Question

我需要找到

sessionOpen(0, (int *)(&SessionId));

并替换如下，

sessionOpen(
\#if USE_MULTIPLE_DB
              0,
\#endif
 (int *)(&SessionId));

如何使用正则表达式搜索和替换方法实现这一点????

Answer 1

替换sessionOpen$(0), \(int \*$$&SessionId$\);

sessionOpen(\n#if USE_MULTIPLE_DB $1, #endif\n(int *)(&SessionId))

（我假设您要捕获零0）

Make sure everything is dos2unix converted if touched by something which converts it the other way. In eclipse you can select File -> Convert line delimiters to ...

WARNING: Don't mess with file encoding unless you know what you'er doing!
In eclipse these other settings are relevant:

 Right-click on Project -> Properties
    Resource -> Text File Encoding
      Might be best to leave this (Inherited from container Cp1252 for windows)

    Resource -> New Text File Line Delimiter
      Change to "unix"
 Windows -> Preferences
    General -> Editors -> Text Editors
      Select "Insert spaces for tabs"
    General -> Content types -> Text -> Tcl Content Type

Set default enccoding (leave it alone is probably best policy!)
