I have tried WordWrap from the store. I cannot get it to work, and neither the demo workspace. It asks if I want to update it and then crashes or has a blank workspace.

 

 

Wordwrap may be better than splitting into fields, but it is very promising if it worked.

---

There is no output attribute from WordWrap, "wrapped" does not appear.

Hi,

 

 

I don't think there is the ideal solution except scripting. An example of Python script is:   import fmeobjects   def splitText(feature):     text = feature.getAttribute('text_line_data')     if not text:         return     count = 0     str = ''     for word in text.split():         if 100 < len(str) + 1 + len(word):             feature.setAttribute('bound%d' % count, str)             count = count + 1             str = ''         if len(str) == 0:             str = word         else:             str = '%s%s%s' % (str, ' ', word)     if 0 < len(str):         feature.setAttribute('bound%d' % count, str)         count = count + 1     feature.setAttribute('number_of_fields', count)

 

 

Try calling this script through a PythonCaller transformer.

 

Hope this helps.

Thanks Takashi, that worked well for some fixed widths and output fields.

 

It has inspired me to use more Python in my workspaces.

 

 

IA bit more work is required to make it general enough to replace WordWrap in the store I did try to read in a published parameter to avoid hardcoding the width without success. I would then have to set the output widths as well, and dynamically add the required number of fields. All possible with enough incentive.

 

 

I did rewrite it but it does the same thing:

 

 

import fmeobjects

 

def splitText(feature):

 

    ''' split paragraph at words less than field_width chars'''

 

    text = feature.getAttribute("bound")

 

    field_width = 100 # I wish! getParameter("MaxWidth")

 

    lstWord = text.split()

 

    lstFld = t]

 

    fld = lstWord.pop(0)

 

    while lstWord:

 

        part = lstWord.pop(0)

 

        if len(fld) + len(part) <= field_width + 1:

 

            fld = fld + " " + part

 

        else : # start new field

 

            lstFld.append(fld)

 

            fld = part

 

    lstFld.append(fld) # final remainder

 

    count = len(lstFld)

 

    for n in range(count):

 

        feature.setAttribute("bound%d" % n,lstFldln])

 

    feature.setAttribute("splits",count)

A name and value pair of a parameter is stored in a dictionary named FME_MacroValues internally. You can get the value of a parameter through this dictionary, for example:

 

    field_width = int(FME_MacroValuesu'MaxWidth'])

 

Note parameter values are always stored as character strings, so it's necessary to convert the value type using a cast syntax like 'int(...)' if the value has to be treated as a numeric value in the script.

Hi,

 

 

no need to re-invent the wheel with Python, there is already an excellent module that does word wrapping ;-)

 

 

-----

 

import fmeobjects import textwrap   def TextWrapper(feature):     text = feature.getAttribute("text_line_data")     maxLength = int(FME_MacroValuesa'MaxWidth'])     parts = textwrap.wrap(text, maxLength)     feature.setAttribute('number_of_parts', len(parts))     if parts:         feature.setAttribute('parts{}', parts)

 

-----

 

Expose the attributes "parts{}" and "number_of_parts".

 

 

This outputs all parts to the list "parts{}", which I find much cleaner than using named attributes.

 

 

I also think this solution is much more Pythonic.

David, that's Pythonic! I've re-invented the wheel. Thanks for the textwrap module.
