NAME
osacompile -- compile AppleScripts and other OSA language scripts SYNOPSIS
osacompile [-l language] [-e command] [-o name] [-d] [-r type:id] [-t type] [-c creator] [-x] [-s] [-u] [-a arch] [file ...] DESCRIPTION
osacompile compiles the given files, or standard input if none are listed, into a single output script. Files may be plain text or other compiled scripts. The options are as follows: -l language Override the language for any plain text files. Normally, plain text files are compiled as AppleScript. -e command Enter one line of a script. Script commands given via -e are prepended to the normal source, if any. Multiple -e options may be given to build up a multi-line script. Because most scripts use characters that are special to many shell programs (e.g., AppleScript uses single and double quote marks, ``('', ``)'', and ``*''), the command will have to be correctly quoted and escaped to get it past the shell intact. -o name Place the output in the file name. If -o is not specified, the resulting script is placed in the file ``a.scpt''. The value of -o partly determines the output file format; see below. -x Save the resulting script as execute-only. The following options are only relevant when creating a new bundled applet or droplet: -s Stay-open applet. -u Use startup screen. -a arch Create the applet or droplet for the specified target architecture arch. The allowable values are ``ppc'', ``i386'', and ``x86_64''. The default is to create a universal binary. The following options control the packaging of the output file. You should only need them for compatibility with classic Mac OS or for cus- tom file formats. -d Place the resulting script in the data fork of the output file. This is the default. -r type:id Place the resulting script in the resource fork of the output file, in the specified resource. -t type Set the output file type to type, where type is a four-character code. If this option is not specified, the creator code will not be set. -c creator Set the output file creator to creator, where creator is a four-character code. If this option is not specified, the creator code will not be set. If no options are specified, osacompile produces a Mac OS X format script file: data fork only, with no type or creator code. If the -o option is specified and the file does not already exist, osacompile uses the filename extension to determine what type of file to create. If the filename ends with ``.app'', it creates a bundled applet or droplet. If the filename ends with ``.scptd'', it creates a bun- dled compiled script. Otherwise, it creates a flat file with the script data placed according to the values of the -d and -r options. EXAMPLES
To produce a script compatible with classic Mac OS: osacompile -r scpt:128 -t osas -c ToyS example.applescript SEE ALSO
