[PATCH 1/3] tools/utils: cleanup formatting of libxlutil.h

[Elliott Mitchell]

Date: Mon, 10 Jul 2023 15:55:30 -0700

Some arguments included a name, but not all did.  Now use "cfg" for
all uses of XLU_Config * and "list" for uses of XLU_ConfigList *.

Also fix some spaces missing from xlu_cfg_get_defbool()'s prototype.

Rename the "b" argument of xlu_cfg_get_defbool() to "value_r".  Similar
to other functions this is where the returned value is stored.

[PATCH 0/3] Some cleanup of tools utility library

[Elliott Mitchell]

These have been hanging around in my repository for a while.  The
original submission pass got bungled and other things came up.  Simply
some small bits of formatting cleanup.

Elliott Mitchell (3):
  tools/utils: cleanup formatting of libxlutil.h
  tools/utils: rename "n" arguments to "key"
  tools/utils: remove old declaration of xlu__cfg_yyparse()

[PATCH 3/3] tools/utils: remove old declaration of xlu__cfg_yyparse()

[Elliott Mitchell]

Date: Wed, 26 Jul 2023 21:09:21 -0700

This was added at b104c3762dc.  Appears this was fixed in the intervening
decade.  Otherwise this could have been an issue from using advanced
features of Bison.  Now this appears unnecessary.

[PATCH 2/3] tools/utils: rename "n" arguments to "key"

[Elliott Mitchell]

Date: Wed, 12 Jul 2023 23:29:59 -0700

Hopefully make it clearer to others this is the key associated with the
storage value to retrieve.
