This would be a very nice and useful tool to have as a SPM plugin. It would feel more like an actual Xcode utility and not a random app.

Not an issue as I worked it out, but I thought others might look here to see how to enable this with the new System Settings app in macOS 13 Ventura.

• Close Xcode & System Settings
• Open the Multiliner app
• Open System Settings
• Go to Privacy & Security
• Scroll down to the end and click Extensions
• Click Xcode Source Editor and make sure Multiliner is toggled on

Now the option appears in the Xcode's Editor menu.

I LOVE this tool and I use it literally everyday when I use Xcode, but I use AppCode a lot as well, and I really really miss it. do you think adding support to AppCode is something that can be done?

Would be nice if it was faster on large files.

Currently, when using Multiliner to multi-line selection, the caret moves to the end of the file. When undoing, the whole file text is selected.

It would be great if the caret stays after the closing bracket of the formatted code.

I love this extension. Thank you for amazing work!

I've followed your instructions, however it does not seem to show up under Extensions on macOS 12.4

I'd love to have a second command that can do the opposite of Multiliner - reformat a multi-line call into a single line.

Background: Our company style guide says if a function call is under 120 chars it should be a single line, otherwise split up like Multiliner does. Often times when refactoring I'm deleting a bunch of parameters and the call would fit on a single line. I'd love a command to be able to reformat it quickly onto one line to check if it fits.

PS: This is incredible, I've been periodically searching for something like this for ages. Thank you so much for making it! You are going to save me a few minutes every day.

Currently when you select a chunk of code that contains parameters nested inside, formatting is weird:

This is because Multiliner splits parameters by commas , — this includes commas inside nested inits.

Possibly a split using Regex?

Played around with Multiliner a bit :)

Given this input:

func applyContentActions(action: AppAction, reducers: [TableActionReducer]) -> (_ documentState: DocumentState) -> DocumentState {
    ...
}

I expected somewhat along these lines::

func applyContentActions(
    action: AppAction,
    reducers: [TableActionReducer]
) -> (_ documentState: DocumentState) -> DocumentState {
    ...
}

Actual output did try to put the parens and the arrow onto a new line, but not the first occurrence:

func applyContentActions(
    action: AppAction,
    reducers: [TableActionReducer]) -> (_ documentState: DocumentState
) -> DocumentState {
    ...
}

Adding the keyboard shortcut via System Preferences has the downsides of being specific to each Xcode version (it seems to list every Xcode version I have installed, although I've not verified if they're all applied separately) and also requiring the exact name of the menu item.

Xcode's Preferences => Key Bindings includes the action from the menu and seems to avoid these issues, so it might be easier to direct users to using this option?

Despite having Multiliner (1.1.0) installed, it simply won't show up in System Settings -> Extensions. I've uninstalled, re-installed, restarted, etc. I'm running macOS 12.5 with Xcode 13.3.1.

It would be nice to have an ability to install app using brew instead of having to do it manually.
What do you think?

p.s. awesome idea for an extension 🎉

That would be much better to add preferences for this utility

The most important one, as for me, to add the maximum allowed line length (e.g. 120)

If the line of code is shorter, there is no need to wrap it around and create multiple lines

With this feature, it would be possible to format the whole file, not only the selected few lines

I have installed the extension, and it doesn't appear in the Xcode menu editor.

I'm using Xcode 13.1, and I also have installed Xcode 13.3

I've tried several things such as the ones described here:

• https://stackoverflow.com/a/67679577/3708095
• nicklockwood/SwiftFormat#494
• https://stackoverflow.com/a/58616132/3708095

But nothing worked, maybe it has something to do with:

While I am actually a fan of Multiliner's current formatting behavior, some people might prefer not having a line-break between the method name and the first parameter.

Current Behavior

func sendAppStatus(
    to toNodes: [Node],
    name: String?,
    bundleID: String,
    state: Int32,
    isDockApp: Bool
) {
    // ...
}

Proposed opt-in behavior (as a preference)

First parameter starts on the same line, and closing parens trails immediately after the last parameter.

func sendAppStatus(to toNodes: [Node],
                   name: String?,
                   bundleID: String,
                   state: Int32,
                   isDockApp: Bool) {
    // ...
}

If I indent with spaces:

result is OK:

But when tabs are used:

result is just a mess of tabs and spaces (which is never correct):

I just noticed that the GitHub docs / App Built-In Docs are out of sync.

• GitHub README shows setting up a Key Binding in Xcode,
• built-in docs of the MultilinerExtension app shows setting up an App Shortcut in System Preferences

Cheers, and thanks for your hard work

While it works perfectly on a one line function, if you already have code like this:

func foobar(_ foo: Foo,
                       bar: Bar)

and you apply multiliner, the result will be:

func foobar(
        _ foo: Foo,

                       bar: Bar
    )

which is not great. It would be awesome if it already detected new lines, and didn't apply new indentation. For the latter I don't know if it could re-use Xcode's reindent command for each line maybe, so you don't have to implement it yourself.

I had v1.0 installed and working, however since installing v1.1 the Xcode Source Editor section of the System->Extensions has disappeared, as if there are no extensions.

I've tried reinstalling v1.0 and it's the same 🤷‍♂️

Is there an additional step needed?

I just saw this:

It'd be cool, if you could only place the cursor in a scope and then it figures out the smallest matching scope that can apply?
