Bump

A generic version tracking and update tool.

Bump can be used to automate version updates where other version and package management system does not fit or can't be used. This can be for example when having versions of dependencies in Makefiles, Dockerfiles, scripts or other kinds of texts.

For example this is a Bumpfile where we want to keep the Dockerfile base image version updated to the latest exact alpine 3 version.

$ cat Bumpfile
alpine /FROM alpine:([\d.]+)/ docker:alpine|^3
alpine link "Release notes" https://alpinelinux.org/posts/Alpine-$LATEST-released.html
Dockerfile
# See current versions
$ bump current
Dockerfile:1: alpine 3.9.2
# See possible updates
$ bump check
alpine 3.17.3
# See what will be changed
$ bump diff
--- Dockerfile
+++ Dockerfile

-FROM alpine:3.9.2 AS builder
+FROM alpine:3.17.3 AS builder
 
# Write changes
$ bump update

A real world example is the Dockerfile used by wader/static-ffmpeg where important libraries are automatically kept up to date using the bump github action.

GitHub action

Bump can be used as a github action using the action wader/bump/action@master or by providing it and referencing yourself Here is a workflow that will read Bumpfile and look for new versions and creates PRs once per day at 9 UTC:

name: 'Automatic version updates'
on:
  schedule:
    # minute hour dom month dow (UTC)
    - cron: '0 9 * * *'
  # enable manual trigger of version updates
  workflow_dispatch:
jobs:
  bump:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - uses: wader/bump/action@master
        env:
          GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}

See action.yml for input arguments.

Note that if you want bump PRs to trigger other actions like CI builds you currently have to use a personal access token with repo access and add it as a secret. For example add a secret named BUMP_TOKEN and do GITHUB_TOKEN: ${{ secrets.BUMP_TOKEN }}.

These actions with different environments are available:
wader/bump/action@master alpine with git and curl
wader/bump/action/go@master alpine with git, curl and go

BUMPFILE is a file with CONFIG:s or glob patterns of FILE:s
FILE is a file with EMBEDCONFIG:s or versions to be checked and updated
EMBEDCONFIG is "bump: CONFIG"
CONFIG is
  NAME /REGEXP/ PIPELINE |
  NAME command COMMAND |
  NAME after COMMAND |
  NAME message MESSAGE |
  NAME link TITLE URL
NAME is a configuration name
REGEXP is a regexp with one submatch to find current version
PIPELINE is a filter pipeline: FILTER|FILTER|...
FILTER
  git:<repo> | <repo.git>
  gitrefs:<repo>
  depsdev:<system>:<package>
  docker:<image>
  svn:<repo>
  fetch:<url> | <http://> | <https://>
  semver:<constraint> | semver:<n.n.n-pre+build> | <constraint> | <n.n.n-pre+build>
  re:/<regexp>/ | re:/<regexp>/<template>/ | /<regexp>/ | /<regexp>/<template>/
  sort
  key:<name> | @<name>
  static:<name[:key=value:...]>,...
  err:<error>

Configuration

NAME is a name of the configuration.

REGEXP is a golang regexp with one submatch/capture group to find the current version.

PIPELINE is a pipeline of filters that describes how to find the latest suitable version. The syntax is similar to pipes in a shell filter|filter|... where filter is either in the form name:argument like re:/[\d.]+/, semver:^4 or a shorter form like /[\d.]+/, ^4 etc.

Bumpfile

Default bump looks for a file named Bumpfile in the current directory. Each line is a comment, configuration or a glob pattern of files to read embedded configuration from.

# comment
NAME /REGEXP/ PIPELINE
NAME [command|after] COMMAND
NAME message MESSAGE
NAME link TITLE URL
filename
glob/*

Example Bumpfile:

# a bump configuration
alpine /FROM alpine:([\d.]+)/ docker:alpine|^3
alpine message Make sure to also test with abc
alpine link "Release notes" https://alpinelinux.org/posts/Alpine-$LATEST-released.html
# read configuration, check and update version in Dockerfile
Dockerfile

Embedded

Embedded configuration can be used to include bump configuration inside files containing versions to be checked or updated.

Embedded configuration looks like this:

bump: NAME /REGEXP/ PIPELINE

Example Dockerfile with embedded configuration:

# bump: alpine /FROM alpine:([\d.]+)/ docker:alpine|^3
FROM alpine:3.9.3 AS builder

Run shell command on update

bump: NAME [command|after] COMMAND

COMMAND will run with these environment variables set:
$NAME is configuration name
$CURRENT is current version
$LATEST is latest version available

There are two kinds of shell commands, command and after. command will be executed instead bump doing the changes. after will always be executed after bump has done any changes. If you have multiple commands they will be executed in the same order as they are configured.

Example Bumpfile using command to run go get to change go.mod and go.sum:

module program

go 1.12

require (
  // bump: leaktest /github.com\/fortytw2\/leaktest v(.*)/ git:https://github.com/fortytw2/leaktest.git|^1
  // bump: leaktest command go get -d github.com/fortytw2/leaktest@v$LATEST && go mod tidy
  github.com/fortytw2/leaktest v1.2.0
)

Example Bumpfile using after to run a script to update download hashes:

libvorbis after ./hashupdate Dockerfile VORBIS $LATEST

Commit and pull request messages and links

NAME message MESSAGE
NAME link "TITLE" URL

These variable are available in MESSAGE, TITLE and URL:
$NAME is configuration name
$CURRENT is current version
$LATEST is latest version available

You can include messages and links in commit messages and pull requests by using one or more message and link configurations.

Example:

libvorbis link "CHANGES file" https://github.com/xiph/vorbis/blob/master/CHANGES
libvorbis link "Source diff $CURRENT..$LATEST" https://github.com/xiph/vorbis/compare/v$CURRENT..v$LATEST

Pipeline

A pipeline consist of one or more filters executed in sequence. Usually it starts with a filter that produces versions from some source like a git repository. After that one or more filters can select, transform and sort versions to narrow it down to one version. If a pipeline ends up producing more than one version the first will be used.

A version is a dictionary of key/value pairs, the "name" key is either the version number like "1.2.3" or some symbolic name like "master". In addition a version can have other keys like "commit", "version" etc depending on the source. You can use the key filter key:<name> or @<name> to use them.

Default all filters operate on the default key which is the "name". This can be changed along a pipeline using key:<name> or @<name>.

Examples

In the examples bump pipeline PIPELINE is used to test run a pipeline and show the result. Use bump -v pipeline PIPELINE for even more verbose output that can be helpful when testing pipelines.

# Latest 4.0 ffmpeg version
$ bump pipeline 'https://github.com/FFmpeg/FFmpeg.git|^4'
4.4.4
# Commit hash of the latest 4.0 ffmpeg version
$ bump pipeline 'https://github.com/FFmpeg/FFmpeg.git|^4|@commit'
c1738cdff0d3b6426f3e6fd9bf25af7d145ad26f
# Latest 1.0 golang docker build image
$ bump pipeline 'docker:golang|^1'
1.20.3
# Latest mp3lame version
$ bump pipeline 'svn:http://svn.code.sf.net/p/lame/svn|/^RELEASE__(.*)$/|/_/./|*'
3.100

Filters

Filter are used to produce, transform and filter versions. Some filters like git produces versions, re and semver transforms and filters.

git git:<repo> or <repo.git>
gitrefs gitrefs:<repo>
depsdev depsdev:<system>:<package>
docker docker:<image>
svn svn:<repo>
fetch fetch:<url>, <http://> or <https://>
semver semver:<constraint>, semver:<n.n.n-pre+build>, <constraint> or <n.n.n-pre+build>
re re:/<regexp>/, re:/<regexp>/<template>/, /<regexp>/ or /<regexp>/<template>/
sort sort
key key:<name> or @<name>
static static:<name[:key=value:...]>,...
err err:<error>

git

git:<repo> or <repo.git>

Produce versions from tags for a git repository. Name will be the version found in the tag, commit the commit hash or tag object.

Use gitrefs filter to get all refs unfiltered.

$ bump pipeline 'https://github.com/git/git.git|*'
2.40.0

gitrefs

gitrefs:<repo>

Produce versions from all refs for a git repository. Name will be the whole ref like "refs/tags/v2.7.3" and commit will be the commit hash.

Use git filter to get versions from only tags.

$ bump pipeline 'gitrefs:https://github.com/git/git.git'
HEAD

depsdev

depsdev:<system>:<package>

Produce versions from https://deps.dev.

Supported package systems npm, go, maven, pypi and cargo.

$ bump pipeline 'depsdev:npm:react|*'
18.2.0
$ bump pipeline 'depsdev:go:golang.org/x/net'
0.0.0-20180926154720-4dfa2610cdf3
$ bump pipeline 'depsdev:maven:log4j:log4j|^1'
1.2.17
$ bump pipeline 'depsdev:pypi:av|*'
10.0.0
$ bump pipeline 'depsdev:cargo:serde|*'
1.0.160

docker

docker:<image>

Produce versions from a image on ducker hub or other registry. Currently only supports anonymous access.

$ bump pipeline 'docker:alpine|^3'
3.17.3
$ bump pipeline 'docker:mwader/static-ffmpeg|^4'
4.4.1
$ bump pipeline 'docker:ghcr.io/nginx-proxy/nginx-proxy|^0.9'
0.9.3

svn

svn:<repo>

Produce versions from tags and branches from a subversion repository. Name will be the tag or branch name, version the revision.

$ bump pipeline 'svn:https://svn.apache.org/repos/asf/subversion|*'
1.14.2

fetch

fetch:<url>, <http://> or <https://>

Fetch a URL and produce one version with the content as the key "name".

$ bump pipeline 'fetch:http://libjpeg.sourceforge.net|/latest release is version (\w+)/'
6b

semver

semver:<constraint>, semver:<n.n.n-pre+build>, <constraint> or <n.n.n-pre+build>

Use semver to filter or transform versions.

When a constraint is provided it will be used to find the latest version fulfilling the constraint.

When a verison pattern is provied it will be used to transform a version.

# find latest major 1 version
$ bump pipeline 'static:1.1.2,1.1.3,1.2.0|semver:^1'
1.2.0
# find latest minor 1.1 version
$ bump pipeline 'static:1.1.2,1.1.3,1.2.0|~1.1'
1.1.3
# transform into just major.minor
$ bump pipeline 'static:1.2.3|n.n'
1.2

re

re:/<regexp>/, re:/<regexp>/<template>/, /<regexp>/ or /<regexp>/<template>/

An alternative regex/template delimited can specified by changing the first / into some other character, for example: re:#regexp#template#.

Filter name using a golang regexp. If name does not match regexp the version will be skipped.

If only a regexp and no template is provided and no submatches are defined the name will not be changed.

If submatches are defined a submatch named "name" or "value" will be used as name and value otherwise first submatch will be used as name.

If a template is defined and no submatches was defined it will be used as a replacement string. If submatches are defined it will be used as a template to expand $0, ${1}, $name etc.

A regexp can match many times. Use ^$ anchors or (?m:) to match just one time or per line.

# just filter
$ bump pipeline 'static:a,b|/b/'
b
# simple replace
$ bump pipeline 'static:aaa|re:/a/b/'
bbb
# simple replace with # as delimiter
$ bump pipeline 'static:aaa|re:#a#b#'
bbb
# name as first submatch
$ bump pipeline 'static:ab|re:/a(.)/'
b
# multiple submatch replace
$ bump pipeline 'static:ab:1|/(.)(.)/${0}$2$1/'
abba
# named submatch as name and value
$ bump pipeline 'static:ab|re:/(?P<name>.)(?P<value>.)/'
a
$ bump pipeline 'static:ab|re:/(?P<name>.)(?P<value>.)/|@value'
b

sort

sort

Sort versions reverse alphabetically.

$ bump pipeline 'static:a,b,c|sort'
c

key

key:<name> or @<name>

Change default key for a pipeline. Useful to have last in a pipeline to use git commit hash instead of tag name etc or in the middle of a pipeline if you want to regexp filter on something else than name.

$ bump pipeline 'static:1.0:hello=world|@hello'
world
$ bump pipeline 'static:1.0:hello=world|@name'
1.0
$ bump pipeline 'static:1.0:hello=world|key:hello'
world

static

static:<name[:key=value:...]>,...

Produce versions from filter argument.

$ bump pipeline 'static:1,2,3,4:key=value:a=b|sort'
4

err

err:<error>

Fail with error message. Used for testing.

$ bump pipeline 'err:test'
test
