Using user input to create conditional statements

Question

Using user input to create conditional statements

I'm currently working on a project involving a textbot that outputs information in the console based on user input. It sounds simple, but I've encountered a frustrating problem that I can't seem to solve. There must be an easy fix for this issue, but it's eluding me.

My goal is to have the textbox recognize a command that includes both the user input and a variable provided by the user. Here is an example of what I'm aiming for:

case "input " + condition {
  //execute code based on 'condition'
}

My inquiry is how can I differentiate between the user input and the specified condition within the textbox? It may sound confusing, but I'm struggling to frame it differently.

Edit: Here's an illustration for clarity:

Textbox input:

"!locate p.actionValue"

Depending on the value assigned to 'actionvalue' by the user, the response should vary like so:

if (actionvalue = 32) {
  //perform an action when actionvalue equals 32
}

The challenge lies in distinguishing between the command and the condition. Any advice or suggestions would be greatly appreciated.

To extract specific information from the input, you can utilize a regular expression and check for certain conditions:

let match;
if (match = input.match(/^!find (.*)/)) {
    let condition = match[1];
    // perform actions based on the condition
}

To make the code more versatile, consider a broader approach:

let match = input.match(/^!(\S+)\s+(.*)/);
if (match) {
    let action = match[1];
    let argument = match[2];
    switch (action) {
        case 'find':
            ...
            break;
    }
}

If you want to extract commands from your text, one way is to split the text using "input " as the delimiter.

// Splitting the text by 'input '
var extractedCommand = inputText.split('input ');
// The desired command can be accessed using extractedCommand[0]

It's important to ensure that the text actually contains 'input ', and consider scenarios like 'input input '.
