E-Kréta is an awful Hungarian electronic school administration system

Magyar leírás

IMPORTANT!

When upgrading from v0.5.21, credentials have to be recreated. It's necessary, as from v0.5.22, encoding is used for storing passwords.

1. You have to manually find and delete them. A user called Alice would find credentials under:
   • linux: /home/alice/.config/rsfilc/credentials.toml
   • windows: C:\Users\Alice\AppData\Roaming\rsfilc\credentials.toml
   • mac: /Users/Alice/Library/Application Support/rsfilc/credentials.toml
2. recreate all users with rsfilc user --create

Installation

• Rust

• cargo install --locked rsfilc

  for latest, beta builds: cargo install --locked --git "https://codeberg.org/jark/rsfilc"

Dependencies

optional, recommended

• lynx: for enjoyable (html) message previews
• w3m: for enjoyable (html) message previews

Shell completions:

Bash

Add this to the end of your config file (usually ~/.bashrc):

eval "$(rsfilc completions bash)"

Zsh

Add this to the end of your config file (usually ~/.zshrc):

eval "$(rsfilc completions zsh)"

For completions to work, the above line must be added after compcompletions is called. You may have to rebuild your completions cache by running rm ~/.zcompdump*; compcompletions.

Fish

Add this to the end of your config file (usually ~/.config/fish/config.fish):

rsfilc completions fish | source

PowerShell

Add this to the end of your config file (find it by running echo $profile in PowerShell):

Invoke-Expression (& { (rsfilc completions powershell | Out-String) })

Elvish

Add this to the end of your config file (usually ~/.elvish/rc.elv):

eval (rsfilc completions elvish | slurp)

Note RsFilc only supports elvish v0.18.0 and above.
