Require or disallow spaces following keywords (space-after-keywords)

Some style guides will require or disallow spaces following the certain keywords.

if (condition) {
    doSomething();
} else {
    doSomethingElse();
}

if(condition) {
    doSomething();
}else{
    doSomethingElse();
}

Fixable: This rule is automatically fixable using the --fix flag on the command line.

Rule Details

This rule will enforce consistency of spacing after the keywords if, else, for, while, do, switch, try, catch, finally, and with.

This rule takes one argument. If it is "always" then the keywords must be followed by at least one space. If "never" then there should be no spaces following. The default is "always".

The following patterns are considered problems:

/*eslint space-after-keywords: 2*/

if(a) {}         /*error Keyword "if" must be followed by whitespace.*/

if (a) {} else{} /*error Keyword "else" must be followed by whitespace.*/

do{} while (a);  /*error Keyword "do" must be followed by whitespace.*/

/*eslint space-after-keywords: [2, "never"]*/

if (a) {}        /*error Keyword "if" must not be followed by whitespace.*/

The following patterns are not considered problems:

/*eslint space-after-keywords: 2*/

if (a) {}

if (a) {} else {}

/*eslint space-after-keywords: [2, "never"]*/

if(a) {}

Version

This rule was introduced in ESLint 0.6.0.
