* server/wasm_vm: Compact module imports
* utils/errors: Impl `to_anyhow` for PoisonError
which is returned by calls to `lock` on various types of locks from
`std`. In our case, some of the locks we try to acquire in `wasm_vm` can
contain an `mpsc::Sender`, which is `!Send` and hence doesn't work with
`anyhow`. Turn the `PoisonError` into an error string instead and
returns that as `anyhow::Err`.
* wasm_vm: Remove calls to `unwrap`
in the WASM VM codes server API. Note that this doesn't include the
Plugin APIs. Mark the error as `fatal` in `server/lib`, where the wasm
thread is created.
This will cause zellij to report a proper error (and log it) when any of
the plugin-related functions fails. Unfortunately, this closes the
channel to the WASM thread. Hence, when loading the plugins upon startup
fails, the error reported in the terminal (visible to the user) hints
towards a call in `plugin_pane` being the culprit. However, the real
error will be contained in the logs.
Also add an error message and print it to the user in case that the
plugin failure was caused by a plugin version mismatch.
* server/wasm_vm: Restore panic on failure to load
plugins.
* server/wasm_vm: Add fix to plugin mismatch error
* server/panes/plugin_pane: Hint to logs
when failing to receive a message from the plugins for rendering pane
contents.
* docs: Describe how to handle Options as errors
* CONTRIBUTING: Add tips for code contributions
which will be home to condensed tips and best-practices around the
zellij code. Currently explains to prefer returning `Result` types
instead of `unwrap`ing on them.
The tips in here are meant to be short, concise guides that allow the
user to get started without a lot of reading. The individual tips can
(and should) be supplemented with links to "further reading" where the
topic at hand is explained in greater detail.
* feat(cli): move command to the end of the cli arguments
* feat(cli): allow naming panes from the command line
* fix(cli): adjust actions after pane rename
* feat(cli): zellij run completions for fish
* feat(cli): zellij run completions for bash and zsh
* style(fmt): rustfmt
* fix(e2e): fix run test and snapshot
* style(fmt): rustfmt
* zellij: Add global `DEBUG_MODE` variable
that tells us whether zellij was started with the `--debug` CLI flag.
* utils/errors: Only log thread_bus message in debug
mode, and discard the message otherwise.
* utils/logging: Increase logsize to 16 MiB
per logfile, totaling 32 MiB of logs at most (in two files).
* zellij: Set global `DEBUG` variable in server
thread and make sure the value of the `--debug` CLI flag is propagated
to the server, too.
This means that to enable debug mode, the server must be started with
the `--debug` flag. This happens when the first client that starts the
zellij session has the `--debug` flag set, because it will be forwarded
to the server. Subsequent clients attaching to the same session with the
`--debug` flag specified **do not** override the value of the `DEBUG`
variable. Hence, if the server wasn't started in debug mode, this cannot
be changed.
* feat(layouts): allow defining a global cwd
* feat(layouts): allow passing global cwd from cli

* fix(layouts): error on non-bare children node
* refactor(layout): consolidate split direction parsing
* refactor(layout): remove unused import
* fix(layouts): log error when there is no room for layout
* fix(layout): error on size 0
* feat(layouts): allow pane templates to override template command attributes
* style(fmt): rustfmt
* zellij/commands: Prevent recursive sessions
with session names specified in layout files. A "recursive session" is
created when, while running inside some zellij session, a user attempts
to spawn zellij and make it attach to that same session.
When attaching via CLI (`zellij attach`) we explicitly check for this
condition and error out when needed.
However, besides `zellij attach` it is also possible to declare the
session to attach to in layout files like so:
```yaml
session:
name: "foo"
```
This takes a different codepath when starting zellij, and hence bypases
the checks we already have in place to avoid recursive sessions. Hence,
we implement the check in the other codepath, too, and prevent recursive
sessions from happening for good.

* utils/errors: Add `ToAnyhow` trait
for converting `Result` types that don't satisfy `anyhow`s trait
constraints (`Display + Send + Sync + 'static`) conveniently.
An example of such a Result is the `SendError` returned from
`send_to_plugins`, which sends `PluginInstruction`s as message type.
One of the enum variants can contain a `mpsc::Sender`, which is `!Sync`
and hence makes the whole `SendError` be `!Sync` in this case. Add an
implementation for this case that takes the message and converts it into
an error containing the message formatted as string, with the additional
`ErrorContext` as anyhow context.
* server/tab: Remove calls to `unwrap()`
and apply error reporting via `anyhow` instead. Make all relevant
functions return `Result`s where previously a panic could occur and
attach error context.
* server/screen: Modify `update_tab!`
to accept an optional 4th parameter, a literal "?". If present, this
will append a `?` to the given closure verbatim to handle/propagate
errors from within the generated macro code.
* server/screen: Handle new `Result`s from `Tab`
and apply appropriate error context and propagate errors further up.
* server/tab/unit: `unwrap` on new `Result`s
* server/unit: Unwrap `Results` in screen tests
* server/tab: Better message for ad-hoc errors
created with `anyhow!`. Since these errors don't have an underlying
cause, we describe the cause in the macro instead and then attach the
error context as usual before `?`ing the error back up.
* utils/cargo: Activate `anyhow`s "backtrace" feature
to capture error backtraces at the error origins (i.e. where we first
receive an error and convert it to a `anyhow::Error`). Since we
propagate error back up the call stack now, the place where we `unwrap`
on errors doesn't match the place where the error originated. Hence, the
callstack, too, is quite misleading since it contains barely any
references of the functions that triggered the error.
As a consequence, we have 2 backtraces now when zellij crashes: One from
`anyhow` (that is implicitly attached to anyhows error reports), and one
from the custom panic handler (which is displayed through `miette`).
* utils/errors: Separate stack traces
in the output of miette. Since we record backtraces with `anyhow` now,
we end up having two backtraces in the output: One from the `anyhow`
error and one from the actual call to `panic`. Adds a comment explaining
the situation and another "section" to the error output of miette: We
print the backtrace from anyhow as "Stack backtrace", and the output
from the panic handler as "Panic backtrace". We keep both for the
(hopefully unlikely) case that the anyhow backtrace isn't existent, so
we still have at least something to work with.
* server/screen: Remove calls to `fatal`
and leave the `panic`ing to the calling function instead.
* server/screen: Remove needless macro
which extended `active_tab!` by passing the client IDs to the closure.
However, this isn't necessary because closures capture their environment
already, and the client_id needn't be mutable.
* server/screen: Handle unused result
* server/screen: Reintroduce arcane macro
that defaults to some default client_id if it isn't valid (e.g. when the
ScreenInstruction is sent via CLI).
* server/tab/unit: Unwrap new results
