Projeto Descrição

4tH is a Forth compiler with a little difference. Instead of the standard Forth engine it features a conventional compiler. 4tH is a very small compiler that can create bytecode, C-embeddable bytecode, standalone executables, but also works fine as a scripting language. It supports about 95% of the ANS Forth CORE wordset and features conditional compilation, pipes, files, assertions, forward declarations, enumerations, structures, suspended execution, recursion, include files, etc. It comes with an RPN calculator, line editor, preprocessor, compiler, decompiler, C-source generator, a virtual machine, and a multitasking environment.

3.62.0

A biblioteca de arquivos agora suporte arquivos de log, análise automatizada de data, LZ77 compactação de arquivos e criação do arquivo CSV.
A última palavra definida pode ser compilada anonimamente. Orientação a objetos agora oferece suporte a métodos regulares. O Sourceforge "Bloco reservado palavras de extensão" foram adicionadas. Otimizadores de peephole novos foram adicionados para o compilador, permitindo cálculos de tempo de compilação automática. exec_4th() pode ser otimizado para GCC usando o compilador mudar - DUSEGCCGOTO. A palavra «SMOVE» foi adicionada.

The library files now support logfiles, automated date parsing, LZ77 file compression and CSV file creation.
The last defined word can be compiled anonymously. Object orientation now supports regular methods. The Sourceforge "Block reserved extension words" were added. New peephole optimizers were added to the compiler, allowing automatic compile time calculations. exec_4th() can be optimized for GCC by using the compiler switch -DUSEGCCGOTO. The word 'SMOVE' was added.

3.61.3

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.

3.61.2

Código específico pode ser executado depois de um 'WHILE' falhou um pouco antes de sair do loop. Strings binárias pode ser marcado individualmente. A biblioteca de arquivos agora suportam UTF-8 para GBK / 2 de conversão (e vice-versa), infix tradução fórmula, a correspondência de padrão string, máquinas de estado finito, as funções de estatística, análise de linha de comando aprimorada e toda a gama de palavras ANS Forth ponto flutuante para ZEN float. O pré-processador suporta agora analisar string com delimitadores personalizadas, as macros dentro de macros, e uma pilha de cadeia. Um motor de Markov e um conversor infix-to-postfix foram adicionados aos exemplos.

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.

3.61.1

Um otimizador peephole foi adicionado. A biblioteca de arquivos agora apoiar um sistema de gerenciamento de banco de dados pequeno, multiplicação número duplo, divisão de número de casal, LaTeX geração do arquivo, e os wordset xchar. PROCURAR agora pode ser usado para reposicionar o arquivo para o final. O 2NIP palavras e [FORCE] foram adicionados. Vários bugs foram corrigidos obscura. Suporte para 64-bit arquitecturas foi grandemente melhorada. No Linux, a compilação é agora encenada. Uma simulação de testes nucleares foi adicionado aos exemplos de pré-processamento.

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.

3.61.0

'DELETE-FILE "As palavras' ENVIRON @ 'e foram adicionados. A biblioteca de arquivos agora suporta a gravação de OpenOffice, KOffice e planilhas do Microsoft XML, algoritmos de ordenação diferentes, a criação de intérpretes de ponto flutuante, GTK-servidor, compatível Forth ponto flutuante de I / O para ZEN float, gráficos bitmap portátil e gráficos de tartaruga. Os arquivos podem agora ser suprimidas e as variáveis de ambiente podem ser consultados. O comprimento símbolo máximo é aumentado para 23 caracteres. Dois programas de planilha minúsculos foram adicionados aos exemplos.
Tags: Stable
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.
