🐟 Fishing

A set of functions for the Friendly Interactive Shell (fish). This is mainly made for a programmer in Haskell and Python, so it has some programs to make the Haskell stack and Python shell more convenient.

List of functions

• author: prefix the given file names with the name of the author;
• backup: make readonly timestamped copies of the list of parameters;
• biblespeak: speak the next verse of the Bible;
• dated: add the timestamp as a prefix of the given files;
• edithaskell: will run the editor with the .cabal file(s) and the .hs files in the src/ directory;
• from: initializes the python shell with from …, so from datetime import date for example can be written in the shell as first Python command;
• fromtemplate: copies the file from the templates/ subdirectory into the pwd, add it to git (if applicable), and starts editing;
• frmclip: copy from the clipboard to the stdout;
• fundo: desugar a do expression of Haskell;
• fundjinn: generate a function implementation from a signature with Djinn;
• funtype: determine the type of a Haskell expression;
• gitc: make a git commit (short for git commit -am);
• gitd: calculate the git difference and work with a pager to read the full response;
• gitmaster: checkout the master branch (and stash work in progress if any);
• gitmastertag: checkout the mater branch, pull from remote, tag the commit and push the tag to the repository;
• gitp: pushes the changes to the remote repository (short for git push);
• gitremote: add the remote as origin with the given GIT_PREFIX and the name of the directory as git project;
• gits: prints the status of the current Git repository (short for git status);
• gitu: pull the changes from the remote repository (short for git pull);
• here_is_the_news: beeps a few times to mark a certain event;
• hlint: run Haskell lint and use a pager for the results;
• igrep: run grep in a case insensitive way;
• import: initializes the python shell with import …, so import datetime for example can be written in the shell as first Python command;
• lessr: run less but allow to render ANSI terminal directives like color, etc.
• numpy: start a Python shell with numpy imported;
• pandas: start a Python shell with numpy and pandas imported;
• pointfree: determine the pointfree version of a Haskell expression;
• pomodoro: a tool to use the pomodoro technique for work and pause;
• python3: overrides normal Python prompt with an IPython shell without banner, no confirmations and matplotlib;
• redo: redo a command until the exit code is 0;
• rmemptydir: remove empty directories;
• setvar: check if a variable with the name exists; if not, query for a value;
• shlint: download the latest version of Haskell lint and run this version;
• stackb: build the haskell stack project with all warnings enabled;
• stackbench: to run benchmarks on the haskell stack project, and write the results to a file named benchmarks.html;
• stackd: build the documentation of the Haskell stack project;
• stackg: run a ghci session for the given Haskell stack project;
• stackr: run the program, this is an alias of stack run;
• stackt: test the Haskell stack project;
• stacktcov: test the Haskell project, and keep track of the coverage;
• swapfiles: swap two or more files by renaming the second to the first, the third to the second, and the first to the last;
• task: wrapper for /usr/bin/task, except that it reports tasks after the modification;
• taskd: set the task with the given id as done;
• vimc: create a directory if the directory does not yet exists before running vim;
• vimp: use vim with different tabs, a shortcut for vim -p;
• vimpsrc: open all the Haskell files in the src directory with vim;
• waitfor: takes an argument and waits that amount of time with a countdown; and
• whatday: write the date in a color of the week.

Variables

• COFFEE_MAX: end time of the day when coffee is no longer allowed, for example 1900;
• COFFEE_MIN: start time of the day when coffee is allowed in decimal notation, for example 0800;
• GIT_BRANCH: the default branch, used to automatically map the remote to the local default branch in gitremote;
• GIT_REPO_PREFIX: the prefix of (most) git repositories, for example github:hapytex; and
• USER_SLUG: the slug used to prepend to file names when adding an author to it, for example Elon_Musk.

Installation

One can install this by downloading (or cloning) and put the files in the ~/.config/fish/functions/ directory.

You can of course also clone this repository at that location and thus pull new changes directly to the configuration directory:

git clone github.com/hapytex/fishing.git ~/.config/fish/functions/
