LGTM : code review 行话

程序员这个行业，不管你是大佬还是小弟，代码code review是必不可少的。那么在git上，大家日常交流的缩写语，往往一下就能看出你道行的深浅，至少是入行时间，哈哈，不要露怯，勇敢的跟大佬过招拆招。

收集了一些实用的缩写，方便大家日常交流(装B)

LGTM  —  Looks good to me，表示认可这次PR，同意merge 合并代码到远程仓库

ASAP -— as soon as possible! 尽快

ACK  —  acknowledgement, i.e. agreed/accepted change

NACK/NAK — negative acknowledgement, i.e. disagree with change and/or concept

RFC  —  request for comments, i.e. I think this is a good idea, lets discuss

WIP：Work In Progress 「进展中」，常见词汇，这里做为 Best Practice 单独提出来，主要针对改动较多的 PR，可以先提交部分，标题或 Tag 加上 WIP，表示尚未完成，这样别人可以先 review 已提交的部分

AFAIK/AFAICT  —  as far as I know / can tell IIRC  —  if I recall correctly

IANAL  — “ I am not a lawyer ”, but I smell licensing issues

IMO  — （In my opinion），在我看来

TL;DR  —  Too Long; Didn’t Read 「太长懒得看」，README 文档常见。

PR  —  Pull request「合并请求」

CR  —  Code Review 「代码审查」

PTAL  —  Please Take A Look. 你来瞅瞅？用来提示别人来看一下

TBR  —  To Be Reviewed. 提示维护者进行 review

TBD  —  To Be Done(or Defined/Discussed/Decided/Determined). 根据语境不同意义有所区别，但一般都是还没搞定的意思。

TBH  —  To be honest 「老实说」

atm  —  at the moment 「现阶段」，
