+# mkshrc notes
+
+Checked `mkshrc` with:
+
+```sh
+mksh -n mkshrc
+```
+
+Syntax check passes, but these issues/suspicious spots were found.
+
+## Issues
+
+1. **Mason PATH bug**
+
+   ```sh
+   test -d $HOME/.local/share/nvim/mason/bin && export PATH=$HOME/.local/share/mason/bin:$PATH
+   ```
+
+   The test checks `~/.local/share/nvim/mason/bin`, but the exported path is `~/.local/share/mason/bin`.
+   On this machine the checked directory exists and the exported directory does not.
+
+   Suggested fix:
+
+   ```sh
+   test -d "$HOME/.local/share/nvim/mason/bin" && export PATH="$HOME/.local/share/nvim/mason/bin:$PATH"
+   ```
+
+2. **`stty` / `bind` emit errors without a tty**
+
+   Non-interactive sourcing produced errors like:
+
+   ```text
+   stty: standard input: Not a tty
+   mksh: ./mkshrc[12]: bind: can't bind, not a tty
+   ```
+
+   Suggested guard:
+
+   ```sh
+   [[ -t 0 ]] && stty -ixon
+   [[ -o interactive ]] && {
+     bind '^l'=clear-screen
+     bind '^k'=kill-line
+     bind '^j'=kill-to-eol
+     bind '^e'=edit-line
+   }
+   ```
+
+3. **`HISTFILESIZE` and `HISTCONTROL` are bash-style**
+
+   ```sh
+   export HISTFILESIZE=10000
+   export HISTCONTROL=ignoredups
+   ```
+
+   These are likely ignored by mksh. mksh generally uses `HISTSIZE`/`HISTFILE`; `HISTCONTROL=ignoredups` is not a mksh feature.
+
+4. **`LESSHISTFILE` is set multiple times**
+
+   ```sh
+   export SHELL=$MKSH MANWIDTH=80 LESSHISTFILE=-
+   export LESSHISTFILE=$HOME/.cache/lesshist
+   export LESSHISTFILE="$XDG_STATE_HOME"/less/history
+   ```
+
+   Final value wins. Also `~/.local/state/less` does not currently exist, so less may fail to write history unless created.
+
+5. **`W3M_DIR` contains literal `~`**
+
+   ```sh
+   export W3M_DIR="~/.cache/w3m"
+   ```
+
+   Because `~` is quoted, it will not expand.
+
+   Suggested fix:
+
+   ```sh
+   export W3M_DIR="$HOME/.cache/w3m"
+   ```
+
+6. **`dkr()` has a bug with multiple args**
+
+   ```sh
+   [ -z "$@" ] && cmd="echo"
+   ```
+
+   With multiple arguments this can error in mksh. Use:
+
+   ```sh
+   (( $# == 0 )) && cmd="echo"
+   ```
+
+   Also:
+
+   ```sh
+   cmd="docker $@"
+   ```
+
+   loses argument quoting and can behave badly with spaces/shell metacharacters.
+
+7. **`loop()` should quote args**
+
+   Current:
+
+   ```sh
+   loop() { while true ; do $@; sleep 1; done ;}
+   ```
+
+   Safer:
+
+   ```sh
+   loop() { while true; do "$@"; sleep 1; done; }
+   ```
+
+8. **ANSI gray fallback is probably wrong**
+
+   ```sh
+   txtgry="$(tput setaf 8 2>/dev/null || echo '\e[0;38m')"
+   ```
+
+   `38` normally expects extended color parameters. Better fallback:
+
+   ```sh
+   echo '\e[0;90m'
+   ```
+
+9. **PATH grows on repeated sourcing**
+
+   Re-sourcing this file repeatedly prepends/appends duplicate PATH entries. Not fatal, but noticeable.
+
+10. **Dangerous aliases**
+
+    These may be intentional, but are worth noting:
+
+    ```sh
+    alias cp='cp -r'
+    alias rm='rm -r'
+    alias docker='doas docker'
+    ```
+
+    `rm -r` by default can make accidents worse.
+
+## Most important fixes
+
+- Fix Mason path line.
+- Fix `W3M_DIR`.
+- Fix `dkr()` argument check/quoting.
+- Guard `stty`/`bind` for non-tty/non-interactive use.
