* Use QList instead of QVector in gui testsJarek Kobus2020-06-251-1/+2

* QShaderGenerator: Allow more expressions in input nodesNicolas Guichard2020-02-201-0/+50
| | | | | | | | | | | | | | | | | | Currently QShaderGenerator will crash when encountering some expressions in input nodes. For example, this node prototype would make it crash: "VERTEX_COLOR": { "outputs": ["color", "alpha"], "rules": [ "headerSnippets": ["in vec4 vertexColor;"], "substitution": "vec3 $color = vertexColor.rgb; float $alpha = vertexColor.a;" ] } Change-Id: I37abb8099d376843a4cb13228140467dc1b8f60c Reviewed-by: Paul Lemire <paul.lemire@kdab.com>
* QShaderGenerator: Don't crash when a node has multiple outputsNicolas Guichard2020-02-201-0/+73
| | | | | | | | | | | | | | | | | | | | | | It was already possible to declare a node prototype with multiple outputs, but trying to assign to all those outputs was not possible and instead resulted in a crash. It is now possible to declare nodes like this without crashing: "SEPERATE_XYZ": { "inputs": ["vector"], "outputs": ["x", "y", "z"], "rules": [ { "substitution": "float $x = $vector.x; float $y = $vector.y; float $z = $vector.z;" } ] } Change-Id: I748e77e84c9120dc688c573eee33dc13c6bfbace Reviewed-by: Paul Lemire <paul.lemire@kdab.com>
* Fix QShaderGenerator crashing when a node port name prefixed another oneNicolas Guichard2020-02-191-0/+70
| | | | | | | | | | | | | | QShaderGenerator didn't handle substitutions like `vec4 $color = mix($color1, $color2, $fac);` Note that `$color` is a prefix to `$color1` and `$color2`. For the substitution `QByteArray::replace` was used so if `$color` was handled first and replaced by `v1`, `$color1` and `$color2` were never correctly replaced and instead became `v11` and `v12` which caused a crash later on.

* Only generate temporaries when it makes sensePaul Lemire2019-05-021-31/+183
| | | | | | | | | | | - Never for global inputs - Otherwise only if the temporary is referenced more than once -> meaning it's actually caching the result of some operation Tests updated accordingly.

* QShaderGenerator: don't generate temporary variables for global inputsPaul Lemire2019-04-101-40/+146
| | | | | | | | | Up until now, the QShaderGenerator would create temporary variables for uniform, attributes, const. This change makes it use the global inputs directly rather than relying on the intermediate properties.
