Contributions are welcome! *However, please open an issue first and discuss the details with me, preferably before you start working on a pull request!* And if possible, avoid very large PRs.
|
||||
I usually can't find the time to process large PRs.
|
||||
|
||||
== Basics
|
||||
|
||||
ReaLearn is written in the programming language https://www.rust-lang.org/[Rust].
|
||||
It makes heavy use of
|
||||
https://github.com/helgoboss/reaper-rs[reaper-rs], which provides Rust bindings for the
|
||||
https://www.reaper.fm/sdk/plugin/plugin.php[REAPER C++ API]. _reaper-rs_ was developed together with ReaLearn but is designed as independent library that can be used for REAPER plug-ins of all sorts.
|
||||
|
||||
Another noteworthy dependency and byproduct of ReaLearn is https://github.com/helgoboss/helgoboss-learn[helgoboss-learn], a crate which provides DAW-agnostic MIDI learn logic (basically the _source_ and _mode_ parts of ReaLearn).
|
||||
Like _reaper-rs_, it's designed as independent library and could be used to provide similar MIDI-learn functionality in other DAWs.
|
||||
|
||||
== Code statistics
|
||||
|
||||
Use https://github.com/XAMPPRocky/tokei[Tokei] or https://github.com/o2sh/onefetch:[Onefetch] to display some interesting statistics about the code, e.g. the lines of code and used languages.
|
||||
The file `.tokeignore` contains code to be ignored when counting the lines of code.
|
||||
|
||||
== Architecture
|
||||
|
||||
See link:ARCHITECTURE.adoc[here].
|
||||
|
||||
== Directory structure
|
||||
|
||||
|===
|
||||
|Directory entry |Content
|
||||
|
||||
|`/` |Workspace root
|
||||
|`/allocator` |A custom global allocator for deferring deallocation in real-time threads
|
||||
|`/api` |Data structures of ReaLearn's preset API (which is e.g. used in the Lua-based ReaLearn Script)
|
||||
|`/base` |Very generic utility code used by many crates in the workspace
|
||||
|`/csi` |Code for interfacing with the ControlSurfaceIntegrator (CSI) project
|
||||
|`/dialogs` |The single source of truth for ReaLearn's GUI dialogs
|
||||
|`/doc` |Documentation
|
||||
|`/extension` |Helgobox REAPER extension (provides some additional convenience around the actual ReaLearn plug-in)
|
||||
|`/helgoboss-license-processor` |Contains code for license processing (currently a private submodule)
|
||||
|`/macros` |Various Rust macros for usage in this project only
|
||||
|`/main` |Main crate: The actual ReaLearn instrument plug-in (`realearn`)
|
||||
|`/playtime-api` |Playtime data structures for describing e.g. clip engine presets
|
||||
|`/playtime-clip-engine` |Playtime Clip Engine for playing/recording clips (currently a private submodule). Is a workspace member because that makes it much simpler to use the same dependency versions everywhere.
|
||||
|`/playtime-clip-engine-placeholder` |A placeholder crate for the Playtime Clip Engine. Users who don't have access to
|
||||
the Playtime Clip Engine submodule, must rename this directory to `playtime-clip-engine` in order to be able to build
|
||||
ReaLearn without feature `playtime`.
|
||||
|`/pot` |Core logic behind Pot Browser, also powers the Pot targets
|

|
||||
|
||||
== Build
|
||||
|
||||
=== All operating systems
|
||||
|
||||
==== Update Cockos WDL (optional)
|
||||
|
||||
[source,shell]
|
||||
----
|
||||
cd main/lib/WDL
|
||||
git checkout main
|
||||
git pull
|
||||
# After updating Cockos WDL, regenerate Rust bindings (because we use WDL's EEL code, for example)
|
||||
cargo build --features generate
|
||||
cargo fmt
|
||||
----
|
||||
|
||||
==== Regenerate Luau language bindings (optional)
|
||||
|
||||
Luau language bindings should be regenerated from Rust after changing something in link:api[api] or link:playtime-api[playtime-api].
|
||||
This is done simply by executing all tests like this:
|
||||
|
||||
[source,shell]
|
||||
----
|
||||
RUST_MIN_STACK=5242880 cargo test --package helgobox-api --lib bindings::luau::export_luau
|
||||
----
|
||||
|
||||
==== Regenerate artwork (optional)
|
||||
|
||||
Artwork such as toolbar icons can be regenerated by running a crate:
|
||||
|
||||
[source,shell]
|
||||
----
|
||||
cargo run helgobox-artwork-processor
|
||||
----
|
||||
|
||||
3 different approaches for generating code ... yes, maybe it's time to unify this ;)
|
||||
|
||||
==== Regenerate diagrams in documentation
|
||||
|
||||
This is about the diagrams in the Antora documentation, e.g. the glue signal flow.
|
||||
|
||||
[source,shell]
|
||||
----
|
||||
sh regenerate-doc-diagrams.sh
|
||||
----
|
||||
|
||||
==== Building with Playtime (can only be done by Helgoboss)
|
||||
|
||||
Add this to `$HOME/.cargo/config` (otherwise Cargo will have issues fetching the private submodules):
|
||||
|
||||
[source,ini]
|
||||

=== Windows
|
||||
|
||||
In the following, you will find the complete instructions for Windows 10/11, including Rust setup.
|
||||
Points where you have to consider the target architecture (for example, REAPER 32-bit vs. 64-bit) are marked with :star:.
|
||||
|
||||
. Enable "Developer mode" in the Windows settings (this is needed because ReaLearn uses link:https://stackoverflow.com/a/59761201[Symlinks within its Git repository])
|
||||
. Setup "Visual Studio" (currently tested with version 2022)
|
||||
* Rust uses native build toolchains.
|
||||
On Windows, it's necessary to use the MSVC (Microsoft Visual Studio C++) toolchain because REAPER plug-ins only work with that.
|
||||
* https://visualstudio.microsoft.com/downloads/[Visual Studio downloads] → All downloads → Tools for Visual Studio 2022
|
||||
→ Build Tools for Visual Studio 2022
|
||||
* Start it and follow the installer instructions
|
||||
* Required components
|
||||
** Workloads tab
|
||||
*** "C++ build tools" (large box on the left)
|
||||
*** Make sure "Windows 10 SDK" is checked on the right side (usually it is)
|
||||
*** If on Windows ARM64: Make sure "C++ Clang-Tools" is checked on the right side (normally not checked!, currently necessary for compilation of `ring` dependency)
|
||||
** Language packs
|
||||
*** English
|
||||
. Setup Rust
|
||||
* https://www.rust-lang.org/tools/install[Download] and execute `rustup-init.exe`
|
||||
* Accept the defaults
|
||||
* Set the correct toolchain default :star:
|
||||
+
|
||||
[source,shell]
|
||||
----
|
||||
rustup default 1.84.0-x86_64-pc-windows-msvc
|
||||
----
|
||||
. If you want to regenerate bindings (usually not necessary): Download and install LLVM from https://github.com/llvm/llvm-project/releases (look for something like `LLVM-*-win64.exe`)
|
||||
. Download and install https://git-scm.com/download/win[Git for Windows]
|
||||
. Clone the ReaLearn Git repository
|
||||
+
|
||||
[source,shell]
|
||||
----
|
||||
git clone https://github.com/helgoboss/helgobox.git`
|
||||
cd helgobox
|
||||
git checkout v2.16.0 # or any other release tag
|
||||
|
||||
# ONLY IF YOU ARE HELGOBOSS
|
||||
git submodule update --init
|
||||
|
||||
# OTHERWISE
|
||||
git submodule update --init main/lib/WDL main/lib/helgoboss-learn
|
||||
rmdir playtime-clip-engine
|
||||
rename playtime-clip-engine-placeholder playtime-clip-engine
|
||||
----
|
||||
. Build ReaLearn (after that you should have a `helgobox.dll` in `target\debug`)
|
||||

|
||||
[source,shell]

|
||||
cargo build --features egui

|
||||
|
||||
==== Windows 7 support is gone and its future is uncertain
|
||||
|
||||
Helgobox 2.16.15 brought back Windows 7 support, which has gone missing at some point before that.
|
||||
This was primarily achieved by producing the Windows build using the last official Rust version that supported Windows 7, namely Rust 1.77.2.
|
||||
|
||||
However, it turned out that it's very hard to stick with that version.
|
||||
It means having to give up on new Rust features.
|
||||
But most importantly, it means updating dependencies is not possible if they raise their MSRV (minimal supported Rust version).
|
||||
A high price to pay for a rarely used OS.
|
||||
|
||||
An alternative would be to use the tier 3 target `x86_64-win7-windows-msvc`.
|
||||
Compilation works using the `RUSTC_BOOTSTRAP` hack:
|
||||
|
||||
.PowerShell
|
||||
[source]
|
||||
----
|
||||
$env:RUSTC_BOOTSTRAP=1
|
||||
# For compiling indexmap
|
||||
$env:CARGO_FEATURE_STD=1
|
||||
cargo build -Z build-std --release --target x86_64-win7-windows-msvc
|
||||
----
|
||||
|
||||
However, linking fails because `windows.lib` can't be opened.
|
||||
Probably related to https://www.reddit.com/r/rust/comments/1dikeq6/compiling_for_win7_missing_windows0485lib/[this] and https://github.com/rust-lang/rust/issues/128218#issuecomment-2251864932[this] issue.
|
||||
If -- and only if -- users are genuinely interested in a working Windows 7 build of ReaLearn, I would look into it a bit further.

----
|
||||
|
||||
Some words about the native dependencies:
|
||||
|
||||
* `curl git build-essential pkg-config` are bare essentials.
|
||||
* `php` is needed to translate the ReaLearn dialog resource file to C++ so it can be processed by the SWELL
|
||||
dialog generator. It's also necessary for generating the 64-bit EEL assembler code. All of this is the
|
||||
typical WDL C++ way of doing things, no Rust specifics here.
|
||||
* `nasm` is needed for assembling the 64-bit EEL assembler code to produce `asm-nseel-x64.o`, which is necessary to make the custom https://www.cockos.com/EEL2/[EEL] control and feedback transformations in ReaLearn's absolute mode work.
|
||||
* `llvm-dev libclang-dev clang` are necessary for building with feature `generate` (to generate bindings to C).
|
||||
* `libxdo-dev` is needed to control the mouse (see target "Global: Mouse")
|
||||
* `libudev-dev` is needed for connecting to Stream Deck via HID API
|
||||
* `libx11-dev libxcursor-dev libxcb-dri2-0-dev libxcb-icccm4-dev libx11-xcb-dev mesa-common-dev libgl1-mesa-dev libglu1-mesa-dev` are necessary for https://github.com/BillyDM/egui-baseview[egui-baseview] (https://github.com/emilk/egui[egui] is the GUI framework used for ReaLearn's control transformation editor)
|
||||
* `libspeechd-dev` is necessary for the speech source
|
||||
* `libgtk-3-dev` is necessary to obtain the X window and X display from a SWELL OS window, in order to fire up OpenGL/egui in it
|
||||
|
||||
=== macOS
|
||||
|
||||
The following instructions include Rust setup.
|
||||
However, it's very well possible that some native toolchain setup instructions are missing, because I don't have a bare macOS installation at my disposal.
|
||||
The Rust installation script should provide you with the necessary instructions if something is missing.
|
||||

# Build ReaLearn

cargo build --features egui
|
||||
----
|
||||
|
||||
== GUI
|
||||
|
||||
The GUI dialogs are defined in the `dialogs` directory.
|
||||
Whenever ReaLearn is built, the code there generates an old-school Windows dialog resource file (`target/generated/msvc.rc`) and a Rust file which contains all the resource ID constants (`main/src/infrastructure/ui/bindings.rs`).
|
||||
|
||||
Previously I used the Visual Studio C++ 2019 resource editor to WYSIWYG-edit this file as part of the solution
|
||||
link:main/src/infrastructure/ui/msvc/msvc.sln[msvc.sln], but this was too tedious.
|
||||
|
||||
WARNING: You can still preview the generated file in Visual Studio but don't edit the RC file, the changes will be overwritten at build time!
|
||||
Adjust the Rust code in the `dialogs` directory instead.
|
||||
|
||||
On macOS and Linux, an extra step will happen at build time: It will try to use a PHP script (part of Cockos SWELL) to generate
|
||||
`target/generated/msvc.rc_mac_dlg`, which is a translation of the RC file to C code using SWELL.
|
||||
So make sure you have PHP installed on these platforms!
|
||||
|
||||
== Test
|
||||
|
||||
Yes, there are tests but there should be more.
|
||||
While ReaLearn's basic building blocks
|
||||
https://github.com/helgoboss/helgoboss-learn[helgoboss-learn] and https://github.com/helgoboss/reaper-rs[reaper-rs]
|
||||
are tested pretty thoroughly, ReaLearn itself has room for improvement in that aspect.
|
||||
|
||||
=== Unit tests
|
||||
|
||||
Unit tests should be executed with a higher stack size because there's one unit test that generates and formats Lua code and this currently overflows the stack in debug builds.
|
||||
|
||||
[source,shell]
|
||||
----
|
||||
RUST_MIN_STACK=104857600 cargo test
|
||||
----
|
||||
|
||||
=== Integration tests
|
||||
|
||||
There's a growing built-in integration test, launchable via action `[developer] ReaLearn: Run integration test`.
|
||||
In future, it would be nice to run this integration test during continuous integration, just like in _reaper-rs_.
|
||||
|
||||
== Log
|
||||
|
||||
It's possible to make ReaLearn output log messages to `stdout` by setting the `HELGOBOX_LOG` environment variable, e.g. to `debug,vst=info`.
|
||||
It follows https://docs.rs/env_logger/0.8.2/env_logger/index.html[this] format.
|
||||
Beware that e.g. on Windows, `stdout` is not shown, not even when executing REAPER from the command line.
|
||||
One way to make it visible is to execute REAPER with a debugger.
|
||||
|
||||
== Metrics
|
||||
|
||||
It's possible to make ReaLearn expose execution metrics.
|
||||
|
||||
=== Prometheus endpoint
|
||||
|
||||
* If the projection server is running, metrics will then be exposed at `/realearn/metrics` in the popular
|
||||
https://prometheus.io/[Prometheus] format.
|
||||
That's great for visualization.
|
||||
** Just add this to your `prometheus.yml` (you might need to adjust the port):
|
||||
[source,yaml]
|
||||
----
|
||||
scrape_configs:
|
||||
- job_name: 'realearn'
|
||||
metrics_path: '/realearn/metrics'
|
||||
static_configs:
|
||||
- targets: ['localhost:39080']
|
||||
----
|
||||
|
||||
** If you don't have any metrics enabled, this will show zeros only.
|
||||
|
||||
Prometheus is usually available at http://localhost:9090/.
|
||||
|
||||
=== ReaLearn metrics
|
||||
|
||||
- You can turn on ReaLearn metrics by setting the environment variable `HELGOBOX_METRICS` (value doesn't matter).
|
||||
- If this environment variable is set (value doesn't matter), ReaLearn will record some metrics and expose them on the Prometheus endpoint mentioned above.
|
||||
- If ReaLearn is built with the Playtime Clip Engine, this flag will also enable Clip Engine metrics.
|
||||
This can negatively effect clip playing performance because many clip engine metrics are captured in real-time threads.
|
||||
|
||||
== Debug
|
||||
|
||||
=== Debug REAPER scanning ReaLearn
|
||||
|
||||
Set `vst_scan=1` in the `[reaper]` section of `reaper.ini`.
|
||||
That makes the debugged REAPER process itself do the scanning.
|
||||
|
||||
=== Obtain debug symbols
|
||||
|
||||
Debug symbols are stripped from release builds but stored as build artifact of the GitHub Actions "Create release" workflow.
|
||||
If you want the symbols for a specific build, proceed as follows:
|
||||
|
||||
. Open the https://github.com/helgoboss/helgobox/actions?query=workflow%3A%22Create+release%22[list of ReaLearn "Create release" workflows].
|
||||
. Use the branch filter to show all releases builds made for a specific version, e.g. "v1.11.0".
|
||||
. Click the desired workflow.
|
||||
** GitHub seems to do a fuzzy search, so if there are pre-releases (e.g. "v1.11.0-pre2"), you will see them, too.
|
||||
** In that case, just choose the latest one.
|
||||
. You will see a list of artifacts, one for each OS-architecture combination.
|
||||
. Download the one you need and unzip it.
|
||||
** You will find both the library file and the symbol file (e.g. `realearn.pdb` for a Windows build).
|
||||
|
||||
=== Turn on complete backtraces
|
||||
|
||||
As soon as you have the debug symbols, you can make ReaLearn print full backtraces (including line number etc.) in the REAPER ReaScript console.
|
||||
Here's how you do it.
|
||||
|
||||
==== Windows
|
||||
|
||||
. Set the environment variable `_NT_ALT_SYMBOL_PATH` to some directory of your choice.
|
||||
. Copy the PDB file in there.
|
||||
. Fire up REAPER with ReaLearn an make it panic.
|
||||
You should see a complete backtrace now.
|
||||
|
||||
=== Lookup symbols for symbol-less backtraces
|
||||
|
||||
The problem with release builds is that they don't contain debug symbols and therefore backtraces usually contain not much more than memory addresses.
|
||||
Especially backtraces generated by Windows release builds leave a lot to be desired.
|
||||
|
||||
ReaLearn has a built-in REAPER action which attempts to look up symbol information for a given error report:
|
||||
"ReaLearn: Resolve symbols from clipboard".
|
||||
Works on Windows only.
|
||||
To be used like this:
|
||||
|
||||
. Make sure the PDB for the release build in question is on the search path (see section above).
|
||||
. Fire up an ReaLearn using exactly that release build.
|
||||
. Copy the error report to the clipboard.
|
||||
. Execute the action.
|
||||
|
||||
=== Differences between debug levels
|
||||
|
||||
==== macOS
|
||||
|
||||
Insights:
|
||||
|
||||
* The size difference between `debug = 1` and `debug = 2` is almost nothing (both 58 MB), and there's nothing to gain from `debug = 2` in terms of stack traces.
|
||||
* The size difference between `debug = 0` and `debug = 1` is around 5 MB (53 MB vs. 58 MB), and `debug = 1` only makes a difference if the source files exist (showing line numbers), and only for panics.
|
||||
* Hard crash stack traces are completely independent of the `debug` value.
|
||||
They are always helpful except when stripping the symbols.
|
||||
* `strip = symbols` leads to the smallest binaries (38 MB) but also to completely useless stack traces, both in soft and hard crashes.
|
||||
However, `split-debuginfo = "packed" seems to fix this at least for hard crashes, at a similar-sized binary (not for panics though) ... even if the DSYM directories are not on disk. What also fixes this for hard crashes is stripping via `strip -u -r`.
|
||||
We shouldn't do that anymore!
|
||||
* `strip = debuginfo` leads to an okay size reduction (53 MB) but removes line numbers even if source files exist.
|
||||
However, `split-debuginfo = "packed"` solves this by creating dSYM directories, as long as they are there.
|
||||
|
||||
Takeaway:
|
||||
|
||||
* We should build with `debug = 2`
|
||||
** While `debug = 1` is actually enough for most purposes, it can't hurt building with `debug = 2` since we strip debuginfo anyway.
|
||||
So there's no size difference for the final binary.
|
||||
That way we have more debuginfo on the server whenever we need it.
|
||||
* `strip = debuginfo` is the max we can strip away if we want panics to contain something useful
|
||||
* `strip = symbols` is only okay if we are fine with bogus stack traces in panics.
|
||||
In that case, we must use `split-debuginfo = "packed"` to get at least detailed stack traces in case of hard crashes.
|
||||
* We should use `split-debuginfo = "packed"` in all cases.
|
||||
* Would be good to find a way to leverage symbols for panic stack traces, but I think there is none.

== Release
|
||||
|
||||
This serves mainly as a checklist for Helgobox's author.
|
||||
|
||||
. Check licenses via `cargo deny check licenses` and make sure the outcome is "licenses ok"
|
||||
. Update license report (see above)
|
||||
. Take care of app versioning
|
||||
** Plug-in repository: Adjust `HOST_API_VERSION` and `MIN_APP_API_VERSION`
|
||||
** App repository: Adjust `appApiVersion` (macOS, Swift), `APP_API_VERSION` (Windows, C++) and `_minHostApiVersionString` (Dart)
|
||||
. Bump up the app version number in `pubspec.yaml`.
|
||||
. Bump up the plug-in version number in link:main/Cargo.toml[main/Cargo.toml].
|
||||
** Either to a prerelease (e.g. `2.0.0-pre1`) or a final release (e.g. `2.0.0`).
|
||||
** This is important for having the correct version number displayed in ReaLearn UI.
|
||||
. Build at least once via `cargo build --features playtime,egui`.
|
||||
** This updates `Cargo.lock` and is important for not having the `-dirty` display in ReaLearn UI.
|
||||
. Update the user guide if not done already.
|
||||
. Create a version tag via `git tag v2.0.0-pre1`.
|
||||
. Push via `git push origin v2.0.0-pre.1`.
|
||||
. While GitHub Actions executes the release job, take care of the following.
|
||||
** Can only be done by @helgoboss because it needs access to the https://github.com/helgoboss/helgoboss-org[helgoboss.org website repository].
|
||||
** Add a changelog entry in https://github.com/helgoboss/helgoboss-org/blob/master/src/data/projects/realearn/data.yaml[data.yaml].
|
||||
** In `src/snippets/projects/realearn/repo`, enter `git checkout master` and `git pull` to pull the latest user guide changes.
|
||||
** Push via `git push origin HEAD` and wait until Netlify deployed the page.
|
||||
** All the following stuff needs to be done using Netlify's branch preview if it's a prerelease!
|
||||
** Update https://github.com/helgoboss/reaper-packages/blob/master/index.xml[helgoboss ReaPack index].
|
||||
*** Generate ReaLearn-only ReaPack index by requesting https://www.helgoboss.org/projects/realearn/reapack.txt[/projects/realearn/reapack.txt].
|
||||
*** Integrate the generated index by copying everything from `<category name="Extensions">` and pasting it to the
|
||||
https://github.com/helgoboss/reaper-packages/blob/master/index.xml[helgoboss ReaPack index] without overwriting the preset categories on the top of the file.
|
||||
*** Don't push the index yet!
|
||||
** Create a REAPER forum ReaLearn thread entry with help of https://www.helgoboss.org/projects/realearn/reaper-forum.txt[/projects/realearn/reaper-forum.txt]
|
||||
but don't submit yet!
|
||||
** Download the user guide by requesting https://www.helgoboss.org/projects/realearn/user-guide[/projects/realearn/user-guide].
|
||||
** Copy the corresponding changelog entry in markdown format by requesting https://www.helgoboss.org/projects/realearn/changelog.md[/projects/realearn/changelog.md].
|
||||
. Once the release job has finished successfully, edit the not-yet-published release that has been created.
|
||||
** Paste the copied changelog entry to the release notes.
|
||||
** Manually add the previously downloaded user guide as release artifact named `realearn-user-guide.pdf`.
|
||||
. Publish the release.
|
||||
. Push the https://github.com/helgoboss/reaper-packages/blob/master/index.xml[helgoboss ReaPack index].
|
||||
. Submit the REAPER forum ReaLearn thread entry.
|
||||
. Check if synchronization of the ReaPack repository works.
|
||||
. Update website's `config.yaml` latest versions (for update notifications)
|
||||
|
||||
== Troubleshooting
|
||||
|
||||
=== Windows: ReaLearn DLL doesn't unload
|
||||
|
||||
In REAPER for Windows it's possible to enable complete unload of VST plug-ins (Options -> Settings/Preferences -> Plug-ins -> VST -> Allow complete unload of VST plug-ins).
|
||||
This also affects ReaLearn.
|
||||
Removing the last ReaLearn instance should work with and without this flag enabled, it's important to test this.
|
||||
|
||||
I ran into a case in which Windows was *not* unloading ReaLearn even though that option was enabled.
|
||||
The reason turned out to be a registry entry that Windows must have created automatically at some point:
|
||||
|
||||
`HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\Layers` -> `C:\REAPER\reaper.exe` with value `$ IgnoreFreeLibrary<realearn.dll>`
|
||||
|
||||
Removing this entry made unloading work again.
|
||||
What a nasty trap!
