Examples on file operations

Directories

• Getting current working directory
• Defining temporary files and temporary folders
• Getting the directory and the basename of files

from rlike import *
getwd()

'/home/runner/work/rlike/rlike/docs'

x = tempdir()
x

'/tmp/tmp4dldswsq'

x = tempfile(pattern = 'hello', fileext = '.txt')
x

'/tmp/tmpzk38vobp/helloq93lcfea.txt'

dirname(x)

'/tmp/tmpzk38vobp'

basename(x)

'helloq93lcfea.txt'

Listing / paths / extensions

• Listing files in a directory
• Constructing paths to files
• Check if files exist

from rlike import *
x = list_files(pattern = ".txt", recursive = True)
x = list_files(recursive = False)
file_exists(x)

[True, True, True, True, True, True, True, True, True, True, True, True, True, True, True, True, True, True, True, True]

x = file_path(getwd(), "subfolder", ["file1.txt", "file2.txt"])
file_ext(x)

['.txt', '.txt']

file_path_sans_ext(x)

['/home/runner/work/rlike/rlike/docs/subfolder/file1', '/home/runner/work/rlike/rlike/docs/subfolder/file2']

Removing / copying

• Removing files and directories

folder = tempdir()
x = tempfile(pattern = 'hello_x', fileext = '.txt', tmpdir = folder)
writeLines(text = "hi", con = x)

'/tmp/tmp2yyue8l8/hello_x67np7itg.txt'

y = tempfile(pattern = 'hello_y', fileext = '.txt', tmpdir = folder)
writeLines(text = "hi again", con = y)

'/tmp/tmp2yyue8l8/hello_ytamcheub.txt'

file_exists([x, y])

[True, True]

file_copy(x, y)

'/tmp/tmp2yyue8l8/hello_ytamcheub.txt'

readLines(y)

['hi']

file_remove([x, y])

[None, None]

unlink(folder)

• Location of installed python module

x = system_file(package = 'rlike') 
x

'/home/runner/.virtualenvs/r-reticulate/lib/python3.12/site-packages/rlike'
