I'm having this following error message:

/usr/bin/lua5.2: /home/arafat/.config/conky/weather/weather.lua:60: attempt to index global 'cache' (a nil value) stack traceback: /home/arafat/.config/conky/weather/weather.lua:60: in function 'makecache' /home/arafat/.config/conky/weather/weather.lua:70: in main chunk [C]: in ?

Can you help me please?

Wind direction in weather.lua:80 is decoded wrong. Right solution
`
degrees_to_direction = function (d)
val = math.floor(d/22.5 + 0.5)
directions = {
[0] = "N", [1] = "NNE", [2] = "NE", [3] = "ENE",

return directions[val % 16]

@alo0oz - the problem is the path. You can either CD to the path where the script is located or you can edit weather.lua and add:

wdir = os.getenv("HOME").."/path/to/directory/"

Near the top of the script where /path/to/directory/ is your directory.
Then concatenate that variable in the 3 places in the script:
so...

if file_exists(wdir.."weather.json") then
cache = io.open(wdir.."weather.json","r")

and..
cache = io.open(wdir.."weather.json", "w+")

I used your code as a starting point for my own script. I just refactored some of it to lose the global variables. If anyone needs it, here it is.

I've updated the script to latest working version. The api stopped giving wind direction so that is removed and min/max temp were added in. I need to clean it up a bit more. Maybe in the future I can also add in 3 day forecast.

@FSchliephacke thanks so much for sharing your script! :D

I modified you code slightly to use a JSON cache file in a consistent location:
$HOME/.config/conky

This makes my home directory maintenance much easier. I also cleaned up the output to suite my personal conky configuration.

Here is the updated moonphase.lua:

#!/usr/bin/lua
https = require("ssl.https")
json = require("json")

-- To use edit variables below for your timezone and location then add the next line to your conky config, uncommented
-- ${alignc}${execpi 3600 ~/.config/conky/moonphase.lua}

-- Change to your timezone offset
--- EST -5, EDT -4
tz = "-4"

-- Change to the lattitude and longitude you want to use
lat = "XX.43"

  ["Waning Crescent"] = "🌘"
}
cachefile = os.getenv("HOME")..("/.config/conky/moonphase.json")

file_exists = function (name)
    f=io.open(name,"r")
    if f~=nil then
        f:close()
        return true
    else
        return false
    end
end

if file_exists(cachefile) then
    cache = io.open(cachefile,"r")
    data = json.decode(cache:read())
    cache:close()
    timepassed = os.difftime(curtime, data.timestamp)
else
    timepassed = 6000
end
makecache = function (s)
    cache = io.open(cachefile, "w+")
    s.timestamp = curtime
    save = json.encode(s)
    cache:write(save)
    cache:close()
end

if timepassed < 3600 then
    response = data
else
    mooninfo = https.request(api_url)
    if mooninfo then
        response = json.decode(mooninfo)
        makecache(response)

You can just add the ${alignc} conky directive in your conky.conf:
${font Fira Mono:size=14}${alignc}${execpi 3600 ~/.config/conky/cal.lua}${font}

I did a big update for this script. There is a new api and it uses latitude and longitude instead of city ID. It now gives forcaste information along with the current weather.

Wind direction in weather.lua:80 is decoded wrong. Right solution
`
degrees_to_direction = function (d)
val = math.floor(d/22.5 + 0.5)
directions = {
[0] = "N", [1] = "NNE", [2] = "NE", [3] = "ENE",
[4] = "E", [5] = "ESE", [6] = "SE", [7] = "SSE",
[8] = "S", [9] = "SSW", [10] = "SW", [11] = "WSW",
[12] = "W", [13] = "WNW", [14] = "NW", [15] = "NNW"
}
return directions[val % 16]
end

`

Thanks, I added to the script. I can try to update to use local vars as well. Sorry I am a bit slow. Maybe I should move all this to it's own repository at some point.

${font Fira Mono:size=14}${alignc}${execpi 3600 ~/.config/conky/cal.lua}${font}

Bumping ~5 months old post, cause these days I spent lot of useless, but very very interesting hours - top fun time, to fit these scripts to my taste and positioning of calendar was one of challenges (don't take me wrong: I like to have candy desktop and this kind of modding is very interesting for me - I enjoy it, but I have to say it is useless cause it is :) πŸ‘― πŸ‘― :) ).

1st thing: Thanks to @meskarune for scripts and concept!!!

2nd thing: @jnyilas: unfortunately, this couldn't be accomplished with Conky alignment, cause putting any ${offset xx}, ${alignc}, ${alignr}, etc. in front or middle of ${font Fira Mono:size=14}${execpi 3600 ~/.config/conky/cal.lua}${font} will move/align only first line, i.e. December 2020, like this:

I am not developer. Usually I am able to edit finished code and fit it to my needs, but this was my first time with Lua and hadn't success to figure out could this be aligned inside cal.lua file. So i used workaround/cheat/hack whatever and piped conky exec line for cal.lua to sed, adding spaces in front to every line:

${font Ubuntu Mono:size=14:style=bold}${execpi 3600 ~/.config/conky/cal.lua | sed 's/^/ /'}${font}

(there are lot of SPACEs between two slashes above / / , but it seems that github code tag is displaying all of them as one SPACE)

Anyway, this is my final desktop and I am happy:

image

I would paste my edit of weather.lua here, cause I made 7 days forecast and will be glad to give my contribution here - @meskarune: please be free to implement it in your script if you want. @ALL: Please note that you will need either to revert back icons to unicode icons in weather.lua or you will need icon font I made for this, where I used someone else icons (or you will need to make that font). Reason why I'm not providing everything right now is because I'm lazy :) . I used lot of someone else work for this and if I want to publish my work, I need to credit all these people properly. It will require some more work and hours and I cannot know will this be interesting for even one person at all. I can promise, if someone wish all resources, I will immediately publish this somewhere with all proper credits and share link here - please just let me know (I subscribed to this topic :) ).

At the end, once again, I am not developer and I believe that this probably can be done better and more elegant, but it doing the job for me and I am ok with that.

Hello.
I had a hard time at first to show something, but after a boot it worked.

My suggestion is to create a step-by-step for beginning users. It was not so intuitive for me to have to create an account and a API KEY at api.openweathermap.org and replace it in the wheater.lua file, as well as inform my lat/long values. In any case, this solution has enormous potential. Congratulations!

In my case, for Ubuntu 20.04, as I never developed on the moon (I thought it was pretty cool) I had to run the commands:

sudo apt install lua5.3
sudo apt install lua-socket
sudo apt-install lua-json
chmod 755 ~/.config /conky /*.lua
