ccvt

ccvt is a cURRENCY cONvERtER that converts values from one currency to another. It's available both as a CLI and GUI program.

Running dependencies

• a computer,
• curl (for fetching the latest exchange rates [/optional/]),
• jq (same as above),
• any UNIX-like OS.

Building dependencies

• glibc (not based enough to use musl yet),
• Xlib (yeah, yeah, I know…),
• Nuklear (very based indeed).

Installation

Clone the repo, cd into its directory, compile and copy to /usr/local/bin/ and you're good to go!

If you're in a terminal emulator, run:

git clone https://git.mirkodi.eu/mirk0dex/ccvt # clone the repository
cd ccvt                                        # cd into its dir
chmod +x ./install.sh                          # make install.sh executable
./install.sh # this MUST be run in a terminal  # run install.sh

Building manually

Just use the Makefile, after installing the required dependencies.

make

Usage

CLI

ccvt <value to convert> <INITIAL CURRENCY> <FINAL CURRENCY>

UPPERCASE three-letter ISO 4217 currency identifiers must be given in place of <FINAL CURRENCY> or <INITIAL CURRENCY>.

To list all available currencies' identifiers, run ccvt with no arguments.

GUI

ccvt also offers a simple GUI, built using Nuklear. You can access it by looking for "cURRENCY cONvERtER" in your application menu. Alternatively, you can open a terminal window and use the command ccvt-gui.

This kind of interface has some cons to it: command line interfaces are generally quicker and more straight-forward.

If you use the "Search" function, please note that it is case-sensitive, and you must write in ALL CAPS.

Fetching new exchange rates

ccvt gets its exchange rates from a text file stored in $HOME/.local/share/ccvt/eRates.txt. This file is managed by a script called update-eRates.sh.

It uses https://api.exchangerate.host/latest, so be aware that running this script will ping this website. (The script is ran automatically when you install the program with install.sh!).

Every once in a while, if you're fine with that, be sure to run the above-mentioned script to make sure currency conversions are correct.

If you use the graphical interface, you can use the "Update exch. r.s" button to do so.
