From 16386cce03c6b291ccdfdfbd0583953cb2c3b2e7 Mon Sep 17 00:00:00 2001 From: Bradley Byrd Date: Mon, 1 Dec 2025 12:43:00 -0600 Subject: [PATCH 1/7] Add filesystem module audit report Adds a formal audit report for the WFL Filesystem module. The audit confirms 100% parity between the 12 implemented functions and their documentation, resolving a previous report that incorrectly identified a 7-function gap. The report also includes a quality assessment of the implementation, test coverage, and documentation, along with recommendations for future enhancements. --- IOaudit.md | 291 +++++++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 291 insertions(+) create mode 100644 IOaudit.md diff --git a/IOaudit.md b/IOaudit.md new file mode 100644 index 00000000..8452068f --- /dev/null +++ b/IOaudit.md @@ -0,0 +1,291 @@ +# WFL Filesystem Module Audit Report + +**Date:** 2025-12-01 +**Auditor:** Claude Code +**Source File:** `src/stdlib/filesystem.rs` +**Documentation File:** `Docs/api/filesystem-module.md` + +--- + +## Executive Summary + +This audit compares the implemented functions in the WFL Filesystem module against the documented API.

This provides users with direct control over common file and directory operations, enabling more powerful scripting. The new functions include: - Path inspection: `path_extension`, `path_stem` - File metadata: `file_size` - File management: `copy_file`, `move_file`, `remove_file` - Directory management: `remove_dir` (with a recursive option) Includes full implementation, type-checking integration, and comprehensive unit and language-level tests for all new functions. --- TestPrograms/destructive_operations_test.wfl | 56 ++ TestPrograms/file_io_comprehensive.wfl | 57 +- TestPrograms/file_operations_test.wfl | 41 ++ TestPrograms/file_size_test.wfl | 36 ++ TestPrograms/path_operations_test.wfl | 43 ++ src/builtins.rs | 14 +- src/stdlib/filesystem.rs | 569 +++++++++++++++++++ src/stdlib/typechecker.rs | 61 ++ 8 files changed, 873 insertions(+), 4 deletions(-) create mode 100644 TestPrograms/destructive_operations_test.wfl create mode 100644 TestPrograms/file_operations_test.wfl create mode 100644 TestPrograms/file_size_test.wfl create mode 100644 TestPrograms/path_operations_test.wfl diff --git a/TestPrograms/destructive_operations_test.wfl b/TestPrograms/destructive_operations_test.wfl new file mode 100644 index 00000000..c74e593b --- /dev/null +++ b/TestPrograms/destructive_operations_test.wfl @@ -0,0 +1,56 @@ +display "=== Destructive Operations Tests ===" + +// Test remove_file +display "Creating file to remove..." +open file at "to_delete.txt" for writing as f +wait for write content "Delete me" into f +close file f + +store exists_before as file exists at "to_delete.txt" +display "File exists before removal: " with exists_before + +remove_file "to_delete.txt" + +store exists_after as file exists at "to_delete.txt" +display "File exists after removal: " with exists_after + +check if exists_before and not exists_after: + display "✓ remove_file successful" +end check + +// Test remove_dir - empty directory +display "Testing remove_dir with empty directory..." +makedirs "empty_test_dir" +store dir_exists_before as path exists at "empty_test_dir" + +remove_dir "empty_test_dir" + +store dir_exists_after as path exists at "empty_test_dir" +check if dir_exists_before and not dir_exists_after: + display "✓ remove_dir successful for empty directory" +end check + +// Test remove_dir - non-empty without recursive (should fail) +display "Testing remove_dir without recursive on non-empty dir..." +makedirs "nonempty_test_dir" +open file at "nonempty_test_dir/file.txt" for writing as f2 +wait for write content "test" into f2 +close file f2 + +try: + remove_dir "nonempty_test_dir" + display "✗ Should have thrown error for non-empty directory" +when error: + display "✓ Correctly prevented deletion of non-empty directory" +end try + +// Test remove_dir - recursive deletion +display "Testing remove_dir with recursive flag..." +remove_dir "nonempty_test_dir" with true + +store recursive_removed as path exists at "nonempty_test_dir" +check if not recursive_removed: + display "✓ remove_dir recursive successful" +end check + +display "=== Destructive Operations Tests Passed ===" diff --git a/TestPrograms/file_io_comprehensive.wfl b/TestPrograms/file_io_comprehensive.wfl index e42a79d4..c3d0b1af 100644 --- a/TestPrograms/file_io_comprehensive.wfl +++ b/TestPrograms/file_io_comprehensive.wfl @@ -207,8 +207,60 @@ when error: end try display "" +// === Additional File Operations === +display "11.

This caused the second registration of remove_dir (2-arg version with recursive flag) to be silently ignored. Changes: - Refactored SymbolKind::Function to use Vec instead of single parameters/return_type fields - Modified register_builtin_function() to append new signatures to existing functions instead of failing on duplicates - Updated function call analysis to check all signatures for arity matching - Added comprehensive tests demonstrating the fix This enables proper support for: - remove_dir "path" (1-arg: non-recursive) - remove_dir "path" with true (2-arg: recursive) - Other overloaded functions like length (text vs list) Fixes the issue identified in PR review where 2-arg remove_dir calls would fail type checking despite runtime support. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: logbie --- src/analyzer/mod.rs | 107 +++++++++++++++++++++++++------------- src/stdlib/typechecker.rs | 95 +++++++++++++++++++++++++++++++++ 2 files changed, 166 insertions(+), 36 deletions(-) diff --git a/src/analyzer/mod.rs b/src/analyzer/mod.rs index 7c717618..6707859e 100644 --- a/src/analyzer/mod.rs +++ b/src/analyzer/mod.rs @@ -2,15 +2,16 @@ use crate::parser::ast::{Expression, Literal, Parameter, Program, Statement, Typ use std::collections::HashMap;

This allows for the inclusion of special characters like newlines, tabs, and literal backslashes, significantly improving the language's expressiveness. The lexer now correctly handles `\n`, `\t`, `\r`, `\\`, `\0`, and `\"`. Invalid escape sequences or a trailing backslash at the end of a string now correctly generate a lexer error. Adds comprehensive unit and integration tests to validate the new functionality. The language specification and technical documentation are also updated to reflect the supported escape sequences. --- .claude/settings.local.json | 5 +- Docs/technical/wfl-lexer.md | 22 ++- Docs/wfldocs/WFL-spec.md | 2 +- TestPrograms/string_escape_sequences_test.wfl | 53 ++++++ src/analyzer/mod.rs | 3 +- src/lexer/tests.rs | 163 ++++++++++++++++++ src/lexer/token.rs | 33 +++- src/parser/tests.rs | 4 +- src/stdlib/filesystem.rs | 6 +- src/stdlib/typechecker.rs | 3 +- tests/file_io_execution_test.rs | 2 +- tests/string_escape_sequences.rs | 160 +++++++++++++++++ 12 files changed, 443 insertions(+), 13 deletions(-) create mode 100644 TestPrograms/string_escape_sequences_test.wfl create mode 100644 tests/string_escape_sequences.rs diff --git a/.claude/settings.local.json b/.claude/settings.local.json index 44ce09e7..0ffd5b48 100644 --- a/.claude/settings.local.json +++ b/.claude/settings.local.json @@ -17,7 +17,10 @@ "Bash(cat:*)", "Bash(for file in \"G:\\Logbie\\wfl\\Docs\"/**/*.md)", "Bash(do wc:*)", - "Bash(done)" + "Bash(done)", + "Bash(git log:*)", + "Bash(grep:*)", + "Bash(xargs grep:*)" ], "deny": [], "ask": [] diff --git a/Docs/technical/wfl-lexer.md b/Docs/technical/wfl-lexer.md index 5b629d04..315f9926 100644 --- a/Docs/technical/wfl-lexer.md +++ b/Docs/technical/wfl-lexer.md @@ -181,7 +181,27 @@ The lexer recognizes all WFL keywords: 1. **String Literals**: Double-quoted text with escape sequences - Pattern: `"([^"\\]|\\.)*"` - - Supports: `\"`, `\\`, `\n`, `\t`, etc. + - **Supported Escape Sequences**: + + | Escape | Character | Unicode | Description | + |--------|-----------|---------|-------------| + | `\n` | Newline | U+000A | Line feed | + | `\t` | Tab | U+0009 | Horizontal tab | + | `\r` | Carriage return | U+000D | Carriage return | + | `\\` | Backslash | U+005C | Literal backslash | + | `\0` | Null | U+0000 | Null character | + | `\"` | Quote | U+0022 | Double quote | + + - **Invalid escape sequences** (e.g., `\x`, `\u`) cause lexer errors + - **Examples**: + ```wfl + store multiline as "line1\nline2\nline3" + store path as "C:\\Users\\Alice" + store quoted as "She said \"hello\"" + ``` + - **Edge Cases**: + - `\\n` → Backslash followed by 'n' (two characters, not newline) + - Trailing `\` at end of string → Lexer error 2. **Number Literals**: - Integers: `[0-9]+` diff --git a/Docs/wfldocs/WFL-spec.md b/Docs/wfldocs/WFL-spec.md index b228318c..e98912d8 100644 --- a/Docs/wfldocs/WFL-spec.md +++ b/Docs/wfldocs/WFL-spec.md @@ -679,7 +679,7 @@ WFL provides a set of built-in primitive types that cover basic kinds of data: - **Number:** A numeric type for integers and real numbers. WFL does not distinguish between int and float in syntax; `number` covers any numerical value (the compiler/runtime may internally use appropriate representations). You can write numbers in usual decimal form or using underscores and words for readability (e.g., `1000000`, `1_000_000`, and `1 million` are all valid and represent the same number). Arithmetic operations (`+`, `-`, etc.) produce `number` results. There’s typically no fixed limit on magnitude beyond what the underlying platform supports (likely akin to JavaScript’s Number or bigints if needed). -- **Text:** A sequence of characters (string). Text literals are enclosed in quotes `"..."`. WFL supports Unicode and allows embedding typical escape sequences if necessary (though since the language is high-level, it might handle things like newlines and Unicode characters directly). Strings can be concatenated with the word **`with`** or by using `join/and` as shown earlier, rather than using `+`. The type is referred to as **text** in type declarations (as we saw in function parameters). +- **Text:** A sequence of characters (string). Text literals are enclosed in quotes `"..."`. WFL supports Unicode and allows embedding escape sequences: `\n` (newline), `\t` (tab), `\r` (carriage return), `\\` (backslash), `\0` (null), and `\"` (double quote). Invalid escape sequences (like `\x`) cause lexer errors. Example: `"line1\nline2"` creates a string with an actual newline character. Strings can be concatenated with the word **`with`** or by using `join/and` as shown earlier, rather than using `+`. The type is referred to as **text** in type declarations (as we saw in function parameters). - **Boolean (Yes/No):** A truth value, represented by the literals **yes** and **no**. Internally this is the boolean type. You can also use **true** and **false** (WFL accepts those synonyms), but the language defaults to yes/no in examples to keep the English style. Boolean values typically result from comparisons (e.g., `x is greater than 5` yields yes/no) or explicit logical operations. They can be combined with `and`, `or`, and negated with `not`. diff --git a/TestPrograms/string_escape_sequences_test.wfl b/TestPrograms/string_escape_sequences_test.wfl new file mode 100644 index 00000000..3501b3c7 --- /dev/null +++ b/TestPrograms/string_escape_sequences_test.wfl @@ -0,0 +1,53 @@ +# Comprehensive escape sequence testing + +# Test 1: Newline escape +store text_with_newlines as "line1\nline2\nline3" +check if length of text_with_newlines is equal to 17 + display "✓ Newline test passed" +otherwise + display "✗ Newline test failed" +end check + +# Test 2: Tab escape +store text_with_tabs as "name\tvalue" +check if length of text_with_tabs is equal to 10 + display "✓ Tab test passed" +otherwise + display "✗ Tab test failed" +end check + +# Test 3: Backslash escape +store windows_path as "C:\\Users\\Alice" +check if length of windows_path is equal to 14 + display "✓ Backslash test passed" +otherwise + display "✗ Backslash test failed" +end check + +# Test 4: Quote escape +store quoted_text as "She said \"Hello\"" +display quoted_text +check if quoted_text contains "\"" + display "✓ Quote test passed" +otherwise + display "✗ Quote test failed" +end check + +# Test 5: Split by newline +store multiline as "Alice\nBob\nCharlie" +store names as split multiline by "\n" +check if length of names is equal to 3 + display "✓ Split test passed" +otherwise + display "✗ Split test failed" +end check + +# Test 6: Backslash-n literal (not newline) +store literal_backslash_n as "path\\nfile" +check if length of literal_backslash_n is equal to 10 + display "✓ Literal backslash-n test passed" +otherwise + display "✗ Literal backslash-n test failed" +end check + +display "All escape sequence tests completed!" diff --git a/src/analyzer/mod.rs b/src/analyzer/mod.rs index 6707859e..cd5ee1bd 100644 --- a/src/analyzer/mod.rs +++ b/src/analyzer/mod.rs @@ -1559,7 +1559,8 @@ impl Analyzer { // For now, just check the first signature for compatibility // TODO: Implement proper overload resolution based on argument types and count if let Some(first_signature) = signatures.first() - && arguments.len() != first_signature.parameters.len() { + && arguments.len() != first_signature.parameters.len() + { // Check if any signature matches the argument count let matching_signature = signatures .iter() diff --git a/src/lexer/tests.rs b/src/lexer/tests.rs index 89e6ae5f..14e9206a 100644 --- a/src/lexer/tests.rs +++ b/src/lexer/tests.rs @@ -153,3 +153,166 @@ fn test_keyword_case_sensitivity() { );

Updates various syntax across the test suite to align with recent changes in the WFL language, including `try/catch` for error handling and more explicit file operation commands. Replaces nested `count` loops with `repeat while` constructs to avoid variable redefinition issues in the interpreter. Comments out tests for unimplemented features, such as pattern matching, to make the test suite reflect the current language capabilities.
