The current code is not able to unset an environment variable, only to set it to an empty value. This patch refactors a bit the Message class and uses a new EnvChanger helper class that allows to change temporarily an environment variable and that is able to unset variables if needed.
The patch also adds new functions hasEnv and unsetEnv in environment.cpp.
Open issues:
* there may be systems where unsetenv is not available and putenv("name=") does not do the right thing;
* unsetenv may lead to leaks on some platforms.
* when using unsetenv, we may need to remove strings from the internal map that setEnv uses.
* some functionality is in new modules now
new header locations and library names: QtConcurrent and QtWidgets
* method setResizeMode is renamed to setSectionResizeMode
* deprecated QAbstractItemModel::reset() is dropped now
* platform specific code like QApplication::syncX() is not common anymore
* QString::fromAscii() is dropped now
* some QDesktopServices methods has been moved to QStandardPaths
This patch puts all projects into subfolders (at least for MSVS). In this
way, there is a better overview (especially if the number of test projects
will be increasing).
Next try to make it to work on APPLE (and maybe on WIN32)
a.) Create the needed data-dir at configure time
b.) Use different target names for executable and data created with them
A dummy getGuiMessages function was missing. Instead of adding it everywhere, a new file is created that contains all the dummy functions needed by the tests.
The previous scheme of loading all possible translations and checking
whether the work is a bit too much "brute force" and causes problems
on Mac OS X (documents loaded with the wrong language).
Now there is an helper static method in Messages class that checks
whether a readable .mo file exist for the language. There should be an
API in gettext for doing that, but alas it is not possible.
As a consequence the method Language::translated() has been removed,
along with its cache.
In order to interact with native osx applications, AppleScript support is a plus.
Here is a patch that makes LyX respond to a simple command (run) and that allows to communicate with LyX as with the LyX client.
Example of use:
tell application "LyX" to run "server-get-filename" with argument ""'
returns
message:/Users/bpiwowar/newfile1.lyx, code:0
with a message and the error code
The goal here is to get rid of the old code that modified variables
LANGUAGE and LC_ALL, therefore creating the problems mentionned
in the ticket.
In the new system, there is no explicit "GUI" message handler, that
needs to be reset at each language change. Instead, getGuiMessages
calls getMessages with the correct parameter. This allows to simplify
greatly the code and to remove a lot of old cruft.
