Function Documentation

static dlisp_lispentry* alloc_lispentry (  FILE *  f  )  [static]

allocate lisp entry structure.

dlisp_lispentry* dlisp_read_lisp_bracket (  FILE *  f  )

Read inside bracket of lisp string. Read from a file stream, and return a dlisp_lispentry structure parsing the lisp construct. Returns: dlisp_lispentry Parameters: f  Input file stream

dlisp_lispentry* dlisp_read_lisp_text (  FILE *  f  )

read a string of lisp text, with many brackets, and create a tree representation of it. Returns: dlisp_lispentry structure filled with parsed lisp data. Parameters: f  Input file stream

static int force_read_char (  FILE *  f, int  want_char, const char *  accept_char )  [static]

Force-read char, and give error. Parameters: accept_char  can be null

static void lisp_error (  FILE *  f, const char *  sentence )  [static]

generate an error, and exit. Noting the current character position Parameters: f  input file stream sentence  error message

static int peek_char (  FILE *  f  )  [static]

peek one character, taking comments in consideration.

static int peek_char_raw (  FILE *  f  )  [static]

peek one character, only for read_noncomment_char

static dlisp_lispentry* read_lisp_entity (  FILE *  f  )  [static]

read a entity. entity -> lisp-bracket | term lisp-bracket -> (entity*)

static char* read_lisp_name (  FILE *  f, const char *  terminatorstring )  [static]

read lisp symbol, delimited by terminatorstring. escape is done with "\" current buffer position previous char, used for checking \

static int read_noncomment_char (  FILE *  f  )  [static]

read a new character, excluding comments.

static void skip_spaces (  FILE *  f  )  [static]

skip space, ignoring comments.

static void skip_to_comment_terminator (  FILE *  f  )  [static]

Multi-line comment procedure. skip to !#

static void skip_to_newline (  FILE *  f  )  [static]
