Raw Blame History

/* TODO(casey): Here are our current issues
- Display:
- 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)
- Need a way of changing some things visually so we can indicate the modal state (this has
to be something very obvious - ideally something like
1) Change the line highlight color
2) In modal mode, highlight the whole selected region (mark to cursor) potentially?
- Some way to recenter the view so that the line containing the cursor becomes the
center line vertically.
- NOTE / IMPORTANT / TODO highlighting? Ability to customize? Whatever.
- 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".
- 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 got _better_ than Emacs, with no need to manually flow comments,
etc.
- Buffer management:
- Have buffers normalize slashes to always be forward-slash - right now I'm doing this manually
- 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?
- Macro recording/playback
NOTE(allen): Things that were on the issue list that are now fixed
- Need a way of calling things by name, so infrequently used functions won't need keybindings
- Need a way of changing some things visually so we can indicate the modal state (this has
to be something very obvious - ideally something like
1) Change the cursor color
2) Change the header bar color?
- Need a way to set the theme from the custom config file so I don't have to pick it every
time.
- 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
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?
- Scroll speed seems to slow. It's behind where I am a lot of the time. Should be
_much_ more accelerated than it is, I think - presumably this will be tunable?
- Crash bug with paste-and-indent that sometimes leaves things unindented then crashes
