filament material tools

## NAME

glslminifier - filament material tools

## DESCRIPTION

glslminifier minifies GLSL shader code by removing comments, blank lines and indentation.

### Usage:

-

  glslminifier \[options\] \<input file\>

## OPTIONS

**--help**, **-h**

-

  Print this message.

**--license**, **-L**

-

  Print copyright and license information.

**--output**, **-o**

-

  Specify path to output file. If none provided, writes to stdout.

**--optimization**, **-O** \[none\]

-

  Set the level of optimization. "none" performs a simple passthrough.

**--line**, **-l** \[name\]

-

  Insert a #line directive on the first line of the shader with the given name. For example, **--line** foobar.h will insert the following:

-

  \#if defined(GL\_GOOGLE\_cpp\_style\_line\_directive) #line 0 "foobar.h" #endif

-

  This option is meant to be used with **-Onone** optimization.

### Example:

-

  glslminifier **-o** output.fs.min input.fs \> Output file: output.fs.min
