2020-01-14acme: save/restore multiline tags in Dump/LoadRuss Cox1-4/+16
The dump substitutes each \n in a multiline tag with a 0xff byte. Since it is not valid UTF it cannot occur in an ordinary dump file. Old acmes will just read it in as an error rune. Fixes #135. Fixes #153.

2020-01-13acme: fix movetodel for spaces in file namesRuss Cox1-11/+8
2020-01-13acme: allow spaces in window namesRuss Cox2-5/+20
There are many things we could do to make this work. an environment variable to control the character. Another option would be to use U+00A0 (non-breaking space), which renders the same as space. This change avoids changing the separator character and instead assumes that if the left side of the tag already ends in " Del Snarf |" then what comes before that is the file name. Acme already aggressively preserves the "Del Snarf |", so this should work decently well as a stop-gap. We can always try something else later. Fixes #26. Fixes #104. Fixes #329.

Just as look expands a click in /etc/passwd to the full name (provided that file exists), it now expands a click in https://9fans.net/ to the full URL (provided the prefix is http:// or https://). Probably more adjustment is needed.
2019-05-17acme: delete trailing spaces during Put in autoindent modeRuss Cox1-41/+64
Autoident mode is the leading cause of trailing spaces on lines. Remove them during Put to make various picky tools happier. The changes during Put are added as a separate entry to the file history, so that the first Undo after Put restores the spaces.
2019-04-19acme: do not trim spaces during PutRuss Cox1-4/+8
The commit that introduced this was pushed accidentally. It is not a good idea to do this. (It breaks programs that think that a clean window means the body matches the on-disk file.)

2019-02-01acme: drop trailing spaces during Put of auto-indent windowRuss Cox1-3/+38
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.
2018-11-15acme: add 32x32 boxcursorRuss Cox4-2/+71

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.

2017-11-02acme: preserve window position and selection during GetRuss Cox5-18/+103
Before, executing Get in a file rewound the window offset and selection to the start of the file. After this CL, Get preserves the window offset and selection, where preserve is defined as "the same line number and rune offset within the line". So if the window started at line 10 before and the selection was line 13 chars 5-7, then that will still be true after Get, provided the new content is large enough. This should help the common situation of plumbing a compiler error, realizing the window is out of date, clicking Get, and then losing the positioning from the plumb operation.

Thanks to Lorenzo Beretta for noticing.
2017-10-10acme: check file content before declaring file "modified since last read"Russ Cox23-13/+79
Bad remote file systems can change mtime unexpectedly, and then there is the problem that git rebase and similar operations like to change the files and then change them back, modifying the mtimes but not the content. Avoid spurious Put errors on both of those by checking file content. (False positive "modified since last read" make the real ones difficult to notice.)

2014-06-03acme: fix bufread crash due to typing-point scrollingRuss Cox1-0/+4
Acme tracks the most recent typing insertion point and the home and end keys stop there on their way up to the top or down to the bottom of the file. That point should be iq1, and it should be adjusted properly so that it's always between 0 and t->file->b.nc inclusive. (This is all code from an external contributor, years old at this point but new since Plan 9.) Somehow, sometimes iq1 ends up a little beyond b.nc, and when passed to textbacknl it crashes acme in bufread. I can't see how that can happen but if it does, avoid the crash. It's tempting to pull the insertion point code out entirely but this is a little less invasive and should fix things for now. TBR=rsc https://codereview.appspot.com/107730043
2014-06-03acme: increase timer resolution to 10msRuss Cox1-1/+1
We ran for a long time with 10ms kernel resolution, so 10ms user space resolution here should be fine. Some systems actually provide 1ms sleeps, which makes this polling use a bit more cpu than we'd like. Since the timers are for user-visible things, 10ms should still be far from noticeable. Reduces acme's cpu usage on Macs when plumber is missing (and plumbproc is sleeping waiting for it to appear). LGTM=aram, r R=r, aram https://codereview.appspot.com/99570043

This breaks ^C in win windows, as expected. People use ^C, win expects and handles ^C, so I don't think we can just take it away. I've noticed that it is broken but assumed my ssh was screwed up. If you want to make WindowsKey+C,X,V do the operations, by analogy with command+C,X,V on Mac, that's fine with me. ««« original CL description acme: copy/cut/paste with ctl+c,x,v LGTM=rsc R=rsc CC=plan9port.codebot https://codereview.appspot.com/69070045 »»» TBR=rsc CC=burns.ethan, r https://codereview.appspot.com/96410045

2014-04-30acme: add log file in acme root directoryRuss Cox11-6/+236
Reading /mnt/acme/log reports a log of window create, put, and delete events, as they happen. It blocks until the next event is available. Example log output: 8 new /Users/rsc/foo.go 8 put /Users/rsc/foo.go 8 del /Users/rsc/foo.go This lets acme-aware programs react to file writes, for example compiling code, running a test, or updating an import block.

2014-04-19acme: use buffered i/o to write fileRuss Cox1-1/+16
Bakul Shah has observed corrupted files being written when acme writes over osxfuse to sshfs to a remote file system. In one example we examined, acme is writing an 0xf03-byte file in two system calls, first an 0x806-byte write and then a 0x6fd-byte write. (0x806 is BUFSIZE/sizeof(Rune); this file has no multibyte UTF-8.) What actually ends up happening is that an 0x806-byte file is written: 0x000-0x6fd contains what should be 0x806-0xf03 0x6fd-0x7fa contains zeros 0x7fa-0x806 contains what should be 0x7fa-0x806 (correct!) The theory is that fuse or sshfs or perhaps the remote file server is mishandling the unaligned writes. acme does not seem to be at fault. Using bio here will make the writes align to 8K boundaries, avoiding the bugs in whatever underlying piece is broken. TBR=r https://codereview.appspot.com/89550043

Mail services (such as Google Mail) will often have directories with names that contain spaces. Acme does not support spaces in window names.
