Investigation: Import/Export Error

Time: 2025-12-07 20:09 EST Status: ✅ RESOLVED - No errors found

Steps Taken:

  1. ✅ Reviewed existing code in json_export.py
  2. ✅ Checked import statements in AlexCAD.py
  3. ✅ Verified test results (all passing)
  4. ✅ Attempted to run AlexCAD (appears to launch successfully)
  5. ✅ Tested Python json module import (works correctly - version 2.0.9)
  6. ✅ Tested json_export module import in conda environment
  7. ✅ Ran test suite (all tests pass)

Findings:

  • ✅ import json is present in json_export.py (line 11) - WORKING
  • ✅ from packages import json_export is used in AlexCAD.py (lines 1087, 1119, 1233) - WORKING
  • ✅ Additional import json in AlexCAD.py (line 1235) for validation function - WORKING
  • ✅ All imports syntactically correct and functional
  • ✅ Python json module (standard library) version 2.0.9 available
  • ✅ All 57 tests passing
  • ⚠️ Note: Must run within alex_test conda environment (requires numpy)

Resolution:

No actual errors found. All JSON import/export functionality is working correctly. The code is stable and ready to use.

To use the JSON export/import features:

  1. Launch AlexCAD: conda activate alex_test && python scripts/AlexCAD.py
  2. Use File menu:
    • "Export Library to JSON..." - Export current parts library
    • "Import Library from JSON..." - Import parts from JSON file
    • "Validate JSON Library..." - Validate a JSON library file

Possible User Issue:

If user encountered an error, it may have been:

  • Running outside conda environment (missing numpy dependency)
  • Temporary issue that has been resolved
  • Different error not related to JSON import/export

Enhancement: Searchable Library Selector for Export

Time: 2025-12-07 20:18 EST Status: ✅ COMPLETED (Enhanced 20:21, Redesigned 20:24)

User Requests:

  1. "The export parts library to json, should have a library selector: which library do you want to export?"
  2. "Need a scroll window... who know how many libraries we will have."
  3. "I'm linking a scrollable list (no radio boxes) with a empty text entry at the top. start typing and all non-matching libraries disappear. use standard wild card chars."

Implementation:

Modified alex_export_library_json() function to:

  1. ✅ Display dialog showing all available libraries
  2. ✅ Show part count for each library
  3. ✅ Allow user to select which library to export
  4. ✅ Update file dialog title and default filename based on selection
  5. ✅ Export the selected library (not just Main)
  6. ✅ Scrollable listbox to handle unlimited libraries
  7. ✅ Real-time search filter with wildcard support
  8. ✅ Alphabetical sorting (Main always first)
  9. ✅ Double-click to select
  10. ✅ Enter key to confirm

Changes Made:

  • File: scripts/AlexCAD.py
  • Function: alex_export_library_json() (starting line 1085)
  • Added:
    • Library discovery (scans part_libraries_dir for all libraries)
    • Filter text entry at top of dialog
    • Scrollable Listbox (replaced radio buttons)
    • Wildcard filtering using fnmatch module (supports * and ?)
    • Real-time filter - list updates as you type
    • Dynamic part count display
    • Library-specific default filename (e.g., "main_library.json", "user_library.json")
    • Alphabetical sorting with Main library always first
    • Double-click selection
    • Enter key binding

UI Features:

  • Window size: 450x500 (taller for filter + list)
  • Filter entry: Text box at top with label "Filter (use * and ?):"
  • Listbox: Scrollable list showing "LibraryName (X parts)"
  • Wildcard support:
    • * matches any characters (e.g., test* matches "test", "test1", "testing")
    • ? matches single character (e.g., test? matches "test1", "testA")
    • Case-insensitive matching
  • Auto-selection: First matching item auto-selected as you filter
  • Focus: Filter entry has focus on open (start typing immediately)

Filter Examples:

  • main → Shows only "Main"
  • *test* → Shows all libraries containing "test"
  • user* → Shows "User" and any libraries starting with "user"
  • ??? → Shows all 3-character library names
  • (empty) → Shows all libraries

Keyboard Shortcuts:

  • Type → Filter list in real-time
  • ↑/↓ → Navigate list
  • Enter → Select and export
  • Double-click → Select and export
  • Esc → Cancel (standard Tkinter behavior)

Available Libraries Detected:

  • Main (15 parts)
  • User
  • test

Testing:

  • ⏳ Needs manual testing in GUI
  • ⏳ Should verify filtering works with wildcards
  • ⏳ Should verify all libraries can be exported successfully
  • ⏳ Test with many libraries to verify scrolling

Bug Fix: Listbox Metadata Error

Time: 2025-12-07 20:31 EST Status: ✅ FIXED

Issue:

When opening the export dialog, got error:

_tkinter.TclError: unknown option "-name"

Root Cause:

Line 1167 attempted to use listbox.itemconfig(tk.END, {'name': lib_name}) to store metadata. Tkinter's Listbox widget doesn't support custom metadata/options.

Solution:

  • Removed the invalid itemconfig() call
  • Library name is already extracted from display text in get_selected_library_name() function
  • Display format: "LibraryName (X parts)" → Extract everything before (

Verification:

  • Debug output confirmed all 3 libraries found: ['Main', 'test', 'User']
  • Library discovery working correctly
  • Fix removes the TclError

Enhancement: Auto-Wildcard Filter

Time: 2025-12-07 20:34 EST Status: ✅ COMPLETED

User Feedback:

"working... but we need to include a '*' after any letters already typed. when I type 't' they all disappear until I complete 'test' then test reapears."

Issue:

Filter was too literal - typing "t" only matched libraries named exactly "t", not libraries containing "t".

Solution:

Modified on_filter_change() to automatically wrap search terms with wildcards:

  • User types: t → Pattern becomes: *t* (contains "t")
  • User types: test → Pattern becomes: *test* (contains "test")
  • User types: *test → Pattern stays: *test (user's explicit wildcard)
  • User types: test? → Pattern stays: test? (user's explicit wildcard)

Behavior:

  • Auto-wildcard: If no * or ? in pattern, wrap with *pattern*
  • Manual control: If user includes wildcards, use pattern as-is
  • Empty filter: Shows all libraries (pattern = *)

Examples:

User Types Pattern Used Matches
t *t* test, Test, MyTest, etc.
main *main* Main, MainLib, etc.
test* test* test, test1, testing (user's explicit pattern)
* * All libraries
(empty) * All libraries

UI Update:

  • Changed label from "Filter (use * and ?):" to "Filter:"
  • Simpler, cleaner - wildcards are automatic
