GPUCompilationMessage: linePos property
Limited availability
This feature is not Baseline because it does not work in some of the most widely-used browsers.
Secure context: This feature is available only in secure contexts (HTTPS), in some or all supporting browsers.
Note: This feature is available in Web Workers.
The linePos read-only property of the
GPUCompilationMessage interface is a number representing the position in the code line that the message corresponds to. This could be an exact point, or the start of the relevant substring.
Value
A number.
To be precise, linePos is the number of UTF-16 code units from the beginning of the line to the exact point or start of the relevant substring that the message corresponds to.
Note that:
- If the message corresponds to a substring,
linePosrefers to the first UTF-16 code unit of the substring. - If the message does not correspond to a specific code position (perhaps it refers to the whole of the shader code),
linePoswill be 0. - Values are one-based — a value of 1 refers to the first code unit of the line.
Examples
const shaderModule = device.createShaderModule({
code: shaders,
});
const shaderInfo = await shaderModule.getCompilationInfo();
const firstMessage = shaderInfo.messages[0];
console.log(firstMessage.linePos);
See the main GPUCompilationInfo page for a more detailed example.
