The following comment was made by an LLM, it may be inaccurate: Potential Duplicate FoundPR #20934: feat: buffer stdin during TUI startup so early input is preserved Why it's related: PR #24412 explicitly mentions that it "takes a different approach to #20934". Both PRs address the same issue (#14415) - preventing characters from being dropped while typing between launching opencode and the prompt UI being rendered. The main difference is that PR #24412 leverages OpenTUI's StdinParser instead of custom parsing logic. Additional related PR: This is also stdin-related but appears to address cleanup rather than input buffering during startup. |

Closes #14415
Type of change
What does this PR do?
This addresses chars being dropped while typing between launching opencode and the prompt UI being rendered, by buffering stdin and seeding the prompt state with it later.
This takes a different approach to #20934, leveraging OpenTUI's StdinParser rather than parsing the input ourselves.
I attempted to address @TZubiri's concern, but couldn't find a subtractive solution that worked. That said, I'm not well versed in OpenTUI. It seems to take stdin ownership and set it to raw mode immediately in
createCliRenderer(). I tried in a small repro project that delays before rendering a text box, and input was swallowed there too.How did you verify your code works?
