SevenuP

A ZX Spectrum graphic editor by Jaime Tejedor Gómez (Metalbrain), written in C++ against wxWidgets.

Upstream homepage, with source and binary packages: https://metalbrain.speccy.org/

This repository carries the original source forward to a compiler and a wxWidgets that exist today, on macOS. The upstream code stops at 2009 and does not build against wxWidgets 3.

README.TXT is the author's own documentation and is preserved untouched. Its build instructions describe wxWidgets 2.4/2.6/2.8 and no longer match this tree; use the instructions below instead.

Building on macOS

brew install wxwidgets
cd SRC
make -f makefile.osx

That produces SRC/SevenuP.app. Built and run against wxWidgets 3.3.3 on macOS 26 (Apple silicon). The build is clean; the remaining warnings are deprecations (wxPen/wxBrush style constants, sprintf).

wx-config must be on PATH. For a wxWidgets installed elsewhere:

make -f makefile.osx WX_CONFIG=/path/to/wx-config

The bundle is ad-hoc signed by the makefile, because unsigned binaries are killed on launch on Apple silicon.

Other platforms

makefile.unx, makefile.gcc, makefile.g95, makefile.freebsd and compileSevenuPFreeBSD are upstream files, left as they were shipped. They have not been touched or tested here, and they carry the same wxWidgets 3 incompatibilities that makefile.osx needed fixing for.

What it does

Edits ZX Spectrum graphics under the machine's attribute constraints: 8x8 character cells, one ink and one paper colour per cell, bright and flash flags. Menus for fills, effects, masks, sprite frames, grid and zoom.

• Opens and saves .sev (SevenuP's own format) and .scr (6912-byte screen memory dump)
• Imports images (BMP, GIF, JPG, PNG, PCX, TIF, IFF, XPM) and raw binary
• Exports images (PNG, BMP, JPG, PCX, TIF, XPM)
• Exports data as raw binary, ASM source or C source

Repository lineage

The history is ordered so that upstream releases come first and unmodified, and every later commit is a change this repository makes.

1. Import SevenuP 1.20 source — the 1.20 release, extracted verbatim
2. Import SevenuP 1.21 WIP source — the unfinished work-in-progress release, extracted verbatim
3. Fix two defects left behind by the unfinished 1.21 refactor — first non-upstream commit
4. Ignore build output
5. Build against wxWidgets 3 on macOS
6. Open files double-clicked in the Finder
7. Add LICENSE so the GPL is detected

Both import commits are byte-for-byte identical to the published archives, CRLF line endings included. core.autocrlf is off in this repository so they stay that way.

• 1.20: https://metalbrain.speccy.org/SevenuP-v1.20-src.zip
• 1.21 WIP: https://metalbrain.speccy.org/SevenuP-v1.21src_WIP.zip

What 1.21 WIP was

Its entire changelog entry reads:

2009-??-??: Version 1.21 (Work In Progress)
    (Source) Fixed Unicode compilation and also fixed gcc 4.1 compilation
        problems. Welcome Ubuntu users!

It is a build-fix branch for its own era, not a feature release, and it was never finished. It does not help with wxWidgets 3: the API removals that break the build here postdate it, and it is carried as the base only because it is the author's latest published source.

What this repository changes

In short: two defects 1.21 left mid-refactor, wxWidgets 3 compatibility, and Finder double-click support. CHANGELOG.md has the detail.

Note that CHANGELOG.md covers only this repository's changes. The program's own version history, 2002 to 2009, is in SevenuP.txt under "Version History", written by the author and left untouched.

License

SevenuP is © 2002–2007 Jaime Tejedor Gómez, aka Metalbrain.

Licensed under the GPL, version 2 or later, as granted by the header of every source file. Copyright and licence belong to the author; this repository only carries the source forward and claims nothing over it.

The two upstream statements disagree on the end year: every source file header says 2002–2007, while the "Legal" section of SevenuP.txt still says 2002–2006, not having been updated when 1.21 bumped the headers. The later range is used above.

LICENSE is a byte-identical copy of the GNU-GPL License.txt the project has always shipped, added under a name GitHub's licence detection recognises. It is the 1991 printing of the GPL: the only differences from the text the FSF publishes today are the old postal address, the pre-1999 "Library" (now "Lesser") GPL naming, and whitespace.
