Subshell support has been added to Warp, allowing users to "Warpify" their bash, zsh, or fish subshells and access core features even when working in a nested session. This includes modern IDE-style output, blocks, autocompletions, workflows, AI Command Search, and more. Warp now recognizes certain commands as "subshell-compatible" and prompts users to Warpify them. Users can also add custom bash/zsh/fish commands for Warpification or blocklist specific commands from being Warpified. This feature is highly requested and beneficial for developers working with subshells in their workflows.
