Inputting Glyphs

To input glyphs, you can either use the language bar, or the prefix key, which is . The keyboard layout is shown in the image below. To input a glyph in the middle column, press the prefix key once and then the corresponding key (shown in the first column), holding Shift if it's in the upper row. To input a glyph in the last column, press the prefix key twice and then the corresponding key, shifing as before. Note that many (probably most) available glyphs currently correspond to no behavior and will error when ran.

Controls

To run your code, you can press Enter or the Run button. To edit code you already ran, click on it. Similarly, you can click on an output to put it into the input bar. You can also scroll through previously ran code with Shift+↑ and Shift+↓. To insert a newline in the code, you can press Shift+Enter.

Quads

In addition to all the quad names available normally in TinyAPL, there are additional ones:

```
⎕Debug
```
: acts exactly like
```
⊢
```
, except the input(s) are printed to the JavaScript console. Useful if you want to create your own quads and want to look at the JS structure of arrays.
```
id←⎕CreateImage size
```
: adds a blank image of size
```
size
```
, which can either be a scalar number (creating a square image) or a vector of
```
⟨height⋄width⟩
```
. Returns an
```
id
```
(which is currently a number, but it's an implementation detail) which can be used to update the image display.
```
[id] ⎕DisplayImage data
```
: renders an image, either to a new display or to the one indicated by
```
id
```
.
```
data
```
should be a real array of rank
```
2
```
or
```
3
```
(if it's of rank
```
2
```
a trailing unit axis is introduced as in
```
∧⍤0 data
```
) and the last axis must be of length
```
1
```
,
```
2
```
,
```
3
```
,
```
4
```
. If the last axis has length
```
1
```
,
```
data
```
is interpreted as grayscale; if it has length
```
2
```
, it is interpreted as grayscale + alpha, if it has length
```
3
```
, it is interpreted as RGB, if it has length
```
4
```
, it is interpreted as RGBA. In all cases,
```
0
```
is the lowest value of the channel and
```
1
```
is the highest value in the channel. All data outside this range is clamped.

[delay] ⎕PlayAnimation data

: plays an animation.

data

should be a real array of rank

. Each major cell of

data

is used as a frame for the animation, in the way described for

⎕DisplayImage

delay

is the delay between frames in seconds and defaults to

0.1

```
[mode] ⎕ScatterPlot data
```
: renders a plot.
```
data
```
should be a real array of rank
```
2
```
or
```
3
```
(if it's of rank
```
2
```
a leading unit axis is introduce as in
```
∧data
```
) and the last axis must be of length
```
2
```
. Matrices of
```
data
```
are interpreted as scatter plot datasets, with each vector of the matrix being a
```
⟨x⋄y⟩
```
pair. If
```
mode
```
is provided, it must be one of
```
"markers"
```
, which is the default and displays dots;
```
"lines"
```
, which connects the provided points (and attempts to do so smoothly);
```
"lines+markers"
```
, which displays both.
```
[start] fns ⎕_Graph end
```
: graphs functions.
```
fns
```
should be a function, a vector of functions, or a vector of pairs of functions and labels. The default labels are the representations of the functions.
```
start
```
and
```
end
```
are the start and end of the graph, respectively. The default
```
start
```
is
```
0
```
. The function is evaluated at
```
501
```
points evenly spaced between
```
start
```
and
```
end
```
.
```
[sampleRate] ⎕PlayAudio data
```
: plays audio.
```
data
```
should be a real array of rank
```
1
```
or
```
2
```
(if it's of rank
```
1
```
a leading unit axis is introduced as in
```
∧data
```
). Vectors of
```
data
```
are channels containing samples.
```
sampleRate
```
is the sample rate of
```
data
```
and defaults to
```
44100
```
.
```
data←[type] ⎕Fetch url
```
: fetches data from the web.
```
url
```
must be a string. If
```
type
```
is not provided,
```
url
```
is fetched and
```
data
```
is the text content of the result. If
```
type
```
is provided,
```
url
```
is fetched as binary and it is interpreted according to
```
type
```
:
- ```
1
```
  : bits
- ```
8
```
  : unsigned 8-bit
- ```
¯8
```
  : signed 8-bit
- ```
16
```
  : unsigned 16-bit little endian
- ```
¯16
```
  : signed 16-bit little endian
- ```
0ᴊ16
```
  : unsigned 16-bit big endian
- ```
0ᴊ¯16
```
  : signed 16-bit big endian
- ```
32
```
  : unsigned 32-bit little endian
- ```
¯32
```
  : signed 32-bit little endian
- ```
0ᴊ32
```
  : unsigned 32-bit big endian
- ```
0ᴊ¯32
```
  : signed 32-bit big-endian
- ```
0.32
```
  : 32-bit float little endian
- ```
0ᴊ0.32
```
  : 32-bit float big endian
- ```
0.64
```
  : 64-bit float little endian
- ```
0ᴊ0.64
```
  : 64-bit float big endian
64-bit integers are not provided as they cannot be losslessly loaded into float64s, TinyAPL's native real number type.
```
⎕last
```
,
```
⎕Last
```
,
```
⎕_Last
```
,
```
⎕_Last_
```
: access the result of the last successful code ran.
