This is a small, windows-only dynamic library that can be used to translate Windows MAPI calls to command line arguments.

It handles calls to the functions defined in the mapi.h header, which is not available directly from Microsoft anymore. You can get it from https://github.com/stephenegriffin/MAPIStubLibrary/blob/master/include/MAPI.h

The main purpose is to enable Tutanota Desktop on Windows to handle requests to send files via mail, like they can be issued via the File Explorer context menu or in programs like MS Office and LibreOffice.

The project is set up to compile for the x86_64-pc-windows-gnu target by default, so if you're developing on windows, you'll have to override .cargo/config.toml as shown in the "Commands" section below.

• Microsoft Visual C++ 2019 build tools
• cargo

cargo build --target "x86_64-pc-windows-msvc"

or

cargo build --release --target "x86_64-pc-windows-msvc"

the dll will be placed in ./target/x86_64-pc-windows-msvc/{release,debug}/mapirs.dll

The project is set up so "cargo build" will use the x86_64-pc-windows-gnu target. Running tests requires wine to be installed.

• package gcc-mingw-w64
• cargo
• wine

cargo build

or

cargo build --release

the dll will be placed in ./target/x86_64-pc-windows-gnu/{release,debug}/mapirs.dll

• To get the IntelliJ IDEA Rust Plugin to ignore/check code that is inactive due to attributes like #[cfg(target_os = "windows")], open Ctrl + Shift + A -> Registry... and toggle org.rust.lang.cfg.attributes
• licenses.html has been generated with https://github.com/EmbarkStudios/cargo-about : cargo-about init and then cargo-about generate about.hbs > licenses.html
• the CI script uses clippy and rustfmt to check the code, so run cargo clippy and cargo fmt before committing (in that order)
