3. Configuration option for doing instant selection in search mode
3. Configuration option for doing instant selection in search mode
## Installation
```
sh -c "$(curl -fsSL https://raw.githubusercontent.com/psprint/zsh-navigation-tools/master/doc/install.sh)"
```
To update run the command again.
`ZNT` will be installed at `~/.config/znt/zsh-navigation-tools`, config files will be copied to `~/.config/znt`. `.zshrc`
will be updated with only `8` lines of code, which will be added at the bottom.
After installing and reloading shell give `ZNT` a quick try with `Ctrl-R` – this keyboard shortcut will open `n-history`.
## Installation With [Zplugin](https://github.com/psprint/zplugin)
Add `zplugin load psprint/zsh-navigation-tools` to `.zshrc`. The config files will be in `~/.config/znt`.
## Installation With Zgen
Add `zgen load psprint/zsh-navigation-tools` to `.zshrc` and issue a `zgen reset` (this assumes that there is a proper `zgen save` construct in `.zshrc`).
The config files will be available in `~/.config/znt`.
## Installation With Antigen
Add `antigen bundle psprint/zsh-navigation-tools` to `.zshrc`. There also
should be `antigen apply`. The config files will be in `~/.config/znt`.
## Single File Manual Installation
Running script `doc/generate_single_file` will create single-file version of `ZNT`.
It can be sourced from `.zshrc`. Don't forget about configuration files as described
above.
## Manual Installation
After extracting `ZNT` to `{some-directory}` add following two lines
Create aliases to avoid typing of the minus sign "-":
```zsh
alias naliases=n-aliases ncd=n-cd nenv=n-env nfunctions=n-functions nhistory=n-history
alias nkill=n-kill noptions=n-options npanelize=n-panelize nhelp=n-help
```
Don't forget to copy [configuration files](https://github.com/psprint/zsh-navigation-tools/tree/master/.config/znt). They should go to `~/.config/znt`. Moreover, `n-cd` works together with option `AUTO_PUSHD` and you should have:
```zsh
setopt AUTO_PUSHD
```
in `.zshrc` (also recommend `PUSHD_IGNORE_DUPS`). Without the option `n-cd`
will just work as incremental searcher of directory bookmarks.
## History Widget
To have `n-history` as the incremental searcher bound to `Ctrl-R` copy `znt-*`
files into the `*/site-functions` dir (unless you do single file install) and
add:
```zsh
autoload znt-history-widget
zle -N znt-history-widget
bindkey "^R" znt-history-widget
```
to `.zshrc`. This is done automatically when using the installer, zgen, antigen
or single file install. Two other widgets exist, `znt-cd-widget` and
`znt-kill-widget`, they too can be assigned to key combinations (`autoload` is done
in `.zshrc` so no need of it):
```zsh
zle -N znt-cd-widget
bindkey "^B" znt-cd-widget
zle -N znt-kill-widget
bindkey "^Y" znt-kill-widget
```

## A tip
Zsh plugins may look scary, as they seem to have some "architecture". In fact, what a plugin really is, is that:
1. It has its directory added to `fpath`
2. It has any first `*.plugin.zsh` file sourced
That's it. When one contributes to Oh-My-Zsh or creates a plugin for any plugin manager, he only needs to account for this.
The same with doing any non-typical Zsh Navigation Tools installation.
