+# Zsh completion for the `e2e` and `e2e-cli` recipes in lazygit's justfile.
+#
+# These recipes take integration-test names (e.g. submodule/reset). This makes
+# `just e2e <Tab>` complete them from pkg/integration/tests/. To enable it, add
+# the following to your ~/.zshrc, *after* the line that runs `compinit`:
+#
+#     source /path/to/lazygit/scripts/just_e2e_completion.zsh
+#
+# It is a no-op when `just` isn't installed, and only kicks in inside a project
+# that has a justfile and a pkg/integration/tests/ directory, so it is harmless
+# to source unconditionally.
+
+(( $+commands[just] )) || return 0
+
+# just's own completion is clap-dynamic and has no hook for completing a
+# recipe's arguments, so we wrap it: handle the e2e recipes ourselves and
+# delegate everything else (recipe names, flags, ...) to just's completer.
