Module artifacts 

Finding and loading one contract’s debug artifacts from a directory.

An output directory holds the global resource file (ethdebug.json from older compilers, ethdebug_resources.json from modern ones), one program artifact per contract and environment (<Contract>_ethdebug.json for creation code, <Contract>_ethdebug-runtime.json for runtime code), and, for compilers that predate ETHDebug, a combined.json with legacy source maps. load_debug_program is the one path through all of that: ETHDebug first, the legacy map as a fallback, and the source text read from the compilation record or from disk. The CLI and the DAP server both load through it, so a directory that works in one works in the other.

Structs

DebugProgram

One contract’s debug information as loaded from its artifacts.

Enums

CodeGenerator

Which of solc’s code generators produced a program.

Functions

contract_name_from_program_path

The contract name a program artifact’s file name carries.

ethdebug_resources_from_metadata

The resources record of an ETHDebug metadata file: its resources entry when it has one, otherwise one assembled from the compilation, types, and pointers it carries.

find_ethdebug_metadata

The global ETHDebug resource file in root, under either of its names.

find_program_ethdebug

The ETHDebug program artifact for one contract and environment.

load_debug_program

Loads a contract’s debug program from root: the ETHDebug artifacts when present, otherwise the legacy source map in combined.json.

load_debug_program_with_sources

The same, also looking for sources in source_roots.

load_storage_layout

The <Contract>_storage.json that solc --storage-layout -o <root> writes, when it is there. A missing file is not an error: the layout is optional debug information. An unreadable one is, because the user compiled with it and would otherwise get a silent “no storage layout” that looks identical to never having asked for it.

read_debug_source

Reads a source file named by the compiler, trying it relative to the artifact directory, to that directory’s parent, and as given.

read_debug_source_from

The same, looking in extra_roots first: directories the user named because the sources are not where the artifact’s paths reach.

read_json_file

Parses a JSON file, naming the file in the error.

source_candidates

Where a source path recorded in an artifact might be on disk.
