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.dllYou 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.
