vsketch heavily relies on vpype. Although vpype is automatically installed as a dependency when installing vsketch, it may be useful to review vpype’s installation instructions for additional details and troubleshooting.

Installing using pipx#

The recommended way to install vsketch is using pipx as a stand-alone installation:

$ pipx install vsketch

Running the examples#

Installing vsketch with pipx does not install the examples, and they must be downloaded separately. An archive from the latest version of the vsketch repository can be downloaded here. After decompressing the archive, you can readily execute the examples:

$ vsk run path/to/vsketch-master/examples/schotter

Installing plug-ins#

vsketch is compatible with vpype’s plug-ins. To use plug-ins with vsketch, you must install them inside vsketch virtual environment. In pipx parlance, this is referred to as “injecting”.

For example, run the following command to install vpype-perspective:

$ pipx inject vsketch vpype-perspective


Installing plug-in this way is necessary even if you already have them installed with your current vpype installation. This is due to pipx maintaining isolated environments for each piece of software installed with it.

Installing from the repository#

If you want to make modifications to vsketch itself (regardless of your intention to share them for upstream integration), you must clone the repository and install vsketch from source.

Like vpype, vsketch uses Poetry as project manager. Various methods are available to install Poetry. Using pipx is one of them:

$ pipx install poetry

Once Poetry is installed, clone the repository using git:

$ git clone
$ cd vsketch

From there, Poetry can install everything needed for development environment using a few commands. Though this can be done automatically, it is a good practice to explicitly create a virtual environment by specifying which Python interpreter to use:

$ poetry env use /opt/local/bin/python3.12

This command will create a new virtual environment for the project using the provided Python interpreter (here Python 3.12 as installed by MacPorts on macOS – adjust as needed), and mark it as the default. Note that Poetry can handle any number of virtual environments for the project, for example with different versions of Python. At any time, one of the virtual environment is marked as default and used by other Poetry commands.

Then, everything needed to run vsketch, including what’s needed for development, can be installed with this command:

$ poetry install --with docs

By default, Poetry doesn’t activate the virtual environment, but provides poetry run to execute commands it contains:

$ poetry run vsk run examples/quick_draw

Alternatively, the project’s default virtual environment can be activated using the following command:

$ poetry shell
$ vsk run examples/quick_draw

Poetry is a very powerful tool with many capabilities. Make sure to review its documentation.
