Developing on Windows

To download the latest version of Plaso you’ll need to install the git tools:

Checkout the plaso source from the git repo:

git clone

If you intend to submit code make sure to configure git to use convert to the Unix-style end-of-line characters (linefeed) on submission and not have the Windows-style end-of-line characters (carriage return + linefeed).

We recommend to configure your editor of choice to use linefeed only and turn off git’s autocrlf:

git config --global core.autocrlf false

To be able to run the plaso development release on Windows you’ll have to have installed the dependencies.

Check if you have all the dependencies installed and have the right minimum version:

C:\Python27\python.exe utils\

Note that some dependencies are actively under development and can be frequently updated, therefore we recommend checking the status of the dependencies regularly.

Running the development release

To run the development release directly from source make sure Python can find the plaso source files by setting PYTHONPATH correspondingly.

set PYTHONPATH=C:\plaso-build\plaso

To run e.g. pinfo:

C:\Python27\python.exe C:\plaso-build\plaso\plaso\frontend\ plaso.db

Development tools

If you intend to do development on plaso you’ll also need to install some development tools:

  • PyLint
  • Python Mock


At the moment Plaso development requires PyLint 1.6.x.

TODO: describe building pylint 1.6.x

For pylint 1.6.x the following additional dependencies are required:


Python Mock

Download the latest source package from:

To build the MSI file run the following commands from the build root directory:

tar xvf mock-1.0.1.tar.gz
cd mock-1.0.1\
C:\Python27\python.exe bdist_msi
cd ..

This will create a MSI in the dist sub directory e.g.:


Install the MSI.
