node.js堆栈跟踪行中的冒号后面的第二个数字是什么意思？ [英] What does the 2nd number after the colon in a node.js stack trace line mean?

问题描述

在node.js堆栈跟踪中总是有两个数字，然后行号为a：和另一个数字。在下面的例子中，第一行有faye-redis.js：153：36，153是文件中发生错误的行号，但是数字是什么：36是什么意思？

In a node.js stack trace there are always two numbers, the line number then a : and another number. In the example below, the first line has faye-redis.js:153:36 and 153 is the line number in that file for where the error is occurring, but what does the number :36 mean?

node_modules/faye-redis/faye-redis.js:153:36 • publish.notify
node_modules/faye-redis/faye-redis.js:72:16 • clientExists
node_modules/redis/index.js:532:9 • try_callback
node_modules/redis/index.js:614:13 • return_reply
node_modules/redis/index.js:266:14 • RedisClient.init_parser
events.js:96:17 • EventEmitter.emit
node_modules/redis/lib/parser/hiredis.js:43:18 • execute
node_modules/redis/index.js:488:27 • on_data
node_modules/redis/index.js:82:14 • none
events.js:96:17 • EventEmitter.emit
net.js:397:14 • onread

推荐答案

是行（行号），第二个是列（行上的字符）。在Javascript中，许多编码器通常在closures等人的单行上嵌入大量代码，或者使用诸如YUI压缩程序之类的缩写器，因此它通常是相关的信息。

The first number is the row (line number), the second is the column (character on line). In Javascript many coders habitually nest a lot of code on a single line with closures et al, or use minifiers like YUI compressor, so it's often rather relevant information.
