My (Desi's) personal library for AutoHotkey 2 https://www.autohotkey.com/.

Download dq.ahk and #Include it near the top of your script:

#Requires AutoHotkey v2.0
#Include "path/to/dq.ahk"

Functions are documented in the script with comments in a standard format. For example:

MyFunction(RequiredArg, OptionalArg1?, OptionalArg2 := "") {
    /*
    Description of what this function does.
    
    RequiredArg    - What this parameter is for, and what it accepts.
    [OptionalArg1] - Optional arguments are shown in [square brackets].
    [OptionalArg2] - ...
    
    Return: 
        What the function returns. If it returns an array or an object with named values, then:
            1. named1  --- The contents of the array index or named value.
            2. named2  --- ...
    
    Examples:
        ; Examples of how to use the function and what it outputs.
    */

    ; ...
}

• ReadableHotkey(KeyName)

  • Replaces Send() hotkey symbols with human-readable key names, e.g. "#^s" to "Win+Ctrl+S".

• ReadableFilename(Filename)

  • Takes a file's full path and returns its basename and parent folder for context, e.g. "C:\Docs\Project7\Notes.txt" to "Project7\Notes.txt".

• Basename(Filename)

  • Returns a file's basename. E.g. "C:\Docs\Project7\Notes.txt" to "Notes.txt".

• FlagTitle(GuiObj)

  • Put a * at the start of the GUI's window title. Usually used to indicate unsaved changes to the current file.

• UnflagTitle(GuiObj)

  • Remove * from the start of the GUI's window title.

• GuiToggleVisibility(GuiObj)

  • Toggles whether a GUI is hidden or not.

• dq_SaveFile(Contents, [Filename, SuggestedName, DialogTitle, FileFilter])

  • Handles both Save and Save As functionality, as well as cases where the user cancels the operation.

• dq_LoadFile([Filename, DialogTitle, FileFilter])

  • Handles file loading with or without a File Select dialog, and handles cases where the user cancels the operation.

• EditWidthFromCols(Cols, [FontName, FontSizePt, Debug])

  • Calculates how wide a multiline Edit control has to be in order to fit n characters of text in one line. AHK already lets us size Edits by number of rows of text, but a matching option to size an Edit by character count is missing.
