Use a keyboard as a main input device

Use a computer with character devices

Tradition of CLI systems

"TSS" on mainframe machines

Share a single mainframe machine

"Minicomputers"

Unix "shell"

Basic on Apple II and other PCs

"Command prompt" on DOS

"Mini computer" by DEC

Digital Equipment Corporation

PDP11(1970), VAX11(1976)

VMS OS

VAX11

1977 @ Apple

The first personal computer with color bitmap display

http://gyazo.com/19acdfe09dfaf34b2015ec4c926936e8.png

Unix "shell"

Terminal.app on Mac

Demo: Unix terminal

Basic CLI process

REPL (Read-Eval-Print Loop)

code:cli

while true do

display prompt and wait for user input

e.g. C>

the user enters a command and types the return key

the computer receives the string and execute

end

Current date is calculated and sent back to the terminal

Current date is displayed

Contributions of Unix

C language

Full-duplex communication

Users don't have to wait for computers

Regular expressions

Redirections

Object-oriented input/output

All devices treated the same

Serial communication device

For 'dumb' terminals

Simple machine like a typewriter

Send characters hit by user

Show characters sent from computer

VT100 (DEC)

CLI-based programming

http://gyazo.com/28678b9ca87920163df678bfd3b0d4fc.png

"Screen editor"

c.f. "Line editor"

Emacs, Vi, ...

Current popular editors

Move cursor to anywhere by typing keys

No pointing device

Use "escape sequeences" of the terminal

Merits of CLI

Easy to develop

Users and computers work the same way

Interface to a mail server (SMTP)

GUI version of DOS

Merits of GUI

Direct manipulation

Contiinuous

Reversible

Concrete

Can't use this while driving a car

Continuity / Undo

When the user do something, the computer reacts immediately

The user can undo all operations

Not all devices behave like this

Switches

Evolution of GUI

30+ years after the invention of menus and scrollbars

Slight gradual improvements

GUI and object-oriented programming

Make GUI widgets as objects

Windows

Menus

...

GUI toolkits

GUI libraries written in OO language

This is THE mainstream at this moment

Interface builder

Edit GUI objects interactively

Evolution of computers

Evolution of computers and programs

No progress in these 30 years?

Cheaper / smaller / faster

Why don't we create completely new things?

Summary

Big leap from CLI to GUI at PARC (197x)

Continuous / reversible

No big invention after that

Same GUI is used for smartphones and tablets

Less and less user operations

New "idioms" required
