* Fixing YAML => KDL conversion with backslash hotkey.
Previously if the hotkey of backslash was used the yaml => kdl
conversion would create a KDL statement like so: `bind "\" {...}`.
That is incorrect kdl syntax since the backslash escapes the following
quote character. A way to get proper KDL is `bind r"\" {...}`. This
commit changes if the old HotKey is a backslash a properly creates KDL
syntax to address the backslash character.
* rustfmt
* server/os_io: Redefine `ServerOsApi` result types
to use `anyhow::Result` instead. This mostly makes the need of custom
`SpawnTerminalError` obsolete (tbd in subsequent commits) and unifies
error handling across the application.
* utils/errors: Implement new `ZellijError` type
to replace any previously defined, isolated custom error types
throughout the application. Currently implements all error variants
found in `SpawnTerminalError`.
In the long term, this will allow zellij to fall back to a single error
type for all application-specific errors, instead of having different
error types per module.
* server/unit/screen: Impl new `ServerOsApi`
with updated `Result`-types.
* server/tab/unit: Impl new `ServerOsApi`
with updated `Result`-types.
* server/os_io: Impl new `ServerOsApi`
with updated `Result`-types.
* utils/ipc: Return `anyhow::Error` in `send`
rather than a `&'static str`, which isn't compatible with
`anyhow::Context`.
* server/tab: Handle `Result` in `resize_pty!`
which is returned due to the changed return types in `ServerOsApi`.
* server/tab: Handle new `Result`s
originating in the change to the `ServerOsApi` trait definition.
* server/screen: Handle new `Result`s
originating in the change to the `ServerOsApi` trait definition.
* server/panes/tiled: Handle new `Result`s
originating in the change to the `ServerOsApi` trait definition.
* server/panes/floating: Handle new `Result`s
originating in the change to the `ServerOsApi` trait definition.
* server/lib: Unwrap on new `Result`s
originating in the change to the `ServerOsApi` trait definition. The
functions here don't return a `Result` yet, this is better left to a
follow-up PR.
* server: Remove `SpawnTerminalError`
and make use of the new `ZellijError` instead. Make use of `anyhow`s
downcast capabilities to restore the underlying original errors where
necessary, as was done previously. This gives us the flexibility to
attach context information to all errors while still allowing us to
handle specific errors in greater detail.
* server/pty: Fix vars broken in rebase
* server/os_io: Remove last `SpawnTerminalError`
* changelog: Add PR #1895
Do not use Config::default()
default() has empty plugins config and that does not work with the default layout.
Use Config::try_from() instead, since it already handles the clean flag.
Also, do not check the clean flag twice, it is already handled in Config::try_from.
