Problem: Named function arguments are never optional.
Solution: Support optional function arguments with a default value. (Andy
Massimino, closes#3952)
Problem: Support for user commands is spread out. No good reason to make
user commands optional.
Solution: Move user command support to usercmd.c. Always enable the
user_commands feature.
Problem: A BufReadPre autocommand may cause the cursor to move.
Solution: Restore the cursor position after executing the autocommand,
unless the autocommand moved it. (Christian Brabandt,
closes#4302, closes#4294)
Problem: Macros for MS-Windows are inconsistent, using "32", "3264 and
others.
Solution: Use MSWIN for all MS-Windows builds. Use FEAT_GUI_MSWIN for the
GUI build. (Hirohito Higashi, closes#3932)
Problem: MS-Windows: inconsistent selection of winpty/conpty.
Solution: Name option 'termwintype', use ++type argument and "term_pty" for
term_start(). (Hirohito Higashi, closes#3915)
Problem: Cannot have a local value for 'scrolloff' and 'sidescrolloff'.
(Gary Holloway)
Solution: Make 'scrolloff' and 'sidescrolloff' global-local. (mostly by
Aron Widforss, closes#3539)
Problem: Giving error messages is not flexible.
Solution: Add semsg(). Change argument from "char_u *" to "char *", also
for msg() and get rid of most MSG macros. (Ozaki Kiichi, closes
#3302) Also make emsg() accept a "char *" argument. Get rid of
an enormous number of type casts.
Problem: Text property highlighting is off by one column. (Bjorn Linse)
Solution: Update text property highlighting earlier. Let it overrule syntax
highlighting.
Problem: line2byte() gives wrong values with text properties. (Bjorn Linse)
Solution: Compute byte offsets differently when text properties were added.
(closes#3718)
Problem: Using sign group names is inefficient.
Solution: Store group names in a hash table and use a reference to them.
Also remove unnecessary use of ":exe" from the tests. (Yegappan
Lakshmanan, closes#3715)
Problem: Placing signs can be complicated.
Solution: Add functions for defining and placing signs. Introduce a group
name to avoid different plugins using the same signs. (Yegappan
Lakshmanan, closes#3652)
Problem: Pointer ownership around fname_expand() is unclear.
Solution: Allow b_ffname and b_sfname to point to the same allocated memory,
only free one. Update comments.
Problem: Cannot get the script line number when executing a function.
Solution: Store the line number besides the script ID. (Ozaki Kiichi,
closes#3362) Also display the line number with ":verbose set".
Problem: Using an external diff program is slow and inflexible.
Solution: Include the xdiff library. (Christian Brabandt, closes#2732)
Use it by default.
Problem: Vim may block on ch_sendraw() when the job is sending data back to
Vim, which isn't read yet. (Nate Bosch)
Solution: Add the "noblock" option to job_start(). (closes#2548)
Problem: ":profdel func" does not work if func was called already.
(Dominique Pelle)
Solution: Reset uf_profiling and add a flag to indicate initialization was
done.
Problem: Not easy to switch between prompt buffer and other windows.
Solution: Accept CTRL-W commands in Insert mode. Start and stop Insert mode
as one would expect.
