| | | | | | | | Bug in code-size check. It costs 18 bytes in the boot sector to load 2 tracks of disk (63KB). At that rate I can load 6 more tracks before I need to perform the drudgery again of recalculating offsets.

| | | | First bugfix in baremetal/shell. Already it's much easier to debug.

* 7739 - baremetal/shell: first draft of loopKartik K. Agaram2021-02-142-62/+237
| | | | | This is quite new and speculative. I tried to list out some potential future tests later when we add 'return'. We'll see how it goes.

| | | | | In the process I found a bug in the Mu compiler. Limitations of just asserting the emitted code but not running it.

| | | | | | Pretty thin; perhaps we should put cursor management in words. But we don't need every node in the list of words to know which word in the list the cursor is at.

| | | | Include a file for commit 7708.
* 7709Kartik K. Agaram2021-02-092-24/+28
| | | | | | | Fix the jarringness in the previous commit. Gap buffers now always occupy the same width on screen regardless of where their cursor is. The price: we sometimes have more whitespace between words. But that is perhaps a good thing.
* 7708 - baremetal/shell: word data structureKartik K. Agaram2021-02-092-1/+786
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Not everything here is tested, but enough that I'm starting to feel confident. We see our first divergence with apps/tile. In apps/tile we render everything, then go back and figure out where to position the cursor. This relies on some low-level smarts and is also quite klunky and complex. In baremetal/shell I plan to do something simpler: maintain a tree of objects where each level knows which sub-object under it has the cursor. Now I can pass in the cursor object to each object, and if it detects that it has the cursor it can recursively figure out which sub-object has the cursor. The bottom-most objects (grapheme stacks) draw the cursor as they render themselves. Single-pass algorithm, draw the cursor as you render, no low-level smarts needed. But there's a divergence. What in apps/tile used to look like this, with a cursor ␣ at the end of the word 'abc': abc␣def ..now looks like this: abc␣ def ..with an extra space. This could cause some jarring 'dancing' as you move the cursor through a list of words.
