I am writing a Frama-C Plugin.
I want to develop a plugin, that sets the value of a local variable. By this idea I try to do the value-analysis afterwards, and then I can analyze the reachablility, path analysis and other things by my second plugin.
Is it possible to set the value of a local variable within a plugin (at the start of a function where I know the name)?
EDIT
I now found out how to make new local variables, how to get the Varinfo of variables and how to create new varinfos. The only missing thing is setting the variable's value.
I started with a code like this:
match kf_cil_fun with
| Cil_types.Definition(a,b) ->
let val_visitor = new value_set_visitor kf in
Visitor.visitFramacFileSameGlobals (val_visitor :> Visitor.frama_c_visitor) (Ast.get());
let old_varinfo = Cil.makeLocalVar a "x" Cil.intType in
let new_varinfo = Cil.makeVarinfo false false "x" Cil.intType in
val_visitor#doStuff old_varinfo new_varinfo;
()
| _ -> ()
where the visitor is a simple visitor with a method doStuff, and the builtin-methods vfile, vglob_aux and vstmt_aux that simply call Cil.DoChildren
method doStuff old_varinfo new_varinfo =
Cil.set_varinfo self#behavior old_varinfo new_varinfo;
Does anyone have an idea of how to set the value of x to 1 (or a fixed other value)? Am I doing the things right?

I have in a global gdscript, and inside i have
var number1 = 0
var number2 = 0,
which normally could be accessed by any gdscript by global.number1 and global.number2.
Then i have a different script with a Dictionary inside that holds some values.
How can i make it work like this(see following):
var dict = {0: {path = "global.number1"}, {1: {path = "global.number2"}}
and then, instead of using several if-statements if i want to expand the number of objects in the dictionary, i can do this:
dict[n].path += 1
I dont really know what are you actually asking, but maybe you forgot to set the path to global in the second script?
Anyway you should clarify what's the question.
I'm currently trying to connect a Lua Script with a GS WebApp. The connection is working but due to my lack of knowledge in GScripting I'm not sure why it isn't saving my data correctly.
In the Lua side I'm just passing in a hard-code a random name and simple numerical userid.
local HttpService = game:GetService("HttpService")
local scriptID = scriptlink
local WebApp
local function updateSpreadSheet ()
local playerData = (scriptID .. "?userid=123&name:Jhon Smith")
WebApp = HttpService:GetAsync(playerData)
end
do
updateSpreadSheet()
end
On the Google Script side i'm only saving the data on the last row and then add the value of the userid and the name.
function doGet(e) {
console.log(e)
// console.log(f)
callName(e.parameter.userid,e.parameter.name);
}
function callName(userid,name) {
// Get the last Row and add the name provided
var sheet = SpreadsheetApp.getActiveSheet();
sheet.getRange(sheet.getLastRow() + 1,1).setValues([userid],[name]);
}
However, the only data the script is saving is the name, bypassing the the userid for reasons I have yet to discover.
setValues() requires a 2D array and range dimensions should correspond to that array. The script is only getting 1 x 1 range and setValues argument is not a 2D array. Fix the syntax or use appendRow
sheet.getRange(sheet.getLastRow() + 1,1,1,2).setValues([[userid,name]]);
//or
sheet.appendRow([userid,name])

I am writing some code where I have multiple dictionaries for my data. The reason being, I have multiple core objects and multiple smaller assets and the user must be able to choose a smaller asset and have some function off in the distance run the code with the parent noted.
An example of one of the dictionaries: (I'm working in ROBLOX Lua 5.1 but the syntax for the problem should be identical)
local data = {
character = workspace.Stores.NPCs.Thom,
name = "Thom", npcId = 9,
npcDialog = workspace.Stores.NPCs.Thom.Dialog
}
local items = {
item1 = {
model = workspace.Stores.Items.Item1.Main,
npcName = "Thom",
}
}
This is my function:
local function function1(item)
if not items[item] and data[items[item[npcName]]] then return false end
end
As you can see, I try to index the dictionary using a key from another dictionary. Usually this is no problem.
local thisIsAVariable = item[item1[npcName]]
but the method I use above tries to index the data dictionary for data that is in the items dictionary.
Without a ton of local variables and clutter, is there a way to do this? I had an idea to wrap the conflicting dictionary reference in a tostring() function to separate them - would that work?
Thank you.
As I see it, your issue is that:
data[items[item[npcName]]]
is looking for data[“Thom”] ... but you do not have such a key in the data table. You have a “name” key that has a “Thom” value. You could reverse the name key and value in the data table. “Thom” = name
I have been using Postman so much and built a lot of useful things in it, but now need to implement one more thing.
Briefly:
Need to create test cases to test a correct records counting for every institution.
Now I handled it like that
Structure:
---------Collection
-------Folder
---Districts(folder)
-some folders with tests
---Colleges(folder)
-some folders with tests
---Schools(folder)
-Principal(Folder with test in Schools folder)
where these requests:
POST: Create a list
where in Tests:
var jList = JSON.parse(responseBody);
postman.setEnvironmentVariable("list_id", jList.data.id);
POST: Add some filters to list
GET: lists/{{list_id}} whete in "Test" code:
```
var allLists = JSON.parse(responseBody);
pm.test("test count", function () {
const value = allLists.data.count;
pm.expect(typeof value === 'number').to.eql(true);
pm.expect(value > 0 && value < 999999).to.eql(true);
}); // I check if the number(made in step№2 in a range we need
```
DELETE: delete this list
I guess I do 'overhead work' adding POST(create a list) and -DELETE endpoints in every folder, can I somehow bring it out to environment or variable and execute it before every POST: Add some filters to list and -DELETE endpoint after that
Something like general BeforeEach and AfterEach
Perhaps can I even bring this(below) out in one place for every separate test?
pm.test("test count", function () {
const value = allLists.data.count;
pm.expect(typeof value === 'number').to.eql(true);
pm.expect(value > 0 && value < 999999).to.eql(true);
});
Here is an example how it looks like if it not difficult, give me a piece of advice! Thanks
I want to declare and initialize integer variable in Decision Table. I created a sample rule in .drl file. It's working fine but i want that rule in drool spreadsheet. Anybody know How to do it?
Sample Rule code.
rule "GoodBye1"
salience 5
when
a : Message(count == 45)
then
System.out.println("-----------------");
int temp = a.getTemplatesFromDba("123");
System.out.println("-Raj--> "+temp);
a.setPriority(temp);
update(a);
end
You'll have to write it in to the Action part of your decision table. Here's one way to do it with a decision table. What suites best for your needs requires a bit more info on the details.
Condition | Action
a : Message |
$param | a.setPrio( a.getTemplate( $param) ); update(a);
--------------------------
count == 45 | "123"
If you need, you can add the System.out.prinln calls in the Action block as well. If you have a lot of operations to execute, it might be better to create a helper function for that.
