Subject: [pm-h] simple perl directory+file task
Message-ID: <20121002150044.GB18883@gospelbroadcasting.org>

I am looking forward to the meeting on the 11th.  It is simple tasks
of the following sort which I hope the presentation is going to teach
me how best to approach:

--------------------------
SITUATION: A directory "datafiles/" contains files named "red.doc",
"green.dat", "yellow.tex", "blue.txt", etc.

NEED:  Open each file in the directory, and append to the end of each
file the file name, so that file "red.doc" reads:

     <existing text, if any>
     red.doc

file "yellow.tex" reads:

     <existing text>
     yellow.tex

and so forth. 
--------------------------

Of course, the next step is recursion into sub-directories.  From my
reading I think I see how to handle recursion, but obtaining the
filename and stepping through a directory is the immediate hurdle.  

It seems to me that the books and tutorials typically do not spend
enough time explaining the fundamental concepts.

Hi Russell,

You might review the docs for find2perl[1] and also examining the output of

  find2perl . -type f -print

Building your project in perl will give you a lot of added flexibility but just because you have a swiss army chainsaw doesn't mean every problem is a... thing you would drive into a piece of wood with a chainsaw.  (Doesn't just trip off the tongue does it?)

Consider

  $ cat > /tmp/name_me <<'END'
  #!/bin/bash
  echo $(basename $1) >> $1
  END
  $ chmod 755 /tmp/name_me
  $ cd datafiles
  $ find . -type f -print | xargs -n 1 /tmp/name_me

and your task is also accomplished.  Perl can do everything bash and sed can (and awk too but use perl instead) but sometimes you don't need perl when simpler tools will do.

  Enjoy,
  -ljr

Agreed.  My tool of preference is Emacs.

Gratitude and thanks, Lanny.  Your solution saved the day, getting me
past the immediate impasse.  Chainsaw, hand saw, or axe -- in the end,
all that matters is that the tree is felled.  But this was but one of
many trees which I must fell, so other impasses are likely.

I am attempting to resurrect a project which I was forced to set aside
in mid-stream several years ago.  That project necessitates recursion
to perform a series of simple, identical operations on several sets of
data, each of which involves a search-and-replace operation on
literally hundreds of files.

Because of the repetition, my approach back then was to create a set
of Perl scripts; I found it easier to utilize a sequence of about a
dozen simple scripts, rather than try to do everything in one or two
complex scripts.  And the script-writing and processing was going
well, until I was forced to set aside the project.

So, I am reading the latest edition of "Learning Perl" (a few years
ago, I read two of the earlier editions, plus portions of the other
O'Reilly Perl books), trying this time to get a better grasp of the
fundamentals.

Subject: [pm-h] ode blogging (perl script)
Message-ID: <20121010162548.GA3881@gospelbroadcasting.org>

I am considering installing and learning to use the Perl blogging
engine script "ode", first in the LAN and later, on a remote host for
public access.

My last blogging experience was with WordPress.  I started with the
first release, but as releases of updated versions and patches became
more frequent, WordPress quickly became a very demanding "religion".
In particular, I could not tolerate the inability of WordPress to
automatically transfer customizations and configuration settings from
one release to the next.

Ode assumes that the blogger is going to use his normal text editor to
produce plain text, then allow ode to utilize "markdown" to convert
plain-text to HTML.  However, ode allows the direct import of HTML.

My intention is to write posts in LaTeX markup (which is how I write
everything nowadays) and convert from LaTeX to HTML for the blog.
Several years ago, I was using HeVeA to convert LaTeX to HTML, but
with the advent of HTML5 and CSS, that may not be practical today. 

Recommendations?  Warnings?

These days WordPress is pretty good about keeping your customizations and stuff?
consistent across upgrades. ?And there's always wordpress.com if you don't want to?
self host. ?Wordpress.com even supports LaTeX?

http://en.support.wordpress.com/latex/

I personally write most of blog posts in Markdown, save them to github and?
use a tiny little?perl script to turn them into HTML for posting on my original blog.

You can check out my repository for this work here:

https://github.com/mrallen1/P5P-Weekly

This works pretty nicely - then I have a form that looks reasonably nice as plain?
text and as HTML without doing any extra work. ?One thing that's nice about?
Markdown is that even if it isn't rendered it's a pretty clean reading experience.

I use ikiwiki on my site with markdown which updates the HTML output
using a repository hook whenever I push to the repository.

I was able to use ikiwiki with a plugin for LaTeX that generates HTML
using TeX4ht which worked pretty well for uploading notes with many
equations <http://ikiwiki.info/plugins/contrib/tex4ht/>. TeX4ht's output
can be configured, but I haven't had any reason to do so yet.

Found it in a message posted 29 September:

"As usual, we will meet at 3131 W. Alabama St. The presentation starts
at 7pm. We'll gather in the lobby on top of the parking garage between
6:40pm and 7pm, and go to the meeting from there."

I've gotten a suggestion for a topic off-list.

Would anyone be interested in a group discussion of favorite tools or
tricks for automating daily tasks?

The idea is that several of us would show our favorites and we would
discuss them as a group.

Opinions? Other ideas?

The next Houston.pm meeting is on November 8, a week from this Thursday.
This month's meeting will be a little different. I will be leading a
discussion of tools and tricks for automating daily tasks.

The quality of the meeting will depend on you. Everyone should bring
their favorite Perl snippets, quick scripts, and one-liners. The only
theme is "Getting Things Done". If the code solves a problem for you,
it is a subject for the meeting.

As usual, we will meet at 3131 W. Alabama St. in the lobby area between
6:40pm and 7pm on Thursday night. We'll go up to the conference room at
7pm. Parking on top of the parking garage is free.

I look forward to seeing you there.
