正则表达式找到静态（非最终）变量 [英] Regex to find static (non final) variables

问题描述

我正在尝试在Eclipse（Java）工作区中进行搜索，以查找非最终的静态变量的所有实例。

I am trying to do a search in my Eclipse (Java) workspace to find all instances of static variables that are not final.

我尝试了各种正则表达式但是他们不要导致任何匹配。有人可以建议一个正则表达式匹配包含 static 并且不包含 final 的所有行，而不是以<$结尾c $ c> {？

I tried various regexes but they do not result in any matches. Can someone suggest a regex that will match all lines containing static and not containing final, and not ending in a {?

关于不以 {结尾的最后一部分将消除静态方法。

The last part about not ending with a { will eliminate static methods.

例如：

public class FlagOffendingStatics {
  private static String shouldBeFlagged = "not ok";
  private static final String ok = "this is fine";
  public static void methodsAreOK() {

  }
}

推荐答案

此模式有效：

[^(final)] static [^(final)][^(\})]*$

这是一个测试：

$ cat test.txt
private int x = "3";
private static x = "3";
private final static String x = "3";
private static final String x = "3";
private static String x = "3";
public static void main(String args[]) {
        blah;
}

$ grep "[^(final)] static [^(final)][^(\})]*$" test.txt
private static x = "3";
private static String x = "3";

（我意识到私有静态x =3; 是无效的语法，但模式仍然正常。）

(I realize that private static x = "3"; isn't valid syntax, but the pattern still holds ok.)

该模式解释了 final 可以在 static 之前或之后出现 [^（final）] static [^（final）] 。模式的其余部分 [^（\}）] * $ ，旨在防止任何 {个字符出现在该行的其余部分。

The pattern accounts for the fact that final can appear before or after static with [^(final)] static [^(final)]. The rest of the pattern, [^(\})]*$, is meant to prevent any { characters from appearing in the remainder of the line.

如果有人喜欢这样编写方法语句，则此模式不起作用：

This pattern will not work however if anyone likes to write their method statements like this:

private static void blah()
{
     //hi!
}
