DfmExtractor

[jp-insert-download-block]

A small command line utility which allows you to extract DFM, LFM and FRM forms from executable files compiled by Delphi, Lazarus and CodeTyphon.

This program was made for my private use, but it may also be useful to someone.

When translating one program written in Delphi, I needed DFM forms to make it easier to work with the Poedit program, so I decided to write a small program to extract DFMs.

DfmExtractor version 1.1 [Win 32-bit] (2018.02.28)

Usage: DfmExtractor.exe -i=FILE [-n=NAME] [-idx=X] [-o=FILE] [-e=EXT] [-p=STR] [-a] [-d=DIR] [-l] [-h] [-V] [--home]

Mandatory arguments to long options are mandatory for short options too.
Options are case-sensitive. Options in square brackets are optional.
