    I used this app but I get this bug

  • Fix potential bug with os not in english

    Fix potential bug with os not in english

    Hi, After some tests with your tool, I discovered a little problem for some setups.

    To detect SSID, it's using nmcli -t -f active,ssid dev wifi | egrep '^yes' | cut -d\: -f2. The problem is that nmcli -t -f active,ssid dev wifi output depends of language. In english it will return SSID yes/no but for example in french it return SSID oui/non.

    To fix that I'm forcing the language using LANG env variable.

    Cannot read SSID password if there's a space between the SSID's name

    If I run sudo wifi-password I get

    ERROR: Could not find password

    This is because my AP's name has a space inside (e.g: John DoeWifi)

    If I create a new AP and name it JohnDoeWifi, I successfully get the result

    password123

    The program doesn't take into consideration that there may be an SSID with space inside the name. Only SSIDs with no space are read.

  • Linux fixes

    Linux fixes

    This PR should bring it back to being able to work with any linux install using NetworkManager, with the added bonus of not relying on wireless-tools. This should resolve #17 and #11

    However this program will still be unable to function on a linux install that does not use NetworkManager, such as wicd or connman, or on the Raspberry Pi. The most likely scenario for supporting those is writing special cases for each, though I did not go through the effort in this commit.

    Maybe its also worth merging into its own branch to get some more testing instead of merging directly to master?

  • parameter --image doesn't work

    parameter --image doesn't work

    version: 1.0.2

    IS: calling wifi-password with -i or --image shows the password in the terminal.

    SHOULD: show the qr code as an image

    SUGGESTION: let the user specify a name and/or a path including the file extension(.jpeg, .png, etc.). If no extension is give or the extension is invalid, fall back to a default extension.

    Unable to find the password

    Hi!

    I appreciate the work you put in this, but sadly it doesn't work for me.

    I'm using Kubuntu 22.04 and the WiFi is a hidden network. If I run the command nmcli -s -g 802-11-wireless-security.psk connection show '{ssid}' manually, it outputs the password though. Do I have to set up something first?

    Thanks in advance! Greetings, Noah Streller
