如何从 Haskell 中的列表编写 LaTeX 文件？
How do I write a LaTeX file from a list in Haskell?
好的，我有这样的东西：
[Just [["Value1"],["","",""]],Just [["Value2"],["","","","","","","","","","","","","","","","","","","","","","","","","","","Value3",""]],Just [["Value4","",""]],Just [["Value5"],["","",""]],Just [["Value6"],["","",""]],Just []]
我需要将所有这些值写入 LaTeX 文件，忽略空字符串（可能成对，每对一行）。
我该怎么做？
谢谢
编辑：我的文件应该是这样的：
Value1 Value2
Value3 Value4
Value5 Value6
- 将您的输入简化为
[String] 形式 ["Value1", "Value2", "Value3", "Value4", "Value5", "Value6"]。函数 catMaybes、concat、filter 和 null 可能会有帮助。
- 将您的价值观分组。根据您的需要，您可能喜欢手写或使用
split 包中的 chunksOf。
- 与
unwords合并对；将成对集合与 unlines. 组合
- 使用
writeFile 写入您的文件。
除非特别注明，所有这些函数都在标准库中。
