如何从Haskell中的列表中编写LaTeX文件？

好的，我有一些东西看起来像这样：

[Just [["Value1"],["","",""]],Just [["Value2"],["","","","","","","","","","","","","","","","","","","","","","","","","","","Value3",""]],Just [["Value4","",""]],Just [["Value5"],["","",""]],Just [["Value6"],["","",""]],Just []]

 Value1 Value2
 Value3 Value4
 Value5 Value6

我需要将所有这些值写入一个LaTeX文件，忽略空字符串（可能成对，每对一行）

我该怎么做呢

谢谢

编辑：我的文件应如下所示：

[Just [["Value1"],["","",""]],Just [["Value2"],["","","","","","","","","","","","","","","","","","","","","","","","","","","Value3",""]],Just [["Value4","",""]],Just [["Value5"],["","",""]],Just [["Value6"],["","",""]],Just []]

 Value1 Value2
 Value3 Value4
 Value5 Value6

将您的输入简化为

[“Value1”、“Value2”、“Value3”、“Value4”、“Value5”、“Value6”]

格式的

[字符串]

。函数

catMaybes

、

concat

、

filter

和

null

可能会有所帮助

将您的值分组成对。根据您的需要，您可以手工编写或使用

split

软件包

与

UNWORD

组合成对；将成对的集合与

未线形组合起来

使用

writeFile

写入文件

---

除非另有说明，否则所有这些函数都在标准库中。

我不确定是否理解您的要求。如果您为您的示例添加了预期的输出latex源文件，可能会有所帮助？我的文件应该是这样的：一些字符串，一些其他值，一些值更多值嘿，出现了一个值！或者更好的说法是：Value1 Value2 Value3 Value4 Value5 value6我刚刚编辑了这个问题，现在应该更有意义了。感谢您的输入有不平衡的列表分隔符（

[

和

]

）和字符串分隔符（

“

），并且包含“Value4”的列表不是

可能是[[string]]

与其他部分一样。请确保输入有效，并澄清与所需转换相关的部分。很抱歉，这是我的错误，我刚刚修复了它。感谢您指出
