We test our translations by taking the original untranslated string

(e.g. msgid) and prepend a prefix character and then append a suffix

character. The test consists of asserting that the first character in the

translated string is the prefix, the last character in the translated string

is the suffix and the everything between the first and last character exactly

matches the original msgid.

We use unicode characters not in the ascii character set for the prefix and

suffix to enhance the test. To make reading the translated string easier the

prefix is the unicode right pointing arrow and the suffix left pointing arrow,

thus the translated string looks like the original string enclosed in

arrows. In ASCII art the string "foo" would render as:

-->foo<--

Given an entry in a pot or po file return a set of the

programming languges it was found in. It needs to be a set

because the same msgid may appear in more than one file which may

be in different programming languages.

Note: One might think you could use the c-format etc. flags to

attached to entry to make this determination, but you can't. Those

flags refer to the style of the string not the programming

language it came from. Also the flags are often omitted and/or are

inaccurate.

For now we just look at the file extension. If we knew the path to

the file we could use other heuristics such as looking for the

shbang interpreter string.

The set of possible language types witch might be returned are:

* c

* python

optional precision and an optional length modifier. See "man 3

Each item in the returned list is a dict whose keys are the

sub-parts of a conversion specification. The key and values are:

fmt

The entire format conversion specification

fmt_arg

The positional index of the matching argument in the argument

list, e.g. %1$ indicates the first argument in the argument

will be read for this conversion, excludes the leading % but

includes the trailing $, 1$ is the fmt_arg in %1$.

flags

The flag characaters, e.g. 0 is the flag in %08d

width

The width field, e.g. 20 is the width in %20s

precision

The precisioin field, e.g. .2 is the precision in %8.2f

length

The length modifier field, e.g. l is the length modifier in %ld

conversion

specification character in %ld
