+## Formatting
+
+Cpptrace provides a configurable formatter for stack trace printing supporting common options. Formatters are configured
+following a sort of builder pattern, e.g.
+```cpp
+auto formatter = cpptrace::formatter{}
+    .header("Stack trace:")
+    .addresses(cpptrace::formatter::address_mode::object)
+    .snippets(true);
+```
+
+To use this API be sure to `#include <cpptrace/formatting.hpp>`.
+
+Synopsis:
+```cpp
+namespace cpptrace {
+    class formatter {
+        formatter& header(std::string);
+        enum class color_mode { always, none, automatic };
+        formatter& colors(color_mode);
+        enum class address_mode { raw, object, none };
+        formatter& addresses(address_mode);
+        enum class path_mode { full, basename };
+        formatter& paths(path_mode);
+        formatter& snippets(bool);
+        formatter& snippet_context(int);
+        formatter& columns(bool);
+        formatter& filtered_frame_placeholders(bool);
+        formatter& filter(std::function<bool(const stacktrace_frame&)>);
+
+        std::string format(const stacktrace_frame&) const;
+        std::string format(const stacktrace_frame&, bool color) const;
+
+        std::string format(const stacktrace&) const;
+        std::string format(const stacktrace&, bool color) const;
+
+        void print(const stacktrace_frame&) const;
+        void print(const stacktrace_frame&, bool color) const;
+        void print(std::ostream&, const stacktrace_frame&) const;
+        void print(std::ostream&, const stacktrace_frame&, bool color) const;
+        void print(std::FILE*, const stacktrace_frame&) const;
+        void print(std::FILE*, const stacktrace_frame&, bool color) const;
+
+        void print(const stacktrace&) const;
+        void print(const stacktrace&, bool color) const;
+        void print(std::ostream&, const stacktrace&) const;
+        void print(std::ostream&, const stacktrace&, bool color) const;
+        void print(std::FILE*, const stacktrace&) const;
+        void print(std::FILE*, const stacktrace&, bool color) const;
+    };
+}

+| `filter`                      | A predicate to filter frames with                              | None                                                                     |
+
+The `automatic` color mode only works for a stream that may be attached to a terminal, e.g. `cout` or `stdout`,
+`formatter::format` and `formatter::print` methods have overloads taking a color parameter. This color parameter will
+override configured color mode.
+
+Recommended practice with formatters: It's generally preferable to create formatters objects that are long-lived rather
+than to create them on the fly every time a trace needs to be formatted.
+
+Cpptrace provides access to a formatter with default settings with `get_default_formatter`:
+```cpp
+namespace cpptrace {
+    const formatter& get_default_formatter();
+}
+```
