.SH DESCRIPTION
|
|
.B interpres-decode
|
|
is the toml-test harness adapter in both directions and a TOML validator.
|
|
Without a mode flag it reads one TOML document from standard input and writes
|
|
the toml-test tagged-JSON representation to standard output.
|
|
.B \-encode
|
|
reads a tagged-JSON description from standard input and writes the TOML
|
|
document it describes.
|
|
.B \-validate
|
|
parses each named file, or standard input when none are named, and prints one
|
|
line per invalid document to standard error; a named directory is walked for
|
|
.B .toml
|
|
files, every one validated, and the walk closes with a summary on standard
|
|
error naming the counts. The name
|
|
.B \-
|
|
means standard input.
|
|
.B \-json
|
|
prints plain indented JSON instead of the tagged form.
|
|
.B \-struct
|
|
prints a Go struct definition inferred from the document on standard input.
|
|
.B \-schema
|
|
writes a TOML template for the struct type
|
|
\fITYPE\fR
|
|
declared in the Go source file
|
|
\fIFILE.go\fR,
|
|
taking the key names, comments and defaults from the fields' tags.
|
|
.B \-version
|
|
prints the binary's version and exits.
