[xtopdf] Publish Delimiter-Separated Values (DSV data) to PDF (Python)

2016-12-17T19:08:33-08:00

Python recipe 580736 by Vasudev Ram (commandline, csv, data, files, formats, pdf, pdf_generation, python, tsv, utilities, xtopdf).

This recipe shows how to publish delimiter-separated values (a commonly used tabular data format) to PDF, using the xtopdf toolkit for PDF creation. It lets the user specify the delimiter via one of two command-line options - an ASCII code or an ASCII character. As Unix filters tend to do, it can operate either on standard input or on input filenames given as command-line arguments. In the case of multiple inputs via files, each input goes to a separate PDF output file.

A simple text file pager in Python (Python)

2017-02-10T21:34:45-08:00

Python recipe 580755 by Vasudev Ram (command, commandline, pagination, paging, python, text, utilities, windows).

This recipe shows how to create a simple text file pager in Python. It allows you to view text content a page at a time (with a user-definable number of lines per page). Like standard Unix utilities, it can either take a text file name as a command-line argument, or can read the text from its standard input, which can be redirected to come from a file, or to come from a pipe. The recipe is for Windows only, though, since it uses the msvcrt.getch() function, which is Windows-specific. However, the recipe can be modified to work on Unix by using things like tty, curses, termios, cbreak, etc.

Give Python code a web plus command-line interface with hug (Python)

2017-01-05T16:57:15-08:00

Python recipe 580742 by Vasudev Ram (cli, commandline, hug, library, python, python3, user_interface, web, web_server).

This recipe shows how to take a Python function and wrap it with both a web and a command-line interface, somewhat easily, using the hug Python library. The example used shows how to wrap a function that uses the psutil library to get information on disk partitions. So you can see the disk partition info either via the web browser or the command line. The code for the recipe is shown below. It is also possible to wrap multiple functions in the same Python file, and expose all of them via both the web and the command-line.

More information and multiple sample outputs are available here:

Simple directory list command with filename wildcard support (Python)

2016-12-02T20:52:56-08:00

Python recipe 580724 by Vasudev Ram (commandline, directory, file, filesystem, python, utilities).

This recipe shows a simple directory listing program. It can accept multiple command-line arguments specifying filenames. These filenames can include wildcard characters like * (asterisk) and ? (question mark), as is common in OS command shells like bash (Unix) and CMD (Windows). Tested on Windows but should work on Unix too, since it uses no OS-specific functions, or rather, it does use them, but that happens under the hood, within the libraries used.

Process Delimiter-Separated Values data with Python (Python)

2016-11-24T23:57:35-08:00

Python recipe 580722 by Vasudev Ram (command, commandline, data, dsv, file, python, utilities, utility).

This recipe shows how to read and process delimiter-separated values (DSV) data with a Python command-line program. It provides two ways of specifying the delimiter character, by an ASCII character or an ASCII code, which makes it more flexible than allowing only a character. It allows the DSV data to be specified as one or more filenames on the command line, or given via the standard input of the program.

Extract Multiple TAR Files & Directories (Python)

2012-07-04T00:57:37-07:00

Python recipe 578191 by Stephen Chappell (archive, commandline, old, tarfile).

Related to the popular recipe 442503, this command-line program takes multiple TAR files or directories and can extract them in a batch operation. This is committed for archival to be run under Python 2.5 or later versions.

Linux to Windows (Python)

2012-07-04T01:18:50-07:00

Python recipe 578192 by Stephen Chappell (archive, commandline, old, utility).

When trying to work with Linux archive downloaded onto Windows, sometimes it is helpful to untar all found archives, give extension-less files the "txt" extension, and convert text files to Windows line endings (\r\n), and that is just what this program is designed to accomplish. This is committed for archival to be run under Python 2.5 or later versions.

FSM 2.5 Reader (Python)

2011-04-06T03:02:57-07:00

Python recipe 577639 by Stephen Chappell (commandline, file_io, file_share, messenger, network, workaround).

For those who would want to search the message logs produced by recipe 577638, this program provides a command-line solution to searching messages according to their authors. If this program is placed in the message directory, the program may be executed on the command-line with the author's name as an argument. If and when the program is executed without an argument, usage information is shown on the screen before exiting. If an author was not found, the author's name is printed stating that nothing could be found. If a matching file was found, all timestamps and messages will be displayed that could be decoded correctly.

If there are any recommendation for this recipe or if anyone wishes to down-vote this recipe, please provide corrective criticism showing the the program's faults and give suggestions on how you would fix any problems that it might have.

Directory Size (Console) (Python)

2011-02-09T13:29:56-08:00

Python recipe 577566 by Stephen Chappell (commandline, directory, sizeof, tree).

Have you ever wanted to find out how much room a particular directory was taking up on your hard drive? A roommate of mine in college was having trouble keeping track of where his hard drive space is going, so the following program provided a solution that allows a brief overview of a directory's size along with all of its children. A tree view is printed out in ASCII characters showing the relationship of each directory along with its size in a format easily readable to humans. The output can always be redirected to a text file if it needs to be saved for viewing later on.

Better quote module for bash shells (Python)

2010-12-03T09:16:45-08:00

Python recipe 577483 by Kevin L. Sitze (bash, command, commandline, escape, logging, quote, script, shell).

This Python module quotes a Python string so that it will be treated as a single argument to commands ran via os.system() (assuming bash is the underlying shell). In other words, this module makes arbitrary strings "command line safe" (for bash command lines anyway, YMMV if you're using Windows or one of the (less fine) posix shells).

argdeclare: declarative interface to argparse (Python)

2010-03-02T00:05:40-08:00

Python recipe 576935 by Shakeeb Alireza (argparse, cmdln, commandline, getopt, metaclass, option). Revision 5.

This is an implementation of the interface provided by the cmdln module but using argparse to provide the option/arg heavy parsing.

An example of usage is provided in the test function, which should produce the following from the command line:

$ python argdeclare.py --help

usage: argdeclare.py [-h] [-v] {uninstall,install,delete} ...

a description of the test app

optional arguments:
  -h, --help            show this help message and exit
  -v, --version         show program's version number and exit

    install             help text for install subcmd
    uninstall           help text for uninstall subcmd

$ python argdeclare.py install --help
