= Main Command-Line options
|= Option name |= Description |
| --version | Display the version of the compiler |
| -o <file> | Set the output filename to <file> |
| --source-map | Generate sourcemap |
| --opt {1,2,3} | Set the compilation profile
(default 1). See **Optimization**
section below. |
| --pretty | Pretty print javascript output |
| --target-env | Build javascript for the requested
environment (default "isomorphic").
Isomorphic javascript runs in both the
browser & nodejs. "nodejs" & "browser"
options bundle less javascript, but
drop support for APIs incompatible with
the selected runtime. |
| --no-inline | Disable code inlining |
| --debug-info | Output debug information |
| -I dir | Add <dir> to the list of
include directories |
| --file file[:target] | Register <file> to the pseudo filesystem
and choose the destination <target>. The
<target> can be a directory or a file
(default /static/) |
| --enable <option> | Enable option <option> |
| --disable <option> | Disable option <option> |
=Optimizations
* For Debugging: "--pretty --no-inline --debug-info" + eventually "--disable staticeval --disable share"
* For Production: "--opt 3". It minimize the generated javascript by applying
various optimizations until a fix-point is reached
