# zsh-manpage-completion-generator



Automatically generate zsh completions from man page using fish shell completion files.  

This program is inspired from [nevesnunes/sh-manpage-completions](https://github.com/nevesnunes/sh-manpage-completions).  

But it supports more completion files and is much simply implemented, faster and easier to use, written in Go.



## Requirements



This program depends on fish shell's manpage converter, [create_manpage_completions.py](https://github.com/fish-shell/fish-shell/blob/master/share/tools/create_manpage_completions.py).  

So you must first install fish shell, See below for installation instructions.



https://github.com/fish-shell/fish-shell



If you do not want to install fish, you can also manually place and run the conversion python script as an example below.



```

# download script

$ sudo wget --backups=1 -P /usr/local/bin/ https://raw.githubusercontent.com/fish-shell/fish-shell/master/share/tools/{create_manpage_completions,deroff}.py

$ sudo chmod a+x /usr/local/bin/{create_manpage_completions,deroff}.py



# create arbitrary fish completion folder

$ mkdir ~/fish_generated_completions



# generate fish completions from manpage

$ create_manpage_completions.py --manpath --cleanup-in ~/fish_generated_completions -d ~/fish_generated_completions --progress



# and then specify -src option to convert

$ zsh-manpage-completion-generator -src ~/fish_generated_completions

```



## Installation



**From binaries:**



Download the binary from [GitHub Releases](https://github.com/umlx5h/zsh-manpage-completion-generator/releases/latest) and place it in your `$PATH`.



Install the latest binary to `/usr/local/bin`:



```bash

curl -L "https://github.com/umlx5h/zsh-manpage-completion-generator/releases/latest/download/zsh-manpage-completion-generator_$(uname -s)_$(uname -m).tar.gz" | tar xz

chmod a+x ./zsh-manpage-completion-generator

sudo mv ./zsh-manpage-completion-generator /usr/local/bin/zsh-manpage-completion-generator

```



**Homebrew:**



```bash

brew install umlx5h/tap/zsh-manpage-completion-generator

```



**AUR (Arch User Repository):**



with any AUR helpers

```

yay -S zsh-manpage-completion-generator-bin

paru -S zsh-manpage-completion-generator-bin

```



**Go install:**



```bash

go install github.com/umlx5h/zsh-manpage-completion-generator@latest

```



## Usage



You must first generate fish competion files.  

It generates completion files, usually under folder `$XDG_DATA_HOME/.local/share/fish/generated_completions`



```console

$ fish -c 'fish_update_completions'

Parsing man pages and writing completions to /home/dummy/.local/share/fish/generated_completions/

```



Then generate zsh completions from fish completions folder.  

By default, it is generated in folder `$XDG_DATA_HOME/.local/share/zsh/generated_man_completions`



```console

$ zsh-manpage-completion-generator

Converting fish completions: /home/dummy/.local/share/fish/generated_completions -> /home/dummy/.local/share/zsh/generated_man_completions

Completed. converted: 2579/2581, skipped: 142

```



Then add completions folder to your `fpath` in `.zshrc`.  

(It is recommended to place them at the end of the `fpath`, so that human-generated completions such as [zsh-users/zsh-completions](https://github.com/zsh-users/zsh-completions) will be preferred.)



```

fpath=(

   $fpath

   $HOME/.local/share/zsh/generated_man_completions

)

compinit # This is not necessary if it is called after this.

```



You may have to force rebuild zcompdump



```console

$ rm -f "${ZDOTDIR-~}/.zcompdump" && compinit

```



It is recommended that `compinit` be called only once because of the startup time.  

You can check the number of calls to `compinit` by using `zprof`.



Note that `fpath` must be added before `compinit`.  

If you are using any zsh framework, check where it is adding `fpath` and calling `compinit`.



## Option



The following command line options are supported.



You can change the path to the fish and zsh completions by specifying `-dst` and `-src`.  

The `-clean` option can be specified to remove zsh completion folder before generating them.  

This is useful for removing completions that are no longer needed.  

(Note that the entire `-dst` folder will be deleted.)



```console

$ zsh-manpage-completion-generator -h

Usage of zsh-manpage-completion-generator:

  -clean

        CAUTION: remove destination folder before converting

  -dst string

        zsh generated_completions destination folder (default "/home/dummy/.local/share/zsh/generated_man_completions")

  -src string

        fish generated_completions src folder (default "/home/dummy/.local/share/fish/generated_completions")

  -verbose

        verbose log

  -version

        show version

```



## Caveat



- Some invalid options may be generated, but there is nothing that can be done about this, as this is also the case with fish.
