String commonness in docs for different Perl versions
Nicolas François has provided some interesting figures about the differences and commonness between the documentations for the Perl versions supported by this project.
Utilizing po4a and the gettext-tools he compared the three supported versions (5.6.2, 5.8.8 and 5.9.4). To get to this information, the documents were split into gettext-”strings”. These could then be compared and counted. Here is what he found out:
| Version | Number of Strings |
|---|---|
| 5.6.2 | 20959 |
| 5.8.8 | 29762 |
| 5.9.4 | 31882 |
This shows how the documentation has grown — especially between the last two “stable” releases. Wish us good luck for translating all this! But wait! There’s more — and hope:
| Strings common to all versions | 16699 |
| Strings common between 5.8.8 and 5.9.4 | 12223 |
| Strings of 5.9.4, not in 5.8.8 | 2960 |
| Strings of 5.8.8, not in 5.9.4 | 840 |
| Strings unique to 5.6.2 | 4260 |
Here we can see that about half of the documentation has more or less stayed the same, even between major releases. In fact the numbers might be a bit misleading as a typo fix in one of the strings will automatically mark it as “changed”.
