Hi there,
I have some problems with gretl (snapshop on windows 8) automatically
adding its 'shelldir' to a file path:
<hansl>
eval shelldir
open abdata.gdt
list xList = YEAR IND CAP
store "testme.csv" --csv xList # writes file in
'shelldir' -> ok
string readme = readfile("testme2.csv") # reads file in 'shelldir'
-> ok
print readme
open "testme.csv" # *fails *to
read file in 'shelldir' ->*why?*
string file = shelldir
file +="\testme.csv"
open @file # works
<hansl>
Cheers

Not OK surely. There's no file "testme2.csv", is there?
print readme
open "testme.csv" # *fails *to read
file in 'shelldir' ->*why?*
string file = shelldir
file +="\testme.csv"
open @file # works
<hansl>
With the filename fixed, the script works here. I'm not sure why it
doesn't work for you, but I've now tweaked something in the "open" code
which might make a difference (CVS and snapshots).

It was
working, now it flags an error.
But 'open', 'append' and 'run' do now find the 'shelldir'
- Thanks Allin!

Hi there,
There seems to be some 'room for interpretation' in terms of shelldir path
recognition of functions 'readfile' and 'mread'. With current snapshot on
windows XP it suffice to code 'mread("testmat.txt")' and gretl imports
the matrix if existent in shelldir.
I'm of the opinion that this behavior is correct. One needs am anchor for working with
VBA and dynamic batch files easiest to achieve with shelldir.
Btw, ever thought of offering a 'parse function' that automatically recognizes
variables presented in this form in a txt file:
scalar num01=100
string strdir="c:\\"
...
I ask since it would be a way similar to R batch files where one can pass arguments.
Cheers
Leon

I suspect you'll find the getenv() and ngetenv() functions very nice.

Hi there,
I found some infos how to use the getenv() function in the manuel for e.g.
'USER'. Did you mean that Jack?
I think in terms of an automatic parse fucntion the getline() fucntion
would be needed and sscanf().
Cheers

I mean: suppoose you have the following hansl script called foo.inp
<hansl>
string foo = getenv("A")
scalar bar = ngetenv("N")
printf "%g kilograms of %s\n", bar, foo
</hansl>
in a Unix shell you can execute the following
<bash>
A=wood N=23.5 gretlcli -b foo.inp
</bash>
or
<bash>
A = stone; export A
N=33.3 gretlcli -b foo.inp
</bash>
and get output like
<output>
23.5 kilograms of wood
</output>
Of course you could enclose this into a shell script; I guess something
similar can be done with a Windows "batch file", or whatever they're
called.
This said, in the current CVS version, which will soon become 1.9.13, we
have quite a few new functions that make it possible to exactly what you
say: read a text file and grab numerical or string values from it, given a
proper syntax.

Here's the sort of thing that Jack had in mind:
<hansl name="getenv.inp">
# get stuff from the environment
scalar num01 = ngetenv("num01")
string strdir = getenv("strdir")
print num01
print strdir
</hansl>
At the shell prompt:
num01="100" strdir="c:\\" gretlcli -b getenv.inp
<gretl-output>
? scalar num01 = ngetenv("num01")
Generated scalar num01 = 100
? string strdir = getenv("strdir")
Generated string strdir
? print num01
num01 = 100.00000
? print strdir
c:\
Done
</gretl-output>
However, to return to your original question -- "ever thought of offering
a 'parse function' that automatically recognizes variables presented in
this form in a txt file...?", that's what "include" does.
<hansl name="auxfile.inp">
scalar num01=100
string strdir="c:\\"
</hansl>
<hansl name="includeit.inp">
include auxfile.inp
print num01
print strdir
</hansl>
