Implement help/show values for 'set|show style'.
Currently, the behaviour is: (gdb) show style (gdb) set style (gdb) show style address (gdb) set style address (gdb) With this patch, the behaviour is: (gdb) show style style address background: The "address" background color is: none style address foreground: The "address" foreground color is: blue style address intensity: The "address" display intensity is: normal enabled: CLI output styling is enabled. style filename background: The "filename" background color is: none style filename foreground: The "filename" foreground color is: green style filename intensity: The "filename" display intensity is: normal style function background: The "function" background color is: none style function foreground: The "function" foreground color is: yellow style function intensity: The "function" display intensity is: normal style variable background: The "variable" background color is: none style variable foreground: The "variable" foreground color is: cyan style variable intensity: The "variable" display intensity is: normal (gdb) set style "set style" must be followed by an appropriate subcommand. List of set style subcommands: set style address -- Address display styling set style enabled -- Set whether CLI styling is enabled set style filename -- Filename display styling set style function -- Function name display styling set style variable -- Variable name display styling Type "help set style" followed by set style subcommand name for full documentation. Type "apropos word" to search for commands related to "word". Command name abbreviations are allowed if unambiguous. (gdb) show style address background: The "filename" background color is: none foreground: The "filename" foreground color is: green intensity: The "filename" display intensity is: normal (gdb) set style address List of set style address subcommands: set style address background -- Set the background color for this property set style address foreground -- Set the foreground color for this property set style address intensity -- Set the display intensity color for this property Type "help set style address" followed by set style address subcommand name for full documentation. Type "apropos word" to search for commands related to "word". Command name abbreviations are allowed if unambiguous. (gdb) gdb/ChangeLog * cli/cli-style.h (class cli_style_option): <add_setshow_commands> Remove arg prefixname, add do_set and do_show. Add member functions set_list and show_list. * cli/cli-style.c (class cli_style_option): Update accordingly. (style_set_list): Move to file scope. (style_show_list): Likewise. (set_style): Call help_list. (show_style): Call cmd_show_list. (_initialize_cli_style): New macro STYLE_ADD_SETSHOW_COMMANDS. Update to use the new macro.
