#define GTS_COMMENTS  "#!"

Set of characters used as comments identifiers in GTS geometric files.

struct GtsFile

struct GtsFile {
  FILE * fp;
  guint line, pos;
  GString * token;
  GtsTokenType type;
  gchar * error;

  guint curline, curpos;
  guint scope, scope_max;
  gint next_token;
  gchar * delimiters;
  gchar * comments;
  gchar * tokens;
};

enum GtsTokenType

typedef enum {
  GTS_NONE   = 1 << 8,
  GTS_INT    = 1 << 9,
  GTS_UINT   = 1 << 10,
  GTS_FLOAT  = 1 << 11,
  GTS_DOUBLE = 1 << 12,
  GTS_STRING = 1 << 13,
  GTS_FILE   = 1 << 14,
  GTS_ERROR  = 1 << 15
} GtsTokenType;

struct GtsFileVariable

struct GtsFileVariable {
  GtsTokenType type;
  gchar name[30];
  gboolean unique;
  gpointer data;
  gboolean set;
  guint line, pos;
};

gts_file_new ()

GtsFile*    gts_file_new                    (FILE *fp);

`fp` :	a file pointer.
Returns :	a new GtsFile.

gts_file_next_token ()

void        gts_file_next_token             (GtsFile *f);

Reads next token from f and updates its token and delim fields.

f : a GtsFile.

gts_file_first_token_after ()

void        gts_file_first_token_after      (GtsFile *f,
                                             GtsTokenType type);

Finds and sets the first token of a type different from type occuring after a token of type type.

`f` :	a GtsFile.
`type` :	a GtsTokenType.

gts_file_assign_start ()

void        gts_file_assign_start           (GtsFile *f,
                                             GtsFileVariable *vars);

Opens a block delimited by braces to read a list of optional arguments specified by vars.

If an error is encountered the error field of f is set.

`f` :	a GtsFile.
`vars` :	a `GTS_NONE` terminated array of GtsFileVariable.

gts_file_assign_next ()

GtsFileVariable* gts_file_assign_next       (GtsFile *f,
                                             GtsFileVariable *vars);

Assigns the next optional argument of vars read from f.

`f` :	a GtsFile.
`vars` :	a `GTS_NONE` terminated array of GtsFileVariable.
Returns :	the variable of `vars` which has been assigned or `NULL` if no variable has been assigned (if an error has been encountered the `error` field of `f` is set).

gts_file_assign_variables ()

void        gts_file_assign_variables       (GtsFile *f,
                                             GtsFileVariable *vars);

Assigns all the variables belonging to vars found in f.

If an error is encountered the error field of f is set.

`f` :	a GtsFile.
`vars` :	an array of GtsFileVariable.

gts_file_variable_error ()

void        gts_file_variable_error         (GtsFile *f,
                                             GtsFileVariable *vars,
                                             const gchar *name,
                                             const gchar *format,
                                             ...);

Sets the error field of f using gts_file_verror().

String name must match one of the variable names in vars.

If variable name has been assigned (using gts_file_assign_variables()) sets the line and pos fields of f to the line and position where it has been assigned.

`f` :	a GtsFile.
`vars` :	an array of GtsFileVariable.
`name` :	the name of a variable in `vars`.
`format` :	the standard sprintf() format string.
`...` :	the parameters to insert into the format string.

gts_file_verror ()

void        gts_file_verror                 (GtsFile *f,
                                             const gchar *format,
                                             va_list args);

Sets the error field of f using g_strdup_vprintf().

This function can be called only once and disables any other operation on f (gts_file_close() excepted).

`f` :	a `GtsFile`.
`format` :	the standard sprintf() format string.
`args` :	the list of parameters to insert into the format string.

gts_file_error ()

void        gts_file_error                  (GtsFile *f,
                                             const gchar *format,
                                             ...);
