Your first code analysis

This article will walk you through your first code analysis with preZero. This process works with applications written using any language preZero supports.

Before you start​

  1. Make sure that the machine on which you're running preZero meets the prerequisites for an optimal experience.
  2. Set up preZero.

Analyzing your code​

Once you've set up your workstation to run preZero, you're ready to submit your code for analysis. To do so, run the following in the command line:

# preZero is capable of inferring from your code repository
# the language in which the code is written, as well as the
# application's name.

sl analyze <path to code>

If no argument is given, the current working directory is used instead:

cd <path to code>
sl analyze

If no language flag is specified, we will decide the language based off of the language detected in most of the files (considering only supported languages), similar to how GitHub and other platforms show this information. The automatic detection can be overridden with any of the language-specific flags.

For example, a project written predominantly in Java will be detected as such and the analysis will proceed accordingly:
