Detailed Description

A subclass of pretty_printer for implementing dump_context::dump_printf_va.
In particular, the formatted chunks are captured as optinfo_item instances
as pp_token_custom_data, thus retaining metadata about the entities being
dumped (e.g. source locations), rather than just as plain text.
These custom items are retained through to the end of stage 3 of formatted
printing; the printer uses a custom token_printer subclass to emit them to
the active optinfo (if any).

Member Function Documentation

◆ begin_url()

void pretty_printer::begin_url ( const char * url)
inherited
Support for encoding URLs.
See egmontkob/Hyperlinks_in_Terminal_Emulators.md
( https://gist.github.com/egmontkob/eb114294efbcd5adb1944c9f3cb5feda ).

> A hyperlink is opened upon encountering an OSC 8 escape sequence with

Use BEL instead of ST, as that is currently rendered better in some
terminal emulators that don't support OSC 8, like konsole.   
If URL-printing is enabled, write an "open URL" escape sequence to PP
for the given URL.

◆ clear_state()

void pretty_printer::clear_state ( )
inlineinherited
Clear this pretty_printer's output state.

◆ decode_format()

bool dump_pretty_printer::decode_format ( text_info * text,
const char * spec,
pp_token_list & formatted_tok_list )
private
Format decoder for dump_pretty_printer, and thus for dump_printf and
dump_printf_loc.

Supported format codes (in addition to the standard pretty_printer ones)
are:

%C: cgraph_node *:
    Equivalent to: dump_symtab_node (MSG_*, node)
%E: gimple *:
    Equivalent to: dump_gimple_expr (MSG_*, TDF_SLIM, stmt, 0)
%G: gimple *:
    Equivalent to: dump_gimple_stmt (MSG_*, TDF_SLIM, stmt, 0)
%T: tree:
    Equivalent to: dump_generic_expr (MSG_*, arg, TDF_SLIM).

TODO: add a format code that can handle (symtab_node*) *and* both
subclasses (presumably means teaching -Wformat about non-virtual
subclasses).

These format codes build optinfo_item instances, thus capturing metadata
about the arguments being dumped, as well as the textual output.
