Xcode source automatic formatting

Question

As a C# developer, I have become highly dependent on the automatic formatting in Visual Studio 2008. Specifically, I will use the CTRL + K , D

Answer 1

You could try that XCode plugin https://github.com/benoitsan/BBUncrustifyPlugin-Xcode

Just clone github repository, open plugin project in XCode and run it. It will be installed automatically. Restart Xode before using formatter plugin.

Don't forget to install uncrustify util before. Homebrew, for exmaple

brew install uncrustify

P.S. You can turn on "after save formatting" feature at Edit > Format Code > BBUncrustifyPlugin Preferences > Format On Save

Hope this will be useful for u ;-)

We can use Xcode Formatter which uses uncrustify to easily format your source code as your team exactly wants to be!.

Installation The recommended way is to clone GitHub project or download it from https://github.com/octo-online/Xcode-formatter and add the CodeFormatter directory in your Xcode project to get : Xcode shortcut-based code formatting: a shortcut to format modified sources in the current workspace automatic code formatting: add a build phase to your project to format current sources when application builds all sources formatting: format all your code with one command line your formatting rules shared by project: edit and use a same configuration file with your project dev team 1) How to setup the code formatter for your project Install uncrustify The simplest way is to use brew: $ brew install uncrustify

To install brew: $ ruby –e “$(curl –fsSkl raw.github.com/mxcl/homebrew/go)”

Check that uncrustify is located in /usr/local/bin $ which uncrustify

If your uncrustify version is lower than 0.60, you might have to install it manually since modern Objective-C syntax has been added recently. Add CodeFormatter directory beside your .xcodeproj file

Check that your Xcode application is named "Xcode" (default name) You can see this name in the Applications/ directory (or your custom Xcode installation directory). Be carefull if you have multiple instances of Xcode on your mac: ensure that project's one is actually named "Xcode"! (Why this ? This name is used to find currently opened Xcode files. See CodeFormatter/Uncrustify_opened_Xcode_sources.workflow appleScript). Install the automator service Uncrustify_opened_Xcode_sources.workflow Copy this file to your ~/Library/Services/ folder (create this folder if needed).Be careful : by double-clicking the .workflow file, you will install it but the file will be removed! Be sure to leave a copy of it for other users.

How to format opened files when building the project Add a build phase "run script" containing the following line:

sh CodeFormatter/scripts/formatOpendSources.sh

How to format files in command line

To format currently opened files, use formatOpenedSources.sh:

$sh CodeFormatter/scripts/formatOpendSources.sh

To format all files, use formatAllSources.sh:

$sh CodeFormatter/scripts/formatAllSources.sh PATH

PATH must be replaced by your sources path.

E:g; if project name is TestApp then the command will be

$sh CodeFormatter/scripts/formatAllSources.sh TestApp

it will look for all files in the project and will format all the files as configured in uncrustify_objective_c.cfg file.

How to change formatter’s rules

Edit CodeFormatter/uncrustify_objective_c.cfg open with TextEdit

Answer 3

Well I was searching for an easy way. And find out on medium.

First to copy the json text and validate it on jsonlint or something similar. Then to copy from jsonlint, already the json is formatted. And paste the code on Xcode with preserving the format, shortcut shift + option + command + v

Answer 4

My personal fav PrettyC wantabe is uncrustify: http://uncrustify.sourceforge.net/. It's got a few billion options however so I also suggest you download UniversalIndentGUI_macx, (also on sourceforge) a GUI someone wrote to help set the options the way you like them.

You can then add this custom user script to uncrustify the selected text:

#! /bin/sh
#
# uncrustify!
echo -n "%%%{PBXSelection}%%%"
/usr/local/bin/uncrustify -q -c /usr/local/share/uncrustify/geo_uncrustify.cfg -l oc+ <&0
echo -n "%%%{PBXSelection}%%%"

Answer 5

Cmd A + Ctrl I

Or Cmd A And then Right Click. Goto Structure -> Re-Indent

Answer 6

I'd like to recommend two options worth considering. Both quite new and evolving.

ClangFormat-Xcode (free) - on each cmd+s file is reformatted to specific style and saved, easy to deploy within team

An Xcode plug-in to format your code using Clang's format tools, by @travisjeffery.

With clang-format you can use Clang to format your code to styles such as LLVM, Google, Chromium, Mozilla, WebKit, or your own configuration.

Objective-Clean (paid, didn't try it yet) - app raising build errors if predefined style rules are violated - possibly quite hard to use within the team, so I didn't try it out.

With very minimal setup, you can get Xcode to use our App to enforce your rules. If you are ever caught violating one of your rules, Xcode will throw a build error and take you right to the offending line.
