Creating Projects
|
||
|
|
-----------------
|
||
|
|
|
||
|
|
Initializing Executable Projects
|
||
|
|
================================
|
||
|
|
|
||
|
|
We can init a new executable project:
|
||
|
|
|
||
|
|
$ dune init proj new_exec_proj
|
||
|
|
Entering directory 'new_exec_proj'
|
||
|
|
Success: initialized project component named new_exec_proj
|
||
|
|
Leaving directory 'new_exec_proj'
|
||
|
|
|
||
|
|
The generated project contains all expected subcomponents:
|
||
|
|
|
||
|
|
$ ls new_exec_proj/**
|
||
|
|
new_exec_proj/dune-project
|
||
|
|
new_exec_proj/new_exec_proj.opam
|
||
|
|
|
||
|
|
new_exec_proj/_build:
|
||
|
|
log
|
||
|
|
|
||
|
|
new_exec_proj/bin:
|
||
|
|
dune
|
||
|
|
main.ml
|
||
|
|
|
||
|
|
new_exec_proj/lib:
|
||
|
|
dune
|
||
|
|
|
||
|
|
new_exec_proj/test:
|
||
|
|
dune
|
||
|
|
test_new_exec_proj.ml
|
||
|
|
|
||
|
|
In particular, the `dune-project` file has the expected content:
|
||
|
|
|
||
|
|
$ cat new_exec_proj/dune-project | sed 's/dune [0-9].[0-9]*/dune $version/g'
|
||
|
|
(lang dune $version)
|
||
|
|
|
||
|
|
(name new_exec_proj)
|
||
|
|
|
||
|
|
(generate_opam_files true)
|
||
|
|
|
||
|
|

|
|
|

|
We can build the project:
|
||
|
|
|
||
|
|
$ dune build --root new_exec_proj
|
||
|
|
Entering directory 'new_exec_proj'
|
||
|
|
Leaving directory 'new_exec_proj'
|
||
|
|
|
||
|
|
And the opam file will be generated as expected
|
||
|
|
|
||
|
|
$ cat new_exec_proj/new_exec_proj.opam | sed 's/"dune"/$dune/' | sed -E 's/3.[0-9]+/3.XX/g'

Hello, World!
|
||
|
|
|
||
|
|
We can build and run the project's tests:
|
||
|
|
|
||
|
|
$ dune exec --root new_exec_proj ./test/test_new_exec_proj.exe
|
||
|
|
Entering directory 'new_exec_proj'
|
||
|
|
Leaving directory 'new_exec_proj'

Initializing Library Projects
|
||
|
|
================================
|
||
|
|
|
||
|
|
We can init a new library project:
|
||
|
|
|
||
|
|
$ dune init proj new_lib_proj --kind lib
|
||
|
|
Entering directory 'new_lib_proj'
|
||
|
|
Success: initialized project component named new_lib_proj
|
||
|
|
Leaving directory 'new_lib_proj'
|
||
|
|
|
||
|
|
The generated project contains all expected subcomponents:
|
||
|
|
|
||
|
|
$ ls new_lib_proj/**
|
||
|
|
new_lib_proj/dune-project
|
||
|
|
new_lib_proj/new_lib_proj.opam
|
||
|
|
|
||
|
|
new_lib_proj/_build:
|
||
|
|
log
|
||
|
|
|
||
|
|
new_lib_proj/lib:
|
||
|
|
dune
|
||
|
|
|
||
|
|
new_lib_proj/test:
|
||
|
|
dune
|
||
|
|
test_new_lib_proj.ml
|
||
|
|
|
||
|
|
In particular, the `dune-project` file has the expected content:
|
||
|
|
|
||
|
|
$ cat new_lib_proj/dune-project | sed 's/dune [0-9].[0-9]*/dune $version/g'
|
||
|
|
(lang dune $version)
|
||
|
|
|
||
|
|
(name new_lib_proj)
|
||
|
|
|
||
|
|
(generate_opam_files true)
|
||
|
|
|
||
|
|

|
||
|
|

|
||

|
||
|
|
(name new_lib_proj)
|
||
|
|
(synopsis "A short synopsis")
|
||
|
|
(description "A longer description")
|
||
|
|

|
||
|

|

|

|

||
|
|
; See the complete stanza docs at https://dune.readthedocs.io/en/stable/reference/dune-project/index.html
|
||
|
|
|
||
|
|
We can build and install the project:
|
||
|
|
|
||
|
|
$ dune build --root new_lib_proj @install
|
||
|
|
Entering directory 'new_lib_proj'
|
||
|
|
Leaving directory 'new_lib_proj'
|
||
|
|
|
||
|
|
And the opam file will be generated as expected
|
||
|
|
|
||
|
|
$ cat new_lib_proj/new_lib_proj.opam
|
||
|
|
# This file is generated by dune, edit dune-project instead
|
||
|
|
opam-version: "2.0"

|

And we we can run the tests:
|
||
|
|
|
||
|
|
$ dune runtest --root new_lib_proj
|
||
|
|
Entering directory 'new_lib_proj'
|
||
|
|
Leaving directory 'new_lib_proj'
|
||
|
|
|

||
|
|
Initializing Projects Using the PATH Argument
|
||
|
|
=============================================
|
||
|
|
|
||
|
|
We can init a project in a specified directory:
|
||
|
|
|
||
|
|
$ dune init proj proj_at_path path/to/project
|
||
|
|
Entering directory 'path/to/project'
|
||
|
|
Success: initialized project component named proj_at_path
|
||
|
|
Leaving directory 'path/to/project'
|
||
|
|
$ test -f path/to/project/dune-project
|
||
|
|
|
||
|
|
A project can be initialized in the current directory (addressing
|
||
|
|
https://github.com/ocaml/dune/issues/9209):
|
||
|
|
|
||
|
|
$ mkdir a-new-dir
|
||
|
|
$ cd a-new-dir
|
||
|
|
$ dune init proj project_in_cwd .
|
||
|
|
Success: initialized project component named project_in_cwd
|
||
|
|
$ test -f dune-project
|
||
|
|
|
||
|
|
Initializing Projects Using Esy
|
||
|
|
===============================
|
||
|
|
|
||
|
|
We can init a project using Esy:
|
||
|
|
|
||
|
|
$ dune init proj new_esy_proj --pkg esy
|
||
|
|
Entering directory 'new_esy_proj'
|
||
|
|
Success: initialized project component named new_esy_proj
|
||
|
|
Leaving directory 'new_esy_proj'
|
||
|
|
|
||
|
|
The `esy` project contains all expected subcomponents:
|
||
|
|
|
||
|
|
$ ls new_esy_proj/**
|
||
|
|
new_esy_proj/dune-project
|
||
|
|
new_esy_proj/package.json
|
||
|
|
|
||
|
|
new_esy_proj/_build:
|
||
|
|
log
|
||
|
|
|
||
|
|
new_esy_proj/bin:
|
||
|
|
dune
|
||
|
|
main.ml
|
||
|
|
|
||
|
|
new_esy_proj/lib:
|
||
|
|
dune
|
||
|
|
|
||
|
|
new_esy_proj/test:
|
||
|
|
dune
|
||
|
|
test_new_esy_proj.ml
|
||
|
|
|
||
|
|
And the `dune-project` file does NOT specify generation of an opam file:
|
||
|
|
|
||
|
|
$ cat new_esy_proj/dune-project | grep "generate_opam_files"
|
||
|
|
(generate_opam_files false)
|
