#### Parameters

hint | an AscHint instance. |

### asc_hint_set_tag ()

    void
    asc_hint_set_tag (AscHint *hint,
                      const gchar *tag);

Sets the unique tag for the type of this hint.

#### Parameters

### asc_hint_set_severity ()

    void
    asc_hint_set_severity (AscHint *hint,
                           AsIssueSeverity severity);

Sets the issue severity of this hint.

#### Parameters

hint | an AscHint instance. |

### asc_hint_get_explanation_template ()

    const gchar *
    asc_hint_get_explanation_template (AscHint *hint);

Gets the explanation template for this hint.

#### Parameters

hint | an AscHint instance. |

### asc_hint_set_explanation_template ()

var_name | Name of the variable to be replaced. |
text | Replacement for the variable name. |

### asc_hint_get_explanation_vars_list ()

    GPtrArray *
    asc_hint_get_explanation_vars_list (AscHint *hint);
