All releases of 4tH compiler
Release Notes: The library files now support stem-leaf plots, finite difference, compass boxing, HTML and XML character entities, Hamming (7,4) codes, Base64 conversion, FEXPM1, and FLNP1. Preprocessor macros can be undefined with the 'SCRAP:' keyword, and simple flow control was added. PAD size is increased to 768 characters to make pictured numeric output 64-bit compliant. The accuracy of FSINH, FCOSH, FTANH, FASIN, FACOS, and FATAN was significantly improved. The words '[ELSE]' and '[IGNORE]' have been added. Coherent 4.2.x and Android 3.x ports are now available.
Release Notes: Unions and pragmas can be defined. The library files now support several polynomials, RAM disks, menus, bitfields, bit arrays, several new sorting algorithms, Morse signs, and 3VL. The preprocessor was enhanced, supporting S\", token concatenation, string comparison, variable assignment, and smart double number/FP literals. 'DOES>' can be used to change the execution semantics of basic data types. A bug in the Linux Makefile was fixed. Overflow and underflow errors in number conversion were fixed. A bug in the 'IF' statement of 4tsh was fixed. The accuracy of the 'FERF' words was improved.
Release Notes: Specific code can be executed after a failed 'WHILE' just before exiting the loop. Binary strings can be tagged individually. The library files now support UTF-8 to GBK/2 conversion (and vice versa), infix formula translation, string pattern matching, finite state machines, statistical functions, enhanced command line parsing and the full range of ANS Forth floating point words for ZEN float. The preprocessor now supports string parsing with custom delimiters, macros within macros, and a string stack. A Markov engine and an infix-to-postfix converter were added to the examples.
Release Notes: A peephole optimizer was added. The library files now support a tiny database management system, double number multiplication, double number division, LaTeX file generation, and the XCHAR wordset. SEEK can now be used to reposition the file to the end. The words 2NIP and [FORCE] were added. Several obscure bugs were fixed. Support for 64-bit architectures was greatly improved. On Linux, compilation is now staged. A nuclear test simulation was added to the preprocessor examples.
Release Notes: The words ’DELETE-FILE’ and ’ENVIRON@’ have been added. The library files now support writing OpenOffice, KOffice, and Microsoft XML spreadsheets, different sorting algorithms, the creation of floating point interpreters, GTK-server, Forth compatible floating point I/O for ZEN float, portable bitmap graphics and Turtle graphics. Files can now be deleted and environment variables can be queried. The maximum symbol length is increased to 23 characters. Two tiny spreadsheet programs were added to the examples.
Release Notes: The performance of several bytecodes was improved. 'AKA' was enhanced. 'FIELD:' was added. The preprocessor now supports blockfiles, parameters, ANS Forth structures, and 'SYNONYM'. The memory allocation and 'PARSE-NAME' libraries were rewritten. Several new libraries were added, including Soundex support and ARC4 and TEAN encryption. A TinyC interpreter was added to the examples.
Release Notes: Version numbering was changed. The words 'RANDOM' and 'MAX-RAND' have been removed. The word 'RSHIFT' now performs a logical shift. The library files now support several 'state of the art' random number generators, simple hashtables, associative arrays, and strpbrk() and strchr() like words. A tail call optimizer was added to the compiler. A small BASIC interpreter was added to the examples.
Release Notes: The words '[/]' and '[SIGN]' have been added. The preprocessor was expanded and now takes the DIR4TH environment variable into account. The library files now support ANS Forth compatible versions of all floating point input and output words. The library file getenv.4th was rewritten. The library file row.4th was changed. A chapter on library dependencies was added to the manual.
Release Notes: A preprocessor was added. The multitasking environment was rewritten. Several ANS floating point bugs were fixed. Another floating point environment, called Zen float, was added. The Linux version now supports shared libraries. More complex patches are supported. Various other additions and fixes were made to the libraries and examples.
Release Notes: Several bugs in the floating point library were fixed. The circular ring buffer library was rewritten. Many FSL and forth200x words were added to the library. The return value of "OPEN" was standardized. "AS" was removed. "ERROR?" and "BUFFER:" were added. The editor can now export text files. A classic "Startrek" program was added to the examples. New sections were added to the Development Guide.
