hrily/bubbletea/examples/nested-sequence is the example to reproduce the bug from the issue and gives the expected output with the fix from this commit: |
| // process nested sequence messages in order | ||
| if sequenceMsg, ok := msg.(sequenceMsg); ok { | ||
| for _, cmd := range sequenceMsg { | ||
| p.Send(cmd()) |
There was a problem hiding this comment.
What if we have deeply nested sequences (3+)? Imagine we have a cmd like:
sequenceMsg: [
sequenceMsg: [
sequenceMsg: [customMsg11, customMsg12],
sequenceMsg: [customMsg21, customMsg22]
]
]
where each Msg represents a cmd and what will be returned after running it.
Doesn't this solution only work for the first two sequences? The outermost sequence is handled by line 363, and then the second sequence is handled here, but the third and fourth sequences (with the customMsg*s) will be done concurrently -- customMsg11 will happen before customMsg12, but customMsg21 could occur before customMsg11, after customMsg11, or after customMsg12. Am I missing something?
