FTP Directory Listing Parsers
Extension point that allows providing extra parsers for the FTP LIST command output.
Apache commons net provides some APIs and factories to costumize the parser and this extension
provides an easy way to setup a custom parser and integrate it into RSE.
The provided extension points will be available as a list in the property "FTP Settings",
allowing the user to select them overriding the default parser.
The string attributes
follow the format described by
Each parser can also specify one or more FTP commands to be sent after establishing the connection in the

label - Name that will be displayed in the FTP Settings dialog
class - Extension of
org.apache.commons.net.ftp.Configurable,org.apache.commons.net.ftp.FTPFileEntryParser implementing the parser for the specific server
defaultDateFormatStr - This property specifies the main date format that will be used by a parser configured by this configuration to parse file timestamps. If this is not specified, such a parser will use as a default value, the most commonly used format which will be in as used in
en_US locales. This should be in the format described for
recentDateFormatStr - This property specifies a secondary date format that will be used by a parser configured by this configuration to parse file timestamps, typically those less than a year old. If this is not specified, such a parser will not attempt to parse using an alternate format.
This is used primarily in unix-based systems.
This should be in the format described for
serverLanguageCode - This property allows user to specify a
two-letter ISO-639 language code that will be used to configure the set of month names used by the file timestamp parser.
If neither this nor the shortMonthNames is specified, parsing will assume English month names, which may or may not be significant, depending on whether the date format(s) specified via defaultDateFormatStr and/or recentDateFormatStr are using
numeric or alphabetic month names.
If the code supplied is not supported here,
month names will be used. We are supporting here those language
codes which, when a
java.util.Locale is constucted
using it, and a
constructed using that Locale, the array returned by the
getShortMonths() method consists solely of three 8-bit ASCII character strings. Additionally,
languages which do not meet this requirement are included if a
common alternative set of short month names is known to be used.
This means that users who can tell us of additional such encodings
may get them added to the list of supported languages by contacting
the Apache Commons Net team.
Please note that this attribute will NOT be used to determine a locale-based date format for the language.
Experience has shown that many if not most FTP servers outside the
United States employ the standard
en_US date format
MMM d yyyy and
MMM d HH:mm
and attempting to deduce this automatically here would cause more
problems than it would solve. The date format must be changed
via the defaultDateFormatStr and/or recentDateFormatStr parameters.
shortMonthNames - This property allows the user to specify a set of month names used by the server that is different from those that may be specified using the setServerLanguageCode property.
This should be a string containing twelve strings each composed of
three characters, delimited by pipe (|) characters. Currently,
only 8-bit ASCII characters are known to be supported. For example, a set of month names used by a hypothetical Icelandic FTP server might conceivably be specified as
serverTimeZoneId - This property allows a time zone to be specified corresponding to that known to be used by an FTP server in file listings. This might be particularly useful to clients such as Ant that try to use these timestamps for dependency checking. This should be one of the identifiers used by
java.util.TimeZone to refer to time zones, for example,
systemTypeRegex - Regular expression used to match with the string returned by the FTP SYST command to autodetect the parser if not specified by the user
priority - Priority used if more than one extension matches the regular expression given by the
ftpSystemTypes attribute. Integer values are allowed.
In case of more than one parser with a matching regular expression, the parser with lower priority number will be used.
If no priority is specified, the default value will be
listCommandModifiers - Modifiers of the FTP "LIST" command. As an example if the LIST command has to be "LIST -l", the contents of this optional field has to be "-l"
<!ELEMENT initCommand EMPTY>
cmd CDATA #REQUIRED
FTP initialization command to perform after connecting to the remote server, when the server's system type is detected to match the current listing parser.
cmd - Command string to execute
