Shemu
|
||||
=====
|
||||
|
||||
When harvest comes, Shemu tells you if you have correctly submitted your work.
|
||||
|
||||
Shemu is a HTML interface looking for an extracted tarball for each students in
|
||||
each projects.
|
||||
|
||||
|
||||
Compilation
|
||||
-----------
|
||||
|
||||
This program is written in Go. It has no dependancy, you can compile it with
|
||||
the following command:
|
||||
|
||||
```shell
|
||||
go build
|
||||
```
|
||||
|
||||
|
||||
Projects
|
||||
--------
|
||||
|
||||
Shemu takes as argument a path to a directory containing projects.
|
||||
|
||||
The tree exptected looks like:
|
||||
|
||||
rendu/
|
||||
TP1/
|
||||
login_x/
|
||||
...
|
||||
mercie_d/
|
||||
...
|
||||
TP2/
|
||||
login_x/
|
||||
...
|
||||
mercie_d/
|
||||
...
|
||||
|
||||
In the above tree, 2 projects are defined: named `TP1` and `TP2`, from their
|
||||
directory name.
|
||||
|
||||
|
||||
Students
|
||||
--------
|
||||
|
||||
A file with students list is expected, in CSV format.
|
||||
|
||||
A line looks like:
|
||||
|
||||
```csv
|
||||
Mercier,Pierre-Olivier,mercie_d,64170,github@nemunai.re,0123456789
|
||||
```
|
||||
|
||||
The third column is used has student identifier. It is this identifier that is
|
||||
search in each project directory.
|
||||
|
||||
|
||||
Usage
|
||||
-----
|
||||
|
||||
```shell
|
||||
./shemu -students ~/projects/students.csv -path ~/projects/
|
||||
```
|
||||
|
||||
Another convinient way to use it is to launch and forget:
|
||||
|
||||
```shell
|
||||
nohup ./shemu -bind :8079 -title "Submissions title" -students ~/projects/students.csv -path ~/projects/ &
|
||||
```
