To build aretext, you will first need to install go.

Next, install development tools:

make install-devtools

To build aretext, format code, and run tests:

make

To only run tests:

make test

To format Go and Markdown files:

make fmt

Some files in the project are created by go generate and checked into the git repository. This includes the state machine compiled from commands in input/commands.go. If you add a new command there, you should regenerate the state machine by running:

make generate

Please see the Makefile for all available targets.

You can tell aretext to log debug information to a file like this:

aretext -log debug.log

You can then tail the log file in a separate terminal session to see what aretext is doing:

tail -f debug.log

First, you will need to install dlv.

Then build aretext with debug symbols:

make build-debug

You can then start aretext and attach a debugger:

# Start aretext in one terminal.
./aretext

# Switch to another terminal and attach a debugger.
# If there are multiple aretext processes running,
# replace `pgrep aretext` with the exact process ID.
dlv attach `pgrep aretext`

You can tell aretext to profile its CPU usage like this:

aretext -cpuprofile cpu.prof

This will create a pprof profile that you can analyze using go tool pprof cpu.prof
