1 YARRG - Yet Another Revenue Research Gatherer
2 =============================================
8 - screenscrape the commodities trading screen
9 - produce the results as a tab separated values file
10 - upload the results to the YARRG and PCTB servers
12 To build, install the dependencies, cd to this directory and type `make'.
14 To screenscrape and upload to both servers, select `trade
15 commodities' from the hold of a vessel or building, and run:
17 We upload to the dedicated yarrg server http://yarrg.chiark.net/,
18 and also to the PCTB server http://pctb.crabdance.com/.
20 Or, for example, for a tab-separated values dump:
21 ./yarrg --tsv >commods.tsv
23 While it is capturing the screenshots, do not move the mouse or use
24 the keyboard. Keyboard focus must stay in the YPP client window. If
25 you use Gnome or KDE you must raise the YPP client window so that it
26 is completely unobscured - the yarrg program tries to do this but
27 metacity and kwin do not honour the request.
33 Setting the operation mode:
34 --find-window-only Just check that we can find the YPP client window.
35 --screenshot-only Page through and take screenshots, do not OCR
36 --analyse-only | --same Process previously taken screenshots
37 --everything (default) Take screenshots and process them
39 Options to vary the processing:
40 --single-page One screenful, no paging - results will be incomplete
41 --quiet Suppress progress messages
42 --screenshot-file F Store or read screenshots in F rather than _pages.ppm
43 --window-id ID Specified X window is the YPP client - do not search
44 --edit-charset Enable character set editing. See README.dictionary.
45 --no-edit-charset Do not edit charset even if _local-char*.txt exists.
46 --find-island Find and print the ocean and island. Suppresses OCR
47 and output unless used with result processing option.
48 --test-servers Set default servers to be the test servers, not
49 the real live ones (doesn't affect explicit settings).
51 Controlling what happens to the results - one or more:
52 --upload (default) Upload to both the YARRG and PCTB servers
53 --upload-pctb Upload to the PCTB servers
54 --upload-yarrg Upload to the YARRG servers
55 --tsv Print data as clean tab-separated-values file
56 --raw-tsv Dump the raw (not deduped, unsorted) OCR'd data
57 --best-prices Print best buy and sell price for each commodity
58 --arbitrage Print arbitrage opportunities
60 Privacy options, which control conversations with the dictionary server:
61 --dict-local-only * Do not talk to the server even to fetch new dictionary.
62 --dict-read-only * Only fetch new dictionary, do not submit new entries.
63 --dict-anon Don't quote pirate name if submitting entries.
64 --dict-submit Submit entries quoting my pirate name. (default)
65 Please do not use options marked * with --upload. See README.privacy.
67 Options to override which servers we talk to:
68 --yarrg-server HOST|URL When uploading to YARRG, use HOST or URL.
69 --pctb-server HOST|URL When talking to PCTB, use HOST or URL.
70 --dict-submit-url URL Submit dictionary updates here (default: use yarrg).
71 --dict-update-from SRC Fetch updated master dictionary with rsync from SRC.
72 Or set the environment variables
73 YPPSC_YARRG{_YARRG, _PCTB, _DICT_UPDATE, _DICT_SUBMIT}
76 Installation requirements
77 -------------------------
79 Your X server must be 24bpp (or better).
81 This program has quite a few dependencies:
84 - For building, C compiler and build environment build-essential
85 - pnm library, including dev files for building libnetpbm10-dev
86 - pnm command line utilities for image manipulation netpbm
87 - X11 libraries, including dev files for building libx11-dev
88 - XTEST library, including dev files for building libxtst-dev
89 - Perl-compatible regexp library, including dev files libpcre3-dev
90 - Tk interpreter /usr/bin/wish tk8.4
91 - Perl module XML::Parser libxml-parser-perl
92 - Perl module JSON::Parser libjson-perl
93 - XTEST extension in the X server (part of X package)
94 - Perl interpreter and basic modules perl (usu.installed)
96 On other Linux distros the packages may have different names, but
97 these should be roughly right for Debian and its derivatives. You can
98 install them with this rune:
99 sudo apt-get install git-core build-essential libnetpbm10-dev netpbm libx11-dev libxtst-dev libpcre3-dev tk8.4 libxml-parser-perl libjson-perl
102 The supplied helper programs
104 commod-results-processor
106 must (currently) also be in the current working directory when you run
107 the main yarrg program.
109 The data files (see README.files) are also left in the current working
110 directory. There is not yet any feature to have the data files and
111 helpers be somewhere else.
117 If you need to report a bug, for example an inability to recognise,
118 please be sure to remember the exact error message and circumstances.
119 Also, for recognition problems there will probably be a very useful
120 screenshot file called `_pages.ppm'. This is likely to be very large
121 so don't just email it to me, but if you can put it up on a webpage
122 for me to download that will help. At least keep a copy of it.
124 If the problem is a failure to cope with some particular YPP client
125 display and is reproducible, try running:
126 ./yarrg --raw-tsv --single-page
127 If this reproduces the problem, please email me the screenshot file
128 _pages.ppm, which will consist only of the single screen, plus the
129 error messasge. I'll then be able to understand what's wrong,
136 The main purpose of this program is to connect to the YARRG and PCTB
137 servers and upload data. It will do that if you run it with --upload.
139 This program will also, by default, talk to the dictionary server I
140 have set up: to download updated image dictionaries, and to upload new
141 dictionary entries which you create with the yarrg client dictionary
142 GUI. This feature is mentioned in and controllable in the GUI itself,
143 so it won't happen without you knowing about it.
145 The uploads will by default mention your ocean and pirate name; if you
146 don't want that, pass the --dict-anon option, or untick the box in the
149 See README.privacy for full details.
