    [![hackmd-github-sync-badge](https://hackmd.io/5kfxJMHQSde3xqu_z9gGkw/badge)](https://hackmd.io/5kfxJMHQSde3xqu_z9gGkw) ## MarkDown 語法 ![](https://i.imgur.com/hLed4Je.png) - John Gruber 在 2004 年創造了 Markdown 語言,目的是希望大家使用「易於閱讀、易於撰寫的純文字格式,並選擇性的轉換成有效的XHTML(或HTML)」。 - 其中最重要的設計是可讀性,也就是說這個語言應該要能直接在字面上的被閱讀,而不用被一些格式化指令標記(像是RTF與HTML)。 因此,它是現行電子郵件標記格式的慣例。參閱[Markdown 語法說明](https://markdown.tw/)、[Markdown -wiki](https://zh.wikipedia.org/wiki/Markdown) - MarkDown語法無所不在,常用到的地方包含: - 編寫GitHub的`Readme.md`檔 - 編寫Jupyter Notebook的文字描述 - 技術部落格[Medium](https://medium.com/) - iThome的技術文章 - 筆記軟體Evernote - Line的訊息也可以 - 還有筆者最愛的[HackMD](https://hackmd.io/) ## LaTex 語法 - 官方網站[the LaTeX product](https://www.latex-project.org/) - $LaTeX是寫數學算式的一種排版系統,也是可以方便在web、論文等上面呈現的書寫方式,不然在word等文字編輯器一直上標下標很惱人。 - 由於LaTeX是透過語法來排版的,任何想得到的東西,像是演算法公式、樂譜、棋譜、化學結構式、電路圖及物理學中的費曼圖等等都可以先定義規則,然後再以簡單的語法排版出來。而那些規則也往往早有人寫出對應,所以使用者只需要弄懂他的語法就可以了,詳細可參閱[LaTeX - wiki](https://zh.wikipedia.org/zh-tw/LaTeX)。 - 然後Github、[HackMD](https://hackmd.io/)等支援Markdown語法的編輯器幾乎都可以直接執行基本的LeTeX操作,非常方便! ## 小結 - 筆者在寫技術文章時,最常使用的編輯環境其實是[HackMD](https://hackmd.io/),而現代網頁編輯器都會在上方有快捷列,推坑HackMD是因為編輯環境中,只要拖曳圖片,就會幫你上傳到免費圖床[imgur](https://imgur.com/)並且提供網址,`![](https://i.imgur.com/縮圖網址)`,複製貼到iThome或寫repo的README更方便啦!礙於主題,如有興趣請參閱[HackMD功能介紹](https://hackmd.io/features-tw),另有簡報模式、書本模式、GutHub同步功能等,並新增Chrome擴充功能。 - 今天就先介紹文件編輯語法後結束,我們下篇見!
