Miria Code Editor

This is a little project that was made to practice the concepts of Vue and the concepts of grammars, especifically, the context free grammars for creating a new programming language called Miria.

Features

The main view consist of a text area and a div that mimics a console in which the ouput of the code will appear. Miria is still a very young language and thus only supports the following:

• Declaration and assignment of variables
• If statements
• For, while and do-while statements

These specs a thoroughly explained in miria documentation here. The classic hello world program in Miria would be as follows:

define main as fun() -> void {
  log("Hello world")
}

Miria also recognizes errors related to data types, using variables that are not defined and ilegal operations.

Known bugs

• Miria does not recognize scopes, thus when creating a variable inside any loop, miria will complain arguing that the variable already exist

Future improvements

• Add break like statements
• Fix the bug related to scopes
• Add the ability to create arrays
• Add the ability to create functions

Technologies used

• Nearley was used to generate the parser for miria. The miria.ne file, which contains miria's grammar, can be found in the src/grammar/parser directory
• Codemirror was used as the text editor

Huge thanks to @fireship-io for their tutorial on a css-only side navigation bar that ultimately defined the layout of the app.
