 xgqt | How can i read a file in racket?
I tried file->list but that seems to be syntax aware? | 02:55:31 |
 David | If file->lines doesn't do what you want, try https://docs.racket-lang.org/reference/file-ports.html | 11:56:13 |
| xgqt | David: yes, but i dont quite know what i want 😅
found this on on the net:
(define (next-line-it file)
(let ((line (read-line file 'any)))
(unless (eof-object? line)
(displayln line)
(next-line-it file))))
(define (show-file file)
(call-with-input-file file next-line-it))
seems to do the job for me

| xgqt | do you think there may be a better way to do it? | 12:00:59 |
 luismbo | So, you want to read the file in and display it, is that it? | 12:20:06 |
| xgqt | exactly | 12:20:18 |
| xgqt | I just got into Racket so excuse my stupid questions 😁
The most lisp/scheme i had was emacs which I use everyday but I wasn't seriously programming in elisp or similar languages. | 12:32:47 |
| luismbo | What don't you like about file->lines? | 16:02:49 |
| xgqt | weird, works ok now | 16:04:33 |
| xgqt | i got some syntax error | 16:04:44 |
| xgqt | like it tried to load that file | 16:04:52 |
| xgqt | i dont rememebr sorry | 16:05:00 |
| luismbo | You mentioned file->list before, which is different. | 16:05:30 |
| xgqt | ah, i guess thats where the error was | 16:06:12 |

solved: my docs were broken That sucks. Did you fix the docs? | 17:50:26 |
| xgqt | Mrtn Dk: they were broken on my side
I fixed the ebuild (install script) | 17:52:28 |

I fixed the ebuild (install script) Which distribution? | 17:58:53 |
| xgqt | Mrtn Dk: Gentoo(well, ebuilds are only in 2) | 18:01:52 |

Mrtn Dk: Gentoo(well, ebuilds are only in 2) Cool. I used to run Gentoo many years ago. I loved many of the features such as overlays. If I remember correctly, it will I'm theory allow me to create a patch locally, that will be applied on future updates as well. | 18:12:29 |
| xgqt | true
i prefer to create whole ebuilds rather than patches only | 18:14:09 |
| David | Guix can do similar, and uses Guile Scheme as it's config system/packaging language. | 18:25:03 |
| xgqt | David: really? didnt know i can compile from source with guix | 18:28:53 |
