From 8a2fa6485e54483332b6224f04be47c9047f1947 Mon Sep 17 00:00:00 2001 From: Jason Rayne Date: Tue, 24 Jun 2025 17:15:35 -0700 Subject: [PATCH] refactor: extract SSH cache functionality to shared script Addresses feedback about separation of concerns in shell integration scripts. Extracts host caching logic to `src/shell-integration/shared/ghostty-ssh-cache` and updates all four shell integrations to use the shared script. The `shared/` subdirectory preserves the existing organizational pattern where all shell-specific code lives in subdirectories. This cleanly separates SSH transport logic from cache management while reducing code duplication by ~25%. All existing SSH integration behavior remains identical. --- src/shell-integration/bash/ghostty.bash | 65 ++--- .../elvish/lib/ghostty-integration.elv | 233 +++++++----------- .../ghostty-shell-integration.fish | 81 +++--- .../shared/ghostty-ssh-cache | 11 + src/shell-integration/zsh/ghostty-integration | 66 ++--- 5 files changed, 174 insertions(+), 282 deletions(-) create mode 100755 src/shell-integration/shared/ghostty-ssh-cache diff --git a/src/shell-integration/bash/ghostty.bash b/src/shell-integration/bash/ghostty.bash index 6e09ab193..9ba11c845 100644 --- a/src/shell-integration/bash/ghostty.bash +++ b/src/shell-integration/bash/ghostty.bash @@ -97,56 +97,48 @@ fi # SSH Integration if [[ "$GHOSTTY_SHELL_FEATURES" =~ ssh-(env|terminfo) ]];
