Basic Examples

Use a function meant for lists on a string:

In[1]:=

Out[1]=

Create new string functions from existing functions:

In[2]:=

Out[2]=

In[3]:=

Out[3]=

Rotate a string:

In[4]:=

Out[4]=

In[5]:=

Out[5]=

Get a random permutation of a string:

In[6]:=

Out[6]=

Replace all vowels:

In[7]:=

Out[7]=

Insert spaces between each letter:

In[8]:=

Out[8]=

And many more:

In[9]:=

Out[9]=

In[10]:=

Out[10]=

In[11]:=

Out[11]=

In[12]:=

Out[12]=

In[13]:=

Out[13]=

In[14]:=

Out[14]=

In[15]:=

Out[15]=

In[16]:=

Out[16]=

Scope

Functions created by StringFunction behave as though they were Listable:

In[17]:=

Out[17]=

In[18]:=

Out[18]=

This is similar to many of the built-in string functions:

In[19]:=

Out[19]=

Use a custom function in StringFunction:

In[20]:=

Out[18]=

In[21]:=

Out[21]=

If the given function produces nested lists of strings, the list structure will be preserved:

In[22]:=

Out[22]=

Characters are separated using Characters instead of byte values, so encoding is preserved:

In[23]:=

Out[23]=

Properties and Relations

The given function is applied to a list of strings:

In[24]:=

Out[24]=

In[25]:=

Out[25]=

StringFunction applies f to Characters[string] and joins the result:

In[26]:=

Out[26]=

In[27]:=

Out[27]=

Possible Issues

The given f must produce a string or lists of strings from its output:

In[28]:=

Out[28]=

In[29]:=

Out[29]=

Validity isn’t determined until evaluation of StringFunction[…][args]:

In[30]:=

Out[30]=

In[31]:=

Out[31]=

Neat Examples

Create a scrolling marquee to experience that 90’s website nostalgia:

In[32]:=

In[33]:=

Out[33]=
