Summer is coming and I've got a couple of posts cooking that may turn out mildly interesting, but — time constraints being what they are — in the meantime there's this.<\/p>\n\n\n\n

Chafa<\/h2>\n\n\n\n

I (judiciously, as one might opine) pulled back from posting about every single feature release, but things have kept plodding along in quiet. ImageMagick is finally going away as per a buried remark from 2020<\/a>, which means no more filling up \/tmp, no more spawning Inkscape to read in SVGs, and so on. There's also lots of convenience and robustness and whatnot. Go read the release notes<\/a>.<\/p>\n\n\n\n

\"\"
Text terminals, ANSI art groups, my dumb pet projects: they just won't.<\/figcaption><\/figure>\n\n\n\n

As for eye candy, I guess the new 16\/8-color mode qualifies. It's the good old \"eight colors, but bold attribute makes foreground bright\" trick, which requires a bit of special handling since the quantization step must apply two different palettes.<\/p>\n\n\n\n

With this working, the road to ANSI<\/a> art<\/a> scene<\/a> Naraka<\/s> nirvana is short: Select code points present in your favorite IBM code page<\/a>, strip newlines (only if your output is 80 columns wide), and convert Chafa's Unicode output to the target code page. You'll get a file worthy of the .ANS extension and perhaps a utility like Ansilove<\/a> (to those who care: There's some mildly NSFW art in their Examples section. Definitely don't look at it. You've been warned).<\/p>\n\n\n\n

Taken together, it goes something like this:<\/p>\n\n\n\n

$ chafa -f symbol -c 16\/8 -s 80 -w 9 --font-ratio 1 --color-space din99d \\\n    --symbols space+solid+half+stipple+ascii they_wont.jpg | tr -d \\\\n | \\\n    iconv -c -f utf8 -t cp437 > they_wont.ans\n$ ansilove -f 80x50 -r they_wont.ans -o top_notch_blog_fodder.png<\/code><\/pre>\n\n\n\n
It's a bit of a screenful, but should get better once I get around to implementing presets.<\/p>\n\n\n\n
Finally, I added a new internal symbol range for Latin scripts. It's got about 350 new symbols to work with on top of the ASCII that was already there. Example anim below; might be a good idea to open this one in a separate tab<\/a>, as browser scaling kind of ruins it.<\/p>\n\n\n\n
\"\"
--fg-only --symbols latin<\/code>. Input from 30000fps<\/a>.<\/figcaption><\/figure>\n\n\n\n
Thanks<\/h2>\n\n\n\n
Apart from the packagers, who are excellent but too numerous to list for fear of leaving anyone out, this time I'd like to thank Lionel Dricot aka Ploum<\/a> for lots of good feedback. He develops a text mode offline-first browser for Gemini<\/a>, Gopher, Spartan and the web called Offpunk<\/a>, and you should check it out.<\/p>\n\n\n\n
One more. When huntr.dev<\/a> came onto my radar for the first time this spring, I admit to being a little bit skeptical. However, they've been a great help, and every interaction I've had with both staff and researchers has been professional, pleasant and highly effective. Big thumbs up. I've more thoughts on this, probably enough for a post of its own. Eventually.<\/p>\n\n\n\n
A propos<\/h2>\n\n\n\n
I came across Aaron A. Reed's project 50 Years of Text Games<\/a> a while back (via Emily Short's blog<\/a>, I suspect), and have been following it with interest. He launched his kickstarter<\/a> this week and is knocking it out of the park. The selection is a tad heavy on story\/IF games (quoth the neckbeard, \"grumble grumble, Empire<\/a>, ZZT<\/a>, grumble\"), but it's really no complaint considering the effort that obviously went into this.<\/p>\n\n\n\n
\"\"<\/figure>\n\n\n\n
Seems low-risk too (the draft articles are already written and available to read<\/a>), but I have a 75% miss rate on projects I've backed, so what do I know. Maybe next year it'll be 60%.<\/p>\n","protected":false},"excerpt":{"rendered":"
