pesdump

A dump utility for PES files as used by Brother embroidery machines

This is a no-frills program to parse and dump the content of a PES file as described at https://edutechwiki.unige.ch/en/Embroidery_format_PES with no attempt at converting it into a machine-readable format. The initial impetus was having a file which crashed a Brother Innovis-97E when it was loaded, this appeared (and with the help of this program is now confirmed) to be because it contained pause commands but the ability to compare a troublesome file against a good one would have been useful.

It is written in the style of a conventional "recursive descent" parser, without lookahead but with limited backtracking, and is intentionally naive to allow it to be read and possibly modified by non-specialists. Assume that like most Pascal programs the highest-level elements (i.e. the description of the overall file, the description of the standard header etc.) are at the bottom of this program unit.

Under normal circumstances I'd suggest using the Lazarus IDE to compile this code via the .lpi (Lazarus Project Information) file, but it should also be possible to use FPC (Florian's/Free Pascal Compiler) to compile the .lpr (Lazarus Project) file with no special options. This was originally written for FPC 3.0 (hopefully in a way that made it compatible with v2.6) but as of mid-2024 it has been tested with FPC 3.2.

The principal reference for factual information used while writing this program was from EduTechWiki which is subject to the CC BY-NC-SA Licence. The above document cites Trevor Adams's "Frno7's Wiki" as its major source, this explicitly uses GFDLv1.3 and GPLv3. Trevor Adams cites Linus Torvalds's PesConvert program which is not accompanied by a licence indication but is hosted by kernel.org and as such it is reasonable to assume that the same license (GPLv2 with no "or any later version" clause) is intended to apply. Torvalds cites a PHP script by Robert Heel which is covered by GPLv2 with an "any later version" clause, this indirectly cites Trevor Adams (GPLv3).

Because of this mixed heritage, and taking into account that my use of the EduTechWiki document (hence other cited material) has been restricted to factual information plus some type and field names, and noting that Torvalds omits an explicit license choice, I think it appropriate that this program should be licensed using GPLv3.
