-# SQLite Result Formatting Subsystem
-
-The "resfmt" subsystem is a set of C-language subroutines that work
-together to format the output from an SQLite query.  The output format
-is configurable.  The application can request CSV, or a table, or
-any of several other formats, according to needs.
-
-## 1.0 Overview Of Operation
-
-Suppose `pStmt` is a pointer to an SQLite prepared statement
-(a pointer to an `sqlite3_stmt` object) that has been reset and
-bound and is ready to run.  Then to format the output from this
-prepared statement, use code similar to the following:
-
-> ~~~
-sqlite3_resfmt_spec spec;   /* Formatter spec */
-sqlite3_resfmt *pFmt;       /* Formatter object */
-int errCode;                /* Error code */
-char *zErrMsg;              /* Text error message (optional) */
-
-memset(&spec, 0, sizeof(spec));
-// Additional spec initialization here
-pFmt = sqlite3_resfmt_begin(pStmt, &spec);
-while( SQLITE_ROW==sqlite3_step(pStmt) ){
-  sqlite3_resfmt_row(pFmt, pStmt);
-}
-sqlite3_resfmt_finish(pFmt, &errCode, &zErrMsg);
-// Do something with errcode and zErrMsg
-sqlite3_free(zErrMsg);
-~~~
-
-The `sqlite3_resfmt_spec` structure (defined below) describes the desired
-output format.  The `pFmt` variable is a pointer to an opaque sqlite3_resfmt
-object that maintains the statement of the formatter.
-The pFmt object is used as the first parameter to two other
-routines, `sqlite3_resfmt_row()` and `sqlite3_resfmt_finish()`, and
-is not usable for any other purpose by the caller.  The
-`sqlite3_resfmt_finish()` interface serves as a destructor for
-the pFmt object.
-
-## 2.0 The `sqlite3_resfmt_spec` object
-
-A pointer to an instance of the following structure is the second
-parameter to the `sqlite3_resfmt_begin()` interface.  This structure
-defines how the rules of the statement are to be formatted.
-
-> ~~~
-typedef struct sqlite3_resfmt_spec sqlite3_resfmt_spec;
-struct sqlite3_resfmt_spec {
-  int iVersion;               /* Version number of this structure */
-  int eFormat;                /* Output format */
-  unsigned char bShowCNames;  /* True to show column names */
-  unsigned char eEscMode;     /* How to deal with control characters */
-  unsigned char bQuote;       /* Quote output values as SQL literals */
-  unsigned char bWordWrap;    /* Try to wrap on word boundaries */
-  int mxWidth;                /* Maximum column width in columnar modes */
-  const char *zColumnSep;     /* Alternative column separator */
-  const char *zRowSep;        /* Alternative row separator */
-  const char *zTableName;     /* Output table name */
-  const char *zNull;          /* Rendering of NULL */
-  const char *zFloatFmt;      /* printf-style string for rendering floats */
-  int nWidth;                 /* Number of column width parameters */
-  short int *aWidth;          /* Column widths */
-  char *(*xRender)(void*,sqlite3_value*);                 /* Render a value */
-  ssize_t (*xWrite)(void*,const unsigned char*,ssize_t);  /* Write callback */
-  void *pRenderArg;           /* First argument to the xRender callback */
-  void *pWriteArg;            /* First argument to the xWrite callback */
-  char **pzOutput;            /* Storage location for output string */
-  /* Additional fields may be added in the future */
-};
-~~~
-
-The sqlite3_resfmt_spec object must be fully initialized prior
-to calling `sqlite3_resfmt_begin()` and its value must not change
-by the application until after the corresponding call to
-`sqlite3_resfmt_finish()`.  Note that the result formatter itself
-might change values in the sqlite3_resfmt_spec object as it runs.
-But the application should not try to change or use any fields of
-the sqlite3_resfmt_spec object while the formatter is running.
-
-### 2.1 Structure Version Number
-
-The sqlite3_resfmt_spec.iVersion field must be 1.  Future enhancements to this
-subsystem might add new fields onto the bottom of the sqlite3_resfmt_spec
-object. Those new fields will only be accessible if the iVersion is greater
-than 1. Thus the iVersion field is used to support upgradability.
-
-### 2.2 Output Deposition
-
-The formatted output can either be sent to a callback function
-or accumulated into an output buffer in memory obtained
-from system malloc().  If the sqlite3_resfmt_spec.xWrite column is not NULL,
-then that function is invoked (using sqlite3_resfmt_spec.xWriteArg as its
-first argument) to transmit the formatted output.  Or, if
-sqlite3_resfmt_spec.pzOutput points to a pointer to a character, then that
-pointer is made to point to memory obtained from malloc() that
-contains the complete text of the formatted output.
-
-When `sqlite3_resfmt_begin()` is called,
-one of sqlite3_resfmt_spec.xWrite and sqlite3_resfmt_spec.pzOutput must be
-non-NULL and the other must be NULL.
-
-Output might be generated row by row, on each call to
-`sqlite3_resfmt_row()` or it might be written all at once
-on the final call to `sqlite3_resfmt_finish()`, depending
-on the output format.
-
-### 2.3 Output Format
-
-The sqlite3_resfmt_spec.eFormat field is an integer code that defines the
-specific output format that will be generated.  See the
-output format describes below for additional detail.
-
-### 2.4 Show Column Names
-
-The sqlite3_resfmt_spec.bShowCNames field is a boolean.  If true, then column
-names appear in the output.  If false, column names are omitted.
-
-### 2.5 Control Character Escapes
-
-The sqlite3_resfmt_spec.eEscMode determines how ASCII control characters are
-formatted in the output.  If this value is zero, then the control character
-with value X is displayed as ^Y where Y is X+0x40.  Hence, a
-backspace character (U+0008) is shown as "^H".  This is the default.
-If eEscMode is one, then control characters in the range of U+0001
-through U+001f are mapped into U+2401 through U+241f, respectively.
-If eEscMode is 2, then control characters are output directly, with
-no translation.
-
-The TAB (U+0009), LF (U+000a) and CR-LF (U+000d,U+000a) character
-sequence are always output literally and are not mapped to alternative
-display values, regardless of this setting.
-
-### 2.6 Render output as SQL literals
-
-If the sqlite3_resfmt_spec.bQuote field is non-zero (true), then outputs
-are rendered as SQL literal values.  String are written within `'...'`
-with appropriate escapes.  BLOBs are of the form `x'...'`.  NULL values
-come out as "NULL".
-
-### 2.7 Word Wrapping In Columnar Modes
-
-For output modes that attempt to display equal-width columns, the
-sqlite3_resfmt_spec.bWordWrap boolean determines whether long values
-are broken at word boundaries, or at arbitrary characters.  The
-sqlite3_resfmt_spec.mxWidth determines the maximum width of an output column.
-
-### 2.8 Row and Column Separator Strings
-
-The sqlite3_resfmt_spec.zColumnSep and sqlite3_resfmt_spec.zRowSep strings
-are alternative column and row separator character sequences.  If not
-specified (if these pointers are left as NULL) then appropriate defaults
-are used.
-
-### 2.9 The Output Table Name
-
-The sqlite3_resfmt_spec.zTableName value is the name of the output table
-when the MODE_Insert output mode is used.
-
-### 2.10 The Rendering Of NULL
-
-If a value is NULL and sqlite3_resfmt_spec.xRender() does not exist
-or declines to provide a rendering, then show the NULL using the string
-found in sqlite3_resfmt_spec.zNull.  If zNull is itself a NULL pointer
-then NULL values are rendered as an empty string.
-
-### 2.11 Floating Point Value Format
-
-If a value is a floating-point number other than Infinity or NaN, then
-the value is rendered using the printf-style format given by the
-sqlite3_resfmt_spec.zFloatFmt string.
-
-### 2.12 Column Widths And Alignments
-
-The sqlite3_resfmt_spec.aWidth[] array, if specified, is an array of 
-16-bit signed integers that specify the minimum column width and
-the alignment for all columns in columnar output modes.  Negative
-values mean right-justify.  The
-absolute value is the minimum of the corresponding column.
-These widths are deliberately stored in a 16-bit signed integer
-as no good can come from having column widths greater than 32767.
-
-The sqlite3_resfmt_spec.nWidth field is the number of values in the aWidth[]
-array.  Any column beyond the nWidth-th column are assumed to have
-a minimum width of 0.
-
-### 2.13 Optional Value Rendering Callback
-
-If the sqlite3_resfmt_spec.xRender field is not NULL, then each rendered
-sqlite3_value is first passed to the xRender function, giving it
-an opportunity to render the results.  If xRender chooses to render,
-it should write the rendering into memory obtained from sqlite3_malloc()
-and return a pointer to that memory.  The xRender function can decline
-to render (for example, based on the sqlite3_value_type() or other
-characteristics of the value) in which case it can simply return a
-NULL pointer and the usual default rendering will be used instead.
-
-The result rendering subsystem will take responsibility for the
-returned string and will pass the returned string to sqlite3_free()
-when it has finished with it.
-
-The bQuote and eEscMode settings above become no-ops if the xRender
-routine returns non-NULL.  In other words, the application-supplied
-xRender routine is expected to do its own bQuote and eEscMode processing
-if it chooses to render values.
-
-## 3.0 The `sqlite3_resfmt_begin()` Interface
-
-Invoke the `sqlite3_resfmt_begin(P,S)` interface to begin formatting
-the output of prepared statement P using format specification S.
-This routine returns a pointer to an opaque sqlite3_resfmt object that is
-the current state of the formatter.  The `sqlite3_resfmt_finish()`
-routine is the destructor for the sqlite3_resfmt object and must be called
-to prevent a memory leak.
-
-If an out-of-memory fault occurs while allocating space for the
-sqlite3_resfmt object, then `sqlite3_resfmt_begin()` will return a NULL
-pointer.  The application need not check for this case as the
-other routines that use a pointer to the sqlite3_resfmt object all
-interpret a NULL parameter in place of the sqlite3_resfmt pointer as
-a harmless no-op.
-
-## 4.0 The `sqlite3_resfmt_step()` Interface
-
-Invoke the `sqlite3_resfmt_step(F)` interface for each row
-in the prepared statement that is to be output.
-
-The formatter might choose to output some content as each row
-is processed, or it might accumulate the output and send it all
-at once when `sqlite3_resfmt_finish()` is called.  This is at
-the discretion of the output formatter.  Generally, rows are
-output one-by-one on each call to `sqlite3_resfmt_row()` when the
-output format is such that the row can be computed without knowing
-the value of subsequence, such as in CSV output mode, and
-the output is accumulated and sent all at once in columnar output
-modes where the complete output content is needed to compute column
-widths.
-
-### 5.0 The `sqlite3_resfmt_finish()` Interface
-
-Invoke the `sqlite3_resfmt_finish(F,C,E)` interface to finish
-the formatting.  C is an optional pointer to an integer.  If C
-is not a NULL pointer, then any error code associated with the
-formatting operation is written into *C.  E is an optional pointer
-to a human-readable text error message.  If E is not a NULL pointer,
-then an error message held in memory obtained from sqlite3_malloc()
-is written into *E.  It is the responsibility of the calling
-application to invoke sqlite3_free() on this error message to
-reclaim the space.
-
-If the F argument to `sqlite3_resfmt_finish(F,C,E)` is a NULL pointer,
-then this interface is a harmless no-op.
-
-### 6.0 Output Modes
-
-The result formatter supports a variety of output modes.  The
-set of supported output modes might increase in future versions.
-The following output modes are currently defined:
-
-> ~~~
-#define RESFMT_Line      0 /* One column per line. */
-#define RESFMT_Column    1 /* One record per line in neat columns */
-#define RESFMT_List      2 /* One record per line with a separator */
-#define RESFMT_Html      3 /* Generate an XHTML table */
-#define RESFMT_Insert    4 /* Generate SQL "insert" statements */
-#define RESFMT_Tcl       5 /* Generate ANSI-C or TCL quoted elements */
-#define RESFMT_Csv       6 /* Quote strings, numbers are plain */
-#define RESFMT_Explain   7 /* Like RESFMT_Column, but do not truncate data */
-#define RESFMT_Pretty    8 /* Pretty-print schemas */
-#define RESFMT_EQP       9 /* Converts EXPLAIN QUERY PLAN output into a graph */
-#define RESFMT_Json     10 /* Output JSON */
-#define RESFMT_Markdown 11 /* Markdown formatting */
-#define RESFMT_Table    12 /* MySQL-style table formatting */
-#define RESFMT_Box      13 /* Unicode box-drawing characters */
-#define RESFMT_Count    14 /* Output only a count of the rows of output */
-#define RESFMT_Off      15 /* No query output shown */
-#define RESFMT_ScanExp  16 /* Like RESFMT_Explain, but for ".scanstats vm" */
-#define RESFMT_Www      17 /* Full web-page output */
-~~~
-
-Additional detail about the meaning of each of these output modes
-is pending.
-
-### 7.0 Source Code Files
-
-The SQLite result formatter is implemented in three source code files:
-
-   *  `resfmt.c` &rarr;  The implementation, written in portable C99
-   *  `resfmt.h` &rarr;  A header file defining interfaces
-   *  `resfmt.md` &rarr;  This documentation, in Markdown
-
-To use the SQLite result formatter, include the "`resfmt.h`" header file
-and link the application against the "`resfmt.c`" source file.
