My FOSS

I finally stop running as administrator.

Thank you, FOSS!

As a way to give back to the FOSS community, I have created and maintained a Copr repository for scientific packages, coprs/thangckt/foss, to keep up-to-date builds of various cutting-edge packages for the latest RedHat based distros.

The repository includes even essential daily-use packages, such as mail client, office stuff, to critical scientific applications like Ovito, Zotero, VScodium, SSH client, and many others.

To install the packages, simply enable the Copr repository:

sudo dnf copr enable thangckt/foss
sudo dnf install ovito zotero  # or other packages

Or add repo file:

sudo dnf config-manager addrepo --overwrite --from-repofile=https://copr.fedorainfracloud.org/coprs/thangckt/foss/repo/fedora-44/thangckt-thang_foss-fedora-44.repo
sudo dnf install ovito

Some available packages:

vscodium	Open-source build of Visual Studio Code
zed	High-performance, multiplayer code editor built with Rust

VSCode extension for LAMMPS script

LAMMPS Script Syntax

A minimal VSCode extension concisely for highlighting LAMMPS input files.

This extension is originally derived from lammps_vscode, which strips off uncommon features to minimizes memory usage and dependencies.

I made it to fit my personal usage and resources. If you need more features, I recommend to use the original one.

Features

• Highlight the keywords in LAMMPS input files.
• Recognizes *.lmp, *.lmps, *.lammps, and in.* files as LAMMPS input files.
• Folding possible between Markers #[ and #]

Extension Settings

• lammps.AutoComplete.Setting: Controls the behaviour of the autocompletion feature. This setting may influence the performance of the extension.
• lammps.Hover.Detail: Control the length of the displayed description in the hover popup.
• lammps.Hover.Enabled: Display command information in a popup when hovering over a command or keyword.
• lammps.Hover.Examples: Display example usage in the hover popup.

Usage

• Run alignment from the editor context menu.
• Support aligning multiple line selections and cursors simultaneously.

Extension Settings

• align.regex.templates: Templates for regular expressions used for alignment. The default built-in templates are:

  {
      "align.regex.templates": {
          "Multiple signs": "=|,|:",
          "Trailing comments #": "(?<=\\S.*)\\s+#",
          "Trailing comments //": "(?<=\\S.*)\\s+//",
          "Trailing comments %": "(?<=\\S.*)\\s+%",
      }
  }
