check-sieve
This project aims to make checking mail sieve syntax easy and painless. Because breaking your sieve in production sucks.
For a web-based demonstration of check-sieve which is entirely browser-based, visit https://checksieve.com.
Build Dependencies
check-sieve minimally depends on having a modern C++ compiler. On BSD-like systems such as FreeBSD, you'll
also need gmake installed.
Development Dependencies
The following dependencies are required in order to develop check-sieve:
- bison >= v3.0.4
- flex >= v2.5.35
- Python >= 3.7
- Python development headers (for testing)
Additionally, if you want to generate a javascript library, you'll need emscripten installed.
Compiling
At the moment, there are four targets for this project:
check-sieve-- This is a command-line program you can use to verify sieves.libchecksieve.a-- A statically linked library for embedding in other programs (likecheck-sieve).checksieve.so-- This is a python extension created for use by the unit tests in the test directorywasm-- This builds a webassembly javascript library using emscripten.
To build check-sieve simply run make. This will also build the static library.
Running make test will compile checksieve.so and run the python tests in the tests directory.
Finally, running make all will run all of the other targets.
Installing
To install to /usr/local/, simply run the following:
make install
To install to a custom location, build and install with INSTALL_PREFIX set in your environment
to the desired location.
