降价为实现C / C ++ [英] Markdown Implementations for C/C++

问题描述

什么是降价以C或C ++？

我通过谷歌找到了这些，并且将AP preciate评论有关哪些运作良好，哪些没有（和哪些我可能已经错过了）：

• PEG-降价


• 折扣


• CPP-降价


• libsoldout （原libupskirt）

解决方案

1. PEG-降价 取决于能说会道，其他第三部分的工具。我测试过它，它工作得很好。

   优点：

   
   
   • GPL和麻省理工学院下的双重授权。
   
   
   • 使用内部正式的语法，所以容易维护和扩展。
   
   

   缺点：

   
   
   • 取决于GLib的
   
   
   • 提供C API。
   
   



2. CPP-降价，大多数C ++ code，但它是相当慢，有点臃肿。在另一方面，它是很容易理解和修改，取决于升压1.35。

   优点

   
   
   • 在升压只依赖
   
   
   • 用C ++编写，貌似不太危险
   
   
   • MIT授权。
   
   

   劣势

   
   
   • 慢（但仍快约10倍，那么Perl实现，但折扣比慢约10倍）
   
   



3. 折扣，这是code我用我的博客 http://art-blog.no-ip.info/ cppcms /博客和wiki <一个href=\"http://art-blog.no-ip.info/wikipp/en/page/main\">http://art-blog.no-ip.info/wikipp/en/page/main.它是由铁杆C程序员，相当难以mantainable（即使开发商activly保持它）。

   写

   优点

   
   
   • 极快
   
   
   • 用纯C（无第三部分依赖）。
   
   
   • 积极维护
   
   
   • 的宽容3 clause BSD许可证
   
   

   劣势

   
   
   • 几乎不可能维持（甚至我可以删除/添加一些素质特征分析）。
   
   
   • <罢工>的唯一文件API，所以我应该调整的code，使其与一般的缓冲合作。
   
   
   • <击>下的是与GPL不兼容的4 clause BSD许可证授权。如果你想不使用它作为您的GPL-ED软件的一部分，它是有问题的。
   
   

为什么我知道他们这么多？

我开发 CppCMS 的，所以我需要一个好的降价到HTML转换器。当我拿起一（折扣），这是唯一的解决方案。从那时起，我需要它取代因授权问题。尽管如此，我还是挺喜欢它，因为它是最快的降价方案。

P.S：如果你想C ++包装的折扣，采取<一看href=\"http://cppcms.svn.sourceforge.net/viewvc/cppcms/cms/trunk/cxxmarkdown/\">http://cppcms.svn.sourceforge.net/viewvc/cppcms/cms/trunk/cxxmarkdown/,它不是最新版本，但它已经被调整。

编辑：我刚刚访问折扣网站，我发现，它已经增加了一个非文件API为好。因此，现在是真正的图书馆。

编辑2：如果您找到更好的实现或写在FOSS许可证自己，让我知道;）

修改3：为cloose评论，折扣改变了许可证3条第BSD

What is the best implementation of Markdown for C or C++?

I found these via Google, and would appreciate comments about which ones work well and which ones don't (and which ones I may have missed):

• peg-markdown
• Discount
• Cpp-Markdown
• libsoldout (formerly libupskirt)

解决方案

1. peg-markdown depends on GLib and other 3rd part tools. I've tested it, it works quite well.

   Advantages:

   • Dual-licensed under GPL and MIT.
   • Uses internally formal grammar, so easy to maintain and extend.

   Disadvantages:

   • Depends on GLib
   • Provides C API.

2. Cpp-Markdown, Most C++ code but it is quite slow and little bit bloated. On the other hand it is quite easy to understand and modify, Depends on boost-1.35.

   Advantages

   • Depends only on boost
   • Written in C++, looks like less dangerous
   • Licensed under MIT.

   Disadvantages

   • Slow (it is still about 10 times faster then Perl implementation, but about 10 times slower than Discount)

3. Discount, This is the code I use for my blog http://art-blog.no-ip.info/cppcms/blog and wiki http://art-blog.no-ip.info/wikipp/en/page/main. It is written by hardcore C programmer and quite hardly mantainable (even the developer activly maintains it).

   Advantages

   • Extremely fast
   • Written in pure C (no 3rd part dependencies).
   • Actively maintained
   • Has permissive 3 clause BSD license

   Disadvantages

   • Almost impossible to maintain (even I could remove/add some fatures).
   • Has only FILE API, so I should tweak the code to make it work with general buffer.
   • Licensed under 4 clause BSD license that is incompatible with GPL. It is problematic if you want to use it not as part of your GPL-ed software.

Why do I know them so much?

I'm developing CppCMS, so I need a good markdown to HTML convertor. When I picked one (Discount), it was the only solution. Since then I've needed to replace it due to licensing issues. That said, I still quite like it because it is the fastest Markdown solution.

P.S.: If you want C++ wrapper for Discount, take a look on http://cppcms.svn.sourceforge.net/viewvc/cppcms/cms/trunk/cxxmarkdown/, It is not the latest version, but it is already tweaked.

EDIT: I have just visited Discount site and I had found that it had added a non-FILE API as well. So now it is real library.

EDIT 2: If you find better implementation or write your own under FOSS license, let me know ;)

EDIT 3: as cloose commented, discount had changed the license to 3 clause BSD.
