Flight Checker

Data Sources

Provides airports with IATA codes, downloaded from https://ourairports.com/data/ (free, public domain)

Need to save as:

• data/airports/airports.csv (8,374,699 bytes, last modified Oct 6, 2019) Large file, containing information on all airports on this site.

• data/airports/countries.csv (20,386 bytes, last modified Oct 6, 2019) A list of the world's countries. You need this spreadsheet to interpret the country codes in the airports and navaids files.

• data/airports/regions.csv (365,815 bytes, last modified Oct 6, 2019) A list of all countries' regions (provinces, states, etc.). You need this spreadsheet to interpret the region codes in the airport file.

Clean Architecture approach

cmd >> framework >> application >> domain

Using mockery

For example, to generate a mock for the Logger interface defined within the pkg/domain directory: ~/go/bin/mockery -dir pkg/domain -name Logger (this creates mocks/Logger.go) (name can also be a comma-separated list of interfaces)

Using sqlite cli

Run sqlite3 ./data/flightchecker.db DDL and DML statements are terminated with ;. Exit using Control-D Useful dot commands:

• .tables => lists all table names
• .schema => lists create statements for all tables
• .schema t => lists create statement for specified table

How to build

• Check the repo out to anywhere outside of $GOROOT
• Install sqlite3 locally
  • e.g. on MacOSX brew install sqlite3
• Install gcc locally
  • e.g. on MacOSX install xcode
• Build the sqlite 3 driver using GCC
  • CGO_ENABLED=1; go install --tags "darwin" github.com/mattn/go-sqlite3
• Set your API Host and Key in arguments.json
• Build the code, doesn't need GCC
  • go build ./...
• Run the flight checker
  • ~/go/bin/flightchecker
• Or run the airport code finder
  • ~/go/bin/airports

Intention of the Go tool is not to need Makefiles!

Run go task ./... where task can be

• clean => removes object files from source dirs, mostly un-needed!
  • e.g. go clean -cache ./... - removes cached unit tests
• list => lists all packages and imported modules
• get => downloads and install code or modules (to the $GOPATH)
  • e.g. go get github.com/sirupsen/logrus (uses latest version) - updates go.mod
• build => compiles all code, but throws away the results
• test => compiles and runs all tests, caches results from unchanged tests (add -cover for coverage stats)
• install => compiles all code, writes them to ~/go/bin
