<title>Defining and Using Filters</title>
|
|
|
|
<para>You may already have read about using filters in the chapter explaining
|
|
the configuration of &knode;; there, we were talking about the built-in
|
|
filters provided by &knode; there. You can configure the built-in
|
|
filters like all the others. The screenshot below shows the dialog box for
|
|
configuring the filters.</para>
|
|
|
|
<tip><para>While filters and scoring are very powerful and have many
|
|
uses, one of the most common requirements is simply to add all posts
|
|
written by someone you don't wish to read to a
|
|
<quote>killfile</quote>. At the <link linkend="killfiles">end of this
|
|
section</link> is a quick guide to using filters and scores to create
|
|
such a killfile.</para></tip>

<para>First we will create a new filter. You may, at some point, want

to find your own articles amongst all the others; or, you may not
|
|
want to see the articles posted by a particular person at all: both cases can
|
|
be solved by a simple filter on the Sender. Here are some

examples:</para>

|

in.</para>
|

|
|
<caution>
|
|
<para>It is generally undesirable to post articles in multiple

newsgroups: please think twice about it; if you are not sure where to

post your article ask in one of the possible groups — somebody will

<title>Redirect Followups</title>
|
|
|
|
<para>The main use of this feature is when a thread has gone
|
|
off topic for the newsgroup in which it is posted; for example, a thread may
|
|
start in a &kde; newsgroup discussing how to redirect a followup in &knode;,
|
|
but may leads to a dicussion about graphical and text based
|
|
newsreaders.</para>
|
|
|
|
<para>Sometimes it happens that usenet users post an article into the
|
|
wrong newsgroup; very often those articles are just ignored. If it
|
|
looks like the author did this unintentionally, you might like to tell
|
|
them politely and make the followup articles go into the right
|
|
group.</para>
|
|
|
|
<para>Another reason for using <guilabel>Followup-To:</guilabel> is a
|
|
when dealing with articles cross-posted across in multiple newsgroups:
|
|
you should take care that the replies are only posted in one single newsgroup.</para>
|
|
|
|
<para>You can activate this by filling the text box
|
|
<guilabel>Followups - To:</guilabel>; here you can enter the suitable

group. If there are multiple newsgroups in the

<guilabel>Groups:</guilabel> field, they are shown in the drop-down

list.</para>

<tip>
|
|
<para>If you enter <userinput>poster</userinput> here, instead of a

newsgroup.</para>
|
|

<para>Canceling an article means deleting it from the

|
|
|
|
<para>Why should you want to cancel an article? Perhaps you

|
flamed somebody in a rage and now you want to get this article out of
|
|
the newsgroup because you regret what you wrote: a personal insult,

read by everybody, doesn't look good, especially when you regret
|
|
it; so, there is only one thing you can do — cancel the article.</para>
|
|
|
|
<para>Select the article you want to cancel and choose
|
|
<guimenuitem>Cancel article</guimenuitem> from its context menu. If
|
|
you are sure it is the right article, confirm &knode;s question with
|
|
<guibutton>Yes</guibutton>. Now you will be asked if you want to send the
|
|
Cancel message now or later; for this example we decide to send it
|
|
<guibutton>Later</guibutton>. You will notice the new message in the
|
|
folder <guilabel>Outbox</guilabel>.</para>
|
|
|
|
<para>Now we want to look at the so-called cancel message. In the
|

subject you will find something like:</para>

<screen>
|
|
<computeroutput>cancel of <n177m8.1m.ln@konqui.org></computeroutput>
|
|
</screen>
|
|
|
|
<para>This strange letters between the brackets are the Message-ID of
|
|
the article you want to cancel. This message tells the newsserver to
|
|
delete your article: if you look at complete header of this message,
|
|
by selecting <menuchoice><guimenu>View</guimenu><guimenuitem>Show all
|
|
headers</guimenuitem></menuchoice>, you will notice a line with the
|
|
name <emphasis>control</emphasis> and the content <emphasis>cancel
|
|
<xxxxx@ddddd.dd></emphasis> — this line tells the server that
|
|
this message is a control message and, in our case, tells the server to
|
|
cancel your article.</para>
|
|
|

<para>You can still delete the control message from the

<guilabel>Outbox</guilabel> should you change your mind.</para>

<para>Keep in mind that articles can only be identified by their
|
|
Message-IDs; you need this Message-ID if you want to cancel an
|
|
article. Normally, your article gets a Message-ID when it arrives at
|
|
the newsserver — that's why you can only cancel an article once
|
|
it has been published. The articles in the
|
|
<guilabel>Sent</guilabel> folder have no Message-ID, so you cannot cancel
|
|
them from there.</para>
|
|
|
|
<para>There is one exception: if you have configured &knode; to
|
|
generate a Message-ID you can cancel you articles in folder
|
|
<guilabel>Sent</guilabel> too.</para>
|
|
|
|
<para>&knode; allows only to cancel your own articles: it refuses to
|
|
cancel articles from other authors.</para>
|
|
</caution>
|
|
|
|
<warning>
|
|
<para>Since the cancel feature is so easily fooled, by newsreaders
|
|
that let you cancel any post, many news servers do not acknowledge
|
|
cancel messages from posters; even if your own <acronym>ISP</acronym>
|
|
accepts the cancel and passes it on, many other servers will ignore it
|
|
<emphasis>and will not pass it on</emphasis>.</para>
|
|
|

<para>You should consider any previously-sent article, canceled or
|
|
not, to be published and publicly available.</para>

<title>Supersede</title>
|
|
|
|
<para>Supersede overwrites your article with a new version. One reason
|
|
for doing this could be:</para>
|
|
|
|
<para>You have written a long article and have already posted it; now, you
|
|
have found an error in this article: you could cancel this article, and post a
|
|
new, corrected, article; or, you can use Supersede.</para>
|
|
|
|
<para>Select the article in the article view. From its context menu
|
|
select <guimenuitem>Supersede article...</guimenuitem>. &knode; will
|
|
ask you if you really want to overwrite this article; if you confirm with
|
|
<guibutton>Yes</guibutton> the Composer appears.</para>
|
|
|
|
<para>In the Composer you can now make the desired corrections and
|
|
changes. You can then publish this article in the same way as you post
|
|
every other article; when the newsserver receives this article it
|
|
reads some special lines in the header which tell the newsserver to
|
|
supersede the older article. Select
|
|
<menuchoice><guimenu>File</guimenu><guimenuitem>Send
|
|
Later</guimenuitem></menuchoice> for now, because we want to look at
|
|
the article's header in the <guilabel>Outbox</guilabel>.</para>
|
|
|
|
<para>Activate <menuchoice><guimenu>View</guimenu><guimenuitem>Show
|
|
all headers</guimenuitem></menuchoice>, because we want to see all the
|
|
headers the newsserver receives. You will notice a line like:</para>
|
|
|
|
<para>Supersedes: <oggcm8.4n5.ln@konqi.org></para>
|
|
|
|
<para>This is the instruction for the newsserver for superseding the
|
|
article with the Message-ID <oggcm8.4n5.ln@konqi.org> with the
|
|
new article.</para>
|
|
|
|
<para>Besides this, Supersede is used for periodical posted articles, ⪚
|
|
an <acronym>FAQ</acronym>. The new article supersedes the old one and
|
|
the newsgroups do not end up with lots of different versions.</para>
|
|
|
|
<caution>
|
|
<para>Again, using this function is only possible if the article
|
|
already has a Message-ID. Normally, articles get their Message-ID from the
|
|
newsserver: this means that you can only supersede articles which have
|
|
already been published.</para>
|
|
|
|
<para>You can configure &knode; to generate this Message-ID, then you can
|
|
supersede your articles in the folder <guilabel>Sent</guilabel>,
|
|
too.</para>
|
|
|
|
<para>&knode; allows you to only supersede your own articles.</para>
|
|
|
|
</caution>
|
|
|
|
<warning>
|
|
<para>As with cancels, supersede messages have been abused in the
|
|
past, with, for example, certain parties sending hundreds or even
|
|
thousands of them to overwrite legitimate posts with random computer
|
|
generated junk; again, as with cancels, many news servers do not
|
|
honor supersede messages, nor do they pass them on.</para>

<para>By scoring a thread, you determine its importance. &knode;
|
|
allows scores between -100000 and 100000. A normal article will get a
|
|
score of 0 if you do not change this; threads with a score below 0
|
|
are less important than average; threads with a score above 0 are more
|
|
important than average.</para>
|
|
|
|
<para>The score is an attribute of the thread and the articles in this
|
|
thread, so you can use the score for filtering and searching
|
|
articles; for example, you can define a filter to show only
|
|
articles with a score > 0, i.e. all articles in which you are
|
|
specifically interested.</para>
|
|
|
|
<para>The function <guilabel>Watch</guilabel> sets the score of
|
|
all article in a thread to 100; this way they get a high score and &knode;
|
|
labels them with a special icon.</para>
|
|
|
|
<para>The function <guilabel>Ignore</guilabel> does the
|
|
opposite: it scores all articles in a thread with -100 so &knode;

does not show these articles anymore.</para>

<para>You can score an article or a thread manually with the right

mouse button or with the <guimenu>Scoring</guimenu> menu — here you can
|
|
score with <guilabel>Watch Thread</guilabel> and <guilabel>Ignore
|
|

|

score the articles with scoring rules automatically; you can configure these

rules at <menuchoice><guimenu>Settings</guimenu><guimenuitem>Configure

<para>The composer consists of 4 areas: on the left side is the list
|
|
of the rules; with the buttons below the list you can add, delete or
|
|
copy an existing rule; below that you have the possibility to limit
|
|
the rules which are shown — you have the choice whether to show all
|
|
rules or only the rules for a specific <glossterm>newsgroup</glossterm>.</para>
|
|
|
|
<para>If you chose a rule-name in the list you the rule will be displayed
|
|
on the right-hand side; now you can edit the rule. At the top you can change
|
|
the name of the rule and set the newsgroups to which this rule applies.
|
|
You can choose one or
|
|
more than one group, note that group names must be separated by a
|
|
semicolon. You can choose from the subscribed groups with
|
|
the drop-down list and the <guibutton>Add group</guibutton> button; or
|
|
you can use regular expressions and wild cards, ⪚ <quote>.*</quote> for all
|
|
groups. The <guilabel>Expire rule automatically</guilabel> option
|
|
makes it possible to delete the rule automatically after the
|
|
configured number of days; this is useful if a specific person
|
|
behaves badly and you do not want to read anything from this person for a
|
|
few days.</para>
|
|
|
|
<para>In the <guilabel>Condition</guilabel> field you enter the
|
|
condition on which this rule is activated. Normally, you can enter only
|
|
one condition, but you can change this by pressing the
|
|
<guibutton>More</guibutton> and <guibutton>Fewer</guibutton> buttons. If you
|
|
have more than one condition, you must tell knode whether all conditions
|
|
need to be fulfilled or only one of them; this can be done by choosing
|
|
<guilabel>Match all conditions</guilabel> or
|
|
<guilabel>Match any condition</guilabel> respectively.
|
|
</para>
|
|
|
|
<para>Each condition consists of 2 drop-down lists and a text
|
|
field. In the first list you chose the part of the message which should
|
|
be used for the condition — this part will be compared with the text
|
|
field; the second drop-down list tells &knode; how it is to be
|
|
compared, for example, whether the chosen header should be identical
|
|
to the text entered in the text field, or if it just needs to match part of it.
|
|
Regular expressions are allowed, too.
|
|
If you check <guilabel>Not</guilabel> then the conditions under which
|
|
the condition is satisfied are reversed, and the condition will be satisfied
|
|
if the opposite of its shown conditions is true.</para>
|
|
|
|
<para>Now, let's have a look at some
|
|
examples.</para>
|
|
|
|
<itemizedlist>
|
|
<listitem>
|
|
<para>Maybe you want to filter away all the postings by Theodor
|
|
Test; to do this choose the
|
|
<guilabel>From</guilabel> header line from the first drop-down
|
|
list, choose <guilabel>is exactly the same as</guilabel> from the second
|
|
drop-down list, and enter his name in the text field.
|
|
But, before doing this you should have a
|
|
look at the <glossterm>header</glossterm> of one of Theodor's
|
|
articles and see what is in the <quote>From</quote> line.</para>
|
|
</listitem>
|
|
<listitem>
|
|
<para>If you do not want to read articles with more than 100 lines, choose
|
|
the header entry <guilabel>Lines</guilabel> from the first drop-down
|
|
list, choose <guilabel>greater than</guilabel> from the second, and enter
|
|
<userinput>100</userinput> in the text field. You probably, then, want to
|
|
score down the message.</para>
|
|
</listitem>
|
|
<listitem>
|
|
<para>Last example: of course, you're very interested in every article
|
|
that refers to &knode;. Choose the header entry
|
|
<guilabel>Subject</guilabel>, then <guilabel>contains substring</guilabel>
|
|
and enter <userinput>knode</userinput> in the text field. But what do
|
|
you do if &knode; is not mentioned in the
|
|
<guilabel>Subject</guilabel>? I suggest using a regular
|
|
expression: change <guilabel>contains substring</guilabel> to
|
|
<guilabel>matches regular expression</guilabel> and type
|
|
<userinput>knode|newsreader|usenet</userinput> into the text
|
|
field to match either knode, newsreader or usenet — the <userinput>|</userinput> symbol
|
|
means OR. Alternatively, you can make 3 conditions — one that matches knode,
|
|
one that matches newsreader and so on — and choose
|
|
<guilabel>Match any condition</guilabel>; but, this needs a lot of
|
|
space and it is not very elegant, is it?</para>
|
|
</listitem>
|
|
|
|
</itemizedlist>
|
|
|
|
<para>Once your condition is ready you should set an action down in the
|
|
<guilabel>Actions</guilabel> section. The most important action is
|
|
<guilabel>adjust score</guilabel>; if this action is chosen you can
|
|
raise or lower the score, by the configured value, for articles to which
|
|
this rule applies. &knode; can also show you a little message when finding
|
|
such an article or colorize the header in the article list; for example, you could make
|
|
interesting articles scraeming pink so you would notice them very
|
|
quickly.</para>
|
|
|
|
<para>When leaving the editor, or when the
|
|
<menuchoice><guimenu>Scoring</guimenu><guimenuitem>Recalculate
|
|
scores</guimenuitem></menuchoice> menu item is chosen, the rules are executed; furthermore,
|
|
the rules are automatically used for new
|
|
<glossterm>articles</glossterm>. Scoring makes the most sense when
|
|
used with filters: by scoring some articles down and filtering them away
|
|
they won't appear in the article list.</para>

reply-to address and signature to use with that group.</para>
|

<para>It is easy to set group identities. First, with the right mouse button,

click on the name of the newsgroup in which to have a different identity in; then,
