**Note:** There is an open issue ([#102](https://github.com/tarruda/zsh-autosuggestions/issues/102)) when using this plugin with `bracketed-paste-magic`, which is enabled by default by Oh My Zsh. See the comments in that issue for a workaround.

### [`zsh-history-substring-search`](https://github.com/zsh-users/zsh-history-substring-search)
When the buffer is empty and one of the `history-substring-search-up/down` widgets is invoked, it will call the `up/down-line-or-history` widget. If the `up/down-line-or-history` widgets are in `ZSH_AUTOSUGGEST_CLEAR_WIDGETS` (the list of widgets that clear the suggestion), this can create an infinite recursion, crashing the shell session.
For best results, you'll want to remove `up-line-or-history` and `down-line-or-history` from `ZSH_AUTOSUGGEST_CLEAR_WIDGETS`:
```
# Remove *-line-or-history widgets from list of widgets that clear the autosuggestion to avoid conflict with history-substring-search-* widgets
ZSH_AUTOSUGGEST_CLEAR_WIDGETS=("${(@)ZSH_AUTOSUGGEST_CLEAR_WIDGETS:#(up|down)-line-or-history}")
```
Additionally, the `history-substring-search-up` and `history-substring-search-down` widgets are not bound by default. You'll probably want to add them to `ZSH_AUTOSUGGEST_CLEAR_WIDGETS` so that the suggestion will be cleared when you start searching through history:
The `history-substring-search-up` and `history-substring-search-down` widgets are not bound by default. You'll probably want to add them to `ZSH_AUTOSUGGEST_CLEAR_WIDGETS` so that the suggestion will be cleared when you start searching through history:
```sh
# Add history-substring-search-* widgets to list of widgets that clear the autosuggestion
ZSH_AUTOSUGGEST_CLEAR_WIDGETS+=(history-substring-search-up history-substring-search-down)
```
For example:
```sh
source ~/.zsh/zsh-autosuggestions/zsh-autosuggestions.zsh
source ~/Code/zsh-history-substring-search/zsh-history-substring-search.zsh
ZSH_AUTOSUGGEST_CLEAR_WIDGETS=("${(@)ZSH_AUTOSUGGEST_CLEAR_WIDGETS:#(up|down)-line-or-history}")
