Introduction

In this tutorial we learn how to install libixion on Fedora 34.

What is `libixion`

Ixion is a general purpose formula parser & interpreter that can calculate multiple named targets, or “cells”. The goal of this project is to create a library for calculating the results of formula expressions stored in multiple named targets, or “cells”. The cells can be referenced from each other, and the library takes care of resolving their dependencies automatically upon calculation. The caller can run the calculation routine either in a single-threaded mode, or a multi-threaded mode. The library also supports re-calculations where the contents of one or more cells have been modified since the last calculation, and a partial calculation of only the affected cells need to be calculated. Supported features - Each calculation session is defined in a plain text file, which is parsed and interpreted by the Ixion parser. - Fully threaded calculation. - Name resolution using A1-style references. - Support 2D cell references and named expressions. - Support range references. - Dependency tracking during both full calculation and partial re-calculation. - Inline strings. - Volatile functions. The framework for volatile functions is implemented. We just need to implement more functions. libixion 0.16.1 4.fc34 x86_64 275 k libixion-0.16.1-4.fc34.src.rpm fedora A general purpose formula parser & interpreter library https MPLv2.0 Ixion is a general purpose formula parser & interpreter that can calculate multiple named targets, or “cells”.

We can use yum or dnf to install libixion on Fedora 34. In this tutorial we discuss both methods but you only need to choose one of method to install libixion.

Install libixion on Fedora 34 Using dnf

Update yum database with dnf using the following command.

sudo dnf makecache --refresh

The output should look something like this:

Fedora 34 - x86_64                               20 kB/s | 6.6 kB     00:00
Fedora 34 openh264 (From Cisco) - x86_64        1.4 kB/s | 989  B     00:00
Fedora Modular 34 - x86_64                       68 kB/s | 6.5 kB     00:00
Fedora 34 - x86_64 - Updates                    3.5 kB/s | 6.2 kB     00:01
Fedora Modular 34 - x86_64 - Updates             17 kB/s | 5.9 kB     00:00
Metadata cache created.

After updating yum database, We can install libixion using dnf by running the following command:

sudo dnf -y install libixion

Install libixion on Fedora 34 Using yum

Update yum database with yum using the following command.

sudo yum makecache --refresh

The output should look something like this:

Fedora 34 - x86_64                               20 kB/s | 6.6 kB     00:00

Metadata cache created.

After updating yum database, We can install libixion using yum by running the following command:

sudo yum -y install libixion

How To Uninstall libixion on Fedora 34

To uninstall only the libixion package we can use the following command:

sudo dnf remove libixion
