Duplicate Code Finder
Introduction
In fact the tool does not know about code but text. Following options are available:
- (m)inimum(B)lockSize: When duplicate code/test has been found it has to be greater or equal to those configured size otherwise it will be ignored. (default: 4)
- (i)gnore(C)ase: when true then the letter case is ignored (default: false)
- (i)gnore(W)hitespaces: when true then spaces and tabs are ignored (default: false)
- (p)ercentage(S)imilarity: control how many characters have to match (in percentage)
The next table should give a few simple examples on line comparisons:
| First String | Second String | Adjusted Policies | Result |
|---|---|---|---|
| wonderful day | wonderful day | equal | |
| wonderful DAY | wonderful day | not equal | |
| wonderful DAY | wonderful day | iC=true | equal |
| wonderful DAY | wo nd erful d ay | iC=true | not equal |
| wonderful DAY | wo nd erful d ay | iC=true, iW=true | equal |
| Wonderful Day | wonderful day | pS=75 | equal |
| -onderful -ay | wonderful day | pS=75 | equal |
Usage
def listOfSource = xfind.files('.', '*.groovy')
xdup(listOfSources, minimumBlockSize:6, ignoreCase:true,
ignoreWhitespaces:true, percentageSimilarity:90)
Please note: In a declarative pipeline you have to place it in a script { ... } block.
