I’ve had occasion to create some installer packages lately, and the topic of assigning a version number to them has rattled around in my head. The version number of an installer package is shown in the Finder’s Get Info windows, and in the preview pane of column view, so it has some usefulness just for telling one installer apart from another. And, importantly, the version number provides a way for Installer to determine whether a package has previously been installed and simply needs to be upgraded.

At first, I was just going to assign the date in YYYYMMDD format as the version, just to “keep things simple” by using:

Then I was rebuilding the packages several times a day, and wanted to distinguish between the builds, so I switched to YYYYMMDD.hhmm.

This seemed ridiculous after a day. Although I could distinguish between builds, the installers I was building weren’t really changing per se. They were the same payload and scripts and resources, just rebuilt by the command line packagemaker tool using The Luggage.

I crowdsourced my question about versioning, and Steve Losh helpfully responded with the idea to use Mercurial tags along with Semantic Versioning.

My package sources are already checked into Mercurial repositories, so this made a good deal of sense. It meant that I’d have to use tags to identify a version number — it would no longer be as automatic as using the current date. However, certain parts of the version string would be automatic, and the only manual part would be tagging revisions in Hg.

I had already bookmarked Semantic Versioning a while back, but had forgotten about it and never done much of anything with it. If I followed the Semantic Versioning standard, I’d create a “semver” tag to set up the repository, and then a new “vX.Y.Z” tag for actual releases thereafter. Steve further suggested the use of the “latest tag distance” and “short node hash” for the Hg revision, and that information is automatically available from Hg.

Semantic Versioning states, “when tagging releases in a version control system, the tag for a version MUST be ’vX.Y.Z’ e.g. ’v3.1.0’.” I felt I would have to strip the “v” from the version tag to use it cleanly as a package version. This results in commands like the following, where I’ve used sed to remove that character:

This is something I can build into makefiles for use with The Luggage, so I’m going to try it out. On first glance, I think it even fits in nicely with the concept of The Luggage. It automates much of the version-assignment process. And, it takes advantage of version control for both repeatable results and peer review.

The Address Book application in Mac OS X Snow Leopard has a new telephone number label for contacts: “iPhone.” (Credit to Jeff Carlson for bringing it to my attention.)

What I find just as interesting as its existence is its order in the list. The “iPhone” label comes before “mobile,” the label I used for all cellular numbers. Is that a subtle dig to put the iPhone above other mobile phones?

It is also the only label that rates a capital letter.

I have no idea how or if this label will survive through Entourage Sync Services and Exchange synchronization. Hm.

Update: I wouldn’t advise using this label right now if you use Sync Services or otherwise sync data elsewhere. I’ve already lost cell numbers in Entourage with Sync Services enabled when I flipped an existing “mobile” number to “iPhone” and back.

Update: I have tested it twice with dummy contacts and could not reproduce the problem that resulted in the number being removed from both Entourage and Address Book. (I believe this is odd because it happened to two of my existing contacts when I flipped them to “iPhone” and back to “mobile.”) However, the “iPhone” number does definitely get removed from Entourage through Sync Services, which means you would lose the number on anything connected to an Exchange account (if Entourage is synchronizing with Exchange). … Such as an iPhone with Exchange ActiveSync.

Apache Solr provides a Web service front end for the Apache Lucene indexing and search engine library. Both Solr and Lucene (upon which Solr depends) are Java-based, which has implications for shared Web hosting.

Drupal is an open source CMS, and I happen to use it on a shared Web hosting provider as of this writing. Drupal is gaining support for Apache Solr through a module that has had a lot of input from Acquia (the “Red Hat” of Drupal).

Dries Buytaert of Acquia has some interesting perspective on search for the Web and CMSes in some recent articles on his site. Specifically, he talks about Acquia Search, a Solr-based search service that is being offered to Drupal sites on the Acquia Network. He discusses the advantages afforded by good search capabilities for both visitors to a Drupal Web site and for site administrators.

I’ve used Acquia Search (in beta), and it has been great. It’s very fast compared to the core Drupal Search module. The ability to perform faceted searches, word stemming, spell checking, and more is all tremendous. (You can see it in action in the search field in the site sidebar, as long as my Acquia Network subscription from the beta lasts.)

But Acquia Search part of a larger service offering — the Acquia Network — which ultimately makes it too expensive for me on my personal sites. It’s priced out of reach for me — more costly for one year than two years of Web hosting, domain registrations, and separate e-mail hosting for my domains are today. I think it’s clear that Acquia is aiming at a different market, and that’s fine.

My idle thought, however, is that search by itself is a compelling feature even for small Web sites like mine. It’s as compelling as hosting files, like HTML or PHP or images, or serving databases, like MySQL and PostgreSQL.

If it’s important as Dries notes in his posts — that the search market is so large and growing, and of such universal importance — then great search is a compelling feature to have for many levels of sites. After serving the files and serving the database, it may be the next big service that a Web hosting provider could offer. And today, Web hosting offers a range of pricing (and service levels) to meet various needs.

I could see advertising that for some monthly fee, a Web host offers 55 GB of storage and 550 GB of monthly data transfer and unlimited MySQL databases — and oh, by the way, some reasonable level of indexing/search with Apache Solr and/or Sphinx or whatever. Although I hate to suggest it, search could even be an optional add-on, as many providers treat dedicated IP addresses or SSL or the like.

There may be an additional win, in that separate servers could be optimized for search to offload that processing from the Web server. It could even be something that a Web host contracts out or partners with another to provide — maybe even with a company like Acquia that’s already set up their infrastructure to scale on Amazon EC2.

Especially if other CMSes, such as WordPress, get Solr integration — as with this WordPress Solr plugin — then the case for Web hosts offering something like Solr search gets convincing.

I wanted to find a way to do syntax highlighting of code snippets on my Drupal blog. I came across the GeSHi Filter module, which lets Drupal sites take advantage of the apparently well-regarded GeSHi Generic Syntax Highlighter library that’s meant for just this purpose.

However, I ran into some roadblocks implementing it on my site. Here’s the short story of what I settled on after some trial and error.

My existing code snippets are in <code> blocks, and the initial GeSHi Filter settings applied badly to them. I made the decision to only use GeSHi on <blockcode> blocks, since I wasn’t using that tag yet and it wouldn’t conflict with the snippets already posted.

I most commonly write Bash/Zsh, Python, and AppleScript snippets on my blog. However, the Bash code I was using as part of my trial and error simply wasn’t highlighting; it was coming through as the default (and boring) plain text — but was at least boxed off from the rest of the blog post.

I thought that GeSHi wasn't correctly discovering that the code was written in UNIX shell syntax. I couldn’t find a way to specify the language for that blockcode tag, until I did some searching on the ’net. To change my blockquotes to choose a certain language — at least for the purposes of this Drupal module, if not for GeSHI in general — I needed to add the “lang=lang” style to the tag. For Bash, I could use “lang=bash,” for Python, “lang=python,” and for AppleScript, “lang=applescript.” That made sense.

However, my code was still not being syntax highlighted. I discovered that the Drupal module came with an initial set of languages enabled. The others were all turned off, but that could be changed in the module settings. Without turning them on, even properly-tagged <blockcode> sections did not get the benefit of syntax highlighting.

I changed the GeSHi Filter options to enable some of the languages that were initially disabled, and then disabled the ones I didn’t anticipate using. This allowed me to add Bash and AppleScript syntax highlighting support, as both had been turned off by default. After that, I saw the results I’d hoped for: a syntax-highlighted code snippet.

It took some work, but now that it’s done, I should be all set.

Oh. My. Gosh. I heard about and installed the Taxonomy Manager module for Drupal 5 — which was a just-completed Google Summer of Code 2007 submission — and it is fantastic. It makes managing taxonomy in Drupal so much more fluid. No, it makes taxonomy management possible.

It’s not perfect, and there are little visual oddities in the version I installed, but Taxonomy Manager is so much better than the normal user interface for taxonomy in Drupal core that I can’t see using anything else now. I’ve been spoiled.

Hearing about stuff like this — even if it’s nearly a throwaway comment by Angie Byron, almost lost in all the other voices on episode 48 — is exactly why I listen to the Lullabot Drupal Podcast. Thank you.

Oh, and sometime, I will look into free tagging. Gotta do that. Love it on del.icio.us.
