19 The Ruby interface only works when Vim was compiled with the |+ruby| feature.
|
|
|
20
|
|
|
21 The home page for ruby is http://www.ruby-lang.org/. You can find links for
|
|
|
22 downloading Ruby there.

|
|
|
25 1. Commands *ruby-commands*
|
|
|
26
|
|
|
27 *:ruby* *:rub*
|
|
|
28 :rub[y] {cmd} Execute Ruby command {cmd}.
|
|
|
29
|
|
|
30 :rub[y] << {endpattern}
|
|
|
31 {script}
|
|
|
32 {endpattern}
|
|
|
33 Execute Ruby script {script}.
|
|
|
34 {endpattern} must NOT be preceded by any white space.
|
|
|
35 If {endpattern} is omitted, it defaults to a dot '.'
|
|
236
|
36 like for the |:append| and |:insert| commands. This
|
|
7
|
37 form of the |:ruby| command is mainly useful for
|
|
|
38 including ruby code in vim scripts.
|
|
|
39 Note: This command doesn't work when the Ruby feature
|
|
|
40 wasn't compiled in. To avoid errors, see
|
|
|
41 |script-here|.
|
|
|
42
|
|
|
43 Example Vim script: >
|
|
|
44
|
|
|
45 function! RedGem()
|
|
|
46 ruby << EOF
|
|
|
47 class Garnet
|
|
|
48 def initialize(s)
|
|
|
49 @buffer = VIM::Buffer.current
|
|
|
50 vimputs(s)
|
|
|
51 end
|
|
|
52 def vimputs(s)
|
|
|
53 @buffer.append(@buffer.count,s)
|
|
|
54 end
|
|
|
55 end
|
|
|
56 gem = Garnet.new("pretty")
|
|
|
57 EOF
|
|
|
58 endfunction
|
|
|
59 <
|
|
|
60
|
|
|
61 *:rubydo* *:rubyd* *E265*
|
|
|
62 :[range]rubyd[o] {cmd} Evaluate Ruby command {cmd} for each line in the
|
|
|
63 [range], with $_ being set to the text of each line in
|
|
236
|
64 turn, without a trailing <EOL>. Setting $_ will change
|
|
7
|
65 the text, but note that it is not possible to add or
|
|
|
66 delete lines using this command.
|
|
|
67 The default for [range] is the whole file: "1,$".
|
|
|
68
|
|
|
69 *:rubyfile* *:rubyf*
|
|
|
70 :rubyf[ile] {file} Execute the Ruby script in {file}. This is the same as
|
|
|
71 ":ruby load 'file'", but allows file name completion.
|
|
|
72
|
|
|
73 Executing Ruby commands is not possible in the |sandbox|.

|
76 2. The VIM module *ruby-vim*
|
|
|
77
|
|
|
78 Ruby code gets all of its access to vim via the "VIM" module.
|
|
|
79
|
|
|
80 Overview >
|
|
809
|
81 print "Hello" # displays a message
|
|
|
82 VIM.command(cmd) # execute an ex command
|
|
|
83 num = VIM::Window.count # gets the number of windows
|
|
|
84 w = VIM::Window[n] # gets window "n"
|
|
|
85 cw = VIM::Window.current # gets the current window
|
|
|
86 num = VIM::Buffer.count # gets the number of buffers
|
|
|
87 b = VIM::Buffer[n] # gets buffer "n"
|
|
|
88 cb = VIM::Buffer.current # gets the current buffer
|
|
|
89 w.height = lines # sets the window height
|
|
|
90 w.cursor = [row, col] # sets the window cursor position
|
|
|
91 pos = w.cursor # gets an array [row, col]
|
|
|
92 name = b.name # gets the buffer file name
|
|
|
93 line = b[n] # gets a line from the buffer
|
|
|
94 num = b.count # gets the number of lines
|
|
|
95 b[n] = str # sets a line in the buffer
|
|
|
96 b.delete(n) # deletes a line
|
|
|
97 b.append(n, str) # appends a line after n
|
|
|
98 line = VIM::Buffer.current.line # gets the current line
|
|
|
99 num = VIM::Buffer.current.line_number # gets the current line number
|
|
|
100 VIM::Buffer.current.line = "test" # sets the current line number

157 4. VIM::Window objects *ruby-window*
|
|
|
158
|
|
|
159 VIM::Window objects represent vim windows.
|
|
|
160
|
|
|
161 Class Methods:
|
|
|
162
|
|

168 Methods:
|
|
|
169
|

|
|
|
178
|
|
|
179 ==============================================================================
|
|
557
|
180 5. Global variables *ruby-globals*
|
|
7
|
181
|
|
|
182 There are two global variables.
|
|
|
183
|
|
|
184 $curwin The current window object.
|
|
|
185 $curbuf The current buffer object.
|
|
|
186
|
|
|
187 ==============================================================================
|
|
557
|
188 6. Dynamic loading *ruby-dynamic*
|
|
|
189
|
|
|
190 On MS-Windows the Ruby library can be loaded dynamically. The |:version|
|
|
|
191 output then includes |+ruby/dyn|.
|
|
|
192
|
|
|
193 This means that Vim will search for the Ruby DLL file only when needed. When
|
|
|
194 you don't use the Ruby interface you don't need it, thus you can use Vim
|
|
|
195 without this DLL file.
|
|
|
196
|
|
|
197 To use the Ruby interface the Ruby DLL must be in your search path. In a
|
|
|
198 console window type "path" to see what directories are used.
|
|
|
199
|
|
|
200 The name of the DLL must match the Ruby version Vim was compiled with.
|
|
|
201 Currently the name is "ruby18.dll". That is for Ruby 1.8. To know for sure
|
|
|
202 edit "gvim.exe" and search for "ruby\d*.dll\c".
