javascript - replace callback function with matches -


& lt; विकी & gt; यह पृष्ठ & lt; / wiki & gt; से & lt; A href = 'wiki / this_page' & gt; यह पृष्ठ & lt; / a & gt;
कॉलबैक फ़ंक्शन का उपयोग कर: 

  text = text.replace (/ & lt; विकी & gt; (। +?) & Lt; \ / wiki & gt; / g, फ़ंक्शन (मैच) {वापसी "& lt; a href = 'wiki /" + match.replace (/ / g,' _ ') + "' & gt;" + मैच + " & Lt; / a & gt; ";});

परिणाम यह है कि टैग & lt; विकी & gt; संरक्षित है (पूर्ण मैच) - & lt; a href = 'wiki / & lt; विकी & gt; this_page & lt; / विकी & gt; 'gt; & lt; विकी & gt; यह पृष्ठ & lt; / wiki & gt; & lt; / a & gt;

क्या मैचों [0] मिलना है, मेल [1] के रूप में PHP के preg_replace_callback () ?

मैचों पैरामीटर के रूप में लेता है।

उदाहरण के लिए: 

  text = text.replace (/ & lt; विकी & gt; (। +?) & Lt; \ / wiki & gt; / g, फ़ंक्शन (मैच, सामग्री, ऑफ़सेट, S) {return "& lt; a href = 'wiki /" + content.replace (/ / g,' _ ') + "' & gt;" + + सामग्री + "& lt; / a & gt;";});

(दूसरा पैरामीटर पहला कैप्चर समूह है)

Eclipse CDT variable colors in editor -

I hope this is a good question to ask here. This programming is related, so I thought it would be better than the superuser, so I am using the CDT C ++ Eclipse plugin. I know how the editor changes colors for some things But is there a way to do that all the variables are different colors? For example in KDEValue, it sets the local variables and square variables in different colors and bold square squares. Can I copy it to CDT? Eclips provides some level of color customization for text editor syntax You can see it on the following: There are many elements, including the Window> Preferences> C / C ++> Editor> Syntax color code that can be changed, assembly, Comments, Preprocessor and Doxian Under the code, it is possible to change the color of some variable types, such as global variables, local variable announcements, local variable references, and parameter variables. But I do not think the code is capable of changing the color of each variable declared....
