---+ Editing iSeries source members with the Vim text editor
%TOC%

---++ Why Vim

Because I like it :) Back when I used Windows I used the excellent [[http://www.textpad.com][TextPad]] editor, but it didn't work very well under [[http://www.winehq.org][Wine]], and is GUI based. I wanted an editor equally at home in a console and on the desktop. Vim seemed easier to understand than Emacs, and I've stuck with it since then. I used to use remote command on the AS/400 to send a text version of source members to !TextPad for editing, and swapped the technique to use Vim on Linux. If you're interested in the programs & commands I use to do this, let [[%MAINWEB%.MartinRowe][me]] know and I'll see if I can get them suitable for download. Using Vim in diff mode with two source members is far easier than SEU's split screen :) And speaking of merging changes, [[http://meld.sourceforge.net/][Meld]] is excellent too, btw. 

---++ Getting Vim

You can download [[http://www.vim.org][Vim]] for just about every computing platform (except native iSeries!)

---++ Syntax checking 

Although Vim comes with syntax files for dozens of languages, RPG and friends aren't among them. I started work on one for RPG, didn't get very far and asked on-line for help. I was given a template to work with from someone on the vim-users list, and got a bit further, but still not much use :( I was then contacted by another Linux user and RPG programmer, Marc Mims, and (with mainly his code) we got a basic syntax file together. Once I understood the technique I expanded on that, and created files for DDS and RPGLE (RPGIV, not free-format). The REXX syntax file works very well for CL code, so I adapted that to work with common CL commands. 

A little while later [[http://www.scottklement.com/][Scott Klement]] started a [[http://archive.midrange.com/rpg400-l/200207/msg00475.html][thread]] on the [[http://lists.midrange.com/mailman/listinfo/rpg400-l][RPG400-L]] mailing list over at [[http://www.midrange.com][Midrange.com]] site. We swapped syntax files though in the end we stuck with our originals. I've continued to tweak the syntax files, but haven't spent much time on them in the last year or so.

---++ Recognising iSeries code files

My download routine appends the member type as the file extension, so that's what I use to trigger the correct syntax file in Vim. I have a =~/.vim/filetype.vim= file with these lines:
<verbatim>
" my filetype file
augroup filetypedetect
  au! BufRead,BufNewFile *.rpg          setfiletype rpg
  au! BufRead,BufNewFile *.rpgle        setfiletype rpgle
  au! BufRead,BufNewFile *.clp          setfiletype clp
  au! BufRead,BufNewFile *.dspf         setfiletype dds
  au! BufRead,BufNewFile *.prtf         setfiletype dds
  au! BufRead,BufNewFile *.pf           setfiletype dds
  au! BufRead,BufNewFile *.lf           setfiletype dds
augroup END
</verbatim>
and =~/.vim/mysyntax.vim= to load those filetypes
<verbatim>
au! Syntax rpg          so ~/.vim/rpg.vim
au! Syntax rpgle        so ~/.vim/rpgle.vim
au! Syntax clp          so ~/.vim/clp.vim
au! Syntax dds          so ~/.vim/dds.vim
</verbatim>
and these lines in my =~/.vimrc=
<verbatim>
syntax on
set filetype=on
so ~/.vim/mysyntax.vim
</verbatim>

See below for the syntax files.


   * [[%ATTACHURL%/clp.vim][clp.vim]]: CLP syntax file for Vim

   * [[%ATTACHURL%/dds.vim][dds.vim]]: DDS (DSPF, PRTF, PF, LF) syntax file for Vim

   * [[%ATTACHURL%/rpg.vim][rpg.vim]]: RPG (RPG400) syntax file for Vim

   * [[%ATTACHURL%/rpgle.vim][rpgle.vim]]: RPGLE (RPGIV) syntax file for Vim
