Member Function Documentation

◆ after_diagnostic()

void diagnostic_text_output_format::after_diagnostic ( const diagnostic_info & diagnostic )

overridevirtual

Implements diagnostic_output_format.

References path, and print_path().

◆ append_note()

void diagnostic_text_output_format::append_note	(	location_t	location,
		const char *	gmsgid,
			... )


Add a purely textual note with text GMSGID and with LOCATION.

Referenced by maybe_unwind_expanded_macro_loc().

◆ build_indent_prefix()

char * diagnostic_text_output_format::build_indent_prefix ( bool with_bullet ) const

Return a malloc'd string for use as a prefix to show indentation.
If m_show_nesting is false, or we're at the top-level, then the
result will be the empty string.

If m_show_nesting, then the result will contain indentation to show
the nesting level, then either a bullet point (if WITH_BULLET is true),
or a space.

The caller is responsible for freeing the memory.

Referenced by build_prefix(), and on_report_diagnostic().

◆ build_prefix()

char * diagnostic_text_output_format::build_prefix ( const diagnostic_info & diagnostic ) const

Return a malloc'd string describing a location and the severity of the
diagnostic, e.g. "foo.c:42:10: error: ".

If m_show_nesting, then the above will be preceded by indentation to show
the level, and a bullet point.

The caller is responsible for freeing the memory.
