Usage

baca [FLAGS] [SUBCOMMAND]

FLAGS:
    -U, --force-update    Force update check
    -h, --help            Prints help information
    -u, --no-update       Disable update check
    -V, --version         Prints version information
    -v, --verbose         Sets the level of verbosity

SUBCOMMANDS:
    clear      Removes the whole `.baca` directory
    config     Opens editor to edit BaCa configuration
    details    Gets submit details
    help       Prints this message or the help of the given subcommand(s)
    init       Initializes current directory as BaCa workspace
    last       Prints details of the last submit
    log        Prints last (default 3) submits
    refresh    Refreshes session, use in case of cookie expiration
    submit     Submits file
    tasks      Prints available tasks

Workspace initialization: `init`

Initializes current directory as BaCa workspace, similar to git init. Currently, passwords are stored in plain text. User will be asked for credentials, if not provided.

baca init

-h, --host <host>            BaCa hostname, ex. mn2020
-l, --login <login>          BaCa login
-p, --password <password>    BaCa password

Example, running on Metody numeryczne 2019/2020 with no login prompt:

baca init --host mn2020 --login jaremko --password PaSsWorD

Re-login: `refresh`

Refreshes session, use in case of cookie expiration.

baca refresh

Submit: `submit`

Submits given file to specified task. Will prompt the user for task, if not provided.

Optional parameter --task <id> explicitly sets problem to submit to. Use baca tasks to see what ids are available.
Optional parameter --zip will zip given file before submitting. The archive is saved as source.zip.
Optional parameter --rename will rename file before submitting and zipping.
Optional parameter --language <language> explicitly sets input file language.
submit config opens editor to edit submit config.
submit clear clears saved submit config.

baca submit -t <task_id> -f <filename> [optional -l <language>] [optional --zip] [optional --rename or -r <new_filename>]

Example:

> baca submit -f hello.cpp
✔ Choose task: · [E] Metoda SOR
Submitting hello.cpp to task [E] Metoda SOR (C++ with file support).

Saving task info

If you don't want to type task info (id and filename) every time you submit, you can use --save flag to save it. Keep in mind, that config provided through parameters will override saved data. To completely remove saved data use baca submit clear. To disable automatic prompt for save, use --no-save.

Example:

> baca submit -f hello.cpp -t 5 --save
Submitting hello.cpp to task [E] Metoda SOR (C++ with file support).
> baca submit
Submitting hello.cpp to task [E] Metoda SOR (C++ with file support).

Recent submits: `log`

Prints statuses of a couple of recent submits (default 3). Parameter -t <task_id> lets you print logs for specific task. Task ID can be found by baca tasks.

baca log [optional: number] [optional: -t <task_id>]

Example:

> baca log

TEST_BACA_HOST=<host>

Setting log levels

Log levels are configured by -v flag.

no flag - no additional logs
-v - info
-vv - debug
-vvv or more - trace

Troubleshooting

Unfortunately, Baca still uses deprecated TLSv1 protocol which is not supported on your system. Sorry!
Since Baca uses deprecated TLSv1 protocol, you have to enable TLSv1 to use it. You can do it multiple ways, some of which are described below.
- Every method presented below assumes that a OpenSSL config file exists at ~/.openssl.cnf. Inside of it you can specify the security level, which changes the TLS version. You can find more information by clicking here.
  Example config:
```
openssl_conf = openssl_init

[openssl_init]
ssl_conf = ssl_sect

[ssl_sect]
system_default = system_default_sect

[system_default_sect]
CipherString = DEFAULT@SECLEVEL=1
```
- Supplying the environmental variable only for the command that follows: OPENSSL_CONF=~/.openssl.cnf baca.
- Creating an alias in your shell's RC file. This enables this specific OpenSSL config for this specific terminal instance, until it's closed. Example:
  1. In .zshrc append alias bacaSSL="export OPENSSL_CONF=~/.openssl_baca.cnf".
  2. Restart the terminal or source /path/to/.zshrc.
  3. Use baca-cli as you would normally.
- Not recommended! It is possible to overwrite the global OpenSSL config to allow for TLSv1 connections everywhere, but it is really insecure to do so. Thus we will not show how to do it.
