Dear Anthony, I guess all these problems were related to file/folder permissions in your local "bolprocessor" folder. Each time you load a page, the help file is recompiled. This is taken care of by compile_help($text_help_file,$html_help_file) on top of the" _basic_tasks.php" file. The source is "BP2_help.txt" and the result is "BP2_help.html" containing useful tags. Once you have lodaded a grammar, clich "SHOW HELP ENTRIES" at the bottom right which will hilite reserved tokens and link them to entries on the Help window. Each entry opens its own small window, so you can put side by side explanations on "_volumecont" and "_volume(x)" for instance. I modify "BP2_help.txt" form time to time to adjust the order of entries so that the longest prefix of a word appears at the bottom. So, "_volumecont" appears after its prefix "_volume" and will be first searched for on the grammar line. In BP2.9.8 you needed to type command-question mrk and click on the reserved word… This looks better! Problem with that "sortie" directory is also probably one of write permissions. On top of grammar.php you can see that the output directory is automatically created if it does not exist. Well, I use the "mkdir" system command with no options, instead of PHP's own mkdir(). It might make the difference. Long ago I stopped using PHP mkdir() for a reason I have forgotten. You might face a similar problem when editing a '-mi' file. If you edit "-mi.abc1" it immediately creates a "-mi.abc1_temp" folder at the same level as "-mi.abc1", then writes a text file in that folder containing the code for each prototype, i.e. "a.txt", "a'.txt", "chik.txt" etc. These are the files you will be modifying in separate tabaswhen editing each sound-object prototype. After you finished editing, go back to the tag created by opening "-mi.abc1" and click the "SAVE ‘-mi.abc1’" button. This will take all text files and pack them together as an updated "-mi.abc1". I recommend working on a copy to try this! This makes it possible to edit a large collection of sound-object prototypes, each in its own tag, without rewriting the entire '-mi' file each time you changed a parameter. I checked that saving a prototype after changing parameters maintains its consistency. For instance, if you had a dilation range permitted from 30% to 70% and you click the "Never rescale" option, then these values of dilatio ranges should be erased. I am still working on it to avoid accepting zero values in some places (e.g. Resolution). I will add features clearing garbage each time the interface is used, for instance deleting trace files and these temporary folders used to store sound-object prototypes once they are more than 24 hour old. So, make sure that your environment will authorize PHP to do "rm" commands! I have already fixed a few minor problems while writing this message. ;-) You may write installation instructions so that the interface runs smoothly in a new environment. I have only experience with MAMP Pro. We should also try it on Unix and Windows machines… Bernard Anthony Kozar wrote on 22/07/2020 04:40: > Dear Bernard, > > The interface looks & works great! ^_^ > > After I installed XAMPP for OS X, I followed your setup instructions. > The first time I loaded the interface, I had a bunch of warnings > because it could not open & write to the file php/BP2_help.html.
