[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.

Read CSV with D and write it to PDF with Python (Python)

2016-10-26T17:49:00-07:00

Python recipe 580710 by Vasudev Ram (conversion, csv, data, files, formats, pdf, pdf_generation, xtopdf).

This recipe shows how to read data from a CSV file with a D program and write that data to a PDF file with a Python program - all in a single command-line invocation (after writing the individual programs, of course).

It requires the xtopdf toolkit, which you can get from:

https://bitbucket.org/vasudevram/xtopdf

Instructions for installing xtopdf:

xtopdf in turn requires the open source version of the ReportLab toolkit, which you can get from:

http://www.reportlab.com/ftp (http://www.reportlab.com/ftp/reportlab-1.21.1.tar.gz)

It also requires the DMD compiler to compile the D program - this was the version used:

DMD32 D Compiler v2.071.2

This allows you to hold on to your csv in a dict form, do lookups and modifications, and also write it in a preserved order. You can also change which column you want to be your lookup column (making sure that there is a unique id for every row of that column. In my example of usage, it assumes that both classes are contained withing the same file named 'CustomDictReader.py'

Populate SQL tables from CSV data files (Python)

2011-02-02T21:21:49-08:00

Python recipe 577559 by James Mills (conversion, csv, data, python, sql).

Just a quick recipe I developed a few years ago that I thought might be useful to others. Basically it takes as input a data file with comma separated values (CSV) and translates this into a series of SQL "INSERT" statements allowing you to then feed this into MySQL, SQLite, or any other database.

Example Usage:

$ cat cars.csv Year,Make,Model,Length 1997,Ford,E350,2.34 2000,Mercury,Cougar,2.38

$ sqlite3 cars.db "CREATE TABLE cars (Year, Make, Model, Length)"

$ ./csv2sql.py cars.csv | sqlite3 cars.db

$ sqlite3 cars.db "SELECT * FROM cars" 1997|Ford|E350|2.34 2000|Mercury|Cougar|2.38

Enjoy! Feedback welcome!

cheers James Mills / prologic
