在Linux上创建网页版的webrev

在Sun/Oracle工作了N(>12)年后,对网页版的webrev工具甚为喜欢,因为其易用性确实非常非常好。幸运的是,有工程师将webrev工具放到了GitHub上,而且支持git。 下面给出使用webrev工具创建网页版webrev的全过程。 当然,首先保证git在Linux(我用的是Ubuntu14.04)上已经安装好了。

第1步: Clone webrev from here

veli$ cd /var/tmp
veli$ git clone https://github.com/joyent/webrev.git
Cloning into webrev...
remote: Counting objects: 27, done.
remote: Total 27 (delta 0), reused 0 (delta 0), pack-reused 27
Unpacking objects: 100% (27/27), done.
Checking connectivity... done.

veli$ tree webrev
webrev
├── bin
│   ├── wdiff
│   ├── webrev
│   └── which_scm
├── etc
│   ├── its.conf
│   └── its.reg
└── README.md

第2步: Add webrev/bin to PATH

veli$ export PATH=/var/tmp/webrev/bin:$PATH
veli$ type webrev
webrev is /var/tmp/webrev/bin/webrev

第3步: Set up apache2

veli$ sudo apt-get install apache2
veli$ sudo service apache2 status
veli$ sudo cd /var/www/html; ln -s /var/tmp t
veli$ sudo vim /etc/apache2/apache2.conf # add "ServerName localhost:80"
veli$ sudo service apache2 restart

第4步: clone my source code and update something

veli$ git clone https://github.com/idorax/vCodeHub.git
Cloning into vCodeHub...
remote: Counting objects: 359, done.
remote: Compressing objects: 100% (100/100), done.
remote: Total 359 (delta 58), reused 0 (delta 0), pack-reused 254
Receiving objects: 100% (359/359), 7.85 MiB | 1.61 MiB/s, done.
Resolving deltas: 100% (164/164), done.
Checking connectivity... done.

Now update a file,

veli$ cd /var/tmp/sandbox/vCodeHub/sharpsword/c
veli$ vi sudorax.c

第5步: commit changes

veli$ git commit -a
  1 05/14/2017: demo to use webrev
  2 # Please enter the commit message for your changes. Lines starting
  3 # with # will be ignored, and an empty message aborts the commit.
  4 # On branch master
  5 # Your branch is up-to-date with origin/master.
  6 #
  7 # Changes to be committed:
  8 #       modified:   sudorax.c
  9 #

veli$ git show

        return sum;
 }

第6步: create webrev

veli$ webrev
WARNING: codereview(1) not found.
   SCM detected: git
 File list from: git ... Done.
      Workspace: /var/tmp/sandbox/vCodeHub (at eb08966d562c)

                 patch cdiffs udiffs wdiffs sdiffs frames old new

     index.html: Done.

第7步: 在firefox里访问webrev

veli$ egrep 127.0.0.1 /etc/hosts
127.0.0.1    localhost
127.0.0.1    idorax

于是访问 http://idorax/t/sandbox/webrev

多么熟悉的代码比对页面,倍感亲切呀:-)

结束语: 能在家里的Linux上用上webrev,实在是太幸福了!归根结底就一句话, 感谢opensolaris, 感谢illumos!
