- Use a standard scratch buffer instead of a new 'buftype', functions
like curbufIsChanged() already have special handling for scratch bufs.
- Cleanup some stuff from the previous merge.
- Add support for :smagic, :snomagic. Closes#5578
Add tests for undotree().
Helped-by: Björn Linse <bjorn.linse@gmail.com>
When "curhead" points to a valid head, the value of "newhead" is
meaningless (and really should be set to null). The undo state for
a buffer is _logically_ the enum:
enum UndoState {
CurrentHead(head),
NewHead(head),
EmptyTree
}
nvim _represents_ this as: whenever `curbuf->b_u_curhead` is nonnull it
should be used as the current head, and `curbuf->b_u_newhead` is
ignored. If the there is a current head, then this will be redoed on the
next redo, and its parent will be undone on next undo. Only if
`b_u_curhead` is NULL, `b_u_newhead` will be used as the head to undo
(and it is not possible to redo). Also both can be NULL, to indicate an
empty undotree. (To be fair, this only strictly true when calling undo.c
from the outside, in some places _within_ a function in undo.c both
values might be meaningful)
Apparently `undotree()` breaks this non-abstraction, this _cosmetic_
issue can easily be fixed by `ex_substitute` also saving and restoring
`b_u_newhead`, but is doesn't reflect any error really how
`u_undo_and_forget` manipulates the _actual_ state of the undo tree.
'inccommand' allows us to expand the feature to other commands, such as:
:cdo
:cfdo
:global
Also rename "IncSubstitute" highlight group to "Substitute".
[inc_sub] is less obvious for users. Also, in the future we may want to
generalize the idea of a "preview buffer", or "incremental commands"
besides :substitute.
- Eliminate/isolate static/global variables
- Remove special-case parameter from buflist_new()
- Remove special-case ECMD_RESERVED_BUFNR
- To determine when u_undo_and_forget() should be done, check
b_changedtick instead of a heuristic.
- use mb_string2cells() instead of strlen() to measure the :sub patterns
- call ml_close() before buf_clear_file(). Avoids leaks caught by ASan.

The 'dump and read back mark " from a closed tab' test needs to actually
create a second tab. Since it wasn't doing so, the 'q!' command caused
nvim to exit and the subsequent 'qall' command fails.
API level is disconnected from NVIM version. The API metadata holds the
current API level, and the lowest backwards-compatible level supported
by this instance.
Release 0.1.6 is the first release that reports the Nvim version and API
level.
metadata['version'] = {
major: 0,
minor: 1,
patch: 6,
api_level: 1,
api_compatible: 0,
api_prerelease: false,
}
The API level may remain unchanged across Nvim releases if the API has
not changed.
When changing the API,
- set NVIM_API_PRERELEASE to true
- increment NVIM_API_LEVEL (at most once per Nvim version)
- adjust NVIM_API_LEVEL_COMPAT if backwards-compatibility was broken
api_level_0.mpack was generated from Nvim 0.1.5 with:
nvim --api-info

The API level may remain unchanged across Neovim releases if the API has
not changed.
When changing the API the CMake variable NVIM_API_PRERELEASE is set to
true, and NVIM_API_CURRENT/NVIM_API_COMPATIBILITY are incremented
accordingly.
The functional tests check the API table against fixtures of past
versions of Neovim. It compares all the functions in the old table with
the new one, it does ignore some metadata attributes that do not alter
the function signature or were removed since 0.1.5. Currently the only
fixture is 0.mpack, generated from Neovim 0.1.5 with nvim --api-info.
Closes#5449
A file containing the string "vim" followed by a very large number in a modeline
location will trigger an overflow in getdigits() which is called by
chk_modeline() when trying to parse the version number.
Add getdigits_safe(), which does not assert overflows, but reports them to the
caller.
Problem: Mark " is not set when closing a window in another tab. (Guraga)
Solution: Check all tabs for the window to be valid. (based on patch by
Hirohito Higashi, closesvim/vim#974)

Problem: When using Insert mode completion but not actually inserting
anything an undo item is still created. (Tommy Allen)
Solution: Do not call stop_arrow() when not inserting anything.

In Vim,
:echo system('cat - &', 'foo')
works because for both system() and :! Vim writes input to a temp file and uses
shell syntax to redirect the file to the backgrounded `cat` (get_cmd_output()
.. make_filter_cmd()).
In Nvim,
:echo system('cat - &', 'foo')
fails because we write the input directly via pipes (shell.c:do_os_system()),
but (per POSIX[1]) backgrounded process input stream is redirected from
/dev/null (unless overridden by shell redirection; supported only by some shells
[2]), so our writes are ignored, the process exits quickly, and if we are
writing data larger than the buffer size we'll see EPIPE.
This still works:
:%w !tee > foo1358.txt &
but this does not:
:%w !tee foo1358.txt &
though it *should* (why doesn't it?) because we still do the temp file dance
in do_bang() .. do_filter().

These tests are essentially affirming a regression vs Vim. In Vim,
:echo system('cat - &', 'foo')
returns "foo", because Vim internally wraps the command with shell-specific
syntax to redirect the streams from /dev/null[1].
That can't work in Nvim because we use pipes directly (instead of temp files)
and don't wrap the command with shell-specific redirection syntax.

The previous form was passing because it happens immediately before this form;
but on a very fast(?) server the screen check might miss that form. It's also
not really want we want to assert anyways.
this is consistent with vim, and is necessary for plugins that implement
their own input modes using "getchar()" and still want to do async
event processing.
Check `exists('b:term_title')` to avoid the BufReadCmd for already-initialized
:terminal buffers.
Move the test for `:argadd`.
Add a test for `:edit<CR>`.
Tweak comments and code style.
