* xtask/pipeline: Fix publish task
which was previously stuck in an infinite loop after successfully

error conditions but not breaking out of the inner infinite loop in case
of success.
* xtask: Improve publish failure UX
by offering the user more actions to choose from when an error occured.
* utils/assets: Add generated prost files to assets
to make sure they're available at build time and are picked up by all
components. It seems we hit some strange bug with the build script
where, when running `cargo publish --dry-run` the build script **is
not** run before regularly compiling zellij-utils. This shouldn't happen
according to the docs, but I cannot explain what's causing it. So we're
using this as a workaround for now to make a smooth release.

when dry-running a publish.
* utils: Add comments to protobuf-related code
to explain why these changes were performed. The comments all include a
link to an issue comment explaining the situation in greater detail.
* xtask: Build protobuf definitions

plugins when required. This should ensure that all crates built through

* rust: Update toolchain version to 1.67
* xtask/pipeline/publish: Drop manual "wait"
for crates.io to catch up, which is obsolete with rust 1.66 and up.
Cargo does that on its own now. See
https://github.com/rust-lang/cargo/pull/11062
* xtask: Add function to obtain asset_dir
instead of assembling it on demand throughout the codebase.
* xtask/run: Add '--quick-run' flag
as a convenient shorthand for `cargo xtask run --data-dir
$PROJECT_ROOT/zellij-utils/assets`.
* cargo: Add 'q' command alias
as a shorthand for 'cargo xtask run --quick-run'
* cargo: Update thiserror to 1.0.40
* cargo: Update anyhow to 1.0.70
and specify dependency only once inside `zellij-utils`, not inside the
zellij root crate.
* cargo: Update names to 0.14.0
* cargo: Update miette to 5.7.0
and re-export the dependency from zellij-utils, to avoid duplicate
(incompatible) includes from inside zellij-utils and the root crate.
* cargo: Update dialoguer to 0.10.4
* fix formatting
* changelog: Add PR #2375
* fix(cli): take default shell from config if it exists when opening new tab
* fix(cli): take layout dir from config when opening new tab if it exists
* style(fmt): rustfmt
* zellij: Move "populate_data_dir" to utils
and rewrite it to take a second, optional parameter. This allows
controlling whether only a specific asset should be installed. We do
this as preparation for being able to recover from a plugin version
mismatch error, where we will need to repopulate the data dir for
offending plugins.
* server/wasm_vm: Recover from PluginVersionMismatch
Adds a global plugin cache that stores, per plugin config, the wasmer
module associated with it. Make `start_plugin` take the pre-populated
module and create only the necessary modifications to the wasm env etc.
* utils: Fix formatting
* zellij: Delete non-existent module
* utils/shared: fix missing "set_permissions"
function when not on unix systems.
* server/wasm_vm: Don't populate cachedir
with serialized versions of the WASM plugins.
* utils/input/plugins: load wasm bytes from assets
for builtin plugin specifications. This foregoes any need to:
- Dump the plugin bytes to disk at all and
- subsequently read the plugin bytes from disk
* zellij: Disable default asset installation
which previously installed only the builtin plugins to disk. This is no
longer necessary because now we can load the builtin plugins directly
from the application binary.
* utils/input/plugins: Update docs
* utils/input/plugins: Add 'is_builtin' method
to `PluginConfig` that returns true if the plugin configuration refers
to a builtin plugin.
* wasm_vm: Remove plugin version mismatch handling
because a version mismatch in an internal plugin is now unfixable, with
the plugins being loaded from the running binary, and we have no control
over external plugins in the first place.
* cargo: Reintroduce feature flag
for `disable_automatic_asset_installation`
* utils/consts: Add `ASSET_MAP`
which currently contains the compiled WASM plugins.
* utils/shared: Fix clippy lint
* utils/errors: Add more `ZellijError` variants
* zellij: Make loading internal plugins optional
by reenabling the `disable_automatic_asset_installation` flag and
utilizing it for this purpose. Changes plugin search behavior to throw
better errors in case the builtin plugins cannot be found, depending on
the state of this feature.
* utils/errors: Apply rustfmt
* utils/setup: Allow dumping builtin plugins
to a specified folder on disk. This is meant to be an "escape hatch" for
users that have accidentally deleted the builtin plugins from disk (in
cases where the plugins aren't loaded from inside the zellij binary).
* utils/input/plugins: Update docs
* utils/setup: Add hint to `setup --check` output
when zellij was built without the `disable_automatic_asset_installation`
flag and will thus not read builtin plugins from the "PLUGIN DIR".
* utils/setup: Refine `setup --dump-plugins`
to dump to:
- The default "DATA DIR" when no option is provided with the argument,
or
- The provided option, if existent
Also print a message to stdout with the destination folder that the
plugins are dumped to.
* server/wasm_vm: Ignore "NotFound" errors
when attempting to delete the non-existent plugin data directories. This
silences an error message that otherwise ends up in the logs when
quitting zellij.
* utils/errors: Extend "BuiltinPluginMissing" msg
to hint the user to the `zellij setup --dump-plugins` command to fix
their issues for them!
* utils/errors: Track caller in calls to `non_fatal`
which will hopefully, once closures can be annotated, allow us to
display the location of the call to `non_fatal` in log messages.
* utils/input/plugins: Fix plugin lookup
to prefer internal assets if available. It was previously broken because
sorting the paths vector before deduping it would bring the paths into a
wrong order, looking up in the plugin folder first.
Also print a log message when a plugin is being loaded from the internal
assets but exists on disk, too.
* Apply rustfmt
* make: build-e2e depends on wasm-opt-plugins
so it updates the assets when building the binary
* server/qwasm_vm: Remove var
* utils/consts: Add plugins from target folder
and include them in the asset map from there, too. Include plugins from
debug or release builds, depending on the build type.
* utils/consts: Take release plugins from assets
instead of the target/release folder. The latter will break
installations from crates.io, because we currently rely on including the
plugins we pre-compiled and distribute along with the binary.
* server/wasm_vm: Reintroduce .cache folder
to speedup subsequent application launches.
* cargo: Reorder workspace members
to improve behavior with `cargo make` with respect to compilation order.
* Makefile: restructure plugin tasks
* Makefile: Fix CI errors
* Makefile: More CI diagnosis
* github: Install wasm-opt in e2e test workflow
* Makefile: Build plugins for e2e-test target
* server/Wasm_vm: Reorder plugin folder creation
so no folders are created in the plugin cache when loading a plugin
fails due to not being present or similar.
* update plugins testcommit
* makefile: Change job order
* changelog: Add PR #1924
* 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.
* 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.
Fixes: #1735
* changelog: fix recursive zellij sessions
* feat: add capability to dispatch actions from cli
Add capability to dispatch actions from the cli.
Can be invoked through `zellij action [actions]`
Automatically sends the action either to the current session,
or if there is only one session to the single session.
If there are multiple sessions, and no session is specified it will
error out.
Example:
1.
```
zellij action "[NewTab: , NewTab: ]"
```
2.
```
zellij -s fluffy-cat action '[NewPane: , WriteChars: "echo Purrr\n" ]'
```
3.
```
zellij -s fluffy-cat action '[ CloseTab, ]
```
* add: error message on malformed input
Add an error message on malformed input, for the `action`'s dispatch.
Rather than resulting in a panic.
* add: function to query the client id
* add: send specific actions to certain clients
Adds ability to send actions, that don't impact the server state
to all connected clients. For example `MoveFocus`
* add: client_id to non blocking actions
* chore(fmt): `cargo fmt`
* add: pick correct session, if there is exactly one
* add: use correct `client_id` for detach action
* add: make `[ ]` opaque to the user
* add: miette to toplevel to improve error message
* add: fake client reading configuration
Add the fake client reading configuration files,
this allows actions, that rely on configuration work
correctly. This is an intermediate solution, and should ideally not
be needed. It would be better if most of this state would be handled
by the server itself.
* chore(fmt): rustmt
* add: ability to detach multiple clients
Add ability to detach multiple clients at the same time.
* remove: obsolete functionality
* remove: unused functionality
* add: send correct action upon exiting
* chore(update): cargo update
* feat: Attach sessions by unique name prefix (#1169)
This makes attaching to sessions more convenient since only the first character(s) of the
session name must be typed.
If this prefix matches multiple sessions and is therefore ambiguous, zellij will complain
and show all sessions names starting with these characters.
If any session name matches the given string exact, it is attached immediately, therefore
it is always possible to attach to every session, even if the set of session names is not
prefix-free.
* Add feature to changelog
* Try to fix flaky e2e test
* fix(feat): `disable_automatic_asset_installation`
This fixes a regression in the feature system:
The asset installation didn't get turned off by the feature.
Add error logging to the install functions.
Properly show features in setup
disable `mkdir` in `wasm_vm` on `feature-disable-asset-installation`
Alternative:
Is this even needed? We make sure the directory is there upon the
normal asset installation.
fixes#1130
add the ability to toggle boolean options with a cli flag:
example:
if the pane frames are turned off in the config file,
then passing in the `--no-pane-frames` flag will toggle the
pane frames on
