Minimum Intrusion Grid (MiG) Utilities library

Project description

https://travis-ci.org/rasmunk/mig_utils.svg?branch=master

A Minimum Intrusion Grid(MiG) utilities python library: It includes the mig.io module that provides access to MiG Sharelinks through python by wrapping around (https://github.com/althonos/fs.sshfs) for sshfs connections.

Installation

Installation from pypi

pip install mig-utils

Installation from a local git repository

cd mig-utils
pip install .

IO Example

ERDA (https://erda.dk) sharelink access with python3 example. A likewise sharelink class (IdmcShare) exists for IDMC (https://idmc.dk)

# First import the class that gives you access to the share in question*
from mig.io import ErdaShare

# Initialize sharelink
share = ErdaShare('SHARELINKID')

# List files/dirs in share
print(share.list())

# Read file directly as string
print(share.read('tmp'))

# Read file directly as binary
print(str(share.read_binary('tmp')))

# Get a _io.TextIOWrapper object with automatic close
with share.open('tmp', 'r') as tmp:
    print(tmp.read())

# Get a default _io.TextIOWrapper object with manual lifetime
file = share.open('tmp', 'r')
print(file.read())
file.close()

# Writing strings to a file
test_string = "Hello There"
test_num = 42342342
test_float = 3434.231

with share.open('write_test', 'w') as w_file:
    w_file.write(test_string)
    w_file.write(str(test_num))
    w_file.write(str(test_float))

# Writing bytes to a file
test_binary = b'Hello again'
test_b_num = (255).to_bytes(1, byteorder=sys.byteorder)
with share.open('binary_test', 'wb') as b_file:
    b_file.write(test_binary)
    b_file.write(test_b_num)

# Removing files, likewise for dirs by using share.removedir(path)
share.remove('writes_test')
share.remove('binary_test')
