histedit: make sure mesg is only used after pick or edit It doesn't really make sense to use mesg after a fold or drop, or after another mesg. it currently "works" as intended, but the behaviour is confusing and not useful, better abort the operation as it's probably not what the user intended.

got tag -V is like tag -l with verification, fix option-conflicts accordingly

tog man page: Be more precise when first introducing split layout terminology.

tog man page: improve spacing with a .Pp before global key bindings

tog man page: tweak documentation of vertical/horizontal split for clarity

tog: only request commits when child hsplit increases Fix bug introduced in 3c1dfe12b3 that fails to properly populate child log views due to incorrect request_log_commits() calls: (1) when increasing the bottom hsplit in a ref/log splitscreen; and (2) when reopening a child log view after closing a resized child log view: $ TOG_VIEW_SPLIT_MODE=h tog ref return # open log view in bottom split 4+ # increase log (child/bottom) split *new log lines are not populated* q # close log view return *commits are not loaded* ok stsp@

tog: adjust view line offset when resizing hsplit Squish bug that can move the selection cursor offscreen when resizing horizontal splits due to bogus offset: $ TOG_VIEW_SPLIT_MODE=h tog # 80x24 22j return # open diff view in a hsplit tab # focus log (top) split 10+ # increase top split by 10 lines 22j return # open diff view in a hsplit F # toggle fullscreen diff view tab # focus log (parent) view in fullscreen *selection cursor will be off the bottom of the screen* ok stsp@

tog: enable moving to prev/next blame line in diff view Blame/diff view counterpart of log/diff <,.> key maps to traverse commits corresponding to each line of the annotated file from the diff view. Includes fix from stsp@ to work while the file is still annotating. ok stsp@

tog: make 'S' switch split mode irrespective of the view Always switch internal split state and redraw view according to the constraints of the new mode. suggested by and ok stsp@

portable: regress: fix sed parsing When making sed's command-line flags portable, don't split on $@ before parsing it, as this won't preserve the original string which needs passing to sed unmodified if it's never had to be changed.

portable: regress: add test stage to all runs Whenever a CI change is made, also run the test suites. This is enabled for just Ubuntu and FreeBSD for now.

portable: regress: improve sed handling When massaging sed command strings, to handle the differences between "-i ''" not meaning the same thing on non-BSD systems, this previously used a bashism to determine the positional arguments. Instead, defer to using a loop which doesn't rely on bashisms.

portable: regress: remove backticks from string Remove erroneously-placed backticks when describing a lack of GNU coreutils.

portable: regress: make OS-detection sh-compatible Don't rely on $OSTYPE being available, which it isn't in strict POSIX mode. Ubuntu's sh is often alised to dash, and hence this fails. Instead, default to using the output from 'uname'.

portable: ci: add ubuntu Add Ubuntu as a dedicated CI environment. By default, sh is aliase to dash which often provides interesting challenges for portability, so making this work here is a good thing as mistakes will be spotted earlier.

portable: regress: harden coreutils check When running tests on non-Linux systems, it was just assumed that GNU coreutils had been installed. This meant that the wrapper commands for date/ln on those systems always had gdate and gln installed. Rather than assume that, check to see if the GNU coreutils versions as present, and if not echo a warning.

portable: regress: set PLATFORM when running direct PLATFORM is populated when running via `./configure && make` but this isn't guaranteed if an individual test is run directly, such as `regress/cmdline/tag.sh`. In such cases, PLATFORM will be empty, but we still want to use it. Since we test for non-linux values, only set PLATFORM if we're running on Linu so that the correct commands are used.

portable: remove stale comments Remove comments which are no longer required.

tog: implement +/- keymaps to resize the focussed split Increase/decrease the currently active split. New dimensions persist for the tog session, irrespective of subsequent closures and new child views. suggested by and ok stsp@

tog: implement global 'S' key map to switch split mode If in a vertical (horizontal) split, switch to horizontal (vertical), and make new split mode persist. ok op@

use got_privsep_flush_imsg instead of reinventing it ok stsp@

get rid of unneeded recv_imsg_error calls got_privsep_recv_imsg users don't need to bother to look whether the imsg type is GOT_IMSG_ERROR because got_privsep_recv_imsg already takes care of that and turns GOT_IMSG_ERROR into `struct got_error's automatically. ok stsp@
