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.
within braces, and put support for comments back in (oops). To use math
evaluation, put a math expression inside $(). If you have spaces in your
expression, you'll need to enclose the entire thing in quotes so it doesn't
get split up into multiple tokens.
won't be processed except for escape characters, so that escaped braces
can be used within. If an uneven number of curly braces are within a
token, it will be misparsed, so escaped braces are important if you
don't want them to be considered in the parsing of the token. Ideally,
braces within quotes within braces should not need to be escaped, but this
would require a redesign of the parser to be recursive. Maybe I will do
this later.
without considering that realloc could result in dstr->str being
changed. Also made variable substitution of non-existant variables be
replaced with a null string rather than being left alone, to prevent
errors in scripts from causing weirdness as strings get passed through
the parser several times.
normal quotes and made it so executed files are always inserted into the
console buffer so that class config files in TF can use the new parser
features, even though the exec command is run in the legacy buffer
and it will get replaced with the ith argument to the alias, 0 being the
name of the alias itself. %% will get replaced by %, out of range
numbers will simply be removed, and non-numbers will be ignored.
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.
generally cleaned the parser up. If a line begins with |, it will be
stripped off by the tokenizer and no tags or escape characters will be
processed. Commands stuffed into the console from the server are prepended
with | to ensure backward compatibility. This can also be used anywhere
backward compatibility is needed, such as where info strings are stuffed
into the console, or as an alternative to using escape characters in the
entire string.
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.

but the core file does accurately show the error
the background. This is achieved by doing only a (qf)glFlush at the end of
the frame, doing the inter rendering-frame processing (ie, client frame
processing), glFinish, glXSwapBuffers, then starting the next frame. I've
changed the glFinish call in SCR_UpdateScreen to glFlush and the glFlush
call in GL_EndRendering to glFinish because there's no point in calling
glFinish followed by glFlush. Also, SwapBuffers should always be precedded
by glFinish rather than just glFlush (in Lordhavoc's experience). The
GL_EndRendering at the end of SCR_UpdateScreen got moved to the beginning.
done by setting the allkeys param to 1. when this is the case, if the menu
item function returns 0, normal processing is done, otherwise processing
stops.
