gnus: Article Washing
3.18.4 Article Washing
----------------------
We call this “article washing” for a really good reason. Namely, the
‘A’ key was taken, so we had to use the ‘W’ key instead.
“Washing” is defined by us as “changing something from something to
something else”, but normally results in something looking better.
Cleaner, perhaps.
Customizing Articles, if you want to change how Gnus displays
articles by default.
‘C-u g’
This is not really washing, it’s sort of the opposite of washing.
If you type this, you see the article exactly as it exists on disk
or on the server.
‘g’
Force redisplaying of the current article
(‘gnus-summary-show-article’). This is also not really washing.
If you type this, you see the article without any previously
applied interactive Washing functions but with all default
treatments (Customizing Articles).
‘W l’
Remove page breaks from the current article
(‘gnus-summary-stop-page-breaking’). Misc Article, for
page delimiters.
‘W r’
Do a Caesar rotate (rot13) on the article buffer
(‘gnus-summary-caesar-message’). Unreadable articles that tell you
to read them with Caesar rotate or rot13. (Typically offensive
jokes and such.)
It’s commonly called “rot13” because each letter is rotated 13
positions in the alphabet, e.g., ‘B’ (letter #2) -> ‘O’ (letter
#15). It is sometimes referred to as “Caesar rotate” because
Caesar is rumored to have employed this form of, uh, somewhat weak
encryption.
‘W m’
Morse decode the article buffer (‘gnus-summary-morse-message’).
‘W i’
Decode IDNA encoded domain names in the current articles. IDNA
encoded domain names looks like ‘xn--bar’. If a string remain
unencoded after running invoking this, it is likely an invalid IDNA
string (‘xn--bar’ is invalid). You must have GNU Libidn
(<http://www.gnu.org/software/libidn/>) installed for this command
to work.
‘W t’
‘t’
Toggle whether to display all headers in the article buffer
(‘gnus-summary-toggle-header’).
‘W v’
Toggle whether to display all headers in the article buffer
permanently (‘gnus-summary-verbose-headers’).
‘W o’
Treat overstrike (‘gnus-article-treat-overstrike’).
‘W d’
Treat M****s*** sm*rtq**t*s according to
‘gnus-article-dumbquotes-map’ (‘gnus-article-treat-dumbquotes’).
Note that this function guesses whether a character is a sm*rtq**t*
or not, so it should only be used interactively.
Sm*rtq**t*s are M****s***’s unilateral extension to the character
map in an attempt to provide more quoting characters. If you see
something like ‘\222’ or ‘\264’ where you’re expecting some kind of
apostrophe or quotation mark, then try this wash.
‘W U’
Translate many non-ASCII characters into their ASCII equivalents
(‘gnus-article-treat-non-ascii’). This is mostly useful if you’re
on a terminal that has a limited font and doesn’t show accented
characters, “advanced” punctuation, and the like. For instance,
‘»’ is translated into ‘>>’, and so on.
‘W Y f’
Full deuglify of broken Outlook (Express) articles: Treat
dumbquotes, unwrap lines, repair attribution and rearrange
citation. (‘gnus-article-outlook-deuglify-article’).
‘W Y u’
Unwrap lines that appear to be wrapped citation lines. You can
control what lines will be unwrapped by frobbing
‘gnus-outlook-deuglify-unwrap-min’ and
‘gnus-outlook-deuglify-unwrap-max’, indicating the minimum and
maximum length of an unwrapped citation line.
(‘gnus-article-outlook-unwrap-lines’).
‘W Y a’
Repair a broken attribution line.
(‘gnus-article-outlook-repair-attribution’).
‘W Y c’
Repair broken citations by rearranging the text.
(‘gnus-article-outlook-rearrange-citation’).
‘W w’
Do word wrap (‘gnus-article-fill-cited-article’).
You can give the command a numerical prefix to specify the width to
use when filling.
‘W Q’
Fill long lines (‘gnus-article-fill-long-lines’).
‘W C’
Capitalize the first word in each sentence
(‘gnus-article-capitalize-sentences’).
‘W c’
Translate CRLF pairs (i.e., ‘^M’s on the end of the lines) into LF
(this takes care of DOS line endings), and then translate any
remaining CRs into LF (this takes care of Mac line endings)
(‘gnus-article-remove-cr’).
‘W q’
Treat quoted-printable (‘gnus-article-de-quoted-unreadable’).
Quoted-Printable is one common MIME encoding employed when sending
non-ASCII (i.e., 8-bit) articles. It typically makes strings like
‘déjà vu’ look like ‘d=E9j=E0 vu’, which doesn’t look very readable
to me. Note that this is usually done automatically by Gnus if the
message in question has a ‘Content-Transfer-Encoding’ header that
says that this encoding has been done. If a prefix is given, a
charset will be asked for.
‘W 6’
Treat base64 (‘gnus-article-de-base64-unreadable’). Base64 is one
common MIME encoding employed when sending non-ASCII (i.e., 8-bit)
articles. Note that this is usually done automatically by Gnus if
the message in question has a ‘Content-Transfer-Encoding’ header
that says that this encoding has been done. If a prefix is given,
a charset will be asked for.
‘W Z’
Treat HZ or HZP (‘gnus-article-decode-HZ’). HZ (or HZP) is one
common encoding employed when sending Chinese articles. It
typically makes strings look like ‘~{<:Ky2;S{#,NpJ)l6HK!#~}’.
‘W A’
Translate ANSI SGR control sequences into overlays or extents
(‘gnus-article-treat-ansi-sequences’). ANSI sequences are used in
some Chinese hierarchies for highlighting.
‘W u’
Remove newlines from within URLs. Some mailers insert newlines
into outgoing email messages to keep lines short. This
reformatting can split long URLs onto multiple lines. Repair those
URLs by removing the newlines (‘gnus-article-unsplit-urls’).
‘W h’
Treat HTML (‘gnus-article-wash-html’). Note that this is usually
done automatically by Gnus if the message in question has a
‘Content-Type’ header that says that the message is HTML.
If a prefix is given, a charset will be asked for. If it is a
number, the charset defined in
‘gnus-summary-show-article-charset-alist’ (Paging the
Article) will be used.
The default is to use the function specified by
‘mm-text-html-renderer’ (Display Customization
(emacs-mime)Display Customization.) to convert the HTML.
Pre-defined functions you can use include:
‘shr’
Use Gnus simple html renderer.
‘gnus-w3m’
Use Gnus rendered based on w3m.
‘w3m’
Use emacs-w3m (http://emacs-w3m.namazu.org/).
‘w3m-standalone’
Use w3m (http://w3m.sourceforge.net/).
‘links’
Use Links (http://links.sf.net/).
‘lynx’
Use Lynx (http://lynx.isc.org/).
‘html2text’
Use html2text—a simple HTML converter included with Gnus.
‘W b’
Add clickable buttons to the article (‘gnus-article-add-buttons’).
Article Buttons.
‘W B’
Add clickable buttons to the article headers
(‘gnus-article-add-buttons-to-head’).
‘W p’
Verify a signed control message (‘gnus-article-verify-x-pgp-sig’).
Control messages such as ‘newgroup’ and ‘checkgroups’ are usually
signed by the hierarchy maintainer. You need to add the PGP public
key of the maintainer to your keyring to verify the message.(1)
‘W s’
Verify a signed (PGP, PGP/MIME or S/MIME) message
(‘gnus-summary-force-verify-and-decrypt’). Security.
‘W a’
Strip headers like the ‘X-No-Archive’ header from the beginning of
article bodies (‘gnus-article-strip-headers-in-body’).
‘W E l’
Remove all blank lines from the beginning of the article
(‘gnus-article-strip-leading-blank-lines’).
‘W E m’
Replace all blank lines with empty lines and then all multiple
empty lines with a single empty line.
(‘gnus-article-strip-multiple-blank-lines’).
‘W E t’
Remove all blank lines at the end of the article
(‘gnus-article-remove-trailing-blank-lines’).
‘W E a’
Do all the three commands above (‘gnus-article-strip-blank-lines’).
‘W E A’
Remove all blank lines (‘gnus-article-strip-all-blank-lines’).
‘W E s’
Remove all white space from the beginning of all lines of the
article body (‘gnus-article-strip-leading-space’).
‘W E e’
Remove all white space from the end of all lines of the article
body (‘gnus-article-strip-trailing-space’).
