* 3552Kartik K. Agaram2016-10-2212-45/+45
| | | | | | | | | | | | | | | | | | 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

| | | | | | | | | | | | | | | 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. Agaram2016-10-0811-751/+751
| | | | | | | | | | 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. Agaram2016-10-0611-751/+751
| | | | | Switch around some unicode characters in the edit/ app so that it renders more cleanly in html (with monospace fonts).
* 3445Kartik K. Agaram2016-10-0611-507/+507
| | | | | | | 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. Agaram2016-09-2812-1034/+1100
| | | | | | | | | | | | | 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. Agaram2016-09-1712-1771/+1771
| | | | | | | | | 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.
* 3369Kartik K. Agaram2016-09-151-12/+0
| | | | Fix some tests and make them less fragile.
* 3341Kartik K. Agaram2016-09-124-9/+9
| | | | | | | Process type abbreviations in function headers. Still a couple of places where doing this causes strange errors. We'll track those down next.
* 3338Kartik K. Agaram2016-09-124-6/+6
| | | | Process type abbreviations in container definitions.
* 3337 - first use of type abbreviations: textKartik K. Agaram2016-09-1212-435/+435
| | | | | In the process I've uncover a couple of situations we don't support type abbreviations yet. They're next.
* 3233 - change how Mu escapes stringsKartik K. Agaram2016-08-201-4/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | Thanks Sam Putman for helping think through this idea. When you encounter a backslash, strip it out and pass through any following run of backslashes. If we 'escaped' a single following character like C, then the character '\' would be the same as: '\\' escaped once '\\\\' escaped twice '\\\\\\\\' escaped thrice (8 backslashes) ..and so on, the number of backslashes doubling each time. Instead, our approach is to make the character '\' the same as: '\\' escaped once '\\\' escaped twice '\\\\' escaped thrice ..and so on, the number of backslashes merely increasing by one each time. This approach only works as long as backslashes aren't also overloaded to create special characters. So Mu doesn't follow C's approach of overloading backslashes both to escape quote characters and also as a notation for unprintable characters like '\n'.
* 3168 - skip loading recipe 'main' in edit/Kartik K. Agaram2016-08-123-3/+3
| | | | | | | This is part of efforts to allow students to transition gradually from the sandbox to running programs directly on the commandline, writing real scenarios, etc. Running on the commandline requires 'main', but overriding 'main' would mess up edit/ which is itself a Mu program.
* 3111Stephen Malina2016-07-142-4/+10
| | | | | Show number of instructions in the editor when a user clicks on a run instruction in the sandbox.

* 3053 - keep cursor stable on resizeKartik K. Agaram2016-06-121-1/+85
| | | | | As much as possible; if the cursor moves off screen, it still resets to top of screen.
* 3052 - make edit/ render functions higher-orderKartik K. Agaram2016-06-127-44/+44
| | | | | | 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.
* 3039 - bug fix in edit/Kartik K. Agaram2016-06-092-0/+43
| | | | Thanks Caleb Couch for finding this.
* 3038 - track down a long-standing bugKartik K. Agaram2016-06-081-25/+56
| | | | | | | | | | | | | | | | | | | | | | | | | | | In some rare situations the editor would join a line with the next when it should simply wrap to the next screen row. Thanks Caleb and Ella Couch for finally running into a situation that was easy to reproduce. The scenario diffs are misleading on this commit. I had to: a) delete the obsolete 'editor-wraps-cursor-after-inserting-characters' because it was written back when a line just large enough to fit in a single line would not wrap: | | <-- screen boundary abcde These days it will wrap after making room for the wrap indicator: | | <-- screen boundary abcd↩ e b) rename editor-wraps-cursor-after-inserting-characters-2 to editor-wraps-cursor-after-inserting-characters-in-middle-of-line c) create a new scenario demonstrating the bug: editor-wraps-cursor-after-inserting-characters-at-end-of-line
* 3025 - fix a minor annoyance in edit/Kartik K. Agaram2016-05-291-3/+157
| | | | | When I floor the down-arrow too much, don't scroll unnecessarily off the bottom of the screen. But *do* scroll if there's errors to show.
* 2990Kartik K. Agaram2016-05-201-17/+17
| | | | | | | | | | Standardize quotes around reagents in error messages. I'm still sure there's issues. For example, the messages when type-checking 'copy'. I'm not putting quotes around them because in layer 60 I end up creating dilated reagents, and then it's a bit much to have quotes and (two kinds of) brackets. But I'm sure I'm doing that somewhere..

* 2977 - draw new sandbox menu in edit/Kartik K. Agaram2016-05-197-376/+401
| | | | | | | | | | | | | 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..

* 2975Kartik K. Agaram2016-05-194-10/+11
| | | | Clean up this helper before we start redoing sandbox menubars.
* 2954 - bugfix: $systemKartik K. Agaram2016-05-112-9/+7
| | | | The actual fix is in the layer rewriting literal strings.
* 2953 - use pgup/pgdn to scroll through sandboxesKartik K. Agaram2016-05-113-59/+48
| | | | | | 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.
* 2928 - fix sandbox restore in edit/ and sandbox/Kartik K. Agaram2016-05-051-3/+7
| | | | | This had been broken ever since 2854, because we can't write tests for restore-snapshots at the moment.

* 2864 - replace all address:shared with just addressKartik K. Agaram2016-04-2411-1333/+1333
| | | | | | | Now that we no longer have non-shared addresses, we can just always track refcounts for all addresses. Phew!

| | | | Issue 1 in 2829 is now fixed.
* 2806 - bugfix: cleaning up in 'reload'Kartik K. Agaram2016-03-211-1/+1
| | | | | | | | | | | | | | | This brings back some of the complexity I thought I'd gotten rid of in 2799. The regression brought home the point that I'd forgotten to write tests for those bits. Written now. It also brought home the point that our cleanup in 'reload' has always been hacky and incomplete. It's also ugly that those tests in the sandbox/ and edit/ apps need changing (particularly when the test is about how the output doesn't change).
* 2782 - directly use string literals everywhereKartik K. Agaram2016-03-144-20/+10

* 2735 - define recipes using 'def'Kartik K. Agaram2016-03-0811-170/+170
| | | | | | | | | | | | 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.
* 2716 - more holes in immutability checksKartik K. Agaram2016-02-262-4/+4
| | | | | We're still not done. Layer 60 doesn't yet handle variables in surrounding spaces. There's probably other issues..

| | | | | | | | Thanks Nicolas Léveillé for running up against this bug: https://news.ycombinator.com/item?id=11094837 (Also noticed and fixed several subsidiary issues. This whole aspect doesn't seem fully baked yet.)
