Reload: How to make sure type of script function hasn't changed?
|
||||
|
||||
Valgrind: test_vim9_cmd: uses uninitialized var
|
||||
no error for:
|
||||
echo extend([0], ['a', true])
|
||||
like it does for:
|
||||
echo extend([0], ['a'])
|
||||
At script level this does not give an error:
|
||||
echo map([0], (_, v) => [])
|
||||
Or:
|
||||
var l: list<number> = [0]
|
||||
echo map(l, (_, v) => [])

Vim9 - Make everything work:
|
||||
- Expand `=expr` in :next, :argedit, :argadd, :argdelete, :drop
|
||||
- Expand `=expr` in :vimgrep, :vimgrepadd, :lvimgrep, :lvimgrepadd
|
||||
- Expand `=expr` in :mkspell
|
||||
- Unlet with range: "unlet list[a : b]"
|
||||
- Implement "export {one, two three}".
|
||||
- Use "null" for v:null, like true and false? #7495
|
||||
- ISN_CHECKTYPE could use check_argtype()
|
||||
- Using a script variable inside a :def function doesn't work if the variable
|
||||
is inside a block, see Test_nested_function(). Should it work?
|
||||
- give error for variable name:
|
||||
let p = function('NoSuchFunc')
|
||||
- Make closures work better:
|
||||
- Create closure in a loop. Need to make a list of them.
|
||||
- If a :def function is called with a function reference, compile it to get
|
||||
the function type.

- For builtin functions using tv_get_string*() use check_for_string() to be

more strict about the argument type.

- Possible memory leaks in test_vim9_func
|

- Implement :lockvar and :unlockvar. How about local variables? Perhaps only
|

allow this for global variables. Use :final or :const otherwise.
|

- Allow function names that will be script-local to start with lower case
|

letter? Or also require names with s: prefix to use upper case?
|

Also apply this function references "var ref = SomeFunc"

- Support passing v:none to use the default argument value. (#6504)

- Make map() give an error if the resulting type of the first argument is

wrong. Only works if the type is known? Is this slow (need to go over all

items)?
|

- Run the same tests in :def and Vim9 script, like in Test_expr7_not()
|

- Check many more builtin function arguments at compile time.

- make 0 == 'string' fail on the script level, like inside :def.

- eval_expr() call in dbg_parsearg() and debuggy_find()

Improve error checking:
|
||||
- "echo Func()" is an error if Func() does not return anything.
|
||||
Before launch:
|
||||
- compile "skip" argument of searchpair()
|
||||
- compile "expr" and "call" expression of a channel in channel_exe_cmd()?
|
||||
- give an error for "echo Func()" if Func() does not return anything.
|
||||
|
||||
Once Vim9 is stable:
|
||||
- Change the help to prefer Vim9 syntax where appropriate
|
||||
- Use Vim9 for runtime files.
|
||||
PR #7497 for autoload/ccomplete.vim
|
||||
- Add all the error numbers in a good place in documentation.
|
||||
- In the generic eval docs, point out the Vim9 syntax where it differs.
|
||||
Also:
|
||||
- For range: make table of first ASCII character with flag to quickly check if
|
||||
it can be a Vim9 command. E.g. "+" can, but "." can't.
|
||||
|
||||
Also for Vim9:
|
||||
- better implementation for partial and tests for that.
|
||||
- Make "g:imported = Export.exported" work in Vim9 script.
|
||||
- Make Foo.Bar() work to call the dict function. (#5676)
|
||||
- Error in any command in "vim9script" aborts sourcing.
|
||||
- Find a way to test expressions in legacy and Vim9 script without duplication
|
||||
- Test each level of expressions properly, with type checking
|
||||
- Test try/catch and throw better, also nested.
|
||||

Test that return inside try/finally jumps to finally and then returns.

defined.

- import type declaration?

- compile options that are an expression, e.g. "expr:" in 'spellsuggest',

'foldexpr', 'foldtext', 'printexpr', 'diffexpr', 'patchexpr', 'charconvert',
|
||||
'balloonexpr', 'includeexpr', 'indentexpr', 'formatexpr'.

Give an error if compilation fails. (#7625)
|
||||
Use the location where the option was set for deciding whether it's to be

evaluated in Vim9 script context.

|

- implement enum; import enum.

EVAL expr
|

LOADVARARG (varargs idx)
|
||||
Define the keywords and commands to make sure it will be backwards
|

compatible.
|
||||
- Make debugging work - at least per function. Need to recompile a function
|
||||
to step through it line-by-line? Evaluate the stack and variables on the
|
||||
stack?
|
||||
- Make profiling work - Add ISN_PROFILE instructions after every line?

- List commands when 'verbose' is set or :verbose is used.
