Commit bc6c183 introduced a bunch of discrepancies between what files
look like in the repo and what clang-format says they should look like.
However, there were already a few discrepancies prior to that. Most of
these discrepancies seemed to be unintentional, but a few of them were
load-bearing (e.g., a #include that violated header ordering needing
something to have been #defined by a 'later' #include.)
I opted to take what I hope is a relatively smooth-brained approach: I
reverted the .clang-format change, ran clang-format on the whole repo,
reapplied the .clang-format change, reran clang-format again, and then
reverted the commit that contained the first run. Thus the full effect
of this PR should only be to apply the changed formatting rules to the
repo, and from skimming the results, this seems to be the case.
My work can be checked by applying the short, manual commits, and then
rerunning the command listed in the autogenerated commits (those whose
messages I have prefixed auto:) and seeing if your results agree.
It might be that the other diffs should be fixed at some point but I'm
leaving that aside for now.

@fileoverview Converts ASCII combining marks to UNICODE.
|
||
|
||
Getting started:
|
||
|
||
nroff -mandoc -rLL=72n -rLT=78n -Tutf8 <manpage.1 |
|
||
o/tool/viz/ascii2utf8
|
||
|
||
ASCII Bold:
|
||
|
||
- CHAR BACKSPACE CHAR c ++ "\b" ++ c
|
||
e.g. AABBCCDD 410841 420842 430843 440844
|
||
|
||
ASCII Underlines:
|
||
|
||
- CHAR BACKSPACE LOW LINE c ++ "\b_"
|
||
e.g. A_B_C_D_ 41085F 42085F 43085F 44085F
|
||
|
||
UNICODE Underlines:
|
||
|
||
- COMBINING LOW LINE U+0332 (\xCC\xB1)
|
||
e.g. A̲B̲C̲D̲ (ugly notches) 41CCB2 42CCB2 43CCB2 44CCB2
|
||
|
||
- COMBINING MACRON BELOW U+0331 (\xCC\xB1)
|
||
e.g. A̱ḆC̱Ḏ (too short) 41CCB1 42CCB1 43CCB1 44CCB1
|
||
|
||
- COMBINING DOUBLE MACRON BELOW U+035F (\xCD\x9F)
|
||
e.g. A͟B͟C͟D͟ (too long) 41CD9F 42CD9F 43CD9F 44CD9F
|
||
|
||
- DOUBLE PLUS COMBINING MACRON BELOW 3×U+035F + 1×U+0331
|
||
e.g. A͟B͟C͟Ḏ (too narrow) 41CCB1 42CCB1 43CCB1 44CD9F
|
||
|
||
- DOUBLE PLUS COMBINING MACRON LOW LINE [it's complicated]
|
||
e.g. A͟B͟C͟D̲ (𝑓𝑙𝑎𝑤𝑙𝑒𝑠𝑠) 41CD9F 42CD9F 43CD9F 44CCB2
