Review Questions

1. How is a source code editor different from an IDE

Integrated Development Environments

Source code editors

• editor applications to help software development
• provide features that help editing code
  • auto indent, bracket matching, syntax hl, auto completion, rapid navigation
  • run/test code

Integrated dev env

• allow you to remain within one application when carrying out software development work
  • can edit source files
  • can compile source files
  • can run debugger
  • integrates version management
• some attach tools to running applications

LSP - syntax highlighting

• allows IDE's to communicate with a "language enging"
• ides dont need

shift from syntac to semantics e.g.,

• vs code chck file on opening
  • lsp reports type mismatches
• rich editor functionality
  • autocompletion with appropriate context
  • information displayed on mouse hover
  • jumping to definitions on mouse hover
  • safe refactoring -> better than blind search and replace
  • diagnosticso -> e.g., display results of unit tests within editor

Navigation

• within files
  • bracket matching
  • block folding
• multi file
  • multiple files at the same time
  • rapidly jump between files
  • search across all files
• collaboration e.g., live sharing

Modern IDEs

• microsoft
  • vscode -> free open source, highly popular
  • visual studio -> integrates mobile and cloud development
• java enivronments
  • eclipse - early leader in java, supports other languages
  • netbeans -> also includes web dev tooling
• jetbrains -> IntelliJ IDEA, pycharm, phpstorm
• google's android studio -> official android IDE
• apple's Xcode -> free, macOS/iOS focus

Early programming

• dedicated machines
  • punched card programmer: separate machine from computer than reads cards
• punched cards recore code and or data in binary
  • grid of positions, each representing a binary digit (bit)
  • each position in punches out, or not
• analgogue electronic devices where you phsyicall wire things up
  • gaining interest now for use in machine learning

Bootstrapping

• already built tools can be used to builder better tools for building better tools etc.
• e.g., first assembler was made in maching code. But after that they could use the assember to make a better assembler

Early dev environments

• command line based
  • text based terminals
  • command shell is the running application
• Can use terminal to drive interactive languages
  • can edit, store software code
  • can compile cose and run resulting executables
• it is still practical to do software development this way
  • vim etc
