dmdul v0.1.3

dmdul v0.1.3

This release improves usability and introduces a more interactive operation mode.

Changes

• Added interactive CLI / REPL support.
• Improved user operation flow.
• Added DUL-style control command handling.
• Added dictionary parsing module.
• Updated CLI behavior and related tests.

• Windows binary build passed.

Binary

• dmdul_windows_amd64_v0.1.3.zip

Example

Start interactive DMDUL：

.\bin\dmdul.exe

Interactive extraction example：

DMDUL> set system D:\temp\oldpro\SYSTEM.DBF;
DMDUL> set data_dir D:\temp\oldpro;
DMDUL> bootstrap;
DMDUL> list user;
DMDUL> list table HR_TEST;
DMDUL> unload table HR_TEST.EMP_INFO;
DMDUL> set data_format csv;
DMDUL> unload user HR_TEST;
DMDUL> exit;

dm.ctl remains an optional enhancement file; if not provided, it will be automatically used if dm.ctl exists in the same directory as SYSTEM.DBF.

bootstrap scans the DBF headers under data_dir and generates control.dul, which records the tablespace number, file number, tablespace name, and data file path. unload table and unload user will generate DDL SQL respectively; the data is exported as INSERT SQL by default; it can also be exported as CSV using set data_format csv;.

dmdul v0.1.2

dmdul v0.1.2

Changes

Improved recognition of hidden TABOBJ / INDEX internal objects.
Added support for low-bit assist id table number handling.
Added page-level sample-row validation for candidate tables.
Reduced the risk of misidentifying ordinary index pages as exportable table data.
Validation
go test ./... passed.
Windows binary build passed.
