2019-10-04vi: Scroll unmodified lines using escape codesJarno Mäkipää
Scroll visual buffer up and down using standard escapes when content has not changed, instead of redrawing every keypress. Sidescroll now moves all the lines instead of only cursor one. Side scrolling long lines unfortunately causes redraw to whole screen. -Jarno
2019-09-23Call ftpget from wgetDenys Nykula
Branch wget to xexec ftpget given an ftp url. Rename the output flag -O like in other wgets. Add mock wget --no-check-certificate to satisfy pkgsrc. Ifdef the version output in wget because the nonexistent constant fails single builds and mkroot.
2019-09-22vi: Added yankJarno Mäkipää
Added: yank and push Rewrote: delete operations Minor cleanups: Rewrote delete operations to use one delete function instead of having separate behavior here and there. Now delete and yank both always move cursor and then clip the whole cursor area into yank register. For example x is just ld or jd depeding are we right edge or not, and dd is jd with some special flags etc. Now only default yank register is implemented, but implemeting yank register list should be trivial since cmd execution already passes register char.
2019-09-19vi: changes to buffer drawingJarno Mäkipää
Replaced: draw_str_until with lib/crunch_str() where possible Removed: Unused char draw functions. Implemented: crunch_nstr() which is crunch_str with additional check for byte length, this can be used to draw substrings or non null terminated strings. (This can be moved to lib/ if its useful for others) Reimplemented: Buffer drawing without line wrapping. Now too long lines are drawn with @ in end. And cursor line scrolls left and right when hitting right margin point. This will simplify buffer handling alot. Linewrapping can be reimplemented later if needed but will add complexity Implemented: set list and set nolist ex commands, set list will show escape codes such as tabs Fix: Bug on splitting 2 lines, split was 1 byte off.
2019-09-09vi: added support for tabsJarno Mäkipää
Add: tabs, follows tabstop variable currently hardcoded to 8. Should be adjustable with :set tabstop N according to man page fix: search, issue with searching substring that is more left than cursor position on following lines.

2019-09-07host: cope with large DNS responses.Elliott Hughes
DNS responses were limited to 512 bytes back when they were UDP only, but if you have a TCP connection you can get up to 64KiB. Also use the existing constant for the size of rrname. Also update the help text. Also consistently use `sizeof(T)` rather than `sizeof T`. Also use consistently use `ARRAY_LEN`. Fixes #56. Test: `toybox host value.testing.express`
2019-09-07vi: small fixes.Elliott Hughes
I really needed to be able to edit a file on the device, and this was the nearest thing handy, and it turns out to be more or less usable for basic editing, so... Support cursor keys. Support :q (since there's currently no record of whether the file's modified or not, :q is the same as :q!). Add 'A' to insert at end of line. Add 'n' to find next after '/'. Fix backspace all the way to get out of ex command mode. Fix escape sequences to not hard-code assumptions about the terminal's default background and foreground colors. Fix 'spesial' typo for 'special', and remove explicit array sizes.
2019-08-29diff and patch: support special characters in filenames with quoting as well ↵William Haddon
as unusual timestamp formats After further research and testing, I've produced a patch which handles all filenames with special characters by copying the GNU quoting behavior, and also treats anything following a tab as a timestamp. This increases both ability to handle possible filenames and ability to apply patches found in the field. In diff, quote and escape filenames according to the following rules. * Surround the filename with quotes if it contains a byte less than 0x20, a byte greater than or equal to 0x80, space, backslash, or quote. * Replace alert, backspace, form feed, newline, carriage return, tab, vertical tab, backslash, and quote with \a, \b, \f, \n, \r, \t, \v, \\, and \", respectively. * Replace other bytes less than 0x20 or greater than or equal to 0x80 with a backslash followed by the three octal digits representing the value of the byte. * Treat valid UTF-8 characters involving sequences of bytes greater than or equal to 0x80 the same as other sequences of such bytes. In patch, process quoted and escaped filenames according to the following rules. * If the filename does not begin with a quote, do not modify the filename. * Remove quotes surrounding the filename. * In quoted filenames, replace \a, \b, \f, \n, \r, \t, \v, \\, and \" with alert, backspace, form feed, newline, carriage return, tab, vertical tab, backslash, and quote, respectively. * In quoted filenames, replace a backslash followed by octal digits with the byte with that value in octal. Also, in patch, treat anything on a +++ or --- line following a tab character after the beginning of the filename as a timestamp, rather than part of the filename.
2019-08-29Fix sh handling nested if/else/elif statements alaRob Landley
if true; then if false; then echo one; elif echo two; then echo three; else echo four; fi; fi
2019-08-23man: fix help, align -k output, and fix double close.Elliott Hughes
The "info" pages are something very different from the "intro" pages :-) do_lines already closes the fd. Also improve the error message for `man`.
2019-08-18Next round of shell plumbing.Rob Landley
You can now run: echo hello; if true; then echo hello; fi; while true; do echo hello; done It's got the start of for loops but needs environment variable resolver to do much with them.
2019-08-15dd: fix skip= with short reads.Elliott Hughes
Subtract the amount we actually read, not what we asked for.
2019-08-09lsof: simplify octal mode display.Elliott Hughes
Since this masks, it doesn't actually have the same bug as e5942a8c90c2f52550496fdf08efddb564d8e5a3, but we may as well fix the other example of that questionable idiom while we're thinking about it...
2019-08-09Split out run_function() and free_function(), add start of _TOYSH_LOCALSRob Landley
marshalling for vforked subshells, fix rc returned from run_pipeline for variable assignment. (Well, sort of: X=$(false) still needs rc = 1.)
2019-08-04Make "if true; then echo hello; fi" work. More work on redirection.Rob Landley
2019-08-02Next round of infrastructure. Start of redirect logic and runtime flow control.Rob Landley
2019-07-31man: switch to xregcomp.Elliott Hughes
All regcomp callers are now going through xregcomp.
2019-07-24crontab: switch to getline().Elliott Hughes
2019-07-22Next round of plumbing evolution. Left in the todo and debug code this time.Rob Landley
2019-07-16ip.c route change support for extended attributes.Mike Bennett
This fixes the extended attribute settings for the ip route change command; extended attributes are collected in a separate buffer and added to the RTM message in a specific RTA_METRICS attribute. Only added setter support for the RTAX_MTU (per-route MTU), as that was the only option currently parsed. Also added support for displaying extended attributes, even those not currently settable.
2019-07-12diff: implement --strip-trailing-cr.Elliott Hughes
Used by some ART tests and also some LLVM tests. (The motivating example is the latter, but I noticed the former when looking for other users.) Bug: http://b/137298656
2019-07-12pidof: fix default behavior, add -x.Elliott Hughes
Before this patch, we're effectively doing `pidof -x` all the time. This patch changes names_to_pid() to allow us to say whether or not we want to include scripts, and adjusts the callers appropriately. Also add tests for `pidof` versus `pidof -x` which pass after this patch, without regressing the existing killall tests.
2019-07-11Next sh checkpoint. Not remotely load bearing yet.Rob Landley
2019-07-11bind/connect cleanup.Elliott Hughes
Rename the existing xbind/xconnect to xbindany/xconnectany, to make room for new xbind/xconnect that are more like 'x' versions of the regular bind and connect. Move explicit bind/connect callers over to xbind/xconnect. Of the affected commands, only netcat is actually used by Android. It was the most recent patch to netcat that made the lack of a more traditional xbind/xconnect apparent.
2019-07-10dd: iflags, oflags, fix ^C, fix the fundamental loop.Elliott Hughes
Investigating why the toybox tar tests fail on Android with toybox dd, I realized I was rewriting a part of dd I'd rewritten before! This is a re-send of my 2019-02-22 patch, rebased against the current ToT... This patch was originally motivated because after suggesting to the author of https://stackoverflow.com/questions/17157820/access-vdsolinux/54797221#54797221 that he could tell dd to work in bytes rather than blocks, I realized that our dd doesn't actually support that. But the rewrite of the main loop is necessary to fix the incorrect output from the dd calls in the tar test. Without this patch, `yes | dd bs=65536 count=1 > fweep` basically gives random output, based on how many bytes the pipe feels like giving you in your first read. (As far as I know, dd *without* bs= was fine, but I can't guarantee that that's true, just that I haven't seen it fail.) Also switch to TAGGED_ARRAY and comma_* for conv rather than add two more copies of an undesired idiom. It turned out -- contrary to the belief of cp(1) -- that comma_scan isn't suitable for this because of its magic handling of "no" prefixes. (It's actually harmless in cp because none of the --preserve options begin with "no", but some dd options do.) To this end, comma_remove is a less-magic comma_scan. I've also changed an `if` to a `while` because other implementations allow things like `--preserve=mode,mode` or `conv=sync,sync`. (If we decide this is a bug rather than a feature, we should at least fix the error message to be clear that we're rejecting the *duplication*, not the option itself.) I've also fixed the ^C behavior by simply adding a direct SIGINT handler rather than trying to be clever inside the read loop (which is why we weren't handling the SIGINT until the read returned). I've also removed `strstarteq` and just added the '=' to each literal when calling regular `strstart`. Plus basic tests.
2019-07-09dd: fix seek= on stdout.Elliott Hughes
2019-06-29More toysh flow control plumbing.Rob Landley
2019-06-25Start over on toysh.Rob Landley
Basic line continuation logic (to prompt with $PS2). Doesn't use result yet.
2019-06-24diff: fix diff of stdin for systems without /tmp.Elliott Hughes
xtempfile() alreay does the right thing, so switch to that. Also use xsendfile() for the actual copying. Fixes the cat tests on Android.
2019-06-21bc: fix a few bugs found in upstreamGavin Howard
2019-06-19Avoid a double-definition (iphdr) from netinet/in.h and linux/ip_tunnel.h by ↵Mike Bennett
locally defining the single constant definition ip.c uses (IP_DF) if not already defined.
2019-06-12bc: fix previous patchGavin Howard
I put the check into the wrong if. That was my bad. Again.
2019-06-11bc: fix a bug in powerGavin Howard
This bug is that an error should be returned when the user tries to take 0 to a negative power, since that is undefined, but bc would return 0.
2019-05-10Walk -M /dir:/dir0:/dirN in man.makepost
Iterate over MANPATH and ordered sections using a manpath() helper equivalent of indenting logic of man x, man 1 x, and man -k each with a strsep loop.
2019-05-01man: support MANPATH.Elliott Hughes
(This and `git clone` is how I use the latest man7.org pages all the time instead of my system's man pages.)
2019-04-29Search name and first line with man -k regex.makepost
Exec -k value as regex on basename, and on the first content line outside a tag or on a referenced see-other, whichever appears earlier. Reuse zcat choice as a function when looping over files. Fix \-\- and glob.h include leftover. Handle man-pages example newlines. Clarify the todos, naming package and issue. Remaining items are more of a wishlist than a plan. Remove `<1>2` because it doesn't let `-k .` work, please look into that.
2019-04-26Add -M and switch test suite to use it (so test doesn't need to run as root).Rob Landley
2019-04-26Read .gz/.xz man pages and check sections in "man man" order.Rob Landley
2019-04-26more: better behavior with directories.Elliott Hughes
Also fix the non-tty output. Also tweak our output so the tests pass with TEST_HOST=1 too.
2019-04-22vi.c changes to vi cmd executionJarno Mäkipää
Reimplemented to command mode execution to follow vi cmd pattern. (REG)[COUNT0]{CMD}[COUNT1]<MOV>(SYM) Most of the moves can be executed intependently or before command, some require character after. (possibly with utf8) Some of the commands do not require move, such as D, J, dd, yy, x... There is also tons of special cases where move behaves differently depending on command. For example 1cw and 1ce appear to be the same but 1dw and 1de are not... Most of the operations still need reimplementing and lots of cleanup in order them to behave correctly refactored word move to work with utf-8

2019-04-21A little more cleanup on gzip.Rob Landley
2019-04-21Promote tar.Rob Landley
There's probably more to do, but it seems usable at this point.

2019-04-21man: WhitespaceRob Landley
2019-04-20Implement man.makepost@firemail.cc
To look up docs on my netbook and server. Practically deroff.1, with heuristic for where to put spaces and newlines. How would you simplify file resolution and bzcat? What have I got wrong when escaping slashes, because while \-\^\- is -- ok, \-\- becomes -\-, e.g. in git-pull.1?
