A new version of the extensible programming language Seed7, has been released.
See: https://thomasmertes.github.io/Seed7Home

Changelog:

  • The answer concerning scanner functions in the FAQ has been improved.
  • The new library scantoml.s7i with string and file scanner functions for TOML symbols has been added.
  • SHA-3 message digest functions have been added to the msgdigest.s7i library.
  • The new library bzip2.s7i has been added. This library supports the decompression of BZIP2 compressed data.
  • The new library archive.s7i has been added. This library supports opening TAR, CPIO, ZIP, RPM and AR archives. Which archive to open is decided either by magic number or by the file extension.
  • The library zip.s7i has been improved:
    • Support for the compression methods Shrink, Deflate64, bzip2, LZMA, Zstandard and XZ has been added.
    • Support for references to existing files in the archive (identified with compression method 92) has been added.
    • When opening a ZIP archive the ZIP magic is checked.
    • Constants for compression methods and extra field IDs have been introduced.
    • Corrupt extra fields are ignored now and the function writeExtraField() has been improved.
    • Now the functions inflate() and inflate64() are invoked with the file as parameter. This saves memory if the comressed data is huge.
    • The functions initializeFileReferenceMap, getReferencePaths, lzwDecompressShrink, getReference and readDataDescriptor have been added.
    • The write permission obtained with getFileMode() when the host system is DOS have been changed.
  • The tar7 example program has been improved:
    • Support to list, extract and create ZIP, RPM, CPIO and AR archives has been added.
    • Support to list and extract BZIP2 compressed TAR archives has been added.
  • Support for the enhanced deflate (deflate64) compression has been added to the library inflate.s7i.
  • In inflate.s7i the functions decodeLength and decodeDistance have been refactored.
  • In deflate.s7i the function deflateBlock() has been refactored and renamed to deflate(). The function deflate() now creates multiple deflate blocks. Calls of deflateBlock() in gzip.s7i have been adjusted.
  • The function lzwDecompressShrink has been added to the library lzw.s7i.
  • The decompression functions in lzw.s7i have been improved to use fixed size arrays.
  • In bitdata.s7i the function eof() has been added for the types lsbInBitStream and msbInBitStream.
  • In bitdata.s7i the performance of getBits(msbInBitStream) has been improved by 20% and the performance of getBits(lsbInBitStream) has been improved by 15%.
  • In chkbitdata.sd7 tests for getBit() and getBits() have been improved and tests for bit-stream eof() have been added.
  • In chktime.sd7 tests for the string to time conversion have been added.
  • The new test program chktoml.sd7, with tests for the TOML scanner functions, has been added.
  • Support for the CRC-32 cyclic redundancy check of BZIP2 has been added to the library crc32.s7i.
  • In magic.s7i support for MAGIC_BZIP2 has been added to the function getMagic.
  • The library tar.s7i has been improved to process UTF-8 paths only if TAR_MAGIC is okay.
  • The library tar_cmds.s7i has been improved to support listing, extracting and creating ZIP, RPM, CPIO and AR archives.
  • Support to list and extract BZIP2 compressed TAR archives has been added to tar_cmds.s7i.
  • The library rpm.s7i has been improved to support a BZIP2 compressed payload.
  • In rpm.s7i the function readLead() has been improved to check if packageType is in the allowed range.
  • The function xzDecompress has been added to the xz.s7i library.
  • The function zstdDecompress has been added to the zstd.s7i library.
  • The function lzmaDecompress has been added to the lzma.s7i library.
  • The library gif.s7i has been improved to read past unknown extension blocks.
  • The library jpeg.s7i has been improved to ignore a superfluous restart marker after the last ECS segment.
  • The library png.s7i has been improved to only raise RANGE_ERROR if the CRC of a critical chunk is incorrect.
  • The json.s7i library has been improved:
    • A for-each-loop which loops over the keys has been added.
    • A for-each-loop which loops over keys and values has been added.
    • Functions to create a JSON object have been added.
  • In scanjson.s7i the function getJsonString has been refactored.
  • In chkjson.sd7 the tests of getJsonString() and getJsonNumber() have been refactored. Tests for getJsonNumber() have been added.
  • Tests for JSON strings with \u parts have been added to chkjson.sd7.
  • The function createMsbHuffmanDecoder with codeLengths parameter has been added to the library huffman.s7i.
  • In huffman.s7i the function createMsbHuffmanDecoder has been refactored to use a for-loop with a repeat count. The unused local variable currentCode has been removed.
  • In ccittfax.s7i the function addCode(msbHuffmanDecoder, ...) has been refactored to use a for-loop with a repeat count.
  • The functions ceil() and floor() have been moved from the math.s7i library to the float.s7i library.
  • The function round10() has been added to the float.s7i library.
  • The library httpserv.s7i has been improved to leave the loop which reads the HTTP header after the double CR LF sequence.
  • The config value WITH_RTL_ARRAY_CAPACITY has been added to the library cc_conf.s7i and to the programs confval.sd7 and s7c.sd7.

  • The documentation of the exp operator in float.s7i has been improved.
  • The documentation of the bin64 conversion functions in bin64.s7i has been improved.
  • The documentation of the mode parameter in file open functions has been improved.
  • The Seed7 compiler (s7c.sd7) has been improved:
    • Special cases of string append (&:=) now use the functions strAppendChMult() and strAppendZeroMult().
    • Optimizations for bytes2Int(aString, SIGNED, BE) and bytes2Int(aString, SIGNED, LE) have been added.
    • In arr_act.s7i the function process (ARR_IDX, ...) has been improved to avoid subtracting minIdx if it is zero.
  • Tests for string append with the mult operator (e.g.: stri &:= "x" mult n;) have been added to chkstr.sd7.

  • In graph.s7i the deprecated function DRAW_FLUSH() has been removed. The function flushGraphic() should be used instead.
  • In graph.s7i the deprecated function setCloseAction() has been removed. Instead of setCloseAction(popupWindow, RETURN_KEY); the statement selectInput(popupWindow, KEY_CLOSE, TRUE); should be used.
  • In draw.s7i the deprecated put() functions with PSET and XOR parameter have been removed. The functions without PSET respectively XOR should be used instead.
  • Support for the action DRW_SET_CLOSE_ACTION has been removed from interpreter and compiler.

  • In drw_emc.c the function reloadPage has been changed to wait for a quarter of a second.
  • The functions strAppendChMult() and strAppendZeroMult() have been added to str_rtl.c.
  • Documentation comments have been improved in bigint.s7i, bigrat.s7i, clib_file.s7i, external_file.s7i, float.s7i, ftp.s7i, huffman.s7i, integer.s7i, json.s7i, lzma.s7i, lzw.s7i, tar_cmds.s7i, fillib.c and fil_rtl.c.
