# meli
For a quick start, build and install locally:
PREFIX=~/.local make install
Available subcommands:
- meli (builds meli with optimizations in `$CARGO_TARGET_DIR`)
- install (installs binary in `$BINDIR` and documentation to `$MANDIR`)
- uninstall
Secondary subcommands:
- clean (cleans build artifacts)
- check-deps (checks dependencies)
- install-bin (installs binary to `$BINDIR`)
- install-doc (installs manpages to `$MANDIR`)
- help (prints this information)
- dist (creates release tarball named `meli-VERSION.tar.gz` in this directory)
- deb-dist (builds debian package in the parent directory)
- distclean (cleans distribution build artifacts)
The Makefile *should* be portable and not require a specific `make` version.
# Documentation
After installing meli, see `meli(1)` and `meli.conf(5)` for documentation. Sample configuration and theme files can be found in the `samples/` subdirectory.

# Building
meli requires rust 1.39 and rust's package manager, Cargo. Information on how
to get it on your system can be found here: <>
With Cargo available, the project can be built with
2020-02-04 18:05:49 +00:00
The resulting binary will then be found under `target/release/meli`
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
See `meli(1)` and `meli.conf(5)` for documentation.
You can build and run meli with one command:
cargo run --release
While the project is in early development, meli will only be developed for the
linux kernel and respected linux distributions. Support for more UNIX-like OSes
is on the roadmap.
## Features
Some functionality is held behind "feature gates", or compile-time flags. The following list explains each feature's purpose:
- `notmuch` provides support for using a notmuch database as a mail backend
- `jmap` provides support for connecting to a jmap server and use it as a mail backend
- `sqlite3` provides support for builting fast search indexes in local sqlite3 databases
- `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.
- `debug-tracing` enables various trace debug logs from various places around the meli code base. The trace log is printed in `stderr`.
## Building in Debian
2020-02-04 18:05:49 +00:00
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
2020-02-04 18:05:49 +00:00
2020-02-27 14:36:47 +00:00
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.

# Building with JMAP
To build with JMAP support, prepend the environment variable `MELI_FEATURES='jmap'` to your make invocation:
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.
# Configuration
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, ie:
MELI_CONFIG=./test_config cargo run
# Testing
How to run specific tests:
cargo test -p {melib, meli} (-- --nocapture) (--test test_name)
# Profiling
perf record -g target/debug/bin
