class TShader

Defined at line 465 of file ../../third_party/glslang/src/glslang/Public/ShaderLang.h

Make one TShader per shader that you will link into a program. Then

- provide the shader through setStrings() or setStringsWithLengths()

- optionally call setEnv*(), see below for more detail

- optionally use setPreamble() to set a special shader string that will be

processed before all others but won't affect the validity of #version

- optionally call addProcesses() for each setting/transform,

see comment for class TProcesses

- call parse(): source language and target environment must be selected

either by correct setting of EShMessages sent to parse(), or by

explicitly calling setEnv*()

- query the info logs

N.B.: Does not yet support having the same TShader instance being linked into

multiple programs.

N.B.: Destruct a linked program *before* destructing the shaders linked into it.

void setEnvInput (EShSource lang, EShLanguage envStage, EShClient client, int version)

For setting up the environment (cleared to nothingness in the constructor).

These must be called so that parsing is done for the right source language and

target environment, either indirectly through TranslateEnvironment() based on

EShMessages et. al., or directly by the user.

setEnvInput: The input source language and stage. If generating code for a

specific client, the input client semantics to use and the

version of that client's input semantics to use, otherwise

use EShClientNone and version of 0, e.g. for validation mode.

Note 'version' does not describe the target environment,

just the version of the source dialect to compile under.

For example, to choose the Vulkan dialect of GLSL defined by

version 100 of the KHR_vulkan_glsl extension: lang = EShSourceGlsl,

dialect = EShClientVulkan, and version = 100.

See the definitions of TEnvironment, EShSource, EShLanguage,

and EShClient for choices and more detail.

setEnvClient: The client that will be hosting the execution, and its version.

Note 'version' is not the version of the languages involved, but

the version of the client environment.

Use EShClientNone and version of 0 if there is no client, e.g.

for validation mode.

See EShTargetClientVersion for choices.

setEnvTarget: The language to translate to when generating code, and that

language's version.

Use EShTargetNone and version of 0 if there is no client, e.g.

for validation mode.

bool parse (const TBuiltInResource * builtInResources, int defaultVersion, bool forwardCompatible, EShMessages messages)

Equivalent to parse() without a default profile and without forcing defaults.
