issue with pflag flagset
My understanding is that you can use pflag as a drop in replacement of the standard lib's flag (import flag "github.com/spf13/pflag"). So it can be used as a standalone lib I suppose.
-
Which packages do you recommend for building cli tools?
I realy enjoyed the patched version from spf13 with "--" support https://github.com/spf13/pflag

Define custom command-line flag types in Go 1.19
Nice, but Cobra (with pflag underneath) is so, so better.
-
-h --help -help help --? -? ????
Not by default on stdlib. There are libraries available though - https://github.com/spf13/pflag

Coral, a friendly Cobra fork with nearly all its features, but only 4 dependencies
Flag functionality is provided by the pflag library, a fork of the flag standard library which maintains the same interface while adding POSIX compliance.
-
xflags: An approach to command line flags with support for subcommands, positional args, environment variables, etc.
How does it compare to https://github.com/spf13/pflag ?
-
The flag package: strange but good?
spf13 has a drop in pflag that does the - short and -- long flags.
-
What are your favorite packages to use?
oklog/ulid to generate IDs. coreos/go-oidc for validating JWTs I get from auth. google/go-cmp for comparing structs in tests (unless the project is already using Testify). spf13/pflag because life's too short for Go's flag handling. getkin/kin-openapi for validating reqests/responses against my OpenAPI spec (in tests).

akamensky/argparse: Argparse for Golang. Just because "flag" sucks!
What are the benefits of this package over the widely used spf13/pflag?
-
Go’s highly modular nature makes it particularly good for situations where requirements are changing or evolving.

Autenticação com Golang e AWS Cognito
Primeiro vamos carregar nossas envs com o pacote godotenv, depois iniciamos nosso cognito client, passando o COGNITO_CLIENT_ID, que pegamos anteriormente, depois iniciamos o gin e criamos um server, isso é o suficiente.

Tools besides Go for a newbie
IDE: use whatever make you productive. I personally use vscode. VCS: git, as golang communities use github heavily as base for many libraries. AFAIK Linter: use staticcheck for linting as it looks like mostly used linting tool in go, supported by many also. In Vscode it will be recommended once you install go plugin. Libraries/Framework: actually the standard libraries already included many things you need, decent enough for your day-to-day development cycles(e.g. `net/http`). But here are things for extra: - Struct fields validator: validator - Http server lib: chi router , httprouter , fasthttp (for non standard http implementations, but fast) - Web Framework: echo , gin , fiber , beego , etc - Http client lib: most already covered by stdlib(net/http), so you rarely need extra lib for this, but if you really need some are: resty - CLI: cobra - Config: godotenv , viper - DB Drivers: sqlx , postgre , sqlite , mysql - nosql: redis , mongodb , elasticsearch - ORM: gorm , entgo , sqlc(codegen) - JS Transpiler: gopherjs - GUI: fyne - grpc: grpc - logging: zerolog - test: testify , gomock , dockertest - and many others you can find here

Reading Environment Variable from a .env file on a Server
In his code it is done using https://github.com/joho/godotenv
- Libraries you use most of your projects?
-
Restful API with Golang practical approach
envconfig: Library for managing configuration data from environment variables (https://github.com/joho/godotenv)
-
Is this clear why its useful?
There is already a more complete, safer and neatly written godotenv alternative. It may be taken as an educational inspiration for next attempts.

I need some help setting up variables for the sake of my sanity
Chances are you are going to set them in you real server, and most likely you will going to use Linux for that. So for local development create a .env file with those in there. And at the start of you program, load them. You can use https://github.com/joho/godotenv Don’t share that file of course, and don’t put it in git.
