+.sp
+renderline is the core engine for overtype string processing (frames & textblocks), and the raw mode commandline repl for the Tcl Punk Shell
+.sp
+It is also a central part of an ansi (micro) virtual terminal-emulator of sorts
+.sp
+This system does a half decent job at rendering 90's ANSI art to manipulable colour text blocks that can be joined & framed for layout display within a unix or windows terminal
+.sp
+Renderline helps maintain ANSI text styling reset/replay codes so that the styling of one block doesn't affect another\&.
+.sp
+Calling on the punk::ansi library - it can coalesce codes to keep the size down\&.
+.sp
+It is a giant mess of doing exactly what common wisdom says not to do\&.\&.\&. lots at once\&.
+.sp
+renderline is part of the Unicode and ANSI aware Overtype system which 'renders' a block of text onto a static underlay
+.sp
+The underlay is generally expected to be an ordered set of lines or a rectangular text block analogous to a terminal screen - but it can also be ragged in line length, or just blank\&.
+.sp
+The overlay couuld be similar - in which case it may often be used to overwrite a column or section of the underlay\&.
+.sp
+The overlay could however be a sequence of ANSI-laden text that jumps all over the place\&.
+.sp
+renderline itself only deals with a single line - or sometimes a single character\&.  It is generally called from a loop that does further terminal-like or textblock processing\&.
+.sp
+By suppyling the -info 1 option - it can return various fields indicating the state of the render\&.
+.sp
+The main 3 are the result, overflow_right, and unapplied\&.
+.sp
+Renderline handles cursor movements from either keystrokes or ANSI sequences but for a full system the aforementioned loop will need to be in place to manage the set of lines under manipulation\&.

 .SS NOTES
 .PP
-There are alternative args parsing packages such as:
+For internal functions not requiring features such as solo flags, prefix matching, type checking etc - a well crafted switch statement will be the fastest pure-tcl solution\&.
+.PP
+When functions are called often and/or in inner loops, a switch based solution generally makes the most sense\&.
+For functions that are part of an API a package may be more suitable\&.
+.PP
+The following example shows a switch-based solution that is highly performant (sub microsecond for the no-args case)
+.CS
+
+
+    proc test1_switch {args} {
+        set opts [dict create\\
+            -return "object"\\
+            -frametype "heavy"\\
+            -show_edge  1\\
+            -show_seps  0\\
+            -x a\\
+            -y b\\
+            -z c\\
+            -1 1\\
+            -2 2\\
+            -3 3\\
+        ]
+        foreach {k v} $args {
+            switch -- $k {
+                -return - -show_edge - -show_seps - -frametype - -x - -y - -z - -1 - -2 - -3 {
+                    dict set opts $k $v
+                }
+                default {
+                    error "unrecognised option '$k'\&. Known options [dict keys $opts]"
+                }
+            }
+        }
+        return $opts
+    }
+
+.CE
+.PP
+Note that the switch statement uses literals so that the compiler produces a jump-table for best performance\&.
+.PP
+Attempting to build the switch branch using the values from dict keys $opts will stop the jump table being built\&.
+To create the faster switch statement without repeating the key names, the proc body would need to be built using string map\&.

+use punk::lib::show_jump_tables <procname> to verify that a jump table exists\&.

+.PP
+Package to a allow a safe interpreter to access islands of the
+.PP
+filesystem only, i\&.e\&. restricted directory trees within the
+.PP
+filesystem\&. The package brings back file, open and glob to the child interp
+.PP
+interpreter, though in a restricted manner\&.
+.PP
+JN Warning:
+.PP
+This mechanism can have interactions with package loading from auto_path - needs review\&.

+
+  - <a name='2'></a>__overtype::renderline__ *args*
+
+    renderline is the core engine for overtype string processing \(frames &
+    textblocks\), and the raw mode commandline repl for the Tcl Punk Shell
+
+    It is also a central part of an ansi \(micro\) virtual terminal\-emulator of
+    sorts
+
+    This system does a half decent job at rendering 90's ANSI art to manipulable
+    colour text blocks that can be joined & framed for layout display within a
+    unix or windows terminal
+
+    Renderline helps maintain ANSI text styling reset/replay codes so that the
+    styling of one block doesn't affect another\.
+
+    Calling on the punk::ansi library \- it can coalesce codes to keep the size
+    down\.
+
+    It is a giant mess of doing exactly what common wisdom says not to do\.\.\.
+    lots at once\.
+
+    renderline is part of the Unicode and ANSI aware Overtype system which
+    'renders' a block of text onto a static underlay
+
+    The underlay is generally expected to be an ordered set of lines or a
+    rectangular text block analogous to a terminal screen \- but it can also be
+    ragged in line length, or just blank\.
+
+    The overlay couuld be similar \- in which case it may often be used to
+    overwrite a column or section of the underlay\.
+
+    The overlay could however be a sequence of ANSI\-laden text that jumps all
+    over the place\.
+
+    renderline itself only deals with a single line \- or sometimes a single
+    character\. It is generally called from a loop that does further
+    terminal\-like or textblock processing\.
+
+    By suppyling the \-info 1 option \- it can return various fields indicating
+    the state of the render\.
+
+    The main 3 are the result, overflow\_right, and unapplied\.
+
+    Renderline handles cursor movements from either keystrokes or ANSI sequences
+    but for a full system the aforementioned loop will need to be in place to
+    manage the set of lines under manipulation\.

+a Tk\-style ordering can be acheived, where punk::args is only handling the

-There are alternative args parsing packages such as:
+For internal functions not requiring features such as solo flags, prefix
+matching, type checking etc \- a well crafted switch statement will be the
+fastest pure\-tcl solution\.
+
+When functions are called often and/or in inner loops, a switch based solution
+generally makes the most sense\. For functions that are part of an API a package
+may be more suitable\.
+
+The following example shows a switch\-based solution that is highly performant
+\(sub microsecond for the no\-args case\)
+
+    proc test1_switch {args} {
+        set opts [dict create\
+            -return "object"\
+            -frametype "heavy"\

+            -show_seps  0\
+            -x a\
+            -y b\
+            -z c\
+            -1 1\
+            -2 2\
+            -3 3\
+        ]
+        foreach {k v} $args {
+            switch -- $k {
+                -return - -show_edge - -show_seps - -frametype - -x - -y - -z - -1 - -2 - -3 {
+                    dict set opts $k $v
+                }
+                default {
+                    error "unrecognised option '$k'. Known options [dict keys $opts]"
+                }
+            }
+        }
+        return $opts
+    }
+
+Note that the switch statement uses literals so that the compiler produces a
+jump\-table for best performance\.
+
+Attempting to build the switch branch using the values from dict keys $opts will
+stop the jump table being built\. To create the faster switch statement without
+repeating the key names, the proc body would need to be built using string map\.
+
+use punk::lib::show\_jump\_tables <procname> to verify that a jump table exists\.

+
+Package to a allow a safe interpreter to access islands of the
+
+filesystem only, i\.e\. restricted directory trees within the
+
+filesystem\. The package brings back file, open and glob to the child interp
+
+interpreter, though in a restricted manner\.
+
+JN Warning:
+
+This mechanism can have interactions with package loading from auto\_path \- needs
+review\.

+  - <a name='1'></a>__add__ *child* *path*
+
+    Add a path to the list of paths that are explicitely allowed for access
+
+    to a child interpreter\. Access to any path that has not been explicitely
+
+    allowed will be denied\. Paths that are added to the list of allowed
+
+    islands are always fully normalized\.
+
+    Arguments:
+
+      * string *child*
+
+        Identifier of the child interpreter to control
+
+  - <a name='2'></a>__reset__ *child*
+
+    Remove all access path allowance and arrange for the interpreter to be
+
+    able to return to the regular safe state\.
+
+    Arguments:
+
+      * string *child*

+
+  - <a name='3'></a>__Allowed__ *child* *fname*
+
+    Check that the file name passed as an argument is within the islands of
+
+    the filesystem that have been registered through the add command for a
+
+    given \(safe\) interpreter\. The path is fully normalized before testing
+
+    against the islands, which themselves are fully normalized\.
+
+    Arguments:
+
+      * string *child*
+
+        Identifier of the child interpreter
+
+      * string *fname*
+
+        \(relative\) path to the file to test
+
+  - <a name='4'></a>__File__ *child* *cmd* *args*
+
+    Parses the options and arguments to the file command to discover which
+
+    paths it tries to access and only return the results of its execution
+
+    when these path are within the allowed islands of the filesystem\.
+
+    Arguments:
+
+      * string *child*
+
+        Identifier of the child interpreter
+
+      * string *cmd*
+
+        Subcommand of the file command
+
+      * string *args*
+
+        Arguments to the file subcommand
+
+  - <a name='5'></a>__Open__ *child* *args*
+
+    Parses the options and arguments to the open command to discover which
+
+    paths it tries to access and only return the results of its execution
+
+    when these path are within the allowed islands of the filesystem\.
+
+    Arguments:
+
+      * string *child*
+
+        Identifier of the child interpreter
+
+      * string *args*
+
+        Arguments to the open subcommand
+
+  - <a name='6'></a>__Expose__ *child* *cmd* *args*
+
+    This procedure allows to callback a command that would typically have
+
+    been hidden from a child interpreter\. It does not "interp expose" but
+
+    rather calls the hidden command, so we can easily revert back\.
+
+    Arguments:
+
+      * string *child*
+
+        Identifier of the child interpreter
+
+      * string *cmd*
+
+        Hidden command to call
+
+      * string *args*
+
+        Arguments to the command
+
+  - <a name='7'></a>__Glob__ *child* *args*
+
+    Parses the options and arguments to the glob command to discover which
+
+    paths it tries to access and only return the results of its execution
+
+    when these path are within the allowed islands of the filesystem\.
+
+    Arguments:
+
+      * string *child*
+
+        Identifier of the child interpreter
+
+      * string *args*
+
+        Arguments to the glob command
+
+  - <a name='8'></a>__Init__ *child*
+
+    Initialise child interpreter so that it will be able to perform some
+
+    file operations, but only within some islands of the filesystem\.
+
+    Arguments:
+
+      * string *child*
+
+        Identifier of the child interpreter

+<dd><p>renderline is the core engine for overtype string processing (frames &amp; textblocks), and the raw mode commandline repl for the Tcl Punk Shell</p>
+<p>It is also a central part of an ansi (micro) virtual terminal-emulator of sorts</p>
+<p>This system does a half decent job at rendering 90's ANSI art to manipulable colour text blocks that can be joined &amp; framed for layout display within a unix or windows terminal</p>
+<p>Renderline helps maintain ANSI text styling reset/replay codes so that the styling of one block doesn't affect another.</p>
+<p>Calling on the punk::ansi library - it can coalesce codes to keep the size down.</p>
+<p>It is a giant mess of doing exactly what common wisdom says not to do... lots at once.</p>
+<p>renderline is part of the Unicode and ANSI aware Overtype system which 'renders' a block of text onto a static underlay</p>
+<p>The underlay is generally expected to be an ordered set of lines or a rectangular text block analogous to a terminal screen - but it can also be ragged in line length, or just blank.</p>
+<p>The overlay couuld be similar - in which case it may often be used to overwrite a column or section of the underlay.</p>
+<p>The overlay could however be a sequence of ANSI-laden text that jumps all over the place.</p>
+<p>renderline itself only deals with a single line - or sometimes a single character.  It is generally called from a loop that does further terminal-like or textblock processing.</p>
+<p>By suppyling the -info 1 option - it can return various fields indicating the state of the render.</p>
+<p>The main 3 are the result, overflow_right, and unapplied.</p>
+<p>Renderline handles cursor movements from either keystrokes or ANSI sequences but for a full system the aforementioned loop will need to be in place to manage the set of lines under manipulation.</p></dd>

+e.g  who is to know that 'Rabbit Paws', 'Forbidden Thrill' and 'Tarsier' refer to a particular shade of pinky-red? (code 95)
+Perhaps it's an indication that colour naming once we get to 256 colours or more is a fool's errand anyway.
+The xterm names are boringly unimaginative - and also have some oddities such as:
+ DarkSlateGray1 which looks much more like cyan..
+ The greyxx names are spelt with an e - but the darkslategrayX variants use an a. Perhaps that's because they are more cyan than grey and the a is a hint?

+<p>When functions are called often and/or in inner loops, a switch based solution generally makes the most sense.
+For functions that are part of an API a package may be more suitable.</p>
+<p>The following example shows a switch-based solution that is highly performant (sub microsecond for the no-args case)</p>

+<p>Note that the switch statement uses literals so that the compiler produces a jump-table for best performance.</p>
+<p>Attempting to build the switch branch using the values from dict keys $opts will stop the jump table being built.
+      To create the faster switch statement without repeating the key names, the proc body would need to be built using string map.</p>
