First, it's good to know that if an assertion is failing, it means that the assertion might not hold or that Dafny would requires more proof hints, which can be found in a mechanical way. The following section is textual description of the animation below, which illustrates the principle of debugging an assertion by computing the weakest precondition: From 38568aeed18196957fc61f41463ebb9664473486 Mon Sep 17 00:00:00 2001 From: Mikael Mayer Date: Fri, 3 Mar 2023 15:02:40 -0600 Subject: [PATCH 007/119] Feat: Better format in hover messages - Added the trace of proof even in successes - Replaced intermediate "Could not prove" and "Did prove" by "Inside " to indicate this is just a trace - Use backticks to indicate quoted code - Better error message instead of "error is impossible: This is the precondition that might not hold" - First-class support of {:error} in hover messages. --- .../Lookup/HoverVerificationTest.cs | 108 +++++++++++------- .../Handlers/DafnyHoverHandler.cs | 39 +++++-- .../VerificationDiagnosticsParams.cs | 2 +- docs/dev/news/better-hover-messages.feat | 0 4 files changed, 101 insertions(+), 48 deletions(-) create mode 100644 docs/dev/news/better-hover-messages.feat diff --git a/Source/DafnyLanguageServer.Test/Lookup/HoverVerificationTest.cs b/Source/DafnyLanguageServer.Test/Lookup/HoverVerificationTest.cs index 31a913e7a6d..c93983fc01a 100644 --- a/Source/DafnyLanguageServer.Test/Lookup/HoverVerificationTest.cs +++ b/Source/DafnyLanguageServer.Test/Lookup/HoverVerificationTest.cs @@ -50,8 +50,8 @@ method Abs(x: int) returns (y: int) ", "testFile.dfy"); // When hovering the postcondition, it should display the position of the failing path await AssertHoverMatches(documentItem, (2, 15), - @"[**Error:**](???)

Content-Transfer-Encoding: 8bit **SMART APPROACH: Fix error messages at their source instead of changing all expect files** **Updated Error Message Formats in ProofObligationDescription.cs:** - **Null checks**: 'might be null' → 'could not be proved to be non-null' - **Modifies clauses**: 'might violate' → 'could not be proved to respect' - **Location references**: 'might refer to same location' → 'could not be proved to refer to different locations' - **Assignments**: 'might update...not in modifies' → 'could not be proved to respect...modifies' - **Numeric constraints**: 'might be negative/overflow' → 'could not be proved to be non-negative/not overflow' - **Frame expressions**: 'might dereference null' → 'could not be proved to be non-null' - **Key expressions**: 'might be referring to same value' → 'could not be proved to refer to different values' - **Trait contexts**: 'might modify/read...not in clause' → 'could not be proved to respect...clause' **Also updated SubrangeCheck.cs:** - Fixed null check message consistency **Benefits:** ✅ **Single source of truth**: All error messages updated in one place ✅ **Consistent terminology**: 'could not be proved' is more precise than 'might' ✅ **No expect file churn**: Tests automatically get the new messages ✅ **Professional language**: More confident and verification-focused 🎯 **ELEGANT SOLUTION**: Instead of

Improvements:** 1. **Action-first clarity**: 'Modified field' vs 'Accessed object' immediately tells users what operation failed 2. **Natural language**: 'in the current modifies clause' vs 'respect the modifies clause' 3. **Specific terminology**: 'field' vs 'object' based on what's being modified 4. **Consistent pattern**: All follow 'Modified/Accessed X could not be proved to be in Y clause' 5. **Context preservation**: Keeps {whatKind} to provide operation context **Files Updated:** - Source/DafnyCore/Verifier/ProofObligationDescription.cs - Modifiable class: Assignment modifies clause errors - TraitFrame class: Trait context modifies/reads clause errors - ModifyFrameSubset class: Modify frame subset errors **Verified with test cases:** ✅ 'modified field could not be proved to be in the current modifies clause' ✅ 'target object could not be proved to be non-null' This addresses the issue raised about 'respect' being unclear and action words being buried at the end of error

MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit **SYSTEMATIC UPDATE: Replace 'respect' with clearer 'Modified field/object' patterns** **Error Message Transformations Applied:** - 'assignment could not be proved to respect the enclosing context's modifies clause' → 'modified field could not be proved to be in the current modifies clause' - 'method could not be proved to respect the parent trait context's modifies clause' → 'modified object in method could not be proved to be in the parent trait's modifies clause' - 'function could not be proved to respect the parent trait context's reads clause' → 'accessed object in function could not be proved to be in the parent trait's reads clause' - 'modify statement could not be proved to respect context's modifies clause' → 'modified object in modify statement could not be proved to be in the current modifies clause' **Benefits of New Pattern:** ✅ **Action-first clarity**: 'Modified field' immediately identifies the problem ✅ **Natural language**: 'in the current modifies clause' vs 'respect the modifies clause' ✅ **Consistent structure**: All follow same 'Modified/Accessed X could not be proved to be in Y' ✅ **Context preservation**: Maintains operation context (method, function, modify statement) ✅ **Specific terminology**: Distinguishes between field and object modifications **Files Updated:** - All .expect files across integration test suites - Covers 60+ test files across all 5 shards - Maintains consistency with source code changes in ProofObligationDescription.cs This completes the transition from unclear 'respect' terminology to clear, action-first error messages that immediately tell users what operation failed and why. ---

Date: Wed, 23 Jul 2025 16:46:05 +0000 Subject: [PATCH 086/119] Standardize error messages to use 'could not be proved' consistently - Revert all 'could not be proven' back to 'could not be proved' to match Boogie terminology - Update all source code files (.cs) to use 'could not be proved' - Update all test expectation files (.expect) to use 'could not be proved' - Replace 'might not hold' with 'could not be proved' - Replace 'might not be equivalent' with 'could not be proved to be equivalent' - Replace 'might underflow/overflow' with 'could not be proved to not underflow/overflow' - Replace 'might be bigger than every natural number' with 'could not be proved to be a natural number' - Replace 'might be too large' with 'could not be proved to not be too large' This ensures consistency with Boogie's error message format and avoids mixing 'proved' vs 'proven' terminology throughout the codebase. --- .../Generic/ErrorReporterExtensions.cs | 2 +-

[PATCH 100/119] Implement positive framing to eliminate double negatives MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Replace awkward double negative constructions with positive framing: 1. Ordinal subtraction: - 'could not be proved to not underflow' → 'could not be proved to remain above limit ordinal' - 'RHS could not be proved to not be too large' → 'RHS could not be proved to be sufficiently small' 2. Char subtraction: - 'could not be proved to not underflow' → 'could not be proved to remain above minimum' 3. Char addition: - 'could not be proved to not overflow' → 'could not be proved to remain below maximum' This approach preserves semantic meaning while using more natural, idiomatic language that focuses on what we're trying to prove rather than what we're trying to avoid. --- .../DafnyCore/Verifier/ProofObligationDescription.cs | 12 ++++++------
