User Level Required: interpreter
Command Syntax:
- )what categories pattern1 [pattern2 ...]
- )what commands pattern1 [pattern2 ...]
- )what domains pattern1 [pattern2 ...]
- )what operations pattern1 [pattern2 ...]
- )what packages pattern1 [pattern2 ...]
- )what synonym pattern1 [pattern2 ...]
- )what things pattern1 [pattern2 ...]
- )apropos pattern1 [pattern2 ...]
Command Description:
This command is used to display lists of things in the system. The patterns
are all strings and, if present, restrict the contents of the lists. Only
those items that contain one or more of the strings as substrings are
displayed. For example,
)what synonym
displays all command synonyms,
)what synonym ver
displays all command synonyms containing the substring ``ver'',
)what synonym ver pr
displays all command synonyms containing the substring ``ver'' or the
substring ``pr''. Output similar to the following will be displayed
---------------- System Command Synonyms -----------------
user-defined synonyms satisfying patterns:
ver pr
)apr ........................... )what things
)apropos ....................... )what things
)prompt ........................ )set message prompt
)version ....................... )lisp *yearweek*
Several other things can be listed with the )what command:
categories displays a list of category constructors.
commands displays a list of system commands available at your
user-level. Your user-level is set via the )set userlevel command. To get
a description of a particular command, such as ``)what'', issue )help
what.
domains displays a list of domain constructors.
operations displays a list of operations in the system library.
It is recommended that you qualify this command with one or more
patterns, as there are thousands of operations available. For example,
say you are looking for functions that involve computation of
eigenvalues. To find their names, try )what operations eig. A rather
large list of operations is loaded into the workspace when this command
is first issued. This list will be deleted when you clear the workspace
via )clear all or )clear completely. It will be re-created if it is
needed again.
packages displays a list of package constructors.
synonym lists system command synonyms.
things displays all of the above types for items containing
the pattern strings as substrings. The command synonym )apropos is
equivalent to )what things.
