This is an extremely extensive patch as it hits every cvar, and every
usage of the cvars. Cvars no longer store the value they control,
instead, they use a cexpr value object to reference the value and
specify the value's type (currently, a null type is used for strings).
Non-string cvars are passed through cexpr, allowing expressions in the
cvars' settings. Also, cvars have returned to an enhanced version of the
original (id quake) registration scheme.
As a minor benefit, relevant code having direct access to the
cvar-controlled variables is probably a slight optimization as it
removed a pointer dereference, and the variables can be located for data
locality.
The static cvar descriptors are made private as an additional safety
layer, though there's nothing stopping external modification via
Cvar_FindVar (which is needed for adding listeners).
While not used yet (partly due to working out the design), cvars can
have a validation function.
Registering a cvar allows a primary listener (and its data) to be
specified: it will always be called first when the cvar is modified. The
combination of proper listeners and direct access to the controlled
variable greatly simplifies the more complex cvar interactions as much
less null checking is required, and there's no need for one cvar's
callback to call another's.
nq-x11 is known to work at least well enough for the demos. More testing
will come.
QF now uses its own configuration file (quakeforge.cfg for now) rather
than overwriting config.cfg so that people trying out QF in their normal
quake installs don't trash their config.cfg for other quake clients. If
quakeforge.cfg is present, all other config files are ignored except
that quake.rc is scanned for a startdemos command and that is executed.
Useful for avoiding a pile of wrapper functions that merely pass on
command-specific data to the actual implementation. Used to clean up the
wrappers in nq and qw cl_input.c
preparation of separating GIB into its own module. Command-related
functions will stay in util, but the buffer handling code and interpreter
will be moved out of cmd.c.
With any luck it should actually work this time. Added the getimpulse
command so that GIB scripts can check if an impulse command is pending
before sending their own. Fixed all the memory leaks I could find.
QuakeC and GIB seem to be clean except for maybe one or two sneaky leaks
I can't track down.
This allows Cmd_Return_f to decide which buffer it should return a value
to. End result: you can put blocks of code with a return statement inside
an embedded command statement. I hope nobody minded me using my
quakeforge.net account to code a bit :P
Cmd_TokenizeString since I realized the code was just pulling it apart and
putting it back together. Added Cmd_Argsu to access the unprocessed
command. Added support for else following if in such a way that
if/else if/else structures work. Added support for unary operators in
EXP and added the ! (not) operator. The ifnot command will be kept
for variety.
to GIB. Fixed a bug in dstring_replace that was causing too much data to
be copied when the incoming string was larger than what was being replaced.
Very minor reorganization in cmd.c (1 function moved around I think).
cmd.c should probably get broken up into separate files soon.
handled, meaning that execution can be paused at any time without a hitch.
Warning: This is a major change to the architecture (or lack thereof) of
GIB. Please test for bugs! Also, there are a few ugly bits of code that
need to be cleaned up, but that work for now.
This means things like echo ~{somefunc arg1 arg2} will get parsed properly
without having to enclose it in quotes. Exported the Cmd_Return function
so that anything can return values to GIB (such as quakec).
structure to help tidy the command buffer struct up a bit, fixed a few
bugs and probably created 100 more. A lot of things were changed to
allow embedded commands:
- Old buffers on the stack are left alone for Cbuf_ExecuteStack to
clean up. This is so return values can be extracted from them.
- The imperative flag has been added. An imperative buffer and all buffers
following it can not be paused with the wait command.
- The returning flag and retval dstring have been added. If a buffer
returned something, the flag will be set.
- The return command was added so there was something to use in the
substitution. Return nukes all loop buffers since they don't really count
as independent functions, sets the return value on the top buffer, and
clears it.
- Who knows what else.
now recycled, not freed. Fixed some bugs in exp.c. Ready to add embeded
functions (read: function calls with return values) and for loops.
Probably some other misc. fixes, I tend to go on debugging streaks.
Made variable substitution recursive, so ${${foo}} will be the value of
the variable whose name is contained in foo. Added setl command to
manipulate local variables. The only other place they can be used is in
variable substitution.
buffers to be linked into execution stacks and changed aliases and script
files to be run in a new stack frame. Cbuf_Execute executes the stack from
the top down, so wait commands are handled properly.
Changed Cmd_TokenizeString to accept a flag that controls the application
of filters (tags, variables, escape characters) to the tokens and modified
a few places in the source that called it. Added a secondary command
buffer that is parsed without filters for legacy command support.
Currently, it is only used for commands stuffed into the console from the
server. It is hacky, and I hope to eventually generalize the console
interface to support any number of buffers and audit the rest of the code
to recognize it. For now, the legacy buffer at least keeps escape
character parsing from destroying info strings.
console command parser. It will eventually include html-like tags for
modifying text (gold numbers, brown characters, etc) and escaped characters.
The major differences so far are that dynamic strings are now used instead
of static buffers, and single quotes can be used to enclose tokens as
well as double quotes.
api change: Cmd_Args () now takes a parameter inidcating which arg to
start at for grabbing the un-parsed command line
qw/source/sv_ccmds.c:
implement kk's tell command and user name matching (though # is used for
the wildcard and it's still case sensitive)
everything else:
adjust for the new Cmd_Args protype
