TUI shows LaTeX math in messages as raw source #53648
Description
Description
Models often write math in prose as \( … \), \[ … \] or $$ … $$. The current TUI passes message text straight to the opentui <markdown> component, which has no math support, so the formulas show as raw LaTeX. For example \(0.5^5 \approx 3\%\) instead of 0.5⁵ ≈ 3%, or \text{saved} = (\text{units …}) \times \text{rate}.
#40508 tracks native LaTeX rendering for the v2 TUI. This is about the v1 TUI on dev.
Plugins

Steps to reproduce

- The answer shows
\(\frac\approxand so on as plain text

Thanks for the clear report and the screenshot, @moritzWa!
This is about the v1 TUI (1.18.34 /
dev). v1 only gets fixes for critical bugs, such as data loss, security problems, or crashes and breakage with no workaround. Raw LaTeX in messages is a rendering feature rather than a critical bug, so it's unlikely to be fixed in v1.LaTeX rendering for the v2 TUI (
@opencode/cli,opencode2) is tracked in #40508, which you already linked. We'd encourage upgrading to v2 and following that issue.If you think this is critical, or you see something different on v2 that isn't covered by #40508, please reply here.

This issue might be a duplicate of existing issues. Please check:

We aren't going to backport many features to v1 most likely, Im giing to close in favor of the existing latex issue even tho this one is targeted at v1 instead.
We will do LaTeX soon.

Closing as not planned. Raw LaTeX in messages in the v1 TUI (1.18.34 /
dev) isn't a critical bug, and v1 only gets critical fixes. We waited a few days in case this turned out to be critical or also happened on v2, and haven't heard back.LaTeX rendering for the v2 TUI is tracked in #40508, so please follow that issue. If you see this on v2 in a way #40508 doesn't cover, feel free to open a new issue. Thanks for the report, @moritzWa!
