lazyclone

lazyclone for git clone

原理

为了偷个懒，折腾好半天

因为clone完成后要cd到新目录，所以比较恶心，而node.js里的child_process是无法切换的，你想啊shell命令是当前子线程里执行，只要线程不变，它可能变么？

node.js里的child_process实际上使用的popen(3)接口

  popen(3) - Linux man page

  Name

  popen, pclose - pipe stream to or from a process

  Synopsis

  #include <stdio.h>

  FILE *popen(const char *command, const char *type);

  int pclose(FILE *stream);
  Feature Test Macro Requirements for glibc (see feature_test_macros(7)):
  popen(), pclose():
  _POSIX_C_SOURCE >= 2 || _XOPEN_SOURCE || _BSD_SOURCE || _SVID_SOURCE

在shell里其实也是一样的

cd $reponame

exec $SHELL

必须exec $SHELL才好使

那么，只剩下最后一招了，把a.sh脚本copy到npm命令所在的目录，然后赋予执行权限，这样就可以像npm一样执行了。

这是npm scripts的另一个极端的做法。

Install

npm i -g lazyclone

now, you can use clone command in terminal.
