md-highlighter README
md-highlighter is a simple extension to highlight files about molecular modeling and molecular dynamics simulation. Specially, it supports NAMD/CHARMM and some of Amber file formats.
Features
Supported format:
- NAMD: rtf, pdb, prm, psf, str, inp
- Amber: in, prmtop, inpcrd, prepin, frcmod
- Gromacs: gro, atp, rtp, mtp (pmx), ...
- small molecule: sdf, mol2 (modified from gromacs helper), ...
- PLUMED: .plumed.dat
- upcoming: (AmberTools leap), lib,...
For gromacs-related files, please install gromacs-helper . For VMD, install TCL . For Gaussian, install Gaussian Input File (gjf) . But maybe I'll make my own syntaxes.
Tested in theme "Atom One Light".
This extension is created with the help of ChatGPT and New Bing.

Conventions
- variable.other.residue-number (except psf,gro)
- entity.name.type.residue-name
- constant.numeric.atom-number (except gro,lib)
- entity.name.tag.atom-name
- support.type.atom-type
- constant.numeric.mass
- constant.numeric.coordinate
- string.quoted.charge (rtf,psf,mol2,prepi, except rtf)
- string.quoted.element-symbol
- string.quoted.bond-number
- string.quoted.velocity
- support.type.segment-name (except psf)
- entity.name.function: a different kind of blue
But different file types might rendered with different colors...
Known Issues
- Are the files too colorful?
- PDB: CONNECT and TER highlight later terms
- RTF: the structure depiction after ! is italic...
- atom names
- with
' , + , - in them are matched by \\S+ but not [A-Z+-']
- not always start with numbers (
-?\\+?[A-Z]+[0-9]*[A-Z0-9_]* )
- MTP: the last word in rotations
- Amber .in files include various types; so do Gromacs .itp file
- PRMTOP: E-01, normal
constant ?
- FRCMOD: I know atomtypes can only be 1/2 characters long. Matching with this may solve the mismatching problem
- LIB: later section not read and implemented
- MTP/RTP: cannot match the last atom name?
- not fully tested files for OPLS series and more force field, where naming conventions might be different
TODO:
- add self-defined colors for aminoacids types (polar, nonpolar, etc.)
- add self-defined colors like pink, etc.
- sdf file?
