2000-10-13 John Wiegley <johnw@gnu.org>
|
||||
|
||||
* eshell/esh-util.el: Added a global form which declares an
|
||||
autoload for `parse-time-string', if that function is not already
|
||||
defined, and if parse-time.el is available on the user's system.
|
||||
|
||||
* eshell/em-ls.el (eshell-ls-applicable): Extended this function
|
||||
to be aware of ange-ftp user info.
|
||||
(eshell-do-ls): Bind `ange-cache'. Also, use
|
||||
`eshell-file-attributes'.
|
||||
(eshell-ls-annotate): Use `eshell-file-attributes'.
|
||||
(eshell-ls-file): Made the user-id printing code a bit smarter.
|
||||
|
||||
* eshell/esh-util.el (eshell-ange-ls-uids): Added variable, to
|
||||
allow identification of alias user ids in remote directories.
|
||||
It's manual, but there's no other way to know when the current
|
||||
user on the local machine, is also the owning user on the remote
|
||||
machine.
|
||||
(fboundp): Bind `ange-cache'.
|
||||
(eshell-directory-files-and-attributes): Re-organized the logic a
|
||||
bit to use `eshell-file-attributes' instead of `file-attributes'.
|
||||
The former is more sensitive to directories that are read via FTP,
|
||||
and knows how to use ange-ftp to determine full attribute
|
||||
information, instead of just the name and last modtime.
|
||||
(eshell-current-ange-uids): Return the current user id when in a
|
||||
remote directory.
|
||||
(eshell-parse-ange-ls): Parse a full directory listing that has
|
||||
been returned by ange-ftp.
|
||||
(eshell-file-attributes): This beefed up version of
|
||||
`file-attributes' is only special if the user is currently in a
|
||||
remote directory, in which case it does a lot of work to find out
|
||||
what the real attributes of a file are, as they appear on the
|
||||
remote machine. This makes usage of remote directories (i.e.,
|
||||
ange-ftp pathnames) much more useful. You can now use Eshell as a
|
||||
full-fledged FTP client, with much more manipulation ability than
|
||||
most other clients.
|
||||
|
||||
* eshell/em-unix.el (eshell-du-prefer-over-ange): Added a new
|
||||
variable, which means that Eshell's du should always be preferred
|
||||
in remote directories.
|
||||
(eshell-shuffle-files): Use `eshell-file-attributes', rather than
|
||||
just `file-attributes'.
|
||||
(eshell-mvcp-template): Bind `ange-cache', to improve performance
|
||||
when reading remote directories. This is an Eshell-specific
|
||||
variable (not part of ange-ftp).
|
||||
(eshell/ln): Bind `ange-cache'.
|
||||
(eshell/du): Added some extra logic for determining when to use
|
||||
Eshell's du (which is slow), and when to use the external version
|
||||
(which may or may not exist).
|
||||
|
||||
* eshell/em-rebind.el (eshell-delchar-or-maybe-eof): Call
|
||||
`eshell-interactive-process', rather than using
|
||||
`get-buffer-process', since backgrounded processes don't count in
|
||||
the context of this function's logic.
|
||||
|
||||
* eshell/esh-arg.el (eshell-parse-double-quote): Moved a call to
|
||||
`forward-char', so that null strings are parsed correctly.
|
||||
|
||||
2000-09-10 John Wiegley <johnw@gnu.org>
|
||||
|
||||
* eshell/em-pred.el (eshell-pred-file-type,
|
||||
eshell-pred-file-links, eshell-pred-file-size): Use
|
||||
`eshell-file-attributes'. This is more correct over ange-ftp.
|
||||
|
||||
* eshell/em-glob.el (eshell-extended-glob): Bind `ange-cache', so
|
||||
that remote file globbing is more efficient.
|
||||
|
||||
* eshell/em-ls.el (eshell-ls-dir): Use `expand-file-name' when
|
||||
gathering the files and attributes within a directory.
|
||||
|
||||
* eshell/em-unix.el (eshell/cat): If any of the files passed on
|
||||
the command line is a special file (not a regular file, directory
|
||||
or symlink), always attempt to call the external version of cat.
|
||||
|
||||
2000-09-06 John Wiegley <johnw@gnu.org>
|

* eshell/esh-mode.el (eshell-find-tag): Corrections to the
|
||||
Eshell-friendly version of find-tag.
