Like below. This was probably what Cagney had in mind with
the "FIXME: make these enum commands". Notice how set_case_str, set_type_str,
set_range_str and set_lang_str go away. This kills a few more usages of
deprecated_show_value_hack. No need to strip trailing whitespace.
One issue is that "set language" without an argument doesn't show that
larger help list of known languages, because the enum command machinary
takes care of handling the case of no argument itself. I've moved that
listing to "help set language", which I think is a better place for it
anyway.
(gdb) set language
Requires an argument. Valid arguments are auto, local, unknown, ada, c, c++, asm, minimal, fortran, objective-c, java, modula-2, pascal, scheme.
(gdb) help set language
Set the current source language.
The currently understood settings are:
local or auto Automatic setting based on source file
ada Use the Ada language
c Use the C language
c++ Use the C++ language
asm Use the Asm language
minimal Use the Minimal language
fortran Use the Fortran language
objective-c Use the Objective-c language
java Use the Java language
modula-2 Use the Modula-2 language
pascal Use the Pascal language
scheme Use the Scheme language
(gdb)
This required a couple of testsuite adjustments to default.exp
and help.exp. I diffed the log of running setshow.exp, and the only
differences that came out were "Warning" vs "warning". This is due
to the patch changing a few printf_unfiltered("Warning:..." calls
to warning(_("... calls. More consistency, and, added i18n.
No regressions on x86_64-unknown-linux-gnu. Let me know what
you think.

* language.c (language, type, range, case_sensitive): Make const.
(show_language_command): Don't call deprecated_show_value_hack.
Special case "auto".
(set_language_command): Don't strip trailing whitespace. Don't
print list of known languages. An unrecognized language is now an
internal error instead of a user error. Don't call set_lang_str.
(language_completer): Delete.
(show_type_command): Don't call deprecated_show_value_hack.
Special case "auto". Use warning.
(set_type_command): Don't strip trailing whitespace. An
unrecognized type is now an internal error instead of a user
error. Output type check mismatch with language here. Don't call
set_type_str.
(show_range_command): Don't call deprecated_show_value_hack.
Special case "auto". Use warning.
(set_range_command): Don't strip trailing whitespace. An
unrecognized range check is now an internal error instead of a
warning. Output range check mismatch with language here. Don't
call set_range_str.
(show_case_command): Don't call deprecated_show_value_hack.
Special case "auto". Use warning.
(set_case_command): Don't call set_case_str. An unrecognized case
check is now an internal error instead of a warning. Output range
check mismatch with language here. Don't call set_case_str.
(set_type_range_case): Don't call set_type_str, set_range_str or
set_case_str here.
(set_lang_str, set_type_str, set_range_str, set_case_str): Delete.
(add_language): Install or reinstall the "set language" command
here, and make it an enum command. Build the enumeration and the
help string from the current list of known languages.
(_initialize_language): Don't install "set language" here. Make
"set check type", "set check range" and "set case-sensitive" enum
commands. Register the "auto" "local" and "unknown" languages in
that order.
2009-08-08 Pedro Alves <pedro@codesourcery.com>
* gdb.base/default.exp: Adjust "set language test": it's now an
enum command. Larger help string moved to "help set language".
* gdb.base/help.exp: Adjust "help set language" expected output,
now lists all known languages.
