Hello everyone, |
| 2 |
|
| 3 |
This year I will work on the libbash runtime project. A short |
| 4 |
introduction for this project: |
| 5 |
|
| 6 |
Libbash will enable programs to use Abstract Syntax Trees(AST) to parse |
| 7 |
and interpret *shell* scripts directly instead of using regular |
| 8 |
expressions. Most of bash 3.2 syntax will be supported. This will be a |
| 9 |
great benefit to programs both outside and inside Gentoo, including |
| 10 |
Portage/Paludis and repoman. |
| 11 |
|
| 12 |
For more information, I wrote an introduction[1] explaining its |
| 13 |
potential usage and benchmark. There's also a home page[2] for this |
| 14 |
project. You can find out the rationale, plan and detailed progress |
| 15 |
there(most content comes from my GSoC proposal). |
| 16 |
|
| 17 |
As the first weekly report, I'd like to briefly talk about our current |
| 18 |
progress. I've been contributing to this project since March so we have |
| 19 |
done a lot of things. Here's a summary: |
| 20 |
* Parser grammar improvement |
| 21 |
* Build system improvement(C++ hidden visibility, developer flags, |
| 22 |
gcov, etc.) |
| 23 |
* Shell arithmetic |
| 24 |
* Variable(string, array) definition and reference |
| 25 |
* Variable expansion |
| 26 |
* Shell pattern matching |
| 27 |
* Compound statement(if, for, while, until, case) |
| 28 |
* Shell test expression |
| 29 |
* Command execution and substitution |
| 30 |
* Shell function |
| 31 |
* Several shell built-ins(source, let, etc.) |
| 32 |
* Utilities(ast_printer, reimplemented version of Paludis instruo, etc.) |
| 33 |
For more detailed information, please visit our home page[2], my blog[5] |
| 34 |
or our git repository[3]. |
| 35 |
|
| 36 |
Here are some resources we have: |
| 37 |
* CI server(not public accessible yet) |
| 38 |
* Agilefant server(for Scrum) |
| 39 |
* Test coverage report |
| 40 |
* Callgrind and massif target |
| 41 |
* Github repository[4] (latest commits) |
| 42 |
* Canonical repository[3] (reviewed commits) |
| 43 |
* Home page[2] |
| 44 |
* #gentoo-libbash IRC channel |
| 45 |
|
| 46 |
Now we can generate correct metadata for 2934 ebuilds(There are 27289 |
| 47 |
in total). We will get more and more during the summer. |
