Tools & Facilities in IDEs (Cambridge (CIE) O Level Computer Science): Revision Note

Tools & Facilities in IDEs

What is an IDE?

• An Integrated Development Environment (IDE) is software designed to make writing high-level languages more efficient

• IDEs include tools and facilities to make the process of creating/maintaining code easier, such as:

  • Editor

  • Error diagnostics

  • Run-time environment

  • Translators

Editor

• An editor gives users an environment to write, edit and maintain high-level code

• Editors can provide:

  • Basic code formatting tools - changing the font, size of the font and making text bold etc

  • Prettyprint - using colour to make it easier to identify keywords, for example 'print', 'input' and 'if' in Python

  • Code editing - auto-completion and auto-correction of code, bracket matching and syntax checks

  • Commenting code - allows sections of code to be commented out easily to stop it from being run or as comments on what the program is doing

Error-diagnostics

• Tools that help to identify, understand and fix errors in code, such as:

  • Identifying errors - highlight particular areas of code or provide direct error messages where the error may have appeared e.g. indentation errors etc

  • Debugger -  provide a 'step through' command which provides step by step instructions and shows what is happening to the code line by line, useful for finding logic errors

Run-time environment

• Gives users the ability to run and see the corresponding output of a high-level language

Translator

• Built in to compile or interpret code without the need for an extra piece of software
