Eval Lang
A pretty weird language that evaluates in a human way, made to be forgiving and looks like js.
field=Others
field='Others'
field="Others"
field = Others
field=Others;
field=9;
field > 9;
field < 9
field <= 9
field =< 9
field => 9
field >= 9
field;
field[
{ field: 'field', operator: '=', value: 'Others' },
{ field: 'field', operator: '=', value: 'Others' },
{ field: 'field', operator: '=', value: 'Others' },
{ field: 'field', operator: '=', value: 'Others' },
{ field: 'field', operator: '=', value: 'Others' },
{ field: 'field', operator: '=', value: '9' },
{ field: 'field', operator: '>', value: 9 },
{ field: 'field', operator: '<', value: 9 },
{ field: 'field', operator: '=<', value: 9 },
{ field: 'field', operator: '=<', value: 9 },
{ field: 'field', operator: '>=', value: 9 },
{ field: 'field', operator: '>=', value: 9 },
{ field: 'field', operator: '!' },
{ field: 'field', operator: '!' }
]Does it require a javascript engine to run? No, when you parse this you'll get array (per line) of dictionaries with the field name, operator & value.
The current design.
field(( )[=|>|<|>=|=>|=<|<=]( )('|")value('|"))(;)Note
This is not a programming language, it's not turing complete, and I'm not planning to make it so.
There are things missing, for my use-case this was enough.
- XOR operator (planning to use
^) - AND operator (planning to use
&) - NOT operator (planning to use
!=) - HAS operator (planning to use
~) - A standard evaluator function, that evaluates the evaluation dictionary
- Port it to Python, Java/Kotlin & Dart
I hope you'll contribute to this repo.
Do what ever you want with this, but keep in-mind I am not responsible
for any-type of damage it or it's usage/mis-use in any usecase have caused.
