OpenBSD Mailing List Server
Substitution variables and file templates When Majordomo sends a reply message in response to a request, the document that it sends is usually a template. The template may have one or more keyword variables, for which Majordomo automatically substitutes the appropriate value. Substitution variables are composed of a leading dollar sign, followed by capital letters and underscores. For example, when you use the command help overview Near the end of the document, it says Majordomo 2, version $VERSION However, what you see on your screen is Majordomo 2, version 0.1201103110 Majordomo automatically substitutes the version number for the VERSION keyword variable. The most important use of variable substitutions is in the faq, info, and intro files that are available through the commands with the same names. Substitution variables are also used by some configuration settings and by the announce and help commands. Substitution variables are not the same as access rule variables. See "help access_variables" for more information about access variables. As an example of a variable, using this string in a file $MJ will cause the the address of the majordomo email interface to be inserted before the user sees the file contents. When you edit a document that contains substitution variables, be certain to leave enough space for the text that will replace each variable. Otherwise, some lines in the document may be longer than you expected. Variables that are not supported by a particular document or configuration setting will remain unaltered. See "help error_files", "help format_files" and "help reply_files" for a list of documents and the substitutions that they support. The $INCLUDE variable can be used to incorporate a separate document into the current document. This variable must be followed by a dash and the location of a file within the file space of your mailing list. For example, the following substitution: $INCLUDE-help/topics will include the contents of the "help topics" document into the current file. The line that contains the substitution must end immediately after the file location. Included files can also use the $INCLUDE substitution, but more than 3 levels of nesting is taken to be an infinite loop, which will cause an error message to be displayed. The $INCLUDE substitution is supported by reply files, but not by error files or format files. If you misspell a variable, or use one that is not defined, it will appear exactly as you typed it, including the dollar sign. You can keep variable evaluation from happening by preceding the dollar sign with a backslash, as in \$MAJORDOMO which will appear as simply "$MAJORDOMO" after the substitutions are finished. In addition, the text can be padded and justified, as illustrated in this example: $LIST:-18 X $COMMAND:11 The name of the mailing list is padded with spaces to at least 18 characters and left-justified. The command is padded to at least 11 characters and right-justified. If the mailing list name is "aardvark" and the command is "subscribe" then this line would be displayed as aardvark X subscribe Padding in this manner is very useful for commands, such as who-enhanced, that display a table of data with each column aligned properly. See "help get" and "help put" for information on how to see, change, or create the error, format, and reply files that use these substitutions. Standard substitution variables ------------------------------- There is a set of standard substitutions, that apply to most of the Majordomo error, format, and reply files. Their names and values (in the context of the GLOBAL list) are shown in the following list. Naturally, some of the variables (LIST, OWNER, PLIST, REQUEST, SUBLIST, and WHOAMI) will vary depending upon the mailing list. $ARCURL (The URL that allows access to an external archive. This value is determined by the archive_url configuration setting; see "help configset_archive_url" for more information.) $CONFIRM_URL https://lists.openbsd.org/cgi-bin/mj_confirm/domain=openbsd.org?t= (The location of the WWW interface to confirm a subscription, posted message, or other Majordomo command.) $DATE The date at which a request was originally issued; in some cases this may be the Date header from a posted message. $DOMAIN openbsd.org (The name of the current domain, as determined at installation time) $LIST GLOBAL (The name of the current mailing list, or GLOBAL.

Extensions for error and format files ------------------------------------- Beyond the standard reply files, Majordomo comes with error and format files that determine the output of the individual Majordomo commands. Error files are used to display explanations when a command is incorrect, not permitted, or otherwise unavailable. Format files display the output of the individual commands, and vary depending upon the interface. Currently, the e-mail and mj_shell interfaces use the "text" format files, whereas the web interfaces use the "wwwadm" and "wwwusr" format files. There are three extensions to the substitutions which are used by the error and format files. 1. A keyword variable prefixed with a question mark instead of a dollar sign will cause the whole line to be omitted from the output if the value is not set. Example: The archive is available on the web at ?ARCURL 2. A substitution value that is actually an array of values will cause the same line to be displayed multiple times, once for each value in the array. Other substitutions on the same line, which only have one value, will be displayed only on the first line. Example: $LIST:-23 $DESCRIPTION (This example is used by the lists command to display a list name and a multiple-line description of the mailing list. Although the list name only appears on the first line, a 23 space indentation appears on each succeeding line, which keeps the lines of the description aligned with one another.) 3. The special $HELP substitution, following by a colon and the name of a help page (in upper-case letters), will cause a hypertext link to that page to appear in the output of the WWW interfaces. In the text formatting files, the variable is simply replaced by the name of the page, in lower-case letters. Example: You may change your delivery class using the $HELP:SET command. See Also: help access_variables help admin_documents help announce help configset_access_rules (for mailfile and deny usage) help configset_site_name help configset_welcome_files (for additional files that can be sent) help digest (for additional file names and usage) help error_files help format_files help get (obtain existing files) help help help here_document help put (create or update files by email) help reply_files This is the "variables" help document for Majordomo 2, version 0.1201103110. For a list of all help documents, send the following command: help topics in the body of a message to firstname.lastname@example.org.
