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

Building doesn't work as the dependency is invalid.

$ dune build

File "dune-project", line 5, characters 10-19:

^^^^^^^^^
|

|
|
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:

$ dune build invalid.opam

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
