All commands used in your version source files
Running
To see available options:
./nvchecker --help
Run with one or more software version source files:
./nvchecker source_file
You normally will like to specify some “version record files”; see below.
Version Record Files
Version record files record which version of the software you know or is available. They are simple key-value pairs of (name, version) seperated by a space[v0.3]:
fcitx 4.2.7 google-chrome 27.0.1453.93-200836 vim 7.3.1024
Say you’ve got a version record file called old_ver.txt which records all your watched software and their versions, as well as some configuration entries. To update it using nvchecker:
./nvchecker source.ini
See what are updated with nvcmp:
./nvcmp source.ini
Manually compare the two files for updates (assuming they are sorted alphabetically; files generated by nvchecker are already sorted):
comm -13 old_ver.txt new_ver.txt # or say that in English: comm -13 old_ver.txt new_ver.txt | awk '{print $1 " has updated to version " $2 "."}' # show both old and new versions join old_ver.txt new_ver.txt | awk '$2 != $3'
The nvtake Command
This command helps to manage version record files. It reads both old and new version record files, and a list of names given on the commandline. It then update the versions of those names in the old version record file.
This helps when you have known (and processed) some of the updated software, but not all. You can tell nvchecker that via this command instead of editing the file by hand.
This command will help most if you specify where you version record files are in your config file. See below for how to use a config file.
Version Source Files
The software version source files are in ini format. Section names is the name of the software. Following fields are used to tell nvchecker how to determine the current version of that software.
See sample_source.ini for an example.
Configuration Section
A special section named __config__ is special, it provides some configuration options[v0.4].
Relative path are relative to the source files, and ~ and environmental variables are expanded.
Currently supported options are:
- oldver
Specify a version record file containing the old version info.
- newver
Specify a version record file to store the new version info.
Search in a Webpage
Search through a specific webpage for the version string. This type of version finding has these fields:
- url
The URL of the webpage to fetch.
- encoding
(Optional) The character encoding of the webpage, if latin1 is not appropriate.
- regex
A regular expression used to find the version string.
It can have zero or one capture group. The capture group or the whole match is the version string.
When multiple version strings are found, the maximum of those is chosen.
- proxy
The HTTP proxy to use. The format is host:port, e.g. localhost:8087. This requires pycurl.
- user_agent
The User-Agent header value to use. Use something more like a tool (e.g. curl/7.40.0) in Europe or the real web page won’t get through because cookie policies (SourceForge has this issue).
Find with a Command
Use a shell command line to get the version. The output is striped first, so trailing newlines do not bother.
- cmd
The command line to use. This will run with the system’s standard shell (i.e. /bin/sh).
Check AUR
Check Arch User Repository for updates.
- aur
The package name in AUR. If empty, use the name of software (the section name).
- strip-release
Strip the release part.
Check GitHub
Check GitHub for updates. The version returned is in date format %Y%m%d, e.g. 20130701.
- github
The github repository, with author, e.g. lilydjwg/nvchecker.
- branch
Which branch to track? Default: master.
- use_latest_release
Set this to true to check for the latest release on GitHub. An annotated tag creates a “release” on GitHub. It’s not the same with git tags, which includes both annotated tags and lightweight ones.
- use_max_tag
Set this to true to check for the max tag on GitHub. Unlike use_latest_release, this option includes both annotated tags and lightweight ones, and return the biggest one sorted by pkg_resources.parse_version.
- ignored_tags
Ignore certain tags while computing the max tag. Tags are separate by whitespaces. This option must be used together with use_max_tag. This can be useful to avoid some known badly versioned tags, so the newer tags won’t be “overridden” by the old broken ones.
An environment variable NVCHECKER_GITHUB_TOKEN can be set to a GitHub OAuth token in order to request more frequently than anonymously.
Check BitBucket
Check BitBucket for updates. The version returned is in date format %Y%m%d, e.g. 20130701.
- bitbucket
The bitbucket repository, with author, e.g. lilydjwg/dotvim.
- branch
Which branch to track? Default is the repository’s default.
- use_max_tag
Set this to true to check for the max tag on BitBucket. Will return the biggest one sorted by pkg_resources.parse_version.
- ignored_tags
Ignore certain tags while computing the max tag. Tags are separate by whitespaces. This option must be used together with use_max_tag. This can be useful to avoid some known badly versioned tags, so the newer tags won’t be “overridden” by the old broken ones.
Check GitCafe
Check GitCafe for updates. The version returned is in date format %Y%m%d, e.g. 20130701.
- gitcafe
The gitcafe repository, with author, e.g. Deepin/deepin-music.
- branch
Which branch to track? Default: master.
Anonymously only. Authorization is not supported yet.
Check GitLab
Check GitLab for updates. The version returned is in date format %Y%m%d, e.g. 20130701.
- gitlab
The gitlab repository, with author, e.g. Deepin/deepin-music.
- branch
Which branch to track? Default: master.
- use_max_tag
Set this to true to check for the max tag on BitBucket. Will return the biggest one sorted by pkg_resources.parse_version.
- ignored_tags
Ignore certain tags while computing the max tag. Tags are separate by whitespaces. This option must be used together with use_max_tag. This can be useful to avoid some known badly versioned tags, so the newer tags won’t be “overridden” by the old broken ones.
- host
Hostname for self-hosted GitLab instance.
- token
GitLab authorization token used to call the API. If not specified, an environment variable NVCHECKER_GITLAB_TOKEN_host must provide that token. The host part is the uppercased version of the host setting, with dots (.) and slashes (/) replaced by underscores (_), e.g. NVCHECKER_GITLAB_TOKEN_GITLAB_COM.
Authenticated only.
Check PyPI
Check PyPI for updates.
- pypi
The name used on PyPI, e.g. PySide.
Check RubyGems
Check RubyGems for updates.
- gems
The name used on RubyGems, e.g. sass.
Check NPM Registry

The name used on NPM Registry, e.g. coffee-script.
Check Hackage
Check Hackage for updates.
- hackage
The name used on Hackage, e.g. pandoc.
Check CPAN
Check MetaCPAN for updates.
- cpan
The name used on CPAN, e.g. YAML.
Check Packagist
Check Packagist for updates.
- packagist
The name used on Packagist, e.g. monolog/monolog.
Check Local Pacman Database
This is used when you run nvchecker on an Arch Linux system and the program always keeps up with a package in your configured repositories for Pacman.
- pacman
The package name to reference to.
- strip-release
Strip the release part.
Check Arch Linux official packages
This enables you to track the update of Arch Linux official packages, without needing of pacman and an updated local Pacman databases.
- archpkg
Name of the Arch Linux package.
- strip-release
Strip the release part.
Check Google Code (hg repository)
Check a mercurial (hg) repository on Google Code for updates. The version returned is in date format %Y%m%d, e.g. 20130701.
- gcode_hg
The name used on Google Code, e.g. chromium-compact-language-detector.
Check Google Code (svn repository)
Check a subversion (svn) repository on Google Code for updates. The version returned is the svn resivion number.
- gcode_svn
The name used on Google Code, e.g. cld2.
Manually updating
This enables you to manually specify the version (maybe because you want to approve each release before it gets to the script).
- manual
The version string.
Version Control System (VCS) (git, hg, svn, bzr)
Check a VCS repo for new commits. The version returned is currently not related to the version of the software and will increase whenever the referred VCS branch changes. This is mainly for Arch Linux.
- vcs
The url of the remote VCS repo, using the same syntax with a VCS url in PKGBUILD (Pacman’s build script). The first VCS url found in the source array of the PKGBUILD will be used if this is left blank. (Note: for a blank vcs setting to work correctly, the PKGBUILD has to be in a directory with the name of the software under the path where nvchecker is run. Also, all the commands, if any, needed when sourcing the PKGBUILD need to be installed).
- use_max_tag
Set this to true to check for the max tag. Currently only supported for git. This option returns the biggest tag sorted by pkg_resources.parse_version.
- ignored_tags
Ignore certain tags while computing the max tag. Tags are separate by whitespaces. This option must be used together with use_max_tag. This can be useful to avoid some known badly versioned tags, so the newer tags won’t be “overridden” by the old broken ones.
