Oil Version 0.6.pre2

What's New

• The Release announcement has a high-level summary of changes.
• Details are in the raw git change log. Some of these changes may not affect the release tarball (e.g. tool changes).

Docs For End Users

• INSTALL. How to install OSH. This text file is also at the root of the tarball.
• OSH Quick Reference, with Examples (in progress). This document underlies the OSH help builtin. It also gives a rough overview of what features OSH implements.

Docs For Developers

• Github Wiki for oilshell/oil

Metrics

• Count lines of source code in different ways:
  • oil-osh-cloc. The core of Oil, as measured by the cloc tool.
  • src. The whole Oil repo organized by type of source file.
  • parser. How big is the parser?
  • runtime. How big is the runtime?
• Count lines of dependencies:
  • pydeps. Oil code plus the Python standard library.
  • nativedeps. Oil code plus A slice of CPython.
• Bytecode Size

Oil Tests

• Spec Tests. Test OSH behavior against that of existing shells.
• Wild Tests. Parsing and translating thousands of shell scripts with OSH.
• Unit Tests. Python unit test results.
• Gold Tests. Comparisons against bash (using implicit assertions, no golden output.)
• osh2oil Tests. Test the conversion of OSH to Oil.

OPy Tests

The OPy compiler is used to compile Oil to bytecode, but isn't itself part of the release.

• build-oil-repo
• test-gold
• test-oil-unit-byterun
• regtest-compile
• regtest-verify-golden

Tree-shaking:

• Symbols in Oil
• Symbols in OPy

Manual Tests

• [ ] Test build and install on OS X

Benchmarks

• OSH Parser Performance. How fast does OSH parse compared to other shells?
• OSH Runtime. How fast does OSH run compared to other shells?
• Virtual Memory Baseline. How much memory to shells use at startup?
• OVM Build. How long does it take for end users to build Oil? How big is the resulting binary?

NOTE: OHeap was broken in this release due to the removal of bytearray. It may be back in the future.
