What is wrong with my .ctags file?

Question

I am a ctags newbie, coding in PHP. I have found this ctags file online: ``` -R --exclude=.svn --tag-relative=yes --PHP-kinds=+cfpd --regex-PHP=/abstract\s+class\s+([^ ]+)/\1/c/ --regex-PHP=/interface\s+([^ ]+)/\1/c/ --regex-PHP=/(public\s+|static\s+|protected\s+|private\s+)\$([^ =]+)/\2/p/ --regex-PHP=/const\s+([^ =]+)/\1/d/ --regex-PHP=/final\s+(public\s+|static\s+|abstract\s+|protected\s+|private\s+)function\s+\&?\s*([^ (]+)/\2/f/ ``` However, I am getting this error: ``` $ ctags ctags: Warning: Unsupported parameter 'p' for --PHP-kinds option ``` From experimentation I see that the `p` needs to be defined, and in fact it is defined on the seventh line of the file. So why is the error being thrown? EDIT: The ctags file came from here, which was linked from this terrific article. Here is the output of my configuration: ``` $ ctags --version ctags: Warning: Unsupported parameter 'p' for --PHP-kinds option Exuberant Ctags 5.6, Copyright (C) 1996-2004 Darren Hiebert Compiled: Jan 6 200…

Accepted Answer

The 'p' kind is not defined for PHP by default.

```
--regex-PHP=/(public\s+|static\s+|protected\s+|private\s+)\$([^     =]+)/\2/p/
```

is defining a 'p' kind for PHP in your case. If you move

```
--PHP-kinds=+cfpd 
```

after this, it will not give you an error.

Note: Here is my version info for ctags:

```
$ ctags --version
