Hi everyone,
I am new in fortran and i’m trying to get Modern Fortran in VScode to work. Have issue with “Had trouble installing fortls, please install manually”. I guess I downloaded fortls ( and findent for sure). I put path from the console in Language Server Fortran Path fortls box, but it doesn’t gave any result. Still “Had trouble installing fortls, please install manually”. Am I something missing?
Hello everyone,
(I am not English speaking, so I really appologise for possible mistakes).
I’m totally new in Fortran and I try to find an explanation how to run Modern Fortran for VS code. Specifically, I found it, but didn’t understand at all. The main problem for me is the installation of fortls.
I have the following error: “Had trouble installing fortls, please install manually”. At first I saw information that I should specify the correct path, but then I figured out that before troubles with path I should install so called pip, shouldn’t I? If yes, how and where? I tried to download all similar extensions for VS (pip manager, pip installer, Pypi assistant) and then entered “pip install fortls” (and similar commands) in terminal but it clearly didn’t change anything. Also I tried to find it via links, but it’s even more not understandable what I should download and in which order. All guides/forums I read implies that I already know how to download PyPi / pip, but I’m not.
To be honest I even don’t understand why Modern Fortran downloads c++ extension, but uses packages written on Python.
I would very appreciate if someone will explain me what exactly I should do to install fortls and get Modern Fortran to work. I spent already 4+ hours only on this, and don’t have any hope to deal with it on my own. I only had an experience with C# in VS, so all this things with downloading different packages to download different servers and extensions is very hard for me
@seme4ka008 welcome to the forum! I moved both of your posts into the same thread, as it seems to be the same issue.
Hi @seme4ka008, welcome.
Please follow these steps mentioned on the Modern Fortran- VSCode pageModern Fortran- Visual Studio
Here are possible steps, which you should follow (copying text from the page mentioned above):
fortls to be automatically installed with pip or Anaconda and if the location where fortls is installed is not in your PATH point VS Code to the fortls location by setting{
"fortran.fortls.path": "/custom/path/to/fortls"
}
By default, the linter used is gfortran, Intel’s ifort and Intel’s LLVM based compiler ifx are also supported. One can use a different linter compiler via the option
{
"fortran.linter.compiler": "ifx/gfortran"
}
Therefore C/C++ extensions are necessary.
Two formatters are supported findent and fprettify. Both of them can be installed with pip automatically through the extension.
The formatter is controlled by the user option
{
"fortran.formatting.formatter": "findent" | "fprettify" | "Disabled"
}
In nutshell, you need to install ifortls and fprettify/findent though conda or pip.
For fortls:
With
pippip uninstall fortran-language-server
pip install fortls --upgradeor with Anaconda
conda uninstall fortran-language-server
conda install -c conda-forge fortls
for fprettify:
pip install fprettify
conda install -c programfan fprettify
Hope this helps. Good luck!!
Thanks for the reply!
Thank you in advance and sorry for probably silly questions
UPD: I think I’ve got everything except findent/fprettify. I have installed it and put the path from scripts folder to the settings, but VS still cann’t see findent/fprettify and don’t install it (error PIP: Error: spawn pip ENOENT). Do you know what the problem can be?
Ok, thank you!
