Tools

Useful tools that didn't really fit anywhere else

The Tools View simply contains various different tools and niche helpers that didn't fit anywhere else in the Editor.

All tools can be detacted and used as their own windows by simply closing them first and then dragging its header off of the tools window. The tool will automatically return to the tools window when it's being closed.

This view takes a mangled type name from one of the following encoding standards and turns it back into the actual type name used in the respective programming language.

Itanium (Mangling used by GCC and Clang in C++)
MSVC
Rust
D-Lang

To decmangle a string, simply enter it in the text field at the top and the demangled version of it will be displayed in the text field below.

The regex replacer tool takes a input regex pattern and applies a regex replace operation on it.

The regex pattern field can contain any standard compliant regex pattern. For more information in this, consult the Regex cheatsheet.

The following replace pattern syntax is permitted:

Characters	Replacement
$n	n-th backreference (i.e., a copy of the n-th matched group specified with parentheses in the regex pattern). n must be an integer value designating a valid backreference, greater than 0, and of two digits at most.
$&	A copy of the entire match
$`	The prefix (i.e., the part of the target sequence that precedes the match).
$´	The suffix (i.e., the part of the target sequence that follows the match).
$$	A single $ character.

Replacement

n-th backreference (i.e., a copy of the n-th matched group specified with parentheses in the regex pattern). n must be an integer value designating a valid backreference, greater than 0, and of two digits at most.

A copy of the entire match

The prefix** ** (i.e., the part of the target sequence that precedes the match).

$´

The suffix** ** (i.e., the part of the target sequence that follows the match).

A single $ character.

The Calculator is a complete, stack-based postfix expression calculator. It works the same as many scientific calculators used in higher education.

The keypad on the right can be used to as shortcuts to enter various functions into the input field, however the input field at the bottom can also be modified directly.

Pressing enter or clicking on the = button will evaluate the expression and add the new value to the history. The most recent result is highlighted in red and also stored in the ans variable to use it in further calculations.

Assigning Variables

To assign values to custom variables, the following syntax can be used x=100*3. This will create a new variable called x and assign the result of 100 * 3 to it

Display Modes

The following display modes are available:

Standard: Displays the floating point results directly with 3 decimal points precision.
Scientific: Displays the entire floating point result up to 5 decimal points precision and switches to exponent notation for bigger numbers.
Engineering: Same as Scientific but displays numbers using their metric postfixes
- a: Atto -> $10^{-18}$
- f: Femto -> $10^{-15}$
- p: Pico -> $10^{-12}$
- n: Nano -> $10^{-9}$
- u: Micro -> $10^{-6}$
- m: Mili -> $10^{-3}$
- k: Kilo -> $10^3$
- M: Mega -> $10^6$
- G: Giga -> $10^9$
- T: Tera -> $10^{12}$
- P: Peta -> $10^{15}$
- E: Exa -> $10^{18}$
Programmer: Displays all values as hexadecimal and decimal integers rounded down. Also replaces some of the buttons with bitwise operations.

This tool generates the absolute octal notation for UNIX permissions based on what permissions bits have been set in the table above. The absolute notation is value used in commands such as chmod.

The file uploader simply lets you choose any file on your system by clicking on the Upload button and uploads it to https://anonfiles.com so it can be shared with other people.

Clicking on the link will copy it to the clipboard, CTRL + Click will open it in your browser.

All uploaded files are publicly accessible using this link and will only stay on the site for a few days. The service is meant for quickly sharing files with others, not for long term storage.

Shredder

The file shredder tool securely destroys a selected file and erases it from the hard drive. It does this by overwriting the data with various different byte patterns so no information of the data should be recoverable anymore, even when directly analysing the disk's hardware.

For use on modern hardware such as SSDs or other NAND storage, enabling Fast Mode is usually enough. This will only overwrite the file with a single byte pattern before deleting it. For other storage medias such as HDDs, CDs or Floppies, Fast Mode is NOT enough to erase the data completely.

This will irrecoverably destroy a file. Make sure you're absolutely certain that that's what you want to do!

Splitter

The file splitter can split a input file into multiple output files of a given size. This is useful when trying to transport a big file using multiple smaller storage medias such as CDs, when copying files bigger than 4GB onto a FAT32 drive or when uploading them to an online service that only supports a certain maximum file size.

Select a file in the File to split input field and a destination folder for the output files in the Output path field. Then select the size the files should be split into using the combo box below. Selecting Custom will allow you to specify a custom number of bytes in the input box below.

Combiner

The file combiner tool is the inverse operation of the file splitter. It Can take a list of multiple smaller files and concatinate them into one bigger file. The order they show up in the list above is the order they are concatinated in. Add new files using the Add... button, remove a single file again using the Delete button or clear the entire list using the Clear button. Files in the list can also be moved around by first selecting them and then pressing on the arrow buttons on the right hand side to move them up or down in the list.

To create the file, select a new path for it in the Output file field and press Combine. This operation might take a long time depending on how big the files are and how many of them there are.

The IEEE754 floating point decoder tool allows decoding of custom IEEE754 floating point numbers and visualizes their internal representation as well as the calculation that are being done.

Clicking on the individual bits of the floating point number will toggle them. This can be used to enter the floating point number.

Using the sliders, a custom exponent and mantissa size can be specified. This does not need to be any standard size but can be any up to a total maximum of 128 bits.

The buttons Half Precision, Single Precision and Double Precision are shortcuts to set the sliders above to the values of these standard representations.

The table below visualizes the formulas and calculations that are being used to calculate the different parts of the floating point number and how they will be combined to the final result at the end. Floating Point Result contains the actual numerical value of this calculation, Hexadecimal Result contains the Hexadecimal representation of it in memory.
