通常地，我们引用源代码的要求有：
- 字体样式与正文有明显区分，美观大方
- 可以标注代码行号
- 可以添加背景色，可以添加边框
- 可以对援引源代码进行语法高亮
那么listing宏包一定是你非常好的选择！
listing宏包支持代码上色的语言非常之多，目前所支持的语言有：
ABAP IDL Plasm ACSL inform POV Ada Java Prolog Algol JVMIS Promela Ant ksh Python Assembler Lisp R Awk Logo Reduce bash make Rexx Basic Mathematica RSL C Matlab Ruby C++ Mercury S Caml MetaPost SAS Clean Miranda Scilab Cobol Mizar sh Comal ML SHELXL csh Modula-2 Simula Delphi MuPAD SQL Eiffel NASTRAN tcl Elan Oberon-2 TeX erlang OCL VBScript Euphoria Octave Verilog Fortran Oz VHDL GCL Pascal VRML Gnuplot Perl XML Haskell PHP XSLT HTML PL/I当然，这个语言列表可能会随时间推移而逐渐庞大，如果你所援引的语言暂时不在上述之列，你仍可以自定义语法高亮的规则，不过，这便不再本文讨论之范畴。
以下给出的是使用了listing宏包的TeX代码示例，该代码可以使用LaTeX，pdfLaTeX，XeLaTeX等编译通过。
