How to compare codes with knime?

[natanzi]

Dear Knimer,

I want to upgrade a software component and it needs to compare more than 1000 separate files.
( compare old version and new version files )
It would be possible to compare one by one with the notepad ++ compare extension, while I would like to automate this process by knime flow. Is there any idea to run it?

Note:
Most of the codes has 99% similarity, And just I want to find out the differentiate between files.

Hi natanzi,

yes, if you got a , everything might look like a nail, but why not try this with a more appropriate tool? I would just add this as two commits to a blank Git repo and get the diff (optionally ignoring whitespaces changes if needed).

git init
# add old files here
git add -A && git commit -m "old version"
# add changed files here
git add -A && git commit -m "new version"
git diff HEAD~1

And if you really want to get back to the hammer, there’s even some Git nodes for KNIME:

Git — NodePit

Fingers crossed!

In case you’re not really into Git, this topic came up two months ago as well and some suggestions were mentioned there.

Text file compare like Notepad++

I would like to compare two “same” program code. I would need a solution similar to Notepad++'s “Compare” solution. The “Table Difference Finder” (TDF) provides a partial solution. Because I need to search for line pairs (e.g. I insert a new line in the compared program code) - TDF does not track it. Thanks in advance.
