I have been working steadily on the BlogPoster app, both tightening up the current "production" version and slowly coding the new "modular" version based on Ruby blocks.

Over the weekend I coded up a few blocks in what I hope will be a very atomized app in which all of the blocks do just about one thing and can be called upon in various combinations for different tasks.

Today I worked on the regexes for creating filenames based on post title. The hardest part is dealing with strange characters and website <title> text that contains lots of linefeeds. (Confession: This site did the same until I fixed it. Please don't put linefeeds in your <title>.)

I got rid of the extra linefeeds, but I was ending up with occasional doubled underscores (my go-to replacement character for the space between words). I came up (i.e. Googled and stole) the regex for "match two or more of this character," which in this case is __+, and I was off to the races. I also figured out that in HTML titles with extra lines, I was inadvertently adding an underscore to the beginning of a string, and I used ^_ to find that and kill it out. Regex is fun and profitable.

Hopefully I'll get back to working on the "new" version. I'm coding it slowly and deliberately because I don't want it to be a mess. Next version will be more object-oriented (i.e. will use classes) if I can figure that out. First we'll see how this version turns out,

One thing that bothers me about Twitter is that the 'like' symbol is a ❤ when it should be a 👍. I think a heart means "love," and a thumbs-up means "like." A heart is often too strong for "like," especially in the kind of things that come up on Twitter.

I'd even be open to "like" and "love" with 👍 and ❤, respectively.

I tried this, and it works: How to set file permissions from within Vim | Stack Overflow.

An example. In Vim's command mode:

:call setfperm("foo.txt","rw-r--r--")

It's probably easier to just do this in the Bash shell, but it can be done from within Vi/Vim.

In Bash (to make the files rw-r--r--):

chmod 644 foo.txt

I usually do all the .txt files in the directory (because I generally want text files to be 644, which is rw-r--r--):

chmod 644 *.txt
