howdoi-通过命令行快速得到编程答案的python工具

howdoi是通过命令行快速得到编程答案的python工具。

您是否会不断通过搜索引擎以了解如何执行基本的编程任务？假设您想知道如何在bash中格式化日期。当您只需要停留在控制台中并询问howdoi时，就不需要打开浏览器去搜索结果了（可能会分散注意力）。例如：

$ howdoi format date bash> DATE=`date +%Y-%m-%d`

示例

$ howdoi print stack trace python> import traceback>> try:>     1/0> except:>     print '>>> traceback <<<'>     traceback.print_exc()>     print '>>> end of traceback <<<'> traceback.print_exc()$ howdoi convert mp4 to animated gif> video=/path/to/video.avi> outdir=/path/to/output.gif> mplayer "$video" >         -ao null >         -ss "00:01:00" \  # starting point>         -endpos 10 \ # duration in second>         -vo gif89a:fps=13:output=$outdir >         -vf scale=240:180$ howdoi create tar archive> tar -cf backup.tar --exclude "www/subf3" www
