| 06:09 | I believe this completes the program loader for building a ROM image. There are a few error conditions that are not checked for; for example, segment IDs are not bounds checked. Similarly, it's not checked to see if a BSS segment has a HUNK_TEXT hunk with a non-zero length. However, these should be fairly easy to add later on, should these become problematic inputs to the MakeROM tool. check-in: 675b1e2afa user: kc5tja tags: makerom | |

| 05:27 | Steps towards better support for BSS segments (and, now that I think about it, page protection as well). check-in: c3a23a7120 user: kc5tja tags: makerom | |
| 03:33 | HUNK_RELOC64 support added to load interpreter. Still need to implement support for distinguishing between BSS and CODE/DATA ahead of time, though; otherwise, we'd need two passes through the input file, which I'm not a fan of. check-in: 74b1dabdba user: kc5tja tags: makerom | |
| 01:59 | Import (:delete ...) function in Brickie check-in: 1bc0382449 user: kc5tja tags: makerom | |

| 23:03 | Choose better name for section check-in: 34a0e063d2 user: kc5tja tags: makerom | |
| 20:40 | Inserted a lot of explanation behind why I chose the magic constants that I did. They probably don't belong here. They probably need to reside in a separate reference document. But, at least I have them under revision control somewhere. check-in: 1f7133f0d8 user: kc5tja tags: makerom | |
| 18:50 | Update brickie check-in: da8e336246 user: kc5tja tags: makerom | |
| 18:49 | Introduce doc and code directives to make "weaving" easier. check-in: a28155cb66 user: kc5tja tags: trunk | |
| 18:45 | Rename (:code) to (:bottom), bringing symmetry with (:top), and also allowing me to use (:code) as a tag to identify where code picks up versus documentation. (:code) (which is also invoked implicitly in some other directives) enables outlist generation, while (:doc) disables it. This allows for bulk documentation in, e.g., raw Markdown or HTML to comingle with executable program code. Closed-Leaf check-in: b8c915baf6 user: kc5tja tags: doc-directive | |

| 20:10 | Introducing Brickie, a literate programming tool written for GForth, but it should be portable to DX-Forth with modest effort. It is based on Akkartik's "tangle" tool, and has similar syntax for markup. Brickie is optimized for my project's needs, however, and will evolve independently of Akkartik's work. Long story short, you write software as layers of related functionality: in a sense, you explicitly name and compose patches which ultimately leads to the finished product. This allows for code and commentary to co-reside, even when chunks of related functionality are widely separated in the source code. See http://akkartik.name/post/wart-layers for more behind the theory of this approach to literate programming. check-in: 63fa3ba241 user: kc5tja tags: trunk | |
| 20:00 | Clean up working file if tangle succeeds Closed-Leaf check-in: 9ac2855656 user: kc5tja tags: x-brickie | |
| 19:57 | Added makefile; makes tangle a binary check-in: 3f4f6d01a1 user: kc5tja tags: x-brickie | |
| 19:03 | Add tangle script check-in: ca2352c8b1 user: kc5tja tags: x-brickie | |
| 08:41 | Introduces :before and :after directives. Precise syntax isn't *quite* the same as Akkartik's version, but pretty close. This basically completes Brickie's inner guts. Next up, wrapping this up into a convenient shell-invokable script of some kind. check-in: 16be7efd90 user: kc5tja tags: x-brickie | |
| 07:27 | Evaluate directives as Forth command strings. check-in: b53ea0892d user: kc5tja tags: x-brickie | |
| 06:44 | Introduced an "insertion point" (IP) variable. This tracks where the next line of input will be placed in the output list. Future directives will adjust the insertion point; for example (:before XXX) will look for XXX in the outlist, and if found, will set IP to the immediately preceding line. (:after YYY) will do the same, but sets IP directly to the line containing YYY, so that new text will appear after it. (No facility exists for deletion of code yet; I'm not sure how that works. Need to study akkartik's code to learn more about that.) check-in: 86bd346a6c user: kc5tja tags: x-brickie | |

| 05:51 | Forth instructions to read in a file, line by line. Accumulate the input; directives not yet implemented. Writes output file. check-in: 3192ac7b76 user: kc5tja tags: x-brickie | |
