pygitgrab

grab only certain information from remote git repo and store them local

general information

pygitgrab is not intended to be a replacement for git and it's capabilities. pygitgrab will not do housekeeping, meaning maintaing the local directory content like syncing or such a like. in case remote files or folders are dropped it is required to clean local folders manually.

installation

the module is on pypi and can be installed with pip

run from cmd line

[python3 -m] pygitgrab -h

python3 -m pygitgrab -u user_name # user_name is optional, will prompt for password

# use credits file for github authentication 
python3 -m pygitgrab -c 

# use other .pygg files, here web.pygg, and cntrl.pygg
python3 -m pygitgrab -u user_name -f web -f cntrl   

# use remote .pygg files, use ref for selecting the github tag
# if ref=master fails try ref=main or any valid tag, no detail error message from github
python3 -m pygitgrab -u user_name -url https://github.com/kr-g/pygitgrab/cntrl.pygg?ref=master

github offers downloading for unauthenticed users only within certain rate limits https://developer.github.com/v3/rate_limit/. in case downloading a bunch of serveral project files it is required to authenticate. (see also deprecation note of GitHub at the end of this document)

pygg.cfg structure

pygitgrab loads a pygg.cfg config file from the current directory to perform the required steps. the structure is as following:

[repo_alias]
# url to repo
url=https://github.com/_owner_name_/_repo_name_
# optional version to check out, defaults to 'master'
tag=master
# optional destination folder given, defaults to 'repo_alias' (name of this section in the config file)
# pull_alias is just a name for the pull task
pull_alias="*.py", "new_folder"
# sample for pulling a license and store them at a different place
license="LICENSE.md", "LICENSE/a_license.MD"

pygitgrab will create the directory structure as found in the remote git repo when pattern matching is used.

pygitgrab uses python configparser. general information regarding the syntax can be found there.

other pygg files

when calling with parameter -f cfgfile the configuration is read from there instead of pygg.cfg config file. if a file extension is missing an extension .pygg is added as default.

cmd line parameter

usage: [python3 -m] pygitgrab [options]

grab files from remote git repo.

optional arguments:
  -h, --help            show this help message and exit
  -v, --version         show version info and exit
  -V, --verbose         show more info
  -L, --license         show license info and exit
  -s, --simulate        dry run, do not download files
  -f FILE, --file FILE  name of pygg file to read, adds as '.pygg' extension if missing
  -url URL              name of remote pygg file on github to read, adds as '.pygg' extension if missing
  -u [USER], --user [USER]
                        authenticate with user, no user for prompt. create a personal access token in your github settings instead of using a password.
                        unauthenticated users have a lower rate for downloading from github. https://developer.github.com/v3/rate_limit/
  -c [CREDITS], --credits [CREDITS]
                        read user and personal token from a file instead of prompting. make sure to put the file not in git controlled directory, (default:
                        '~/pygg.credits.txt')
  -nc, -ano, --no-credits, --anonymous
                        don't use the main credits file '~/.pygg_credits'
  -irepo INSPECT_REPO, --inspect-repo INSPECT_REPO
                        read repo meta data
  -idir INSPECT_DIR [INSPECT_DIR ...], --inspect-dir INSPECT_DIR [INSPECT_DIR ...]
                        read repo directory content
  -itags INSPECT_TAGS, --inspect-tags INSPECT_TAGS
                        read repo tags

3rd party licenses

when you move 3rd party license information into the special folder 'LICENSE' the cmd python3 -m pygitgrab -L will produce a summary of all found licences together with a 'LICENSE' file found in the current directory. use as python3 -m pygitgrab -L > LICENSES to produce a summary plain text file.

limitations

works only with github as backend.

deprecation of user and password authentication

github recently announced to discontinue user/password authentication soon.

use a personal access token instead of a password.

create your personal access token under GitHub developer settings as described in the help for creating a personal access token

the minimum required scope(s) of the token is public_repo

using a credits file instead of manual authentication

with the option -c or --credits pygitgrab reads the github user credits from a file.

this defaults to ~/pygg.credits.txt in the home directory if not specified. dont put it under a git controlled directory to prevent exposing your sensitive data.

the file itself should have 2 lines the following structure:

user-name
user-token

it can have blank lines at any place.

user local credits file

if no parameter -c is given pygitgrab reads the credits from ~/.pygg_credits by default.

this default behaviour can be disabled by the parameter --anonymous where pygitgrab downloads without any user credit information.
