New Nexss Programmer 3.0+ in C

From the version of 3.0, main engine of the Nexss Programmer will be written in C.


Nexss Programmer now supports Android platforms (Experimental).


Nexss Programmer now supports Wasm files.

NOTE: WIP: compile and execute each supported programming language as Wasm+Wasi and many more wasm related features..

Node.js and TypeScript - new runtime - Deno

Deno is "A modern runtime for JavaScript and TypeScript.".

# Node.js
nexss js default compiler deno # set your default runtime to deno
nexss js default compiler unset # to reset to default

# TypeScript
nexss ts default compiler deno # set your default runtime to deno
nexss ts default compiler unset # to reset to default

or set compiler per file individually. Works for every implemented language.

// nexss-compiler: deno

console.log(`Hello from Deno! ${Deno.version.deno}`)

and run with nexss myfile.js or nexss myfile.ts

New language - Solidity

Nexss Programmer 2.5.101 Supports Solidity - Solidity is an object-oriented, high-level language for implementing smart contracts.

More info about languages

New readme functionality. You can now read more info from the README.md file from selected language eg.

🔥 Nexss Programmer is not only a cli tool 🔧 which helps to:

✅ Easy and intuitively install programming environments


  • nexss r install OR nexss py install OR nexss php install OR ..

  • nexss [language file extension] install

  • NEW: easy shortcuts: nexss py d (creates file with default template), nexss py h (with helloWorld template), nexss py e (and empty file - if exists in the templates - !empty.[extension]) (2.4.8+)

Compile, compose over 50 programming languages

if there is no compiler installed, nexss programmer will install it automatically.

  • nexss program.r
  • nexss program.[any extension]
  • npx @nexssp/cli program.r # without installing nexss
  • nexss file add my.rs --edit # Will open list of templates to select from for particular language, install editor (if not exists) and open file for editing.

Run any programming language in seconds (eg. Google Colab Notebook)

!npm i -g @nexssp/cli
!nexss f a my.r --helloWorld # Add template
!nexss my.r # run program
# {"HelloFromR":"4.0.5","nexss":"2.2.35"}
!nexss Id # run Id package
# {"nxsOut":"cknvpfni00000blqefsh37hwa","nexss":"2.2.35"}
!nexss f a my.cpp --helloWorld # Add template
!nexss my.cpp
# {"outputCPP":"Hello from C++ 17!","nexss":"2.2.35"}

And much, much more

🔄NOTE: Upgrade to the latest versions

  • npm upgrade -g @nexssp/cli # upgrade nexss programmer
  • nexss l u # the same as nexss langauge update // Updating all installed language definitions
  • nexss pkg u # the same as nexss package update // Updating all installed Nexss Programmer Packages
  • nexss cache rebuild # rebuilding cache // handy when developing new language configurations (now is over 50)

  • --nxsI - interactive mode. When you need input from the user, use this flag.

Example commands

Note: nxsOut is a default output/variable/field from a package, or function if use with Nexss Programmer project. You can change it by --nxsOut


npm i @nexssp/cli -g # install nexss programmer globally. Run everywere
npm init && npm i @nexssp/cli@2.4.20 # install per project

Helper Functions

nexss -help # displays all available helper functions
nexss -env # displays environment info: versions, paths, package managers etc. (nexssp-os env)

Create new files from templates

# Below we use package Id which generates unique Id (shorcuts)
nexss py h # it will create new helloWorld template for python
nexss js d # new default template for NodeJS
nexss v e # new empty template for Vlang

nexss file add my.r # it will show new templ
nexss file add my.r help # displays help for function
nexss Id help # displays help for package (Id is a Nexss Programmer's package)

Compile programs / Installing programming environments

npx nexss program.r # without installing, just compile and run program
nexss helloWorld.py # it will compile program (if compiler does not exist, it will be installed)
nexss php run "print('x');" # 2.2.37+
nexss file add my.rs --edit # Will open list of templates for particular language, install editor (if not exists) and open file for editing.


Global packages

Nexss Programmer has custom packages, written to show the possibilities of it. For example below there is a global package Id. To run it nexss Id. To see help nexss Id help. Every package in the nexss programmer is just a Nexss Programmer Project. You can add your own packages to global folder. Use nexss -env to see packages folder.

nexss Id # Generates Id in the nxsOut
nexss Id --nxsAs="X" # if nxsAs it will be saved as
nexss Id --nxsAs="X" --server # it will start a server
nexss Id --nxsField # nxsField can be used for select data from some field.
# Above nxsField is the same as nxsField=nxsOut
nexss https://nexss.com --nxsField --server # As nexss [url] reads url, with --server it will serve the url on

Custom Packages

You can also run commands/packages/projects as absolute urls eg.

nexss /my/absolute/url --param=1

Nexss Programmer - How it works?

Stage 1

At first Nexss Programmer checks if the first argument passed is folder or file (program. eg myprogram.py).


If it is a folder it will check if there is a _nexss.yml file inside, which is basically a config for Nexss Programmer package. If it is there then it will run this package. As you will find out more Nexss Programmer package can contain many programming languages solutions.


If it is a file (other then .nexss) it will go and generate file definition (1 in this case). You can see what is beeing generated by adding --nxsDryFiles

nexss my.nexss --nxsDryFiles # Will show files collected (which will be run) in order with all the parameters
  "name": "^^dir",
  "input": [
      "name": "file",
      "validate": [
          "type": "required"
  "specialArgs": [],
  "lineNumber": 9,
  "path": "/root/.nexss/packages/@dev/!Exec",
  "filename": "/root/.nexss/packages/@dev/!Exec/my.nexss"
nexss.my.nexss --nxsDry # will show the streams which are generated, with compilers, builders

WIP - Add more here later..


Nexss Programmer apart from being innovative technology, uses great libraries and technologies. Please consider also support them.

For some of the languages compiler installations for Windows we use great Scoop from Luke Sampson. Please also consider support him.

Note for Windows 10 and 11 Python users

On Windows OS there are default files python.exe and python3.exe and they pointing to the shop which causing that is hard to install Python from other sources and issue appeared for many users. If you wish to use different Python distributions eg. provided by the Nexss Programmer please run below command. NOTE: you may want to make a backup to your files before deleting them entirely.

# It will delete python.exe and python3.exe which point to the shop.
Remove-Item $env:USERPROFILE\AppData\Local\Microsoft\WindowsApps\python*.exe

You may need to install Python manually if any other issues appear and then use Nexss Programmer. It will recognize any installed python and you should be able to use the Nexss Programmer without any issues.
