Sed: add space into an regular expression

I am writing a script that compresses web files in order to reduce the size of a site and load on the server. After stripping out leading and trailing spaces I remove newlines and this causes problem with PHP files, since I get something like this:

<?php...

where ... represents some PHP code. This is not valid. The following is needed - note the space before ...:

<?php ...

I am writing a script in Bash shell using sed for string conversions. I am sure Perl, Python or other scripting languages would be a better choice, but I am not familiar with them - even with sed I only scratch the surface. I did not know how to insert a space into an regex with sed, so I came up with the following solution:

sed \

-e "s/<?php[^ ]/jabudabu&/g" \

-e "s/jabudabu<?php/<?php\ /g" \

-e "s/<?[^(php) ]/jabudabu&/g" \

-e "s/jabudabu<?/<?\ /g"

Dobra zadeva, če moraš skrbeti za več računalnikov in težko spremljaš, kje moraš kaj posodobiti.

Work fewer hours

Daniel Lemire wrote an interesting post on his blog. In few words:

• working more has no direct influence on academic performance
• working longer hours pollute more

Nove slike

Ravno sem dodal nekaj novih slik v družinski album pri Pisasi. Dodajam tudi oznake (ang. tags) in pa lokacije nastanka posameznih slik. Slednje mi je še posebej všeč, saj je zadeva povezana z Google maps - primer.

Using Sweave with LyX

It has been a while since I managed to configure LyX (a great "word processor") to work with Sweave (literate programming using LaTeX and R - wikipedia page). The paper describing the whole thing will probably be published in the next issue of Rnews. Since, I received some inquiries, I have created a temporary web page at Google with all the files needed for the configuration, ...

Happy LyX-ing with R!

Prosti tečaji preko spleta

Že kar nekaj časa nazaj je MIT na splet prenesel celo kopico predmetov. Pri velikem številu predmetov so na voljo vsa gradiva in to ZASTONJ! Vse skupaj najdete tukaj.

Ampak to ni vse, ravno sem naletel na seznam univerz z naj prostimi tečaji - klik.

Portal Drobnic@

Portal Drobnic@ že deluje nekaj časa in ni slabo, da ga omenim še tukaj. Skratka vabljeni.

An LSD joke

After a while ..

A teenage boy asks his granny 'Have you seen my pills, they were labelled
LSD?'

Granny: 'Fuck the pills; have you seen the dragons in the kitchen?'

Plače?

Po mailu dobim sledeči link, ki prikazuje plače. Najprej sem rekel, da ne bom pogledal. Seveda se nisem mogel upreti. Kdo vse spada na seznam ne vem. Po pregledu, sem se vprašal kako lahko ima ravnatelj srednje šole večjo plačo kot predsednik republike? Slučajno poznam dotično gimnazijo in mirne volje rečem, da tole enostavno ne more iti skupaj. Sicer ne vem, kaj dela predsednik republike, ker ga itak ni na spregled že nekaj časa - za to dobi 6.482 EUR/mesec. Je čisto vseeno ali je bruto ali neto. Vsekakor ravnatelj srednje šole po mojem ne bi smel imeti večjo plačo kot predsednik republike. Hmm. Zelo visoko je tudi na seznamu ravnatelj osnovne šole. Pa ne da podcenjujem delo šol, ampak kar je preveč je preveč.
