WordPress套件《APH Prism Syntax Highlighter》讓程式碼高亮度語法顯示

有一些人使用 WordPress 來當程式筆記,在不像傳統編輯器一樣,在 WordPress 文章中展現程式碼並不會有高亮度語法。而《APH Prism Syntax Highlighter》 是一個 WordPress 的套件,主要功能是讓 WordPress 中,可以高亮度顯示,讓你的讀者能更快看懂你的程式碼唷!

 

 

Step 1.
去 WordPress 後台搜尋「APH Prism Syntax Highlighter」後來安裝,安裝完成後,在後台按下【設定】→【Prism Highlighter】,在「Choose Language】中選擇要支援的語言,如果你所要展現的程式碼沒有在這些語言,可以按下【Add Language】

 

Step 2.
《APH Prism Syntax Highlighter》支援相當多語言,如 Java、Objective-C、Swift、CSS、HTML…,等都支援,可以說是應有盡有。

Step 3.
在「Theme」則是程式碼展現給讀者看的顏色配置及背景,可以依自己的需求來選擇。

 

Step 4.
設定完後,如果要插入程式碼,如果要在文章內插入程式碼,只要按下《APH Prism Syntax Highlighter》按鈕。

 

Step 5.
接著,輸入你的程式碼。

 

Step 6.
在 Other Options 則是可以做進階設定,如要不要顯示行號等,有需要的朋友再請自行設定。

 

Step 7.
而底下是插入程式碼後的結果,由於是在編輯器的預覽,所以不會有高亮度顯示,但在發表後,就會有高亮度顯示的程式碼囉!

 

 

而底下是展示範例,是以 Java 的程式碼來做展示
