6.腾讯office

腾讯推出了tim，目前只提供文字处理（word）、电子表格（excel）两方面的服务，虽然在整合腾讯系其他产品方面（例如腾讯地图、腾讯问卷等）、在检索能力方面（Evernote印象笔记可以全文检索）仍有待提升。

不过一个感觉是，QQ在面对自家兄弟微信的竞争之后，终于找到了自己的位置和发力点。

11.百度文档

百度也许曾经试图追赶一下谷歌，只是步伐好像虚浮、绵软，百度Doc（在线word）、百度脑图（在线思维导图）的研发给人的感觉也是心不在焉。

百度网盘推出了在线编辑文件功能，也是整合在线office的一个努力。

12 Pandoc支持多种格式文本之间的转换

About pandoc

If you need to convert files from one markup format into another, pandoc is your swiss-army knife. Pandoc can convert between the following formats:

(← = conversion from; → = conversion to; ↔︎ = conversion from and to)

Pandoc understands a number of useful markdown syntax extensions, including document metadata (title, author, date); footnotes; tables; definition lists; superscript and subscript; strikeout; enhanced ordered lists (start number and numbering style are significant); running example lists; delimited code blocks with syntax highlighting; smart quotes, dashes, and ellipses; markdown inside HTML blocks; and inline LaTeX. If strict markdown compatibility is desired, all of these extensions can be turned off.

LaTeX math (and even macros) can be used in markdown documents. Several different methods of rendering math in HTML are provided, including MathJax and translation to MathML. LaTeX math is converted (as needed by the output format) to unicode, native Word equation objects, MathML, or roff eqn.

Pandoc includes a powerful system for automatic citations and bibliographies. This means that you can write a citation like

[see @doe99, pp. 33-35; also @smith04, ch. 1]

and pandoc will convert it into a properly formatted citation using any of hundreds of CSL styles (including footnote styles, numerical styles, and author-date styles), and add a properly formatted bibliography at the end of the document. The bibliographic data may be in BibTeX, BibLaTeX, CSL JSON, or CSL YAML format. Citations work in every output format.

There are many ways to customize pandoc to fit your needs, including a template system and a powerful system for writing filters.

Pandoc includes a Haskell library and a standalone command-line program. The library includes separate modules for each input and output format, so adding a new input or output format just requires adding a new module.
