8085-emulator's Issues

8085 Documentation Web Interface

Assigned to : Anurag Timilsina
Look into the issue #1 for json format @AyushPaudel will provide
and create a web app that takes in the JSON format as defined on the issue and lists them out.
Basic features should include :

1. ability to search instruction
2. list out instruction based on different addressing mode i.e immediate addressing, implied addressing etc
3. list out instruction based on type: i.e data transfer , arithmetic
4. styling should be drawn from this scheme
   

This file contains the color palette for the image above
https://github.com/voidash/ReactNotes/blob/95627da06d254475d320a8e97a931c398ae6cf07/8086-landing-page/src/index.scss#L3

Bug: Labels have to be defined before they can be used.

The command

JMP test
test: MOV A, B

doesn't work as JMP command will look for map between label (test) and line number it occurred. Since test is in line no 3. line no 2 will have no idea about line 3.
Add preprocessor for JMP, JC, JZ , JNZ etc

8085 opcode documentation support

Assigned to: Ayush Paudel
Here are the list of all the instructions that needs documentation. Head to the file given below and please create JSON file

8085-Emulator/src/assembler/assembly.lalrpop

Line 22 in 906fa61

pub Instruction : &'input str = {

The format for JSON file should be

{ 
	instructions : [
	{
		"opcode" : "mov",
		"description" : "mov from one register to another register. Valid registers are a, b, c ,d , e, h, l",
               "syntax" : "mov [register] , [register]",
		"machineCycle" : "3",
                "addressingMode": "register addressing",
		"example" : "mov a, b",
               "type" : "data transfer" 
	}, 
       {  
		"opcode" : "mvi",
		"description" : "immediate move   Valid registers are a, b, c ,d , e, h, l",
               "syntax" : "mvi [register], value"
		"machineCycle" : "3",
   "addressingMode": "implied addressing",
		"example" : "mov a, b",
                "type" : "data transfer",
               
	}, 
	]
}
