* utils: re-export "anyhow" unconditionally even for wasm targets. * utils/errors: Share wasm-compatible code and move everything that can't run in wasm into a separate submodule. * utils: Share "errors" module unconditionally The module is now structured such that all code incompatible with wasm targets lives in its own submodule that isn't included when compiling for wasm targets. * utils/errors: Add "Help wanted" doc section that informs the reader about the endeavour to improve error handling throughout the zellij code base. * plugins: Handle errors returned by `zellij_tile` now that the panic calls have been removed. * utils/errors: Extend `anyhow::Result` with traits that allow for easy/concise logging of `anyhow::Result` types and panicking the application when they are fatal or non-fatal. * utils/errors: Fix doctest * utils/errors: Add prelude that applications can import to conveniently access the error handling functionality part of the module. Re-exports some parts and macros from anyhow and the `LoggableError` and `FatalError` traits. * server/screen: Adopt error handling and make all fallible functions from the public API return a `Result`. Append error contexts in all functions that can come across error types to allow tracing where an error originates and what lead there. * server/lib: Catch errors from `screen` and make them `fatal`. This will log the errors first, before unwrapping on the error type and panicking the application. * server/unit/screen: Fix unit tests and unwrap on the `Result` types introduced from the new error handling. * utils/errors: Track error source in calls to `fatal`, so we keep track of the location where the panic really originates. Otherwise, any call to `fatal` will show the code in `errors` as source, which of course isn't true. Also change the error formatting and do not call `to_log` for fatal errors anymore, because the panic is already logged and contains much more information. * utils/errors: Update `FatalError` docs * plugins: Undo accidental modifications * utils/errors: Improve module docs explain some error handling facilities and the motivation behind using them. * server/screen: Remove `Result` from Infallible functions that are part of the public API. |
