2018-11-16libdraw: redo default font construction to be hidpi-safeRuss Cox20-587/+374
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.

Paint first appeared in 9front. The 9front license is reproduced in the related source files - the original repository is located at https://code.9front.org/hg/plan9front.
2018-11-15rio: make 'mk all' explain why it does nothing on non-x11 systemsRuss Cox1-2/+4
Fixes #98.

2018-11-15acme: add 32x32 boxcursorRuss Cox4-2/+71
The only difference from the upscaled 16x16 is a one-pixel adjustment in the offset position, but this at least exercises setcursor2.
2018-11-15INSTALL: set CC9 on macOS to use xcrun clangRuss Cox1-0/+1
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.
2018-11-15devdraw: add Cursor2 support on macOS 10.14 MojaveRuss Cox8-45/+113
This replaces the pixel-art scaling algorithm used for upscaling before. The results were not crisp enough to serve as everyday cursors.
2018-11-15tweak: add support for Cursor2Russ Cox1-30/+78
2018-11-15libdraw: add Cursor2, a 32x32 high-res cursorRuss Cox11-7/+86
Also add setcursor2, esetcursor2, and draw protocol encoding. Calls to the old setcursor, esetcursor create a 32x32 by pixel doubling when needed.
2018-11-15devdraw: rewrite the Cocoa screen using MetalXiao-Yong Jin8-21/+1307
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.
2018-11-14upas/smtp: fix TLS connections (#163)Zach Scott2-0/+49
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.

2018-11-14devdraw: set displaydpi on devdraw x11 attach (#178)Gabriel Díaz1-2/+7
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.

2018-11-139term.app: add $PLAN9/bin to $PATH if not already in $PATH (#144)KADOTA, Kyohei1-0/+4
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"
2018-11-13plumb/basic: avoid wrap around in file:1:2 (#158)Martin Kühl1-2/+2
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.

2018-11-13fontsrv: x11 uses FC_POSTSCRIPT_NAME (#174)Xiao-Yong1-1/+1
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.
2018-11-13acme: avoid division by zero when resizing col (#189)Fazlul Shahriar1-2/+6
To reproduce, create a column with at least two windows and resize acme to have almost zero height.
2018-11-13fontsrv: disable font smoothing on osx (#196)Xiao-Yong2-0/+4
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.
2018-11-139term: fix getpts on FreeBSD 11.2 (#199)Xiao-Yong1-0/+16
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.

2018-10-05fontsrv: copy some fixes from OS X to X11Fazlul Shahriar1-38/+43
* 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) Change-Id: Icdc2b641b8b0c08644569006e91cf613b4d5477f
2018-10-05upas/nfs: correctly quote IMAP LOGIN argumentsCharles Collicutt1-1/+1
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.
2018-10-01grep: update from Plan 9David du Colombier1-3/+3
This change fixes a segfault in grep -e when no argument has been provided. Thanks to Sean Hinchee for reporting this issue. Fixes #186.
2018-09-29libregexp: include stddef.h in lib9.std.hDavid du Colombier1-0/+1
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.
2018-09-19acme: Apply each -/+ only once (#156)Martin Kühl1-3/+3
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.
2018-06-26fontsrv: omit box-drawing characters from line struts on macOSIgor Burago1-1/+1
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.

2018-03-23fontsrv: skip only the surrogate pairsMechiel Lukkien1-1/+1
fontsrv wasn't rendering fontawesome icons, which uses the private use area around 0xf000.
2018-03-23mount: check current osxfuse kext locationMartin Kühl1-0/+2
Current versions of osxfuse ship with multiple versions of its kernel extension (kext) for differend versions of macOS. Running mount(1) on macOS with a current version of osxfuse fails with `don't know how to mount (no fuse)' since it fails to find the kext. Running 9pfuse(4) directly works fine. This change adds a check to mount(1) that determines: 1) which version of macOS we're running on 2) if there is an osxfuse kext available for this version of macOS
