==========
|
|
- Python 3.5+
|
|
- Python library: structlog
|
|
- One of these Python library combinations (ordered by preference):
|
|
|
|
* tornado + pycurl
|
|
* aiohttp
|
|

|
|
|
Install and Run
|
|
===============
|
|
To install::
|
|
|
|
pip3 install nvchecker
|
|
|
|
To use the latest code, you can also clone this repository and run::
|
|
|
|
python3 setup.py install
|
|
|
|
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.
|
|
|
|
JSON logging
|
|
------------
|
|
With ``--logger=json`` or ``--logger=both``, you can get a structured logging
|
|
for programmatically consuming. You can use ``--json-log-fd=FD`` to specify the
|
|
file descriptor to send logs to (take care to do line buffering). The logging
|
|
level option (``-l`` or ``--logging``) doesn't take effect with this.
|
|
|
|
The JSON log is one JSON string per line. The following documented events and
|
|
fields are stable, undocumented ones may change without notice.
|
|
|
|
event=updated
|
|
An update is detected. Fields ``name``, ``old_version`` and ``version`` are
|
|
available. ``old_version`` maybe ``null``.
|
|
|
|
event=up-to-date
|
|
There is no update. Fields ``name`` and ``version`` are available.
|
|
|
|
event=no-result
|
|
No version is detected. There may be an error. Fields ``name`` is available.
|
|
|
|
level=error
|
|
There is an error. Fields ``name`` and ``exc_info`` may be available to give
|
|
further information.
|
|
|
|
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)`` separated by a space::
|
|
|
|
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.
|
|
|
|
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.
|
|
|
|
proxy
|
|
The HTTP proxy to use. The format is ``proto://host:port``, e.g. ``http://localhost:8087``.
|
|
|
|
max_concurrent
|
|
Max number of concurrent jobs. Default: 20.
|
|
|
|
keyfile
|
|
Specify an ini config file containing key (token) information. This file should contain a ``keys`` section, mapping key names to key values. See specific source for the key name(s) to use.
|
|
|
|
Global Options
|
|
--------------
|
|
The following options apply to all check sources.
|
|
|
|
prefix
|
|
Strip the prefix string if the version string starts with it. Otherwise the
|
|
version string is returned as-is.
|
|
|
|
from_pattern, to_pattern
|
|
Both are Python-compatible regular expressions. If ``from_pattern`` is found
|
|
in the version string, it will be replaced with ``to_pattern``.
|
|
|
|
missing_ok
|
|
Suppress warnings and errors if a version checking module finds nothing.
|
|
Currently only ``regex`` supports it.
|
|
|
|
If both ``prefix`` and ``from_pattern``/``to_pattern`` are used,
|
|
``from_pattern``/``to_pattern`` are ignored. If you want to strip the prefix
|
|
and then do something special, just use ``from_pattern```/``to_pattern``. For
|
|
example, the transformation of ``v1_1_0`` => ``1.1.0`` can be achieved with
|
|
``from_pattern = v(\d+)_(\d+)_(\d+)`` and ``to_pattern = \1.\2.\3``.
|
|
|
|
List Options
|
|
------------
|
|
|
|
The following options apply to sources that return a list. See individual
|
|
source sections to determine whether they are supported.
|
|
|
|
include_regex
|
|
Only consider version strings that match the given regex. The whole string
|
|
should match the regex. Be sure to use ``.*`` when you mean it!
|
|
|
|
exclude_regex
|
|
Don't consider version strings that match the given regex. The whole string
|
|
should match the regex. Be sure to use ``.*`` when you mean it! This option
|
|
has higher precedence that ``include_regex``; that is, if matched by this
|
|
one, it's excluded even it's also matched by ``include_regex``.
|
|
|
|
sort_version_key
|
|
Sort the version string using this key function. Choose between
|
|
``parse_version`` and ``vercmp``. Default value is ``parse_version``.
|
|
``parse_version`` use ``pkg_resources.parse_version``. ``vercmp`` use
|
|
``pyalpm.vercmp``.
|
|
|
|
ignored
|
|
Version strings that are explicitly ignored, separated by whitespace. This
|
|
can be useful to avoid some known mis-named versions, so newer ones won't be
|
|
"overridden" by the old broken ones.
|
|
|
|
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``.
|
|
|
|
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).
|
|
|
|
sort_version_key
|
|
Sort the version string using this key function. Choose between ``parse_version`` and
|
|
``vercmp``. Default value is ``parse_version``. ``parse_version`` use
|
|
``pkg_resources.parse_version``. ``vercmp`` use ``pyalpm.vercmp``.
|
|
|
|
This source supports `list options`_.
|
|
|
|
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 <https://aur.archlinux.org/>`_ for updates.
|
|
|

|
|
|
strip-release
|
|
Strip the release part.

|
path
|
|
Only commits containing this file path will be returned.

|
|
|
use_latest_release
|
|
Set this to ``true`` to check for the latest release on GitHub. An annotated

|
|
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 largest one sorted by the
|
|
``sort_version_key`` option.
|
|
|
|
max_page
|
|
How many pages do we search for the max tag? Default is 1. This works when
|
|
``use_max_tag`` is set.
|
|
|
|
However, with current API in use, GitHub seems to always return all data in
|
|
one page, making this option obsolete.
|
|
|
|
proxy
|
|
The HTTP proxy to use. The format is ``host:port``, e.g. ``localhost:8087``.
|
|
|
|
include_tags_pattern, ignored_tags, sort_version_key
|
|
Deprecated. Use `list options`_ instead.
|
|
|
|
An environment variable ``NVCHECKER_GITHUB_TOKEN`` or a key named ``github``
|
|
can be set to a GitHub OAuth token in order to request more frequently than
|
|
anonymously.
|
|
|
|
This source supports `list options`_ when ``use_max_tag`` is set.
|
|
|
|
Check BitBucket
|
|

|
|
|
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, sort_version_key
|
|
Deprecated. Use `list options`_ instead.
|
|
|
|
max_page
|
|
How many pages do we search for the max tag? Default is 3. This works when
|
|
``use_max_tag`` is set.
|
|
|
|
This source supports `list options`_ when ``use_max_tag`` is set.
|
|
|
|
Check GitLab
|
|
-------------
|
|
Check `GitLab <https://gitlab.com/>`_ 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 GitLab. Will return the biggest one
|
|
sorted by ``pkg_resources.parse_version``.

|
|
Deprecated. Use `list options`_ instead.
|
|
|
|
To set an authorization token, you can set:
|
|
|
|
- a key named ``gitlab_{host}`` in the keyfile (where ``host`` is formed the
|
|
same as the environment variable, but all lowercased).
|
|
- 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``.

|
|
|
|
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.
