Feature Overview
STRDSUM() sums two numerable strings.
- The number of digits it can handle exceeds the 32-bit limit. (Probably as long as the system will allow.)
- Match the string length to the longer of the two arguments.
- Negative values and values after the decimal point cannot be handled.(Insert a period in the output result.)
- This function consumes 63 Token.
This code may cause errors in versions prior to 0.2.5c.
?strdsum('32768','32768') -- 65536
?strdsum('500','000500') -- 001000
?strdsum('900109','123456') -- 1023565

Hello @zep
One of my game players reported this.
It seems that Pico8 games downloaded from Steam sometimes fail to start when a controller is connected.
Target game in which the bug occurred.
https://store.steampowered.com/app/1448220/KONSAIRI/
Running environment
- Apple silicon Mac.
- Gamepad "Sony PlayStation® DualSense™ Wireless Controller" ----STORE PAGE.
- Using Steam's controller linkage function (Bluetooth).
- Exported cart pico8 version 0.2.2c (also occurs in 0.2.5e)
Crash report

Thank you for your cooperation.
In the screenshot, the pause menu does not appear.
But in the case of GIF output, the pause menu seems to appear.
(version 0.2.5c)
Feature Overview
BPACK() pack the value of the bit specification with bit width.
- By packs in the direction of low bits when multiple bit values are specified.
- By setting [number s] to a negative value, bit pack can be started from the decimal point.
- If there are fewer bit-width elements relative to the value to be packed, the bit-width elements are rotated.
- This function consumes 37 Token.
v=bpack({8,4},0,0xff,0xb)
?tostr(v,1) -- 0x00ff.b000 (bit-left-shift:0)
v=bpack({8,4},8,0xff,0xb)
?tostr(v,1) -- 0xffb0.0000 (bit-left-shift:8)

Feature Overview
BUNPACK() slice the value with bit width.
- By specifying the argument after [number w], a value of up to 32 bits can be sliced.

- This function consumes 30 Token.
a,b=bunpack(0xf8,4,4,4) -- Value, First bit-shift, bit-width, ...[bit-width] ?a -- 15 (0xf) ?b -- 8 (0x8) |

Feature Overview
TTABLE() returns the table if the argument is a table.
- Returns FALSE if not a table.

- Simultaneously check the type and reference the contents inline, as in
type(tbl)=='table' and tbl.
- This function consumes 10 Token.
tbl = '1 5 10' -- Default value.
tbl = ttable(tbl) or split(tbl, ' ') -- tbl = {1, 5, 10}
----
----
-- Thereafter, the tbl is not initialized even if there are changes to the elements of the tbl.
tbl = ttable(tbl) or split(tbl, ' ')

Feature Overview
REPLACE() Replaces the specified string with the specified string.
- The first argument string replaces all matches to the second argument string with the third argument string.
- After the fourth and fifth words, you can further specify the search match and the words to be replaced.
- This function consumes 58 Token.
--"str" becomes "string for replace".
str = replace('[test] for replace', '[test]', 'string')

Feature Overview
SUM() returns the sum of the numbers in the given arguments.
- If the argument contains nil or false, the result will not be correct.
- If too many arguments are given, Out of memory is returned. (In the sample, up to 710 arguments)
- This function consumes 15 Token.
If you are concerned about some of the problems, consider using the "More Argments Ver" code.
Other tuple trick code: INRNG()
Feature Overview
INRNG() Tests if the value is between the lowest and highest values.
- Tests that the specified value is within a range.
- This function consumes 10 Token.
--[true] in range value inrng(5,1,10) --[true] lowest range value inrng(1,1,10) --[true] highest range value inrng(10,1,10) --[false] out of range value inrng(0,1,10) --Player:1 any key inrng(btn(),0x1,0xff) --Player:2 any key inrng(btn(),0x100,0xff00) |

One-off characters [8 chars of raw binary data] print unnaturally.
Or I may not understand this feature.
I was aware that "\^.00000000" would print nothing.
Feature Overview
RCEACH() performs a two-dimensional loop in a single function.
- The rectangle value arguments correspond to [table] {x,y,w,h} and [string] "x y w h".
- You can refer to the current x and y values in the specified function.
- This function consumes 50 Token.
rceach({16,16,32,32},function(x,y,r)
local c=(x+y)%8+8
pset(x,y,c)
end)

One of KNUTIL's functions, the object generated by EXRECT(), has a rectangle value format to be used for the RCEACH() argument.

Feature Overview
TMAP(), like foreach(), applies the function of the second argument to each element of the table.
- Usage is almost the same as foreach(), plus index values can be referenced within the function.
- The specified table is returned. (TMAP() nested functions can be applied multiply)
- The return value in the function specified in the argument can update each element of the table.
- This function consumes 31 Token.
local t={
'toast'
,'letus'
,'bacon'
,'cheese'
}
t=tmap(t, function(v,i)
?i..'..'..v
end)
--------
t=tmap(t, function(v,i)

return v
end)

Feature Overview
CAT() concatenates two or more tables.
- The second and subsequent arguments are added to the table elements of the first argument.
- Returns a concatenated table.
- The table used for the first argument is updated. (destructive)
- This function consumes 39 Token.
local tbl_1 = {'a'}
local tbl_2 = {'b', 'c'}
cat(tbl_1, tbl_2)
?tbl_1[1] -- a
?tbl_1[2] -- b
?tbl_1[3] -- c
-- Only primary elements can be cloned by specifying an empty table for the first argument.
local tbl = {1, 2, 3}
local tbl_dup = cat({}, tbl)
tbl[1] = 256
?tbl_dup[1] -- 1
?tbl_dup[2] -- 2

Hello.
I want to use the clipboard to paste SFX data to another console as shown in the image below.
With the current (0.2.4b) function of PICO-8, you can only paste SFX data on the same console.
It would be simpler to share sound effects if they could be pasted to the clipboard in a format like
[gfx] wwhhpp... [/gfx)
In what situations do you use these conversions?
hexnumber = '3xz'
--A
tonum(hexnumber,1) : 768 (0x0300.0000)
--B
tonum("0x"..hexnumber,4) : 0 (0x0000.0000)
--C
tonum('0x'..hexnumber) : -- NO VALUE --([nil]) |
Example
I want "nil" to be returned when I use a character as an identifier. Therefore, I use the "C" conversion.
hexstr = '108000789$'
hexval = TONORM(hexstr) -- Normalize the value [number boolian nil], otherwise it remains a string.
hextable = {}
if type(hexval) == 'string' then
foreach(split(hexstr, 3), function(v)
add(hextable, tonum('0x' .. v))
end)
end
-- Handle hexadecimal conversions without being converted to numbers by normalization.
-- Only the value of number is stored in the hextable.
-- "$" is not stored.
