  These commands print certain parts of the theory and proof context.

  Note that there are some further ones available, such as for the set

  of rules declared for simplifications.

  \begin{description}

  \item \hyperlink{command.print-commands}{\mbox{\isa{\isacommand{print{\isaliteral{5F}{\isacharunderscore}}commands}}}} prints Isabelle's outer theory

  syntax, including keywords and command.

  \item \hyperlink{command.print-theory}{\mbox{\isa{\isacommand{print{\isaliteral{5F}{\isacharunderscore}}theory}}}} prints the main logical content of

  the theory context; the ``\isa{{\isaliteral{22}{\isachardoublequote}}{\isaliteral{21}{\isacharbang}}{\isaliteral{22}{\isachardoublequote}}}'' option indicates extra

  verbosity.

  \item \hyperlink{command.print-methods}{\mbox{\isa{\isacommand{print{\isaliteral{5F}{\isacharunderscore}}methods}}}} prints all proof methods

  available in the current theory context.

  \item \hyperlink{command.print-attributes}{\mbox{\isa{\isacommand{print{\isaliteral{5F}{\isacharunderscore}}attributes}}}} prints all attributes

  available in the current theory context.

  \item \hyperlink{command.print-theorems}{\mbox{\isa{\isacommand{print{\isaliteral{5F}{\isacharunderscore}}theorems}}}} prints theorems resulting from the

  last command; the ``\isa{{\isaliteral{22}{\isachardoublequote}}{\isaliteral{21}{\isacharbang}}{\isaliteral{22}{\isachardoublequote}}}'' option indicates extra verbosity.

  \item \hyperlink{command.find-theorems}{\mbox{\isa{\isacommand{find{\isaliteral{5F}{\isacharunderscore}}theorems}}}}~\isa{criteria} retrieves facts

  from the theory or proof context matching all of given search

  criteria.  The criterion \isa{{\isaliteral{22}{\isachardoublequote}}name{\isaliteral{3A}{\isacharcolon}}\ p{\isaliteral{22}{\isachardoublequote}}} selects all theorems

  whose fully qualified name matches pattern \isa{p}, which may

  contain ``\isa{{\isaliteral{22}{\isachardoublequote}}{\isaliteral{2A}{\isacharasterisk}}{\isaliteral{22}{\isachardoublequote}}}'' wildcards.  The criteria \isa{intro},

  \isa{elim}, and \isa{dest} select theorems that match the

  current goal as introduction, elimination or destruction rules,

  respectively.  The criterion \isa{{\isaliteral{22}{\isachardoublequote}}solves{\isaliteral{22}{\isachardoublequote}}} returns all rules

  that would directly solve the current goal.  The criterion

  \isa{{\isaliteral{22}{\isachardoublequote}}simp{\isaliteral{3A}{\isacharcolon}}\ t{\isaliteral{22}{\isachardoublequote}}} selects all rewrite rules whose left-hand side

  matches the given term.  The criterion term \isa{t} selects all

  theorems that contain the pattern \isa{t} -- as usual, patterns

  may contain occurrences of the dummy ``\isa{{\isaliteral{5F}{\isacharunderscore}}}'', schematic

  variables, and type constraints.

  Criteria can be preceded by ``\isa{{\isaliteral{22}{\isachardoublequote}}{\isaliteral{2D}{\isacharminus}}{\isaliteral{22}{\isachardoublequote}}}'' to select theorems that

  do \emph{not} match. Note that giving the empty list of criteria

  yields \emph{all} currently known facts.  An optional limit for the

  number of printed facts may be given; the default is 40.  By

  default, duplicates are removed from the search result. Use

  \isa{with{\isaliteral{5F}{\isacharunderscore}}dups} to display duplicates.

  \item \hyperlink{command.find-consts}{\mbox{\isa{\isacommand{find{\isaliteral{5F}{\isacharunderscore}}consts}}}}~\isa{criteria} prints all constants

  whose type meets all of the given criteria. The criterion \isa{{\isaliteral{22}{\isachardoublequote}}strict{\isaliteral{3A}{\isacharcolon}}\ ty{\isaliteral{22}{\isachardoublequote}}} is met by any type that matches the type pattern

  \isa{ty}.  Patterns may contain both the dummy type ``\isa{{\isaliteral{5F}{\isacharunderscore}}}''

  and sort constraints. The criterion \isa{ty} is similar, but it

  also matches against subtypes. The criterion \isa{{\isaliteral{22}{\isachardoublequote}}name{\isaliteral{3A}{\isacharcolon}}\ p{\isaliteral{22}{\isachardoublequote}}} and

  the prefix ``\isa{{\isaliteral{22}{\isachardoublequote}}{\isaliteral{2D}{\isacharminus}}{\isaliteral{22}{\isachardoublequote}}}'' function as described for \hyperlink{command.find-theorems}{\mbox{\isa{\isacommand{find{\isaliteral{5F}{\isacharunderscore}}theorems}}}}.

  \item \hyperlink{command.thm-deps}{\mbox{\isa{\isacommand{thm{\isaliteral{5F}{\isacharunderscore}}deps}}}}~\isa{{\isaliteral{22}{\isachardoublequote}}a\isaliteral{5C3C5E7375623E}{}\isactrlsub {\isadigit{1}}\ {\isaliteral{5C3C646F74733E}{\isasymdots}}\ a\isaliteral{5C3C5E7375623E}{}\isactrlsub n{\isaliteral{22}{\isachardoublequote}}}

  visualizes dependencies of facts, using Isabelle's graph browser

  tool (see also \cite{isabelle-sys}).

  \item \hyperlink{command.unused-thms}{\mbox{\isa{\isacommand{unused{\isaliteral{5F}{\isacharunderscore}}thms}}}}~\isa{{\isaliteral{22}{\isachardoublequote}}A\isaliteral{5C3C5E697375623E}{}\isactrlisub {\isadigit{1}}\ {\isaliteral{5C3C646F74733E}{\isasymdots}}\ A\isaliteral{5C3C5E697375623E}{}\isactrlisub m\ {\isaliteral{2D}{\isacharminus}}\ B\isaliteral{5C3C5E697375623E}{}\isactrlisub {\isadigit{1}}\ {\isaliteral{5C3C646F74733E}{\isasymdots}}\ B\isaliteral{5C3C5E697375623E}{}\isactrlisub n{\isaliteral{22}{\isachardoublequote}}}

  displays all unused theorems in theories \isa{{\isaliteral{22}{\isachardoublequote}}B\isaliteral{5C3C5E697375623E}{}\isactrlisub {\isadigit{1}}\ {\isaliteral{5C3C646F74733E}{\isasymdots}}\ B\isaliteral{5C3C5E697375623E}{}\isactrlisub n{\isaliteral{22}{\isachardoublequote}}}

  or their parents, but not in \isa{{\isaliteral{22}{\isachardoublequote}}A\isaliteral{5C3C5E697375623E}{}\isactrlisub {\isadigit{1}}\ {\isaliteral{5C3C646F74733E}{\isasymdots}}\ A\isaliteral{5C3C5E697375623E}{}\isactrlisub m{\isaliteral{22}{\isachardoublequote}}} or their parents.

  If \isa{n} is \isa{{\isadigit{0}}}, the end of the range of theories

  defaults to the current theory. If no range is specified,

  only the unused theorems in the current theory are displayed.

  \item \hyperlink{command.print-facts}{\mbox{\isa{\isacommand{print{\isaliteral{5F}{\isacharunderscore}}facts}}}} prints all local facts of the

  current context, both named and unnamed ones.

  \item \hyperlink{command.print-binds}{\mbox{\isa{\isacommand{print{\isaliteral{5F}{\isacharunderscore}}binds}}}} prints all term abbreviations

  present in the context.

  Isabelle file specification may contain path variables (e.g.\

  \verb|$ISABELLE_HOME|) that are expanded accordingly.  Note

  that \verb|~| abbreviates \verb|$USER_HOME|, and
