Please use full_bin instead of cmd, like:

full_bin = "MONGODB_HOST=127.0.0.1:27017 MONGODB_USER=test MONGODB_PASSWORD=test REDIS_ADDR=127.0.0.1 GIN_MODE=debug go run *.go"

Please use full_bin instead of cmd, like:

full_bin = "MONGODB_HOST=127.0.0.1:27017 MONGODB_USER=test MONGODB_PASSWORD=test REDIS_ADDR=127.0.0.1 GIN_MODE=debug go run *.go"

I try this, but in the code I can not get the environment MONGODB_HOST=127.0.0.1:27017 MONGODB_USER=test MONGODB_PASSWORD=test REDIS_ADDR=127.0.0.1 GIN_MODE=debug, and then I have a failure with mongodb init error.

Another option is to use godotenv:

// This would automatically load/inject environment variables from a .env file
import _ "github.com/joho/godotenv/autoload"

[andodeki]

how can I load an env file to be used with the binary??

[slaveofcode]

I could make the binary works without env library (godotenv) by adding ; <your command> at the the bin part

because my env is placed at .env file, so in my case it would like this

[build]
  bin = ";export $(grep -v '^#' .env | xargs); ./tmp/main"
  cmd = "go build -o ./tmp/main ."

With your case, it might look like this. (full_bin removed)

[build]
  bin = ";MONGODB_HOST=127.0.0.1:27017 MONGODB_USER=test MONGODB_PASSWORD=test REDIS_ADDR=127.0.0.1 GIN_MODE=debug ./tmp/main"
  cmd = "go build -o ./tmp/main ."

[rwngallego]

It actually works well with full_bin like:

[build]
  cmd = "go build -o ./tmp/main ./cmd/myapp/"
  full_bin = "DEBUG_ENABLED=true ./tmp/main"

I imagine if full_bin is present then bin is not taken into account, which is fine.

I think this issue could be closed, the answer provided by @slaveofcode solves the problem.

[frankgreco]

This does not work for me

root = "."
testdata_dir = "testdata"
tmp_dir = "tmp"

[build]
  full_bin = "REDIS_PASSWORD=<redacted> go run ./..."
  delay = 1000
  exclude_dir = []
  exclude_file = [".air.toml", ".gitignore"]
  exclude_regex = ["_test.go"]
  exclude_unchanged = false
  follow_symlink = false
  include_dir = []
  include_ext = []
  kill_delay = 2000
  log = "build-errors.log"
  send_interrupt = true
  stop_on_error = true

[color]
  app = ""
  build = "yellow"
  main = "magenta"
  runner = "green"
  watcher = "cyan"

[log]
  time = false

[misc]
  clean_on_exit = false

  clear_on_rebuild = false
