排版源代码(Funnelweb)

排版源代码(Funnelweb)

正在使用 Funnelweb 文学编程工具,生成 Tex 输出。

在我的某些代码中,我需要在 C 源代码中插入 ASCII 代码 25。

就生成 C 代码而言,这工作正常,但是当我在 .tex 文件上运行 Latex 时,我得到:

! Text line contains an invalid character.
l.1573
...
^^Y

.tex 文件的相关部分是:

\fwbtx[
...
^Y
...
]

(在 Emacs 中; ^Y 是一个字符,而不是两个)

“fwbtx”宏定义为:

\def\fwbtx[{%
\begingroup%
\def\par{\leavevmode\endgraf}%
\catcode`\`=\active%
\obeylines%
\def\do##1{\catcode`##1=12 }\dospecials%
\obeyspaces
\parskip=0pt%
\tt%
\fwverbatimgobble}

\def\fwverbatimgobble#1]fwetx={#1\endgroup}

我相信,这应该转义所有非 ASCII 字符,这样 Tex 就不会抱怨。

有人能解释一下出了什么问题吗?

有没有一些简单的解决方法?用其他东西替换“fwbtx”宏?

任何帮助均感激不尽。

答案1

\fwbeginmacro您可以简单地改变和的定义\fwendmacro来使其成为^^Y被忽略的字符。

\def\fwbeginmacro{\begingroup\fwparskipoff\bigskip\catcode`\^^Y=9 }
\def\fwendmacro{\fwparskipon\par\endgroup}

您还可以添加新命令

\def\fwignorexxv{\catcode`\^^Y=9}

并在 之后的代码开头使用此宏\fwbeginmacro

如果它不应该被忽略而是显示,您可以使用类似如下的方法:

\tolerance=10000
\parindent=0pt
\def\fwparskipon{\parskip=\medskipamount}
\def\fwparskipoff{\parskip=0pt}
\fwparskipon
\raggedbottom
\font\fwfontnote=cmr7
\font\fwfontnorm=cmr10
\font\fwfontnorma=cmr10 scaled \magstep1
\font\fwfontnormb=cmr10 scaled \magstep2
\font\fwfontbold=cmbx10
\font\fwfontbolda=cmbx10 scaled \magstep1
\font\fwfontboldb=cmbx10 scaled \magstep2
\font\fwfontboldc=cmbx10 scaled \magstep3
\font\fwfontboldd=cmbx10 scaled \magstep4

显示 ^Y

但请注意:这是纯 TeX 和 LaTeX 代码的非常丑陋的混合!
