Description

HTML to LaTeX Converter
Problem statement
This is your first assignment in the COP 701 course.In this assignment your main objective is to convert a HTML document to an equivalent LaTeX document.
In pursuance of this objective, you will have to write a HTML to LaTeX parser from scratch.
The features(tags) of HTML which you all need to consider are:-
head body
title a, href font: size center br
p
h1, h2, h3, h4 ul, li, ol, ul, dl, dt, dd div
u, b, i, em, tt, strong, small, sub, sup
img: src, width, height, figure, figcaption table, caption, th, tr, td
Some more commands, mathematical symbols, math-mode operators(for extra credit)
Workflow and subtasks The entire assignment can be divided into the following sub-tasks:
Learn about HTML and LaTeX in brief.
Write a lexer i.e to do a lexical analysis of your HTML code and generate a string of tokens.
Programs that you can use: flex, jflex
Do not use any available libraries to parse the html.
Parse the sequence of tokens using parser such as yacc, CUP, ANTLR, bison (C++ or Java) Generate an AST(Abstract Syntax Tree) of your HTML code. link Map it to an equivalent AST of LaTeX.
Generate the equivalent LaTeX code which can be compiled to a PDF using TexMaker
Links to important resources
Know about Flex tool and performing lexical analysis using that.
Some more resource regarding Flex.
Introduction to an Abstract Syntax Tree.
Bison parser generator
YACC parser generator
Logistics
You are free to code in any programming language.
This is an individual assignment (30 Marks)
Also, create a run.sh file where the first argument will be the name of the html file and the second argument will be the name of the output tex file. We will run the command ./run.sh input.html output.tex during the demo.
Submission will be made on Moodle. You need to submit all your code (parser, translator) and a pdf format report. Compress all these in a tar file and upload on Moodle.
You will be graded on the output of your code, the coding style and your viva/presentation.
Marks distribution: Coding style – 25% , Demo – 75%
We will be testing on hidden test cases during the demos
