+% A category code table enables rapid switching of all category codes in
+% one operation. For \LuaTeX{}, this is possible over the entire Unicode
+% range. For other engines, only the $8$-bit range ($0$-$255$) is covered by
+% such tables.

+% \begin{function}{\cctab_new:N}
+%   \begin{syntax}
+%     \cs{cctab_new:N} \meta{category code table}
+%   \end{syntax}
+%   Creates a new category code table, initially with the codes as

+%   \begin{syntax}
+%     \cs{cctab_const:Nn} \meta{category code table} \Arg{category code set up}
+%   \end{syntax}
+%   Creates a new category code table and applies the
+%   \meta{category code set up} on top of prevailing settings, then saves
+%   as a constant table.
+% \end{function}
+%
+% \begin{function}{\cctab_gset:Nn}
+%   \begin{syntax}
+%     \cs{cctab_gset:Nn} \meta{category code table} \Arg{category code set up}
+%   \end{syntax}
+%   Sets the \meta{category code table} to apply the category codes
+%   which apply when the prevailing régime is modified by the
+%   \meta{category code set up}. Thus within a standard code block
+%   the starting point will be the code applied by \cs{c_code_cctab}.
+%   The assignment of the table is global: the underlying primitive does
+%   not respect grouping.

+%
+% \begin{function}{\cctab_begin:N}
+%   \begin{syntax}
+%     \cs{cctab_begin:N} \meta{category code table}
+%   \end{syntax}
+%   Switches the category codes in force to those stored in the
+%   \meta{category code table}.  The prevailing codes before the
+%   function is called are added to a stack, for use with
+%   \cs{cctab_end:}.

+%   As \LuaTeX{} offers engine support for category code tables, and this is
+%   entirely lacking from the other engines, we need two complementary
+%   approaches here. Rather than intermix them, we split the set up based on
+%   engine. (Some future \XeTeX{} may add support, at which point the
+%   conditional here would be subtly different.)
+%
+%   First, the \LuaTeX{} case.
+%    \begin{macrocode}
+\sys_if_engine_luatex:TF
+  {
+%    \end{macrocode}
+%   Creating a new category code table is done slightly differently
+%   from other registers. Low-numbered tables are more efficiently-stored
+%   than high-numbered ones. There is also a need to have a stack of
+%   flexible tables as well as the set of read-only ones. To satisfy both
+%   of these requirements, odd numbered tables are used for read-only
+%   tables, and even ones for the stack. Here, therefore, the odd numbers
+%   are allocated.
+%    \begin{macrocode}
+    \cs_new_protected:Npn \cctab_new:N #1
+      {
+        \__kernel_chk_if_free_cs:N #1
+%<*initex>
+        \int_gadd:Nn \g_@@_allocate_int { 2 }
+        \int_compare:nNnTF
+          \g_@@_allocate_int < { \c_max_register_int + 1 }
+           {
+             \tex_global:D \tex_chardef:D #1 \g_@@_allocate_int
+             \tex_initcatcodetable:D #1
+           }
+           {
+             \__kernel_msg_fatal:nnx
+               { kernel } { out-of-registers } { cctab }
+           }
+%</initex>
+%<*package>
+        \newcatcodetable #1
+        \tex_initcatcodetable:D #1
+%</package>
+      }
+%    \end{macrocode}
+%   The aim here is to ensure that the saved tables are read-only. This is
+%   done by using a stack of tables which are not read only, and actually
+%   having them as \enquote{in use} copies.
+%    \begin{macrocode}
+    \cs_new_protected:Npn \cctab_begin:N #1
+      {
+        \seq_gpush:Nx \g_@@_stack_seq { \tex_the:D \tex_catcodetable:D }
+        \tex_catcodetable:D #1
+        \int_gadd:Nn \g_@@_stack_int { 2 }
+        \int_compare:nNnT \g_@@_stack_int > \c_max_register_int
+          { \__kernel_msg_fatal:nn { kernel } { cctab-stack-full } }
+        \tex_savecatcodetable:D \g_@@_stack_int
+        \tex_catcodetable:D \g_@@_stack_int
+      }
+    \cs_new_protected:Npn \cctab_end:
+      {
+        \int_gsub:Nn \g_@@_stack_int { 2 }
+        \seq_if_empty:NTF \g_@@_stack_seq
+          { \tl_set:Nn \l_@@_tmp_tl { 0 } }
+          { \seq_gpop:NN \g_@@_stack_seq \l_@@_tmp_tl }
+        \tex_catcodetable:D \l_@@_tmp_tl \scan_stop:
+      }
+%    \end{macrocode}
+%   Category code tables are always global, so only one version is needed.
+%   The set up here is simple, and means that at the point of use there is
+%   no need to worry about escaping category codes.
+%    \begin{macrocode}
+    \cs_new_protected:Npn \cctab_gset:Nn #1#2
+      {
+        \group_begin:
+          #2
+          \tex_savecatcodetable:D #1
+        \group_end:
+      }
+  }
+%    \end{macrocode}
+%   Now the case for other engines. Here, we use an integer array for each
+%   table. The index base is out-by-one, so we have an internal function to
+%   handle that. The rest of the approach here is pretty simple: use a stack
+%   of tables, and save to them at each |begin|. Unlike the \LuaTeX{} case,
+%   we can't accidentally alter a saved table, which makes life a little
+%   easier.
+%    \begin{macrocode}
+  {
+    \cs_new_protected:Npn \@@_gstore:Nnn #1#2#3
+      { \intarray_gset:Nnn #1 { #2 + 1 } {#3} }
+%    \end{macrocode}
+%   Following the \LuaTeX{} pattern, a new table starts with \IniTeX{} codes.
+%    \begin{macrocode}
+    \cs_new_protected:Npn \cctab_new:N #1
+      {
+        \intarray_new:Nn #1 { 256 }
+        \int_step_inline:nn { 256 }
+          { \intarray_gset:Nnn #1 {##1} { 12 } }
+        \@@_gstore:Nnn #1 { 0 } { 9 }
+        \@@_gstore:Nnn #1 { 13 } { 5 }
+        \@@_gstore:Nnn #1 { 32 } { 10 }
+        \@@_gstore:Nnn #1 { 37 } { 14 }
