2013-02-22Stop using 'short' for line and allocation sizesHEADmasterLinus Torvalds2-8/+8
Yes, yes, it probably made sense 30 years ago as a way to save a tiny amount of memory, but especially when interspersed in structures that have pointers (aligned to 64 bits these days), it's not even saving memory today. And it makes us fail in nasty ways when looking at files with long lines. So just make them 'int'. And if you have a line that is longer than 2GB, you only have yourself to blame. I no longer care. In case anybody care, the "test-case" for this was a lovely UDDF file with a binary divecomputer dump encoded as an XML element. Resulting in a lovely 41kB single line. Not what poor micro-emacs was designed for, I'm afraid. I really should just learn another editor, rather than continue to polish this turd.

2013-02-22Avoid memory access errors if llength() overflowsLinus Torvalds1-1/+1
llength() is currently a 'short' which can overflow and result in signed numbers if line lengths are larger than 32k. We'll fix the overflow separately, but before we do that, just use a signed int to hold the value so that we don't overrun memory allocations when we converted that negative number to a large positive unsigned integer.

2012-09-24Fix the unicode character limit (0 .. 0x10ffff)Linus Torvalds2-1/+3
For some reason I had limited things to 0xffff, it really should be 0x10ffff. We don't actually support a full 32-bit unicode model anyway, since we use the high bits for the control/meta/^X/special bits, but there was no reason to limit things to 16 bits when we had 28 bits available. And the real limit for real Unicode characters is 0x10ffff. Add a silly example character past the 16-bit range to the UTF8 demo file: 'SMILING FACE WITH HALO' (U+1F607) from the 'emoticons' block.

2012-07-15Fix 'getccol()' and 'getgoal()' functions for multibyte UTF-8 charactersLinus Torvalds2-8/+22
These functions convert the byte offset into the column number (getccol()) and vice versa (getgoal()). Getting this right means that moving up and down the text gets us the right columns, rather than moving randomly left and right when you move up and down. We also won't end up in the middle of a utf-8 character, because we're not just moving into some random byte offset, we're moving into a proper column. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2012-07-11Fix vtputc() and simplify show_line by using it againLinus Torvalds1-24/+10
This re-introduces vtputc() as the way to show characters, which reinstates the control character handing, and simplifies show_line() in the process. vtputc now takes an "int" that is either a unicode character or a signed char (so negative values in the range [-1, -128] are considered to be the same as [128, 255]). This allows us to use it regardless of what the source of data is. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2012-07-11Start doing character removal properlyLinus Torvalds6-16/+48
This makes actual basic editing work. Including things like justify-paragraph etc, so lines get justified by number of UTF8 characters rather than bytes. There are probably tons of broken stuff left, but this actually seems to get the basics working right. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2012-07-11Start actually inserting full utf8 sequencesLinus Torvalds2-2/+21
This makes it possible to cut-and-paste the UTF8 testfile into a new buffer, and the end result looks correct. NOTE! We still do various things wrong while editing. For example, while the cursor movements were fixed, simple things like deleting a character still work on single bytes, rather than utf8 characters. So while this is getting much closer to actually editing UTF-8 data, it's not there yet. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2012-07-11Make 'show_line()' do proper TAB handlingLinus Torvalds1-4/+17
The TAB handling got broken by commit cee00b0efb86 ("Show UTF-8 input as UTF-8 output") when it stopped doing things one byte at a time. I'm sure the other special character cases are broken too. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2012-07-10Expand keycode to 'int' from 'short'Linus Torvalds1-5/+5
This uses the four high bits for the meta and control key sequences. This means that we will be limiting our Unicode space to 28 bits, but that's more than we really need. It *would* be nicer if we just used the sign bit to mark "we have meta character information") but that would require bigger changes. And we really don't need to worry about 30-bit unicode. Small steps, remember. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2012-07-10character input: make sure we have enough bytes for a full utf8 characterLinus Torvalds1-2/+19
.. but we do have that 0.1s delay, so if somebody feeds us non-utf8 sequences, we won't delay forever. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2012-07-10utf8: make sure to honor the array length properlyLinus Torvalds1-2/+2

2012-07-10Make kbd macro save area use 'int' instead of shortLinus Torvalds2-6/+6
I'm starting to expand the input value from 'short' (with flags in the upper eight bytes) to 'int' (with negative values having flags). Small baby steps. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2012-07-10Use utf8 helper functions for keyboard inputLinus Torvalds1-49/+17
ttgetc() used some homebrew utf8 to unicode translation, limited to just the normal latin1 characters. Use the utf8 helper functions to get it right for the more complex cases. NOTE! We don't actually handle characters > 0xff right anyway. And we still end up doing Latin1 in the buffers on input. One small step at a time. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2012-07-10Make cursor movement (largely) understand UTF-8 character boundariesLinus Torvalds3-11/+31
Ok, so it may do odd things if it's not truly utf-8, and when moving up and down lines that have utf-8 the cursor moves oddly (because the byte offset within the line stays constant, rather than the character offset), but with this you can actually open the UTF8 example file and move around it, and at least some of the movement makes sense.

Let's just plan on being fully utf8 some day. We're not there yet, and maybe we'll never be, but having the halfway mode is not useful either. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2012-07-10Show UTF-8 input as UTF-8 outputLinus Torvalds1-3/+59
.. by doing the stupid "convert to unicode value and back" model. This actually populates the 'struct video' array with the unicode values, so UTF8 input actually shows correctly. In particular, the nice test-file (UTF-8-demo.txt) shows up not as garbage, but as the UTF-8 it is. HOWEVER! Since the *editing* doesn't know about UTF-8, and considers it just a stream of bytes, the end result is not actually a usable utf-8 editor. So don't get too excited yet: this is just a partial step to "actually edit utf8 data" NOTE NOTE NOTE! If the character buffer contains Latin1, we will transform that Latin1 to unicode, and then output it as UTF8. And we will edit it correctly as the character-by-character data. Also, we still do the "UTF8 to Latin1" translation on *input*, so with this commit we can actually continue to *edit* Latin1 text. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2012-07-10Make the 'struct video' contain an array of unicode characters rather than bytesLinus Torvalds2-37/+40
This is disgusting. And quite frankly, it's debatable whether this will ever work. The "line" structure is still just an array of characters, so that has to work with utf-8. But the 'struct video' thing is what represents the actual screen rectangle, and is fixed-size by the size of the screen. So making it contain actual 32-bit unicode characters *may* make sense. Right now we translate things the same way we always used to, though, so utf-8 in 'struct line' will not be translated to the proper unicode array, but to the bytes of the utf-8 representation. So this really doesn't improve anything per se yet, just expands the memory use of the video array. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2011-08-25spawn.c: do the "keyboard open/close" around shell invocationsLinus Torvalds1-0/+6
I'm not 100% sure we really should even be doing this whole "keyboard" open/close for termcap, but even if the right thing to do ends up being to just do everything in the TTopen/TTclose (and make TTkopen/TTkclose no-ops), it does seem to be the right thing to do.

2011-08-25file.c: remove crazy keyboard open/close callsLinus Torvalds1-8/+0
It seems to have something to do with some old DOS mode, and not having keyboard translation on ("Insert floppy A:" questions while opening files? Whatever). But this is while doing normal file opens, and it is just insane to open/close a tty across a file open. The possible tty init/exit sequence would mess up some of the file read/write messages.

2011-08-25Force a screen re-draw after tcap 'ti' on terminal openLinus Torvalds1-0/+7
The 'tcapkopen()' function re-initializes the terminal with the 'ti' sequence, which for most sane termcap entries is just empty. But for 'xterm', that seems to actually be a real control sequence (clear and reset?), and we'd better tell display.c that the screen is now garbage and needs to be re-drawn. Also, make tcapkclose() match the 'ti' (terminal init) with a 'te' (terminal exit). Maybe we should just stop playing games with ti/te, but this at least improves the situation a bit.

2008-06-07Turn ESC+'[' into a CSI characterLinus Torvalds2-34/+58
This avoids the annoying behavior where we're on the command line, waiting for an ESC, and any control character sequence ends up finishing the command line and eating the first ESC. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2006-11-19Clean up various compile warningsLinus Torvalds17-35/+41
Most of them were harmless: gcc not being smart enough to realize that an uninitialized variable was never used if it wasn't initialized etc. Some of them were name clashes ("crypt()" is a standard library function, so rename it to "myencrypt()") etc. Signed-off-by: Linus Torvalds <torvalds@osdl.org>

2005-11-16Make "sparse" check target do a global sparseLinus Torvalds1-1/+1
Instead of iterating over all the source files, just check them all together since it works these days, and could potentially find cross-file issues.
2005-10-10Add a true UTF-8 demonstration fileLinus Torvalds1-0/+212
We obviously don't handle it, but it's a wonderful example if we ever do. Demo by Markus Kuhn from http://www.cl.cam.ac.uk/~mgk25/ucs/examples/UTF-8-demo.txt Signed-off-by: Linus Torvalds <torvalds@osdl.org>
2005-10-02Add support for a "utf-8" modeLinus Torvalds4-5/+103
NOTE! MicroEmacs is very much a byte-based editor, and the new utf-8 support is purely an issue of terminal input and output. The file contents themselves are in the 8-bit space. In that space, Unicode is the same as Latin1. The new mode is called "utf-8", and is enabled automatically by the new emacs.rc when $LANG contains the substring "UTF-8". I'm sure people would like to some day also edit real UTF-8 contents, rather than just edit old 8-bit Latin1 contents in a UTF-8 terminal. However, that's an independent (and much bigger and thornier) issue. Signed-off-by: Linus Torvalds <torvalds@osdl.org>
2005-10-01[PATCH] Fix use of mktemp() in uemacsHorst von Brand1-1/+1

2005-10-01Handle 8-bit characters better in displayLinus Torvalds2-15/+36
This code still assumes a latin1 kind of "one byte, one character" setup. UTF-8 input/output (even if the data is encoded in latin-1) is a separate issue.
2005-10-01Make sources mostly sparse-cleanLinus Torvalds12-37/+9
Mainly an issue of taking care of a few remaining K&R function declarations.
2005-10-01Fix more compiler warningsLinus Torvalds11-63/+76
Better initializers, and more proper function types.
2005-10-01Fix ugly "definitions in header file" crudLinus Torvalds11-193/+174
Move various initializations into new "globals.c" file. Also mark some variables static, and fix up some trivial compiler and sparse warnings.
2005-10-01Avoid various name clashes with curses and termcap headersLinus Torvalds12-56/+47
This allows us to include the proper headers, instead of declaring things (badly) by hand.

Still tons of warnings with "-Wall", but now it's actually getting closer. It even compiles again.

Oh, and change the -O4 to a saner -O2 while at it
2005-09-30More ANSI'ficationLinus Torvalds3-60/+62
Next up: enabling "-Wall" in the makefile. Not because it's ready, but because it gets easier to track where we are in the process..

2005-09-30More ANSI-fication of the sourcesLinus Torvalds4-68/+82
Ugh. Some of this is ugly. We should really include <curses.h> etc, but there are too many name clashes for that right now.

Hey, it's already compiling cleaner. Getting proper function declarations will be a bitch, though.
2005-09-30Very optimistically add a "sparse" makefile target.Linus Torvalds1-0/+6
Since sparse really wants clean ANSI C, we're not even _remotely_ close to being sparse-clean. But maybe some day...

make sure to include <errno.h>, and allow for the fact that newer gcc's don't allow function declarations in function scope (don't ask me why, but there you have it..)
2005-05-31Initial import of em-4.0.15-ltLinus Torvalds50-0/+24188
This is a slightly updated version of uemacs-PK (PK is Pekka Kutvonen) which was used at Helsinki University a long time ago. My fingers cannot be retrained.
