Can we use RPC, HTTP or download function in Adept?

[Spoiledpay]

Hello! Do we have the future possibility of having download, RPC, CUrl functions in Adept?

include / printf, sprintf /

include / exit /

include / read, write, close /

include / memcpy, memset /

include <sys/socket.h> / socket, connect /

include <netinet/in.h> / struct sockaddr_in, struct sockaddr /

include / struct hostent, gethostbyname /

include <curl/curl.h>

Yes,

I will soon add cross-platform cURL to standard library (since it's so common it makes sense there).

Will update you within a day or two depending on how long it takes

[IsaacShelton]

curl/curl.adept is now in the standard library!

You can just use it straight out of the box like you would expect.

import 'sys/cstdio.adept'
import 'curl/curl.adept'

func main {
    curl *CURL
    res CURLcode

    curl = curl_easy_init()

    if(curl) {
        curl_easy_setopt(curl, CURLOPT_URL, 'https://example.com')

        /* specify certificate bundle (only required for windows) */
        #if __windows__
            curl_easy_setopt(curl, CURLOPT_CAINFO, 'curl-ca-bundle.crt')
        #end

        /* example.com is redirected, so we tell libcurl to follow redirection */
        curl_easy_setopt(curl, CURLOPT_FOLLOWLOCATION, 1)

        /* Perform the request, res will get the return code */
        res = curl_easy_perform(curl)

        /* Check for errors */
        if(res != CURLE_OK) fprintf(stderr, 'curl_easy_perform() failed: %s\n', curl_easy_strerror(res))

        /* always cleanup */
        curl_easy_cleanup(curl)
    }
}

Note for usage on Windows:

Must have access to libcurl-x64.dll and (optionally) curl-ca-bundle.crt at runtime.

With SSL certificate validation

If you want to be able to verify SSL certificates, the newer versions of curl on Windows require that you specify a certificate bundle:

curl_easy_setopt(curl, CURLOPT_CAINFO, 'curl-ca-bundle.crt')

The curl-ca-bundle.crt and libcurl-x64.dll files are automatically provided when you build your program for the first time, but you can replace them with your own if you want. You can obtain them manually from https://curl.se/download.html.

Without SSL certificate validation

Although not recommended, you can disable SSL certificate validation (so that curl-ca-bundle.crt is not required on Windows):

curl_easy_setopt(curl, CURLOPT_SSL_VERIFYPEER, 0)

Cross compilation support

Cross-compilation to Windows of programs that use curl/curl.adept is fully supported.

Note for usage on macOS:

No runtime dependencies required, the curl dynamic libraries come with macOS by default.

Note for usage on Linux:

curl shared libraries must be installed.

For compilation, the development package may need to be installed (e.g. libcurl4-openssl-dev for debian-based distros)

Also, the latest nightly of v2.7 is required to use curl/curl.adept (it uses recent features and fixes)
