Question

我试图通过引入几倍的平均数,使晚期变得可行,但我对确定完全任意终止环境的新指挥感到不安。

This works:
ewcommand{cv}{ensuremath{egin{smallmatrix}}} ewcommand{ecv}{ensuremath{end{smallmatrix}}} ewcommand{e}{egin{enumerate}} ewcommand{ee}{end{enumerate}}

This does not work:
ewcommand{al}{egin{align*}} ewcommand{eal}{end{align*}}
ewcommand{verbass}[1]{egin{verbatim} #1 end {verbatim}}

具体而言,我认为最终价值只是被忽视吗?

当我尝试使用<条码>。我犯了一个错误:! 文件在扫描使用@xverbatim时结束。



显然,我可以在必要时在所有地点使用egin-{foo}......终端{foo},但这确实应当奏效!

Answer 1

egin{verbatim} work。简略扼要。

egin{verbatim} is expanded to verbatim.
Then verbatim sets category code of each characters to 11. Now all chars is letters.
Then verbatim sets font, parindent and calls @xverbatim.
利用以下trick计达到逐字记录的结尾:
```
def@xverbatim#1end{#1end}
```
然后,结束工作。

How ewcommand{verbass}[1]{egin{verbatim} #1 end {verbatim}} work.

First of all verbass{Halp} reads its argument.
#1 --> Halp
verbass expands to egin{verbatim} Halp end {verbatim}. Important: backslash of end has category 0 rather than 11. Moreover { and } have categories 1 and 2 rather than 11.
Then egin{verbatim} expands to varbatim. varbatim changes all categories and font. But (important) the category of backslash (in end) remains equal to 0.
Then verbatim calls @xverbatim.
试图利用以下trick计来抓你的论点:
```
def@xverbatim#1end{#1end}
```
but it is impossible because of @xverbatim tries to catch end where all letters (,e,n,d) have the category 11. But in fact there are four letters with other category code: with category 0 and e,n,d with category 11.
@xverbatim is trying and trying to find end where backslash () has category 11 but.... File ended while scanning use of @xverbatim

Answer 3

我远非专业方案家,但迅速解决的办法可以是:


ewcommand{myverbatim}[1]{egin{tt} detokenize{#1} end{tt} \ }

产出不是很微不足道,因为分界线被忽略。如果有此愿望,可以重复指挥线(?)。
