ObeyFileCreator

public class BatchFileCreator
extends Object

This tool creates batch file versions of all shell scripts. Shell scripts are turned into batch files as follows:

• file is copied as <script name>.bat with:
  • first letter of script name capitalized
  • script names ending in (j|w|e)ar(s) made to end in (J|W|E)ar(s)
  • scripts names ending in on made to end in On, and those ending in off made to end in Off
  • scripts names beginning with make, docs, shift, push, distribute, release, copy, tar, count or kill have next letter capitalized
  • scripts names beginning with run, monitor, restart, status, heimlich or flush have next letter capitalized
  • scripts names beginning with create, rewrite, unstrip or strip have next letter capitalized
  • scripts names beginning with refresh, update, revert or commit have next letter capitalized
• # comments become rem comments
• @echo off is added
• cp becomes copy
• mv becomes move
• rm becomes del
• commands expressed as paths are reduced to command filename only
• in parameters which are not quoted (this allows URLs and passwords to be treated literally):
  • / becomes \
  • : becomes ;
  • $ becomes %
  • ~/Projects becomes \Projects
• Backticks are executed and their results are statically entered as parameters in the resulting script. This means that if the results change, you will need to recreate the batch file. The backtick commands are not translated in any way, so if they contain OS dependent stuff, then the conversion can only be performed in the source operating system. Backticks which require parameter substuitutions will not work, and will be converted to the string "null"
• Piping is removed, so make sure you don't use pipes for operational code intended for conversion to a batch scripts

This is all pretty simplistic. If your shell scripts are using full pathnames as command paths, or a lot of switches or operational pipes, you will have problems. Also, the above is the complete command set you can use unless there is an equivalent executable in your DOS environment. e.g. You can call java and javac provided you have installed these into your DOS environment.

BatchFileCreator

public BatchFileCreator()

Method Detail

main

public static void main(String[] argv)
                 throws Throwable

Initiates the BatchFileCreator tool.

• The switch "-single" introduces the following parameters as single filenames. If you don't specify a switch, "-single" is assumed.
• The switch "-multi" introduces the following parameters as directory names, which are recursively searched for all ".sh" script files.

Parameters:

argv - arguments are filenames, directory names or switches (one of "-single" or "-multi").

Throws:

IOException - if the input files could not be read or the output files could not be written.

SecurityException - if the configured security policy is too restrictive.

Throwable - if something else goes wrong.

createBatchFile

public static boolean createBatchFile(String toRewrite)
                               throws InterruptedException,
                                      IOException,
                                      SecurityException

Produce a batch file copy of a shell script.

Parameters:

toRewrite - the name of the file to be copied.

Returns:

true if the file was successfully rewritten, false if the file remains unchanged.

Throws:

SecurityException - if the configured security policy is too restrictive.

IOException - if the input files could not be read or the output file could not be written.

InterruptException - another thread interrupted us.

InterruptedException

translateLeaf

protected static String translateLeaf(String leaf)

rewriteAsBatch

public static void rewriteAsBatch(Reader input,
                                  PrintWriter output,
                                  File parentDir)
                           throws InterruptedException,
                                  IOException

Produce a batch file corresponding to a shell script file.

Parameters:

input - the Reader from which the original shell script should be read.

output - the PrintWriter to which the created batch file should be written.

parentDir - the directory containing the input file.

Throws:

IOException - if the input file could not be read or the output file could not be written.

InterruptException - another thread interrupted us.

InterruptedException

getBacktickProcess

                                            File parentDir)
                                     throws IOException
