Work in progress, if you encounter any issues regarding installation or understanding what this is all about, please send an email to contact@martinlemaire.fr or open an issue here and i'll be happy to answer

A browsable webpage generated from a textual database you might want to use as a browser homepage. You can edit the database by editing the file called BOOKMARKS or by running the provided script called edit_bookmarks_dmenu.sh (requires dmenu). The script can be ran from the command line but I suggest to bind it to a keystroke combination.

If you want to try with an example BOOKMARKS database (32kb) :

curl -O https://martinlemaire.fr/signet.sh/BOOKMARKS

then

git clone https://git.vvvvvvaria.org/clemtre/signet.sh.git
chmod +x signet.sh
./signet.sh

It produces the following html document :

index.html a browsable bookmark manager A sample of its corresponding textual database, in the form of blankline separated records with key/value fields :

BOOKMARKS

Name: HEX (Unifont) - Just Solve the File Format Problem
Description: 
Tags: bbb, hex

Given this database, signet will color the first link in pink and hide the last one because of its "hide" tag.

Presentation

signet.sh

Signet.sh is a shell script parsing a bookmark database to a webpage. It uses awk inside a here-doc declaration redirected to an html file.

I have created this script because I found the bookmarks manager from firefox not great to use, to the point where I did not have the habit to bookmark my browsing journeys. Firefox stores bookmarks in a sqlite which is not human readable. Although it allows an export in json and html, I wanted something text based and personal.

Bookmarks database format

Only a Url is required, the rest of the fields are optional :

  • URL : the url pasted from the clipboard (exits if no url given)
  • Name : grabs from the bookmarked page with curl
  • Description : a description from the user
  • Tags : comma separated keywords
  • Date : posix time of the bookmarked link
  • Color : css color (name, hex, rgb etc...)

index.html structure

# Usage ## Add a bookmark :

To add a link, I select the URL of the page with Ctrl + l, then copy to clipboard and run add.sh with Super + i.

If anyone knows how to retrieve the url of the current browser page without having to copy it and send it to clipboard, this would save two steps out of three.

In short : Ctrl + l, Ctrl + c, Super + i

(or shorter : Ctrl + l + c, Super + i)

Super + i because in my window manager (awesomewm) configuration file located in ~/.config/awesome/rc.lua, I have the following lines:

awful.key({modkey}, "i", function()
awful.util.spawn_with_shell("add.sh") end, 
{description = "Sends the link in clipboard to add.sh"}),

Edit a bookmark :

Use your text editor of choice. Open the BOOKMARKS file and edit the entry. The last entry is at the bottom.

If you use vim, with BOOKMARKS opened you can press in normal mode m + B and it will save a mark to the file you can then access with ' + B

Installation

Works on my machine : Ubuntu 20 LTS, it should work on any POSIX compliant machine, macOS, linux* or bsd*. I'm curious to know how it goes on windows :^)

clone the repo

git clone https://git.vvvvvvaria.org/clemtre/signet.sh.git
cd signet.sh

Dependency :

To add a link via the proposed interface, we will need to install dmenu and htmlq.

dmenu

Dmenu is an interactive menu that allows us to select and write values in a menu. These values can come from a program provided as input from a pipe "|", for example:

ls | dmenu

displays a drop-down menu with the files in my directory. In our script, to store the given tags in a variable, we can do:

tags=$(echo "" | dmenu -p "Enter comma-separated tags:")

install dmenu :

https://askubuntu.com/questions/828450/how-to-install-dmenu

htmlq

Htmlq is an HTML parser written in Go. It doesn't matter which parser we use, it seems that each language has its own. We give to the program an html string and it filters through it using css selectors returning the found html elements Using javascript, retrieving all the <h1> children of a <section> can be done with :

document.querySelectorAll('section h1')

In shell, it's more complicated since we don't have document object model we can query. Htmlq is made for that:

cat fichier.html | htmlq 'section h1'

And to output only the text -- the javascript equivalent of .innerHTML:

cat fichier.html | htmlq 'section h1' --text

We use it to retrieve the title tag of the page to add:

curl page.html | htmlq 'title' --text

Pre-release patch:

curl $url | awk -v RS='</title>' \
    '/<title>/ {gsub(/.*<title>/, ""); print}' |\
    tr -d '\n'

For the moment this step is blocking. In case internet cuts while bookmarking a link, you will have to wait for the end of the curl attempt to move to the next field in the script :/ sorry!

Repository structure :

  • BOOKMARKS → A textual database of bookmarks
  • edit_bookmarks_dmenu.sh → A script to add a link to the database using dmenu
    • dmenu
    • ./signet.sh
  • bookmark.sh → The shell script itself
    • It generates a new html page from the link database (default index.html)
  • style.css → Stylesheet for index.html
  • script.js → A bit of javascript for:
    • search in the <textarea>
    • add background colors to entries that have them
    • if the description field is empty, do not display it
    • format posix time dates to YY-MM-DD format

/!\ Soon /!\

starred.sh → curl from the github user api and format it in the same way as signet.sh without using jq https://api.github.com/users/[user]/starred
