In CLI mode, the -R REPO common option is supported. Due to limitations in the argument dispatching code, any -FLAGS must come after the final sub- (or subsub-) command.

The -json-input FILE option can be used to read JSON data and process it like the HTTP interface would. For example:

fossil json -json-input my.json

The commands include:

anonymousPassword
artifact
branch
cap
config
diff
dir
g
login
logout
query
rebuild
report
resultCodes
stat
tag
timeline
user
version (alias: HAI)
whoami
wiki

Run 'fossil json' without any subcommand to see the full list (but be aware that some listed might not yet be fully implemented).
