# Tint style guide
|
|
|
|
* Generally, follow the [Chromium style guide for C++](https://chromium.googlesource.com/chromium/src/+/HEAD/styleguide/c++/c++.md)
|
|
which itself is built on the [Google C++ style guide](https://google.github.io/styleguide/cppguide.html).
|
|
|
|
* Overall try to use the same style and convention as code around your change.
|
|
|
|
* Code must be formatted. Use `clang-format` with the provided [.clang-format](../.clang-format)
|
|
file. The `tools/format` script runs the formatter.
|
|
|
|
* Code should not have linting errors.
|
|
The `tools/lint` script runs the linter. So does `git cl upload`.
|
|
|
|
* Do not use C++ exceptions
|
|
|
|
* Do not use C++ RTTI.
|
|
Instead, use `tint::Castable::As<T>()` from
|
|
[src/castable.h](../src/castable.h)
|
|
|
|
* Generally, avoid `assert`. Instead, issue a [diagnostic](../src/diagnostic.h)
|
|
and fail gracefully, possibly by returning an error sentinel value.
|
|
Code that should not be reachable should call `TINT_UNREACHABLE` macro
|
|
and other internal error conditions should call the `TINT_ICE` macro.
|
|
See [src/debug.h](../src/debug.h)
|
|
|
|
* Use `type` as part of a name only when the name refers to a type
|
|
in WGSL or another shader language processed by Tint. If the concept you are
|
|
trying to name is about distinguishing between alternatives, use `kind` instead.
|
|
|
|
## Compiler support
|
|
|
|
Tint requires C++14.
|
|
|
|
Tint uses the Chromium build system and will stay synchronized with that system.
|
|
Compiler configurations beyond that baseline is on a best-effort basis.
|
|
We strive to support recent GCC and MSVC compilers.
|
|
|
|
## Test code
|
|
|
|
We might relax the above rules rules for test code, since test code
|
|
shouldn't ship to users.
|
|
|
|
However, test code should still be readable and maintainable.
|
|
|
|
For test code, the tradeoff between readability and maintainability
|
|
and other factors is weighted even more strongly toward readability
|
|
and maintainability.
