GPUCompilationMessage: lineNum property
Limited availability
This feature is not Baseline because it does not work in some of the most widely-used browsers.
Experimental: This is an experimental technology
Check the Browser compatibility table carefully before using this in production.
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 lineNum
read-only property of the
GPUCompilationMessage
interface is a number representing the line number in the shader code that the message corresponds to.
Value
A number.
Note that:
- If the message corresponds to a substring,
lineNum
refers to the line number that the substring begins on. - If the message does not correspond to a specific line of code (perhaps it refers to the whole of the shader code),
lineNum
will be 0. - Values are one-based — a value of 1 refers to the first line of code.
- Lines are delimited by line breaks. In WGSL, a specific list of characters is defined as line breaks.
Examples
js
// ...
const shaderModule = device.createShaderModule({
code: shaders,
});
const shaderInfo = await shaderModule.getCompilationInfo();
const firstMessage = shaderInfo.messages[0];
console.log(firstMessage.lineNum);
// ...
}
See the main GPUCompilationInfo
page for a more detailed example.
