Raw Blame History

/* NOTE(casey): This code is _extremely_ bad and is mostly just me hacking things
around to put in features I want in advance of 4coder having them properly.
Most of the time I haven't even taken enough time to read the 4coder API
to know what I'm actually even doing. So if you decide to use the code in
here, be advised that it might be super crashy or break something or cause you
to lose work or who knows what else!
DON'T SAY I WE DIDN'T WARN YA: This custom extension provided "as is" without
warranty of any kind, either express or implied, including without
limitation any implied warranties of condition, uninterrupted use,

/* TODO(casey): Here are our current issues
- High priority:
- Seems to buggily break out of the search sometimes for no reason? (eg., you hit the end and it just drops out of the search instead of stopping?)
- Tracked this one down: I think it is because spurious mousewheel or other inputs break
out of the search. How can this be prevented?
- 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
- Deleting lines in comments is busted right now, probably because of the way I implemented my D command.
This is probably something I need to fix for myself, but it's basically a problem whereby deleting a line
sucks the next line up and indents it weirdly.
- I'd prefer it if file-open deleted per-character instead of deleting entire path sections. Deleting a whole path segment should be a different key, maybe?
- Simimlarly, it'd be nice to get another Emacs behavior in here, which is that if you start a new path name anywhere in the path, it
discards the initial part. This was where you'd have w:/temp/foo/whatever/p:/foo it would just lop off everything before the p:,
similarly in unix you would have w:/temp/foo/whatever//foo it would lop off everything before the /foo. This is to make it so
you don't have to erase the whole current path that comes up just to start typing a new path from scratch. It's nice!
- Real, robust jump-to-function (eg., no crashes and supports filtering by substring like the file picker does)
- Search:
- Should highlight all matches in the buffer
- Display:
- Dialogs like query-replace can lead to obscuring the cursor position if it happened to be on the top lines of the display
- When switching _back_ to a buffer, it seems like it loses the scroll position, instead preferring
to center the cursor? This is undesirable IMO... <<< Check this again
- I'd like to be able to hide the mark in text entry mode, and show the whole highlighted
region in edit mode - perhaps even with a magic split at the top or bottom that shows where the mark
is if it's off screen?
- 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.
- Need a way of highlighting the current line like Emacs does for the benefit
of people on The Stream(TM)
- Some kind of matching brace display so in long ifs, etc., you can see
what they match (maybe draw it directly into the buffer?)
- Indentation:
- 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.
- Buffer management:
- I'd like to be able to set a buffer to "auto-revert", so it reloads automatically whenever it changes externally
- If you undo back to where there are no changes, the "buffer changed" flag should be cleared
- File system
- When switching to a buffer that has changed on disk, notify? Really this can just
be some way to query the modification flag and then the customization layer can do it?
- I'd prefer it if file-open could create new files, and that I could get called on that
so I can insert my boilerplate headers on new files
- 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
- Arbitrary cool features:
- Once you can highlight things in 4coder buffers, I could make it so that my
metacompiler output _ranges_ for errors, so it highlights the whole token rather
than putting the cursor in a spot.
- Highlight on the screen what the completion would be if you hit TAB now (eg., if the string appears elsewhere on the screen)
- LOC count for the buffer and for all buffers summed shown in the title bar?
- Show auto-parsed #if/if/for/while/etc. statements at else and closing places.
- Automatic highlighting of the region in side the parentheses / etc.
- You should just implement a shell inside 4coder which can call all the 4coder
stuff as well as execute system stuff, so that from now on you just write
scripts "in 4coder", etc., so they are always portable everywhere 4coder runs?
- Things I should write:
- Ability to do "file open from same directory as the current buffer"
- Spell-checker
- Repeat last replace?
- Maybe search could be a permanent thing, so instead of initiating a search,
you're just _changing_ the search term with MODAL-S, and then there's _always_
a next-of-these-in... and that could go through buffers in order, to...
