diff2patch

A python tool to compare two directorys and composes a survey-list with all found differences. These can then used to:

• compose a patch with all different and in dir2 new files. The content can be output:
  • as simple directory tree
  • as archive of types: lzma, gzip, bzip2, zip, tar
• give a report in different forms:
  • printed to terminal
  • written to a text-file
  • both

The file/directory count and the expected patch size is also calculated.

Dependencys

• python 3.10 or newer

Optional

For terminal colors in info messages: With early Windows 10 and before could it be necessary to change a few config settings to make it work.

Colors just a fancfull addition and the programm works without it. Some people might want it. There are also other ways like ansicon or the use of Windows terminal, where ANSI already integrated is. (needs possibly terminal-setup changes)

Usage

Command line parameter overview

diff2patch.py [-h] (-d | -a {xz,gz,bz2,zip,tar} | -r {console,file,both}) [-o OUTPATH]
[-i] [-n] [-l] [--version] dir1 dir2

Generates a diff-patch or diff-overview of two given directory structures.

positional arguments:
dir1                    Dir 1/left directory
dir2                    Dir 2/right directory

Mutual exclusive options (One must be given):
-d, --dir               Outputs the diff as a directory structure.
-a, --archive {xz,gz,bz2,zip,tar}
                        Outputs the diff as archive of given type.
-r, --report {console,file,both}
                        Outputs the diff as comparison report to given target.

Options:
-o, --outpath OUTPATH   Output path name for the diff result. Defaults to the parent dir
                        of <dir2> if not given.
-i, --indepth           Compares the files content instead statinfos like size, date of
                        last change.
-n, --no_log            Deactivates the use of a logfile in the script path.
-l, --loglevel          Set minimum log-level for the console. Default is `notable`. Use
                        `warning` or higher to reduce output.         
--version               show program\'s version number and exit
-h, --help              show this help message and exit

Example CLI usage

Compares the two given dirs and places the difference to the default ouput directory. python3 diff2patch.py -d /home/user/example/dir_v0.1 /home/user/example/dir_v0.2

Compares two dirs, copies the difference to a dir und constructs a gzip archive from it. This is then placed in the given output path. python3 diff2patch.py -a gz ~/example/dir_v0.1 ~/example/dir_v0.2 -o ~/outdir

Compares and prints the found difference to the console window. python3 diff2patch.py -r console /some/path/dir_1 /some/path/dir_2
