Literal string gets evaluated as Lua code
Hi,
When a Lua string starts with prefix \u, the string is parsed as Lua code. For example:
a="\u9"
Returns the following output:
line 1:2 token recognition error at: '"\u'
line 1:6 token recognition error at: '"\n'
{
"Chunk": {
"body": {
"Block": {
"body": [
{
"Assign": {
"targets": [
{
"Name": {
"id": "a",
"start_char": 0,
"stop_char": 0,
"line": 1
}
}
],
"values": [
{
"Number": {
"n": 9,
"start_char": 5,
"stop_char": 5,
"line": 1
}
}
],
"start_char": 0,
"stop_char": 5,
"line": 1
}
}
],
"start_char": 0,
"stop_char": 5,
"line": 1
}
},
"start_char": 0,
"stop_char": 5,
"line": 1
}
}
Digit 9 is evaluated to Number. I was expecting everything enclosed in quotes to be String.
Is that correct?
Can you test it against master? Or give me a better code sample:
a="\u9" does not compile on Lua 5.4
Hi @boolangery
Here is a valid Lua example:
a="\u{9}"
The input value should be parsed as a UTF-8 value, but py-lua-parser returns the following output:
line 1:2 token recognition error at: '"\u'
line 1:8 token recognition error at: '"\n'
