Problem: The JSON that Nginx outputs cannot be successfully parsed by
journaldriver because Nginx prefixes it with "socrates nginx:". Adding
`nohostname` to `access_log` should solve this problem.
I borrow this from @tazjin's most recent definition of `commonHttpConfig`.
Interact with Stripe's payment_intents API endpoint.
I'm not committing the index.html that contains client-side code that interacts
with the /create-payment-intent endpoint, but it contains sensitive information,
so I'm omitting it for now.
TL;DR:
- Define POST /create-payment-intent endpoint
- Include envStripeAPIKey in Context record
- Define a top-level Stripe module for making API calls
- Define types and instances that align with Stripes request and response types
- Depend on the Req library: a higher-level library than http-client
Today @tazjin told me about Emacs's built-in project.el library, which he
recommended that I extend to support monorepo-specific tooling. It worked like a
charm!
Now when I press "<leader>f", it will resolve to either the nearest file named
default.nix or directory name .git.
Use Nix and Briefcase to easily create Haskell executables.
I'd eventually like to support something like: briefcase.buildHaskell.project
that let me define a few top-level values (e.g. ghcExtensions) and would give me
a ghci environment with the proper `.ghci` settings so that my development
environment mirrored my build environment... baby steps, though.
Per the assignment's instructions, the `Shift n` operation should treat
the *entire keyboard* like a cycle and shift that. I was erroneously
treating *each row* like a cycle and shifting those one-by-one.
This change fixes that. In addition, it also:
- Updates README.md with expected inputs and outputs
- Updates test suite
- Adds `split` dependency to {default,shell}.nix
TL;DR:
- include a default.nix to allow users to build an named executable
- emphasize in the README that the user needs Nix to build this project
- pin nixpkgs to a specific commit and fetch it from GitHub
Per my take-home assignment's reviewer's comments, with which for the record I
agree, I should generate the character->coordinate table from my existing qwerty
keyboard definition.
The best part is: by doing this I found a bug: Notice how the original '0'
character was mapped to the Coordinate (0,0)... thus every subsequent digit
key (i.e. the first row) is off-by-one.
After burning a few hours wrestling with the type system, I decided to revert to
the simpler `Server API` type instead of the `ServantT` transformer type.
The problem is that I couldn't write a MonadError instance for `RIO Context`,
which is my `AppM` (i.e. application monad). Using `throwIO` in the server
handlers results in 500 errors, which is not what I wanted. I'm still pretty
fuzzy about what's happening; I now know that exception handling in Haskell is
pretty gnaryly. I may revisit this at a later time when my knowledge is more
extensive. For now: time to fry bigger fish.
An easier abstract is for me to pass `T.Context` into `server` as an argument,
which after all is what a Reader does.
TL;DR:
- Read server, client ports from .envrc
- Define a top-level Failure type (empty for now)
- Define a top-level Success type
- Define App as RIO Context (Either Failure Success)
Long story -> short: I'd like to access my App monad from within my Servant
handlers.
While this code type-checks, I'm not sure it's working as intended. Needing to
change throwError to throwIO fails the "smell test". I expect to refactor this
code, but I'm calling it a night for now.
I believe RIO stands for: "ReaderT <something-something> IO", which is a nod to
the top-level application data type:
```haskell
-- This is a simplification
newtype RIO env a = RIO { runRIO :: ReaderT env a () }
```
I read about RIO from an FP-Complete blog post a few months ago, and now I'm
excited to try it out for a real project. Bon voyage!
As the previous commit mentions, I'm attempting to build and deploy this project
with `nix-shell` and `nix-build` instead of `cabal` and `stack`.
I'm in the Hamburg airport right now, and my internet connection isn't stable
enough to test this, so I'm committing it until I can more robustly test it.
I'd like to see if I can avoid using `cabal` and `stack` and build and deploy
this application using `nix-shell` and `nix-build` only. Let's see how that
goes.
The JWT should match "accounts.google.com" or "https://accounts.google.com". If
it doesn't, we produce a validation error.
TL;DR:
- Group all failed stringOrURI function calls as StringOrURIParseFailure errors
I'm attempting to be an obedient boy and implement this and future features
using TDD.
TL;DR:
- Defined a few tests
- Defined an empty GoogleSignIn module
- Defined a Fixtures module to quickly create JWTs to test
TL;DR:
- Add common dependencies like Servant, Aeson, Warp, Cors
- Define a POST /verify endpoint for our client to hit
- POST to /verify client-side onSignIn
Using Haskell's Text.ParserCombinators.ReadP library for the first time, and I
enjoyed it thoroughly! It's nice avoiding a third-party library like MegaParsec.
Before starting my take-home assignment, the instructions advised me to create a
"Hello, world" program in the language of my choice. Since I'm choosing Haskell,
I created this example as my starter boilerplate.
Many Bollywood movies have excellent acting, excellent directing, excellent
storytelling, but in my opinion, they spoil this with unnecessary musicals
interspersed throughout the films.
Dangal is a notable exception here. Overall, I'd say that this movie is
appropriately rated!
