- Answers:
-
- ------------------------------
-
- Subject: 1. How do I set up slrn to read a score file?
-
- In order for slrn to read a score file, it must know the name of the
- score file. This is specified by putting the appropriate line in your
- .slrnrc file. For example, if the name of the score file is `Score' and
- it is located in the News subdirectory, then add the line:
-
- scorefile "News/Score"
-
- to your .slrnrc file.
-
- ------------------------------
-
- Subject: 2. What is the format of an slrn score file?
-
- The format is simple. It consists sections that scores that are to be
- applied to one or more newsgroups. Each section must start with a line
- that contains the name of the newsgroup, enclosed in square brackets,
- for which the scores defined by that section apply.
-
- For example, a line of the form:
-
- [sci.physics.*]
-
- indicates the beginning of a section of scores for the sci.physics
- hierarchy of newsgroups.
-
- Individual scores of a section start with the `Score' keyword. It
- indicates how many points are to be awarded to the article if it passes
- the test defined by the score. For example,
-
- Score: 100
- Subject: neutrino
-
- defines a score of 100 points to an article if the subject contains the
- word `neutrino'.
-
- It is also possible to score an article based on more than one header.
- For example,
-
- Score: 1000
- Subject: path integral
- From: Richard Feynman
-
- gives an article a score of 1000 if the subject is about path integrals
- and the author is ``Richard Feynman''.
-
- A score of -9999 is a special score. If an article scores this value on
- a given test, any other tests for the article will be skipped and the
- article will be killed.
-
- If the first character of a score is `=', the article will given the
- score and the rest of the tests will be skipped. For example,
-
- [sci.physics.*]
-
- Score: =1000
- From: @space.mit.edu
-
- Score: -9999
- Xref: astrology
-
- defines two tests for the sci.physics hierarchy of newsgroups. Since
- the first score starts with the `=' character, any article that whose
- author's email address contains `space.mit.edu' will be given 1000
- points and the rest of the tests will be skipped. The second test
- assigns a score of -9999 to any article cross posted to an astrology
- newsgroup. Since the score defined by this test is -9999, the article
- will be killed. Together these two tests indicate that any article
- cross posted to an astrology newsgroup is killed except if the author is
- from space.mit.edu in which case the article is awarded 1000 points.
-
- The `~' character may used used as a NOT operator. For example, the
- previous score can (almost) be written:
-
- [sci.physics.*]
-
- Score: -9999
- ~From: @space.mit.edu
- Xref: astrology
-
- This simply says to kill any article that was cross posted to an
- astrology group UNLESS the author is from space.mit.edu.
-
- Finally the ``Score'' keyword can be followed by 2 colons to indicate
- that any the score is awarded to the article if any of the tests defined
- by the score are passed. For example,
-
- Score:: 1000
- Subject: neutrino
- Subject: fermion
-
- assigns a score of 1000 to an article if its subject line contains
- either neutrino or photon.
-
- ------------------------------
-
- Subject: 3. How do I assign a score to a specific subject, e.g., ``test'' messages?
-
- Score: -9999
- Subject: test
-
- ------------------------------
-
- Subject: 4. How do I score postings from a specific person?
-
- Score: -9999
- From: name@who\.knows\.where
-
- assigns a score of -9999 to the person name@who.knows.where.
-
- ------------------------------
-
- Subject: 5. How do I score articles from a specific site?
-
- Score: -9999
- From: @who\.knows\.where
-
- will give a score of -9999 to an From line that contains
- `@who.knows.where'.
-
- ------------------------------
-
- Subject: 6. How do I score followups?
-
- Assume a followup either contains a subject starting with `Re:' or has a
- references header. To assign a score of -9999 to such an article use:
-
- Score:: -9999
- Subject: ^Re:
- References: .
-
- Note the use of the double colon following the score keyword. This
- indicates that the score is an OR type expression. This means that the
- above score will pick out articles with EITHER subjects that begin with
- `Re:' OR have a references line.
-
- To score articles with BOTH subjects with `Re:' AND a references headers,
- use the single colon form:
-
- Score: -9999
- Subject: ^Re:
- References: .
-
- Single colon forms are AND expressions.
-
- ------------------------------
-
- Subject: 7. How do I kill cross posts from a specific group?
-
- You have two choices: either use the `Xref' header or the `Newsgroups'
- header. It is best to avoid the `Newsgroups' header if possible, that
- is, try to use the Xref header.
-
- Assume that you want to score any article that was cross-posted to an
- ``astrology'' newsgroup. Then use one of the following forms:
-
- Score: -9999
- Xref: astrology
-
- Score: -9999
- Newsgroups: astrology
-
- Again, try to avoid using the last form if possible.
-
- ------------------------------
-
- Subject: 8. How do I score all cross-posts?
-
- Like the previous answer you have two choices: to use the Xref header
- (preferred) or the Newsgroups header. The first choice uses the fact
- that a cross-posted article will have two colons in the Xref header
- field. So, use a score of the form:
-
- Score: -9999
- Xref: :.*:
-
- If you do not have the option of using the Xref header, use:
-
- Score: -9999
- Newsgroups: ,
-
- ------------------------------
-
- Subject: 9. I know how to kill posts from a specific person. How do I make it so I
- read _only_ the posts from a specific person?
-
- The answer is simple: kill posts by everyone else. Assume that you want
- to only read posts by someone whose from line contains: someone@i.like.
- Then use a score of the form:
-
- Score: -9999
- ~From: someone@i\.like
-
- Note the use of the NOT indicator (~).
-
- Subject: 10. How do I score articles that have no references line but whose
- subject line starts with ``Re:''
-
- Define a score based on the references header and the subject headers,
- e.g.,
-
- Score: -9999
- ~References: .
- Subject: ^Re:
-
- Here the the references line simply says that the article must NOT have a
- references header. The subject header uses a regular expressions that
- says ``Re:'' must occur at the beginning of the subject. This will match
- the strings "Re:", "re:", "rE:", and "RE:". To match only "Re:", use the
- regular expression
-
- Subject: ^\cRe:
-
- Here \c turns on case-sensitivity. To turn it off, use \C.
-
- 11. How do I score subject headers that contain only uppercase characters?
-
- Use something like:
-
- Score: -9999
- ~Subject: \c[a-z]
-
- This will assign a score of -9999 to any article whose subject header
- does NOT contain a lowercase character. To also kill followups to such
- articles use:
-
- Score:: -9999
- ~Subject: \c[a-z]
- ~Subject: ^Re: \c.*[a-z]
-
