cannot get ranger_zlua.py working

[m040601]

Hi, thanks for all the work on z.lua. Nice to see the repository still active and the tool cared for. I love it and have been using all these years

I am trying to use it with ranger.

I read what the ranger wiki says, https://github.com/ranger/ranger. And what z.lua says, /usr/share/z.lua/README.md,

copy the `ranger_zlua.py` file to `~/.config/ranger/plugins/`.

Question 1 I am not 100% sure. Should I also chmod +x it ? I did it anyway

Question 2

# $RANGER_LUA and $RANGER_ZLUA variables are deprecated, do not use them.
ZLUA_LUAEXE = os.environ.get('RANGER_LUA') or os.environ.get('ZLUA_LUAEXE')
ZLUA_SCRIPT = os.environ.get('RANGER_ZLUA') or os.environ.get('ZLUA_SCRIPT')

No matter what I tried I cannot have it working.

ranger_zlua: Could not find z.lua, please make sure $ZLUA_SCRIPT is set to absolute path of z.lua.
Error while loading plugin 'ranger_zlua'

I have a standard Archlinux installation. No hacks, not customizations. I have on my bashrc

eval "$(lua /usr/share/z.lua/z.lua  --init bash enhanced once )"

On my shell

$ echo $ZLUA_LUAEXE

/usr/bin/lua

$ echo $ZLUA_SCRIPT

/usr/share/z.lua/z.lua

Are correctly displayed.

The only way I found was to hardcode and change in ranger_zlua.py both

ZLUA_LUAEXE = "/usr/bin/lua"
ZLUA_SCRIPT = "/usr/share/z.lua/z.lua"

Then it works.

I am not a developer. Not very proficient with git. The only possibly related stuff I found were these commits from 2 years ago,

f347eaf 2Y Ilya Grigoriev  o Slight stylistic edits to `ranger_zlua.py`
e11d2e2 2Y Ilya Grigoriev  o Fixes and docs for the ranger plugin
9dc5875 4Y Sami Kankaristo o Fix `z -I` in ranger_zlua.py
1e0e352 5Y skywind3000     I add ranger plugin for z.lua

-PATH_LUA = os.environ.get('RANGER_LUA') or os.environ.get('ZLUA_LUAEXE')
-PATH_ZLUA = os.environ.get('RANGER_ZLUA') or os.environ.get('ZLUA_SCRIPT')
+ZLUA_LUAEXE = os.environ.get('RANGER_LUA') or os.environ.get('ZLUA_LUAEXE')
+ZLUA_SCRIPT = os.environ.get('RANGER_ZLUA') or os.environ.get('ZLUA_SCRIPT')

Could you confirm me that "ranger_lua.py" is up to date and properly working on your own system ?

By the way. You have

......
# class z(ranger.api.commands.Command):
    def execute (self):
        import sys, os, time
        .....

When youu press "?" for help, and then "c" for commands in ranger, a help page shows up for that :command.

You could add something for example,

# class z(ranger.api.commands.Command):
    """
    :z <foo>
    :z -i <foo>

    You can also put `alias zb z -b` into `~/.config/ranger/rc.conf`.
    Bla bla bla ... does this and that ....
    Bla bla bla ... does this and that ....
    Example usage ... foo ... bar
    """
    def execute (self):
        import sys, os, time
        ....

Thanks in advance.

for my occasion of ohmyzsh, it's because i has use ohmyzsh with plugin https://github.com/skywind3000/z.lua/blob/master/z.lua.plugin.zsh, which set ZLUA_SCRIPT="${0:A:h}/z.lua" https://github.com/skywind3000/z.lua/blob/f80e22498cf23cce7fb0f240900360f96193a5b6/z.lua.plugin.zsh#L3

since env varibles only take effect on current shell when set without export https://stackoverflow.com/questions/19070615/python-os-getenv-and-os-environ-dont-see-environment-variables-of-my-bash-she

Method 1: So just replace this expression in ~/.oh-my-zsh/custom/plugins/z.lua/z.lua.plugin.zsh to export ZLUA_SCRIPT="${0:A:h}/z.lua"

then everything is going to be all right.

Method 2 (Recommanded): If you doesn‘t use ohmyzsh， just add this to your bashrc(or zshrc) file manually. export ZLUA_SCRIPT=<your_zlua_place>/z.lua" or use export RANGER_ZLUA="/path/to/z.lua" https://github.com/skywind3000/z.lua/wiki/FAQ#how-to-integrate-zlua-to-ranger-

Additionally:

1.How does ranger find z command?

Inside a plugin file of ~/.config/ranger/plugins/, if you define a class that inherits from ranger.api.commands.Command, ranger will automatically register it as a :command.

2. ranger z has not deal with no arguments situation，so won‘t show cd history
