QUESTION
I have a per-component custom action that I would like to run before the given component is built:
...ANSWER
Answered 2021-Apr-06 at 09:51It turns out I was on the right track, except I also need to include the so-called internal package DB in the list of package DBs. Distribution.Simple.Build
exports a function called createInternalPackageDB
, which, unfortunately, we can't use wholesale (since it deletes and re-initializes the internal package DB, in effect deleting the build outputs of previous components); but we can duplicate its behaviour:
QUESTION
One may work on a haskell file in the source-dirs
directory and decide for now not to include this file in a stack build
. Is there a simple way to exclude temporarily the file form the build?
The obvious work-around is to move the file to another directory, but I hope this can be achieved inside hpack in a simple way which I did not find in the hpack docs.

Answered 2021-Feb-22 at 06:09I experience something similar on Windows when my docker containers run out of memory in WSL. I think the settings are different for Mac, but it looks like there is info here on setting the VM RAM/disk size/swap file settings for Docker for Desktop on Mac:
QUESTION
Problem: I've got a command-line tool written in Haskell that reads a data file. Upon installing the program, I'd like for the program to be able to read that data file regardless of the directory I find myself in. That is, upon installing, the path that the program knows should be aligned with the path that the installer chooses.
Initial attempt: I was directed to the section 7.6. Accessing data files from package code in Cabal (the library) and learned that I can import getDataDir :: IO FilePath
from Paths_myprog
, as long as I add Paths_myprog
to other-modules
(although Hpack auto-includes this by default) and that after installing my program, I can run it with:

Answered 2021-Feb-15 at 22:19Files listed in data-files
are already automatically installed in the right location so that Paths_pkg
will find them. Here's a minimal example:

I am writing code to send notifications to the Apple push notification servers (APNs) using PHP Laravel. It says in the documents that it requires HTTP/ HPACK header compression.
I've tried using cURL

Try adding the following to actually turn your request into a POST request.
QUESTION
I'm trying to store a simple vector of three-dimensional points in space. To do this, I'm newtype
-ing a custom Point
and manually implement the Data.Vector.Unboxed.Vector
and Data.Vector.Unboxed.Mutable
instances for it.
However, for some reason, any attempt to use such a vector ends up in an infinite loop in basicUnsafeNew
. The following program will hang:

Answered 2020-Dec-06 at 11:13Well, just unroll the newtype definition:
QUESTION
During development, I need to see what exactly I am sending or receiving using cli (it makes it easier to automate).
Normally I can put my http/1.0 header in a text file (in this case raw-http.txt
), send request, and get response from command line using openssl
.
ANSWER
Answered 2020-Dec-02 at 01:49Have you considered using something like curl for this? Ultimately you are no longer sending an exact series of bytes over a TCP socket, HTTP/2 is a very different beast. The raw-http2.txt
resembles how browsers show headers, but of course the actual on-the-wire format is very different. There's a lot more to it than just compressing the headers.
So you need something that takes a format humans can easily write/understand, and turn it into a HTTP/2 request. Curl is one of those tools but obviously doesn't take exactly your input format.

QUESTION
I'm trying to upgrade my stack version. Currently I am using Ubuntu 18.04 on a VM, and my stack version is 1.5.1 which I downloaded using sudo apt haskell-stack (I was trying to run stack setup (using the latest version) to compile a program, where stack was not found so it recommended me to install it via this method). However, I am wanting to upgrade it to the latest version. This is what I get when I run stack upgrade:
...ANSWER
Answered 2020-Aug-16 at 07:58It looks like stack was upgraded in a user-local way. Essentially, now you have two stack
executables installed: one in /usr/bin
and one in /home/claraina/.local/bin
.
That is fine. To run the new stack, you have to be sure that your PATH
has the directory /home/claraina/.local/bin
before /usr/bin
in it, so that the new stack is run instead of the old one.
Run echo $PATH
to check your path. Then, if needed, edit .bash_profile
accordingly.
After you edit that file, either log out & log in again, or start a login shell to reload the changes (for that shell).
