XBM ("X BitMap") files are an early precursor to XPM ("X PixMap") files,
which are currently supported on GitHub (albeit with a misleading name).
Didn't we discuss copyleft licenses not being an issue for sample files not so long ago? (I can't find the issue/PR again :-/) |

Aaaah, man. This is a PITA for me. I need to relearn Rails migrations if we do this. If I don't put in a migration, we end up with the same problems we had with the Pelr6 -> Perl 6 change and the DB and search gods frown upon me.

Well, erh, should we then start thoroughly reviewing the hell out of every single grammar-name to make any other potential future change happen in one migration? 😅
I didn't want to rename the entry, as I am conscious of how much of a pain it is database-wise. 😞 Unfortunately, I can't change fact. :( That's a fact.

If the KiCad incident last year proved anything, it's that inaccuracies in language.yml are better dealt with much sooner than a hell of a lot later. 😥

W3C is fine. I don't see a copy of it in this PR though. |
|
Oh. No, I didn't include a copy as I was asking about licenses for sample files.
So I'm guessing @pchaigno is right? |
|
@Alhadis if we're relying on a license to distribute sample material from this repo, we need to comply with the license we're relying on. The W3C license requires keeping a copy of the license. I recall this coming up before regarding samples: #3650 (comment) |
Converted from a 32×32-sized icon of an SVG version of the Public Domain symbol, which was sourced from Wikipedia.

Actually, never mind. I converted one myself (using a 32×32-sized 2-colour version of the Public Domain symbol):

@Alhadis 🆒. Side note: slightly better, or additional, link in your comment above would be to https://commons.wikimedia.org/wiki/File:Cc-public_domain_mark_white.svg (the page about the file, which on Wikimedia Commons always includes copyright/license/public domain info). It isn't a given that an image about the public domain will itself be public domain 😬 though thankfully this one is. |

This PR introduces support for a text-based bitmap image format called X BitMap. (Not to be confused with the currently-supported and superficially similar format, X PixMap.
Description
This PR also adjusts XPM's
languages.ymlentry so it's technically correct and uses its longer, human-readable name (since that's how those images get referred to everywhere else).Both formats use C syntax, so I've lumped them under the
Cgroup whilst leaving their language-types todata(since that's ultimately what they are).In-the-wild usage
~364,280 results for
xbmfiles, none of them shared with a recognised language. From what I've gone through, they're all XBM data.Sample files
Update:
Replaced the sample images with a manually-converted one that's free from licensing complications.
Both of thexbmsamples I've added were hocked fromw3c/libwww:image.xbmdoc.xbmLicensing-wise, they're released under the W3C Software Notice and License, which is new to me. Wikipedia's page for the W3C's license states that it's acceptably permissive and non-copyleft, though it mentions GPIL compatibility.The full license text can be found here. Should we summon the wisdom of our venerable LawGuruGuy™, @mlinksva? Even though this license looks okay, I dare not tread the swampy waters of "Legal-Looking Stuff That Will Actually Get You Life-Jailed If You Read It Wrong". Hereafter known asLLSTWAGYLJIYRIW, my new favourite Perl motto.
