The core library for Delta Chat, written in Rust

To download and install the official compiler for the Rust programming language, and the Cargo package manager, run the command in your user environment:

$ curl https://sh.rustup.rs -sSf | sh

On Windows, you may need to also install Perl to be able to compile deltachat-core.

Compile and run Delta Chat Core command line utility, using cargo:

$ RUST_LOG=deltachat_repl=info cargo run -p deltachat-repl -- ~/deltachat-db

where ~/deltachat-db is the database file. Delta Chat will create it if it does not exist.

Optionally, install deltachat-repl binary with

$ cargo install --path deltachat-repl/

and run as

$ deltachat-repl ~/deltachat-db

Configure your account (if not already configured):

> send hi

If [email protected] uses DeltaChat, but does not receive message just sent, it is advisable to check Spam folder. It is known that at least gmx.com treat such test messages as spam, unless told otherwise with web interface.

List messages when inside a chat:

> chat

For more commands type:

$ git clone https://github.com/deltachat/deltachat-core-rust.git
$ cd deltachat-core-rust
$ cmake -B build . -DCMAKE_INSTALL_PREFIX=/usr
$ cmake --build build
$ sudo cmake --install build

# run tests
$ cargo test --all
# build c-ffi
$ cargo build -p deltachat_ffi --release

• DCC_MIME_DEBUG: if set outgoing and incoming message will be printed

• RUST_LOG=deltachat_repl=info,async_imap=trace,async_smtp=trace: enable IMAP and SMTP tracing in addition to info messages.

Some tests are expensive and marked with #[ignore], to run these use the --ignored argument to the test binary (not to cargo itself):

$ cargo test -- --ignored

Install cargo-bolero with

$ cargo install cargo-bolero

Run fuzzing tests with

$ cd fuzz
$ cargo bolero test fuzz_mailparse --release=false -s NONE

Corpus is created at fuzz/fuzz_targets/corpus, you can add initial inputs there. For fuzz_mailparse target corpus can be populated with ../test-data/message/*.eml.

To run with AFL instead of libFuzzer:

$ cargo bolero test fuzz_format_flowed --release=false -e afl -s NONE

• vendored: When using Openssl for TLS, this bundles a vendored version.
• nightly: Enable nightly only performance and security related features.

To add the updates from the provider-db to the core, run:

./src/provider/update.py ../provider-db/_providers/ > src/provider/data.rs
