Haskell的完全功能的CSV解析器？ [英] Fully featured CSV parser for Haskell?

问题描述

任何人都可以建议使用以下选项解析CSV文件：

• 设置单元格/字段分隔符


• 设置记录结束/行终止符


• 为字段设置引号字符


• 支持UTF-8字符串


• 将内存中CSV结构写回文件的能力

我尝试了Text.CSV，简单和缺乏上述大部分功能。
是否有一些更高级的CSV解析模块，或者我必须从头开始编写，即使用Text.ParserCombinators？

解决方案

p>我不能推荐一个现成的，打包的Haskell的CSV解析器，但我记得这本书 由

相关的 /book.realworldhaskell.org/read/using-parsec.htmlrel =noreferrer>第16章：使用Parsec 可在线获取;请检查标题为扩展示例：完整CSV解析器的部分。

Can anybody recommend a way to parse CSV files with options to:

• set cells/fields separator
• set end of record/row terminator
• set quote-character for fields
• support of UTF-8 strings
• ability to write in-memory CSV structure back to a file

I did try Text.CSV but it's very simple and lacks most of the above features. Is there some more advanced CSV parsing module or do I have to write it "from scratch" i.e. using Text.ParserCombinators? I do not intend to reinvent a wheel.

Take care.

解决方案

I can't recommend a ready-to-go, packaged-up CSV parser for Haskell, but I remember that the book Real-World Haskell by Bryan O'Sullivan et al. contains a chapter on Parsec, which the authors demonstrate by creating a CSV parser.

The relevant chapter 16: Using Parsec is available online; check the section titled Extended Example: Full CSV Parser.
