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

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

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.

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.
