Installation

pipx install pip-split-requirements

Quick start

Assume the following requirements.txt:

--find-links wheelhouse
pkga
git+https://github.com/some/project
pkgb

Running

pip-split-requirements -g slow:git requirements.txt

Will create requirementsgroup-slow.txt:

--find-links wheelhouse
git+https://github.com/some/project

and requirementsgroup-other.txt:

--find-links wheelhouse
pkga
pkgb

CLI Usage

Usage: pip-split-requirements [OPTIONS] REQUIREMENTS_FILE...

  Split a pip requirements file into multiple files according to patterns.

  Patterns are regular expressions against which requirement lines are
  searched to determine if they belong to a group. Group specs are evaluated
  in order, and the first match determines in which group the line goes.

  Comment lines are ignored.

  Option lines are emitted in all groups.

Arguments:
  REQUIREMENTS_FILE...  The requirements files to split. If not specified,
                        they are read from pyproject.toml.

Options:
  -g, --group-spec TEXT           Group specifications in form name:pattern.
  -p, --prefix TEXT               Each requirements group file will be named
                                  {prefix}-{group_name}.txt. The prefix can
                                  contain path separators, to generate files
                                  into a chosen directory.  [default:
                                  requirementsgroup]
  --default-group / --no-default-group
                                  Automatically append a group named 'other',
                                  matching all lines not matched by other
                                  groups.  [default: default-group]
  --remove-empty / --no-remove-empty
                                  Remove empty requirements group files.
                                  [default: no-remove-empty]
  -r, --project-root DIRECTORY    The project root directory. The generated
                                  requirements files will be relative to this
                                  directory. Default options and arguments are
                                  read from pyproject.toml in this directory.
                                  [default: .]
  --install-completion [bash|zsh|fish|powershell|pwsh]
                                  Install completion for the specified shell.
  --show-completion [bash|zsh|fish|powershell|pwsh]
                                  Show completion for the specified shell, to
                                  copy it or customize the installation.
  --help                          Show this message and exit.

Configuration in pyproject.toml

pip-split-requirements can be configured using pyproject.toml. The following values are read from the tool.pip-split_requirements section:

• group_specs: list of strings
• prefix: string
• default_group: boolean
• remove_empty: boolean
• requirements_files: list of strings

Command line options and argument have precedence over pyproject.toml values.

The following example configuration split requirements.txt and requirements-test.txt into a group named vcs with requirements containing the word git+https or git+ssh and another group with everything else, as build/reqgroup-*.txt.

[tool.pip-split-requirements]
prefix = "build/reqgroup"
group_specs = ["vcs:git.(https|ssh)"]
requirements_files = ["requirements.txt", "requirements-test.txt"]

Usage as a pre-commit hook

The following section of .pre-commit-config.yaml will run pip-split-requirements according using the configuration in pyproject.toml. This pre-commit hook runs when either pyproject.toml, .pre-commit-config.yaml, or any file matching the pattern .*requirement.*\.txt change.
