RFC: Translating Wine's dialogs with PO files
by Francois Gouget 12 Sep '11

12 Sep '11

This is the next step in making full use of the PO files for translating Wine. But how to get there is unclear, hence this RFC. The issue with dialogs is that in RC files all the dialog and control sizes are hardcoded. For instance in the line below '208, 6, 56, 14' represent the x-left, y-top, width and height of the button: DEFPUSHBUTTON "Save As", IDOK, 208, 6, 56, 14, BS_DEFPUSHBUTTON | WS_GROUP | WS_TABSTOP The problem is that once translated to French, for instance, the label becomes 'Enregistrer sous' which is much longer and may require enlarging the button. But RC files do not contain the information needed to do that automatically. For instance they don't specify enlarging this button requires enlarging the 'Cancel' and 'Help' buttons below too. So how do we solve this problem? Option 1 - Automatically layout the dialogs at compile time ----------------------------------------------------------- Gtk applications solve this problem by storing all the information needed to automatically layout dialogs in an XML file. The size and location of all the controls is then computed at runtime, after the dialog has been translated. We could do something similar, it would go something like this: * Use some format that lets us store all the layout information as the primary definition for Wine's dialogs. * At compile time translate the dialogs. * For each translation, layout the dialog and generate an RC file containing the computed control coordinates and sizes. * Then compile the RC files as usual. (alternatively the last two steps could be merged) Questions: * Which format should we use to define the layout? - Glade is the format used by Gtk. However it seems pretty Gtk centric and the set of controls/properties it supports may not match the Windows ones. It's possible to add libraries of custom widgets so that may be a solution. http://en.wikipedia.org/wiki/Glade_Interface_Designer - It looks like Microsoft added support for auto-layout in WPF (Windows Presentation Foundation) for .Net applications. This information can be stored in XAML XML files. http://msdn.microsoft.com/en-us/library/ms750441.aspx https://github.com/yadyn/WPF-Task-Dialog/blob/master/TaskDialog/CommandLink… Does anyone know how this works? Is it something we would need to implement in Wine anyway? Does some project already have support for it? Mono maybe? - For completeness I'll also mention that WxWidget also has a cross-platform layout engine. http://docs.wxwidgets.org/2.9.2/overview_xrc.html However as far as I know, none of them has tools that can generate RC files. * How can we do the layout? - Can we reuse a third-party layout engine? Like the one used for Glade files? - Wouldn't that introduce troublesome build dependencies? - Would it be ok if these dependencies are needed only when in maintainer mode? (In maintainer mode a change to a PO file could trigger an update to the corresponding RC files which would then be committed with the PO file change.) - Should we instead implement it all by ourselves? * How can we mesure the size that strings will take at run time? We probably have all the code we need in Wine. But can we use it are compile time? Will the computed layout depend on the fonts that are installed on the system where Wine is compiled? This is particularly important for languages with non-latin characters such as Japanese, Hebrew or Telugu. Pros: * We would not have to manually layout dialogs ever again. Yay! * We might be able to reuse the graphical dialog design tools of the system we adopt, like Glade or possibly some .Net tools. * There would be no risk of the translation and layout getting out of sync. * We would no longer need one RC file per language, thus eliminating the risk that they become out of sync (e.g. adding a given window style to some but not all languages). Cons: * Just integrating support for the layout engine and generating RC files seems like a lot of work. * Potential for additional build-time third-party dependencies for the layout engine. * Would require rewritting all our dialogs so they have all the needed layout information. That is definitely a lot of work. Option 2 - Add layout information to RC files --------------------------------------------- The idea here is the same as for option 1 except that we would add the layout information as comments in the existing RC files. As a very rough exemple it could look something like this: #layout# start box(orientation = vertical, padding = 8) #layout# start button(expand = true, fill = true) DEFPUSHBUTTON "Save As", IDOK, 208, 6, 56, 14, BS_DEFPUSHBUTTON | WS_GROUP | WS_TABSTOP #layout# end button ... #layout# end box Pros: * Same as for option 1. Cons: * We would be inventing our own syntax. * Not as clean as option 1. * The comments would risk becoming out of sync with the dialogs (e.g. if a developper adds a button but not the comment specifying how it is to be layed out). wrc might be able to check that things are consistent though. * It would be as much work as option 1. * We would have no chance of leveraging an existing layout engine. Option 3 - Use per-language RC files to store hardcoded dialog layouts ---------------------------------------------------------------------- This solution would reuse the existing per-language RC files but would refresh their labels using the PO files. Here is how it would work: * Every control of a given dialog would need to have a unique id. This should only be an issue for static labels which currently tend to all have -1 as their id. So we would first have to reassign them different ids like -1, -2, -3 or stc1, stc2, stc3, etc. * For each control that has a label in a language-specific RC file, look for the corresponding '<dialog-id>+<control-id>' combination in the English RC file. If no match is found that's an error. * Take corresponding English label and use the PO file to translate it. * Use the translated label instead of the, potentially outdated, one that was in the language-specific RC file. * This could be done by wrc when generating a .res file. This way any PO file change would immediately be reflected in the build. Alternatively this could be a maintainer-only task that updates the language-specific RC files whenever a PO file patch is committed. We could even do both so the labels in the language-specific RC files don't become too out of date. * If a given dialog is missing from a language-specific RC file, we would do as if the English dialog data was present instead and proceed as described above. Pros: * The current RC files would not need extensive modifications. * In fact we could progressively simplify them by removing all the translated dialogs that don't change the layout. * This solution feels like it should be easier to put in place than an automatic layout one. Cons: * We would still need to manually layout or verify the layout of every single dialog for every single language :-( * The translators would have no idea that there is a dialog whose layout may need to be changed as a result of their changes to the PO file. Developpers would similarly be hard pressed to make the connection and would likely lack the motivation to update the dialog layouts. So the dialog layouts would likely continue to be rarely updated and possibly incorrect. Exactly like today. * For every dialog with a customized dialog the translations would be stored both in the language-specific RC file and in the PO file. This could be confusing. Option 4 - Put the sizes in special PO files -------------------------------------------- This would really be a very ugly hack. Like option 2 it requires that every control of a given dialog have a unique id. Then for each of them we would create PO file entries of the form: msgctxt "<rc-filename>:<dialog-id>:<control-id>" msgid "<x>:<y>:<width>:<height>" msgstr "" We then put all these 'messages' in a sizes-<lang>.po file. Whenever a control needs to be resized a 'translation' would be provided in the relevant sizes-<lang>.po file. We would only keep the English RC file and when compiling the resources for a given language wrc would check whether the sizes-<lang>.po file contains a translation of the size data for the current control. Pros: * Maybe the easiest solution to put in place. Cons: * Totally ugly. * Probably awful to work with to change the layout of a dialog. * All the drawbacks of Option 2. -- Francois Gouget <fgouget(a)free.fr> http://fgouget.free.fr/ f u kn rd ts, ur wy 2 gky 4 ur wn gd.

I'm willing to update winedev guide, but I'd like more info first. I found that --file accepts the set of commands to execute (but winedbg exits afterwards), but what does --command do? Is there a way to specify initial commands to execute, then stay *inside* winedbg after the last command of the file is issued? Frédéric

Support for alternate data streams in NtCreateFile?
by Frédéric Delanoy 12 Sep '11

12 Sep '11

Hi, What is the support status of (NTFS) names streams in wine? I only see include/winnt.h:4788:#define FILE_NAMED_STREAMS 0x00040000 but it doesn't seem to be used anywhere else in the code. (there's probably no possible translation in most filesystems) NtCreateFile (hence cmd) currently happily creates files/directories with colons in them, while it probably shouldn't for most FS. I'm asking this because ':' is normally disallowed in file/dirnames (http://msdn.microsoft.com/en-us/library/aa365247(v=VS.85).aspx), and was trying to add tests in ntdll/tests/file.c, except when named streams are supported by the underlying FS. Should I test the flags returned from GetVolumeInformation, and add tests for both named-stream-allowed and non-named-stream allowed FSs? Or should I assume that named streams won't ever be implemented and assume colons are disallowed, without checking the FILE_NAMED_STREAMS flag? Frédéric
