Installation

Install rust and cargo

Change the directory path to an absolute path so calender can be run from everywhere for these 3 files:

• The date storage file

  Cicada/src/main.rs

  Line 13 in f1811ff

  const DATE_FILE_PATH: &str = "./src/dates/date.file";

• The file containing the password used for de-/encrypting the date storage file

  Cicada/src/main.rs

  Line 15 in f1811ff

  const PWD_LOC: &str = "./src/dates/.pwd";

• The file containing the salt for the password

  Cicada/src/main.rs

  Line 14 in f1811ff

  const SALT_LOC: &str = "./src/dates/.salt";

• The file where the ids of already alerted appointmens are stored

  Cicada/src/main.rs

  Line 20 in aabc47c

  const ALERT_LOC: &str = "./src/dates/.alerted";

  Run cargo build --release to create a binary of the program.

If you want a faster version go back to this ab2af0cb14e9f06685caa38b1500de6ce6059b2f commit. The file ecryption makes it slower.
