Different behavior when executing ksh script in Alfred and in terminal

[vdesabou]

Hi,

 

I have a difference of behavior when I execute a ksh script in a "Run script" action in Alfred and in a terminal.

 

The code is as following:

SPEC_CHAR="ÀÁÂÃÄÅÆÇÈÉÊËÌÍÎÏÐÑÒÓÔÕÖØÙÚÛÜÝÞßàáâãäåæçèéêëìíîïðñòóôõöøùúûüýþÿ"
NORM_CHAR="AAAAAAACEEEEIIIIDNOOOOOOUUUUYPSaaaaaaaceeeeiiiionoooooouuuuyby"

mystring="têté"
mystring=$(print $mystring | sed 'y/'${SPEC_CHAR}'/'${NORM_CHAR}'/')
echo "$mystring" 

 

When I execute in terminal, I have:

 

/Users/vincent/Downloads>

 

ksh repro.ksh

tete

 

But when I execute it in Alfred (see workflow with reproduction here http://d.pr/f/ShJl ), I get an empty string for $mystring

 

Any idea what's wrong here?

 

Mac OS 10.8.3

Alfred: 2.0.2

Reproducible: Yes

I think this may be either an issue with not importing environments or your workflow itself, I am moving into workflow questions so it can get some more eyes on the issue to maybe shed some light.

Still not sure of the exact fix, but so far it appears that the issue lies in sed. If I manipulate it to search a single char and replace, it works perfectly. If I change it back to do the full replace that you are attempting, it fails. I'll continue to tinker with it and see what I can find.

Yes, it seems related to sed indeed, but that's strange that it is only happening when using Alfred.

 

I've simplified the code:

 

Looks like using combination of y/"accented character" is causing the issue:

mystring="Têté"
mystring=$(echo "$mystring" | sed y/ê/e/)
echo "$mystring"

 

is not working

 

If i do:

 

mystring="Têté"
mystring=$(echo "$mystring" | sed y/t/b/)
echo "$mystring"

 

or :

mystring="Têté"
mystring=$(echo "$mystring" | sed s/ê/e/)
echo "$mystring" 

 

 

It is working

 

Weird...

 

Thanks for your help, I'm getting crazy :-)

Hi David,

 

I believe this is because LANG was not set when invoking the script with Alfred.

 

In terminal, If I do:

$ echo $LANG
fr_FR.UTF-8

$ ksh repro.ksh
tete

$ unset LANG


$ ksh repro.ksh
sed: 1: "y/ÀÁÂÃÄÅÆÇÈÉ� ...": transform strings are not the same length

 

 

So I added in the "repro2" repro.ksh script, export LANG='fr_FR.UTF-8' and now it works!

 

Problem solved. Thanks
