Core Plan

[jcpwfloi]

1. Code Highlighting.
   The Interface should be highlight [code_name] and should output code_name.php
2. Code Automatic Highlighting
   This part should be written in javascript.
3. Code Compiling
   We should write a safety-check program to make sure the program does no harm to our server, and running in the sandbox is optional.
   The interface should be:
   fake_compile xxx.cpp
   fake_compile xxx.pas
   fake_compile xxx.java
   fake_compile xxx.cc
   fake_compile xxx.c
   etc.
4. Code History Version
   The SAM algorithm should be used to check the change of the code, and we must design an algorithm to choose a optimized solution among a range of codediffs.
   There'll be two programs that provide interfaces.
   1. Merge [code_historical] [xxx.patch]
   2. Generate [code_historical_version] [code_current_version]
      and it should generate a readable patch list.

some other declarations and interfaces will be given next time.
this is the initial developing plan.

On code safety checking:
It is dangerous if someone run literal data (static array/string) as code (via function pointer). Checking is necessary.
Or.. full sandbox-like virtualization backend? Can be a long-term plan XD.

so the string check is of course crucial, continuous unicode char or hexadecimal should be prohibited. the feature will be added in safety-check.
