The Chez jsh port exports `jsh-init!`, `jsh-capture`. Aliases are provided in `jsh/lib.sls`: + +```scheme +(define gsh-init! jsh-init!) +(define gsh-capture jsh-capture) +``` + +## Common Issues + +### test-functional fails: `string-prefix?` unbound + +Fix: ensure `(only (std srfi srfi-13) string-contains string-prefix?)` is in imports. + +### Tests fail: `run-time information for library (jsh ...) not loaded` + +Fix: rebuild jsh: `cd ~/mine/jerboa-shell && make jsh-compile` + +### shell-start! or gsh-capture hangs + +Root cause: The user's `~/.jshrc` (symlinked to `~/.gshrc`) contains command substitutions like `$(tput setaf 33)`. These call `command-substitute` which uses `open-output-file "/dev/fd/1"` — this acquires a Chez port registry lock that deadlocks with the Chez scheduler when called from a secondary thread. + +In tests, use `jsh-init!` (non-interactive, no startup files) instead of `shell-start!`: + +```scheme +(define (make-test-shell!) + (let ((env (jsh-init!))) ;; non-interactive: no ~/.jshrc sourced + (env-set! env "SHELL" "gsh") + (make-shell-state env 0 #f #f #f #f #f #f))) +``` + +For production shell use, `run-process-interruptible` (in `subprocess.ss`) is the safe alternative that doesn't use `command-substitute`. + +### git-output or cmd-show-git-log hangs + +Root cause: old code used `open-process` (Gerbil compat shim) which creates a port with a blocking `read-proc`. Fixed in `editor-extra-tools.ss` and `editor-cmds-b.ss` to use `open-process-ports` directly. + +### jsh *gsh-tier* unbound + +Fix: `jsh/registry.sls` exports `*jsh-tier*` (not `*gsh-tier*`).
