read or input from file or console

[jkleiser]

It would be interesting see an example of how to read or input something from file or console, if that is possible.

Hi @jkleiser,

Thanks for bringing up this issue! Currently IO is not in wax's standard library, but could be achieved through the (asm "...") expression to directly use the target language's IO routines.

Similar to the math standard library:

https://github.com/LingDong-/wax/blob/main/src/std/math.wax

An IO library could look something like:

; io.wax

(@pragma once)

(extern readfile  (param path str) (result str))
(extern writefile (param path str) (param data str))

(@if TARGET_TS
  (asm "const fs = require('fs');")
  (asm "const readfile = (path:string)=>fs.readFileSync(path).toString()\n")
  (asm "const writefile = (path:string,data:string)=>fs.writeFileSync(path,data)\n")
)

(@if TARGET_PY
  (asm "readfile = lambda path: open(path,'r').read()\n")
  (asm "writefile = lambda path, data: open(path,'w').write(data)\n")
)

; ... code for other targets ...

Then in another file

(@include "io.wax")

(let data str (call readfile "path/to/my/file.txt"))

There's still a bit of work to wrap it for all the target languages, and for reading from stdin. But yeah I am planning to include this in wax standard library soon.

Thanks!
