copied!<p>This is the one I came up with based on one I found a long time ago, rewritten in Python and with the improvements that it can generate multiple properties at once, among other things.</p> <p>It will generate properties for all selected instance variable using (copy) as the attribute. </p> <p>There are still some edge cases with multiple @interfaces or @implementations in a file, as well as some with unusual identifiers or asterisk placement (as in *const), but it should cover most typical coding styles. Feel free to edit/post modifications if you fix any of these cases.</p> <pre><code>#!/usr/bin/python # Takes a header file with one or more instance variables selected # and creates properties and synthesize directives for the selected properties. # Accepts google-style instance variables with a tailing underscore and # creates an appropriately named property without underscore. # Entire Document # Home Directory # Discard Output # Display in Alert import os import re import subprocess # AppleScripts for altering contents of files via Xcode setFileContentsScript = """\ on run argv set fileAlias to POSIX file (item 1 of argv) set newDocText to (item 2 of argv) tell application "Xcode" set doc to open fileAlias set text of doc to newDocText end tell end run \ """ getFileContentsScript = """\ on run argv set fileAlias to POSIX file (item 1 of argv) tell application "Xcode" set doc to open fileAlias set docText to text of doc end tell return docText end run \ """ # Get variables from Xcode headerFileText = """%%%{PBXAllText}%%%""" selectionStartIndex = %%%{PBXSelectionStart}%%% selectionEndIndex = %%%{PBXSelectionEnd}%%% selectedText = headerFileText[selectionStartIndex:selectionEndIndex] headerFilePath = """%%%{PBXFilePath}%%%""" # Look for an implementation file with .m or .mm extension implementationFilePath = headerFilePath[:-1] + "m" if not os.path.exists(implementationFilePath): implementationFilePath += "m" instanceVariablesRegex = re.compile( """^\s*((?:(?:\w+)\s+)*(?:(?:\w+)))""" + # Identifier(s) """([*]?)\\s*""" + # An optional asterisk """(\\w+?)(_?);""", # The variable name re.M) # Now for each instance variable in the selected section properties = "" synthesizes = "" for lineMatch in instanceVariablesRegex.findall(selectedText): types = " ".join(lineMatch[0].split()) # Clean up consequtive whitespace asterisk = lineMatch[1] variableName = lineMatch[2] trailingUnderscore = lineMatch[3] pointerPropertyAttributes = "(copy) " # Attributes if variable is pointer if not asterisk: pointerPropertyAttributes = "" newProperty = "@property %s%s %s%s;\n" % (pointerPropertyAttributes, types, asterisk, variableName) # If there's a trailing underscore, we need to let the synthesize # know which backing variable it's using newSynthesize = "@synthesize %s%s;\n" % (variableName, trailingUnderscore and " = %s_" % variableName) properties += newProperty synthesizes += newSynthesize # Check to make sure at least 1 properties was found to generate if not properties: os.sys.stderr.writelines("No properties found to generate") exit(-1) # We want to insert the new properties either immediately after the last # existing property or at the end of the instance variable section findLastPropertyRegex = re.compile("^@interface.*?{.*?}.*?\\n" + "(?:.*^\\s*@property.*?\\n)?", re.M | re.S) headerInsertIndex = findLastPropertyRegex.search(headerFileText).end() # Add new lines on either side if this is the only property in the file addedNewLine = "\n" if re.search("^\s*@property", headerFileText, re.M): # Not the only property, don't add addedNewLine = "" newHeaderFileText = "%s%s%s%s" % (headerFileText[:headerInsertIndex], addedNewLine, properties, headerFileText[headerInsertIndex:]) subprocess.call(["osascript", "-e", setFileContentsScript, headerFilePath, newHeaderFileText]) if not os.path.exists(implementationFilePath): os.sys.stdout.writelines("No implementation file found") exit(0) implementationFileText = subprocess.Popen( ["osascript", "-e", getFileContentsScript, implementationFilePath], stdout=subprocess.PIPE).communicate()[0] # We want to insert the synthesizes either immediately after the last existing # @synthesize or after the @implementation directive lastSynthesizeRegex = re.compile("^\\s*@implementation.*?\\n" + "(?:.*^\\s*@synthesize.*?\\n)?", re.M | re.S) implementationInsertIndex = \ lastSynthesizeRegex.search(implementationFileText).end() # Add new lines on either side if this is the only synthesize in the file addedNewLine = "\n" if re.search("^\s*@synthesize", implementationFileText, re.M): # Not the only synthesize, don't add addedNewLine = "" newImplementationFileText = "%s%s%s%s" % \ (implementationFileText[:implementationInsertIndex], addedNewLine, synthesizes, implementationFileText[implementationInsertIndex:]) subprocess.call(["osascript", "-e", setFileContentsScript, implementationFilePath, newImplementationFileText]) # Switch Xcode back to header file subprocess.Popen(["osascript", "-e", getFileContentsScript, headerFilePath], stdout=subprocess.PIPE).communicate() </code></pre>
