rversions's readme


rversions is a complete rewrite of versions in Rust. It is an open source (GPL v3) software that checks releases and versions of your favourite programs through RSS or Atom feeds and tells you which one has been released since the last time is has been checked.

It can check projects from any website or repository that provides an RSS or an Atom feed to track releases or tags that may contain versions. Projects must be added to a YAML file (by default ~/.config/rversions/rversions.yaml).

Unlike versions, rversions tracks major versions independently: if a 22.4.3 is created after a 23.2.3 and previous versions were 22.4.2 and 23.1.9 it will be taken into account and both will be printed and remembered.

rversions uses and produces text files. Those files are cache files written into ~/.cache/rversions directory. *.cache cache files are containing the project list and their associated versions (the latest in each sub version if any), the date at which the release occurred and the date when rversions checked it.


To install rversions you need first to install Rust.

From crates.io

Use cargo to directly install rversions for your system: cargo install rversions (depending on your system this may take some time - on mine it takes nearly 5 minutes).

From source

Use git to clone the repository and build the release binary of rversions:

git clone https://gitlab.com/delhomme/rversions.git
cd rversions
cargo build --release

This will compile all needed dependencies and at last will produce a binary program in target/release/ named rversions. One may call it directly to use it:

./target/release/rversions --help

YAML configuration file structure

By default rversions will try to load it's configuration file from ~/.config/rversions/rversions.yaml if it exists. Such file is a list of sites definitions and must comply to the following format:

  - name: 'FreshCode'
    url: 'https://freshcode.club/projects.rss'
    type: list
      - name: FileZilla
        filter-in: 'v([\d\.\-rRcC]+)'
      - name: sauvegarde
      - name: git

  - name: 'pypi'
    url: 'https://pypi.org/rss/updates.xml'
    type: list
      - name: PyYAML
      - name: feedparser

  - name: 'github'
    url: "https://github.com/{}/tags.atom"
    type: byproject
      - name: hashicorp/terraform
        filter-in: 'v([\d\.-rRcCbBeEtTaAlLpPhH]+)'
      - name: ANSSI-FR/MLA
        filter-in: 'mlar-v([\d\.]+)'
      - name: StackStorm/st2
        entry: 'last checked'
      - name: gohugoio/hugo
        filter-in: '(\d+.\d+.\d+[\.\-\+\w]+)'
        entry: 'last checked'

Sites must have a name, an url and a type. There is two types of sites:

  • list: The site has one feed with all projects in it such as freshcode.club or fossies.org. Those sites are expected to publish their projects in the same format between posts and a site level filter-in: regular expression can be defined. This regular expression must have two matching groups: one for project's name and one for it's version. Similarly site level entry: can be defined to print either latest entry or all entries found from last checked time. A site level multiproject: field can be defined in case one post contains more than one project update (for instance mxnet: 1.9.1 b0; libmxnet: 1.9.1 b0; mxnet-openblas: 1.9.1 b0. It as to be an array of characters delimiters for each projects such as [',', '|', ';'].
  • byproject: The site gives access to one feed per project such as gitlab for instance. Brackets {} represents the name of the project as found in the projects: list for the site. Those projects can be listed directly with name: field and may take options. You can specify either a filter-in:, filter-out: or an entry: type option (or all at the same time).

Common fields that may be defined:

  • filter-in: is a regular expression used to match version number which will then be used to sort versions among themselves.
  • filter-out: is a regular expression used to exclude some versions (for instance all -rc versions) from being reported.
  • entry: is used to determine if versions has to print the latest entry (default behavior) or all new entries from the last checked date.

A real life example file is provided: examples/versions.yaml


rversions is a command line tool that may be invoked directly in a terminal or in scripts. Note that rversions is compliant with NO_COLOR specification. You can have full usage options invoking rversions command with --help flag. It will give you something similar to:

    -d, --debug                  Starts in debug mode and prints things that may help
    -f, --filename <FILENAME>    Configuration file filename (in YAML format) with projects to check
    -h, --help                   Print help information
    -l, --list                   List all projects and their version in cache
    -V, --version                Print version information

For instance to test the real life example you can do: ./target/release/rversions -f examples/versions.yaml
