Use latex to typeset multiple-choice test paper

Food Guide ： Use python The language implements latex Pure text Automated choreography

---

One 、 Requirements describe

Work reason , You need to make a sheet containing 100 Multichannel selection Choose the test paper .
For beautiful typesetting , I got a job LaTeX Multiple choice question template ,
It's too troublesome to manually input each line , Then we found the corresponding Automation module

---

The most embarrassing thing happened , I found that the editor has its own replacement function ,
And support regular expressions

Two 、 Solution

1. Content processing

(1) Text answer digging

Copy several pages of the questionnaire txt In the text file , In order to dig out these correct answers , Replace with regular expressions directly

2. Typesetting processing

(1) The template is local miktex The compiler in

In order to achieve this step , There are three main points to pay attention to .

1. install miktex Choose to install... For all users
   ( Make sure the software starts , to update , The old version has some deadly bug)
2. Use xelatex compile
   ( In order to compile some macro packages normally )
3. Use ctex In the macro package ctexart Document class
   ( Don't display Chinese correctly , Make sure it is installed ctex Macro package , Installation can refer to The lack of lastpage Macro package processing method )

(2) Source code analysis of templates

３. Text and latex Interaction

Think of each topic as a basic unit , Function encapsulation of this basic unit
And then call 100 The second function can realize the writing of the whole manuscript .

3、 ... and 、 Encountered bug

1. LaTeX Problems arise

take LaTeX Multiple choice question template Copied to the TeXworks In the process , The following error has been reported .

Duplicate installation , Remember to choose for all users

The use of wildcards

By reference This blog The method is as follows ：

I solved this problem perfectly

Environmental problems

[ resolved ] LaTeX Medium enumerate The environment appears overfull box The situation of

Four 、 Exotic curiosity-a solution looking

##（ One ） Copied to the WPS Handle (word It's the same , Support genuine domestic )

##（ Two ） Use word Replacement sequence of
Use wildcards to replace
1. Question number replacement （ Replace two digits first , Replace one digit ： As for why not replace it all at once , Because I won't ）

First look at the content of wildcards ：^# For any number , Don't forget the back “、”, Otherwise, it may match the number in the stem

^#^#、

I want to change the sequence directly to latex Medium item command , because \item The command can automatically generate a sequence , Here is latex Source code , In contrast , It's easy to understand , Replacement target

But the sad thing is that direct replacement will report an error ,

So I improved

Here is my fifth replacement ,} must Because if you import latex in ,D You will find that there is no alternative slogan after choosing , Do you want to add one by one manually , Later, I found that I could change the serial number , Just manually Delete the first , to The last one is added with brackets That's it .^p Line break , It's OK to , Or add a few more as you need . It's for my latex The source code is more readable .（latex Source code inside , Segmentation equals newline , It should be because the compiler has to eat an empty line to know the end of a line ）^092 I won't say why ,~ It is used as a space , stay latex in , Otherwise \item There is no gap with the following Chinese , The command cannot be recognized

^#^#、
}^p^092item~

##（ 3、 ... and ） The answer is hollowed out
Use it directly

（  ）

Make a selection parenthesis
Replace with

~^092underline{
    ~~~~~~~~}

##（ Four ）A The option is replaced by the command
This order determines that I line up the multiple-choice questions , Or two lines , Or four elements .
Because most of the options are short , For the purpose of reducing manual modification , Select single line command ,
Insert picture description here

Don't compile when you finish modifying , Definitely , There should be some options only ABC No, D, I refer to the single line function written to compare dishes , You can't adapt to the three options .

^#^#、
}^p^092item~

##（ 5、 ... and ）B,CD Replace the selection with the corresponding brackets }{
^$ Represents any letter

This is the most embarrassing thing
