Unified diff python parsing/metadata extraction library - matiasb/python-unidiff

difflib.unified_diff(a, b, fromfile='', tofile='', fromfiledate='', tofiledate='', n=3, lineterm='\n')[source]¶

Return a delta: the difference between a and b (lists of strings). ... Return one of the two sequences that generated an ndiff delta. ... For two lists of strings, return a delta in unified diff format.

According to the documentation, this module provides classes and functions for comparing sequences. Furthermore, various output formats are available [1]. While inspecting the module, the unified_diff...

Unified diffs are a compact way of showing just the lines that have changed plus a few lines of context. The changes are shown in an inline style (instead of separate before/after blocks).

Context diff format has a header for filenames and modification times. Any or all of these may be specified using strings for from_file, to_file, from_file_date, and to_file_date. fn unified_diff<T: Sequence>(first_sequence: &T, second_sequence: &T, from_file: &str, to_file: &str, from_file_date: &str, to_file_date: &str, n: usize) -> Vec<String>

July 1, 2023 - DiffLib is a Hack library for creating and parsing diffs. Diffs can be created between any two sequences of items. Additional helpers (such as support for unified diffs, and colored diffs) are provided for string diffs.

Diffs are configured with Unified (or ContextDiff) structures, and can be output to an io.Writer or returned as a string. diff := difflib.UnifiedDiff{ A: difflib.SplitLines("foo\nbar\n"), B: difflib.SplitLines("foo\nbaz\n"), FromFile: "Original", ToFile: "Current", Context: 3, } text, _ := difflib.GetUnifiedDiffString(diff) fmt.Printf(text)

February 22, 2024 - def _check_types(a, b, *args): # Checking types is weird, but the alternative is garbled output when # someone passes mixed bytes and str to {unified,context}_diff(). E.g. # without this check, passing filenames as bytes results in output like # --- b'oldfile.txt' # +++ b'newfile.txt' # because of how str.format() incorporates bytes objects.

A JavaScript module which provides classes and functions for comparing sequences. It can be used for example, for comparing files, and can produce difference information in various formats, including context and unified diffs.
