disx multi-CPU diassembler

disx, by Bruce Tomlin, is an interactive, curses-based (TUI) tracing disassembler for Unix systems, including Linux and MacOS. (It may work on Windows via Cygwin or other means.)

It supports almsot two dozen different (mostly 8-bit) CPUs and variants, including Z80, 6800, 6502, 6809, and so on. It writes a small binary control file that can be committed to version control, along with an ASCII symbol definition file and optional "equate" (for symbols with values outside of the disassembly range) file. It can generate both source code and listing files.

For further information, including a list of all CPUs and variants this supports, see the web site and the documentation.

Branches

• main: Just this README.

• trunk: A git svn import of the [Subversion repo] as of early 2025. This branch is the trunk; the Git tags disx4-* are the tags from that repo, and there are no branches in it.

• doc-markdown: Based on trunk, this adds a README.md that more or less duplicates the project home page and converts disx4.txt to Markdown as USAGE.md and CHANGELOG.md. (It also adds a .gitginore.) This brings the documentation to a state where it's displayed nicely by GitHub/GitLab/etc. It's also used as the base for feature fork branches.

Updating trunk

For details of how git-svn works and conversion/import procedures, see sedoc:git/svn.

To update the trunk branch with the latest commits from the SVN repo, check out this main branch and run the update script. This will set up things and, due to the way that git svn rebase works, switch you to the trunk branch, which does leave you in a convenient position to examine and push the new commits.

update does not unfortunately yet update release tags, but that's a little complex, requiring either svn2git (which has its own problems related to branch naming) or doing some of the extra things that svn2git does but git svn does not directly do.
