ToRRential Card processor

INTRODUCTION

ToRRential Card processor(trrc) is a command-line unix-like program to create anki cards using AnkiConnect plugin.(Think a yt-dlp, but this program is for adding cards into Anki.)

I intent to make it as a Unix-like program. Therefore it leverages a lot of Unix concepts.

# default card type is 'Basic'
$trrc --field 'fron:bakc:tags' 'What is GPL?	The GNU General Public License is a free, copyleft license for software and other kinds of works.	LICENSE::GPL'
#### Kinds of failures: 1
trrc Tip: --field 'Front:Back:Tags'

You don't have to use all those fields.
For example, if all field of a type is 'Front:Back:Source:Sound:Tags',
you can use only some of them. e.g.: 'Front:Back:Tags'.
####
Total cards: 1 Total fails: 1

See Youtube demonstration video of the author

if you decide to use this app, I highly recommend to turn apikey option in your AnkiConnect to prevent malicious attack. (It's not a fault of this app nor AnkiConnect. If the port of AnkiConnect opens without an apikey, anybody can modify your anki deck.) See also AnkiConnect Configure

INSTALLATION

pip

pip install trrc

Manual installation

pip install -r requirements.txt

pip install .

Install AnkiConnect addon in Anki.

USAGE

To solve common mistakes, I wrote a lot of examples.

Standard Input

# the blank characters except a spacebar in 'Korean Conversation' is a tab.
# the default IFS is a tab.
trrc '안녕	Hello	Korean Conversation'
          # ^         ^
          #tab character

# -F is --IFS. It sets a Internal Field Separator. Mobile devices may not
#support a tab character in their keyboard. In that case, you should use --IFS
#options. (e.g.:-F@)
trrc "back\ttestfront\tvim" -F '\t'

# you can set whatever character you want.
trrc --IFS % '안녕%Hello%Korean'
trrc -F @ '안녕@Hello@Korean'

# you can choose only part of the fields of the card type.
# you can change order of the fields.
trrc --field 'Arbitrary4thField:Arbitrary2ndFieldName:tags' 'FourthContent\tsecondContent\ttag'

# to send your card to other computer(e.g.: ip is 192.168.1.230, port is 4832).
trrc --ip 192.168.1.230 --port 4832 --file Korean_English_conversation.txt

# To use '\t' as a tab character in an standard input argument, you need to use '$' in front of the string.

trrc $'안녕\tHello\tKorean'
      ^

See also How to use '\t' in a card content?

PIPE

To use PIPE, put - in the argument.

echo 'basic_type_front_normal_tab with option	basic_type_back	basic_type_tag' | trrc -

# bash: \t
echo -e 'basic_type_front_normal_tab with option\tbasic_type_back\tbasic_type_tag' | trrc - -t 'Basic (and reversed card)' --field 'Front:Back:tag'

# bash: using a tab
echo 'basic_type_front_normal_tab with option	basic_type_back	basic_type_tag' | trrc - -t 'Basic (and reversed card)' --field 'Front:Back:tag'

# zsh: \t
echo 'basic_type_front_normal_tab with option\tbasic_type_back\tbasic_type_tag' | trrc - -t 'Basic (and reversed card)' --field 'Front:Back:tag'

# bash: using a tab
echo 'basic_type_front_normal_tab with option	basic_type_back	basic_type_tag' | trrc - -t 'Basic (and reversed card)' --field 'Front:Back:tag'

# zsh: using a tab
echo 'basic_type_front_normal_tab with option	basic_type_back	basic_type_tag' | trrc - -t 'Basic (and reversed card)' --field 'Front:Back:tag'

PIPE with cat

example_file_IFS_default.txt

If you use ' '(a tab) as a IFS like a below,

#example_file_IFS_deafult.txt
front	back	test
front2	back	test

then you don't have to use --IFS option.

cat example_file_IFS_deafult.txt | trrc -
example_file_IFS_backslash_t.txt

If you use '\t' as a IFS like a below,

#example_file_IFS_backslash_t.txt
front\tback\ttest
front2\tback\ttest

then use a command like this.

cat example_file_IFS_backslash_t.txt | trrc - --IFS '\t'

HEREDOC Standard Input

trrc --IFS '\t' - <<EOF
front	back	test
front2	back	test
EOF

HEREDOC PIPE

cat <<EOF | trrc - --IFS '\t'
front	back	test
front2	back	test
EOF

Config File

trrc's config file extension is .trrc.

See LOCATIONS and How to create a trrc config file

Locations

By default, trrc searches for rc(config) files in directories of the below. It means if you wrote the config file(only .trrc, without any file name.) there, trrc import the setting in the files if they exists in order.

macOS, Linux:

            [cardContents ...]

A command-line program to create Anki cards using AnkiConnect API.

positional arguments:
  cardContents          a string divided by IFS. the default IFS is a tab
                        character. instead of a string, It can also take a
                        file consists of strings without '--FILE' option.

options:
  -h, --help            show this help message and exit
  -D DECK, --deck DECK  set a Deck. the default is 'default'.
  -t CARDTYPE, --type CARDTYPE
                        set a card type. the default is 'Basic'.
  -i IP, --ip IP        set a ip that AnkiConnect specified. the default is
                        '127.0.0.1'.
  -p PORT, --port PORT  set a port number that AnkiConnect specified. the
                        default is '8765'.
  -f [FILE ...], --file [FILE ...]
                        set a file that contains card contents.
  -c FILE, --config FILE
                        set a config file to import config options. without
                        this option, this program searches '~/.trrc'.
  --alias SECTION       set a section of a config file to apply options.
                        without this argument, the default is 'default'.
  -F IFS, --IFS IFS     set a delimiter of card contents to use any character
                        other than a tab character. the default is a tab
                        character.
  --field COLON:DELIMITER-SEPARATED:FIELDS
                        set a card field corresponding to the cardContents.
                        the default is 'Front:Back:Tags'.
  --cloze-field COLON:DELIMITER-SEPARATED:FIELDS
                        set a cloze type card field corresponding to the
                        cardContents. The default is 'Text:Back Extra:Tags'.
  --cloze-type CLOZE_TYPE
                        set a type of a fallback for a cloze type. the default
                        is 'cloze'. if user set --field option, then the
                        default won't work. even a string contains cloze, the
                        program will process as a field unless user set
                        --cloze-type
  --toml-generate       print toml configs with current arguments. to set a
                        section of it, use it with '--toml-section' option.
  --toml-write FILE     write a config file with options used. to set a
                        section, use '--toml-section'.
  --toml-section SECTION
                        set a toml section. the default is 'untitled'.
  -H, --render-HTML     set to allow to render a HTML tag. the default doesn't
                        allow render a HTML tag, therefore <br> won't be a new
                        line.
  --apikey APIKEY       set an api key for AnkiConnect. if it is specified,
                        --debug options will mask it because of security
                        concern.
  --sync                sync Anki. if there is a card to process, trrc syncs
                        after adding the card. the default is not to sync.
  --force-add           create a card even if there is a duplicate in the
                        deck.
  --dry-run             perform a trial run without sending to Anki.
  --read-file-in-a-content
                        set to allow to replace a file in contents with its
                        contents. a default setting doesn't read it
  -v, --verbose         print a card being currently processed.
  --debug [FILE]        print debug information. if you specify FILE, trrc
                        writes debug there.
  -V, --version         print a version number and a license of trrc.

--file option

examplefile.txt

This is an example which trrc takes. IFS is a tab which is a default IFS.

Anki	Anki is a free and open-source flashcard program using spaced repetition	anki
To make a log message in python, What library Should I use?	logging	python::library

--read-file-in-a-content

Let's say you are learning Rust Language. Save this statements in a text file called 'rust_hello.txt'

fn main() {
        println!("Hello, world!");
}

and create a card with --read-file-in-a-content option

trrc '[Rust] print "Hello, world!"	rust_hello.txt	rust::println' --read-file-in-a-content

trrc will read the file 'rust_hello.txt' and use it as a content.

FAQ

How to add several tags?

A tag is a word. Therefore a spacebar will separate tags.

So for example, (IFS of tags is a tab character as a default.): CS linux::http linux::network

trrc '[linux] port 80	HTTP's port	CS linux::http linux::network'

trrc will interpret CS linux::http linux::network as a list which is ['CS', 'linux::http', 'linux::network']

How to create a trrc config file?

create config file with .trrc extension.

Let's say your previous command was

trrc -F@ --type 'Basic' --ip 127.0.0.1 --field 'Front:Back:Tags' --deck 'Computer Science' 'What is GPL?@The GNU General Public License is a free, copyleft license for software and other kinds of works.@LICENSE::GPL'

Before creating a default config file, you should check the config.

So, add --toml-generate to print configs.

Also, set a section name with --toml-section SECTION

e.g.:

trrc -F@ --type 'Basic' --ip 127.0.0.1 --field 'Front:Back:Tags' --deck 'Computer Science' 'What is GPL?@The GNU General Public License is a free, copyleft license for software and other kinds of works.@LICENSE::GPL' --toml-generate --toml-section 'CS'

But if you want to use the config as a default, then --toml-section 'default'

trrc will print,

[CS]
deck = "Computer Science"
cardtype = "Basic"
ip = "127.0.0.1"
ifs = "@"
field = "Front:Back:Tags"

If there is nothing wrong, copy the text and paste to ~/.trrc or use --toml-write

trrc -F@ --type 'Basic' --ip 127.0.0.1 --field 'Front:Back:Tags' --deck 'Computer Science' 'What is GPL?@The GNU General Public License is a free, copyleft license for software and other kinds of works.@LICENSE::GPL' --toml-section 'CS' --toml-write ~/.trrc

And you can reuse your config with --alias CS.

Also you can overwrite the config with an argument,

--alias CS --IFS ^

It will use CS config but IFS is '^'.

How to reuse the specific config?

If your config file has 'CS' section, the append --alias 'CS' in your command.

Tip for writing your own script.

In the case with your own script, for a backup purpose, I recommend to create a temp file to use --file option or PIPE.

Avoid to use the modules of the library directly because it's alpha version.

This program's License is GPL3. See License.

If you need to submit your code using trrc, discuss with the person concerned about the license.

How to use '\t' in a card content?

Yes, It's possible to interpret \t as a tab. But in a default ' '(tab) IFS, the shell behavior that doesn't interpret '\t' as a tab character is a normal behavior, therefore if you add a card using '\t' as a IFS in a standard input, you need to use --IFS '\t' or put $ in front of single qoute.

set -x
echo 'front	back	test'
echo 'front\tback\ttest'
echo $'front\tback\ttest'
set +x

How to add a new line?

Use \n to make a new line.

trrc 'First line\nSecond line	back	tag'

How to open a port?

Basically, when you are running anki with an AnkiConnect addon, the port(default is 8765) of AnkiConnect opens.

But if your want to send a card using trrc from outside of your computer which is running Anki with AnkiConnect, you may need to modify firewall option on the computer or a router.

Contribution

Thank you for letting me know the bug! Please report the bug in issue tracker.

Personally I like this app as a method to add cards and use daily, so I will keep developing it. Because I'm trying to get a job, an update delivery can be slow. But after getting a job, I will learn some good clean code conventions and apply it.

Currently I'm writing tests to guarantee a basic functionality, documents and comments on codes.

Also there won't be massive changes for a while. Because I think I should redesign the program for scalability. Think about making card from 'git-diff'. To make such functions quickly I need to redesign.

If there is changes, I'll write how it changes, examples on how to change your codes.

I'm happy to accept criticism, PR, and so on.

There are a lot of grammar mistakes. English is not my language. Catch! PR! PLEASE!

If you're good at unix, linux, or shell, please enlighten me! I really want to hear about book recomendations, cli program to benchmark and so on.
