alpha-language-support

Alpha Language Support was created to help write scripts using the alpha language.
Alpha scripts must have the .al extention

Features

Alpha Language Support currently supports:
    -syntax highlighting
    -syntax analysis
    -compile and run

Syntax Analysis

The syntax analyser is activated upon file save and
the file is parsed. Error messages can be examined
in the Output Alpha panel (see View Parse Output on how to open the Output panel).
The messages are not very accurate but they provide a line number to help with debugging.

The parser can also be activated using the Parse Grammar command.
To use the command, 
1) open the command palette with Ctrl+Shift+P
2) search Alpha Parse Grammar

The parsing results will be displayed in the Output panel

Compile and Run VM

To compile and run an alpha script, 
1) open the command palette with Ctrl+Shift+P
2) search Alpha Compile and Run VM

This will compile the active alpha file
and produce a .abc file with the same name
as the active file. 
Error messages from the compiler will be displayed
in the Output panel (see View Parse Output on how to open the Output panel).

The vm runs on a terminal (tested on powershell) and the output is displayed there.

You can also run an alpha script using F5, to do that
1) open .vscode folder (create one if it doen't exist)
2) create a launch.json
3) in the inputs field add the command: extension.compileAndRunVM
4) in the configurations add a launch request

Your launch.json should look like this.

You can suppress runtime warnings by adding a -Wno argument.

View Parse Output

To view the output of the parser
go to View -> Output (or Ctrl+Shift+U) and select the Alpha panel
