# Completion

Loads and configures <kbd>TAB</kbd> completion and provides additional
completions from the [zsh-completions][1] project.

This module must be loaded **after** the *utility* module.

## Options

- `COMPLETE_IN_WORD` complete from both ends of a word.
- `ALWAYS_TO_END` move cursor to the end of a completed word.
- `PATH_DIRS` perform path search even on command names with slashes.
- `AUTO_MENU` show completion menu on a successive <kbd>TAB</kbd> press.
- `AUTO_LIST` automatically list choices on ambiguous completion.
- `AUTO_PARAM_SLASH` if completed parameter is a directory, add a trailing
  slash (`/`).
- `EXTENDED_GLOB` needed for file modification glob modifiers with *compinit*.
- `MENU_COMPLETE` do not autoselect the first completion entry.
- `FLOW_CONTROL` disable start/stop characters in shell editor.

## Settings

### Ignore */etc/hosts* Entries

To ignore certain entries from static */etc/hosts* for host completion, add the
following lines in *~/.zpreztorc* with the IP addresses of the hosts as they
appear in */etc/hosts*. Both IP address and the corresponding hostname will be
ignored during host completion. However, some of the entries ignored from
*/etc/hosts* still might appear during completion because of their presence in
*ssh* configuration or history).

```sh
zstyle ':prezto:module:completion:*:hosts' etc-host-ignores \
  '0.0.0.0' '127.0.0.1'
```

## Contributors

its rules and regulations. This module will be synchronized against it.
