Lua Pandoc Citation Modifier

I'm trying to create a lua noscript that does the following with pandoc and its internal citeproc:

The current input is: \`(MPD; \[@Somereference2020 noparens\])\`

The desired output is: \`(MPD; Somereference, 2020)\` with the correct internal link to citeproc references.

I'm close, but I can't seem to wrangle removing the preceding space before \`noparens\` on the output.

Current output is: \`(MPD; Somereference, 2020 )\`

Note the space after the year which I've been able to debug to being the preceding space before the \`noparens\` (based on the debug output with carrots).

Thanks in advance to the Lua ninja ... Here's the code

function Cite(cite)
for i, citation in ipairs(cite.citations) do
if citation.suffix and pandoc.utils.stringify(citation.suffix):match("noparens") then
-- Debugging: Print the original suffix
print("Original suffix:", pandoc.utils.stringify(citation.suffix))

-- Remove 'noparens' from the suffix
local new_suffix = pandoc.List{}
for _, item in ipairs(citation.suffix) do
if item.t == "Str" then
-- Remove 'noparens' and trim spaces/commas
item.text = item.text:gsub("noparens", ""):gsub("^%s*,%s*", ""):gsub("%s*,%s*$", "")
if item.text ~= "" then
new_suffix:insert(item)
end
else
new_suffix:insert(item)
end
end
citation.suffix = new_suffix

-- Debugging: Print the modified suffix
print("Modified suffix:", pandoc.utils.stringify(citation.suffix))

-- Debugging: Print the original content
print("Original content:", pandoc.utils.stringify(cite.content))

-- Remove 'noparens' and unnecessary parentheses from the content
local new_content = pandoc.List{}
for _, item in ipairs(cite.content) do
if item.t == "Str" then
-- Remove 'noparens' and parentheses
item.text = item.text:gsub("noparens", ""):gsub("%(", ""):gsub("%)", ""):gsub("^%s*,%s*", ""):gsub("%s*,%s*$", "")
end
if item.text ~= "" then
new_content:insert(item)
end
end
cite.content = new_content

-- Debugging: Print the modified content
print("Modified citation: ^" .. pandoc.utils.stringify(cite) .. "^")

return cite
end
end
end

(Garry's Mod) Make noscripted entity always grabbable with Gravity Gun

I'm writing a noscripted entity and need it to be always grabbable with the gravity gun. I tried using the GravGunPickupAllowed entity hook for that, but that didn't work. It can be picked up when the gravity gun is supercharged, presumably because it has a higher weight limit, but I need the entity to be able to be picked up by the regular gravity gun without changing the entity's weight. Is there any way I could do such a thing?

How to compile?

Yes, I know there is luac.exe, but thats not what I need.

I have a lua noscript that uses modules I installed from LuaRocks. How can I compile my noscript so that all required modules are compiled with it, so that anyone can run the compiled code, even without anything lua-related installed?

I genuinely have no idea what I am doing wrong. Having an experience programming in Java, C, Python, Lua seems easy, but I really can't call it properly or make it return a value.

What should I do?

LuaLS annotation: class' cannot have multiple values; {Metric,module}

Hello everyone.

I am writing some internal lua modules, I am trying to annotate it correctly (using LLS standard) as there are various classes and modules but I keep having an error of this type :

ldoc --lls -a -d docs/lua/src/
lua/src/prometheus/metric.lua:14: ?: 'class' cannot have multiple values; {Metric,module}

My IDE (Pycharm) is happy with it however and resolves everything without any issue (with annotation based autocompletion)

In this prometheus/ folder, I have my init.lua file that has the following annotation on top

--- @module prometheus
local prometheus = {}

require("prometheus.metric")

...

In the same folder, I have the metric.lua file that contains the following one

--- A Metric
--- @class Metric
--- @field name string the name of the metric
--- @field value number the value of the metric
--- @field labels table the labels of the metric
Metric = {}

...

I don't understand how there conflict as they are on different files ? I found other example of lua project doing this even on the same file and not having any kind of conflicts.

I have no idea what I am doing wrong ?

Thanks

How do you run busted multiple times, from Lua?

This is a cross-post from an existing GitHub discussion but I wanted to ask here since the other place seemed unlikely to get a reply.

The summary is that from what I can tell, busted cannot be reasonably called from Lua, let alone more than once. And I'm in a situation where I want to run busted several times and certain things with its results. How can I do it?

I'd like to use busted to profile unittests. But variation can cause tests to perform differently across runs (for example a cold cache vs a warm cache).

What I'd like to do is be able to run busted in a while loop that goes something like this

local maximumtries = 10
local counter = 10
local fastesttime = 2^1023

while true do
local before = os.clock()

runbustedsuite() -- The lua equivalent of this terminal call busted --helper spec/minimal_init.lua --output=my_cool_profiler .

local duration = os.clock() - before

if duration < fastesttime then
counter = maximumtries
fastesttime = duration
else
counter = counter - 1
end

if counter == 0 then
break
end
end

In the above example, a run that is the fastest of 10 consecutive runs is considered "probably the best time we're going to get". And then I'd use the profile results of that fastest run.

How can I achieve that easily with busted? I checked around it seems like busted isn't like other testing frameworks where you can call the test suite runner directly with lua.

I tried a real example using this:

local function cleararg()
for key, in pairs(arg) do
if key ~= 0 then
argkey = nil
end
end
end

local function keeparg(caller)
local original = vim.deepcopy(arg)

caller()

for key, value in pairs(original) do
argkey = value
end
end

local function runbustedsuite(runner)
keeparg(function()
cleararg()

arg[1] = "--ignore-lua"
arg[2] = "--helper=spec/minimalinit.lua"
arg3 = "--output=busted.profileusingflamegraph"

runner({ standalone=false })
end)
end

local function main()
local maximumtries = 10
local counter = 10
local fastesttime = 2^1023

while true do
print("running")
local before = os.clock()

local runner = require("busted.runner")
runbustedsuite(runner)
-- NOTE: It looks like for some reason busted forces `runner()` to
-- return an empty table if it is called more than once. Which is
-- weird. So we have to force-remove the module so we can load it from
-- scratch again.
--
package.loaded["busted.runner"] = nil

local duration = os.clock() - before

if duration < fastesttime then
counter = maximumtries
fastesttime = duration
else
counter = counter - 1
end

if counter == 0 then
break
end
end
end

main()

Because runner takes a combination of arg and options, the interface for this gets hacky. And then there's this if loaded then return function() end else loaded = true end that prevents me from calling the runner more than once. I tried to get around it by forcing the file to reload with package.loaded["busted.runner"] = nil but it isn't working just yet.

I've tried a second pass at this where I basically copy the contents of busted.execute and try to do things that way. And that's difficult in entirely separate ways.

Anyway I'm struggling to

achieve the effect I'm looking for. Any advice would be appreciated. Maybe I'm just looking in the wrong place and there's an easy way to do this?

how can i check, if at least 2 of 3 given bools are true?

Hello i have 3 bools (to check, if a coordinate is along the edges of a cube with the given size of 16 units):



local bool_1 = x == 1 or x = 16
local bool_2 = y == 1 or y = 16
local bool_3 = z == 1 or z = 16



how must i setup the if-line to check, if at least 2 of these bool-lines are true?
