Bump software releases

Installation

• Make sure you are using Python 3.4 or later

• Intall tbump with pip as usual.

Here’s what a typical usage of tbump looks like:

Usage

Create a tbump.toml file looking like:

[version]
current = "1.2.41"
regex = '''
  (?P<major>\d+)
  \.
  (?P<minor>\d+)
  \.
  (?P<patch>\d+)
'''

[git]
message_template = "Bump to {new_version}"
tag_template = "v{new_version}"

[[file]]
src = "setup.py"

Note

• The file uses toml syntax.

• Strings should be templated using curly brackets, to be used with Python’s built-in .format() method.

• The version regular expression will be used in verbose mode and must contain named groups.

Then run:

$ tbump 1.2.42

tbump will:

• Replace the string 1.2.41 by 1.2.42 in every file listed in the configuration

• Make a commit based on the message_template.

• Make an annotated tag based on the tag_template

• Push the current branch and the tag.

Note that by default, tbump will display all the changes and stop to ask if they are correct before performing any action, allowing you to abort and re-try the bump if something is not right.

You can use --non-interactive to disable this behavior.

Advanced configuration

Restricting the lines that are replaced

Sometimes you want to make sure only the line matching a given pattern is replaced. For instance, with the folliwing package.json:

/* in package.json */
{
   "name": "foo",
   "version": "0.42",
   "dependencies": {
     "some-dep": "0.42",
     "other-dep": "1.3",
   }
}

you’ll want to make sure that when you bump from 0.42 to 0.43 that the line containing some-dep does not change.

In this case, you can set a search option in the file section:

# In tbump.toml

[[file]]
src = "package.json"
search = '"version": "{current_version}"'

Using a custom version template

If you are using a version schema like 1.2.3-alpha-4, you may want to expose a variable that only contains the “public” part of the version string. (1.2.3 in this case).

To do so, add a version_template option in te file section. The names used in the format string should match the group names in the regular expression.

/* in version.js */

export FULL_VERSION = '1.2.3-alpha-4';
export PUBLIC_VERSION = '1.2.3';

[[file]]
src = "version.js"
version_template = "{major}.{minor}.{patch}"
search = "export PUBLIC_VERSION = '{current_version}'"

[[file]]
src = "version.js"
search = "export FULL_VERSION = '{current_version}'"

Running commands before push

You can specify a list of hooks to be run after the file have changed, but before the commit is made and pushed.

Here’s an example:

[[hook]]
name = "Check Changelog"
cmd = "grep -q {new_version} Changelog.rst"

The name is mandatory. The command will be executed via the shell, after the {new_version} placehoder is replaced with the new version.

Any hook that fails will interupt the bump. You may want to run git reset --hard before trying again to undo the changes made in the files.
