this a ruby based linter for CSS files. it provides feedback about syntax errors in CSS files. I would like to mention that I was inspired by Stylelint, that's why you will find that the output is a bit similar and maybe the choice of colors to.

This version of the CSS Beginner Linter reads a css file provided in the command line like so:

ruby bin/main.rb tests/invalid.css

This CSS linter will catch and display the following syntax errors in the console if there is any:

• Unknown word
• Unexpected whitespace before '}'
• Unexpected whitespace after '}'
• Invalid selector go learn some CSS bro O.o
• Unexpected whitespace before '{' only one space is allowed
• Unexpected whitespace at end of line
• Expected newline after '{'
• Expected one space before '{'
• Unexpected whitespace in pseudo-class after the colon
• Missing space after the colon in the declaration
• Unexpected whitespace after the colon in the declaration, expected only one space
• Missing simi-colon at the end of the declaration
• Unexpected whitespace at end of the line of the declaration
• Unexpected empty line, expected only one empty line
• Unexpected whitespace before selector

so as I mentioned earlier the CSS file you can put it where ever you want but with one condition which you want to target by the command line as I showed you, here is a couple of examples how the linter works:

First of all, you need to have the linter files on your computer. You can get them either cloning this repository or downloading its contents directly

• To clone the repo, go on the project's Github page, click on "Clone or download", copy the contents of the text box, and then run git clone "repo" on the command line, where "repo" is the text you just copied.
• If you want to download it directly instead, go on the project's Github page, click on "Clone or download", and then on "Download ZIP". After this, you need to extract the contents of the zip file on your computer.

Once you have the files on your computer, go on the command line and navigate to the linter directory. Once there :

• create you own CSS file inside the project and fell it with whatever content but please be gentile don't write complex CSS selectors otherwise the program will fail.
• open the terminal window and then type in bundle install to install a ruby colorize lib that gives a good looking output.
• Run the linter directly from the root of the project directory, using the following command ruby ./bin/main.rb .test/invalid.css keep in mind that you can change .test/invalid.css to the location of the file that you have created.

Any contribution is welcomed in this project, you need only to take on consideration one thing which is to write your own test cases if you added new functionality to the program. so all the test cases were written with RSpec inside spec/parser_spec.rb file if you created a new class add another file inside the same folder. and finally, to run the tests you will need to open the terminal and cd into the directory of that project and run the following command: rspec
