Debugging

By default, the revel run command without a run_mode defaults to dev.

Hot Reload

As part of the development cycle, Revel can be configured to ‘watch’ for local file changes, and recompile as necessary.

• See the watchers in conf/appconf

Testing Module

Revel comes with a test suite, see the Testing Module

Debug using gdb

Go applications can be debugged using the GNU Debugger (GDB).

Intellij debugging (goland)

1. Create your project, for this example i will be using canonical “revel new github.com/myaccount/my-app”
2. “revel run github.com/myaccount/my-app” to generate tmp/main.go - this file is needed by intellij
3. Shutdown the running server
4. Create project in intellij from existing sources
5. Create run configuration and in “Program arguments” add “-importPath github.com\myaccount\my-app -srcPath \src -runMode dev"
6. Point “File” to <your gopath>\src\github.com\myaccount\my-app\app\tmp\main.go
7. In “before launch” add “Run external tool”. There: Program: <your gopath>\bin\revel.exe Paramerets: build github.com/myaccount/my-app
