Thomas Fjellstrom said: I do believe that the loaders will load 8 bit bitmaps, but up convert on load (not entirely sure). Yes, they do. If I were to add 8 bit bitmaps to Allegro 5, I would probably make the palette a property of each bitmap (you'd be drawing them to a higher-colour depth display anyway) and do on-the-fly conversions when needed (so you don't get penalised more than once if the palette doesn't change). |

8-bit doesn't necessaily mean palette. I think it would make sense to support something like GL_LUMINANCE in OpenGL ES 2.0: Quote:
Each element is a single luminance value. It could save a lot of texture space for e.g. fonts. Saving texture space reminds me, we should add an example how to use texture compression (OpenGL only - unless someone wants to make an addon which wraps around D3D as well). -- |

Just installed this version. I have a problem with the native filechooser. It freezes the program. I'm on Ubuntu 10.04. |

There were no changes to the native dialogs addon from 4.9.22 Can you get a backtrace by running under gdb?

Hmm, I've never tried getting a backtrace for a program that freezes, only for crashes. How would I go about doing that? Testing ex_native_filechooser. |

When it hangs, press ^C in the gdb window and you will get the usual gdb prompt. You can get a backtrace of all threads with: thread apply all bt

With gdb on unix you hand it the program's pid. With threaded applications you want to run this in gdb: "thread apply all bt full" confusing, but it tells gdb to output a full backtrace for ALL threads. -- |

Can you also post the contents of allegro.log?

I think it will be a bit easier to debug with more logging. Please post the allegro.log again after applying this patch.

I'm not sure what the problem is, but it could be a GTK bug. The implementation was bugging me anyway so I changed it a simpler, message-passing type structure, instead of trying to find the bug.

The native filechooser in A5 returns absolute paths, but I want relative paths. What's the simplest method for removing current directory from the path? I noticed that al_get_current_directory returns a string that must be freed. Why? I would prefer to have freeing that off my hands when I need the cwd. |

On a slightly related note, I don't know if this is a big problem (probably not), but al_get_current_directory returns a path without a trailing / (or \). My colleague wrote some code that turned out to be messing up because he assumed there was going to be a / at the end. So I had to create a temporary string and add the / then add the rest of the path.

Trezker said: The native filechooser in A5 returns absolute paths, but I want relative paths.
Just out of curiosity: why? Quote: What's the simplest method for removing current directory from the path? Probably using al_remove_path_component (by the way, it'd be neat if Acc's markup started recognising A5 functions). EDIT: could someone clarify the distinction between al_join_path() and al_rebase_path()? From the description it seems that they do more or less the same thing, except one modifies the first argument and one modifies the second argument...? The example at al_rebase_path() does what I'd expect al_join_path() to do (which doesn't have an example an dprobably needs it) while I would expect al_rebase_path() to more-or-less allow you to do what the OP wants here. |

I want to save the paths in a level file so they can be loaded no matter where the game is installed. If a file is not under the tree, I'm considering importing it by copying the selected file to a folder where the game would want those files to be. Perhaps I should just get the filename part from the path, prepend expected folder and check file existence. If it's not where it's supposed to be then I copy the file selected in filechooser. |

Yeah, I think we should add an `al_path_make_relative(ALLEGRO_PATH *working, ALLEGRO_PATH *path)` or something along those lines. This would take path, and remove "working"'s path components from "path". Its not that hard to do yourself though. -- |

Trezker said: I noticed that al_get_current_directory returns a string that must be freed. Why? I would prefer to have freeing that off my hands when I need the cwd. That's not how things work in C. Look at this: al_change_directory("blah1"); str1 = al_get_current_directory(); al_change_directory("blah2"); str2 = al_get_current_directory(); printf("%s %s", str1, str2); If you do this in a loop a few 1000 times it would mean a lot of strings which have to be kept... only way around that is to free them. What we could do is have you pass in a buffer and length where the string gets written to though, but that would be awkward as you now have to deal with arbitrary buffer lengths. More annoying than adding a free call I think. Thomas Fjellstrom said: Yeah, I think we should add an `al_path_make_relative(ALLEGRO_PATH *working, ALLEGRO_PATH *path)` or something along those lines. The name would be confusing. For example if I'm in "/home/blah1" then want the relative path to "/home/blah2", I would expect to get "../blah2". -- |

Other A5 functions that return strings don't require the user to free. http://alleg.sourceforge.net/a5docs/refman/path.html#al_path_cstr http://alleg.sourceforge.net/a5docs/refman/utf8.html#al_cstr |

Trezker said: "The returned pointer is valid only until the path is modified in any way, or until the path is destroyed." Thats a bit of a special case, the ALLEGRO_PATH structure stores a cache of the c-string so it doesn't have to keep re-making the full string each time al_path_cstr is called, and thats what it returns. I assume al_cstr is the same. Most times with a current dir string, you wan't to keep it around, not have it disappear just because you changed dirs and called al_current_dir again. -- |
