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.
