WinFileScanner - Advanced File Search and Enumeration Library
============================================
Code:
> Overview:
WinFileScanner is a high-performance file system scanning library designed for
complex pattern matching, exclusion filters, and recursive directory traversal.
Written in Nim for maximum efficiency, it includes a comprehensive 'Text File
Content Plugin' for advanced text analysis, encoding detection, and file
comparison directly within your applications or Inno Setup installers.
> Specifications:
- Version : v4.0
- Author : BLACKFIRE69
- Language : Nim (v2.2.8)
- Compatibility : Windows XP or later
- Thread Safety : Handle-based (Thread-safe per handle)
Code:
> Key Features:
- Multi-pattern file matching with wildcards.
- Regular expression pattern matching (v3.1+).
- Input validation with user-friendly error messages (v3.1+).
- Exclude pattern support for fine-grained scanning.
- Recursive directory scanning with high performance.
- CRC32 hash calculation (optional) for file verification.
- Hidden/system file filtering options.
- Multiple result and output format types (v3.2+).
- Directory enumeration and result persistence to file.
- Memory-efficient handle-based result storage.
> Text Analysis Plugin Features:
- Encoding detection (ANSI, UTF-8, UTF-8 BOM, UTF-16 LE/BE).
- Text statistics (lines, words, chars, comments, blanks).
- Text search (simple, regex, multi-pattern, contextual).
- Tokenization (words, lines, custom delimiters, frequency).
- Content splitting (delimiter, quote-aware, key-value, groups).
- File comparison (LCS-based diff).
- Save results directly to file.

> Builds: optimized for speed, not size.
1. WinFileScanner_clang.dll
Size: 153 KB, Clang backend: v22.1.0
2. WinFileScanner_gcc.dll
Size: 202 KB, GCC backend : v15.2.0
3. WinFileScanner_msvc.dll
Size: 213 KB, MSVC backend : v18.3.2
Code:
> Patterns: separated by pipe (|) character.
1. WILDCARDS (default):
*.exe - All .exe files
*.exe|*.dll - All .exe and .dll files
game*.dll - Files starting with "game" ending with .dll
20??_cfg.ini - ? matches single character (2023_cfg.ini, 2024_cfg.ini)
images?\png\* - Matches images1\png\*, images2\png\*, etc.
2. FILE INCLUDES (@<file>):
@masks.txt - Load patterns from file (one per line)
@"C:\my masks.txt" - Quoted path for spaces
@".\local.txt" - Relative path
3. REGULAR EXPRESSIONS ($"pattern"):
$"^setup.*\.exe$" - Files starting with "setup" ending with .exe
$".*\d{4}.*" - Files containing 4 consecutive digits
$"^[^.]+$" - Files without extension
4. COMBINED:
*.dll|$"^setup.*\.exe$"|@C:\masks.txt
- Quick Start Examples -
Code:
[ File Search ]
---------------
{Code]
var
FindHandle: Longint;
i: Integer;
begin
// Search for all .exe and .dll files recursively
FindHandle := wfs_FindFilesEx(
'C:\MyFolder', // Search path
'', // Destination path (empty = same as search path)
'*.exe|*.dll', // Include patterns
'', // Exclude patterns
frfFullPath, // Result format: full paths
ftSFV, // List output format: <File> <Hash>
True, // Recursive
False, // Include hidden files
False, // Include system files
False, // Don't enumerate directories
True); // Calculate CRC32 hash
if FindHandle > 0 then
begin
for i := 0 to wfs_FileCount(FindHandle) - 1 do
Log(wfs_PickFile(FindHandle, i));
end;
wfs_FindFree(FindHandle); // IMPORTANT: Always free the handle!
end;
Code:
[ Text Analysis Plugin ]
------------------------
{Code]
var
hText, hSearch: Longint;
i: Integer;
begin
// Load a text file with "//" and "#" as comment prefixes
hText := wfs_TextOpen('C:\src\main.pas', '//|#');
if hText > 0 then
begin
Log('Lines: ' + IntToStr(wfs_TextStatTotalLines(hText)));
Log('Words: ' + IntToStr(wfs_TextStatTotalWords(hText)));
Log('Encoding: ' + wfs_TextGetEncodingStr(hText));
// Search for a pattern
hSearch := wfs_TextSearch(hText, 'function', False, True);
Log('Functions found: ' + IntToStr(wfs_TextSearchCount(hSearch)));
wfs_TextSearchFree(hSearch);
wfs_TextFree(hText); // Always free the handle!
end;
end;
