Tool apply_patch messes up line endings in windows #37090
Description
Description
Editing files with Opencode messes up line endings in files in Windows.
Per default line endings in Windows are CRLF. However, opencode introduces LF line endings when using the builtin tool apply_patch. As I'am this problem occurs also for tool write.
Afaik a suitable merge request: #20217
This issue is related to #6348 which has been closed automatically. However, it is still a annoying issue.
Besides that I want to thank you for the amazing project!

OpenCode version

Steps to reproduce
- Use an existing code file with CRLF line endings.
- I use GPT 5.4 as model
- Use a suitable prompt such that a code line will be added.
- This new line should have LF endings instead of CRLF.

This issue is still present in 1.18.16 - It is really annoying :(

#45931 might resolve this issue, too

This issue is still a thing in opencode v2 :(

I ran into this issue too, and a number of my AI sessions dragged on unnecessarily while the model was trying to restore CRLF line endings across all the modified files.
FWIW, I’m currently using a plugin to work around the shortcomings of the native OpenCode tool.
The plugin only works for changes made within the OpenCode session working directory.

Hi,
I've solved it with a plugin, too: https://github.com/Mac-Moneysac/opencode-fix-line-endings
It preserves line endings and ensures typical platform line endings for new files. It is available via npm such that one can easily use it via config. It is compatible with V2.
However, I would prefer if opencode fixes this issue.
Thank you for your support☺️ !

Thanks for the report! OpenCode 2.0 is now out and development is focused on V2, so we're closing issues filed against OpenCode 1. Please upgrade (
opencode upgrade --major, details: https://anoma.ly/notes/opencode-2-0), and if this is still relevant on 2.0, reopen this issue or open a new one with your 2.0 version.— from 𝕺𝖕𝖊𝖓𝕮𝖔𝖉𝖊
