README
swapview is a simple program to view processes' swap usage on Linux. This repository is the one of multiple implementations, intended to be a lilydjwg's version of Hello World program. For a daily use version, see [swapview](https://github.com/lilydjwg/swapview).
How to run the speed comparison
----
Install all the dependencies for your interested versions, then run `make -k`. It will build all that can be built.
To test and see the speed comparison, either use `bench.py` or `run_benchmark`. `bench.py` uses Python 3.4+ and depends on `python-toml`.
`run_benchmark` is a Rust version. Install latest Rust and Cargo, then change your working directory to `benchmark` and run `cargo build --release`. If the build fails, it's because your Rust is too old or too new....
Run `./run_benchmark =1.8
* Guile >= 2.1
* Haskell, requires `haskell-strict`
* Java, >= Java 8
* Lua, requires lua-filesystem, works with 5.1, 5.2, 5.3 and LuaJIT
* newlisp (tested with 10.7.5)
* Nim (tested with 0.17.0)
* NodeJS, requires sprintf (will be installed by `make`)
* NodeJS_async, another NodeJS version which use async I/O, requires sprintf and async (will be installed by `make`)
* NodeJS_cluster, uses multiple forked worker process via Node Cluster API
* OCaml
* FreePascal
* Perl
* Python, works with Python 2 & 3
* Python3_bytes
* R
* Racket
* Ruby and Rubinius
* Rust, >= 1.20
* Scala
* Vala, requires `glib2` (`libglib-2.0` and `libgio-2.0`)
* Tcl, >= 8.6
* Zig, tested with 0.9.1
Contributions
----
Contributions are welcome! Improve current ones, or submit new one. But make
sure your implementations meet the following requirements:
1. Must be readable and maintainable
2. Output exact the same format as other versions (but sorting may be
unstable)
3. Try to be efficient
4. Please include a `Makefile` if appropriate
5. Don't forget to tell the compiler to optimize
My Result
----
This is tested on Arch Linux, with latest versions of compilers and interpreters available there at testing time. CPU is Intel(R) Core(TM) i7-7700HQ.
