Command prefixing for continuous workflow using a single tool.

with

Program prefixing for continuous workflow using a single tool.

Usage

with <program>

Starts an interactive shell with where every command is prefixed using <program>.

For example:

$ with git
git> add .
git> commit -a -m "Commited"
git> push

Can also be used for compound commands.

$ with java Primes
java Primes> 1
2
java Primes> 4
7

And to repeat commands:

$ with gcc -o output input.c
gcc -o -output input.c>
<enter>
Compiling...
gcc -o -output input.c>

To execute a shell command proper prefix line with :.

git> :ls

You can also drop, add, and replace different commands.

git> +add
git add> <some file>
git add> !commit
git commit> <arguments and message>
git commit> -
git>

To exit use either :q or :exit.

with's Issues

Add support for shell syntax in `:`-prefixed lines

> : echo 1 | cat
1 | cat
> : echo 1 && echo 2
1 && echo 2

Expected output:

> : echo 1 | cat
1
> : echo 1 && echo 2
1
2

sed -r not supported on on osx

Running with gives

sed: illegal option -- r
usage: sed script [-Ealn] [-i extension] [file ...]
       sed [-Ealn] [-i extension] [-e script] ... [-f script_file] ... [file ...]

Include tests

Using appveyor and/or travis.

Syntax error: "(" unexpected (expecting "fi")

I downloaded the script, run it on my Ubuntu 16.04 laptop and get

$ with ls
/home/ulysses/bin/with: 12: /home/ulysses/bin/with: Syntax error: "(" unexpected (expecting "fi")

Correct readme

Readme says states that ':q' or ':exit:' will exit

Entering git> :exit: command gives error but git> :exit works?

Doesn't work with aliases

Wildcards are expanded when nesting withs

Example:

▶ with grep
grep> +foo *
grep foo LICENSE.txt README.md with>

sed: 1: "s/%prefix%/curl -vvv ht ...": bad flag in substitute command: '/'

When use with programs with slashes in their parameters. Something like with curl 'https://google.com'

Repository does not include license information

Port to windows batch script

colours get lost

with with ls i don't see the coloured folders. it'd be nice to somehow retain the colouring.

Syntax error on Linux Ubuntu with #!/usr/bin/env sh

Hi, on Ubuntu 14.04 LTS when I try to use with I obtain the following syntax error:
with: 12: with: Syntax error: "(" unexpected (expecting "fi")
If I try to replace #!/usr/bin/env sh with #!/usr/bin/env bash all the troubles go away.
I think I obtain that error because on Ubuntu sh is a link to dash shell.

Allow for adding and dropping commands.

For example:

git> +add
git add> -
git>

with --help: print_help command not found

The -h/--help flag is broken:

$ with -h
/usr/bin/with: line 46: print_help: command not found
error: "-h" is not a valid executable

Looking at the source, I believe that line 46 should be calling print_usage and/or print_options, not print_help (which doesn't exist).

Installation with zsh

Hello,
This tool seems awesome but I can't install it on zsh. Can you help me with that?

Port script to POSIX sh

As mentioned in #15

Run shell check with environment set to sh for specifics on what needs to go.

Include full command in shell history

Pretty straight forward.
javac> Utility.java

Should go into main history as:
javac Utility.java

Error when using sh. Script should use Bash by default.

Bash works fine, using sh does not.

/usr/bin/with: 12: /usr/bin/with: Syntax error: "(" unexpected (expecting "fi")

Configure for windows bash

Bash has different absolute paths for things like tmp and completion. Fixing this would entail finding out if we are in linux bash or windows bash...now sure how this is possible for now.

Shellcheck

Please use https://github.com/koalaman/shellcheck on this script. It points some nasty things like:

In with line 35:
          ${prefix[@]} ;;
          ^-- SC2068: Double quote array expansions to avoid re-splitting elements.
          ^-- SC2039: In POSIX sh, array references are undefined.

It's just the single warning, full list have more than 10 of them.

Retain prompt or allow user prompt

@joaquin-v has a PR for this. I think this warrants some discussion though.

Access to shell completions.

Been trying to do this for a while to no avail.

http://stackoverflow.com/questions/4726695/bash-and-readline-tab-completion-in-a-user-input-loop

doesn't quit with ^D, ^C cancels process instead of current line

Currently ^D will send the current line if it's not-empty, but when used on an empty line it prints the prompt right after the current.

^C seems to always quit the with prompt rather than starting a new prompt line.

I'm not sure if this is desired/intended behavior, but in my experience most/all interactive shells seem to respond this way.

Program not installed

On my Debian 8.6, with would not work on any program, giving the error: Program is not installed message. This happened on both bash and fish shells.

It seems that you missed a "$@" in the last line, and parameters are not passed to your script.

I changed the last line from main to main "$@" and things started working again. I am not sure if there are side-effects, as a result I posted this as an issue so more people could help.
