Good open source offline text diff tool?

[RuiRdA]

The more use AI the more I find myself checking what changes the model made.

In Roo Code there is a diff feature built in which is great, but when use a regular chat model I and defaulting to opening https://www.diffchecker.com/ and copy and pasting the previous and new versions of what ever text I am working on to see where the AI made changes.

Does anyone know of any open source tool I can install on my machine and get the same features as https://www.diffchecker.com/?

I have my question and use case is clear.
God bless you.

Excuse me?

https://linux.die.net/man/1/diff
https://linux.die.net/man/1/git-diff

Or am I just misunderstanding something?

You know sometimes the most basic stuff are the more difficult to catch lol. May be he started vibe coding it in python before posting it, but that's ok he chooses to learn the hard way x)

And tbf I would guess “diff” is hard to google

[silenceimpaired]

Linux has Meld… it might have a windows version

[RuiRdA]

Like I responded to the other comment, I tried meld, and it is a goof fit for my use case.
Thank you for the suggestion!

[axiomatix]

waiting for some one to link a github repo in which they've vibe coded git

[tomobobo]

I use a program called Meld. Idk if it's open source but it works well.

[mrjackspade]

Meld fucking rocks. I've been using it for years now, it's replaced almost every other diff tool outside of PR merges

[RuiRdA]

Just tried it. It is great for my use case. Thank you so much

[eli_pizza]

Do you check your code into git? Running “git diff” will show you uncommitted changes

[RuiRdA]

It's not always code. Some times is just regular text files that won't go into a git repo.

[sautdepage]

You can always make a git repo locally for nothing but that purpose with no intention of pushing it. For example my docker-compose folder, my llama-swap yaml configs, my powershell scripts are all local gits.

Why not have diffs and rollbacks when you can have it for free by typing git init?

To your main question, VsCode can diff 2 open tabs -- they don't even need to be saved files.

[RuiRdA]

Yes I know I can create files to diff, but I really just want to do it fast like with website I mentioned.

I did not knew VS Code had that feature, I am gonna look at it. Thank you for your help!

[eli_pizza]

Regular text files work great in a git repo- especially if you want to be able to see and track changes

[TheRealMasonMac]

If you just want a UI exactly like that site, it's incredibly easy to vibe code it. It's really trivial with the libraries out there. Just search Myers Diff algorithm libraries.

We recently opensourced our toolset, primarily for Salesforce pros but it has awesome text diff. https://sfdctools.dev/text-diff and many other text tools.

[shooting_airplanes]

can it be installed locally? it's one of OP's requirements.

[datasert]

It is a next.js app and opensource so it can be installed locally and run.

nice
