utils.ts

Overview

The utils.ts file provides utility functions related to the parsing status within the application. Currently, it contains a single function isParserRunning that checks whether a parser is in the "running" state based on a predefined enumeration RunningStatus. This utility helps centralize status checks, promoting code reuse and improving readability wherever parser status evaluation is needed.

Functions

isParserRunning

export const isParserRunning = (text: RunningStatus) => boolean;

Description:
Determines whether the provided status indicates that the parser is currently running.

Parameters:

• text (RunningStatus): An enum value representing the current running status of the parser.

Returns:

• boolean: Returns true if text is equal to RunningStatus.RUNNING, otherwise returns false.

Usage Example:

import { RunningStatus } from './constant';
import { isParserRunning } from './utils';

const currentStatus = RunningStatus.RUNNING;

if (isParserRunning(currentStatus)) {
  console.log('Parser is currently running.');
} else {
  console.log('Parser is not running.');
}

Implementation Details

• The function performs a strict equality check (===) between the input text and the constant RunningStatus.RUNNING.

• The RunningStatus enum is imported from the './constant' module, which is presumed to define various statuses related to the parser lifecycle.

• The use of an enum helps ensure type safety and self-documentation of possible statuses.

Interaction with Other Parts of the System

• Dependency: This file depends directly on the RunningStatus enum from the constant.ts (or similar) file, which must define parser states such as RUNNING.

• Usage Context: The utility function is intended to be used wherever the application needs to check if a parser (or similar process) is active. This encourages consistent and centralized status evaluation logic.

• Potential Consumers: Components, services, or modules responsible for managing or displaying parser states may import this utility for status checks.

Summary

The utils.ts file is a lightweight utility module focused on parser status evaluation. It exports a single, straightforward function that checks if the parser is running by comparing a status enum. This utility enhances code maintainability by abstracting status checks behind a named function, reducing the risk of inconsistent comparisons across the codebase.
