name=NAME
- filename or hash as a query parameter
filename=NAME
- alternative spelling for "name="
fn=NAME
- alternative spelling for "name="
ci=VERSION
- The specific check-in to use with "name=" to identify the file.
txt

hash
- Output only the hash of the artifact

The /artifact page show the complete content of a file identified by HASH. The /whatis page shows only a description of how the artifact is used. The /file page shows the most recent version of the file or directory called NAME, or a list of the top-level directory if NAME is omitted.

For /artifact and /whatis, the name= query parameter can refer to either the name of a file, or an artifact hash. If the ci= query parameter is also present, then name= must refer to a file name. If ci= is omitted, then the hash interpretation is preferred but if name= cannot be understood as a hash, a default "tip" value is used for ci=.

For /file, name= can only be interpreted as a filename. As before, a default value of "tip" is used for ci= if ci= is omitted.
