* 4261 - start using literals for 'true' and 'false'Kartik Agaram2018-06-171-4/+4
| | | | | | | | | They uncovered one bug: in edit/003-shortcuts.mu <scroll-down> was returning 0 for an address in one place where I thought it was returning 0 for a boolean. Now we've eliminated this bad interaction between tangling and punning literals.

* 3902 - drop redundant redraw of recipe side on F4Kartik K. Agaram2017-06-091-0/+3
| | | | | | 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.)
* 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)

* 3656Kartik K. Agaram2016-11-101-2/+2
| | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | 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. Agaram2016-10-061-17/+17
| | | | | Switch around some unicode characters in the edit/ app so that it renders more cleanly in html (with monospace fonts).
* 3445Kartik K. Agaram2016-10-061-14/+14
| | | | | | | 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. Agaram2016-09-281-20/+20
| | | | | | | | | | | | | 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. Agaram2016-09-171-28/+28
| | | | | | | | | 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. Agaram2016-09-121-9/+9
| | | | | In the process I've uncover a couple of situations we don't support type abbreviations yet. They're next.
