Typing `:` to bind a value truncates the project file #509

Closed azmec closed 3 months ago

azmec commented 3 months ago

Expected behavior

When typing a name to bind a value to, lines of code other than the one being typed on should not be mutated.

Actual behavior

When typing a name to bind a value to, the file is truncated up to an unrelated line of code.

  1. Copy and past the below code into a Wordplay project. 
    
currentTime: Time(relative: ⊥)
oldTime: currentTime

g: Group(Stack('>') [ Phrase("Current Time (UTC): " + currentTime → '') Phrase("Old Time (UTC): " + oldTime → '') Phrase("Delta: " + ) ])

Stage([g])


2. Below the definition for `oldTime`, type `delta`.
3. Type `:`. Observe that the file has been truncated to the line containing `Phrase("Delta: " + )`.

## Screenshots

Below is a video recording the production of the bug.

Minified test case:

a
b: [
]
'c'

Type : after a and everything after the [ disappears. If there is no new line after the [, this does not happen.
