* '''Easy user documentation''': I'm a firm believer that it is necessary to add some user documentation, even minimal, to any program. An easy way to do this is to simply generate such documentation from the "help" message, as long as it is "properly" formatted (see [http://www.gnu.org/s/help2man/ help2man]). The following commands work for any programming language: | |||
<nowiki> | |||
help2man -o myprogram.man ./myprogram | |||
man ./myprogram.man | |||
groff -mandoc myprogram.man > myprogram.ps | |||
ps2pdf myprogram.ps myprogram.pdf | |||
</nowiki> | |||

* '''Bash''': sometimes it's easier to write a script in bash rather than in python. This is especially the case when one wants to use pipes, eg. <nowiki>zcat data.txt.gz | awk '{print $1}'</nowiki>, or when one wants to use a [http://en.wikipedia.org/wiki/Glob_%28programming%29 glob] to pass multiple files to the script, eg. <nowiki>./myscript.bash -i "input*.txt"</nowiki>. | |||

Typical templates for Python scripts, C++ programs and othersIt is always rewarding on the long term to start any piece of computer software with a minimum amount of generic code (verbose, command-line options, help message, license, etc). But it's a pain to write all this every time, right? So below are my typical templates for any Python script, C++ program, Beamer presentation, Bash script, etc.
