eval: add v:_null_string

2021-04-09T02:36:20+00:00

Replacement for Vim's test_null_string().
Vim uses it to verify that its codebase handles null strings.
Preparation for the Test_null_list() in patch v8.2.1822.

Use v:_null_string, not non-existent env var, for null string tests.

Mention v:_null_string in id() because id(v:_null_string) returns (nil).

test: update writefile test for invalid list items

2018-06-24T20:22:16+00:00

It validates list items with tv_check_str_on_nr()
to catch invalid types (ex. E745, E805).
If there is an invalid item, it does not write to the file.

eval: Fix error messages from writefile

2017-02-14T17:46:12+00:00

1. When calling writefile(list, fname, []) do not show error message twice.
2. Do not allow file name to be overwritten for writefile([1], 2).
3. Do not show “Can’t open file with an empty name” error after error like 
   “using Float as a String” when type of the second argument is not correct.
4. Do not give multiple error messages and still continue for code like 
   `writefile(["test", [], [], [], "tset"])`.

Note that to fix 4. ideally I need tv_check_str_or_nr which is currently present 
in two PRs: #6114 and #5119. I would want to avoid copying this function into 
a yet another PR.

Ref vim/vim#1476.
