If I use the terminal to start the program it has no problem using the
file. There are multiple files in multiple directories so I was
looking
for
a way to just double click them and have them run. If it turns out
that
I
must make changes to or for each of the files it will be easier to
just
keep
using the terminal. I've only been using Ubuntu for a few months so
I
was
surprised that the program could not see a file that is in the same
directory.
Regards, Jim
The problem is ubuntu doesn't run the script from the directory it's
in
so
it's looking for wxPython.jpg somewhere else.
OK, I mistakenly thought that double-clicking on file in Nautilus
would
take care of the path info.
In my reply above I also mentioned that I tried by dropping it on a
Launcher on the top panel and that the command the launcher uses is
usr/bin/python2.6. Is there a way that the command can be changed so
that
it will look in the same directory the python script is in for any file
it
needs?
Thanks, Jim
Not sure if you got my previous email but you could try writing the bash
script I posted (with the $1 line to get the path) and setting that as
your
launcher, I think it should work.
Let me know if you didn't get it or it doesn't work.
HTH,
Adam.
I got it, got sidetracked and then forgot to look at it again. Thanks
for
reminding me. Your idea works, but with one little downside. The
directories I am working with are chapters in a book. So as I move from
chapter to chapter I will need to change the bash script, but this seems
to
be less typing than using the terminal.
Thanks, Jim
Ok cool, glad it works. It might be possible to get the path so you don't
have to set it each time, try this:
#!/bin/bash
IFS="/"
path=($1)
cd $(path[0:#path[*]])
python $1
# Warning, I'm not exactly a competent bash programmer so this may not
work
:-p
Let me know if you need a hand to fix it,
HTH,
Adam.
I tried the new bash code but when I dropped a file on the launcher it just
flashed an gave no output. So I tried running the bash script
(name=runpython) in a terminal and got this error:
/home/jfb/runpython: line 4: path[0:#path[*]]: command not found
Python 2.6.5 (r265:79063, Apr 16 2010, 13:57:41)
[GCC 4.4.3] on linux2
Type "help", "copyright", "credits" or "license" for more information.
I know even less about bash than you do, so I don't where to start to debug
this.
Thanks, Jim
Ok then, this time it's tested and not just improvised, here we go:
#!/bin/bash
script=$1 # Full path for calling the script later
orig_IFS=$IFS # This is to reset IFS so that "script" is correct (otherwise
has spaces instead of /)
IFS="/"
path=( $1 )
IFS=$orig_IFS
last_ind=${#pa...@]} # Works out the length of path
let "last_ind -= 1" # Sets last_ind to index of script name
len_path=${pa...@]:0:last_ind} # Gets the path without the script name
let "len_path=${#len_path[0]} + 1" # This gives the length of the script
string upto just before the last /
cd ${scri...@]:0:len_path} # cds to the path
python script
As pretty much my first non-trivial bash script it's probably horrible but
it seems to work.
HTH,
Adam.
There must be something different in our setups because it did not work
for me. If I run it from a terminal I get:
j...@jfb-ubuntu64:~$ /home/jfb/runpython_test bitmap_button.py
/home/jfb/runpython_test: line 12: cd: b: No such file or directory
python: can't open file 'script': [Errno 2] No such file or directory
j...@jfb-ubuntu64:~$
Thanks Jim
