|
|
+## 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
|
|
|
+to `~/.zshrc`:
|
|
|
+
|
|
|
+```zsh
|
|
|
+fpath+=( {some-directory} )
|
|
|
+source "{some-directory}/zsh-navigation-tools.plugin.zsh"
|
|
|
+```
|
|
|
+
|
|
|
+As you can see, no plugin manager is needed to use the `*.plugin.zsh`
|
|
|
+file. The above two lines of code are all that almost **all** plugin
|
|
|
+managers do. In fact, what's actually needed is only:
|
|
|
+
|
|
|
+```zsh
|
|
|
+source "{some-directory}/zsh-navigation-tools.plugin.zsh"
|
|
|
+```
|
|
|
+
|
|
|
+because `ZNT` detects if it is used by **any** plugin manager and can
|
|
|
+handle `$fpath` update by itself.
|
|
|
+
|
|
|
+## Truly Manual Installation
|
|
|
+Copy (or link) all `n-*` and `znt-*` files to **/usr/share/zsh/site-functions/**
|
|
|
+(or **/usr/local/share/zsh/site-functions/**, check with `echo $fpath[1]`) and then add:
|
|
|
+
|
|
|
+ autoload n-list n-cd n-env n-kill n-panelize n-options n-aliases n-functions n-history n-help
|
|
|
+
|
|
|
+to `~/.zshrc`.
|
|
|
+
|
|
|
+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.

+# Fixing tmux, screen and linux vt
|
|
|
+
|
|
|
+If `TERM=screen-256color` (often a case for `tmux` and `screen` sessions) then
|
|
|
+`ncv` terminfo capability will have `2`nd bit set. This in general means that
|
|
|
+underline won't work. To fix this by creating your own `ncv=0`-equipped
|
|
|
+terminfo file, run:
|
|
|
+
|
|
|
+```zsh
|
|
|
+{ infocmp -x screen-256color; printf '\t%s\n' 'ncv@,'; } > /tmp/t && tic -x /tmp/t
|
|
|
+```
|
|
|
+
|
|
|
+A file will be created in directory `~/.terminfo` and will be automatically
|
|
|
+used, `tmux` and `screen` will work. Similar is for Linux virtual terminal:
|
|
|
+
|
|
|
+```zsh
|
|
|
+{ infocmp -x linux; printf '\t%s\n' 'ncv@,'; } > /tmp/t && tic -x /tmp/t
|
|
|
+```
|
|
|
+
|
|
|
+It will not display underline properly, but will instead highlight by a color,
|
|
|
+which is quite nice. The same will not work for FreeBSD's vt, `ZNT` will detect
|
|
|
+if that vt is used and will revert to highlighting elements via `reverse` mode.
