| Aug 27, 2019 at 10:51 | comment | added | Bart van Ingen Schenau | @ShahlinIbrahim: Yes, that is exactly the job of a parser. | |
| Aug 27, 2019 at 10:47 | comment | added | Shahlin Ibrahim | @BartvanIngenSchenau Is it possible to build an abstract syntax tree from tokens? | |
| Aug 27, 2019 at 10:41 | comment | added | Bart van Ingen Schenau | @ShahlinIbrahim: You should research the topic of parsers. Your way of validation was most likely too simplistic, because the language you described should pose no problem at all for a parser. | |
| Aug 27, 2019 at 7:35 | comment | added | Shahlin Ibrahim | @BartvanIngenSchenau I tried to check if the tokens are valid by looping through each one. But the possibilities are too many. There can be nested expressions, strings, functions, variables, etc. at any location. I guess maybe my way of validating was wrong | |

| Aug 27, 2019 at 7:00 | comment | added | Bart van Ingen Schenau | @ShahlinIbrahim, the next step is to create a parser that can tell from a set of tokens if they form a valid construct in your language and what that construct means. | |

| Aug 27, 2019 at 6:50 | comment | added | Shahlin Ibrahim | @Kain0_0 Thank you for the recommendation, will give it a read. As mentioned above, I am using Doctrine Lexer for lexing, it's the next steps that I don't know of | |
| Aug 27, 2019 at 6:14 | comment | added | Kain0_0 | There are many lexing/grammar packages out there. You simply need to search for them. I found reading Crafting Interpreters to be quite helpful in general. | |
