Ever wanted a maybe safe way to resolve or take in a boolean expression from the user or a configuration.
The input of: S$employee_name==BoB||(F$salary<<20.5||F$salary>=100) Is resolved to handle check if employees name equals BoB or the salary is in the range
| Input | Resolved comparison |
|---|---|
| == | equals |
| != | not equal |
| >> | greater than |
| << | less than |
| >= | greater than or equal |
| <= | less than or equal |
| Input | Resolved type |
|---|---|
| S | string |
| I | integer |
| F | float |
| Input | Resolved type |
|---|---|
| || | or |
| && | and |
| ( | open grouping |
| ) | close grouping |
| Keyword | Resolved value |
|---|---|
| EMPTY_STRING |
A best effort was done to restrict possible malicious input and if it is found then a ValueError is raised that needs to be caught.
