fafb014bbe Oops. Fixed a stupid bug that broke having more than one embedded command
in a token.

cb79de3584 Completely redid the way embedded functions are subroutines in general are
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.

49deaf2661 that wasn't meant to get checked in. it came from an aborted change to
how commands get register.

c3da90fce0 You can now assign to local variables with var = value. You can also
index into variables in either substitution (i.e. $bob[25]) or assignment
(i.e. bob[25] = 'q') When using assignment into an index of a var, the
current character is removed and replace with the new value.  That means
that if the new value is longer than one character, the string will grow.
A feature that may be done in the future is indexing between two values
to get a substring, ie bob[25..30] = newstr.

503dab1aee The tokenizer will now not break tokens appart within quotes or braces.
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).

93c9f96416 Added embedded commands with ~{} and the return command, created a token
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.

676bf39d9d Beautified GIB, improved looping and backtraces slightly. Old buffers are
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.

executed files to crash the server.

e1b61d2116 Changed how looping works, fixed echo to work with taniwha's Cmd_Args
changes, added the != operator for math evaluation, added break command
to break out of loops early, added ifnot command, and who knows what else.

388ff7b597 Some bug fixes and memory leak fixes. Local variables break randomly,
probably due to my misuse of hash tables.  Anyone have any ideas?

d5fad096c0 Added local variables and replaced %-substitution with local variables.
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.

added error backtraces.

46cc4ac9dd Fixed some bugs and generalized the command buffer interface. Allowed for
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.

f4180e7ad8 Added math evaluation, the ability for commands to span multiple lines
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.

aa00b7742c Changed the token finder to be recursive, added if and while commands, and
allow tokens within braces to continue across newlines.

e9ca911e34 Added the ability to use curly braces to enclose tokens. Tokens in braces
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.

2a3e1869ac Bug fixes! Fixed escape character detection, use of str = dstr->str
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.

0a90ddc51f Fixed an error in extract line that caused escaped quotes to be parsed as
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

669ca72e4f Added a bonus feature: %i evaluation in aliases. Just put %i in an alias
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.

7241d69036 Fixes to echo, correct use of cmd_source and src_command, and change nq to

8d124f9c2b Implemented variable substitution and did various cleanups to the parser.
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.

f78ec56975 Added escape characters, the <i> tag to ignore tags enclosed within it, and
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.

557846b220 This is the first commit to the newcmd branch, which is a mostly-rewritten
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.

8be15a16e6 heh, turned out that didn't hurt overkill as much as I thought, but this
gives it a tiny boost (and will help more in the more alias heavy mods).

008b59b777 The beginnings of an f_* reply system have been added. f_version works
like normal, f_skins reports the average percent fullbright for all loaded
skins, and f_skins skinname reports the fullbright percent for a signle
skin.  cl_freply controls the time in seconds before another query can be
made.  Set it to 0 to disable them.  More queries will be added later.
The table for accessing special characters from the console has been
tweaked a bit.  Expect it to get tweaked more in the future.

05f35f9cd4 This adds the ability to access special characters in console commands by proceeding certain characters with $. See libs/util/cmd.c for the conversion table. Preceeding a character by # will shift it up or down by 128, which basically is useful for accessing the brown letters and numbers. All special characters were removed from Team_ParseSay, and variable substitution now takes the form of ${var} to prevent conflicts with special character substitution. Special character access is controlled by cmd_highchars, which defaults to off. 2001-10-27 04:34:53 +00:00
