Coverting move time to clock time in pgn

[Odd Gunnar Malin]

Is there a program to convert [%emt to [%clk in a pgn file?

I want to export game played in Fritz to Lichess study. Fritz use move time but Lichess can only import clock time.

What I try to do is to play "serious" game against an engine, If there is other GUI that support what I need, let me know. I have Hiarcs, Shredder, Aquarium and Fritz.

My requirements are:
* Playing with Fide timecontrol. e.g. 90 min. in 40 moves the 30 min. to finish the game with 30 se. inc. from move one.
* Using the DGT board
* Save time usage in the game, but not the pve or eval.
* Can use Dragon and Hiarcs as an engine.

Fritz are coming close with onlty using wrong time format.

I will play an "important" tournament in a month and need to play some training games that I share with my coach as Lichess study. One of my problem is time management so it is important to have the time usage in the score.

Rename your input pgn to s1.pgn or revise the code. You may revise the time control see the comment in the code "# TC 90m+30s in 40moves + 30m+30s for the rest of the game." Experiment if adding 30min is at move 40 or 41 by modifying the value in "movenum_addtime = 41".

I tested it in a 3+0 game in chessbase site then convert the game.

Here is a python script to convert emt to clk.

Thanks, I will test it. I'm not too familiar with python but should manage this. By the way Chessbase set the timecontrol as a tag (following the standard with an extra 0/0 in the middle). So it should be doable to get this from the pgn.
But for my use this script is enough. I don't play too many games with 90+30 time control.

Tested it and it worked great with importing Fritz games into Lichess and have the clock showing time used.
One warning, Fritz break lines in the middle of a emt command so this must be fixed manually. There could be added up some small (seconds) difference but this doesn't matter. The important is to see where you are in timetrouble and where you used too much or too little time.

Thanks again, you saved me for some hours with c++ programming.

You can use sed to fix the line breaks. Tested on win10.

1. Create a sed text input file say emt.dat with just the following line:
s/\(\[%emt\)\s*\(.*\]\)/\1 \2/g

2. Run the command:
sed -e "1h;2,$H;$!d;g" -f emt.dat infile.pgn > outfile.pgn

This will put all the emt codes on one line and will work on inputs like

[%emt
xxxx]

with spaces after emt and before xxxx.

This will put all the emt codes on one line and will work on inputs like

[%emt
xxxx]

with spaces after emt and before xxxx.

Thanks, but for my use it is faster to do it manually, it's only one game at the time. I see the error when I do the copy/paste from Fritz. Could though be usefull if someone who want to do it on all their games in one go. You could maybe make a script that run on right click, but then it would be better to put this regex line into the python script. For me I maybe manage ten games in this training month so there is no need for it.

I did only mention it if other will try the script and get an error code when running it.
