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

/* BUGS
Assertion: w:\apps\4coder\source\build\4ed_app.dll
w:\apps\4coder\source\code\4ed_file_view.cpp
Line: 3261
Expression: view->prev_cursor_pos == view_get_cursor_pos(view)
Crash in buffer_get_line_index_range - it doesn't check for lines == 0, which can be the case?
*/
/* TODO(casey): Here are our current issues
- High priority:
- Buffer switching still seems a little bit broken. I find I can't reliably hit switch-return
and switch to the most recently viewed file that wasn't one of the two currently viewed buffers?
- High-DPI settings break rendering and all fonts just show up as solid squares
- Pretty sure auto-indent has some bugs. Things that should be pretty easy to indent
properly even from only a few surrounding lines seem to be indented improperly at the moment
- Multi-line comments should default to indenting to the indentation of the line prior?
- 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?
- Up/down arrows and mouse clicks on wrapped lines don't seem to work properly with several wraps.
(eg., a line wrapped to more than 2 physical lines on the screen often doesn't work anymore,
with up or down jumping to totally wrong places, and mouse clicking jumping to wrong places
as well - similarly, scrolling breaks, in that it thinks it has "hit the end" of the buffer
when you cursor down, but the cursor and the rest of the wrapped lines are actually off
the bottom of the screen)
- Search:
- Should highlight all matches in the buffer
- 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?
- 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...
- 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?
- There are often repaint bugs with 4coder coming to the front / unminimizing, etc.
I think this might have something to do with the way you're doing lots of semaphore
locking but I haven't investigated yet.
- 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.
- 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:
- 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?
- 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.
- It should never reindent text in comments that it doesn't know how to indent - eg., in a comment block, it shouldn't decide to move things around if it doesn't know what they are
- Sometimes when I hit [ it inserts a [ _and_ a space? I think this is related to the auto-indent?
- 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
- 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?
- Buffer switch display should always show the buffer _it will switch to when you hit return_
as the first buffer in the list.
- 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?
- Still can't seem to open a zero-length file?
- 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
- I'd prefer it if file-open deleted per-character instead of deleting entire path sections
- 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
- To-do list dependent on project?
- 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...
