Add a note to the readme file to clarify that the default build system is still automake. Signed-off-by: Tim Wiederhake <twied@gmx.net>
2024-03-07Provide defaults for externally defined symbolsTim Wiederhake
AM_CPPFLAGS defines several symbols that do not have to be there. By providing default values in twm.h, this list can be reduced in size while still allowing to override these values. Signed-off-by: Tim Wiederhake <twied@gmx.net>
2024-03-07Remove version.c and version.hTim Wiederhake
These files define only a single variable that is used in only one place. Signed-off-by: Tim Wiederhake <twied@gmx.net>

2024-03-05improve declaration of yylex()Thomas E. Dickey
Replace the extern declaration of yylex() in gram.y with a definition/use in parse.h, improving portability. Signed-off-by: Thomas E. Dickey <dickey@invisible-island.net>
2024-03-05amend yylineno changeThomas E. Dickey
A recent change removed the declaration of yylineno from lex.l, making the program depend on the version of flex. Restore the declaration with an ifdef. Also, remove unused declaration in parse.c Signed-off-by: Thomas E. Dickey <dickey@invisible-island.net>
2024-03-05include "gram.h" only from "parse.h"Thomas E. Dickey
all of the users of (generated) gram.h rely upon (custom) parse.h, and the order of those headers affects portability. Signed-off-by: Thomas E. Dickey <dickey@invisible-island.net>

2024-01-20Rework dummy variable usage in ExecuteFunctionTim Wiederhake
twm defines several "junk" variables to use with functions like XQueryPointer or XGetGeometry. In some instances, the returned values are actually used, which makes the code confusing and hard to reason about. Use dedicated variables in those cases. Signed-off-by: Tim Wiederhake <twied@gmx.net>
