Translation flow

Translation is split into a few phases usually separated by files. They go in the following order.

• import_resolver - download files by urls in import statements and embeds them into one big file
• ast_gen - figures best Solidity compiler version and downloads its executable
• solidity_to_ast4gen - converts Solidity AST format into our internal AST format
• ast_transform.pre_ti - applies transforms which are not relying on type information
• type_inference.stage1 - infers types based on direct contextual information
• type_inference.stage2 - infers types using bruteforcing by repetition
• ast_transform.post_ti - applies transforms reliant on type information
• translate_ligo - makes translation of AST nodes to textual code representation

Common abbreviations

jl - join list. A list of something to be joined later ds - default state. Translation stage which generates default contract state needed for its origination ti - type inference sink_list - an array holding data to be prepended or, sometimes, to be placed at the top
