move-wrap remover utility for pgn files

[Norm Pollock]

I wrote a utility to remove "move-wrap" from a pgn file. Move-wrapping is where a move starts on one line and continues onto the next line. It is very annoying to read.

It is available temporarily at

http://www.hoflink.com/~npollock/slim.rar

Usage is in a command window on a "clean" pgn file (no comments, no nags, no variations)

example: slim alpha.pgn

This produces "ourR.pgn" without affecting alpha.pgn.

"ourR.pgn" has 5 full moves per line. No move-wrapping. Lines are little shorter. The overall effect is that the pgns are easier for a human to read. Computer programs will not be affected.

Hi Norm,

'Slim' now available from my homepage.

Thanks for another very useful little utility.

Jim.

Jim.

Thanks Jim.

I've taken Slim off my temporary site, so if anyone wants to download it, just go to Jim's site at

http://homepages.tesco.net/henry.ablett/jims.html

In its place, I put up a program that is an alternative to Slim. I call it Trim because I don't want to get confused with Slim2 etc. I would appreciate any feedback as to which is preferable- slim or trim.

The download link is

www.hoflink.com/~npollock/trim.exe

What Trim does is fit as many full moves as possible into a line, without resorting to move-wrap (word-wrap of moves). You can also set Trim to the desired output width. The default is 75 characters (which includes a space after the last token, so if you count you would only count 74). You can set the width to any value from 50 to 100.

The output file is also called "outR.pgn"

Here is the usage (no readme included- see the slim readme.txt for information how to "clean" a pgn file)

trim alpha.pgn

(note: alpha.pgn has to be "clean" of comments, nags, variations)

or

trim alpha.pgn 60

The latter sets the width to 60 characters (including a space at the end).

Hi Norm ,


Trim has a clone PGN-Extract by David J. Barnes


"Output Line Length (-w)

The -w flag allows an approximate line width to be set for output. The
default value is 75 characters. The following request output lines to be
approximately 100 characters wide:

pgn-extract -w100 file.pgn"

Hi Salvo,

pgn-extract is one of my favorite programs. It is my understanding that pgn-extract does not remove "move-wrap" which trim does. Adjusting width is just an add-on for trim and no doubt other programs can do that too.

Speaking of pgn-extract, it is a necessary assistant to trim.exe.

First of all, it can remove comments, nags and variations, which is necessary for trim to work properly.

Second, it can remove a very common "bug" within pgn files. It can do so by using the same command line.

pgn-extract -C -V -N -s %1 -oout.pgn

The program "Scid" for example, creates pgn files with the following "bug": Scid fails to put a space (" ") after the period (".") that follows the move number in a pgn of a game. This is a violation of pgn specs. This bug causes trim to malfunction. However pgn-extract removes the bug by putting in the required "space", and thereafter trim works fine.

Hi Norm,

Sorry, I miss the "move-wrap" word

Can You give me an example?
