## 1 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
|
|
|
|
## 2 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
|
|
|
|
### 2.1 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
|
|
|
|
### 2.2 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
|
|
|
|
### 2.3 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
|
|
|
|
## 3 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
|
|
|
|
### 3.1 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
|
|
|
|
### 3.2 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
