Python – What are the benefits of using IronPython over IronRuby or F#

%fironpythonironruby

Well aware that DLR is here!! I have recently reading up on all of these and was wondering if there were any specific benefits of using one language over another?

For example performance benefits! and available functionality through standard libaries!!

The answer is "depends".

F# is great if you need to functional programming is used extensively by Academics that need its pure computing power to get something done.

IronPython and IronRuby is great for being able to create applications that run on the CLR because they give you the .NET goodness with the speed of writing Python or Ruby. I don't think that any of these is more preferable to another without it being in a proper context

Python – Current standard compliance level of IronPython & IronRuby

The following sites usually have updates as to how their 'compliance' is progressing:

IronRuby -

In fact from the IronRuby site -

"We showed IronRuby dispatching some static and dynamic Rails requests at RailsConf this year. We are running the RubySpecs to measure our conformity with Ruby and we're passing the core specs at a 71% rate (12026 / 16793 expectations for RubySpec core)."

Bash – Find and Replace Inside a Text File from a Bash Command

The easiest way is to use sed (or perl):

sed -i -e 's/abc/XYZ/g' /tmp/file.txt

Which will invoke sed to do an in-place edit due to the -i option. This can be called from bash.

If you really really want to use just bash, then the following can work:

while read a; do
    echo ${a//abc/XYZ}
done < /tmp/file.txt > /tmp/file.txt.t
mv /tmp/file.txt{.t,}

This loops over each line, doing a substitution, and writing to a temporary file (don't want to clobber the input). The move at the end just moves temporary to the original name.

For Mac users:

sed -i '' 's/abc/XYZ/g' /tmp/file.txt (See the comment below why)
