### Limitations
|
||||||
|
|
||||||
|
This highlighter makes no attempt to determine if a word is in command position.
|
||||||
|
Hence if you run the command `cat foo` and you happen to have a directory named
|
||||||
|
`cat` in the current directory, then the highlighter will highlight `cat`
|
||||||
|
according to `ZSH_HIGHLIGHT_FILE_TYPES[di]` and not
|
||||||
|
`ZSH_HIGHLIGHT_STYLES[command]` (assuming you load the `files` highlighter after
|
||||||
|
the `main` one). Likewise with aliases, reserved words, etc.
