How can you show/reveal hidden characters in NetBeans? In other editors, if this feature is turned on, a space might be shown as a small centered dot, and a tab as a right arrow. (This feature is useful to see if a file uses tabs or spaces for indentation, among other things.)
推荐答案
此功能已丢失很长时间了-功能请求于1999年11月创建，并最终于2010年8月实现(NetBeans 6.10).您可以在"视图→显示不可打印的字符"中启用/禁用它.
This feature was missing for a long time—a feature request was created on November 1999 and it was finally implemented on August 2010 (NetBeans 6.10). You can enable/disable it at "View → Show Non-printable Characters".
从NetBeans 7.0.1开始，不可打印"的定义似乎包括制表符和回车符，但不包括常规空格字符:
As of NetBeans 7.0.1, the definition for "non-printable" seems to include tabs and carriage returns but not regular white space char:
NetBeans 7.1.0最终显示空格.但是，现在有了一个新的错误，即连续的制表符(或制表符和空格的组合)折叠成一个制表符:
NetBeans 7.1.0 finally displays spaces. However, now it has a new bug where consecutive tabs (or tabs & spaces combinations) collapse into one tab:
NetBeans 7.4.0修复了此问题:
NetBeans 7.4.0 fixes this:
还有两个问题:
-
文件结尾用
The end of file is represented with the same symbol as line feeds, thus making it non-obvious to determine whether the file ends with EOL.
隐藏的字符以与常规文本相同的颜色显示.
Hidden chars are displayed in the same colour as regular text.
到目前为止，这些问题尚未得到解决，但是可以通过进行缓解.编辑器空白第三方插件，
These issues have not been addressed so far but they can be sort of mitigated with the Editor Whitespace third-party plugin, which:
- 隐藏EOL和EOF标记(无论如何都没有用).
- 使用始终相同的颜色显示其他空白字符.
