df2322d7	2025-02-05T14:41:21	Replace include guards by `#pragma once` We currently have a mix of include headers, pragma once and some missing. pragma once is not standard but is widely supported, and we already use it with no issues, so I'd say it's not a problem. Let's convert all headers to pragma once to avoid the annoying include guards. The public headers are not converted. Signed-off-by: Ran Benita <ran@unusedvar.com>

It did accidentally enable the detection of alphabetic key type for the pair (ß, ẞ) though. However this detection was accidentally removed in 5c7c79970a2800b6248e829464676e1f09c5f43d (v1.7) with an attempt to fix the wrong keysym case mapping. Finally both the lower case mapping and the key type detection were fixed for good when we implemented the complete Unicode simple case mappings and corresponding tests in e83d08ddbc9851944c662c18e86d4eb0eff23e68. However, the upper case mapping `ssharp` → `U1E9E` remained disabled. Indeed, ẞ is a relatively recent addition to Unicode (2008) and had no official recommendation, until recently. So while the lower mapping ẞ→ß exists in Unicode, its converse upper mapping does not. Yet since 2017 the Council for German Orthography (Rat für deutsche Rechtschreibung) recommends[^1] ẞ as the capitalization of ß. Due to its stability policies, the Unicode Character Database (UCD) that we use to generate our keysym case mappings (via ICU) cannot update the simple case mapping of ß. Discussions are currently ongoing in the Unicode mailing list[^2] and CLDR[^3] about how to deal with the new recommended case mapping. However, the discussions are oriented on text-processing and compatibility mappings, while libxkbcommon is on a rather lower level. It seems that the slow adoption of ẞ is partly due to the difficulty to type it. Since ẞ is used only for ALL CAPS casing, the expectation is to type it using CapsLock. While our detection of alphabetic key types works well[^4] for the pair (ß,ẞ), the internal capitalization currently does not work and is fixed by this commit. Added the ß → ẞ upper mapping: - Added an exception in the generation script - Fixed tests - Added documentation of the exceptions in `xkbcommon.h` - Added/updated log entries [^1]: https://www.rechtschreibrat.com/regeln-und-woerterverzeichnis/ [^2]: https://corp.unicode.org/pipermail/unicode/2024-November/011162.html [^3]: https://unicode-org.atlassian.net/browse/CLDR-17624 [^4]: Except libxkbcommon 1.7, see the second paragraph.

Replace include guards by `#pragma once` We currently have a mix of include headers, pragma once and some missing. pragma once is not standard but is widely supported, and we already use it with no issues, so I'd say it's not a problem. Let's convert all headers to pragma once to avoid the annoying include guards. The public headers are *not* converted. Signed-off-by: Ran Benita <ran@unusedvar.com>
