Invalid package names are reported by Dune.
|
|
We also give a hint for common invalid versions such as foo.1.2.3,
|
|
which can result from a users false assumption from opam.
|
|
|
|
$ cat > dune-project <<EOF
|
|
> (lang dune 3.13)
|
|
> (package
|
|
> (name invalid)
|
|
> (allow_empty)
|
|
> (depends foo.1.2.3))
|
|
> EOF
|

|
|
Building doesn't work as the dependency is invalid.
|
|
|
|
$ dune build
|
|
File "dune-project", line 5, characters 10-19:
|
|
5 | (depends foo.1.2.3))
|
|
^^^^^^^^^
|
|
Error: "foo.1.2.3" is an invalid package dependency.
|
|
Package names can contain letters, numbers, '-', '_' and '+', and need to
|
|
contain at least a letter.
|
|
Hint: (foo (= 1.2.3)) would be a correct package dependency

We can take this further and add some really invalid characters into the name:
|
|
|
|
$ cat > dune-project <<EOF
|
|
> (lang dune 3.13)
|
|
> (package
|
|
> (name invalid)
|
|
> (allow_empty)
|
|
> (depends f{oo."1.2.3"))
|
|
> (generate_opam_files true)
|
|
> EOF
|
|
|
|
$ dune build invalid.opam
|
|
File "dune-project", line 5, characters 10-15:
|
|
5 | (depends f{oo."1.2.3"))
|
|
^^^^^
|
|
Error: "f{oo." is an invalid package dependency.
|
|
Package names can contain letters, numbers, '-', '_' and '+', and need to
|
|
contain at least a letter.
|
|
Hint: f_oo_ would be a correct package dependency
