ERA COMPILER

This is system-level programming language compiler for processors with ERA architecture.

Basic architecture

The most abstract architecture of the compiler:

File with code -> Lexical Analyzer ->
-> Tokens -> Syntax Analyzer ->
-> Abstract Syntax Tree -> Semantic Analyzer ->
-> Annotated AST -> Generator ->
-> File with compiled code

Compiler usage

Compiler works as console appilcation.
The main command is ERACompiler.
There are several arguments available:

• -h : see help
• -s {filename} : specify source files to be compiled
• -o {filename} : specify output files
• -d {paths} : specify folders with the code to be compiled (cannot be used with -o parameter)
• -p : force to create folders if they do not exist
• --err : display more detailed error messages
• --lex : perform tokenization only
• --syn : perform tokenization and AST assembling
• --sem : perform tokenization, AST assembling, and AAST assembling
• --semext : same as --sem with more detailed output
• --asm : full compilation with the assembly code output
• --prefix : custom filename prefix for output files
• --ignconf : ignore configuration file and rely only upon command-line flags

Examples of commands:
ERACompiler -h - get help message
ERACompiler -s test.txt folder1/file1.java - will compile source files to compiled_test.txt and folder1/compiled_file1.java
ERACompiler --lex -o out.a - will compile default code.era file to the out.a using only tokenization

ERA Simulator

Here is the link to the ERA Simulator GitHub repo:
https://github.com/egorklementev/era_simulator

It is aslo a Windows x64 command-line application with similar arguments and way of usage.

Vim syntax highlight

Since no one want to program in the "notepad.exe" (why not?), there is a special era.vim file that adds a support of ERA language syntax highlighting. You may find it in the ../DOCS folder. How to use Vim and its syntax highlighting, you may find in Google.

The support for VS/VSCode, Intellij IDEA, and etc. will be added later.

ATTENTION:

It is highly recommended to read example.era file which gives basic understanding of the ERA language.
example.era

Also, read documentation files in ../DOCS folder for more information about ERA language.
