Summary

Major maintainability refactor that breaks the monolithic ASTools.py (and the nine standalone CmdLine*.py scripts) into a proper aspython package with a single unified CLI, while keeping every legacy entry point working.

What changed

New aspython package

ASTools.py was split into 21 focused modules:

Module Contents
aspython.project Project class
aspython.library Library class
aspython.package Package class
aspython.task Task class
aspython.deployment SwDeploymentTable
aspython.config CpuConfig
aspython.build buildASProject / batchBuildAsProject / ASProjetGetConfigs
aspython.simulation CreateARSimStructure
aspython.paths path helpers (getASPath, convertAsPathToWinPath, ...)
aspython.models dataclasses (BuildConfig, Dependency, LibExportInfo, ProjectExportInfo)
aspython.xml_base xmlAsFile base class
aspython.returncodes ASReturnCodes, PVIReturnCodeText
aspython.utils toDict
aspython.installer Inno Setup installer helpers
aspython.hmi Loupe UX HMI packaging
aspython.unittests UnitTestServer
aspython.upgrades installBRUpgrade
aspython.cnc CNC config helpers (lazy lxml import)
aspython.logging_setup shared logging + Windows ANSI console init

Unified aspython CLI

All nine CmdLine*.py scripts are now subcommands of a single aspython console script:

Legacy script New command
CmdLineBuild.py aspython build
CmdLineARSim.py aspython arsim
CmdLineExportLib.py aspython export-libs
CmdLineDeployLibraries.py aspython deploy-libs
CmdLineGetSafetyCrc.py aspython safety-crc
CmdLineGetVersion.py aspython version
CmdLineCreateInstaller.py aspython installer
CmdLinePackageHmi.py aspython package-hmi
CmdLineRunUnitTests.py aspython run-tests

Each subcommand lives in its own aspython/cli/<name>.py module exposing add_subparser / run, and aspython/cli/main.py wires them up with shared -l/--logLevel and -v/--version flags.

Backwards compatibility

Nothing existing breaks:

  • import ASTools still resolves and re-exports the full public API, with a DeprecationWarning.
  • ColorCodedLog, UnitTestTools, ASCncConfig, and top-level _version are also re-export shims.
  • Each CmdLine*.py script is now a tiny shim that delegates to aspython <sub> so existing CI / batch files keep working (and emit a DeprecationWarning pointing at the new command).
  • InstallUpgrades.py keeps its standalone CLI but imports installBRUpgrade from aspython.upgrades.

Packaging & tooling

  • pyproject.toml with setuptools backend, dynamic version from aspython._version, aspython console_scripts entry, and a [dev] extra (pytest, ruff, pyinstaller).
  • packaging/aspython.spec to build a single-file aspython.exe via PyInstaller.
  • .github/workflows/ci.yml runs pytest + ruff on Windows across Python 3.10 / 3.11 / 3.12 and attaches the built exe to tagged releases.

Tests

New tests/ suite (57 tests, all green):

  • test_smoke_imports.py — every submodule imports cleanly + the public API surface is preserved.
  • test_models.pyBuildConfig (incl. legacy typ= kwarg), Dependency, ProjectExportInfo partition / extend.
  • test_paths.py — pure path helpers.
  • test_cli_smoke.pypython -m aspython --help + --help for every subcommand + import ASTools regression check.

Version

Bumped to 0.3.0 with a CHANGELOG entry and a migration table at the top of the README.

Migration

Existing users:

pip install -e .[dev]
aspython --help

Old invocations (python CmdLineBuild.py ..., import ASTools) keep working but print a DeprecationWarning.

Test plan

  • python -m pytest tests -q → 57 passed
  • python -m aspython --help lists all 9 subcommands
  • python -m aspython <sub> --help works for every subcommand
  • import ASTools still exposes Project / Library / buildASProject / ASReturnCodes

Split the monolithic ASTools.py into a proper aspython package with focused submodules (project, library, package, task, deployment, config, build, simulation, paths, models, xml_base, returncodes, utils, installer, hmi, unittests, upgrades, cnc, logging_setup) and consolidate the nine CmdLine*.py scripts behind a single aspython CLI with subcommands.

Highlights:
- New aspython package + aspython CLI (build, arsim, export-libs, deploy-libs, safety-crc, version, installer, package-hmi, run-tests).
- Backwards compatible: import ASTools and python CmdLineXxx.py ... still work via deprecation shims.
- Added pyproject.toml (editable install + console_scripts + dev extras), PyInstaller spec, and GitHub Actions CI.
- Added pytest suite (57 tests) covering imports, models, path helpers, and CLI dispatch.
- Bumped version to 0.3.0; updated CHANGELOG and README migration table.

Resolves the conflict introduced by the AS6 fix on main (#16). The fix to ASTools.getASPath / Project._parseASVersion has been ported into the new package locations:

- aspython/paths.py: added _AS_BASE_CANDIDATES + _findASBase() so AS6 (which installs under 'C:\Program Files (x86)\BRAutomation') is discovered alongside the legacy 'C:\BrAutomation'.
- aspython/project.py: Project._parseASVersion now returns 'AS6' for AS 6.x (major-only folder) and keeps 'AS<major><minor>' for AS <= 4.x.
- tests/test_paths.py: covers _findASBase preference + legacy fallback.
- tests/test_project.py: covers AS4/AS6 version parsing.

The top-level ASTools.py shim is kept unchanged (kept ours).
- Remove 'aspython.installer_assets' from packages (directory was never created; the .iss/.bat assets live in top-level Files/ instead).
- Switch project.license from deprecated TOML table form to SPDX string 'MIT'.

Fixed in commit a59725cbuildASProject now returns subprocess.CompletedProcess(commandLine, process.returncode) instead of the raw Popen instance. The streaming/logging behavior is fully preserved (output is written line-by-line to the log file and via logging); callers only access .returncode so no captured stdout is needed on the returned object.

Bugs fixed (clearly correct, mostly pre-existing in legacy ASTools.py):

- library.py addObject: missing () on os.path.isdir guard; copy into self.dirPath instead of self.path (.lby file).
- library.py addDependency: replace 'is not Dependency' (always true) with isinstance check; append the XML element to the Dependencies container instead of the cached _dependencies list.
- project.py exportLibraries: actually pass the buildConfigs parameter to lib.export instead of always self.buildConfigs.
- project.py createArsim: splat *configNames and forward destination so the legacy alias is callable.
- paths.py getAsPathType: guard against empty string so it returns None instead of IndexError.
- cli/export_libs.py: --configuration is now required; --whitelist/--blacklist default to [] (was '').
- cli/installer.py: --output and --appName are now required so the iscc command line never contains literal 'None'.
- pyproject.toml: lxml moved out of required dependencies into a 'cnc' extra (matches the optional import guard in aspython.cnc); kept under [dev] so tests still cover it.

Pushed 8200e74 addressing the Copilot review. Summary by category:

Fixed in this push (clearly correct, mostly pre-existing legacy bugs)

# File / Issue Fix
5 library.py addObject — missing () on os.path.isdir and copy into .lby file path Guard now calls os.path.isdir(path); copy target is self.dirPath.
10 library.py addDependencyis not Dependency is always true; appended to wrong list Switched to isinstance(...) and append the new element to the <Dependencies> XML container (creating it if missing).
11 project.py exportLibraries ignored its buildConfigs parameter Now forwarded to lib.export(...).
15 project.py createArsim passed a tuple as one config and missing required destination Splats *configNames and forwards destination (defaulting to self.path).
12 paths.py getAsPathType IndexError on empty string Added falsy guard returning None.
9 + 13 cli/export_libs.py--configuration optional but iterated; --whitelist/--blacklist defaulted to '' (str vs list) --configuration is now required=True; whitelist/blacklist default to [].
16 cli/installer.py — optional args could produce /ONone, /dAppName=None --output and --appName are now required=True (only the truly mandatory ones — simDir/userDir/hmiDir already gate their flags conditionally in compileInstaller).
14 pyproject.tomllxml listed as required despite optional-import guard Moved lxml to a new [cnc] optional extra; kept under [dev] so tests still exercise it.
17 pyproject.toml — bogus aspython.installer_assets package Already removed in 932b1a0.

All 62 tests still pass.

Flagged for your review (intentional or pre-existing behavior — did not change)

These are real points but the changes are either behavior-preserving risks I don't want to slip into this refactor PR, or design decisions worth a separate ticket. Tagging @scott for sign-off:

  • Fix User and HMI files in ARSim cmd line interface  #1 project.py:77 bitwise & between booleans. Pre-existing in ASTools.py; both operands are .lower() == 'something' which always yield real bool, so this works but is non-idiomatic. Suggested follow-up: change to and in a separate cosmetic PR.
  • Support referenced libraries #2 hmi.py:43 subprocess.run(list, shell=True). Pre-existing; this calls electron-packager via npx, where the existing quoting happens to work on the dev machines. Switching to shell=False could regress current users. Worth a dedicated test/run before changing.
  • Change webHMI name to Loupe UX #3 build.py:110 buildASProject annotated CompletedProcess but returns Popen. Pre-existing. Several callers (cli/build.py, cli/export_libs.py) currently access .returncode after the call, which only works because they wait via .communicate() upstream — keeping the existing surface preserves all legacy callers. Recommend: convert to subprocess.run in a separate PR with caller audit.
  • Fix PVIReturnCodeText uncaught error if unknown error code #4 cli/run_tests.py:33 unused --all flag. Pre-existing in CmdLineRunUnitTests.py; removing it would be a CLI-breaking change for anyone passing -a. I'd rather leave it as a noop placeholder until we decide on filter semantics.
  • InstallUpgrades.py does not support relative paths #6 upgrades.py:18 subprocess.run(' '.join(cmd)). Pre-existing in InstallUpgrades.py; the joined string approach has always been used for the /silent AS upgrade installers and works through cmd parsing on the runner machines. Changing to a list might regress argument splitting. Needs manual test with a real upgrade .exe before changing.
  • feat[CmdLineExportLib]: Optimize argument-handling / Allow libraries to be referenced in projects #7 installer.py:56 subprocess.run(list, shell=True) for ISCC. Same class of issue as Support referenced libraries #2; pre-existing. ISCC currently launches correctly because the args don't contain spaces. Wants a test on a path with spaces before flipping shell.
  • Fix logical path to actual path functions  #8 build.py:63 embedded quotes around os.path.abspath(project). Pre-existing. Removing the quotes might break invocations against project paths with spaces (which is why they were added). Should be tested with a "Program Files"-style project path before removing.

Happy to address any of the flagged items in a follow-up PR — let me know which ones you want done now vs. deferred.
