Configuration

Some parameters can be configured before importing this script. When installing the script, a default configuration file .cfg_dynamic_prompt is created in the $HOME folder with a sample (default) configuration.

Configurable variables

1. DYN_PROMPT_BRANCH_COLOR is an array or color numbers for branch names. By default, branch names are taken from git flow. Real, visual color might change depending on terminal configuration.

2. DYN_PROMPT_BRANCH_DEFAULT_COLOR is the color number used when the branch name does not match any of the predefined names in the previous array.

3. DYN_PROMPT_BRANCH_STATUS is an array of colors and symbols to indicate the current status.

4. DYN_PROMPT_BRANCH_SEPARATOR is a string used as a separator between your prompt and the branch indicator.

5. DYN_PROMPT_BRANCH_BEGIN and DYN_PROMPT_BRANCH_END are two characters used to wrap the branch+status indicator, usually [ and ], ( and ) ...

6. DYN_PROMPT_SCHEME is number that determines the prompt scheme to use. For the moment only 2 schemes are available: default and #1.

7. DYN_SEPARATOR_CHAR is the character (and color) used to separate the prompt from the previous output in some of the prompt schemes.

Probably you will need some experimentation with these variables to suite your taste. For example, you might prefer:

    DYN_PROMPT_BRANCH_SEPARATOR=" | "
    DYN_PROMPT_BRANCH_BEGIN=" "
    DYN_PROMPT_BRANCH_END=" "

Prompt schemes

For the moment there are only 2 available schemes: default and #1.
