Project description

A collection of some of the scripting languages I learned at CSU. Included in the project is 3 different programs, that each are in their own respective language. The languages are as follows: Shell, Perl, and Python. Each acomplish a different task and are here to demonstrate mastery of a variety of problems/concepts.

• Shell: Regular Expression when searching through large data sets
• Python: Simple math calculations and utilizing classes/instancing
• Perl: Hashes and reading information from a file

Regular Expression Program that does the following to a text file:

• Prints all occurences of christmas at the start of the line only
  
• Prints the count of words that end with ‘ing’
• Prints words that start with an uppercase M and ends in lowercase e, then sorts them alphabetically
• Calculates and prints percentage of words that start with a vowel
• No input is needed for the execution of the program

Right Triangle Program does the following:

• Demonstrates classes and use of instancing when working with objects
• Does both surface area calculation and hypotenous calculations of a given triangle
• Then creates a second triangle using the same methods, but shows the different outputs
• Prints all results to the terminal after execution, no input is needed

Perl Bowling Program does the following:

• Reads input from a list of scores from a scores.txt file and converts the key-value pairs into a hash
• Calculates the average score of all players and writes to average.txt
• Sorts the players based off score from lowest to highest and writes to sorted.txt
• Calculate the winner based on who has the highest score, writes to winner.txt

How to compiles / run the programs

There are no executables, so Python and Perl need their source files to be put into a compiler. Shell can be run on bash on linux, or with a online compiler as well.

Shell Program:

• Go into any normal linux terminal and cd into the directory with the file
• Give permissions chmod 755 lab02.sh
• Then run it with ./lab02.sh
• Requires a file named words.txt, but can be filed with anything the user wants in terms of content (1 word per line).

Python Program:

• Go to this link for an online python compiler: https://www.onlinegdb.com/online_python_compiler
• Copy the source code or simply upload the file to the site (RightTriangle.py is main)
• Press the execute button at the top, the code will output at the bottom in the terminal

Perl Program:

• Go to this link for an online perl compiler: https://www.onlinegdb.com/online_perl_compiler#
• Copy the source code or simply upload the files to the site. Only requires lab04.pl and scores.txt to function. (lab04.pl is main)
• Press the execute button at the top, the code will output at the bottom in the terminal

Image Examples

Below are screenshots taken from the three programs. They do not show source code, but do show the output/results of all programs. Considering there is no input for the programs there is no notable UI elements to document. The Perl examples are screenshots of the files created and are Figures 1-4. Figure 5 is the terminal output for python after running the triangle program. Figures 6-7 are linux terminal output for the bash program and its commands. Refer to the README.md file for any further questions about the functionality of each program.

Fig 2. The average of inputted scores of the Perl Program

Fig 3. The Perl Sorted list of players based on the scores

Fig 4. The Perl score winner based off default values

Fig 5. Python testing and calculations of a right triangle

Fig 6. First half of Shell output: words that start with Christmas, count of words ending in -ing and words that start with M and end an e (sorted)

Fig 7. Second half of Shell output: last portion of words that start with M and end an e, and percentage of words with a starting vowel

3. Additional Considerations

This is a compilation of programs that come together to form a larger project. Its much easier to utilize online compilers with how many languages the project switches between. That being said the Shell program’s text file that holds sample words is too big for most online compilers. In that case, as mentioned in instuctions, you would have to utilize a linux machine to run the shell program. Alternatively, you can simply provide your own words.txt to run from.

For more details see README.md file.
