LiteStep.net Forums

using LS on a portable device, i don't want to hard-code the paths of the apps, witch are also on that device. however, relitive paths do not seem to work correctly. for example, with

AnApp "..\this\will\not\execute\if\you\try.exe"

in evars.rc and

*Popup "An App" "$AnApp$"

in popup.rc, the app will show in the popup menu, with the correct icon, but will not execute when clicked. using xpopup 2.0.5 and the latest (non-beta) LS core. i have reported this as a bug here. thanks in advance for any help or suggestions.

I think it has to do with the path being relative to a location you don't know. Try doing something like

AnApp ".."

and then

!msgbox $AnApp$

and see if you get a location different than the one you are thinking of.

!alert $AnApp$

with AnApp set as

AnApp ".."

returns an msgbox with "Litestep" as the caption, and

..

as the text. litestep does not autocomplete the directory.

for now, i'm thinking of just using a batch file that will run relitive files based on command-line auguments. hopfully i convince them to impliment it as LSDev though :)

Try doing \ instead of .. and see if it likes that. You could also do $LiteStepDir$programs\anapp.exe

for now, i'm using a batch file

*Popup "$Browsername$" !execute ["Run.bat" "$Browser$"]

with one line in the batch file

%1

works, although it is not ideal. the cmd window pops up, and there is no icon.

as for doing \ instead of .., you'll have to explain what you mean. i don't quite understand.

and yes, i can do it relitive to the litestep dir, but my apps are elsewere, and i have other things pointing to them and would rather not change thier relitive location.

AppName \path\to\executable.exe instead of ..\path\to\executable.exe

relitive to the litestep dir?
i want to go up one dir, to the root of the drive, then run an app from there. is there another way i can find the root of the drive that litestep is on?

\ is the root folder. And have you tried $LiteStepDir$..\this\will\not\execute\if\you\try.exe?

i will try \ later, $Litestepdir$\..\this\will\not\execute\if\you\try.exe does not work.

\path\to\executable.exe does NOT work.

Have you tried doing cmd /c ..\path\to\executable.exe instead of your run.bat?

/C Carries out the command specified by string and then terminates

that works fine at home, with administrator privileges. i will try it at school with much less :)

but the command window still remains open while the app is running, so it's not much help.

@echo off
Start "..." %1

seems to work, at least at home. will try at school.

I can't remember...is there a fork command in windows? Like if you were to do it in Linux you would do something like "command &" and you would get sent back to the prompt and in this case it would close the window. And another weird note...when I run it from console it doesn't show the command window whereas if I do it from !Run it does. Weird!

eh, just m$ messing with your mind.
and i don't think there is a fork command with windows, maybe there is though...

How about a startup script that does "cmd /c "cd $LiteStepDir$ && cd \ && cd > $LiteStepDir$root.rc"? Don't have LS on this machine so I can't test it..but it should work if you ran it from LS since you need the translation of $LiteStepDir$

wait, what would that do?
how do i do that?

what about parsing the $litestepdir$ variable to get the drive letter?
how can i do that?

That will export the drive letter that LS was run from into a file called root.rc. Then you will need to parse it so you can use it.

You have to run the string I gave you from LiteStep. LiteStep is the only thing that understands what $litestepdir$ is and will parse it to whatever folder LS is in. So basically you will need to use mzscript to run it and parse it into an evar.

after an interesting conversation on irc, i came up with the following batch file:

@echo off
SET lsdir=%cd%
cd \
SET root=%cd%
cd %lsdir%
echo Lsd "%root%">drive.rc

it makes a file in the litestepdir (provided it is run from the litestep dir) called drive.rc that sets a variable (Lsd) to the drive letter of the drive LS is run off of.

thanks for your help!

i declare this issue solved. it would still be nice if they stuck .. functionality in the core though.

Note...that only works if you put the bat file in your LS Directory. Put it anywhere else and you get whatever folder you ran it from.

yes.

Using xLabel/Stats? Try this in a command:

!ParseEvars !SetEvar lsd %[between('$LitestepDir$', 1, 3, index)]%

Then check the var...

!alert $lsd$

Does LSLUA support a LEFT() function?

Yup, you could use string.sub(string, start, stop).

AppPath "$LiteStepDir$..\Programs\App\app.exe"

works just fine...

That looks too easy. I prefer more complicated solutions.

xcal:
your solution actually works better for finding the drive letter, since the ".." will go up only as many directories as you tell it to.

bolth usefull solutions, although i have implemented neither :)
still using the batch file, though i will change when i get around to it :)
