rotp (Revenge of the Pancakes)

Welcome to rotp

This was a fun exercise and I enjoyed working on it. So thank you!

Usage

This application was designed around using the stdin to pipe test files directly to the app. The exercise talked about "Lines of input" I interpreted this to mean that it would take a multi line input. Stdin seems like the natural way to accomplish this.

Command Help

Running rotp without any input will give you a little bit of help

Nothing to process
This command is designed to be used with a pipe
Example: cat filename | rotp
For for help with other options use -h

More help can be found by using the command with the -h flag

rotp -h

Flags

• -gen-test-file - this will cause the app to output a randomly generated test file that you can then pipe back in the the app for testing.

• -test-file-name - The file name for the test file being generated

• -cases - The number of cases to include in the test app. This needs to be a number between 1 and 100 according to the excersise documentation

• -dataset-size - The test file can be generated with either Large or Small datasets. This parameter will accept either small or large as an argument. small will produce test cases with a length of 1 to 10 large will produce test cases with a length of 1 to 100

• -print-strings - The normal output of the app is a list formatted as

   Case #1: 1 
   Case #2: 1 
   Case #3: 2 
   Case #4: 0 
   Case #5: 3 
  

  the -print-strings flag will include the string that was tested. changing the output to be

   Case #1: 1 -
   Case #2: 1 -+
   Case #3: 2 +-
   Case #4: 0 +++
   Case #5: 3 --+-
  

• -test-string will allow you to send the app a single string for testing, this needs to be formatted as a stack specified in the documentation

    + for face - for blank between 1 and 100 characters in length
  

Examples

Generate a test file with 10 cases and small datasets.

rotp -test-file-name first.txt -gen-test-file -cases 10 -dataset-size small

processing a file with test cases.

cat first.txt | rotp

processing a file with test cases with the case string included in the output

cat first.txt | rotp -print-strings

sending a single string to the app for testing

rotp -test-string +--+--+

Compiling

go build

or

go install

the app can also be run with go run

go run main.go -test-file-name first.txt -gen-test-file -cases 10 -dataset-size small

cat first.txt | go run main.go

Tests

Tests can be run with the go test tool

go test ./...
