Examples

To generate a diagram with all Crystal files in the src/classes directory:

bin/cruml generate --path="src/classes"

To generate a diagram with one Crystal file:

bin/cruml generate --path="src/classes/my_class.cr"

[!TIP] You can use multiple --path flag to include several files.

In addition, you can change the diagram theme thanks to --dark-mode flag:

bin/cruml generate --path="src/classes" --dark-mode

bin/cruml generate --path="src/classes" --no-color
