Method Detail

gensym

public static java.lang.String gensym(java.lang.String base)

getSystemTempDir

public static java.lang.String getSystemTempDir()

getQnameParent

public static java.lang.String getQnameParent(java.lang.String qname)

Returns the parent qname of qname -- everything up to the last dot (exclusive), or if there are no dots, the empty string.

moduleQname

public static java.lang.String moduleQname(java.lang.String file)

Determines the fully-qualified module name for the specified file. A module's qname is a function of the module's absolute path and the sys path; it does not depend on how the module name may have been specified in import statements. The module qname is the relative path of the module under the load path, with slashes converted to dots.

Parameters:

file - absolute canonical path to a file (__init__.py for dirs)

Returns:

null if file is not somewhere under the load path

arrayToString

public static java.lang.String arrayToString(java.util.Collection<java.lang.String> strings)

arrayToSortedStringSet

public static java.lang.String arrayToSortedStringSet(java.util.Collection<java.lang.String> strings)

moduleNameFor

public static java.lang.String moduleNameFor(java.lang.String path)

Given an absolute path to a file (not a directory), returns the module name for the file. If the file is an __init__.py, returns the last component of the file's parent directory, else returns the filename without path or extension.

joinPath

public static java.io.File joinPath(java.io.File dir,
                                    java.lang.String file)

joinPath

public static java.io.File joinPath(java.lang.String dir,
                                    java.lang.String file)

writeFile

public static void writeFile(java.lang.String path,
                             java.lang.String contents)
                      throws java.lang.Exception

Throws:

java.lang.Exception

readFile

public static java.lang.String readFile(java.lang.String filename)
                                 throws java.lang.Exception

Throws:

java.lang.Exception

readFile

public static java.lang.String readFile(java.io.File path)
                                 throws java.lang.Exception

Throws:

java.lang.Exception

getBytesFromFile

public static byte[] getBytesFromFile(java.io.File file)
                               throws java.io.IOException

Throws:

java.io.IOException

getMD5

public static java.lang.String getMD5(java.io.File path)
                               throws java.lang.Exception

Throws:

java.lang.Exception

getMD5

public static java.lang.String getMD5(byte[] fileContents)
                               throws java.lang.Exception

Throws:

java.lang.Exception

canonicalize

public static java.lang.String canonicalize(java.lang.String path)

Return absolute path for path. Make sure path ends with SEP if it's a directory. Does _not_ resolve symlinks, since the caller may need to play symlink tricks to produce the desired paths for loaded modules.
