SYNTAX ERROR CASES TO HANDLE
|
||
|
|
============================
|
||
|
|
|
||
|
|
This document describes a range of non-obvious syntax error conditions that
|
||
|
|
need to be clearly conveyed in error messages.
|
||
|
|
|
||
|
|
|
||
|
|
1 Unterminated expression preceding a for-loop
|
||
|
|
----------------------------------------------
|
||
|
|
|
||
|
|
1| var x = "Hello, world!"
|
||
|
|
2|
|
||
|
|
3| for i in 0 to:100 step:2 do
|
||
|
|
4| cout put:'Count is {i}'
|
||
|
|
5| end
|
||
|
|
|
||
|
|
The statement separator is missing from the end of line 1. However, no
|
||
|
|
error is detected when the for keyword is encountered due to support for
|
||
|
|
inline for-loops.
|
||
|
|
|
||
|
|
An error is only reported when the do keyword is encountered, as inline
|
||
|
|
for-loop do not use this keyword.
|
||
|
|
|
||
|
|
The compiler should alert the user that they may have forgotten a statement
|
||
|
|
separator at the end of the preceding expression.
