Ocaml on Atom


#1

Hi every one!

I followed this guide for install ocaml on atom (https://github.com/the-lambda-church/merlin/wiki/atom-from-scratch), i have with S.O Linux Debian 8.5.
My problem is that, atom don compile the ocaml code, because the path that i use for merlin and nuclide is wrong.
Could you tell me how i can find the correct path?


#2

What is the path you’re using? Where is Merlin installed?


#3

i use this path ~/.opam/4.02.1/share/merlin.

I can’t understand where is merlin, i have install merlin following the guide but i dont understand where is exactly.


#4

If apm install ocaml-merlin is a stand-alone package, then the Merlin executable would be in your .atom/packages/ocaml-merlin directory.


#5

when i put this path on merlin, i see this error on atom:
Uncaught Error: spawn EACCESinternal/child_process.js:302Show Stack TraceThe error was thrown from the ocaml-merlin package. This issue has already been reported.


#6

What happens if you restart Atom?


#7

nothing, it is the same of when i wrote the post.


#8

Under View -> Developer -> Toggle Dev Tools, you can get to the JavaScript console within Atom and see the full text of the error. Please post it here.

To make it easier to read, please wrap the error message in backticks as described here.


#9

Sorry for the error, but is the first time that i work with atom an ocaml.

error with command: swift Array[3] Object error: Error: spawn swift ENOENT*

#10

That’s not the same error. What’s the text of the EACCESS error?


#11

Okay, I’m going to ask the same question I did earlier, but more directly. Is there an executable file in .atom/packages/ocaml-merlin? Because the error you’re seeing would be more consistent with the package requiring you to install Merlin separately. If there’s no executable in that directory, then you need to install Merlin.


#13

I dont know how is the executable extension on linux, but in the directory there are:
coffeelint.json lib node_modules README.md
keymaps LICENSE.md package.json styles


#14

It’s usually nothing at all. What’s in lib/?


#15

buffer.coffee merlin.coffee selection-view.coffee
main.coffee rename-view.coffee type-view.coffee


#16

Yes, you need to install Merlin.


#18

i tried to install but:

diaccio@DESKTOP-5ACN8J9:~/.atom/packages/ocaml-merlin/lib$ opam
install merlin[NOTE] Package merlin is already installed (current version is 2.3.1).
diaccio@DESKTOP-5ACN8J9:~/.atom/packages/ocaml-merlin/lib$  install merlin
install: manca l'operando per il file di destinazione dopo "merlin"
Try 'install --help' for more information.
diaccio@DESKTOP-5ACN8J9:~/.atom/packages/ocaml-merlin/lib$

#19

In that case, go find where Merlin is.


#20

It was one week that i try to do this, i install 5 time atom and i was the same problem with merlin :frowning:
