Summary: foreach() mis items from list when brackets are
unclosed
Description:
I wanted to read all lines of a file, and iterate on them. But I wasn't same
account of line in my ''foreach()'' as there was in my file. The last iterated
line was like a concatenation of all remaining lines of the file. The cause is
the incorrect item was containing an opening bracket '['.
Steps to Reproduce:
<code cmake>
function(test_list_items _nb_lines _lines)
set(_i 0)
message("-- test '${_lines}'")
# string(REPLACE "]" "" _lines "${_lines}")
# string(REPLACE "[" "" _lines "${_lines}")
foreach (_l IN LISTS _lines)
math(EXPR _i "${_i}+1")
message(" ${_i}: '${_l}'")
endforeach()
if (NOT _i EQUAL ${_nb_lines})
message(" ${_i} != ${_nb_lines}")
else()
message(" OK")
endif()
endfunction()
set(_a "line-1;line-2\;;line-3 // [;line-4")
test_list_items(4 "${_a}")
set(_a "line-1;line-2\;;line-3 // ];line-4")
test_list_items(4 "${_a}")
set(_a "line-1;line-2\; // [;line-3 // ];line-4")
test_list_items(4 "${_a}")
set(_a "line-1;line-2\; // ];line-3 // [;line-4")
test_list_items(4 "${_a}")
set(_a "line-1;line-2\; // {;line-3 // };line-4")
test_list_items(4 "${_a}")
set(_a "line-1;line-2\;;line-3 // {;line-4")
test_list_items(4 "${_a}")
set(_a "line-1;line-2\;;line-3 // };line-4")
test_list_items(4 "${_a}")
</code>
Here is the output:
<code>
-- test 'line-1;line-2\;;line-3 // [;line-4'
1: 'line-1'
2: 'line-2;'
3: 'line-3 // [;line-4'
3 != 4
-- test 'line-1;line-2\;;line-3 // ];line-4'
1: 'line-1'
2: 'line-2;'
3: 'line-3 // ];line-4'
3 != 4
-- test 'line-1;line-2\; // [;line-3 // ];line-4'
1: 'line-1'
2: 'line-2; // [;line-3 // ]'
3: 'line-4'
3 != 4
-- test 'line-1;line-2\; // ];line-3 // [;line-4'
1: 'line-1'
2: 'line-2; // ];line-3 // ['
3: 'line-4'
3 != 4
-- test 'line-1;line-2\; // {;line-3 // };line-4'
1: 'line-1'
2: 'line-2; // {'
3: 'line-3 // }'
4: 'line-4'
OK
-- test 'line-1;line-2\;;line-3 // {;line-4'
1: 'line-1'
2: 'line-2;'
3: 'line-3 // {'
4: 'line-4'
OK
-- test 'line-1;line-2\;;line-3 // };line-4'
1: 'line-1'
2: 'line-2;'
3: 'line-3 // }'
4: 'line-4'
OK
</code>
Additional Information:
The only workaround I found is to add these transformation before the
''foreach()'':
<code cmake>
string(REPLACE "]" "" _lines "${_lines}")
string(REPLACE "[" "" _lines "${_lines}")
