Pyclewn installation notes


Python 2.7 or Python 3.2 or newer.
Vim 7.0 or above with the netbeans_intg feature and the autocmd feature enabled (netbeans and autocmd are enabled on most distributions).

Quick start

A two steps installation.

  1. Install the Python package:

    sudo pip install pyclewn

    This command installs the clewn package and its dependencies.

  2. Install the Vim runtime files with a vimball.

    The vimball is part of the clewn package installed in the first step. First create the pyclewn-2.2.vmb vimball in the current directory with the command:

    python -c "import clewn; clewn.get_vimball()"

    Then source the vimball and install the Vim runtime files with:

    vim -S pyclewn-2.2.vmb

    Type :quit to quit Vim after the vimball is installed.

Installing with pip

The preferred method to install pyclewn is pip, see above. Pip is automatically installed with Python version 3.4 and newer. It is available on most linux distributions as a package and otherwise it is easy to install manually, see pip.

Pip will also install pdb-clone.

Pip will also install trollius and its dependencies on Python 2.7 or on Python versions older than 3.4.

Use a local installation when you do not have root privileges and those are required to install Python packages:

pip install --user pyclewn

Note that on Python 2.7, when the wheel package is installed (which is the case in a virtualenv), the “Failed to build pyclewn” message output by pip should be read instead “Failed to build pyclewn wheel” and must be ignored.

The pyclewn-2.2.vmb vimball is a data file, part of the clewn package, and can be obtained at any time with:

python -c "import clewn; clewn.get_vimball()"

The vimball contains the following runtime files:

autoload/pyclewn/start.vim      # The pyclewn plugin.
autoload/pyclewn/buffers.vim    # Windows management functions.
doc/pyclewn.txt                 # The help.
syntax/clewn_variables.vim      # The (clewn)_variables syntax file.
macros/.pyclewn_keys.gdb        # The 'Cmapkeys' files.

See the vimball documentation with the vim command :help vimball.

Installing from source

Get the tarball from PyPi. Unpack the tarball, change directory to the distribution directory and run the setup script to install pyclewn:

tar xzf pyclewn-2.2.tar.gz
cd pyclewn-2.2
sudo python install

To use Vim as a front-end to the pdb debugger, pyclewn requires that pdb-clone be installed separately. So optionally install pdb-clone from PyPI at pdb-clone.

When the Python version is 2.7 or older than 3.4, you must also install trollius from PyPI at trollius.

Use a local installation when you do not have root privileges and those are required to install Python packages:

python install --user

The runtime files must also be installed as described in the first section. The pyclewn-2.2.vmb vimball can be found in the lib/clewn/runtime directory of the tarball.

Installing from the development version at BitBucket

First install the latest Pyclewn version using one of the methods described above so that the Pyclewn dependencies (pdb-clone, trollius) are satisfied. Then clone pyclewn:

hg clone

Build the source distribution dist/pyclewn-2.2.tar.gz from the root of the workarea:

python sdist

And install it as root:

sudo pip install ---ignore-installed --find-links=dist pyclewn==2.2

Or install it locally using the user scheme:

pip install ---ignore-installed --user --find-links=dist pyclewn==2.2

Finally the Vim run time files must be updated after pip has installed the new version:

python -c "import clewn; clewn.get_vimball()"
vim -S pyclewn-2.2.vmb

Once you have installed a development version, do not forget to use the --ignore-installed option of pip when upgrading later to the latest release, as pip will not upgrade when the installed version is the same as the target version.
