- Download a source tarball.
- Build and install it, as described in INSTALL.
These steps take 30 to 60 seconds on most machines. After that, you can

oil-native is a preview release, not a working shell.
Oil has three major sources of docs:
- Lines of source, counted in different ways:
- osh-cloc. OSH and common
libraries, as measured by the cloc tool.
- src. The whole Oil repo organized by
type of source file.
- oil-cpp. The C++ code in the

- Lines of dependencies:
- pydeps. Oil code plus the Python
- nativedeps. Oil code plus A
slice of CPython.
- Bytecode Metrics
- OVM / CPython

Main Test Suites

These files may help you understand how Oil is implemented, i.e. with
domain-specific languages and code generation.
- _devbuild/gen/id.h. A list of language
elements, used in the lexer and in multiple parsers and evaluators.
- The regex-based lexer uses two stages of code generation:
- frontend/syntax.asdl. The syntax tree
for OSH and Oil.
- oil_lang/grammar.pgen2. The
expression grammar for Oil. In contrast, the OSH parsers are hand-written.
