Somewhat decent syntax highlighting for IBMi languages such as RPG, CL, DDS, MI, and RPGLE fixed/free.

I made this extension because I do a lot more reading than writing with IBMi languages at work and I always have VS Code open. I also wanted to learn how to make a simple language extension for VS Code and get better with regular expressions.

Pretty much all I did was crawl through various IBM documentation on my lunch breaks and throw some regular expressions in here when I got the chance. The regex I made probably isn't too efficient and it does mess up sometimes, but I think it works for like 90% of cases I've come across.

By all means, I probably got a couple things wrong; submit a pull request or issue if you see something please! (That goes for anything in here)

This extension is really only useful for reading code, not writing. See Issue 50 for more details.

• Syntax highlighting for RPG III and RPG/400 - H,F,E,L,I,C,O specs
• Syntax highlighting for Control Language (CL)
• Syntax highlighting for DDS files - physical, logical, display, printer, and ICF
• Syntax highlighting for some Machine Interface (MI) - see below
• Syntax highlighting for RPGLE fixed - H,F,D,I,C,O,P specs
• Syntax highlighting for RPGLE free
• Syntax highlighting for embedded SQL in SQLRPG and SQLRPGLE
• Support for a mix of RPGLE free and fixed format
• Support for binder language
• Support for DB2 SQL keywords in embedded SQL

If anyone stumbles across this and has any awesome material for machine interface, please send me an email. I really only made the bare basics for MI and I'd love to add to it

For each source type, I lumped legacy(system/38) source types together with the regular source types.

See screenshots/ for more examples of syntax highlighting.

• npm install -g vsce
