ESLintEnforce padding within blocks (padded-blocks)
Some style guides require block statements to start and end with blank lines. The goal is to improve readability by visually separating the block content and the surrounding code.
if (a) {
b();
}
Since it’s good to have a consistent code style, you should either always write padded blocks or never do it.
Rule Details
This rule enforces consistent padding within blocks.
This rule takes one argument. If it is "always" then blocks must start and end with a blank line. If "never"
then all blocks should never start or end with a blank line. The default is "always".
The following patterns are considered problems when set to "always":
/*eslint padded-blocks: [2, "always"]*/
if (a) { /*error Block must be padded by blank lines.*/
b();
} /*error Block must be padded by blank lines.*/
if (a) { b(); } /*error Block must be padded by blank lines.*/
if (a)
{ /*error Block must be padded by blank lines.*/
b();
} /*error Block must be padded by blank lines.*/
if (a) {
b();
} /*error Block must be padded by blank lines.*/
if (a) { /*error Block must be padded by blank lines.*/
b();
}
if (a) { /*error Block must be padded by blank lines.*/
// comment
b();
}
The following patterns are not considered problems when set to "always":
/*eslint padded-blocks: [2, "always"]*/
if (a) {
b();
}
if (a)
{
b();
}
if (a) {
// comment
b();
}
The following patterns are considered problems when set to "never":
/*eslint padded-blocks: [2, "never"]*/
if (a) { /*error Block must not be padded by blank lines.*/
b();
} /*error Block must not be padded by blank lines.*/
if (a)
{ /*error Block must not be padded by blank lines.*/
b();
} /*error Block must not be padded by blank lines.*/
if (a) { /*error Block must not be padded by blank lines.*/
b();
}
if (a) {
b();
} /*error Block must not be padded by blank lines.*/
The following patterns are not considered problems when set to "never":
/*eslint padded-blocks: [2, "never"]*/
if (a) {
b();
}
if (a)
{
b();
}
