| 142 | DESCRIPTION
|
|---|
| 143 | This script parses a list of external links found in the OniGalore wiki
|
|---|
| 144 | (which is dumped by the Oni2.net server periodically in a particular
|
|---|
| 145 | format), validates them using the Unix tool 'curl', and produces a report
|
|---|
| 146 | of which links were "OK" (responded positively to an HTTP query), which
|
|---|
| 147 | were "RD" (responded with a 3xx redirect code), which could be "IW"
|
|---|
| 148 | (interwiki) links, which are "EI" (external internal) links and could be
|
|---|
| 149 | intrawiki links, and which were "NG" (no good; a negative response to the
|
|---|
| 150 | query). This report can then be automatically uploaded to the location of
|
|---|
| 151 | your choice. The script can also suggest Internet Archive snapshots for
|
|---|
| 152 | "NG" links, and take screenshots of "OK" links for visual verification by
|
|---|
| 153 | the reader that the page in question is the one intended to be displayed.
|
|---|
| 154 |
|
|---|
| 155 | You must pass this script the URL at which the list of links is found
|
|---|
| 156 | (--links) and the path where the directory of logs should be outputted
|
|---|
| 157 | (--output). All other arguments are optional.
|
|---|
| 158 |
|
|---|
| 159 | OPTIONS
|
|---|
| 160 | --help Show this page.
|
|---|
| 161 | --links URL (required) URL from which to download the CSV
|
|---|
| 162 | file with external links. Note that this URL can
|
|---|
| 163 | be a local file if you supply a file:// path.
|
|---|
| 164 | --output DIR (required) Unix path to directory in which Val
|
|---|
| 165 | should place its reports.
|
|---|
| 166 | --exceptions URL In order to remove links from the report which
|
|---|
| 167 | Val finds an issue with but which you regard as
|
|---|
| 168 | OK, list those desired exceptions on a wiki page.
|
|---|
| 169 | See the sample file "exceptions.pdf" for the
|
|---|
| 170 | required format of the page. Note that this URL
|
|---|
| 171 | can point to a local file if you supply a path
|
|---|
| 172 | beginning with "file://".
|
|---|
| 173 | --record-ok-links Log a link in the report even if its response
|
|---|
| 174 | code is "OK".
|
|---|
| 175 | --show-added-slashes Report on redirects that simply add a '/' to the
|
|---|
| 176 | end of the URL.
|
|---|
| 177 | --show-https-upgrades Report on redirects that simply upgrade a
|
|---|
| 178 | "http://" URL to a "https://" URL.
|
|---|
| 179 | --show-yt-redirects Report on redirects that expand a youtu.be URL.
|
|---|
| 180 | --suggest-snapshots-ng Query the Internet Archive for a possible
|
|---|
| 181 | snapshot URL for each "NG" page.
|
|---|
| 182 | --suggest-snapshots-ok Query the Internet Archive for a snapshot of each
|
|---|
| 183 | "OK" page just to make sure it's available. Note
|
|---|
| 184 | that this will add a tremendous amount of time to
|
|---|
| 185 | the script execution because there is a rate
|
|---|
| 186 | limit to the Archive API. Note that this option
|
|---|
| 187 | does nothing unless you also use the
|
|---|
| 188 | --record-ok-links argument.
|
|---|
| 189 | --check-archive-links Check links that are already pointing to a page
|
|---|
| 190 | on the Internet Archive or archive.is (AKA
|
|---|
| 191 | archive.today). In theory these links should be
|
|---|
| 192 | totally stable and not need validation.
|
|---|
| 193 | --take-screenshots FILE Call the Google Chrome binary at this path to
|
|---|
| 194 | take screenshots of each "OK" page.
|
|---|
| 195 | --timeout NUM Wait this many seconds for a site to respond. The
|
|---|
| 196 | default is 10. Important note: Val will attempt
|
|---|
| 197 | to reach each URL three times, so the time taken
|
|---|
| 198 | to ping an unresponsive site will be three times
|
|---|
| 199 | this setting.
|
|---|
| 200 | --start-url NUM Start at this link in the links CSV file.
|
|---|
| 201 | --end-url NUM Stop at this link in the links CSV file.
|
|---|
| 202 | --upload FILE Upload report using the credentials and path
|
|---|
| 203 | given in this local text file. See sftp_login.txt
|
|---|
| 204 | for template.
|
|---|
| 205 |
|
|---|
| 206 | BUGS
|
|---|
| 207 | The script cannot properly parse any line in the external links file
|
|---|
| 208 | which contains a comma in the name of the wiki page containing a link.
|
|---|
| 209 | Commas in the link itself are not an issue.
