1 | simple sample
2 | =============
3 |
4 | 一番簡単なHello worldサンプル。
5 |
6 | 「ログインせずに」NAFUDAドライブの中身だけでハックする！
7 |
8 | # 試し方
9 |
10 | - このディレクトリの`startup.sh`をNAFUDAドライブのトップに設置する
11 | - 名札を再起動する
12 | - 「hello nafuda world!」
13 |
14 |
15 | # 概要説明
16 |
17 | systemdに登録された`nafuda-bootup.service`(`electronic_badge_2018/bootup/bootup.sh`)は、最後にNAFUDAドライブの直下にstartup.shがあればそれを起動します。
18 |
19 | > ※ その場合、simple-nafudaは起動されません。
20 |
21 | この`starup.sh`は無限ループで名札内に保存されている `show_txt`や`show_img`コマンドを用いて画像を表示しています。
22 |
23 | このシェルスクリプトを改変することで、簡単なものならばログインなしにプログラムが可能です。
24 |
25 | > ※ エラー原因を特定するなどを考えるとなかなか難しいですが…
26 |
27 | > ※ `show_txt`や`show_img`の使い方はGitHubのレポジトリのそれぞれをみてください。
28 |
29 | > ※ この`startup.sh`はroot権限で起動されます
30 |
31 |
32 | # たとえば他の例
33 |
34 | ```
35 | # nictの現在時刻取得jsonをたたいて表示してみるとか
36 | curl http://ntp-a1.nict.go.jp/cgi-bin/json | show_txt -
37 |
38 | # 画像をDLして表示するとか
39 | # ※ /mnt/virtual_sdは初期ではread onlyでマウントしているため、
40 | # 書き込みが必要であれば/tmpを指定してください。
41 | curl 'https://builderscon.io/static/images/mrbeacon-001.png' > /tmp/bcon.png
42 | show_img /tmp/bcon.png
43 | # （もしご自身でmount_vsd_rwを用いて再マウントすればその限りではありませんが、
44 | # busyだと失敗するので、やはりログインできるようになってからが良いでしょう）
45 | ```
46 |
47 | > ※ `show_img`の実体は `/home/pi/electronic_badge_2018/show_img/show_img.py`
48 |
49 | > ※ `show_txt`の実体は `/home/pi/electronic_badge_2018/show_txt/show_txt.py`
50 |
51 | # おまけ
52 |
53 | ## 各インタプリタへのパス
54 |
55 | ```
56 | /usr/bin/python3
57 | ※ /usr/bin/python は python2なので推奨はしません
58 | /usr/bin/perl
59 | ```
60 |
61 | ## 「とにかくなにか実行して結果が知りたい」
62 |
63 | `show_txt`をつかえば、epaperに表示することが可能です。
64 |
65 | ```bash
66 | #!/bin/bash
67 | ls -al ~/ 2>&1 | show_txt -
68 | # 2>&1 をいれないと、エラー出力がすてられます
69 | ```
70 |
71 | > ※ 大変なので、ログインしたほうが良いとおもいます！
72 |
73 |
74 | ## git cloneやpullできるのでは？
75 |
76 | やってやれないことはありません。
77 |
78 | ```bash
79 | export GIT_SSH_COMMAND="ssh -o UserKnownHostsFile=/dev/null -o StrictHostKeyChecking=no"
80 | git -C /home/pi clone https://github.com/builderscon/electronic_badge_2018.git 2>&1 | show_txt -
81 | git -C /home/pi pull 2>&1 | show_txt -
82 | ```
83 |
84 | > ※ コンフリクトしていたときに解消が難しいので、おすすめはできませんが…
85 |
86 | ## 「あれやこれやができるのでは？」
87 |
88 | root権限で、TTYが不要で、CLIで実行できることなら、大体できるとおもいます。
89 |
90 | ## 「危険では？！」
91 |
92 | microSDを抜いてマウントすればなんでもできますし、NAFUDAドライブの中にはデフォルトパスワードもみえるので、電子名札はそういう思想です。
93 |
94 | 電子名札には機密情報をいれないようにしましょう。入れる場合は自己責任。
95 |
96 | ## Do you want PHP?
97 |
98 | phpがお好き？そう、PHPもいれられますね。以下のstartup.shを作成して再起動すればインストールできるよ！
99 |
100 | ```bash
101 | #!/bin/bash
102 | echo "php installing now..." | show_txt -
103 | # とても時間かかります！
104 | sudo apt -y install php 2>&1 | show_txt -
105 | LOG=`which php`
106 | LOG="${LOG} `php -v`"
107 | echo "${LOG}"
108 | echo "finished. ${LOG}" | show_txt -
109 | ```
110 |
111 |
112 | あとは、たとえば以下みたいなコードをかけば表示もできます！
113 |
114 | ```php
115 | ※ NAFUDAドライブは読み込み専用でマウントされているので、一時ファイルを作成するときは /tmp/ に作成してください。
123 |
124 | > ※ もしご自身の自己責任でmount_vsd_rw.shを用いて再マウントすればその限りではありません。
