lsmath by Fallout ver 0.3.2

HOWTO

available step.rc commands:
MathReadOnlyRCVars [bool] allows you to use evars within equations
evars are read-only because the module would need to know where the var is if it can be changed.
MathDebug [bool] brings all kinds of messageboxes
very minimal debugging for your math equations
MathWarnings [bool]warnings from your scripts
MathErrors [bool]errors from your scripts x/0, etc.

this dll provides 3 bangs:
!mathfile filename
!mathequation equationargs
!mathsave
It is meant to work with mzscript.dll to extend its capabilities (but you can do other things like assign equations to hotkeys if you desire, or even hotspots!)

!mathfile filename

!mathequation equationargs

!mathsave

example:
$configdir$varfile.rc
---------------------
width 51
height 11
style 2

$configdir$script.rc
--------------------
*script bang !setwidthheight
    *script exec !mathequation width=3*(5+6*style)
    *script exec !mathequation height = 3 + 4 * style
*script ~bang

*script bang !increasestyle
    *script exec !mathfile $configdir$varfile.rc
    *script exec !mathequation style += 1
    *script exec !setwidthheight
    *script exec !mathsave
*script ~bang

*script bang !decreasestyle
    *script exec !mathfile $configdir$varfile.rc
    *script exec !mathequation style -= 1
    *script exec !setwidthheight
    *script exec !mathsave
*script ~bang


notes about $configdir$varfile.rc (or whatever file(s) you are using to store variables)

• it can be included
• anything that doesn't begin with a letter or an underscore is not read as a variable
• lines that begin with the following are not parsed: IF ELSE ENDIF
• spaces and tabs are ignored
• variables are stopped from being read when a line is reached that begins with ;;;
• do not put any string variables above ;;; because they will cause unpredictable results

more things to know

• integers are truncated, not rounded (remember it's C style)
• decimals should work for any operater that is defined for them
• variables are case sensitive
• do not attempt to edit the file at any point between a call of !mathfile and !mathsave because your edit will be lost
• this is by no means a finished product but more of a public beta
• the code is ugly, esp for the file usage, I plan on making it better for the next version. This is more or less because I consider the written code to be an algorithm that happens to compile
• if you think you have found a bug tell me about it (and fix it if you wish)

File list

To come

• code rewrite to make it easier to read, more portable, and better style (it gets the job done but I don't like how it is written)
• bugfixes (when they are found)
• anything else depends on request

changes

• ver 0.3.2
  • fixed reading negative numbers(just forgot to put those 2 lines in)
  • fixed variables being removed from the file (thanks ed)
  • added MathReadOnlyRCVars
  • removed exe from file, stopped working on it so it is the same code as before
• ver 0.3.1
  • minor bugfix (module didn't load)
• ver 0.3
  • one bug known about but I have no desire to fix it, you can omit closing parenthesis and equation will not set error to 1, (go ahead and look at it in the exe for better understanding of how this works)
  • fixed #/0 - now returns 0 and sets error to 1
  • fixed #%0 - now returns 0 and sets error to 1
  • fixed some integer operations could return doubles when they weren't suppossed to
  • oops, assignment now goes right to left, like it is suppossed to, code on wrong line
  • added conditional operator
  • fixed a bug that makes + and - unary if they are after )
• ver 0.2
  • stable
  • needs a very thourough bug check, and is why I am releasing it (I cannot do it on my own)
  • implementation of features from .1 is complete
  • project contains 2 binary files, a dll and an exe, the exe is a command line processer to aid in finding bugs. Open it and type help for more info.
• ver 0.1
  • added operators ^ & ~ ! < > | = << >> != <= >= == && || ~= %= ^= &= *= /= |= -= += <<= >>=
  • added file input and output
  • added support for variables
• ver 0
  • start of project
  • operators supported + - % * / ( )
  • not very useful b/c no = allowed
