From 53cbd0564f98b33d2dc67512a77e8d5f056a6109 Mon Sep 17 00:00:00 2001 From: Rich Trott Date: Wed, 3 Feb 2016 12:27:40 -0800 Subject: [PATCH] tools: lint for spacing around unary operators MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Enable `space-unary-ops` in `.eslintrc`. This prohibits things like: i ++ // use `i++` instead typeof(foo) // use `typeof foo` or `typeof (foo)` instead Ref: https://github.com/nodejs/node/pull/4772#discussion_r51732299 PR-URL: https://github.com/nodejs/node/pull/5063 Reviewed-By: Colin Ihrig Reviewed-By: Michaël Zasso Reviewed-By: Roman Reiss Reviewed-By: James M Snell --- .eslintrc | 2 ++ lib/timers.js | 2 +- test/gc/test-http-client-connaborted.js | 2 +- test/gc/test-http-client-onerror.js | 2 +- test/gc/test-http-client-timeout.js | 2 +- test/gc/test-http-client.js | 2 +- test/gc/test-net-timeout.js | 2 +- test/parallel/test-child-process-exec-buffer.js | 4 ++-- test/parallel/test-fs-read-stream-inherit.js | 2 +- test/parallel/test-fs-read-stream.js | 2 +- test/parallel/test-http-byteswritten.js | 2 +- test/parallel/test-http-date-header.js | 2 +- test/parallel/test-http-response-multiheaders.js | 2 +- test/parallel/test-http-set-trailers.js | 2 +- test/parallel/test-https-byteswritten.js | 2 +- test/parallel/test-vm-debug-context.js | 4 ++-- test/sequential/test-cluster-listening-port.js | 2 +- 17 files changed, 20 insertions(+), 18 deletions(-) diff --git a/.eslintrc b/.eslintrc index e4dd84b8893da0..9f117dbacecb8a 100644 --- a/.eslintrc +++ b/.eslintrc @@ -81,6 +81,8 @@ rules: space-after-keywords: 2 ## no leading/trailing spaces in parens space-in-parens: [2, "never"] + ## no spaces with non-word unary operators, require for word unary operators + space-unary-ops: 2 # ECMAScript 6 # list: http://eslint.org/docs/rules/#ecmascript-6 diff --git a/lib/timers.js b/lib/timers.js index 543a1bf601c7ea..c15b58a17e9608 100644 --- a/lib/timers.js +++ b/lib/timers.js @@ -318,7 +318,7 @@ function unrefdHandle() { Timeout.prototype.unref = function() { if (this._handle) { this._handle.unref();
