Auto-indent mode leaves trailing spaces on blank lines
as you type past them, so silently elide them from the
window content as it gets written back to disk.
Another option would be to remove them from the
window entirely during Put, but they're actually nice
to have while editing, and to date Put has never
modified the window content.

My MacBook Pro has hw.ncpu=12, so set NPROC=12.
Speeds up INSTALL dramatically.
Should probably add similar code to other OSes.
Also silence rio warning from earlier commit.

If $font is not set, the default font is constructed from
font data linked into every libdraw binary. That process
was different from the usual openfont code, and so it was
not hidpi-aware, resulting in very tiny fonts out of the box
on hidpi systems, until users set $font.
Fix this by using openfont to construct the default font,
by recognizing the name *default* when looking for
font and subfont file contents. Then all the hidpi scaling
applies automatically.
As a side effect, the concept of a 'default subfont' is gone,
as are display->defaultsubfont, getdefont, and memgetdefont.

The only difference from the upscaled 16x16
is a one-pixel adjustment in the offset position,
but this at least exercises setcursor2.

Using plain 'clang' does not work well for the new devdraw on macOS 10.14.
But 'xcrun --sdk macosx clang' does work, for reasons no one understands.
Hopefully this will be OK on all macOS systems.
|

This replaces the pixel-art scaling algorithm used for upscaling before.
The results were not crisp enough to serve as everyday cursors.
|
|
|
|
Also add setcursor2, esetcursor2, and draw protocol encoding.
Calls to the old setcursor, esetcursor create a 32x32 by
pixel doubling when needed.

Add a new macOS cocoa screen, cocoa-screen-metal.m.
Rewrite the macOS cocoa drawing code to use the builtin runloop,
and use Metal to push pixels with CAMetalLayer.
Remove all of the deprecated code, and simplify some of the logic.
Modify mkwsysrules.sh such that the new code is used only when
the system version is equal or higher than 10.14.
Allow touch events to simulate mouse clicks:
three finger tap for the middle mouse button;
four finger tap for the 2-1 chord.
Support Tresize.
Scale 16x16 Cursor up to 32x32 with an EPX algorithm.
Support macOS input sources including the basic dead keys and the
advanced CJK input methods.
Increase the communication buffers in cocoa-srv.c to allow more
input, especially for long sentences prepared by the macOS input
souces.

Both `upas/nfs` and `upas/smtp` call the currently broken `tlsClient()`
from libsec. This commit copies a fix from upas/nfs into upas/smtp.
In `imapdial()`, upas/nfs replaces a process call for tlsClient with
`stunnel3` when not on Plan 9. upas/smtp calls tlsClient directly
as a function, so imapdial was copied into mxdial.c as `smtpdial()`,
and tlsClient+dial replaced with a call to smtpdial.

See https://plan9port-review.googlesource.com/c/plan9/+/1470
for discussion of the approach, especially Michael Stapleberg's comment:
Note that chromium, firefox and others have tried this and then switched to using the Xft.dpi X resource, see e.g. https://code.google.com/p/chromium/codesearch#chromium/src/chrome/browser/ui/libgtk2ui/gtk2_ui.cc and especially http://sources.debian.net/src/gnome-settings-daemon/3.18.2-1/plugins/xsettings/gsd-xsettings-manager.c/?hl=824#L80 for some anecdata about why this approach doesn’t work out.
The Xft.dpi resource is being set accurately by desktop environments (GNOME, KDE, …) and can easily be changed by users of niche window managers by editing ~/.Xresources.
I suggest we check only Xft.dpi, without considering the DPI environment variable or the monitor width/height.

9term set $PLAN9 if PLAN9 is not set. But $PATH is not set.
As a result, 9term exits with "exec devdraw: No such file or directory"

Fixes #122, #140.
As reported in #122, `file:1:1` moves to the end of the file,
and `file:1:2` fails with “address out of range”.
I’ll use file:2:3 as an example so we can tell the line and column number apart.
What’s happening is this:
plumb/basic matches `2:3` using twocolonaddr (from plumb/fileaddr),
then sets addr to `2-#1+#3`
(the 1 is constant and was introduced because column numbers are 1-based).
Acme interprets this in three steps:
1. find the range (q0, q1) that contains line 2
2. create the range (q2, q2) where q2 = q0 - 1
3. create the range (q3, q3) where q3 = q2 + 3
The second step has a branch where if q0 == 0 and 1 > 0
(remember that 1 is constant and comes form plumb/basic),
q0 is set to the end of the file.
This makes addressing things at the end of the file easier.
The problem then is that if we select line 1,
which starts at the beginning of the file,
q0 is always 0 and the branch in step 2) will always be used.
`1:1` is interpreted as `1-#1+#1` which starts at 0, wraps around to the end of the file, then moves 1 character backwards and then forwards again, ending at the end of the file.
`1:2` is interpretes as `1-#1+#2` which starts at 0, wraps around to the end od the file, then moves 1 character backwards and tries moving 2 characters forwards beyond the end of the file, resulting in the out of range error.
In #140 @rsc proposed transforming `:X:Y` into `:X-#0+#Y-#1` instead since that
avoids wrapping around by not moving backwards at first.
This change modifies `plumb/basic` to do that.

This makes fontsrv use the PostScript font names on X11.
The PostScript font names contains only alphanumeric and
hyphens. This allows us to use the Font command in acme.
It also matches the font names used by fontsrv on macOS,
which has been using PostScript font names.
|
|
To reproduce, create a column with at least two windows and resize
acme to have almost zero height.

macOS Mojave version 10.14 starts to disable font smoothing.
We disable font smoothing for OSX_VERSION >= 101400 to match the
system default font rendering.
It also makes the font rendering on macOS similar to that on X11.

Opening /dev/ptyXX files fails on recent
FreeBSD versions.
Following the same fix being applied to
Linux, OpenBSD, and Darwin, we use openpty
to open a pseudoterminal in openpts.

* Avoid allocating empty images by adding 1 to width/height. This was
crashing fontsrv. The total width of the subfont image can be zero
even if the characters are present in the font. For example, all the
characters in x0300.bit (part of "Combining Diacritical Marks" Unicode
block) have zero width.
* Make sure U+0000 is always present in the font, otherwise libdraw
complains with: "stringwidth: bad character set for rune 0x0000 in ..."
* Use the same fallback glyph (pjw face) as OS X. This also fixes a bug
where advance was set to the total width of subfont instead of the
character.
Update #125 (most likely fixes the crash if in X11)

According to RFC 3501 the arguments to the LOGIN command should be
quoted strings (or length prefixed string literals). Without quoting,
authentication to some IMAP servers (e.g. Dovecot) will fail.

Commit 2d82ef9d98 added ptrdiff_t in regcomp.c.
However, this change broke the build of the Unix
package because ptrdiff_t is defined in stddef.h.

When plumbing an address like `3-`, Acme selects line 1,
and similarly `3+` selects line 5.
The same problem can be observed for character addresses (`#123+`)
but _not_ for ones like `+`, `.+` or `/foo/+`:
The problem only occurs when a number is followed by a direction (`-`/`+`).
Following along with the example `3-` through `address` (in addr.c):
We read `3` into `c` and match the `case` on line 239.
The `while` loop on line 242ff reads additional digits into `c`
and puts the first non-digit back by decrementing the index `q`.
Then we find the range for line 3 on line 251 and continue.
On the next iteration, we set `prevc` to the last `c`,
but since that part read ahead _into `c`_,
`c` is currently the _next_ character we will read, `-`,
and now `prevc` is too.
Then in the case block (line 210) the condition on line 211 holds
and Acme believes that it has read two `-` in sequence
and modifies the range to account for the “first” `-`.
The “second” `-` gets applied after the loop is done, on line 292.
So the general problem is:
While reading numbers, Acme reads the next character after the number into `c`.
It decrements the counter to ensure it will read it again on the next iteration,
but it still uses it to update `prevc`.
This change solves the problem by reading digits into `nc` instead.
This variable is used to similar effect in the block for directions (line 212)
and fills the role of “local `c` that we can safely use to read ahead” nicely.

For some fonts, using box-drawing characters in the representative
text for computing the line height results in it being uncomfortably
high. Replace them with accented capitals and tall lower-case letters
which lead to a more conservative increase in the line height.
Fixes #162.
