| | | | We're still busted, but on the right track.

| | | | | | | | | | | | | | | This bug was incredibly painful to track down: the one-line fix is to replace 'line' with 'first-line' in the call to 'evaluate' in render-line before recursing. Things that made it challenging: - A high degree of coiling with recursive calls and multiple places of evaluation. - An accidental aliasing in bindings (when rendering the main column in render-line) that masked the underlying bug and made things seem to work most of the time. - Too many fucking arguments to render-line, a maze of twisty line objects all alike.

| | | | | In addition to fixing a segfault, the realization here is that we don't always have a type name. Error messages need to take that into account.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Attempt #3: always create a copy of the bindings before each column/evaluate. The details are fuzzy in my head, but it seemed worth trying. I figured I'd either see the old duplication behavior or everything will work. Instead I'm seeing new problems. commit 7208: 5 5 fake-screen =s s 1 down 1 right expected: | - observed: | | - commit 7210-7212: 5 5 fake-screen =s s 1 down 1 right [define foo] s foo [expand foo] observed: no bindings available when rendering foo expanded commit 7213: 5 5 fake-screen =s s 1 down 1 right [define foo] s foo [expand foo] expected within foo: | - observed within foo: | | - commit 7215: 5 5 fake-screen =s s 1 down 1 right [define foo] s foo [expand foo] observed: no bindings available when rendering foo expanded
* 7214 - undo 7213Kartik Agaram2020-11-072-5/+7
| | | | | | | | | | Turns out even that doesn't work. There are two distinct use cases here: 1. Keeping columns from infecting each other. 2. Expanding function calls. Perhaps ping-ponging between them is a sign I need tests.
* 7213 - redo the bugfix of 7210Kartik Agaram2020-11-072-7/+5
| | | | | | | | It turns out deciding when to initialize the table of bindings is quite a thorny problem in the presence of function calls (since they need their args bound). In time I should probably support a linked list of tables. For now I'll just continue to reuse tables, but perform lookups in reverse order so that the correct binding is always returned.

| | | | | Bug fixed; I had to reinitialize the table of bindings. Interesting debugging experience.

| | | | | | | | Only the final line shows the stack for now. No way to move cursor back up. One bug I'm noticing: creating a screen on one line and then reusing it in a second causes operations to be performed multiple times.

| | | | | | | We can copy non-zero literals only to non-addr non-offset scalars. This change is surprisingly short for the magnitude of the limb I felt myself going out on for it. Surprising that there were no unpleasant discoveries.
