Implement the command tokenizer

[nanafox]

For this task, your job will be to break a string into the required substrings based on a given delimiter. This function must return a string array. The function to use is

#include "liteshell.h"

char **tokenize(const char *str, const char *delim);

This function will utilize the strtok function. Ensure you are handling memory correctly and checking for edge cases. This function will be what everyone will use for anything that requires tokenization for the entire shell. For this reason, ensure you are thinking outside of the box and bringing out something very efficient and long-lasting.

When delimiter is NULL, assume spaces and tabs. Also, terminate the array before returning it.

Example usage:

int i;
char *cmd = "Hello world";

/* call the function to tokenize on spaces */
char **cmd_array = tokenized(cmd, NULL);

/* print the array */
for (i = 0; cmd_array[i] != NULL; i++)
    printf("%s\n");

Expected output:

Hello
World

@LawsonLawson @Kofi-Awuah2020... Good morning, I trust your night was awesome. The task has been rolled out for us to tackle, I hope we get it done between today and tomorrow, may I know our schedule so that we have our first discussion and share ideas of how we do the task. Looking forward to hearing from you

[OmondiHillaryA1997]

Good Morning too Rid, I appreciate you contacting us.

Allow me share my Weekly schedule unless things change.

Monday to Friday: 11:30Am to 9PM EAT I attend to part time work. Monday to Friday: Morning hours before 11 AM EAT attend to ALX_SE Curriculum Saturday and Saturday: Fixtures are made depending on how the week has been but having this Collaboration going beyond Codemind Schedule can be beneficial.

Roughly, that how my Weekly Sketch looks like. Regards.

Sounds good!

[Kofi-Awuah2020]

Quick question: On which platform will the meeting be taking place? Also here is my contact details incase anyone wants to reach out: 0241301611 (I use this same number for WhatsApp) kofiawuah.a@gmail.com

[akoredera]

@Kofi-Awuah2020 it's better we have a call, using google meet

It's almost time let's get set and be available Thanks

char _strtok(char str, const char *delim)

check the first argument (str) if not NULL assigned str to static char input_str; initialize input_str to char token; strchr(input_str, delim[0]) and return the output to char *tempStr check if tempStr is not NULL check the difference between the strlen of input_str and tempStr and save to str_len_diff strncpy(token, input_str, str_len_diff) add null terminator to token - token[str_len_diff] = '\0'; increase tempStr by 1 index; return tempStr value to input_str

What's this one doing, please? I'm seeing a different function prototype

[theAstralProgrammer0]

• Guys, please let's follow the prototypes so we can have a uniform codebase.
• You also should handle error situations such as failure to allocate memory for a buffer and related errors so that it corresponds with our function checks
• For instance, on my end, we're assuming that if tokenizer fails, it will return NULL
• We use this return value to handle errors on our end as well.
• You can look through #28 to see our expectations of the tokenizer function and how it is applied in handling the alias command for perspective.
