env_cwd

The module sets the working directory. It also checks that directory exists and is writable. If the directory is missing it is created with all the intermediate folders.

The cwd affects the following modules: cmd_save, save_pickle, save_root, save_yaml, graphviz_v1, and mpl_v1.

Positional arguments

• cwd – defines the path of the working directory that shall be set

Options

• -p, --prefix – defines the prefix of all files that are saved to the cwd by GNA

• -d, --print, --dump – print list of processed paths to console

Examples

• Set the current working directory to ‘output/test-cwd’:

  ./gna \
     -- env-cwd output/test-cwd
  

  From this moment all the output files will be saved to ‘output/test-cwd’.

• An arbitrary prefix may be prepended to the filenames with -p option:

  ./gna \
      -- env-cwd output/test-cwd -p prefix-
  

• Print list of all previously saved files:

  ./gna \
      -- env-cwd -d
