Count the number of #defines in a .c file using VBS - scripting

Question

I need to count the number of #define lines in C files (3 of them) using VBS. Please suggest the best way to accomplish this.

Answer 1

The script below uses a regular expression to count the #define statements that appear at the beginning of the lines. Whitespace is allowed before the statement as well as between # and define. The list of files to search in should be passed in as arguments, e.g.:
cscript.exe script_name.vbs c:\myfile1.c c:\myfile2.c
Here's the script code:
Const ForReading = 1
Set oFSO = CreateObject("Scripting.FileSystemObject")
Set re = New RegExp
re.Pattern = "^\s*#\s*define\b"
re.IgnoreCase = False
re.Global = True
re.Multiline = True
strReport = ""
For Each strFileName in WScript.Arguments.Unnamed
Set oFile = oFSO.OpenTextFile(strFileName, ForReading)
strText = oFile.ReadAll
oFile.Close
intCount = re.Execute(strText).Count
strReport = strReport & "There are " & intCount & " #define statement(s) in " & strFileName & vbNewLine
Next
WScript.Echo strReport
The script output is like:
There are 7 #define statement(s) in c:\myfile1.c
There are 0 #define statement(s) in c:\myfile2.c

How about something like this? just pass the files in as arguments
Const token = "#define"
Set objArgs = WScript.Arguments
tokenCount = 0
Set fso = CreateObject("Scripting.FileSystemObject")
For i = 0 To objArgs.Count - 1
Set objFile = fso.OpenTextFile(objArgs(i), 1)
Do Until objFile.AtEndofStream
lineCount = lineCount + 1
If InStr(1, objFile.ReadLine, token, 1) 0 Then
tokenCount = tokenCount + 1
End If
Loop
Next
WScript.echo tokenCount
This will ignore blank spaces between # and define
Const token = "#define"
Set objArgs = WScript.Arguments
tokenCount = 0
Set fso = CreateObject("Scripting.FileSystemObject")
For i = 0 To objArgs.Count - 1
Set objFile = fso.OpenTextFile(objArgs(i), 1)
Do Until objFile.AtEndofStream
lineCount = lineCount + 1
If InStr(1, Replace(objFile.ReadLine, " ", "", 1, -1, 1), token, 1) 0 Then
tokenCount = tokenCount + 1
End If
Loop
Next
WScript.echo tokenCount

This code should count all #define statements in any number of input files. Provisions have been made for whitespace in the statements, such as "# define" or "# define" both of which are valid statements.
NOTE: I do not count for the # on one line and the "define" on the next, I'm assuming the # and "define" are at least on the same line, though you could do so by reading the entire file and removing all whitespace, then save to a variable or temp file or something like that and use that as your input.
You can shorten the code a bunch by ditching the file access constants and what not, otherwise it will give you output like this:
There are: 9 define statements in the source: c:\define.txt
There are: 11 define statements in the source: c:\define2.txt
There are: 10 define statements in the source: c:\define3.txt
The command line would be: cscript scriptname.vbs c:\define.txt c:\define3.txt etc...
' Define constants for file access
Const TristateFalse = 0
Const ForReading = 1
Const ForWriting = 2
Const ForAppending = 8
Set objFSO = CreateObject("Scripting.FileSystemObject")
Set objArgs = WScript.Arguments
If objArgs.Count > 0 then
For i = 0 To objArgs.Count - 1
Set objFileInputStream = objFSO.OpenTextFile(objArgs(i), ForReading, False, TristateFalse)
intTempCount = 0
tokenCount = 0
Do while not objFileInputStream.AtEndOfStream
strLine = replace(ucase(objFileInputStream.ReadLine), " ", "")
intLineLength = len(strLine)
Do
If instr(strLine, "#DEFINE") <> 0 then
tokenCount = tokenCount + 1
strLine = replace(strLine, "#DEFINE","", 1, 1)
intTempCount = intTempCount + 1
else
exit do
End If
Loop until intTempCount = intLineLength
Loop
objFileInputStream.Close
wscript.echo "There are: " & tokenCount & " define statements in the source: " & objArgs(i)
Next
Else
wscript.echo "You must enter at least one filename."
End If

I'm not that good at VB script, but something like ...
Dim re as New RegExp
re.IgnoreCase = True
re.Global = True
re.Pattern = "#define"
Set mc = re.Execute(yourFileText)
ans = mc.Count
