Add file extension and size to sorting capabilities (#1029)
* Add ability to sort by extension and file size. Use the tags [[extension]], [[size]], or [[-size]] in the g:NERDTreeSortOrder list to accomplish this sorting. * Prevent metadata tags being misused in getSortOrderIndex(). * Apply metadata tags only to files. * Update NERDTreeSortOrder in help file. * Update version number in CHANGELOG.

|

This setting is a list of regular expressions which are used to group or sort
|
||||
the nodes under their parent.
|
||||
|
||||
For example, if the setting is: >
|
||||
['\.vim$', '\.c$', '\.h$', '*', 'foobar']
|
||||
<
|
||||
then all .vim files will be placed at the top, followed by all .c files then
|
||||
then all .vim files will be grouped at the top, followed by all .c files then
|
||||
all .h files. All files containing the string 'foobar' will be placed at the
|
||||
end. The star is a special flag: it tells the script that every node that
|
||||
doesn't match any of the other regexps should be placed here.
|
||||
|
||||
If no star is present in NERDTreeSortOrder then one is automatically
|
||||
appended to the array.
|
||||
If no star is present in NERDTreeSortOrder, then one is automatically
|
||||
appended to the end of the list.
|
||||
|
||||
The regex '\/$' should be used to match directory nodes.
|
||||
|
||||
A special flag can be used to sort by the modification timestamps of files and
|
||||
directories. It is either '[[timestamp]]' for ascending, or '[[-timestamp]]'
|
||||
for descending. If placed at the beginning of the list, files and directories
|
||||
are sorted by timestamp, and then by the remaining items in the sort order
|
||||
list. If this flag is in any other position of the list, timestamp sorting is
|
||||
done secondarily. See examples 4, 5, and 6 below.
|
||||
Files can also be sorted by 1) the modification timestamp, 2) the size, or 3)
|
||||
the extension. Directories are always sorted by name. To accomplish this, the
|
||||
following special flags are used:
|
||||
[[timestamp]] [[-timestamp]] [[size]] [[-size]] [[extension]]
|
||||
The hyphen specifies a descending sort; extensions are sorted in ascending
|
||||
order only. If placed at the beginning of the list, files are sorted according
|
||||
to these flags first, and then grouped by the remaining items in the list. If
|
||||
the flags are in any other position of the list, this special sorting is done
|
||||
secondarily. See examples 4, 5, and 6 below.
|
||||
|
||||
After this sorting is done, the files in each group are sorted alphabetically.
