F. Invoking the LinkController Programs

Because they use the Perl Getopt::Mixed module, all of the LinkController command line programs respond to the standard POSIX style command line options. At least the following two options will be implemented.

`--help'
This option will give a list of all of the options understood by the program along with brief explanations of what they do. At present it may lie a little, but that is being corrected.
`--version'
This option will give some version information for the program.

You can use the `--help' option to get help on each program, for example:

 
extract-links --help

will give something like

 
extract-links [arguments] [url-base [file-base]]

 -V --version            Give version information for this program
 -h --help --usage       Describe usage of this program.
    --help-opt=OPTION    Give help information for a given option
 -v --verbose[=VERBOSITY] Give information about what the program is doing.  Set
                         value to control what information is given.

 -e --exclude-regex=REGEX Exclude expression for excluding files.
 -p --prune-regex=REGEX  Regular expression for excluding entire directories.
 -d --default-infostrucs handle all default infostrucs (as well as ones listed
                         on command line)

 -l --link-database=FILENAME Database to create link records into.
 -c --config-file=FILENAME Load in an additional configuration file

 -o --out-url-list=FILENAME File to output the url of each link found to
 -i --in-url-list=FILENAME File to input urls from to create links

Extract the link and index information from a directory containing
HTML files or from a set of WWW pages with URLs which begin with the
given URL and which can be found by starting from that URL and
searching other such pages.

You can then use that information to get the program to do what you want.

F.1 Invoking link-report

The `link-report' program prints out status information about links allowing the user to see what needs to be fixed. The default is to print out all of the broken and redirected links that currently occur on the users web pages and which are either redirected or broken.

Before running `link-report' you should probably use `test-link' (see section F.2 Invoking extract-links)to check which links are broken. That may not be needed if your system administrator does it for you. After you have identified broken links you may want to use `fix-link' (see section F.4 Invoking fix-link) to repair the broken links.

FIXME this section should give a better description of each option.

 
link-report [options]

 -V --version            Give version information for this program
 -h --help --usage       Describe usage of this program.
    --help-opt=OPTION    Give help information for a given option
 -v --verbose[=VERBOSITY] Give information about what the program is doing.  Set
                         value to control what information is given.

 -U --uri=URIs           Give URIs which are to be reported on.
 -f --uri-file=FILENAME  Read all URIs in a file (one URI per line).
 -E --uri-exclude=EXCLUDE RE Add a regular expressions for URIs to ignore.
 -I --uri-include=INCLUDE RE Give regular expression for URIs to check (if this
                         option is given others aren't checked).
 -e --page-exclude=EXCLUDE RE Add a regular expressions for pages to ignore.
 -i --page-include=INCLUDE RE Give regular expression for URIs to check (if this
                         option is given others aren't checked).

 -a --all-links          Report information about every URI.
 -b --broken             Report links which are considered broken.

 -m --ignore-missing     Don't complain about links which aren't in the
                         database.
 -g --good               Report links which are probably worth listing.

 -N --no-pages           Report without page list.
    --config-file=FILENAME Load in an additional configuration file
    --link-index=FILENAME Use the given file as the index of which file has what
                         link.
    --link-database=FILENAME Use the given file as the dbm containing links.

 -l --long-list          Where possible, identify the file and long list it
                         (implies infostructure).  This is used for emacs
                         check-all-dired.
 -R --uri-report         Print URIs on separate lines for each link.
 -H --html               Report status of links in html format.

Report on the status of links, getting the links either from the
database, from the index file or from the command line.

F.2 Invoking extract-links

The `test-link' program tests all of the links in the LinkController database storing information about any problems found. It works as a robot contacting the servers where the target of each link is stored and verifying that the resource the link points to is really there.

Before running `test-link' you should probably use `extract-links' (see section F.3 Invoking extract-links) to collect all of the links you want to test and then `build-schedule' (see section F.5 Invoking build-schedule).

FIXME this section should give a better description of each option.

 
test-link [arguments]

 -V --version            Give version information for this program
 -h --help --usage       Describe usage of this program.
    --help-opt=OPTION    Give help information for a given option
 -v --verbose[=VERBOSITY] Give information about what the program is doing.  Set
                         value to control what information is given.
 --quite -q --silent     Program should generate no output except in case of
                         error.
    --no-warn            Avoid issuing warnings about non-fatal problems.

 -c --config-file=FILENAME Load in an additional configuration file
 -u --user-address=STRING Email address for user running link testing.
 -H --halt-time=MINUTES  stop after given number of minutes

    --never-stop         keep running without stopping
    --no-robot           Don't follow robot rules.  Dangerous!!!
 -w --no-waitre=NETLOC-REGEX Home HOST regex: no robot rules.. (danger?)!!!
    --test-now           Test links now not when scheduled (testing only)
    --untested           Test all links which have not been tested.
    --sequential         Put links into schedule in order tested (for testing)
 -H --halt-time=MINUTES  stop after given number of minutes
 -m --max-links=INTEGER  Maximum number of links to test (-1=no limit)

Read the link database and test those links which are due to have been
tested, exiting when the next link to be tested is due after the program
start time.

Don't use --no-robot, except for when you are doing local
testing (that is, you aren't connected to the internet proper).

Don't use --never-stop or --test-now except when you are watching what
is happening.

F.3 Invoking extract-links

The `extract-links' program walks through the users web pages collecting all of the links from those pages and storing them into a database for later checking by the `test-link' program (see section F.2 Invoking extract-links). It can also list the links found into a given file.

After running `extract-links' you should use `build-schedule' (see section F.5 Invoking build-schedule) which will make sure that any new links discovered are scheduled for checking..

FIXME this section should give a better description of each option.

 
extract-links [arguments] [url-base [file-base]]

 -V --version            Give version information for this program
 -h --help --usage       Describe usage of this program.
    --help-opt=OPTION    Give help information for a given option
 -v --verbose[=VERBOSITY] Give information about what the program is doing.  Set                         value to control what information is given.
 --quiet -q --silent     Program should generate no output except in case of
                         error.

 -e --exclude-regex=REGEX Exclude expression for excluding files.
 -p --prune-regex=REGEX  Regular expression for excluding entire directories.
 -d --default-infostrucs handle all default infostrucs (as well as ones listed
                         on command line)

 -l --link-database=FILENAME Database to create link records into.
 -c --config-file=FILENAME Load in an additional configuration file

 -o --out-url-list=FILENAME File to output the URL of each link found to
 -i --in-url-list=FILENAME File to input URLs from to create links

Extract the link and index information from a directory containing
HTML files or from a set of WWW pages with URLs which begin with the
given URL and which can be found by starting from that URL and
searching other such pages.

F.4 Invoking fix-link

The `fix-link' program is designed to repair a broken links across all of the files which LinkController is managing. It does this by looking up index files and seeing files contain the broken link then doing a textual substitution in each of these files. This makes it much faster than searching through all of the files in a set of web pages to see which pages have the broken link.

In order to work properly, `extract-links' (see section F.3 Invoking extract-links) must have been run first to build up the index databases used by `fix-link'.

 
fix-link [options] old-link new-link

 -V --version            Give version information for this program
 -h --help --usage       Describe usage of this program.
    --help-opt=OPTION    Give help information for a given option
 -v --verbose[=VERBOSITY] Give information about what the program is doing.  Set
                         value to control what information is given.
 -q --quiet --silent     Program should generate no output except in case of
                         error.
    --no-warn            Avoid issuing warnings about non-fatal problems.

    --directory=DIRNAME  correct all files in the given directorywhat link.

 -r --relative           Fix relative links (expensive??).
 -t --tree               Fix the link and any others based on it.
 -b --base=FILENAME      Base URI of the document or directory to be fixed.

    --config-file=FILENAME Load in an additional configuration file

Replace any occurences of OLD-LINK with NEW-LINK using link index file
to locate which files OLD-LINK occurs in.

F.5 Invoking build-schedule

The `build-schedule' program makes a schedule for testing links. If run with no options it will make sure that all the links in the LinkController database will be checked at some point in the future.

Before running `build-schedule' you should probably use `extract-links' (see section F.3 Invoking extract-links) to collect all of the links you want to test. Afterwards you should use `test-link' to check which ones are broken (see section F.2 Invoking extract-links).

 
build-schedule [options]

 -V --version            Give version information for this program
 -h --help --usage       Describe usage of this program.
    --help-opt=OPTION    Give help information for a given option
 -v --verbose[=VERBOSITY] Give information about what the program is doing.  Set                         value to control what information is given.
 --quite -q --silent     Program should generate no output except in case of
                         error.
    --no-warn            Avoid issuing warnings about non-fatal problems.

 -l --url-list=FILENAME  File with complete list of URLs to schedule
 -s --schedule=FILENAME  Override location of the schedule
 -t --spread-time=SECONDS Time over which to spread checking; default 10 days
 -S --start-offset=SECONDS Time offset from now for starting work (can be
                         negative)
 -d --ignore-db          Set the time with no regard to curent setting
 -i --ignore-link        Set the time with no regard to link status
    --no-warn            Avoid issuing warnings about non-fatal problems.
    --config-file=FILENAME Load in an additional configuration file

Examine a database of link objects and build a schedule to check those links
which can be used by test-link.
