[PATCH 0/5] replace strbuf_expand()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



strbuf_expand() is used to interpolate placeholders that start with a
percent sign (%) in strings.  It invokes a callback function to handle
those placeholders, expands "%%" to "%" itself and copies unrecognized
placeholders verbatim.  Context info for the callback needs to be
passed in via a void pointer, e.g. to a custom struct.

There is a better, simpler way: Use a loop to iterate over placeholders
and access variables directly, without the need to take a detour through
a context struct.  This series converts the callers of strbuf_expand()
to use the new helper strbuf_expand_step(), removing the overhead that
comes with using a callback.

  pretty: factor out expand_separator()
  strbuf: factor out strbuf_expand_step()
  replace strbuf_expand_dict_cb() with strbuf_expand_step()
  replace strbuf_expand() with strbuf_expand_step()
  strbuf: simplify strbuf_expand_literal_cb()
