Replacing the DOS Shell

[alin.elena]

Hi,


I have got zeus 3.96m (trial) and I wanted to replace the DOS shell. (cmd.exe whith powershell (the new msh)).
http://www.microsoft.com/technet/script ... load2.mspx

I used COMSPEC variable to set it.
As OS I use vista enterprise

Now the problems
1. Tools->DOS Shell dies immediately after lunch
I have digged and the problem is the /k option. necessary for dos but not for msh.

2. xtags
with powershell as shell xtags will not run.
The error is "Unexpected Error Spawning xTags Executable"
I have checked and xtags is in the path.
I have suspected something wrong with the installation and I have tested xtags by hand
If I run the command in powershell
PS C:\Users\Alin M Elena\testZeus> xtags --c-types=+fp --excmd=p --fields=+afmikKlnsSz --sort=no -f test.f90.tag test.f90
xtags.exe: Warning: invalid character range
xtags.exe: Warning: invalid character range
xtags.exe: Warning: invalid character range
xtags.exe: Warning: invalid character range
xtags.exe: Warning: invalid character range
xtags.exe: Unknown option: --

are there any other variables to set other than PATH? LIB etc?

3. Should I be worried that xtags uses --c-types on a fortran file?

Hi Alin,

1. Tools->DOS Shell dies immediately after lunch I have digged and the problem is the /k option. necessary for dos but not for msh.

I will fix this so the /k option is only used for the cmd.exe command processor

2. xtags with powershell as shell xtags will not run.

The xtags.exe is running being run via the cmd.exe command processor and this might be why it is not running

But it should be possible to change Zeus to run the xtags.exe directly which might fix the problem

Are there any other variables to set other than PATH? LIB etc?

I don't think you even need to set these. Zeus will find always find xtags.exe since it looks in the Zeus install directory

If I run the command in powershell
PS C:\Users\Alin M Elena\testZeus>xtags --c-types=+fp --excmd=p --fields=+afmikKlnsSz --sort=no -f test.f90.tag test.f90
xtags.exe: Warning: invalid character range
xtags.exe: Warning: invalid character range
xtags.exe: Warning: invalid character range
xtags.exe: Warning: invalid character range
xtags.exe: Warning: invalid character range
xtags.exe: Unknown option: --

What the test.f90.tag tags file create

I'm not sure why these invalid character range and unknown option messages are getting generated since these are just ctags command line options, for example:

Code: Select all

C:\Users\Alin M Elena\testZeus>xtags -?

In the Zeus install directory there is an xtags.ini file. You can edit this file to change the xtags.exe command line

3. Should I be worried that xtags uses --c-types on a fortran file?

Probably not. This option is described by ctags as follows:

--<LANG>-kinds=[+|-]kinds
Enable/disable tag kinds for language <LANG>.

So it will only ever be triggered for C files.

Hi Jussi,

What the test.f90.tag tags file create

No

if i run

Code: Select all

xtags  -N -u -f test.f90.tag test.f90

the file gets created
it seems that it does not like --options

I have checked and the warning appears in cmd.exe, too but not the error.

Hi Jussi,

it seems that the parameters get passed in a strange way to the program in msh

Code: Select all

./ctags --c-types=+fp --excmd=p --fields=+afmikKlnsSz --sort=no -f test.f90.tag test.f90

arg 0 C:\Users\Alin M Elena\ctags\ctags.exe
arg 1 c-types=+fp
arg 2 --
arg 3 excmd=p
arg 4 --
arg 5 fields=+afmikKlnsSz
arg 6 --
arg 7 sort=no
arg 8 -f
arg 9 test.f90.tag
arg 10 test.f90

the solution to the problem is to quote each parameter.
so xtags.ini becomes

Code: Select all

[xTags]
Arguments=\"--c-types=+fp\" \"--excmd=p\" \"--fields=+afmikKlnsSz\" \"--sort=no\"

from

Code: Select all

[xTags]
Arguments=--c-types=+fp --excmd=p --fields=+afmikKlnsSz --sort=no

I have tracked down this warning message:

xtags.exe: Warning: invalid character range

It is generated by ctags.exe itself and is caused by a bad regular expression in the PHP parser.
