I need to write a task in package.json. It looks like this:
"nyc": {
"all": true,
"include": [
"src/main/**/*.tsx" // here i need to match all camelCase file names
]
},Here"src/main/**/*.tsx" i need to match all camelCase titles of files.
ex: correct "src/main/**/catBlack.tsx", "src/main/**/carBlack.tsx"
not correct "src/main/**/cat.tsx", "src/main/**/test-file.tsx"
Who can help?
You can create a function to check if a string is camelCase using regex
function isCamelCased(str){
const rgx = new RegExp('[a-z]{1,}([A-Z][a-z]{1,}){1,}$');
return rgx.test(str);
}
you may want to create another function to remove the path and file extension:
function getFileName(str){
let file;
// remove the path
file = str.split('/');
file = file[file.length -1 ];
// remove the extention
return file.split('.')[0];
}
Test:
const arr = [
'/main/camelCase.txt',
'/main/CamelCase.txt',
'/camel.txt',
'/main/camel-case.txt',
'/main/camel2Case.txt',
'/main/camelCase2.txt',
''
]
let file;
arr.forEach((str) => {
file = getFileName(str);
console.log(`${file} => ${isCamelCased(file)}`);
});
output:
"camelCase => true"
"CamelCase => true"
"camel => false"
"camel-case => false"
"camel2Case => false"
"camelCase2 => false"
" '' => false"
