是否有可能编写自己的“包"?对于LaTeX? [英] Is it possible to write own "packages" for LaTeX?

问题描述

作为一名程序员，我想知道是否可以为LaTeX创建自己的软件包.我需要类似著名的列表"程序包的东西，但更能满足我的需求.我正在寻找一个清单解决方案，该解决方案需要提防诸如

As a programmer, I wonder if I could create my own package for LaTeX. I need something like that famous "listings" package, but something that is much more capable for my needs. I look for a listings solution that would watch out for a comment line like

// BEGIN LISTING 3122

// END LISTING 3122

不突出显示语法，但是智能地支持制表符缩进.然后，该软件包将与文件名或路径一起使用，遍历各行，然后仅复制感兴趣的代码段.

No syntax highlighting, but intelligent support for tab indents. That package then would be used with a file name or path, walk through the lines and copy out just the snippets of interest.

我100％确信市场上绝对没有这样的东西.所以我想为LaTeX编程.如果可能的话.我不知道如何以及使用哪种编程语言/IDE.我将从哪里开始寻找?

I am 100% sure there is absolutely nothing like this on the market. So I want to program it for LaTeX. If that's possible. I have no idea how and what programming language / IDE. Where would I start looking?

推荐答案

当然可以，但这在TeX编程语言中并不简单.我现在没有时间对其进行编码，但是这里有一个算法.我建议在comp.text.tex上询问更具体的LaTeX编程建议.

This is certainly possible, but it is non-trivial in the TeX programming language. I don't have time to code it up at the moment but here's an algorithm; I suggest asking on comp.text.tex for more specific LaTeX programming advice.

• 在本地将所有特殊字符的猫码设置为其他"(\dospecials)，并开始逐行(\read)读入输入文件
对于每行
• ，请比较该行的第一个标记，但要比较多个标记(对\if或\ifx的某些迭代使用；可能有一个使它更容易使用的包，例如stringstrings或xstring)
  • 在默认状态下，扔掉输入行并阅读下一行
  • 除非它是// BEGIN LISTING，在这种情况下，请将每行保存到一个宏中(类似于\g@addto@macro)
  • 直到它是// END LISTING，显然
  • Locally set all catcodes of special chars to "other" (\dospecials) and start reading in the input file line by line (\read)
  • for each line compare the first however many tokens of the line (some iterative use of \if or \ifx; there might be a package to make this easier such as stringstrings or xstring)
    • in the default state throw away the input line and read the next
    • unless it's // BEGIN LISTING, in which case save each line into a macro (something like \g@addto@macro)
    • until it's // END LISTING, obviously

    按主题划分的TeX 是这类工作的很好的参考指南.

    TeX by Topic is a good reference guide for this sort of work.
