What are some good Xcode scripts to speed up development?

Question

Xcode allows you to create automated scripts for performing repetitive tasks. What scripts have you written to speed up development?

Answer 1

Here's one to log a method and its arguments any time it's executed (Select the method definition up through the lie with the opening brace and execute the script). If FIXME shows up in the output it means it's an unrecognized type. You can either add it to the script or choose the proper format specifier manually.

#!/usr/bin/python

# LogMethod
# Selection
# Selection
# Insert after Selection
# Display in Alert

import sys
import re

input = sys.stdin.read()

methodPieces = re.findall("""(\w*:)""", input)
vars = re.findall(""":\(([^)]*)\)[ ]?(\w*)""", input)

outputStrings = ["\n  NSLog(@\""]

# Method taking no parameters
if not methodPieces:
    outputStrings.append(re.findall("""(\w*)[ ]?{""", input)[0])

for (methodPiece, var) in zip(methodPieces, vars):
    type = var[0]
    outputStrings.append(methodPiece)
    if "**" in type:
        outputStrings.append("%p")
    elif "*" in type:
        if "char" in type:
            outputStrings.append("%c")
        else:
            outputStrings.append("%@")
    else:
        if "int" in type or "NSInteger" in type or "BOOL" in type:
            outputStrings.append("%i")
        elif "NSUInteger" in type:
            outputStrings.append("%u")
        elif "id" in type:
            outputStrings.append("%@")
        elif "NSTimeInterval" in type:
            outputStrings.append("%f")
        elif "SEL" in type:
            outputString.append("%s")
        else:
            outputStrings.append('"FIXME"')
    if not methodPiece == methodPieces[-1]:
        outputStrings.append('\\n"\n         @"')

outputStrings.append("\"")

for var in vars:
    name = var[1]
    outputStrings.append(",\n         ")
    outputStrings.append(name)

outputStrings.append(");")

print "".join(outputStrings),

Answer 2

Here's one to create a -description method for a class. Highlight the instance variables declaration section (@interface ... { ... }) and execute the script. Then paste the result into your implementation. I use this one along with po objectName in GDB. If FIXME shows up in the output it means it's an unrecognized type. You can either add it to the script or choose the proper format specifier manually.

#!/usr/bin/python

# Create description method for class
# Selection
# Selection
# Insert after Selection
# Display in Alert

import sys
import re

input = sys.stdin.read()

className = re.findall("""(?:@interface )(\w*)""", input)[0]
vars = re.findall("""(\w*[ ][*]?)(\w*?)_?;""", input)

outputStrings = ["- (NSString *)description {\n"]
outputStrings.append("""return [NSString stringWithFormat:@"%s :\\n"\n@"  -""" % className)

for type, var in vars:
    outputStrings.append("%s:" % var)
    if "**" in type:
        outputStrings.append("%p")
    elif "*" in type:
        if "char" in type:
            outputStrings.append("%c")
        else:
            outputStrings.append("%@")
    else:
        if "int" in type or "NSInteger" in type or "BOOL" in type:
            outputStrings.append("%i")
        elif "NSUInteger" in type:
            outputStrings.append("%u")
        elif "id" in type:
            outputStrings.append("%@")
        elif "NSTimeInterval" in type:
            outputStrings.append("%f")
        elif "SEL" in type:
            outputString.append("%s")
        else:
            outputStrings.append('"FIXME"')

    if not var == vars[-1][1]:
        outputStrings.append(',\\n"\n@"  -')

outputStrings.append("\"")

for type, var in vars:
    outputStrings.append(",\n")
    outputStrings.append("[self %s]" % var)

outputStrings.append("];\n}")

print "".join(outputStrings),

Answer 3

Here's one that I found somewhere else that creates @property (copy) and @synthesize property directives for an instance variable. It could use a bit of improvement (say, to let you synthesize multiple variables at once), but it's better than creating them by hand.

Select the instance variable you want to create a property for and activate the script.

If I want a (retain) instead of (copy) I just activate the script and change it to retain manually (it's smart enough to not include the (copy) on primitive types such as int to begin with).

Answer 4

I've created three for my JSON.Framework for Cocoa and the iPhone. These take care of the following:

• Creates a release Disk Image with dynamic embedded Framework, custom iPhone SDK, API documentation and some documentation files in.
• Run Doxygen over the source to create an Xcode-compatible documentation set and install this. This means when you search for things in Xcode's documentation search your documentation can be found too.
• Run Doxygen over the source to update a checked-in version of the API documentation in the source tree itself. This is pretty neat if you use Subversion (which it assumes) as the documentation is always up-to-date for the branch you're in. Great if you're hosting on Google Code, for example.

Beware some hard-coded project-specific values in the below. I didn't want to potentially break the scripts by editing those out. These are launched from a Custom Script Phase in Xcode. You can see how they're integrated in the Xcode project for the project linked above.

Answer 5

This is an improvement of the "Create Property and Synths for instance variables" script that Lawrence Johnston posted above.

Settings:

Input: Entire Document Directory: Home Directory Output: Discard Output Errors: Ignore Errors (or Alert if you want to see them)

Select any number of variables and it'll create properties and syns for all of them. It'll even create/edit your dalloc method as necessary.

Edit up the results if they are not exactly right (copy vs. retain, etc.)

Handles more things like underbar storage name, behavior, dealloc,…
