* 3902 - drop redundant redraw of recipe side on F4Kartik K. Agaram2017-06-091-0/+1
| | | | | | This change is interesting because I only updated one test to gain confidence that F4 will never redraw the recipe side. (Most of the changes are to explicitly render-all before each scenario.)
* 3881 - allow students to turn sandboxes into recipesKartik K. Agaram2017-05-271-17/+17
| | | | Thanks Juan Crispin Hernandez for the suggestion.
* 3860 - stop buffering the screen in termboxKartik K. Agaram2017-05-181-2/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | To achieve this we have to switch to a model of the screen in termbox that is closer to the underlying terminal. Before: a screen is a grid of characters writing out of bounds does nothing After: a screen is a scrolling raster of characters writing out of bounds wraps to next line and scrolls if necessary To move to the new model, it was essential that I migrate my fake screen at the same time to mimic it. This is why the first attempt (commit 3824) failed (commit 3858). This is also why this commit can't be split into smaller pieces. The fake screen now 'scrolls' by rotating screen lines from top to bottom. There's still no notion of a scrollback buffer. The newer model is richer; it permits repl-like apps that upstream termbox can't do easily. It also permits us to simply use `printf` or `cout` to write to the screen, and everything mostly works as you would expect. Exceptions: a) '\n' won't do what you expect. You need to explicitly print both '\n' and '\r'. b) backspace won't do what you expect. It only moves the cursor back, without erasing the previous character. It does not wrap. Both behaviors exactly mimic my existing terminal's emulation of vt100. The catch: it's easy to accidentally scroll in apps. Out-of-bounds prints didn't matter before, but they're bugs now. To help track them down, use the `save-top-idx`, `assert-no-scroll` pair of helpers. An important trick is to wrap the cursor before rather after printing a character. Otherwise we end up scrolling every time we print to the bottom-right character. This means that the cursor position can be invalid at the start of a print, and we need to handle that. In the process we also lose the ability to hide and show the screen. We have to show the prints happening. Seems apt for a "white-box" platform like Mu.

| | | | Revert commits 3824, 3850 and 3852. We'll redo them more carefully.
* 3824 - experiment: stop buffering in termboxKartik K. Agaram2017-04-161-2/+0
| | | | | | | | | | | | | | | | Now it's much more apparent why things are slow. You can see each repaint happening. Already I fixed one performance bug -- in clear-rest-of-screen. Since this subverts Mu's fake screen there may be bugs. Another salubrious side effect: I've finally internalized that switching to raw mode doesn't have to clear the screen. That was just an artifact of how termbox abstracted operations. Now I can conceive of using termbox to build a repl as well. (I was inspired to poke into termbox internals by http://viewsourcecode.org/snaptoken/kilo and https://github.com/antirez/linenoise)
* 3745Kartik K. Agaram2017-02-071-0/+343
| | | | | | | Stop trying to create a new layer showing how we minimize prints. Stephen's suggestion is to create a data structure that encapsulates instructions to `insert-at-cursor` for either just printing a character to screen or rendering everything. Let's try that at some point.

* 3656Kartik K. Agaram2016-11-101-1/+1
| | | | | | | | | | | | | | Periodic cleanup to replace 'reply' with 'return' everywhere in the repo. I use 'reply' for students to help reinforce the metaphor of function calls as being like messages through a pipe. But that causes 'reply' to get into my muscle memory when writing Mu code for myself, and I worry that that makes Mu seem unnecessarily alien to anybody reading on Github. Perhaps I should just give it up? I'll try using 'return' with my next student.
* 3552Kartik K. Agaram2016-10-221-1/+1
| | | | | | | | | | | | | | | | | | Stop requiring jump instructions to explicitly provide a ':label' type for jump targets. This has been a source of repeated confusion for my students: a) They'd add the ':label' to the label definition rather than the jump target (label use) b) They'd spend time thinking about whether the initial '+' prefix was part of the label name. In the process I cleaned up a couple of things: - the space of names is more cleanly partitioned into labels and non-labels (clarifying that '_' and '-' are non-label prefixes) - you can't use label names as regular variables anymore - you can infer the type of a label just from its name
* 3490Kartik K. Agaram2016-10-091-22/+22
| | | | | | | | | | | | | | | Redo commit 3457. Basically there were 3 unicode characters we changed back then: solid horizontal line: 9473 -> 9472 fuzzy horizontal line: 9480 -> 9548 fuzzy vertical line: 9482 -> 9550 The solid horizontal line has no issues, so we just redo it here. For the other two, we'll perform the substitution only when rendering html. That gives us the best of both worlds: the scenario screens render right in html, and alt-tabbing continues to be snappy when running the edit/ app.
* 3489Kartik K. Agaram2016-10-081-76/+76
| | | | | | | | | | Revert commit 3457, where I switched the unicode characters used in the edit/ app to something that doesn't render double-wide in html. It turns out that the new unicode characters made iTerm2 sluggish in alt-tabbing between windows. (Commit 3488 only fixed the screen-clearing issue.) I haven't reverted the html files. I'm going to redo commit 3457 next so the html files continue to render like they do now.
* 3457Kartik K. Agaram2016-10-061-76/+76
| | | | | Switch around some unicode characters in the edit/ app so that it renders more cleanly in html (with monospace fonts).
* 3445Kartik K. Agaram2016-10-061-16/+16
| | | | | | | Ugly that we didn't need 'screen' to provide a type in scenarios (because assume-screen expands to a definition of 'screen') but we did need a type for 'console'. Just never require types for special names in scenarios.
* 3429 - standardize Mu scenariosKartik K. Agaram2016-09-281-30/+25
| | | | | | | | | | | | | A long-standing problem has been that I couldn't spread code across 'run' blocks because they were separate scopes, so I've ended up making them effectively comments. Running code inside a 'run' block is identical in every way to simply running the code directly. The 'run' block is merely a visual aid to separate setup from the component under test. In the process I've also standardized all Mu scenarios to always run in a local scope, and only use (raw) numeric addresses for values they want to check later.

* 3391 - type abbreviations everywhereKartik K. Agaram2016-09-171-39/+39
| | | | | | | | | Well, almost. I can't use them in some places in C++ where I'm just creating a temporary reagent without passing it through transforms. Like in some unit tests. I can't use them in memory-should-contain. And there's one remaining bug: I can't use abbreviations in a couple of places in 075channel.mu.
* 3337 - first use of type abbreviations: textKartik K. Agaram2016-09-121-15/+15
| | | | | In the process I've uncover a couple of situations we don't support type abbreviations yet. They're next.
* 3052 - make edit/ render functions higher-orderKartik K. Agaram2016-06-121-5/+5
| | | | | | This required the fix of 3051 to first-class recipe support, and will next enable us to keep the cursor from moving in response to resize events.
* 2983 - migrate buttons over to sandbox/Kartik K. Agaram2016-05-191-3/+3

* 2981 - sandbox buttons implemented in edit/Kartik K. Agaram2016-05-191-44/+53
|
* 2978 - support new 'edit' button in edit/Kartik K. Agaram2016-05-191-2/+2
|
* 2977 - draw new sandbox menu in edit/Kartik K. Agaram2016-05-191-71/+71
| | | | | | | | | | | | | Doesn't work as advertised yet. This is just the render piece, and fixing all the tests. I've been careful to try to break tests for edit once I implement the button. Delete I can't ensure will break afterwards. Remember to test clicking on multiple places on the menu. Managing the screens is starting to grow onerous; maybe we need something called normalize which clears some things. But the sandbox menu can be on arbitrary lines..
* 2953 - use pgup/pgdn to scroll through sandboxesKartik K. Agaram2016-05-111-6/+6
| | | | | | In the process I've also simplified the sandbox/ app. Since it's impossible for sandbox editors to span multiple pages, we can drop all scroll support altogether.
* 2864 - replace all address:shared with just addressKartik K. Agaram2016-04-241-38/+38
| | | | | | | Now that we no longer have non-shared addresses, we can just always track refcounts for all addresses. Phew!
* 2861 - 'maybe-convert' no longer returns addressKartik K. Agaram2016-04-231-1/+1
|
* 2853 - purge get-address from edit/ appKartik K. Agaram2016-04-221-16/+37
| | | | Phew!
* 2735 - define recipes using 'def'Kartik K. Agaram2016-03-081-4/+4
| | | | | | | | | | | | I'm dropping all mention of 'recipe' terminology from the Readme. That way I hope to avoid further bike-shedding discussions while I very slowly decide on the right terminology with my students. I could be smarter in my error messages and use 'recipe' when code uses it and 'function' otherwise. But what about other words like ingredient? It would all add complexity that I'm not yet sure is worthwhile. But I do want separate experiences for veteran programmers reading about Mu on github and for people learning programming using Mu.
* 2608 - fix-up tests in sandbox/ appKartik K. Agaram2016-01-271-12/+4
| | | | | | | | | | When I first forked it from the edit/ app, I wasn't sure how to deal with changing the recipe side when the only way the program accesses it is with the untestable 'restore' hack. Now we introduce a little hook into event-loop and pass in any updated recipe side directly. In the process I've cleaned up several minor stylistic inconsistencies between edit/ and sandbox/ apps.
* 2594 - bugfixes: managing state when deletingKartik K. Agaram2016-01-231-2/+211
| | | | This required completely redesigning scrolling.
* 2590 - support scrolling through sandboxesKartik K. Agaram2016-01-221-1/+1
|
* 2585 - label sandboxes with a numberKartik K. Agaram2016-01-221-3/+3
| | | | | | | | | It also seems useful that the number maps to the name of the file the sandbox is saved in. However this mapping is currently a happy accident and not actually tested. I'm starting to switch gears and help make the editor useable with many many sandboxes. This is just the first step of several.
* 2576 - distinguish allocated addresses from othersKartik K. Agaram2016-01-191-10/+10
| | | | | | | | | | | | | | | | This is the one major refinement on the C programming model I'm planning to introduce in mu. Instead of Rust's menagerie of pointer types and static checking, I want to introduce just one new type, and use it to perform ref-counting at runtime. So far all we're doing is updating new's interface. The actual ref-counting implementation is next. One implication: I might sometimes need duplicate implementations for a recipe with allocated vs vanilla addresses of the same type. So far it seems I can get away with just always passing in allocated addresses; the situations when you want to pass an unallocated address to a recipe should be few and far between.
* rest of edit/ fixedKartik K. Agaram2015-12-151-1/+1

* 2260 - start tracing by depth rather than labelKartik K. Agaram2015-10-061-1/+1
| | | | Now we can collect all traces, just modulating the depth.
* 2183 - environment + external editor using tmuxKartik K. Agaram2015-09-121-3/+1
| | | | Thanks Jack and Caleb Couch for the idea.
* 2156 - split edit.mu into multiple filesKartik K. Agaram2015-09-051-0/+111
Now you can bring up the programming environment by saying: $ mu edit The files under edit aren't yet *layers*, though, they have a few dependencies that we need to clean up.
