| 2 | # Make sure fzf uses fish to execute preview commands, some of which |
| 3 | # are autoloaded fish functions so don't exist in other shells. |
| 4 | # Use --function so that it doesn't clobber SHELL outside this function. |
| 5 | set -f --export SHELL (command --search fish) |

| 7 | # If FZF_DEFAULT_OPTS is not set, then set some sane defaults. |
| 8 | # See https://github.com/junegunn/fzf#environment-variables |

| 10 | # cycle allows jumping between the first and last results, making scrolling faster |
| 11 | # layout=reverse lists results top to bottom, mimicking the familiar layouts of git log, history, and env |
| 12 | # border shows where the fzf window begins and ends |
| 13 | # height=90% leaves space to see the current command and some scrollback, maintaining context of work |
| 14 | # preview-window=wrap wraps long lines in the preview window, making reading easier |
| 15 | # marker=* makes the multi-select marker more distinguishable from the pointer (since both default to >) |
