Compile from the Command-Line
$ gcss /path/to/gcss/file
or
$ cat /path/to/gcss/file | gcss > /path/to/css/file
Compile from Go programs
You can compile a GCSS file from Go programs by invoking the gcss.CompileFile function.
cssPath, err := gcss.CompileFile("path_to_gcss_file")
if err != nil {
http.Error(w, err.Error(), http.StatusInternalServerError)
return
}
http.ServeFile(w, r, cssPath)
You can invoke the gcss.Compile function instead of the gcss.CompileFile function. The gcss.Compile function takes io.Writer and io.Reader as a parameter, compiles the GCSS data which is read from the io.Reader and writes the result CSS data to the io.Writer. Please see the GoDoc for the details.
f, err := os.Open("path_to_gcss_file")
if err != nil {
panic(err)
}
defer func() {
if err := f.Close(); err != nil {
panic(err)
}
}()
n, err := gcss.Compile(os.Stdout, f)
