Test 5 with MacOS's built in echo

Index	Platform	Test	Result
13	MacOS	^echo '**/*.json'	**/*.json
14	MacOS	^echo "**/*.json"	**/*.json
15	MacOS	^echo `**/*.json`	.vscode/settings.json crates/nu-command/assets/228_themes.json samples/wasm/package-lock.json samples/wasm/package.json target/.rustc_info.json and all the other json files
16	MacOS	^echo **/*.json	.vscode/settings.json crates/nu-command/assets/228_themes.json samples/wasm/package-lock.json samples/wasm/package.json target/.rustc_info.json and all the other json files

Test 6 quote argument with spaces

Index	Platform	Test	Result
17	MacOS	^echo "–name='xx' –value='yy'"	–name='xx' –value='yy'
18	MacOS	^echo '–name="xx" –value="yy"'	–name="xx" –value="yy"
19	Windows	^echo "–name='xx' –value='yy'"	"–name='xx' –value='yy'" (failure)
20	Windows	^echo '–name="xx" –value="yy"'	'–name="xx" –value="yy"' (failure)

But if the argument is defined as a variable, we don't need to quote them.

let argument = "--name='xx' --value='yy'"

Index	Platform	Test	Result
21	MacOS	^echo $argument	–name='xx' –value='yy'
22	Windows	^echo $argument	–name='xx' –value='yy'

Index	Platform	Test	Result
23	MacOS	^echo '–aa="bbbb"'	–aa="bbbb"
24	MacOS	^echo "–aa='bbbb'"	–aa='bbbb'
25	MacOS	^echo –aa="bbbb"	–aa="bbbb"
26	Windows	^echo '–aa="bbbb"'	–aa=\bbbb" (failure)
27	Windows	^echo "–aa='bbbb'"	–aa=bbbb (failure)
28	Windows	^echo –aa="bbbb"	–aa=bbbb (failure)

Test 7 - fzf with list of parameters

Setup

let-env FZF_DEFAULT_OPTS = '--cycle --layout=reverse --border --height=90% --preview-window=wrap --marker="*"'

let log_fmt_str = '%C(bold blue)%h%C(reset) - %C(cyan)%ad%C(reset) %C(yellow)%d%C(reset) %C(normal)%s%C(reset)  %C(dim normal)[%an]%C(reset)'

Test 7.1 (preview with git show)

let selected_log_lines = (
git log [--format=format:($log_fmt_str) --date=short --color=always] |
fzf [--ansi --multi --tiebreak=index --preview='git show --color=always --stat --patch {1}']
)

Result 7.1

• Windows - Fails
• MacOs - Fails

Test 7.2 (preview with git show - change quoting)

let selected_log_lines = (
git log [--format=format:($log_fmt_str) --date=short --color=always] |
fzf [--ansi --multi --tiebreak=index  "--preview=git show --color=always --stat --patch {1}"]
)

Result 7.2

• Windows - Succeeds
• MacOs - Succeeds

Test 7.3 (preview with git show - remove list syntax)

let selected_log_lines = (
git log [--format=format:($log_fmt_str) --date=short --color=always] |
fzf --ansi --multi --tiebreak=index  --preview='git show --color=always --stat --patch {1}'
)

Result 7.3

• Windows - Succeeds
• MacOs - Succeeds
