Globals # TO-DO: GET RID OF GLOBAL STATE Yep. You seem to already understand this one. Having a reset betrays a place in your design that would be well-suited to an object that can be thrown away and re-constructed, which is usually a more useful model than existing state that can be reset. Moving on. Docstrings Rather than # parse_resp is the main function ...

Your speed-up claim: avoid loading the whole file at once, instead parsing a file line by line, which seems to be 2x as fast according to testing seems highly unlikely, and I would like to see proof of this. A compiled-and-tuned built-in JSON parser that operates on an in-memory buffer is nearly certain to outperform a non-compiled, non-built-in, line-by-...

If you have a regular pattern that describes what you want to do with a string, using a regular expression (regex) is usually a good idea. In addition to using re.split, as shown in another answer by @python_user, you can also use re.findall, which has the advantage that you don't have to manually deal with the opening and closing delimiters: import re re....

A Regex based solution >>> my_string_one '[A][B][C]' >>> re.split(r"\[([A-Z])\]", my_string_one)[1:-1:2] ['A', 'B', 'C'] >>> my_string_two '[A][B][C][D][E]' >>> re.split(r"\[([A-Z])\]", my_string_two)[1:-1:2] ['A', 'B', 'C', 'D', 'E'] You can use re.split with the expression \[([A-Z])\ having a capture ...

malloc vs. realloc Rather than allocate, copy, append ... ... consider re-allocate, append. // char* tempFunctionName = (char*)malloc((functionNameLength+2)*sizeof(char)); // strcpy(tempFunctionName, functionName); // tempFunctionName[functionNameLength] = c; // tempFunctionName[functionNameLength+1] = 0; // free(functionName); // functionName = ...

Thank you for the code alternative. I like many of the changes you did: The non-quadratic tokenizer, of course, as well as the use of a stack of the minimum size needed, and the is_number check. I am less fond of the allocation of a temporary array to the possible maximum number of tokens, though, even if the data in the unused elements is not allocated. As ...

Things to improve in the current solution: It is always better to use an integer, parameter for the desired kinds of types. You can still set integer, parameter :: wp = kind(1.d0) to achieve the same result as currently, but you can change it in one place, if you want to. Some reused functionality should be encapsulated into functions. (For example the ...
