pg_hexedit VS HexManiacAdvance

I am the author of a tool that generates wxHexEditor tags and annotations for Postgres relation files -- pg_hexedit:

I've invested quite a lot of effort in it, and it would be nice to have support for multiple hex editors. That was anticipated to some degree:

I understand why you favor a declarative template format for describing files with tags -- that probably scales really nicely. What I'm doing is pretty grotty, but works surprisingly well in practice. I procedurally generate a description of each file in a shell script, and then open the file in wxHexEditor. I'm generating huge XML files, which is slow, but there are simple workarounds to get acceptable performance.

wxHexEditor doesn't support declarative tags. But even if it did I might not want to use them; the on-disk format of PostgreSQL is much more complicated than most file formats, and isn't supposed to be consumed by third party tools. Writing a C program that uses the struct definitions from the server itself makes the complexity quite manageable -- the tool is basically feature complete, even though I haven't spent a huge amount of time on it.

That said, it would be great if I could adapt pg_hexedit to a hex editor that had some kind of "best of both worlds" support for tags - tags that can be generated lazily and on-demand, when a portion of the file needs to be drawn or redrawn. This would be easy to adapt to -- Postgres relation files always consist of a series of 8KiB blocks/pages. My tool can easily generate tags for any single block without knowing any special context or having any expensive-to-generate state -- I just need a block number (i.e. an 8KiB-aligned byte offset).

HexManiacAdvance 0.5.2

HMA is a binary rom hacking tool for Gen 3 that I've been working on for a few years now. In version 0.5, I added a prototype for a map editor with the goal of replacing AdvanceMap.

HMA just released version 0.5.2, which can do many of the same things that AdvanceMap/XSE/PGE can do, but all within a single tool.

You can always see what changes are new on the releases page. Here's what that page says about v0.4.5:

Just to highjack this post a bit, I'll repeat something a few other people have said below... if you want to hack Gen3, you really can replace pretty much every tool on this list with [HexManiacAdvance](https://github.com/haven1433/HexManiacAdvance). Someone recently competed in the MAGM6 hacking competition and managed to get 3rd place overall using only HexManiacAdvance and AdvanceMap. You don't need any other script editor, trainer editor, text editor, image editor, pokemon editor, move editor, hex editor, or patcher - HMA can literally do it all.

Did it by manually changing it in this Hex Editor https://github.com/haven1433/HexManiacAdvance
