[Edit Recipe] App crashes when running edit command with valid input

[nus-pe-bot]

Description

App crashes when running the edit r command with valid input. In this case, I tried to change the recipe's first step to add 1/4 tblspoon of water and it crashed. Considering that it is common for recipes to have figures like 1/4, the app would likely crash frequently when the user runs the edit r command, hence the High severity given.

Steps to Reproduce

1. Run the app
2. Add the following recipe by running add r/scramble egg t/1 s/buy ingredients t/2 s/wash ingredients s/bake ingredients i/egg,2,pc
3. Edit the recipe's first step by running edit r/scramble egg s/1,add 1/4 tblspoon of water
4. The app will crash

Actual Output

When performing step 3 as mentioned above, the app will crash.

Expected Output

The app should not crash and the recipe's first step should be successfully edited.

Team's Response

We accept that it is a bug where special characters are not handled.

However, (a) we believe that it is a feature flaw and not a functionality flaw because

• The feature of taking into account special characters is not implemented in our current version, but works as expected if "normal" inputs without special characters are used.

(b) Severity should be medium, because

• program is still perfectly usable if users use 0.25 instead of 1/4 to demonstrate a step. The meaning is exactly the same.
• it is a rare case as most users will not use slashes in their steps, hence, we did not include the functionality
