创建Mercurial的环境设置文件.在主目录下创建.hgrc文件, 括号内的称为节(Section),如[ui]用来设置usernme的属性.username会想版本哭提交时候记录在日志里 [Extensions]用来激活Mercurial附属的扩展工具,将扩展工具名写入[extensions],我们就可以使用该工具了.有一些工具不但要在Extension中设置,还要在pager中设置pager属性 [ui] username=bpbook bpbook@beproud.jp [extensions] color= pager= [pager] pager=LESS=‘FSRX’ less
