FileExistUTF8 problem
lazarus / 68-Other OS

----------------------------------------------------------------------

Hi, i'm currently try to resolve a problem with the function
FileExistUTF8.

In my application i have :

Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i Folder :=
'.' + PathDelim + FileDir + PathDelim;    //    LF := Folder +
'lclstrconsts' + '.' + Language + '.' + C_PoExtension;    if
FileExistsUTF8(LF) then // existe-t-il ?     
Translations.TranslateUnitResourceStrings('LCLStrConsts', LF,Language,
UpperCase(Language)) // on traduit    else     
ShowMessage('FileNotFound : '+LF);      

Note LazUTF8 and LazFileUTils are in uses (not FileUtils)

The FileExistsUTF8 always return me "file not found"

My application work well on Linux Manjaro 64 bit and Windows 10 64 bit

I'm on MacOS High Sierra and Lazarus 1.8.5 32 bit with carbon.

What can i do ?

Thanks

Best regards

use expandfilename to convert the relative path to absolute and see if
that leads to the file you assume it points.

Hi

Expandfilename doing anything. I'm also tried by assigned folder value
in hard like

/Users/usename/Documents/Projets/Lazarus/Components/GIFViewer/demos/gi
fview/languages/

I'm also tried FileExist(UTF8ToAnsi(LF); same issue.

Do you think is related to MacOS High Sierra ?

@BeanzMaster
I tested FileExist/FileExistsUTF8, both works fine on High Sierra.

@GetMem

If i do Code: Pascal  [Select][+][-]window.onload = function(){var x1
= document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i
ExtractFilePath(Application.ExeName) it return

"/Users/usename/Documents/Projets/Lazarus/Components/GIFViewer/demos/g
ifview.app/Contents/MacOS/"

if i do Code: Pascal  [Select][+][-]window.onload = function(){var x1
= document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i
getCurrentDir it returns "/"

So what's the trick under MacOS ?

I did not test with gifviewer, just with a regular file.

"/Users/usename/Documents/Projets/Lazarus/Components/GIFViewer/demos/g
ifview.app/Contents/MacOS/"
Yes because gifview.app(bundle) is basically a directory. When you're
done with the development, you should copy the executable
"gifview"(located in your main development folder) into the
bundle("gifview.app/Contents/MacOS/") and replace the symlink with the
executable. You can achieve this by right clicking gifview.app then
"Show Package Contents". It's common practice(OSX) to keep the
resources(images, language files, etc) inside the bundle, however if
you wish a solution which will work on every major platform you can do
something like this:
Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i var 
PathToLangFiles: String;begin  {$IFDEF LCLcarbon}    PathToLangFiles
:= Copy(Application.ExeName, 1, Pos(ApplicationName + '.app',
Application.ExeName) - 1) + PathDelim + 'languages';  {$ELSE}   
PathToLangFiles := Application.ExeName + PathDelim + 'languages'; 
{$ENDIF}           end;       
The above code will return the languages directory located in the main
development folder, beside the executable(bundle on osx).

Thanks GetMem. Yesterday i see, i enable the gdb output. This is
because i've  enabled "Include Application Informations" in the
project's option.
I had also some problem with GDB and this project du to the symlinks 
and by disable it all gone to the normal.

I'll test your piece of code

Thanks

Cheers

Me to, i have some problem with GDB on some application it work and
sometime not GDB not stop and run continusly in background. Each time
i want recompile lazarus ask me to stop DBG and i need to launch
without debug.

So i resolve my problem with path i'm use Application.Location for Win
and Linux and Code: Pascal  [Select][+][-]window.onload =
function(){var x1 = document.getElementById("main_content_section");
if (x1) { var x = document.getElementsByClassName("geshi");for (var i
= 0; i Copy(Application.ExeName, 1, Pos(ApplicationName + '.app',
Application.ExeName) - 1); for Mac

Thanks again
