THIS REPO IS FACING A COMPLETE OVERHAUL/REVAMP/RENOVATION IN ORDER TO SUPPORT .NET6.
Unfinished tasks so far:
FSX is the ideal tool for people that use F# for their scripting needs.
The best way to describe it is to start first with some questions:
These are the main annoyances when working with F# scripting. Granted, F#+FSI is already much better than the alternatives (as many more errors are thrown much earlier than at runtime, and as strongly-typed functional languages are generally faster). However, we can do better.
To the above three questions we could even follow-up with new ones:
FSX answers all of these latter questions with a categorical YES!
The creation of FSX was inspired by several facts:
#!/usr/bin/env fsharpi --warnaserror
as the flag gets ignored). Note that using fsx in shebang, however, will treat warnings as errors.echo $'#!/usr/bin/env fsharpi\nSystem.Threading.Thread.Sleep(999999999)'>testfsi.fsx
echo $'#!/usr/bin/env fsx\nSystem.Threading.Thread.Sleep(999999999)'>testfsx.fsx
chmod u+x test*.fsx
nohup ./testfsi.fsx >/dev/null 2>&1 &
nohup ./testfsx.fsx >/dev/null 2>&1 &
ps aux | grep testfs
In my machine, the above prints:
andres 23596 16.6 0.9 254504 148268 pts/24 Sl 03:38 0:01 cli /usr/lib/cli/fsharp/fsi.exe --exename:fsharpi ./testfsi.fsx
andres 23600 0.0 0.0 129332 15936 pts/24 Sl 03:38 0:00 mono bin/./testfsx.fsx.exe
Which is a huge difference in memory footprint.
In Linux/macOS, the old-fashioned way by cloning and compiling it yourself:
./configure.sh --prefix=/usr/local
make
sudo make install
(If you're using Windows, just build with "make.bat" and install with "make install".)
After installing, you can already use the #!/usr/bin/env fsx
shebang in your scripts.
If you want to use fsx without having to change the shebang of all your scripts, just
run fsx yourscript.fsx
every time.
For your CI needs (to compile all scripts in your repo without executing them), you could call fsxc
using find
in your CI step.
An example of how to do this with GitHub Actions, is this YML fragment that you could add to your workflow existing in your .github/workflows/
folder:
- name: compile F# scripts
shell: bash
run: |
dotnet new tool-manifest
dotnet tool install fsxc
find . -type f -name "*.fsx" | xargs -t -I {} dotnet fsxc {}
