Commands

Following the commands and how to use them is explained based on examples.

Create a website

A website is send to syclink with the global -w flag. If the website does not exist yet the user is asked whether to create it and whether to set it as the default website. This is done with commands that require a website to operate on.

$ syclink -w my-new-website add link "http://example.com"

Before the command add link is executed the website is created. In this case a website called 'my-new-website' is created in the default directory at `~/.syc/syclink/websites/my-new-website.website

If an existing website is specified by the -w command and it is different to the default command, the user is asked whether to set the selected website as the default one.

Commands that require a website are add, update, delete, list, find, merge, import, export and website create.

If no website is specified the default website is used.

Link Commands

Add a link

A link may have a title, a description and a tag. Title, description and tag are optional but a link obviously has to be provided. If no title is given the link is used as the title.

$ syclink add link --title "Test page" --tag TEST \
                   --description 'For testing purposes' http://example.com 

It is also possible to add links from a file

$ syclink add file file-with-links

Update a link

To update a link the URL has to be specified. If more than one link has the same URL only the first link is updated.

$ syclink update link --title "Example" http://example.com 

It is also possible to update links with links saved to a file

$ syclink update file file-with-links

If many links have to be updated they can be exported to a csv file. Then the changes are made in the csv file and finally the update command is called.

$ syclink export csv > exported-links
edit the links
$ syclink update file exported-links

Delete a Link

To delete one or more links the URLs have to be provided.

$ syclink delete link http://example.com http://challenge.com

It is also possible to delete links based on URLs saved in a file. Asume we have a file urls with following content

http://example.com
http://challenge.com

Then we can delete the links with the URLs stored in the urls file with

$ syclink delete file urls

List links

Links can be selected based on a filter. If no filter is given all links are listed. It is possible to specify the columns to print. Possible columns are url, name, description and tag.

$ syclink list --tag TEST --columns 'url,description'

url                | description
-------------------+---------------------
http://example.com | For testing purposes

The is a switch --expand and a flag --width. If no width is specified list will print the complete content and probably mess up the table. With a width specified the the columns are scaled so the overall width of the table will be the size of width specified. The expand switch will expand the table to the specified width if the table would be smaller than width.

$ syclink list --tag TEST --columns `url,description` --width 70 --expand

Find links

It is also possible to search for links based on a search string. The find command searches all attributes of the links and is searching for the occurance of the search string within the attributes. So the search does not list exact matches only.

$ syclink find --columns 'url,tag' 'example' 

url                | tag
-------------------+-----
http://example.com | TEST

The --expand switch and the --width flag are also available with the find command. Details see at List links.

Merge Links

If there are multiple links with the same URL, these links can be merged. During a merge the first link found will be updated with the join of the values of the other links.

$ syclink add link --tag "Day" --name "Work" --description "Busy time" \
                   http://example.com
$ syclink add link --tag "Night" --name "Fun" --description "Fun time" \
                   http://example.com
$ syclink merge 
$ syclink list

url                | name      | description        | tag
-------------------|-----------|--------------------|---------
http://example.com | Day,Night | Busy time,Fun time | Work,Fun

Import Commands

Bookmarks can be imported from Mozilla Firefox, Google Chrome, Internet Explorer and from directories.

The command is syclink import followed by a sub-command indicating from which web browser to import, or from which directory.

In case of importing from Internet Explorer and from a directory the parent directories are used as tags beginning below the path to the Internet Explorer directory or the standard directory. To control to which level the directory should be used a level switch can be used.

$ syclink import dir --level 2

will only use two parent directories as tags. It is also possible to specify tags to use during import. In this case if level is 1 and also 1 tag is specified this tag is the only tag used.

$ syclink import dir --level 1 --tags Books PATH/TO/BOOKS

If the level is greater than tags specified the difference between tags specified and levels is the number of parent directories added as tags

$ syclink import dir --level 2 --tags Books PATH/TO/BOOKS

If there is a file in PATH/TO/BOOKS/RUBY then Books and RUBY is used as tags.

Firefox

Firefox stores its bookmarks in a SQLite3 database called places.sqlite. With Ubuntu this database is usually located in

'~/.mozilla/firefox/*.default/places.sqlite'. 

If you are on Windows the file is located in the user's home directory

'~/AppData/Roaming/Mozilla/Profiles/*.default/places.sqlite'.

The bookmarks on Ubuntu can be imported with

$ syclink import mf ~/.mozilla/SOME_CRYPTIC_NAME.default/places.sqlite

Chrome

Google Chrome stores its bookmarks in a JSON file called Bookmarks. With Ubuntu this file is usually located in

'~/.config/chromium/Default/Bookmarks'. 

If you are on Windows the file is located in the user's home directory

'~/AppData/Local/Google/Chrome/User Data/Bookmarks'.

The bookmarks on Ubuntu can be imported with

$ syclink import gc ~/.config/chromium/Default/Bookmarks

Internet Explorer

Internet Explorer stores its bookmarks in a directory structure. The bookmarks are located in the user's home directory

'~/AppData/Favorites'

The bookmarks (of course on Windows) can be imported with

$ syclink import ie ~/Appdata/Favorites

Directory

The PATH_TO_DIRECTORY can have patterns that allows to import specific files.

Examples:

PATH_TO_DIRECTORY/**/*.pdf 

will import all pdf-files in the directories and sub-directory

PATH_TO_DIRECTORY/**/* 

will import all files in the specified directory and sub-directories

To import all files from some-directory call

$ syclink import dir ~/some-directory/**/*

If on Windows and the directory contains .URL-files the URL within the .URL-file will be used as the link target.

Export Commands

If links have to be changed in a buld then it is easier to do so in a file and when done updating the links from the file.

The links can be exported with

$ syclink export csv

This will print to the standard output. To save it to a file can be done as follows

$ syclink export csv > my-links

Now we can edit the links in the file and when done updating them like so

$ sylinks update file my-links

Website Commands

Show websites

The websites are saved to ~/.syc/syclink/websites/ and the html representations are saved to ~/.syc/syclink/html/. When listing websites both webstites and html files are listed.

The following command will list all websites indicating the default website

$ syclink website show
[default] ~/.syc/syclink/website/one.website
          ~/.syc/syclink/website/two.website

To list websites based on a search string the search string has to be send to the show command

$ syclink website show "example"

If the --exact switch is given the command is listing exact matches of the search string only

$ syclink website find -e "http://example.com"

Check websites

The website check command checks the availability of the urls and files. The result can be printed to the STDOUT in a table format or as CSV.

$ syclink website check --table --width 70 --available --unavailable

Available URLs or Files show a response "200" and unavailable show "Error". It is also possible to choose upon the columns to print. Available columns are url and response. If no columns flag is provided both columns are printed.

$ syclink website check --columns "url,response" --table

Remove websites

Websites and their html representations can be deleted based on a filter string. To delete all websites and respective html representation the filter string '*' can be provided

$ syclink website remove "*"

About to delete:

Websites
--------
/home/user/.syc/syclink/website/example.website

HTML-Files
----------
/home/user/.syc/syclink/html/example.html

Delete websites and corresponding html files (y/n)? 

Other exmamples of filter strings are *mple which will find example as well as ex*.

Make a html representation of the website

The ultimate command is website create which will create the html representation of the website.

The html file is created based on an erb file located in ~/.syc/syclink/templates/syclink.html.erb. This can be adjusted to your convenience. The methods that can be used can be looked up in lib/syctask/website.rb.

The html file will search for a css file in the directory stylesheets which is relative to the html file. The stylesheet is named styles.css. It is possible to change it or replace it entirely. If the stylesheet's name is changed this also has to be done in ~/.syc/syclink/templates/syclink.html.erb.

There is also a scss file which needs to be compiled to css with sass like so

$ sass ~/.syc/syclink/html/stylesheets/styles.css.scss:\
  ~/.syc/syclink/html/stylesheets/styles.css

Warning: If the css file has been changed all changes will be overridden by sass.

Workflow

To create a website the steps are as follows

• add links to a website
• create the html representation

Following is showing the above sequence in commands

$ syclink -w example add link "http://example.com" --tag EXAMPLE
$ syclink add link "http://github.com" --tag DEVELOPMENT
$ syclink website create
