bin

A collection of useful scripts. Each script is summarised below.

Tip: Some of my scripts use "nix-shell shebangs". You wont need that if youre not using Nix (or you install the pre-requisite packages globally). So if the script begins with

#!/usr/bin/env nix-shell
#! nix-shell -i bash -p blah blah blah

You can replace that with

#!/usr/bin/sh

all-history

Display bash history for all sessions. I keep a separate history file for each bash session.

amy-bib

Read BibTeX information from paste buffer and put it into my citation management system. I keep each BibTeX in a separate file. The name of the file is the BibTeX key.

amy-bib-gen

Read all BibTeX entries from my citation management system, creating a single BibTex file.

amy-prompt.hs

A work in progress; not currently in use.

Set the colour of the bash prompt according to the current directory. The colour is chosen based on a checksum of the filepath. The algorithm usually results in a visually distinct colour for each path. To use this script, put the following line in your shell configuration file (e.g., .bashrc).

source amy-prompt.sh

amys-launcher

Themed launcher

amy-status

Experiment with yambar. Not currently in use.

check-permissions

Debug file permisions

clean-bib

Clean all ".bib" files in the current directory, previewing each change before it is made.

clear-nixos-locks

You shouldn't need this. I once thought I needed it, but I didn't.

copyWithRef

Copies text with some info about where it came from.

count-files

count-files [PATH].. reports the number of files in each PATH, including any hidden files and subdirectories. The directories themselves are also counted.

Tip: Because of the way glob patterns work, count-files * will ignore any hidden files in the current directory. One workaround is count-files .??* *

doi2bib

Fetch the BibTeX information for a DOI.

Example:

doi2bib 10.1162/artl_a_00074

Requirements: curl

duplicated-haskell-code

A script to find common code between all pairs of Haskell files in the current directory.

dw

Sets up, verifies, and maintains links for dotfiles. For each file listed in ${CONFIG_FILE}, this script will:

If the file does not exist, link it to the corresponding file in ${DOTFILE_DIR}.
If the file exists and is not a link, move it to ${DOTFILE_DIR} and replace it with a symbolic link.
If the file exists and is a link, make sure it's linked to the corresponding file in ${DOTFILE_DIR}.

This script is idempotent, so you can use it to set up links for the first time on a new machine, put additional files under dotfile management (add them to ${CONFIG_FILE} first), or simply verify that existing links are correct.

fix-copyright.sh

Update the copyright date for all Haskell files in and under the current directory. You will see a preview of all changes before they are made.

fixit.sh

A template for making a change to a group of files, previewing each change before it is made.

format-zpl

Format text for printing to a label printer using ZPL.

gen-base16-scheme.py

Generate a colour scheme using the "base16" architecture (see http://www.chriskempson.com/projects/base16/).

Examples:

gen-base16-scheme.py ff00ff
gen-base16-scheme.py D3E067

Note that the colour you supply may be slightly adjusted by rounding.

git-summary

git-summary - summarize git repos at some path

Ex: git-summary ~

Forked from https://github.com/lordadamson/git-summary. Freely distributed under the MIT license. 2018@MirkoLedda

graphviz.py

Pandoc filter to process code blocks with class "graphviz" into graphviz-generated images. Needs pygraphviz.

grimify

haskell-same

A quick script to find common code between two Haskell files.

Usage:

haskell-same FILE1 FILE2

haskell-sanity

Check various things for Haskell development.

head-tail

head-tail n k returns the first n rows and the last k rows. Useful, for example, when you want the header of a file plus the ending.

htmlify

Replaces all line endings with HTML break tags.

key-help

Display my current key bindings

keyhelp

Display my current key bindings

logic2tex

Convert a logic sentence using unicode characters to Tex (LaTeX)

ls-theme-demo

Demo of the colour scheme currently used by ls. You might use this, for example, if you want to test different themes.

make-readme

Creates this file (README.md).

nix-init-haskell

Set up a directory for Nix+Hskell development.

pdf2doi

Extract the DOI from a PDF.

Usage:

pdf2doi [filename]

If no filename is specified, read from stdin.

Requirements: pdfinfo (install poppler_utils), pdftotext (install xpdf or python's pdftotext).

pdf2isbn

Extract the ISBN from a PDF.

Usage:

pdf2doi [filename]

If no filename is specified, read from stdin.

Requirements: pdfinfo (install poppler_utils), pdftotext (install xpdf or python's pdftotext).

preview-themes

Generate previews of all defined colour schemes.

rename-pdf

Renames a PDF file according to author and title.

same

A quick script to find common sections between two files.

Usage:

same [OPTION] FILE1 FILE2

Most options that work with "diff" should also work with "same"

set-theme

Change colour scheme for supported apps.

snippy

Select snippets of text (including code) and paste them wherever.

sway-tree-switcher

Opens an FZF window containing all windows across all environments. Focuses the window (switching workpace if required) on selection.

sync-transform.sh

A template for a script that synchronises two directories, except that instead of copying files it performs some sort of transformation.

tex2png.py

Pandoc filter to convert code blocks with class "tex2png" into images. Requires tex2png.sh.

tex2png.sh

Converts a (La)Tex document to PNG. You might use this, for example, if you want to display a short LaTeX document as an image within an HTML page.

Usage example:

   tex2png.sh sample.png < sample.tex

Your document should use the standalone document class and set convert=true. You may wish to override the default margins. Here's a sample minimal LaTeX document that you can use as a starting point.

  \documentclass[convert=true,margin=4pt]{standalone}
  \begin{document}
  \huge
  Hello world!
  \end{document}

we

A wrapper for my favourite editor.

whe

A quick script to load all of the Haskell source files and configuration files in the current project into emacs.
