Commands¶
All commands accept a -h/--help
option, which displays the help text for the
command and exits immediately.
semantic-release
does not allow interspersed arguments and options, which
means that the options for semantic-release
are not necessarily accepted
one of the subcommands. In particular, the --noop and
-v/--verbose flags must be given to the top-level
semantic-release
command, before the name of the subcommand.
For example:
Incorrect:
semantic-release version --print --noop -vv
Correct:
semantic-release -vv --noop version --print
With the exception of semantic-release and semantic-release generate-config, all commands require that you have set up your project’s configuration. To help with this step, semantic-release generate-config can create the default configuration for you, which will allow you to tweak it to your needs rather than write it from scratch.
semantic-release
¶
Options:¶
--version
¶
Display the version of Python Semantic Release and exit
--noop
¶
Use this flag to see what semantic-release
intends to do without making changes
to your project. When using this option, semantic-release
can be run as many times
as you wish without any side-effects.
-v/--verbose
¶
Can be supplied more than once. Controls the verbosity of semantic-releases
logging
output (default level is WARNING
, use -v
for INFO
and -vv
for DEBUG
).
-c/--config [FILE]
¶
Specify the configuration file which Python Semantic Release should use. This can be any of the supported formats valid for -f/--format [FORMAT]
Default: pyproject.toml
See also
--strict
¶
Enable Strict Mode. This will cause a number of conditions to produce a non-zero exit code when passed, where they would otherwise have produced an exit code of 0. Enabling this allows, for example, certain conditions to cause failure of a CI pipeline, while omitting this flag would allow the pipeline to continue to run.

semantic-release version
¶
Detect the semantically correct next version that should be applied to your project.
By default:
Write this new version to the project metadata locations specified in the configuration file
Build the project using build_command (Optional[str]), if specified
Create a new commit with these locations and any other assets configured to be included in a release
Tag this commit according the configured format, with a tag that uniquely identifies the version being released
Push the new tag and commit to the remote for the repository
Create a release (if supported) in the remote VCS for this tag
Changelog generation is done identically to the way it is done in semantic-release changelog, but this command additionally ensures the updated changelog is included in the release commit that is made.

Options:¶
--print
¶
Print the next version that will be applied, respecting the other command line options that are supplied, and exit. This flag is useful if you just want to see what the next version will be. Note that instead of printing nothing at all, if no release will be made, the current version is printed.
For example, you can experiment with which versions would be applied using the other command line options:
semantic-release version --print
semantic-release version --patch --print
semantic-release version --prerelease --print
--print-tag
¶
Same as the --print flag but prints the complete tag
name (ex. v1.0.0
or py-v1.0.0
) instead of the raw version number
(1.0.0
).
--print-last-released
¶
Print the last released version based on the Git tags. This flag is useful if you just want to see the released version without determining what the next version will be. Note if the version can not be found nothing will be printed.
--print-last-released-tag
¶
Same as the --print-last-released flag but prints the
complete tag name (ex. v1.0.0
or py-v1.0.0
) instead of the raw version
number (1.0.0
).
--major/--minor/--patch/--prerelease
¶
Force the next version to increment the major, minor or patch digits, or the prerelease revision, respectively. These flags are optional but mutually exclusive, so only one may be supplied, or none at all. Using these flags overrides the usual calculation for the next version; this can be useful, say, when a project wants to release its initial 1.0.0 version.
Warning
Using these flags will override the configured value of prerelease
(configured
in your Release Group),
regardless of your configuration or the current version.
To produce a prerelease with the appropriate digit incremented you should also supply the --as-prerelease flag. If you do not, using these flags will force a full (non-prerelease) version to be created.
For example, suppose your project’s current version is 0.2.1-rc.1
. The following
shows how these options can be combined with --as-prerelease
to force different
versions:
semantic-release version --prerelease --print
# 0.2.1-rc.2
semantic-release version --patch --print
# 0.2.2
semantic-release version --minor --print
# 0.3.0
semantic-release version --major --print
# 1.0.0
semantic-release version --minor --as-prerelease --print
# 0.3.0-rc.1
semantic-release version --prerelease --as-prerelease --print
# 0.2.1-rc.2
These options are forceful overrides, but there is no action required for subsequent releases performed using the usual calculation algorithm.
Supplying --prerelease
will cause Python Semantic Release to scan your project history
for any previous prereleases with the same major, minor and patch versions as the latest
version and the same prerelease token as the
one passed by command-line or configuration. If one is not found, --prerelease
will
produce the next version according to the following format:
f"{latest_version.major}.{latest_version.minor}.{latest_version.patch}-{prerelease_token}.1"
However, if Python Semantic Release identifies a previous prerelease version with the same major, minor and patch digits as the latest version, and the same prerelease token as the one supplied by command-line or configuration, then Python Semantic Release will increment the revision found on that previous prerelease version in its new version.
For example, if "0.2.1-rc.1"
and already exists as a previous version, and the latest version
is "0.2.1"
, invoking the following command will produce "0.2.1-rc.2"
:
semantic-release version --prerelease --prerelease-token "rc" --print
Warning
This is true irrespective of the branch from which "0.2.1-rc.1"
was released from.
The check for previous prereleases “leading up to” this normal version is intended to
help prevent collisions in git tags to an extent, but isn’t foolproof. As the example
shows it is possible to release a prerelease for a normal version that’s already been
released when using this flag, which would in turn be ignored by tools selecting
versions by SemVer precedence rules.
See also
--as-prerelease
¶
After performing the normal calculation of the next version, convert the resulting next version
to a prerelease before applying it. As with --major/--minor/--patch/--prerelease, this option
is a forceful override, but no action is required to resume calculating versions as normal on the
subsequent releases. The main distinction between --prerelease
and --as-prerelease
is that
the latter will not force a new version if one would not have been released without supplying
the flag.
This can be useful when making a single prerelease on a branch that would typically release normal versions.
If not specified in --prerelease-token [VALUE], the prerelease token is idenitified using the Multibranch Release Configuration
See the examples alongside --major/--minor/--patch/--prerelease for how to use this flag.
--prerelease-token [VALUE]
¶
Force the next version to use the value as the prerelease token. This overrides the configured value if one is present. If not used during a release producing a prerelease version, this option has no effect.
--build-metadata [VALUE]
¶
If given, append the value to the newly calculated version. This can be used, for example, to attach a run number from a CI service or a date to the version and tag that are created.
This value can also be set using the environment variable PSR_BUILD_METADATA
For example, assuming a project is currently at version 1.2.3:
$ semantic-release version --minor --print
1.3.0
$ semantic-release version --minor --print --build-metadata "run.12345"
1.3.0+run.12345
--commit/--no-commit
¶
Whether or not to perform a git commit
on modifications to source files made by semantic-release
during this
command invocation, and to run git tag
on this new commit with a tag corresponding to the new version.
If --no-commit
is supplied, it may disable other options derivatively; please see below.
Default: --commit
See also
--tag/--no-tag
¶
Whether or not to perform a git tag
to apply a tag of the corresponding to the new version during this
command invocation. This option manages the tag application separate from the commit handled by the --commit
option.
If --no-tag
is supplied, it may disable other options derivatively; please see below.
Default: --tag
--changelog/--no-changelog
¶
Whether or not to update the changelog file with changes introduced as part of the new version released.
Default: --changelog
--push/--no-push
¶
Whether or not to push new commits and/or tags to the remote repository.
Default: --no-push
if –no-commit and
–no-tag is also supplied, otherwise push
is the default.
--vcs-release/--no-vcs-release
¶
Whether or not to create a “release” in the remote VCS service, if supported. Currently releases in GitHub and Gitea remotes are supported. If releases aren’t supported in a remote VCS, this option will not cause a command failure, but will produce a warning.
Default: --no-vcs-release
if --no-push
is supplied (including where this is
implied by supplying only --no-commit
), otherwise --vcs-release
--skip-build
¶
If passed, skip building the current project using build_command.
semantic-release publish
¶
Publish a distribution to a VCS release. Uploads using [tool.semantic_release.publish]
Options:¶
--tag
¶
The tag associated with the release to publish to. If not given or set to “latest”, then Python Semantic Release will examine the Git tags in your repository to identify the latest version, and attempt to publish to a Release corresponding to this version.
Default: “latest”
semantic-release generate-config
¶
Generate default configuration for semantic-release, to help you get started quickly. You can inspect the defaults, write to a file and then edit according to your needs. For example, to append the default configuration to your pyproject.toml file, you can use the following command:
$ semantic-release generate-config -f toml --pyproject >> pyproject.toml
If your project doesn’t already leverage TOML files for configuration, it might better suit your project to use JSON instead:
$ semantic-release generate-config -f json
If you would like to add JSON configuration to a shared file, e.g. package.json
, you
can then simply add the output from this command as a top-level key to the file.
Note: Because there is no “null” or “nil” concept in TOML (see the relevant
GitHub issue), configuration settings which are None
by default are omitted
from the default configuration.
See also
Options:¶
-f/--format [FORMAT]
¶
The format that the default configuration should be generated in. Valid choices are
toml
and json
(case-insensitive).
Default: toml
--pyproject
¶
If used alongside --format json
, this option has no effect. When using
--format=toml
, if specified the configuration will sit under a top-level key
of tool.semantic_release
to comply with PEP 518; otherwise, the configuration
will sit under a top-level key of semantic_release
.
semantic-release changelog
¶
Generate and optionally publish a changelog for your project. The changelog is generated based on a template which can be customized.
Python Semantic Release uses Jinja as its templating engine; as a result templates need to be written according to the Template Designer Documentation.
See also
Options:¶
--post-to-release-tag [TAG]
¶
If supplied, attempt to find a release in the remote VCS corresponding to the Git tag
TAG
, and post the generated changelog to that release. If the tag exists but no
corresponding release is found in the remote VCS, then Python Semantic Release will
attempt to create one.
If using this option, the relevant authentication token must be supplied via the relevant environment variable. For more information, see Creating VCS Releases.
