/* TODO(casey): Here are our current issues
/* NOTE(allen): Should be fixed now
- Need file limit to be substantially higher than 128 (65536?)
~ file limit is now over 8 million
- Font size is too big
~ -f N option on command line, default N = 16
- Asking for a buffer to be saved if you have not modified the buffer should not save the
buffer, or perhaps more "safely", it should diff the buffer against the existing on-disk
contents and only save if there is a detected change between them.
- Search:
- Needs to be case-insensitive, or at least have the option to be
- Needs to replace using the case of the thing being replaced, or at least have the option to do so
- Bug with opening too many files where it simply no longer can switch to a buffer at all?
~ I assume this refers to a file limit issue, if not then maybe it's not actually fixed.
- Bug where opening the same buffer with open-file leads to a confusing situation
where you don't know what you're editing or something??
- Bug where replacing v4 with rectangle2 only replaces some instances???
~ For the interested programmer: the range recomputation wasn't working right so it was always
using the original range from cursor to mark. So if the string gets too long later occurances of
v4 get pushed outside of the range.
- Bug in search where extra backspaces after there are no characters yet "remembers"
how many you hit and then eats that many real characters you type?
- Display:
- Bug in scroll callback that seems to always pass the same view id instead of
the correct id for each view?
- Jumping to subsequent errors in a file seems to jump to an unrelated position
then scroll back to the actual position, which results in lots of extra scrolling
- Need a way of highlighting the current line like Emacs does for the benefit
of people on The Stream(TM)
- Some way to recenter the view so that the line containing the cursor becomes the
center line vertically.
~ cmdid_center_view
- Have buffers normalize slashes to always be forward-slash - right now I'm doing this manually
*/
/* TODO(casey): Here are our current issues
- High priority:
- Would like the option to indent to hanging parentheses, equals signs, etc. instead of
always just "one tab in from the previous line".
- Actually, maybe just expose the dirty state, so that the user can decide whether to
save or not? Not sure...
- Replace:
- Needs to be case-insensitive, or at least have the option to be
- Needs to replace using the case of the thing being replaced, or at least have the option to do so
- Auto-complete doesn't pick nearby words first, it seems, which makes it much slower to use?
- Bug with not being able to switch-to-corresponding-file in another buffer
without accidentally bringing up the file open dialog?
- Display:
- Need a word-wrap mode that wraps at word boundaries instead of characters
- Need to be able to set a word wrap length at something other than the window
?FIXED First go-to-line for a file seems to still just go to the beginning of the buffer?
Not sure Allen's right about the slash problem, but either way, we need some
way to fix it.
- Need a way of highlighting the current line like Emacs does for the benefit
of people on The Stream(TM)
- NOTE / IMPORTANT / TODO highlighting? Ability to customize? Whatever.
- Some kind of parentheses highlighting? I can write this myself, but I
would need some way of adding highlight information to the buffer.
- Indentation:
- Multiple // lines don't seem to indent properly. The first one will go to the correct place, but the subsequent ones will go to the first column regardless?
- Would like the option to indent to hanging parentheses, equals signs, etc. instead of
always just "one tab in from the previous line".
- Crash bug with paste-and-indent that sometimes leaves things unindented then crashes
- Need to have better indentation / wrapping control for typing in comments.
Right now it's a bit worse than Emacs, which does automatically put you at
the same margin as the prev. line (4coder just goes back to column 1). It'd
be nice if it go _better_ than Emacs, with no need to manually flow comments,
etc.
- Up/down arrows and mouse clicks on wrapped lines don't seem to work properly after the second wrap
(eg., a line wrapped to more than 2 physical lines on the screen.)
- Buffer management:
- Bug in view iteration such that buffer_id is sometimes set to 0, so you can't find the view
for a buffer?
- Have buffers normalize slashes to always be forward-slash - right now I'm doing this manually
- Switch-to-buffer with no typing, just return, should switch to the most recently
used buffer that is not currently displayed in a view.
- Kill-buffer should perform this switch automatically, or it should be easy
?FIXED Kill-buffer should perform this switch automatically, or it should be easy
to build a custom kill buffer that does
- Seems like there's no way to switch to buffers whose names are substrings of other
buffers' names without using the mouse?
- Also, mouse-clicking on buffers doesn't seem to work reliably? Often it just goes to a
blank window?
- Need auto-complete for things like "arbitrary command", with options listed, etc.,
so this should either be built into 4ed, or the custom DLL should have the ability
to display possible completions and iterate over internal cmdid's, etc. Possibly
the latter, for maximal ability of customizers to add their own commands?
- Default directory for file open / build search should be that of the current
buffer, not tracked separately? Probably I should code this on my own.
- Macro recording/playback
