生成 tags 文件

使用 -R/--recurse 在源文件根下执行，就会生成 tags 文件

[root@h102 forklift_etl-1.2.2]# pwd
/usr/local/rvm/gems/ruby-2.3.0/gems/forklift_etl-1.2.2
[root@h102 forklift_etl-1.2.2]# ls
bin  example  forklift_etl.gemspec  forklift.jpg  Gemfile  Gemfile.lock  lib  LICENSE.txt  Rakefile  readme.md  spec  template
[root@h102 forklift_etl-1.2.2]# ctags -R *

[root@h102 forklift_etl-1.2.2]# wc tags

[root@h102 forklift_etl-1.2.2]# head -n 20 tags

[root@h102 forklift_etl-1.2.2]#

Tip: 在包含有tags文件的目录中，就可以直接使用 vim 进行定位了，也可以将 tags 文件写到 vimrc 中，这样就不用局限于当前路径

直接定位

使用 vim -t <tag> 来定位标记

[root@h102 forklift_etl-1.2.2]# vim -t forklift
...
...
...

会获得所有此标记的定义

  # pri kind tag               file
  1 F   f    forklift          lib/forklift/base/logger.rb
               class:Forklift.Base.Logger
               def forklift
  2 F   f    forklift          lib/forklift/base/mailer.rb
               class:Forklift.Base.Mailer
               def forklift
  3 F   f    forklift          lib/forklift/base/pid.rb
               class:Forklift.Base.Pid
               def forklift
  4 F   f    forklift          lib/forklift/transports/csv.rb
               class:Forklift.Connection.Csv
               def forklift
  5 F   f    forklift          lib/forklift/transports/elasticsearch.rb
               class:Forklift.Connection.Elasticsearch
               def forklift
  6 F   f    forklift          lib/forklift/transports/mysql.rb
               class:Forklift.Connection.Mysql
               def forklift
Type number and <Enter> (empty cancels):

只用选择一个序号，就直接跳转过去了

跳转

当光标在 generate 时

...
...
if ['--generate', '-generate'].include?(ARGV[0])
  generate
else
  run_plan
end
...
...

使用 Ctrl + ] 可以瞬间跳转到光标所在的函数定义处

...
...
begin
  require 'forklift'
rescue LoadError
  require "#{File.expand_path(File.dirname(__FILE__))}/../lib/forklift.rb"
end

def generate
  p = Dir.pwd

  Dir.mkdir "#{p}/config"
  Dir.mkdir "#{p}/config/connections"
...
...

使用 Ctrl + T 又可以跳回来

文件里定位

在文件里也可以对标记定位

使用 :tag <tag>

比如: 对 forklift 标签进行定位

...
...
  Dir.mkdir "#{p}/template"
  Dir.mkdir "#{p}/transformations"
  Dir.mkdir "#{p}/transports"
:tag forklift

...
...
  Dir.mkdir "#{p}/pid"
  Dir.mkdir "#{p}/template"
  Dir.mkdir "#{p}/transformations"
  Dir.mkdir "#{p}/transports"
  # pri kind tag               file                                                                                 
  1 F   f    forklift          lib/forklift/base/logger.rb
               class:Forklift.Base.Logger
               def forklift
  2 F   f    forklift          lib/forklift/base/mailer.rb
               class:Forklift.Base.Mailer
               def forklift
  3 F   f    forklift          lib/forklift/base/pid.rb
               class:Forklift.Base.Pid
               def forklift
  4 F   f    forklift          lib/forklift/transports/csv.rb
               class:Forklift.Connection.Csv
               def forklift
  5 F   f    forklift          lib/forklift/transports/elasticsearch.rb
               class:Forklift.Connection.Elasticsearch
               def forklift
  6 F   f    forklift          lib/forklift/transports/mysql.rb
               class:Forklift.Connection.Mysql
               def forklift
Type number and <Enter> (empty cancels):

根据左边的数字，就可以快速跳转

相同标签快速跳转

ts tf tl tn tp

在 (ex command) 模式中

Command	Commant
:ts	列出所有当前标签位置
:tf/tfirst	跳转到和当前标签相同的第一个标签位置
:tl/tlast	跳转到和当前标签相同的最后一个标签位置
:[count]tp/[count]tprevious	跳转到和当前标签相同的前N个标签位置
:[count]tn/tnext	跳转到和当前标签相同的后N个标签位置

对于 tp 和 tn 而言，前面加上数字后可以直接跳过指定个数的标签

ts 后
