What is the difference between Lex and yacc?
The main difference between Lex and Yacc is that Lex is a lexical analyzer which converts the source program into meaningful tokens while Yacc is a parser that generates a parse tree from the tokens generated by Lex. Generally, a compiler is a software program that converts the source code into machine code.
How install Lex in Linux?

What is Lex in Linux?
The lex utility generates C programs to be used in lexical processing of character input, and that can be used as an interface to yacc. The C programs are generated from lex source code and conform to the ISO C standard. Usually, the lex utility writes the program it generates to the file lex. yy. c.
What is Linux bison?
Bison is a general-purpose parser generator that converts an annotated context-free grammar into a deterministic LR or generalized LR (GLR) parser employing LALR (1) parser tables. As an experimental feature, Bison can also generate IELR (1) or canonical LR(1) parser tables.
What is yacc tool?
Yacc (for “yet another compiler compiler.” ) is the standard parser generator for the Unix operating system. An open source program, yacc generates code for the parser in the C programming language. The acronym is usually rendered in lowercase but is occasionally seen as YACC or Yacc.
What is the use of lex and Yacc?
lex and yacc are a pair of programs that help write other programs. Input to lex and yacc describes how you want your final program to work. The output is source code in the C programming language; you can compile this source code to get a program that works the way that you originally described.
What is Flex in Ubuntu?
flex is a tool for generating scanners: programs which recognized lexical patterns in text. flex reads the given input files, or its standard input if no file names are given, for a description of a scanner to generate. The description is in the form of pairs of regular expressions and C code, called rules.
Is yacc and bison same?
Bison is the GNU implementation/extension of Yacc, Flex is the successor of Lex.
What is yacc bison?
Bison originated as a workalike of a program called Yacc — Yet Another Compiler Compiler. 9. Yacc was written at Bell Labs as part of the very early development of Unix; one of its first uses was to develop the original Portable C Compiler, pcc. The same person, Steven C. Johnson, wrote Yacc and the original pcc.

How to install LEX and YACC in Ubuntu
How to install LEX and YACC in Ubuntu
If you have programming experience in a UNIX environment, you have probably already come across Lex and YACC, or as Linux users know them, Flex and Bison. For those who didn’t know Flex is the implementation of the Lex program, and Bison is the GNU version of the YACC program. These programs are extremely useful for some tasks, so in today’s article we will walk you through installing Lex and YACC on Linux. As an example, we will use the Ubuntu distribution.
Install LEX and YACC in Ubuntu
Open a terminal. To do this, use the keyboard shortcut (Ctrl + Alt + T) . To install Lex (Flex), use the command: sudo apt install flex sudo apt install bison sudo apt install flex bison
Done, now you can use LEX and YACC for your tasks. Still have questions? Write to us in the comments.
how to install Lex and Yacc in Ubuntu?
Use the synaptic packet manager in order to install yacc / lex. If you are feeling more comfortable doing this on the console just do:
sudo apt-get install bison flex
There are some very nice articles on the net on how to get started with those tools. I found the article from CodeProject to be quite good and helpful (see here). But you should just try and search for “introduction to lex”, there are plenty of good articles showing up.
How to Install Lex-Yacc in Ubuntu / LinuxMint easily! Works on all Versions 🙂
Recently, i had to install lex and yacc on quite a few ubuntu/installations because of college practicals exams (15-20 machines approximately) and that really fed me up 🙁 . Installing Lex and Yacc on Ubuntu/LinuxMint isn’t much difficult and is a cake-walk) if you can follow the correct steps as mentioned in this article –
Procedure to install Lex/Yacc on Ubuntu / LinuxMint
Pre-requisites :
An existing Ubuntu / Linux Mint Installation .
A working Internet connection.
Steps –
First of all connect your Ubuntu/LinuxMint to the Internet and Open terminal (you can use the shortcut Ctrl+Alt+t to open the terminal)
to open the terminal) Now in terminal type the following command. (You can check the above image for the screenshot) sudo apt-get update
Now, it will ask for your password – Please type the password for your Linux Account and hit Enter. ( Note : While typing the password nothing will be visible on terminal – it’s normal simply continue typing your password and hit enter when you are done with it)
While typing the password – simply continue typing your password and hit enter when you are done with it) It may also ask for your permissions to update simply type “y” and hit enter , it will update its repositories through the internet, wait till the complete index update gets completed and it presents you with a terminal screen to enter command .
Now , first we will install the Lex package which is called as flex by typing the following command in terminal – sudo apt-get install flex
package which is called as flex by typing the following command in terminal – Again it will , ask for confirmation , simply respond with “y” and hit enter. Lex will be successfully installed , and you will be presented with the terminal screen .
Now, Let’s move on to the installation of Yacc for which we will be using the bison package . Type the following command in the terminal to install yacc – sudo apt-get install bison
for which we will be using the package . Type the following command in the terminal to install yacc – That’s it the Yacc file too will be downloaded and installed , sometimes the Repository servers of bison are down and give errors in such cases you can use any of the following alternatives to install yacc.-
sudo apt-get install byacc sudo apt-get install bison++ sudo apt-get install byacc -j
That’s it it was this much simple 🙂 , Happy Lex and Yacc programming.
If you have any doubts/or want to enquire about any issues/errors feel free to comment, I will be happy to help you 🙂 , also will be adding screenshots to this article once i am done with my practicals.
Introduction to YACC
A parser generator is a program that takes as input a specification of a syntax, and produces as output a procedure for recognizing that language. Historically, they are also called compiler-compilers.
YACC (yet another compiler-compiler) is an LALR(1) (LookAhead, Left-to-right, Rightmost derivation producer with 1 lookahead token) parser generator. YACC was originally designed for being complemented by Lex.
Input File:
YACC input file is divided into three parts.
/* definitions */ …. %% /* rules */ …. %% /* auxiliary routines */ ….
Input File: Definition Part:
The definition part includes information about the tokens used in the syntax definition:
%token NUMBER %token ID
Yacc automatically assigns numbers for tokens, but it can be overridden by
%token NUMBER 621
Yacc also recognizes single characters as tokens. Therefore, assigned token numbers should not overlap ASCII codes.
The definition part can include C code external to the definition of the parser and variable declarations, within %{ and %} in the first column.
and in the first column. It can also include the specification of the starting symbol in the grammar:
%start nonterminal
Input File: Rule Part:
The rules part contains grammar definition in a modified BNF form.
Actions is C code in { } and can be embedded inside (Translation schemes).
Input File: Auxiliary Routines Part:
The auxiliary routines part is only C code.
It includes function definitions for every function needed in rules part.
It can also contain the main() function definition if the parser is going to be run as a program.
The main() function must call the function yyparse().
Input File:
If yylex() is not defined in the auxiliary routines sections, then it should be included:
#include “lex.yy.c”
YACC input file generally finishes with:
.y
Output Files:
The output of YACC is a file named y.tab.c
If it contains the main() definition, it must be compiled to be executable.
definition, it must be compiled to be executable. Otherwise, the code can be an external function definition for the function int yyparse()
If called with the –d option in the command line, Yacc produces as output a header file y.tab.h with all its specific definition (particularly important are token definitions to be included, for example, in a Lex input file).
option in the command line, Yacc produces as output a header file with all its specific definition (particularly important are token definitions to be included, for example, in a Lex input file). If called with the –v option, Yacc produces as output a file y.output containing a textual description of the LALR(1) parsing table used by the parser. This is useful for tracking down how the parser solves conflicts.
Example:
Yacc File (.y)
C
%{ #include
#include #define YYSTYPE double /* double type for yacc stack */ %} %% Lines : Lines S ‘ ‘ { printf ( “OK
” ); } | S ‘
’ | error ‘
‘ {yyerror( “Error: reenter last line:” ); yyerrok; }; S : ‘(‘ S ‘)’ | ‘[‘ S ‘]’ | ; %% #include “lex.yy.c” void yyerror( char * s) { fprintf (stderr, “%s
” , s); } int main( void ) { return yyparse(); }
Lex File (.l)
C
%{ %} %% [ \t] { }
|. { return yytext[0]; } %%
For Compiling YACC Program:
Write lex program in a file file.l and yacc in a file file.y
Open Terminal and Navigate to the Directory where you have saved the files.
type lex file.l
type yacc file.y
type cc lex.yy.c y.tab.h -ll
type ./a.out
Flex (Fast Lexical Analyzer Generator )
FLEX (fast lexical analyzer generator) is a tool/computer program for generating lexical analyzers (scanners or lexers) written by Vern Paxson in C around 1987. It is used together with Berkeley Yacc parser generator or GNU Bison parser generator. Flex and Bison both are more flexible than Lex and Yacc and produces faster code.
Bison produces parser from the input file provided by the user. The function yylex() is automatically generated by the flex when it is provided with a .l file and this yylex() function is expected by parser to call to retrieve tokens from current/this token stream.
Note: The function yylex() is the main flex function that runs the Rule Section and extension (.l) is the extension used to save the programs.
Installing Flex on Ubuntu:
sudo apt-get update sudo apt-get install flex
Note: If Update command is not run on the machine for a while, it’s better to run it first so that a newer version is installed as an older version might not work with the other packages installed or may not be present now.
Given image describes how the Flex is used:
Step 1: An input file describes the lexical analyzer to be generated named lex.l is written in lex language. The lex compiler transforms lex.l to C program, in a file that is always named lex.yy.c.
Step 2: The C compiler compile lex.yy.c file into an executable file called a.out.
Step 3: The output file a.out take a stream of input characters and produce a stream of tokens.
Program Structure:
In the input file, there are 3 sections:
1. Definition Section: The definition section contains the declaration of variables, regular definitions, manifest constants. In the definition section, text is enclosed in “%{ %}” brackets. Anything written in this brackets is copied directly to the file lex.yy.c
Syntax:
%{ // Definitions %}
2. Rules Section: The rules section contains a series of rules in the form: pattern action and pattern must be unintended and action begin on the same line in {} brackets. The rule section is enclosed in “%% %%”.
Syntax:
%% pattern action %%
Examples: Table below shows some of the pattern matches.
Pattern It can match with [0-9] all the digits between 0 and 9 [0+9] either 0, + or 9 [0, 9] either 0, ‘, ‘ or 9 [0 9] either 0, ‘ ‘ or 9 [-09] either -, 0 or 9 [-0-9] either – or all digit between 0 and 9 [0-9]+ one or more digit between 0 and 9 [^a] all the other characters except a [^A-Z] all the other characters except the upper case letters a{2, 4} either aa, aaa or aaaa a{2, } two or more occurrences of a a{4} exactly 4 a’s i.e, aaaa . any character except newline a* 0 or more occurrences of a a+ 1 or more occurrences of a [a-z] all lower case letters [a-zA-Z] any alphabetic letter w(x | y)z wxz or wyz
3. User Code Section: This section contains C statements and additional functions. We can also compile these functions separately and load with the lexical analyzer.
Basic Program Structure:
%{ // Definitions %} %% Rules %% User code section
How to run the program:
To run the program, it should be first saved with the extension .l or .lex. Run the below commands on terminal in order to run the program file.
Step 1: lex filename.l or lex filename.lex depending on the extension file is saved with
Step 2: gcc lex.yy.c
Step 3: ./a.out
Step 4: Provide the input to program in case it is required
Note: Press Ctrl+D or use some rule to stop taking inputs from the user. Please see the output images of below programs to clear if in doubt to run the programs.
Example 1: Count the number of characters in a string
C
%{ int count = 0; %} %% [A-Z] { printf ( “%s capital letter
” , yytext); count++;} . { printf ( “%s not a capital letter
” , yytext);}
{ return 0;} %% int yywrap(){} int main(){ yylex(); printf ( ”
Number of Capital letters ” “in the given input – %d
” , count); return 0; }
Output:
Example 2: Count the number of characters and number of lines in the input
C
%{ int no_of_lines = 0; int no_of_chars = 0; %} %%
++no_of_lines; . ++no_of_chars; end return 0; %% int yywrap(){} int main( int argc, char **argv) { yylex(); printf ( “number of lines = %d, number of chars = %d
” , no_of_lines, no_of_chars ); return 0; }
Output:
How to download and install Bison (GNU Parser Generator) on Ubuntu Linux
You have to install m4 (general purpose macro processor) before installing Bison (GNU Parser Generator). Click here . If you are looking to download and install YACC then you can find complete instructions on ” installing Berkeley Yet Another Compiler Compiler (byacc) on Ubuntu Linux “.
This short tutorial shows you how to download and install Bison (GNU Parser Generator) on Ubuntu Linux Server. The process is very simple. For this tutorial, I’ll be downloading and installing Bison version 2.3. Linux kernel is 2.6.15-26-powerpc. I have used a Mac Mini (powerpc/ppc architecture). GCC version number is 4.0.3. Your configuration may be different from mine but the installation steps below should work fine for most configurations with little or no change at all (including other Linux distributions and even unixes e.g. MacOS X).
Bison (GNU Parser Generator):
According to gnu.org,
“Bison is a general-purpose parser generator that converts an annotated context-free grammar into an LALR or GLR parser for that grammar. Once you are proficient with Bison, you can use it to develop a wide range of language parsers, from those used in simple desk calculators to complex programming languages.”
Before starting, please check to see if there is a latest version available to download. Visit http://www.gnu.org/software/bison/ to find out about the available versions. IMPORTANT: See “Configuring Ubuntu Linux After Installation” to install the development tools required to compile and install bison from source code.
Steps to download, compile, and install are as follows. Note: Replace 2.3 with your version number:
Download Bison (GNU Parser Generator): Run the command below, wget http://ftp.gnu.org/gnu/bison/bison-2.3.tar.gz
Extract files from the downloaded Bison package: tar -xvzf bison-2.3.tar.gz Now, enter the directory where the download bison package is extracted. cd bison-2.3
Now, enter the directory where the download bison package is extracted. Configure downloaded Bison (GNU Parser Generator) package: If you haven’t installed m4 yet then please do so. Click here to read about the installation instructions for m4. Run the commands below to include m4 in your PATH variable. PATH=$PATH:/usr/local/m4/bin/ NOTE: Replace ‘/usr/local/m4/bin’ with the location of m4 binary. Now, configure the source code before installation. You can also install bison with libiconv. ./configure –prefix=/usr/local/bison –with-libiconv-prefix=/usr/local/libiconv/ Replace “/usr/local/bison” above with the directory path where you want to copy the files and folders. Remove ‘–with-libiconv-prefix=/usr/local/libiconv/’ from the command above if you don’t want to install bison with libiconv. Note: check for any error message.
Replace “/usr/local/bison” above with the directory path where you want to copy the files and folders. Remove ‘–with-libiconv-prefix=/usr/local/libiconv/’ from the command above if you don’t want to install bison with libiconv. check for any error message. Compile Bison: make Note: check for any error message.
Install Bison: As root (for privileges on destination directory), run the following. With sudo, sudo make install Without sudo, make install Note: check for any error messages.
That’s it! Bison (GNU Parser Generator) has been successfully downloaded, configured, compiled, and installed on Linux.

Installation
Install XSM Machine Simulator
The compiler’s target code needs to be run on a simulator and the installation steps are given below.
Let us install XSM
Step 1 :
Download XSM Simulator : Version 1
Step 2 :
Extract this file and navigate into the folder xsm_expl through the terminal.
Do the following steps:
1. Type “make”. You may get some warnings and they can be ignored. If you get any fatal error , then install the following dependencies and try running “make” again :
sudo apt-get install libreadline-dev
sudo apt-get install libc6-dev
sudo dnf install readline-devel # for fedora
If any other dependencies are missing (this depends on your system configuration), you have to install the missing dependencies and run “make” again. (Optional) While running “./xsm” after Step 2 if you get this error:
/usr/bin/ld: cannot find -ll collect2: error: ld returned 1 exit status Then you need to install:
sudo apt-get install libfl-dev
and edit the Makefile of xsm_dev folder, to proceed find the line where “-ll” is used as option and update it to “-lfl” to use the “flex” library we installed above. Now you can run “make” again after navigating into the folder xsm_expl through the terminal. If you run into errors pretaining to /usr/include/readline/* , Update xfs-interface/interface.c and include stdio.h before readline headers
2. Type “cd ../xfs-interface/” and type “./init”.
3.(Optional) Add this line #!/usr/bin/env bash as first line to the xsm file in xsm_expl folder. This step is for those who don’t have bash or sh as their “default shell” and therefore may be using other customizable shells like zsh, etc as their default shell. You can check your default shell by using echo $SHELL in terminal.
The usage instructions for the XSM simulator can be found here.
