Compiler Options
Warn on lines modified by DEFINE
Shows lines modified by DEFINE as a warning to help ensure the result of build is as expected. Unchecking this will still annotate as info, but will not remind you as part of output in console on compile.
Annotation
Compiler output
Clear console on Compile
With this option enabled, the contents of the Console will be cleared automatically when you click Generate Payload. Scroll back / history will be kept.
Delete console history on compile
With this option enabled, the contents and history of the Console will be deleted automatically when you click Generate Payload.
Show detailed payload memory usage
Shows a more specific breakdown of byte usage in your payload to help you optimize and plan around any scenario
Detailed Payload Memory Usage Compiler Output
Show remaining payload memory below editor
Shows the remaining available payload memory below the main editor.
**Requires**** ****`Live Error Checking`**** ****to be enabled.**
Remaining payload memory indicator pinned to bottom left of the editor
Show info, error and warning counts above editor
Shows DuckyScript compiler info, error and warning counts above editor. Provides shortcuts to step through each in the payload.
info, error and warning count pinned to top right of the editor
Set editor to read only on compile
With this option enabled, clicking the Generate Payload button will set the editor to Read only to prevent any further accidental changes (temporarily) ensuring the inject.bin will match the editor.
Toggle editor from Read Only to Editing by clicking the label or icon pinned to the top right above the editor
Read Only Mode
Editing Mode
Download inject.bin on successful compile
With this option enabled, after successfully compiling a payload, PayloadStudio will automatically prompt you to download/save the inject.bin
Download payload source on successful compile
With this option enabled, after successfully compiling a payload, PayloadStudio will automatically prompt you to download/save the DuckyScript payload used to compile the inject.bin
Syntax / Version Control
Lock compiler version to DuckyScript Version 1.0
This will lock DuckyScript compiler compatibility to version 1.0 syntax and behavior only.\
Incompatible DuckyScript 1.0 Syntax Errror annotation
Treat STRING blocks as HEREDOC
Checking this box will prevent the compiler from stripping indentation tabs from text inside a STRING block.
This is provided as a fallback for formatting ascii art - because why not?
Allow DEPRECATED DuckyScript 1.0 Fallback Syntax
Recommended Setting: Disabled/Unchecked (
) **DEPRECATED SYNTAX**
Allow deprecated original DuckyScript 1.0 Syntax/Behavior: lines that don’t match any other syntax will encode the first word or first character.
&#xNAN;This is provided only as a compatibility option for old payloads that took advantage of this side affect.
Error thrown with option disabled
RECOMMENDED
Warning thrown with option disabled
NOT RECOMMENDEDAllow implicit modifiers in key combos
Recommended Setting: Disabled/Unchecked (
) **DEPRECATED SYNTAX**
Allow deprecated original DuckyScript 1.0 Syntax/Behavior:
&#xNAN;Example: ‘CONTROL S’ is implicitly CONTROL SHIFT s because S is SHIFT + s
Error thrown with option disabled
RECOMMENDED
Warning thrown with option disabled
NOT RECOMMENDEDCompiler Settings > DuckyScript Optimizations
Optimize DELAY encoding
Forces compiler to use the most efficient DELAY encoding. Giving you more space in your payload to write other code.
This MAY lock compatibility to Advanced DuckyScript 3.0.
Always use new DELAY encoding
Forces compiler to always use DuckyScript 3.0 DELAY encoding.
This WILL lock compatability to Advanced DuckyScript 3.0.
Optimize repeated injections`*`

For use with Ducky Debugger - With this option enabled, clicking the gutter for a specific line will toggle (create/destroy) a debugging breakpoint for that line
Enable DuckyScript 3.0 breakpoints and debugger
For use with Ducky Debugger
Breakpoint on line 300
Debug builds compile breakpoints
Checking this will include all IDE Breakpoints when generating a debug build.\
Generate Debug inject.bin button
Debug builds convert modifiers and keycombos to STRINGS
Checking this will compile all modifiers and key-combos into PayloadStudio safe STRING commands.
This is useful while debugging directly inside the PayloadStudio Console as it prevents the payload from leaving the browser.
Set editor to read only on debug compile
With this option enabled, clicking the Generate Debug button will set the main editor to Read only to prevent any further accidental changes (temporarily) ensuring the inject.bin will match the editor.
Annotate Payload Memory Usage By Line
Recommended Setting: Disabled/Unchecked (
) **affects performance**
Shows number of bytes it takes to execute each line as an INFO annotation in the main editor.
Payload Memory usage annotation
Annotate Expensive Operations
With this option enabled, expensive operations will be annotated in the main editor.
**Requires:**** ****`Annotate Payload Usage By Line`**** ****to be checked/enabled**
Expensive Operation annotation
Annotate Compiler Parser Details
Recommended Setting: Disabled/Unchecked (
) **affects performance**
With this option enabled, compiler parser info will be annotated per line in the main editor
Compiler Parser annotation
Annotate Pre-Processor Preview
Recommended Setting: Disabled/Unchecked (
)**affects performance**
With this option enabled, each line will be annotated with how the compiler sees it after preprocessing, formatting, etc
Preprocessor preview annotation
Annotate Compiled Bytecode for Injections
Recommended Setting: Disabled/Unchecked (
)**affects performance**
With this option enabled, keystroke injection will show the byte-code generated annotated per line.
Compiled Bytecode for Injections annotation
DuckyScript Compiler Debug Logging
Recommended Setting: Disabled/Unchecked (affects performance)
For use in bug reporting - may cause unstable performance.Enable this to enable DuckyScript Compiler Debug logging in the browser console.
