Existing text output in GCC has to be implemented by writing sequentially to a pretty_printer instance. This makes it hard to implement some kinds of diagnostic output (see e.g. diagnostic-show-locus.cc). This patch adds more flexible ways of creating text output: - a canvas class, which can be "painted" to via random-access (rather that sequentially) - a table class for 2D grid layout, supporting items that span multiple rows/columns - a widget class for organizing diagrams hierarchically. The patch also expands GCC's diagnostics subsystem so that diagnostics can have "text art" diagrams - think ASCII art, but potentially including some Unicode characters, such as box-drawing chars. The new code is in a new "gcc/text-art" subdirectory and "text_art" namespace. The patch adds a new "-fdiagnostics-text-art-charset=VAL" option, with values: - "none": don't emit diagrams (added to -fdiagnostics-plain-output) - "ascii": use pure ASCII in diagrams - "unicode": allow for conservative use of unicode drawing characters (such as box-drawing characters). - "emoji" (the default): as "unicode", but potentially allow for conservative use of emoji in the output (such as U+26A0 WARNING SIGN). I made it possible to disable emoji separately from unicode as I believe there's a generation gap in acceptance of these characters (some older programmers have a visceral reaction against them, whereas younger programmers may have no problem with them). Diagrams are emitted to stderr by default. With SARIF output they are captured as a location in "relatedLocations", with the diagram as a code block in Markdown within a "markdown" property of a message. This patch doesn't add any such diagram usage to GCC, saving that for followups, apart from adding a plugin to the test suite to exercise the functionality. contrib/ChangeLog: * unicode/gen-box-drawing-chars.py: New file. * unicode/gen-combining-chars.py: New file. * unicode/gen-printable-chars.py: New file. gcc/ChangeLog: * Makefile.in (OBJS-libcommon): Add text-art/box-drawing.o, text-art/canvas.o, text-art/ruler.o, text-art/selftests.o, text-art/style.o, text-art/styled-string.o, text-art/table.o, text-art/theme.o, and text-art/widget.o. * color-macros.h (COLOR_FG_BRIGHT_BLACK): New.
