In this section, you will find how to build formulas on Ritchie.

This functionality is no longer available from **Ritchie's 2.5.0 version**. From now on, a formula build is automatically made on your CLI: a local repo file will be created as soon as you implement the formula to host it.
If you're using a previous version just follow the instructions of this section.

After **creating a formula**, if you want to edit the code of the formula, it's necessary to **build** these changes to test the command with the new implementation.

To do so, just run the command:** **

rit build formula

You must inform:

The

**directory's path**where the formula is located.The

In case you want to update the formula's code in running time, you can use the **flag “--watch”** as shown in the command below:

rit build formula --watch
