`this-original-command' is supposed to be for the command that
we're *not* executing because of key remapping, therefore it doesn't
make sense to set it to the command we're about to execute.
* yasnippet.el (yas--fallback): Set `this-command'.
Probably nobody wants a snippet `key` with a trailing space. It can
be hard to differentiate from a `key` without trailing space. The
default `<TAB>` behavior of yasnippet will never expand these.
* yasnippet.el (yas--parse-template): Ignore trailing spaces in snippet
definitions.
* yasnippet-tests.el (deftest ignore-trailing-whitespace): New test for
new behavior.

This prevents snippets from a parent mode from overriding those of the
major-mode's (or yas--extra-modes). Snippets of ancestor modes may
still override snippets of some other ancestor modes, but hopefully this
won't cause much trouble in practice.

* yasnippet.el (yas--modes-to-activate): Reverse result, so that parents
of yas--extra-modes and major are later in the list.
* yasnippet-tests.el (loading-with-cyclic-parenthood)
(extra-modes-parenthood): Test it.
Close#626.
* yasnippet.el (yas--field-parse-create): Use string-match-p to instead
of save-match-data, anchor regexp with \` (start of string) to instead
of (eq ... 0)
* yasnippet.el (yas--modes-to-activate): Make helper dfs function
produce the list of modes only by updating a single `explored' list,
instead of building up the list by value and having to remove
duplicated after.
* yasnippet-tests.el (visiting-compiled-snippets): New Test.
* yasnippet.el (yas--lookup-snippet-1, yas-lookup-snippet): Split new
function yas--lookup-snippet-1 from yas-lookup-snippet.
yas-define-snippets was making assumptions that happended to be true for
its current calls, but could fail if given differently formatted snippet
lists that still meet the docstring description.
* yasnippet.el (yas-define-snippets): Handle incomplete snippet lists.
Rename the existing FILE field to LOAD-FILE, and add a new SAVE-FILE to
yas--template struct. Normally they will be the same, but compiled
snippets have only SAVE-FILE because they are loaded by "compiled" code.
* yasnippet.el (yas--template): Remove field file, add load-file and
save-file.
(yas--parse-template): Update snippet-definition list in docstrings.
(yas-define-snippets): Move LOAD-FILE value to SAVE-FILE when compiling.
(yas--template-get-file): New function.
(yas--visit-snippet-file-1, yas-load-snippet-buffer,
yas-load-snippet-buffer-and-close): Use yas--template-load-file,
yas--template-save-file, or yas--template-get-file, as appropriate.
* doc/snippet-organization.org (The =.yas-compiled-snippet.el= file):
Remove caveat that is no longer relevant.
* yasnippet.el (yas--template): New yas--define-snippets-2 constructor
with arguments matching yas-define-snippets format.
(yas--define-snippets-1): Use it.
(yas--update-template): Return TEMPLATE argument.
* yasnippet.el (yas-define-snippets): Modify the list instead of
reconstructing it.
(yas-load-snippet-buffer-and-close): Replace listp and second with
cdr-safe. Use string-prefix-p rather than string-match-p.
When debugging snippets after M-x toggle-debug-on-error, errors in the
`post-command-hook' might cause `yas--post-command-handler' to be
removed. That's OK, always check that it's there before attempting any
`yas-expand-snippet' calls, since it is essential to check snippet
movement.
* yasnippet.el (yas-expand-snippet): Assert `yas-minor-mode' and
`yas--post-command-handler' active.
* yasnippet.el (yas--field-probably-deleted-p): Protect against
nil `yas--field-number'.
* yasnippet-tests.el (delete-numberless-inner-snippet-issue-562): New test
The main thrust is to get rid of the use of the `cl-struct-slots'
property which doesn't exist in Emacs-25 any more.
* yasnippet.el: Update copyright
(yas--template): Change constructor name from
`yas--make-blank-template' to `yas--make-template'
(yas--populate-template): Remove.
(yas--define-snippets-1): Use `yas--make-template'
(yas--define-snippets-1): Use `setf's
(yas-define-menu, yas--define-menu-1, yas-tryout-snippet): Use
`yas--make-template'
* yasnippet.el (yas--fallback): let-bind yas-fallback-behavior to
'yas--fallback before actually doing the fallback. Signal an error if
it's 'yas--fallback (indicating we're in an infinte loop).
* yasnippet.el (yas-installed-snippets-dir): New parameter. Set at
load time from `load-file-name'.
(yas--load-file-name): Removed.
(yas-snippet-dirs): Update docstring. Default value has symbol
`yas-installed-snippets-dir' as an alias to any bundled snippets.
(yas-snippet-dirs): Redesign for new `yas-snippet-dirs' semantics.
* yasnippet-tests.el (issue-504-tricky-jit): New test.
* yasnippet.el (yas-load-directory): Use a new `impatient-buffers'
local and call `yas--load-pending-juts' in all those at the end.
* yasnippet.el (cl-lib): Don't need `eval-and-compile'.
* yasnippet.el (yas--templates-for-key-at-point): Don't error
since this function is called very frequently on TAB. Use new
`yas--warning'.
(yas--warning): New function.
* yasnippet.el (yas-longest-key-from-whitespace): don't try again if
start-point is on whitespace.
* yasnippet-tests.el (complicated-yas-key-syntaxes): check edge case.
Example yas-key-syntaxes function.
* yasnippet.el (yas-longest-key-from-whitespace): new function.
* yasnippet-tests.el (complicated-yas-key-syntaxes): test it.
Example yas-key-syntaxes function.
* yasnippet.el (yas-shortest-key-until-whitespace): new function.
* yasnippet-tests.el (complicated-yas-key-syntaxes): test it.
Many modes put newlines in comment ender class because they have line
comments.
* yasnippet.el (yas-try-key-from-whitespace): new function.
(yas-key-syntaxes): use it in place of "^ ".
* yasnippet-tests.el (complicated-yas-key-syntaxes): test it.
