Native libsass plugin adding trigonometric and mathematical functions.
You need to have libsass already compiled or installed as a shared library (inclusive header files). It is then compiled via cmake
. See this example to compile it on windows via MinGW Compiler Suite:
git clone https://github.com/sass/libsass.git mingw32-make -C libsass BUILD=shared CC=gcc -j5 git clone https://github.com/mgreter/libsass-math.git cd libsass-math && mkdir build && cd build cmake -G "MinGW Makefiles" .. -DLIBSASS_DIR="..\..\libsass" mingw32-make CC=gcc -j5 && dir math.dll
You may define LIBSASS_INCLUDE_DIR
and LIBSASS_LIBRARY_DIR
separately!
The following globals are available when you import the math plugin.
$E
- Euler's number (used for the natural logarithm).$PI
- The ratio of a circle's circumference to its diameter.$TAU
- The double of pi, because Pi is wrong.The following functions are available when you import the math plugin.
