Get total lines of files

View Post

This is one small tools to get the total file line number of on folder.

POST_FIX = %w{java jsp html xml properties}
2

EXCLUDE_DIR = %w{CVS}
3

$displayStr = ""
4

$fileReg = ""
5

$dirReg = "\\.|\\.\\.|"
6

def sumLine(fileName)
8

file = open fileName
9

begin
10

while file.gets()
11

end
12

ensure
13

file.close
14

end
15

$.
16

end
17

def iteDir(name, level=0)
19

lines = 0
20

dir = Dir.open name
21

rex = /\. + "java" +$|\.jsp$|\.html$/
22

begin
23

dir.each do |fileName|
24

fileName = dir.path + '/' + fileName
25

if File.ftype(fileName) =~ /directory/
26

if not fileName =~ Regexp.new($dirReg)
27

lines += iteDir(fileName, level+1)
28

else
29

next
30

end
31

elsif fileName =~ Regexp.new($fileReg)
32

lines += sumLine(fileName)
33

end
34

end
35

ensure
36

dir.close
37

end
38

str = ""
39

for i in 0..(level-1)
40

str += "\t|"
41

end
42

if level != 0
43

str += "---"
44

end
45

$displayStr = "#{str}#{name}\t#{lines} lines\n#{$displayStr}"
46

lines
47

end
48

POST_FIX.each do |postfix|
50

$fileReg += "\.#{postfix}$|"
51

end
52

$fileReg = $fileReg.chop
53

EXCLUDE_DIR.each do |excludeDir|
55

$dirReg += "^#{excludeDir}$|"
56

end
57

$dirReg = $dirReg.chop
58

print "Total #{iteDir("E:/_MyWorkSpace/IDEA_Proj")} lines\n"
60

print $displayStr

Keystone:
   1. Ruby I/O access. Dir and File
   2. Regexp & String -> Regexp
   3. Some kinds of variables
   4. Array operation

reinventing the wheel:
+ require 'find'
+ IO.readlines(path).size

inefficient:
+ append to arrays, not strings ( a = []; a << ...; a.join )
+ don't create a million regexp objects in a tight loop when one will do ($fileReg = /#{...}/; fileName =~ $fileReg)
