This affects developers working in split windows or terminals with limited width. + +## Running the Reproducer + +The reproducer is contained in a single Nix flake that includes everything needed: +- Neovim with overseer.nvim configured +- A C++ test file with intentional compilation errors that generate long messages +- Automated test script that demonstrates the truncation + +### Quick Run + +```bash +# Run the test directly (from the overseer.nvim directory) +nix run + +# Or from any other directory +nix run /home/tim/src/overseer.nvim + +# Or build and run separately +nix build +./result/bin/test-issue445 +``` + +## What the Test Does + +1. Sets up a Neovim environment with overseer.nvim plugin properly installed +2. Configures the terminal width to 80 columns (narrow) to trigger potential truncation +3.

Overseer's `jobstart` strategy creates a PTY (pseudo-terminal) for running commands +2. By default, the PTY width matches the current Neovim window width +3. Many compilers format their output based on terminal width, truncating long lines +4.
