Hey Emacs, this is -*- outline -*- mode
This is the todo list for Wget. I don't have any time-table of when I
plan to implement these features; this is just a list of things I'd
like to see in Wget. I'll work on some of them myself, and I will
accept patches in their direction. The items are not listed in any
particular order. Not all of them are user-visible changes.
* Make `-k' convert <base href=...> too.
* Add option to clobber existing file names (no `.N' suffixes).
* Introduce a concept of "boolean" options. For instance, every
boolean option `--foo' would have a `--no-foo' equivalent for
turning it off. Get rid of `--foo=no' stuff. Short options would
be handled as `-x' vs. `-nx'.
* Implement "thermometer" display (not all that hard; use an
alternative show_progress() if the output goes to a terminal.)
* Add option to only list wildcard matches without doing the download.
* Add case-insensitivity as an option.
* Add option to download all files needed to display a web page
(images, etc.)
* Handle MIME types correctly. There should be an option to (not)
retrieve files based on MIME types, e.g. `--accept-types=image/*'.
* Implement "persistent" retrieving. In "persistent" mode Wget should
treat most of the errors as transient.
* Allow time-stamping by arbitrary date.
* Fix Unix directory parser to allow for spaces in file names.
* Allow size limit to files.
* -k should convert convert relative references to absolute if not
downloaded.
* Recognize HTML comments correctly. Add more options for handling
bogus HTML found all over the 'net.
* Implement breadth-first retrieval.
* Download to .in* when mirroring.
* Add an option to delete or move no-longer-existent files when
mirroring.
* Implement a switch to avoid downloading multiple files (e.g. x and
x.gz).
* Implement uploading (--upload URL?) in FTP and HTTP.
* Rewrite FTP code to allow for easy addition of new commands. It
should probably be coded as a simple DFA engine.
* Recognize more FTP servers (VMS).
* Make HTTP timestamping use If-Modified-Since facility.
* Implement better spider options.
* Add more protocols (e.g. gopher and news), implementing them in a
modular fashion.
* Implement a concept of "packages" a la mirror.
* Implement correct RFC1808 URL parsing.
* Implement HTTP cookies.
* Implement more HTTP/1.1 bells and whistles (ETag, Content-MD5 etc.)
* Support SSL encryption through SSLeay.
