Introducing CMake is an important step in a larger effort to make Zephyr easy to use for application developers working on different platforms with different development environment needs. Simplified, this change retains Kconfig as-is, and replaces all Makefiles with CMakeLists.txt. The DSL-like Make language that KBuild offers is replaced by a set of CMake extentions. These extentions have either provided simple one-to-one translations of KBuild features or introduced new concepts that replace KBuild concepts. This is a breaking change for existing test infrastructure and build scripts that are maintained out-of-tree. But for FW itself, no porting should be necessary. For users that just want to continue their work with minimal disruption the following should suffice: Install CMake 3.8.2+ Port any out-of-tree Makefiles to CMake. Learn the absolute minimum about the new command line interface: $ cd samples/hello_world $ mkdir build && cd build $ cmake -DBOARD=nrf52_pca10040 .. $ cd build $ make PR: zephyrproject-rtos#4692 docs: http://docs.zephyrproject.org/getting_started/getting_started.html Signed-off-by: Sebastian Boe <sebastian.boe@nordicsemi.no> |

.. _console_getline_sample: console_getline() Sample Application #################################### Overview ******** This example shows how to use :cpp:func:`console_getline()` function. Similar to the well-known ANSI C gets() and fgets() functions, :cpp:func:`console_getline()` either returns the next available input line or blocks waiting for one. Using this function, it should be fairly easy to port existing ANSI C, POSIX, or Linux applications which process console input line by line. The sample also allows to see details of how a line is returned by the function. If you are interested in character by character console input, see :ref:`console_getchar_sample`. Requirements ************ UART console is required to run this simple. Building and Running ******************** The easiest way to run this sample is using QEMU: .. code-block:: console $ cd samples/console/getline $ make BOARD=qemu_x86 $ make BOARD=qemu_x86 run Now start pressing keys on a keyboard, followed by Enter. The input line will be printed back, with a hex code of the last character, to show that line does not include any special "end of line" characters (like LF, CR, etc.)
