## Install
- Try an [online interactive web demo](https://meli.delivery/wasm2.html "online interactive web demo") powered by WebAssembly
- [`cargo install meli`](https://crates.io/crates/meli "crates.io meli package")
- [Download and install pre-built debian package, static linux binary](https://github.com/meli/meli/releases/ "github releases for meli"), or
- Install with [Nix](https://search.nixos.org/packages?show=meli&query=meli&from=0&size=30&sort=relevance&channel=unstable#disabled "nixos package search results for 'meli'")

## Documentation

See a comprehensive tour of `meli` in the manual page [`meli(7)`](./docs/meli.7).

See also the [Quickstart tutorial](https://meli.delivery/documentation.html#quick-start) online.

After installing `meli`, see `meli(1)`, `meli.conf(5)`, `meli(7)` and `meli-themes(5)` for documentation. Sample configuration and theme files can be found in the `docs/samples/` subdirectory. Manual pages are also [hosted online](https://meli.delivery/documentation.html "meli documentation").

`meli` by default looks for a configuration file in this location: `$XDG_CONFIG_HOME/meli/config.toml`

You can run meli with arbitrary configuration files by setting the `$MELI_CONFIG`
environment variable to their locations, i.e.:

```sh
MELI_CONFIG=./test_config cargo run
```

## Build
For a quick start, build and install locally:

```sh
 PREFIX=~/.local make install
```

Available subcommands for `make` are listed with `make help`. The Makefile *should* be POSIX portable and not require a specific `make` version.

`meli` requires rust 1.39 and rust's package manager, Cargo. Information on how
to get it on your system can be found here: <https://doc.rust-lang.org/cargo/getting-started/installation.html>

With Cargo available, the project can be built with `make` and the resulting binary will then be found under `target/release/meli`. Run `make install` to install the binary and man pages. This requires root, so I suggest you override the default paths and install it in your `$HOME`: `make PREFIX=$HOME/.local install`.

You can build and run `meli` with one command: `cargo run --release`.

### Build features

Some functionality is held behind "feature gates", or compile-time flags. The following list explains each feature's purpose:

- `gpgme` enables GPG support via `libgpgme` (on by default)
- `dbus-notifications` enables showing notifications using `dbus` (on by default)
- `notmuch` provides support for using a notmuch database as a mail backend (on by default)
- `jmap` provides support for connecting to a jmap server and use it as a mail backend (off by default)
- `sqlite3` provides support for builting fast search indexes in local sqlite3 databases (on by default)
- `cli-docs` includes the manpage documentation compiled by either `mandoc` or `man` binary to plain text in `meli`'s command line. Embedded documentation can be viewed with the subcommand `meli man [PAGE]`
- `svgscreenshot` provides support for taking screenshots of the current view of `meli` and saving it as SVG files. Its only purpose is taking screenshots for the official `meli` webpage. (off by default)
- `debug-tracing` enables various trace debug logs from various places around the `meli` code base. The trace log is printed in `stderr`. (off by default)

### Build Debian package (*deb*)

Building with Debian's packaged cargo might require the installation of these
two packages: `librust-openssl-sys-dev librust-libdbus-sys-dev`

A `*.deb` package can be built with `make deb-dist`

### Using notmuch

To use the optional notmuch backend feature, you must have `libnotmuch5` installed in your system. In Debian-like systems, install the `libnotmuch5` packages. `meli` detects the library's presence on runtime.

### Using GPG

To use the optional gpg feature, you must have `libgpgme` installed in your system. In Debian-like systems, install the `libgpgme11` package. `meli` detects the library's presence on runtime.

### Building with JMAP

To build with JMAP support, prepend the environment variable `MELI_FEATURES='jmap'` to your make invocation:

```sh
MELI_FEATURES="jmap" make
```

or if building directly with cargo, use the flag `--features="jmap"'.

# Development

Development builds can be built and/or run with

```
cargo build
cargo run
```

There is a debug/tracing log feature that can be enabled by using the flag
`--feature debug-tracing` after uncommenting the features in `Cargo.toml`. The logs
are printed in stderr, thus you can run `meli` with a redirection (i.e `2> log`)

Code style follows the default rustfmt profile.

## Testing

How to run specific tests:

```sh
cargo test -p {melib, meli} (-- --nocapture) (--test test_name)
```

## Profiling

```sh
perf record -g target/debug/bin
perf script | stackcollapse-perf | rust-unmangle | flamegraph > perf.svg
```

## Running fuzz targets

Note: `cargo-fuzz` requires the nightly toolchain.

```sh
cargo +nightly fuzz run envelope_parse -- -dict=fuzz/envelope_tokens.dict
```
