Previously, many functions in vtable.el called 'vtable--cache',
which computed 'vtable--cache-key' based on the current selected
window and frame; this could cause vtable functions to fail or
misbehave if they were not called from the selected window and
frame that 'vtable-insert' was last called in.
Now, the vtable cache is stored with the text of the vtable, so
that functions which need to interact with some vtable text can
do so reliably without having to use the same selected window
and frame.
Also, 'vtable-update-object' has always required TABLE to be
present at point in the current buffer; now its docstring states
this.
* lisp/emacs-lisp/vtable.el (vtable--current-cache)
(vtable--cache-widths, vtable--cache-lines): Add.
(vtable-insert): Save cache in 'vtable-cache.
(vtable--ensure-cache, vtable--recompute-cache): Inline into
'vtable-insert'.
(vtable--widths, vtable--cache): Delete.
(vtable-update-object): Use 'vtable--current-cache' and
update docstring. (Bug#69837)
(vtable-remove-object, vtable-insert-object): Use
'vtable--current-cache' and save cache in 'vtable-cache'.
(vtable--sort, vtable--alter-column-width)
(vtable-previous-column, vtable-next-column): Use
'vtable--current-cache'.
* lisp/emacs-lisp/vtable.el (vtable--compute-columns): If a column
was not created with an explicit 'align' property, allow changing
this property when the column data changes from numeric to
non-numeric (or vice versa). This makes it possible to add data to
an empty table, because in a table without data all columns are
assumed to be numeric and right-aligned. (Bug#73775)
* lisp/emacs-lisp/vtable.el (vtable--insert-header-line): Ensure
proper alignment between the columns in header-line and in the
body of the table. (Bug#73032)
* doc/misc/vtable.texi (Making A Table): Document the defaults of
the various keyword parameters.
* lisp/emacs-lisp/vtable.el (vtable-insert-object): Rename
argument AFTER-OBJECT to LOCATION; allow use of index to
refer to the insertion position; add argument BEFORE.
(Bug#70664).
* etc/NEWS:
* doc/misc/vtable.texi (Interface Functions): Document the
change.
* test/lisp/emacs-lisp/vtable-tests.el
(test-vtable-insert-object): New test.
It's often necessary to update the representation of a single
object in a table (e.g a struct, whose identity does not change
when its slots'
values are changed). To do so, now the function may be called
like this:
(vtable-update-object table object)
Instead of like this:
(vtable-update-object table object object)
This also documents the behavior of the just-discovered limitation filed
as bug#69837.
* lisp/emacs-lisp/vtable.el (vtable-update-object): Make 'old-object'
argument optional. (Bug#69666)
* doc/misc/vtable.texi (Interface Functions): Update documentation.
* etc/NEWS: Add news entry.
Each element of LINE being tested is a list, the first element of
which is the value actually being represented in the table.
Previously, the 'numberp' test would always fail, because it was
being compared with the list rather than the intended value in it;
that could cause the whole table to be recomputed, sometimes
unnecessarily.
* lisp/emacs-lisp/vtable.el (vtable--recompute-numerical): Test the
car of ELEM, not ELEM itself, which is a list. (Bug#69927)
* lisp/emacs-lisp/vtable.el (vtable-insert-object): Pass in the
correct ellipsis values (bug#58370).
(vtable--insert-line): Don't bug out on missing optional arguments.
* lisp/emacs-lisp/vtable.el (vtable):
(make-vtable): Store whether the user has specified the columns.
(vtable-insert): Don't insert a header line or a header if the
user hasn't specified the columns (bug#55075).
* doc/misc/vtable.texi (Making A Table): Adjust color documentation.
* lisp/emacs-lisp/vtable.el (make-vtable): Mix more.
(vtable--compute-colors): Mix both foreground and background colors.
(vtable--make-color-face, vtable--face-blend): New functions.
(vtable--insert-line): Adjust usage.
* lisp/emacs-lisp/vtable.el (vtable): Add a keymap cache.
(make-vtable): Allow dragging the divider.
(vtable-insert): Don't put the table keymap over the entire line
-- avoid the divider, which has its own keymap.
(vtable--drag-resize-column): Adjust to the in-buffer divider
dragging.
* lisp/emacs-lisp/vtable.el (vtable--insert-header-line): Allow
resizing by dragging headers.
(vtable--drag-resize-column): New function.
(vtable-narrow-current-column): Refactor out common bits.
(vtable--alter-column-width): To here.
(vtable-widen-current-column): Rewrite to use
vtable-narrow-current-column.
* lisp/emacs-lisp/vtable.el (vtable-narrow-current-column)
(vtable-widen-current-column): Allow using the prefix to say how
much to narrow/widen the columns.
* lisp/emacs-lisp/vtable.el (vtable--insert-header-line): Don't
insert the divider at the end.
(vtable-narrow-current-column, vtable-widen-current-column): Don't
error out when being called on the divider.
* doc/misc/vtable.texi (Making A Table): Document it.
* lisp/emacs-lisp/vtable.el (vtable): Add a divider slot.
(make-vtable): Accept :divider and :divider-width arguments.
(vtable--insert-line, vtable--insert-header-line): Display the
divider.
* doc/misc/vtable.texi (Making A Table): Document it.
* lisp/emacs-lisp/vtable.el (vtable): Add :row-colors.
(make-vtable): Ditto.
(vtable--compute-colors, vtable--color-blend): New functions.
(vtable--insert-line): Take a line number argument and adjust
callers.
* doc/misc/vtable.texi (Making A Table): Document it.
* lisp/emacs-lisp/vtable.el (vtable): Add a column color element.
(make-vtable): Use it.
(vtable--insert-line): Insert the colors here.
