tog: refactor key map -> new view initialisation Deduplicate view initialisation boilerplate and simplify new key map view requests with dispatch routine. Includes improvements suggested by stsp. ok stsp@

tog: uppercase alpha key maps that open new views ok stsp@

tog: reset view->offset when clearing log view state Don't move the selection cursor due to a bogus offset after closing child views following use of 'B', C-l, and backspace log view key maps. ok stsp@

tog: use view->resize idiom to ensure log is populated Replace view->mode == TOG_VIEW_LOG checks for requesting commits to populate the log view with calls to view->resize(). ok stsp@

tog: populate new child view log lines when switching split When switching a child log view from a h- to a v-split, new log lines are empty. Rather than (mis)trace height and (not) call request_log_commits(), let resize_log_view() do the math and request commits if needed to draw new lines. ok op@

Do not ignore error from format_author(). Found by llvm's scan-build (dead store). OK stsp

tog: blame view keymap to open log of annotated line As per stsp's TODO item: open a log view of the selected line with 'L'. helped by and ok stsp@

tog: alias J and K to > and < keybindings for diff view Use J and K to move to the next and previous commits, respectively, when the diff is loaded from the log or blame views. Patch by Mikhail ok stsp@

tog: always request commits if log height is increased Includes style improvements prompted by stsp. Previously, we would only call request_log_commits() when terminal height is increased in a splitscreen view. This fixes the case when a log view with no children is resized that can lead to empty lines: $ tog # 80x24 23j # move down to the last commit *increase terminal height to ~30 lines then reduce back to 80x24* ~5j # move down to the _last_ commit *increase terminal height to ~33 lines* *new lines are empty* ok stsp@

tog: fix sticky "loading..." status in log view hsplit Don't request commits if the log has completed loading all commits. While here, ensure the correct parent/child view requests commits when resizing a hsplit. Reported by stsp: $ tog S # switch into hsplit mode G # move to bottom and load all commits Enter # open a diff showing the initial import commit - # shrink the diff view by one line; alternatively use + to grow it *log status stuck with "loading..." in the header* ok stsp@

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@
