for the purpose of discussing and improving the Work, but
+      excluding communication that is conspicuously marked or otherwise
+      designated in writing by the copyright owner as "Not a Contribution."
+
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and
+      subsequently incorporated within the Work.
+
+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,
+      where such license applies only to those patent claims licensable
+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
