Wrapper around pip commands to auto save/delete requirements

Project description

# pipm

Python package management workflow using pip & requirements file as its metadata. (For the time being until `Pipfile`
is mature.)

# Installation

Install from PyPI

```
pip install pipm
```

Or Install directly from the GitHub

```commandline
pip install -e git://github.com/jnoortheen/pipm.git@master#egg=pipm
```

# Quickstart
All `pip` commands will work as it is, plus they will be saved to the requirements file. Both `pip` and `pipm` command
will work as the same. For some reason, if the pip command is not overridden, you could always rely on `pipm`.

## warning
- the `pip` command will be replaced by the one that comes with this package. There is no functionality gets
affected other than manipulating the requirements files. So when you uninstall `pipm` the `pip` command will also get removed. To remedy this, just install `pip` again using `easy_install pip`
- this tool manipulates all your requirements file. So be sure to use version control software or take backup of your files to keep track of changes.

### installation
```pipm install pkg-name``` or
```pip install pkg-name```

### installation as development dependency
```pipm install pkg-name --dev```


### installation as testing dependency
```pipm install pkg-name --test```

### removal
```pipm uninstall pkg-name```

### update all your dependencies
```pipm update```

### install all your dependencies from the requirements file
```pipm install```

### including development dependencies
```pipm install --dev```


# Usage

1. install
- a wrapper around standard `pip install` command and accepts all the standard options

Below are the things that `pipm` brings to the table

1. Extra functionality
- when package names are given it will be saved to the requirements.txt file in the current directory.
If you have `requirements` directory structure with `base.txt` inside then that file will be used. Otherwise it
will create one in the current directory.
- when no package name is given then it is equivalent to `-r requirements.txt` and it will install all requirements
from the current directory
1. Additional options:
the below saves to file when package name given otherwise equivalent to passing requirements file name.
1. `--dev` - saves to development requirements
1. `--prod` - saves to production requirements
1. `--test` - saves to testing requirements
1. `--env <name>` - if you have any special set of requirements that belong to a separate file you could pass the name here.
It will search for the matching one in the following pattern `<name>-requirements.txt` or
`requirements/<name>.txt` or `requirements-<name>.txt`

1. uninstall
- a wrapper around standard `pip uninstall` command
- alias `rm` is available
- when uninstalling a package, this command also checks packages that are no longer required by any of the installed
packages and removes them
- ofcourse it removes the packages from `requirements` files

1. update
- new command
- equivalent to calling `pip install` with `--upgrade` flag
- update a single package or the whole environment when no argument given.
- by default the packages are updated interactively
- set `--auto-update` to disable this

1. save/freeze
- extends the standard freeze command to save the currently installed packages


# Features

1. Just a wrapper around the standard pip's `install` & `uninstall` command. So all the cli options will work
1. Handles multiple `requirements` files

# Development
- clone the repository and create new virtualenv

```
git clone git@github.com:jnoortheen/pipm.git
cd pipm
pew new pipm -a .
```

- install development requirements
```
pip install -r dev-requirements.txt
```

- to test from local sources
```
pip install -e .
```

# Testing

- After installing `text-requirements.txt` just run `invoke test` from the root directory.

# version compatibility
the package is versioned in accordance with `pip`. `pipm-9.*` will be compatible with `pip-9` and so on.
