Release_2_0

Features:

• Complete rewrite of the UI and upgrade to .NET 7.0, adding support for OS X (ARM M1/M2).
• Allow in-place editing of the source GLSL.
• Recycle output GLSL back to the source pane.
• Revamp the Hint and Tips feature.

GLSL Shader Shrinker v0.19-alpha

Features:

• Dot products with two constant vectors (or one with a single unit value) are simplified.
  E.g.
  "f = dot(vec2(1, 2), vec2(3,4))" => "f = 11.0"
  "f = dot(vec2(0, 1), v)" => "f = v.y"

Bug Fixes:

• Prevent 'uniform' variables having their names GOLFed.
• Fix golfing name starting with underscore to single character.
• Hint was incorrectly suggesting 'mainImage()' could be inlined.

GLSL Shader Shrinker v0.18-alpha

Features:

• Experimental support for code GOLFing.
• Last-used Shadertoy ID now remembered.
• Full Shadertoy shader paths now supported during import.
  Custom options dialog can now load from predefined 'preset' files.

Bug Fixes:

• Deep if/else statements could cause incorrect use of braces.

GLSL Shader Shrinker v0.17-alpha

Features:

• Support output to C-style strings
• Custom options dialog can now load from predefined 'preset' files.

Bug Fixes:

• Unable to perform vector arithmetic when one side has multi-value expression.

Other:

• Removing a function will now also remove its preceding comment.
• Include the one-click publisher settings.

GLSL Shader Shrinker v0.16-alpha

Features:

• This installer hosts a self-contained single-file x64 version of the app, hopefully avoiding the need for users to install and .NET runtimes.

Bug Fixes:

• Prevent inlining a const variable if a child variable with the same name exists.
• Don't make variables const if modified using array accessor.
• Replacing function call with its 'return' value was failing for vector arguments.

GLSL Shader Shrinker v0.15-alpha

Features:

• Even more cases where math results can be precalculated:
  clamp, length, normalize, floor, ceil, trunc, and fract.

GLSL Shader Shrinker v0.14-alpha

Features:

• Hint when calls to a function all use the same constant parameter.
• Attempt to move a parameter into the function definition if all callers pass the same value.
• Simplify single-element vector to float if used in further vector arithmetic.
• Pre-calculate the results of a vector and vector.
• Pre-calculate the results of a float and vector.
• Pre-calculate simple 'sign(...)' expressions.
• Detect more cases where simple math can be evaluated.

GLSL Shader Shrinker v0.13-alpha

Bug Fixes:

• Allow parsing of function definitions containing params with no param names. (E.g. 'void myFunc(int, int);')
• Prevent inlining const arrays.
• Avoid spurious code changes during 'shrink'. (Modifying an inlined constant would modify all other inlined instances.)

GLSL Shader Shrinker v0.12-alpha

Features:

• New hint - Detect function calls that may be replaced with a constant.
• New optimization - Replace function calls that can be replaced with a constant.

GLSL Shader Shrinker v0.11-alpha

Features:

• More post-optimizing code GOLFing 'hints'.
• More math functions which can have their values precalculated (sin, cos, tan, asin, acos, atan, radians, degrees).
  E,g.
  float segments = 10; float angle = sin(3.14159 * 2.0 / segments);
  simplifies to
  float angle = 0.58778;
