It may not be a bad idea to warn when a panel has duplicate values (xpos, ypos, zpos, etc) that could be conflicting with each other. 99% of the time it's easy to catch when it happens, but it may not hurt to consider

Maximum call stack size exceeded at i.deleteReferences

The server crashes with this error when a file references itself as a #base file and then removes the reference

As described in title. I'm not sure whether this could happen in other situations too. (Issue happens on line 3)

Don't throw a warning because deliberately missing #base files is a comment method for HUD customisation

The message should resemble Cannot find file '${documentSymbol.detail}'

It seems that mod_textures.txt matches VDF so it would be helpful if the extension could support this file and related ones as well.

Docs website is at https://cooolbros.github.io/vscode-vdf/ but there is nothing on it. This issue is a mega issue for anything that needs to be added.

Every vscode-vdf setting should be listed with gifs of behaviour and screenshot examples for formatting.

Other recommended VS Code settings should be listed to improve the experience and compatibility with vscode-vdf, such as:
"editor.autoClosingBrackets": "always", to avoid missing } syntax errors
"editor.formatOnSave": true, to run formatter automatically
"editor.wordBasedSuggestions": "off" because it interferes with vscode-vdf suggestions
"files.associations" to associate branded files to vscode-vdf contributed languages, such as

	"files.associations": {
		"bh_*.txt": "hudanimations"
	},

for budhud, to set files like bh_crosshair_animations.txt to hudanimations

If you have a border in resource/clientscheme.res that references a colour also inside resource/clientscheme.res, then change the file contents so that the location of the colour definition changes, the language server will not update the position of the reference, leading to incorrect reference locations

example:

I don't know the name of [ $someone || $someone ], but there was a part of real file in Left 4 Dead 2 UI defination:

"Resource/UI/Addons.res"
{
    // because in longer languages the button text overlaps the icon, I'm only making it visible for these languages
    "IconBrowseWorkshop" [$english || $spanish || $finnish || $brazilian || $japanese || $korean || $latam || $portuguese || $schinese || $tchinese || $swedish || $thai || $turkish]
    {
        "ControlName"       "ImagePanel"
        "fieldName"         "IconBrowseWorkshop"
        "xpos"              "c-50" [$win32wide]
        "xpos"              "c-100"
        "ypos"              "440" [$win32wide]
        "ypos"              "455"
        "zpos"              "0"
        "wide"              "30" [$win32wide]
        "tall"              "30" [$win32wide]
        "wide"              "15"
        "tall"              "15"
        "scaleImage"        "1"
        "pinCorner"         "0"
        "visible"           "1"
        "enabled"           "1"
        "tabPosition"       "0"
        "image"             "addonsmenu/icon_browse_workshop"
    }
}

It throws an error Unexpected '{'. Expected key.

I guess problem occursined by the label [$english || $spanish || $finnish || $brazilian || $japanese || $korean || $latam || $portuguese || $schinese || $tchinese || $swedish || $thai || $turkish].

• It's Ok: [$english]
• It's Error: [$english || $spanish]

extension version

v4.3.0

RunScriptCode and RunScriptFile in popfiles are likely to reach this limit

These are defined in vgui2\vgui_controls\AnimationController.cpp

They're formatted as so:
SetFont <Panel> <Font variable name> <Font name> <Time>
SetTexture <Panel> <Texture variable name> <Material path> <Time>
SetString <Panel> <String variable name> <String value> <Time>

A of now, using any of these raises an error. Using version 4.3.0.

Example with SetFont:

It is used in hl2_misc_dir.vpk > scripts/hudanimations.txt line 539

The syntax is: StopAnimation <element> <property> <delay>

Squad
{
    TFBot
    {
	    Template	T_TFBot_Giant_Soldier_RocketShotgun
    }
}

is incorrect and should cause a diagnostic, as well as a code action to transform the block into

TFBot
{
	Template	T_TFBot_Giant_Soldier_RocketShotgun
}

This WaveSpawn will never spawn and should cause a diagnostic

WaveSpawn
{
	MaxActive	5
	SpawnCount	10
	...

Is this something which can be fixed? I didn't find an extension-setting which would fit to this situation.

Currently, renaming a document symbol only changes the occurrence in the current file, if the key is declared in #base files, the occurrences in the #base file do not get updated to reflect the new name

When a fieldName does not match the element name, a code action should be provided

I'm not sure if all of the problems listed below are really false detections, but at least some seem to be.

• A lot of values for ControlName used in files inside hl2_misc_dir.vpk and platform_misc_dir.vpk are marked as not valid. Such as URLLabel (used in m0rehud) or CReplayBrowserDetailsPanel (used in ahud).
  
• "textAlignment" "left"/"Left", "northwest", "center-west". The first value is used in many files. The second one has about 10 uses. The last is only used once, so it's very likely a typo.
• "paintborder", "paintbackground" "2". Each is used only twice, so...
• 
• 

[Error - 4:32:04 PM] Request textDocument/documentLink failed.
  Message: Request textDocument/documentLink failed with message: Cannot read properties of undefined (reading 'teamFortress2Folder')
  Code: -32603 

I don't know what exactly triggers this error or if it causes any actual problems, but I've manager to "consistently" trigger the error by switching from file to file quickly enough:

But as far as I can tell, that's not the only scenario for this error to be triggered.

Platform specific events are used in hl2_misc_dir.vpk > scripts/hudanimations.txt line 514

The second event definition for WeaponUsesClips with [$X360] is incorrectly declared as unreachable

I can see that some attributes are supported as screencapped below:

But it would be great if all of them are supported, mostly just to reduce the compulsion of "let's spend 5 seconds to make sure I copy-pasted this right or I typed this right". Feel free to mark this as impossible or improbable if the attribute list proves to be too long to do anything with.
