Issue on attach_mappings with Telescope find_files picker - neovim

I try to create a function with the Neovim Telescope plugin and find_files builtin picker to list my configuration files (in ~/.config/nvim/lua directory). But I have an issue to use a specific mapping (here defined with CTRL-e) after selecting an entry via Telescope.
My lua/reload.lua file :
local M = {}
M.reload = function()
local opts = {
prompt_title = 'Configuration files',
cwd = '~/.config/nvim/lua',
attach_mappings = function(_, map)
local action_state = require('telescope.actions.state')
-- Adds a new map to ctrl+e.
map('i', '<C-e>', function(_)
local entry = action_state.get_selected_entry()
local name = get_module_name(entry.value)
print('Name = ' .. name)
return true
end,
}
-- call the builtin method to list files
require('telescope.builtin').find_files(opts)
end
return M
When I call reload method require('reload').reload(), the Telescope find_files picker is open correctly, I can select a file in the list but my CTRL-e mapping does not work => function to print selected filename not called.
Have some clue to help me ?

You will need to press ctr+e before selecting the item in the list.

lua inheritance on existing object

I am writing a new constructor and I have something like this:
function Map:new(path, world, debug)
local map = sti(path, { "box2d" })
return map
end
function Map:update(dt)
print('call this')
end
sti is some thirdparty library that constructs a class object.
What I am trying to do is make it so when I call:
map:update(dt)
it calls the functions I have declared. If not found, it calls the actual function that sti sets up on the object.
I've tried stuffing around with metatables but can't seem to get my functions to take priority over the third party library supplied functions....
Reading the source code for what I believe is the library you're using (Simple-Tiled-Implementation), I figured out it actually overrides your metatable with another one:
local function new(map, plugins, ox, oy)
local dir = ""
if type(map) == "table" then
map = setmetatable(map, Map) -- Here
else
-- Check for valid map type
local ext = map:sub(-4, -1)
assert(ext == ".lua", string.format(
"Invalid file type: %s. File must be of type: lua.",
ext
))
-- Get directory of map
dir = map:reverse():find("[/\\]") or ""
if dir ~= "" then
dir = map:sub(1, 1 + (#map - dir))
end
-- Load map
map = setmetatable(assert(love.filesystem.load(map))(), Map) -- Or here
end
map:init(dir, plugins, ox, oy)
return map
end
The function above is defined here
You'll need to pass a table argument as map instead of the path, there you can define update(), which will take precedence over the metatable provided by STI.
I believe you can copy the procedure STI does to load your map and provide it with a table containing the function you wish to define inside:
-- Check for valid map type
local ext = map:sub(-4, -1)
assert(ext == ".lua", string.format(
"Invalid file type: %s. File must be of type: lua.",
ext
))
-- Get directory of map
dir = map:reverse():find("[/\\]") or ""
if dir ~= "" then
dir = map:sub(1, 1 + (#map - dir))
end
-- Load map
local map = assert(love.filesystem.load(map))()
function map:update()
-- Do things
end
sti(map, { "box2d" })
unfortunately sti declares 'local dir' at the top of the function so copying the code did not work.
I found a solution how ever I have made myself some way to easily set a class as a proxy in lua:
-- forward a function call from oldSelf:fn(...) to newSelf:fn(...)
function utils.forwardFunc(fn, newSelf)
return function(oldSelf, ...)
local function __NULL__() end
return (fn or __NULL__)(newSelf, ...)
end
end
-- make a function fn(...) call newSelf:fn(...)
function utils.func(fn, newSelf)
return function(...)
local function __NULL__() end
return (fn or __NULL__)(newSelf, ...)
end
end
-- forward any undefined functions called on 'from' to 'to'
-- if 'to' is a function, it acts as a dynamic proxy, incase you are changing what class you are proxying to
-- on the fly. For example, a state machine proxies to the current state
function utils.proxyClass(from, to)
local mt = getmetatable(from)
setmetatable(from, {__index = function(_, func)
if mt and mt[func] then
return mt[func]
end
local forwardTo = to
if type(to) == 'function' then
forwardTo = to(from)
end
if type(forwardTo[func]) == 'function' then
return utils.forwardFunc(forwardTo[func], forwardTo)
else
return forwardTo[func]
end
end})
end

Put an object in the inventory with Roblox Studio

When I put an object in the backpack, the Explorer window shows these objects, but the inventory displayed stays empty.
My code :
local objets = game.ServerStorage.aRamasser
local nbMaxObjets = 10
wait(5)
objets.Parent = game.Workspace
for indice,unObjet in pairs(objets:GetChildren()) do
local ClickDetector = unObjet:FindFirstChild("ClickDetector")
ClickDetector.MouseClick :Connect(
function (joueur)
local inventaire = joueur:FindFirstChildOfClass("Backpack")
if inventaire then
local nbObjets = table.getn(inventaire:GetChildren())
if nbObjets < nbMaxObjets then
(unObjet:Clone()).Parent = inventaire
unObjet.Transparency = 1
unObjet.CanCollide = false
wait(15)
unObjet.Transparency = 0
unObjet.CanCollide = true
end
end
end
)
end
Explanation :
The objects are in the directory ServerStorage. At the begining of the game, in the script above (in Workspace), this directory is moved into Workspace. The objects are visible.
Then, if a click is detected on one object, this object is cloned and that clone is put in Backpack. It works, I see them in Explorer. But not in the inventory :
Your object needs to be inside a tool, tool can come in the inventory gui.
local tool = Instance.new("Tool")
tool.Parent = inventaire
(unObjet:Clone()).Parent = tool

How to send errors from Neovim LSP to ALE

ALE has an API for sending errors to it from other sources. I'm using this like shown below and it works for the first error. More specifically, if I make one edit that results in an LSP error, the error will be displayed by ALE in the location list. If I make any further keystrokes, the location list is emptied again.
I can also trigger this behavior if I disable LSP, load ALE, manually call ShowResults and then press any other key in insert mode.
My hypothesis is that ALEs linting in insert mode (per default) kicks in. If LSP is disabled and there are no linters registered for the current file type, it doesn't find any errors (obviously, there's nothing that could report any) and so it empties my location list again. So the steps are: open buffer without LSP, call ShowResults, location list opens, press i, press any key, location list is empty
Now I thought that it was because I wasn't implementing the full ALE API. So I added a hook (2nd snippet). I can verify that this hook is called and that it generates valid messages. If I keep the location list open I can even see all the expected errors flickering across the loclist. I can navigate to those errors with :lolder, but I don't know why ALE always adds another, empty location list, after the LSP is done doing its job.
Or maybe I'm doing something wrong here.
vim.lsp.handlers["textDocument/publishDiagnostics"] = function(_, _, params, client_id, _, config)
local uri = params.uri
local bufnr = vim.uri_to_bufnr(uri)
if not bufnr then

end
local diagnostics = params.diagnostics
if not diagnostics or vim.tbl_isempty(diagnostics) then
vim.fn['ale#other_source#ShowResults'](bufnr, "nvim-lsp", {})
return
end
-- Important so we can pull diagnostics from this table when ALE asks for

msg.bufnr = bufnr
msg.nr = event.severity
table.insert(messages, msg)

Second snippet which is called from the 'on_attach' function of the Neovim LSP
function ALEHook(bufnr)
vim.fn['ale#other_source#StartChecking'](bufnr, "nvim-lsp")
local diagnostics = vim.lsp.diagnostic.get(bufnr, client.id)
if not diagnostics or vim.tbl_isempty(diagnostics) then

Error in save as type using uiputfile - Matlab

In app designer I have two buttons one to declare the working folder:
function setSaveLocationButtonPushed(app, event)
app.path = uigetdir()
end
The other one to save an image
function saveButtonPushed(app, event)
pathSave = app.path;
[file, pathSave] = uiputfile([pathSave,'*.jpg']);
…
end
Why do I get in the save as type also the app.path? (as shown in image)
Your code [pathSave,'*.jpg'] concatenates the path and the filter and then passes the result as the only argument to the uiputfile function. This argument tells the function what file filter to use.
Instead of storing the chosen directory, make it change the current directory. The file selection UI always opens in the current directory.
function setSaveLocationButtonPushed(app, event)
p = uigetdir;
cd(p)
end
function saveButtonPushed(app, event)
[file, pathSave] = uiputfile('*.jpg');
…
end
If you don’t want to change the current directory for the whole application, you can change it just before calling the uiputfile function, and change it back afterward:
function saveButtonPushed(app, event)
p = cd(app.path);
[file, pathSave] = uiputfile('*.jpg');
cd(p);
…
end

Error Saving the Excel File using worksheet.saveas

I have an Excel template file . Based on the Excel version, I would like to SaveAs as Temp.xlsm through Matlab.
Here is the code I am using to save the template file :
if(XLversion >= 12.0)
Workbook = invoke(Excel.Workbooks,'Open',tempxls);
tempxls1 = [pwd '\utils\temp.xlsm'];
Workbook.SaveAs(tempxls1,1);
tempxls = tempxls1;
extn = 'xlsm';
end
The code is working fine. However when I try to open the file, I get the following error :
However, when the save the temp.xls to temp.xlsm through SaveAs menu, it opens without any error.
Any idea what could be the error in the code or If I am missing something.
Thanks
Can you try the following code please and comment. You may call this sub-routine to save the as the file.
Private Sub Workbook_BeforeSave(ByVal SaveAsUI As Boolean, Cancel As Boolean)
Dim FileNameVal As String
If SaveAsUI Then
FileNameVal = Application.GetSaveAsFilename(, "Excel Macro-Enabled Workbook (*.xlsm), *.xlsm")
Cancel = True
If FileNameVal = "False" Then 'User pressed cancel
Exit Sub
End If
Application.EnableEvents = False
If Right(ThisWorkbook.Name, 5) <> ".xlsm" Then
ThisWorkbook.SaveAs Filename:=FileNameVal & ".xlsm", FileFormat:=xlOpenXMLWorkbookMacroEnabled
Else
ThisWorkbook.SaveAs Filename:=FileNameVal, FileFormat:=xlOpenXMLWorkbookMacroEnabled
End If
Application.EnableEvents = True
End If
End Sub
