Bug ID: 41119
Summary: vbscript fails to parse
'createobject("wscript.shell").run' statement
Product: Wine
Version: 1.9.16
Hardware: x86
OS: Linux
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: vbscript
Assignee: wine-bugs at winehq.org
Reporter: aihujianfei at qq.com
Distribution: ---
The vbscript file for test is :
createobject("wscript.shell").run "calc.exe"
I see the vbs bison parse file in
https://github.com/alexhenrie/wine/blob/master/dlls/vbscript/parser.y ,
the parse failed at the pos [.run] in this file.
I think the fail reason is there has one confilct .
for more information , I run command [bison -v -d -pparser_ parser.y], then it
generate file parser.output .
In the file parser.output , part of the file show this confilct which mentioned
above .
"
state 160
77 ArgumentList: Expression .
78 | Expression . ',' ArgumentList
85 Expression: Expression . tIMP EqvExpression
138 PrimaryExpression: '(' Expression . ')'
tIMP shift, and go to state 123
',' shift, and go to state 162
')' shift, and go to state 156
')' [reduce using rule 77 (ArgumentList)]
"
As we can see above , there has one shift/reduce conflict . to parse this file
success , we need a reduce to ArgumentList , instead of shift to
PrimaryExpression .
I will appreciate your fix.
