This is not actively maintained, and has been left in a semi-working state of work-in-progress. Hopefully one day I'll get back to actually finishing this properly. I am just throwing this out to public, so it doesn't just sit on my computer, it's a fun plugin made in a rush during 2020 advent of code.
Vim plugin to evaluate scripts & code inline with ease!
- Easy to use - just write your shebang under your code.
- Configurable!
- Evaluate multiple chunks of code
- Evaluate output of previous code chunk in a following chunk! (* note: theres probably bugs with this)
- Code is still usable outside of vim!
Just write #!/bin/bash and run :Book to get output! ( asciinema recording explains better than thousand words!)
Just insert a shebang line without command to split the output.
#!/bin/bash
echo "Hello World!";
#!
echo "foo bar!";
#!/bin/bash
# foo bar!
" comment is the character(S) prefixing all output lines,
" to preserve the executability of the code outside of vim.
let g:book_comment='#'
" Shebang is the *nix magic, prefixed by a comment character with this as a suffix
" #!/bin/bash as an example.
let g:book_shebang='!'
" Embed output of previous chunk into the following chunk of code with this value.
" It literally replaces the inlineEmbed value with the output of previous command.
" This is a buggy feature, and possibly removed later on.
let g:book_inlineEmbed='!!'
" Don't think that this works, but is a plan to ensure that there are
" no code that just keep executing forever if configured.
let g:book_timeout='2' " don't this this currently works..
" Another planned feature of evaluating single lines of code.
let g:book_inline='#!' " this is a planned feature.
" evaluate only on change. I don't this this is implemented either,
" all code blocks are re-evaluated upon execution of :Book.
let g:book_onchange='0' "
Add this to your vimrc.
autocmd InsertLeave * :Book
take a look at this example and adjust it to your preferences!
augroup book_settings
autocmd!
autocmd BufNewFile,BufRead,Filetype *.sh let g:book_comment='#'
autocmd BufNewFile,BufRead,Filetype *.sh let g:book_shebang='!'
autocmd BufNewFile,BufRead,Filetype *.sh let g:book_inline='#!'
autocmd BufNewFile,BufRead,Filetype *.sh let g:book_inlineEmbed='!!'
autocmd BufNewFile,BufRead,Filetype *.sh let g:book_timeout='0'
autocmd BufNewFile,BufRead,Filetype *.sh let g:book_onchange='0' "only re-run on change
autocmd!
autocmd BufNewFile,BufRead,Filetype *.lua let g:book_comment='--'
autocmd BufNewFile,BufRead,Filetype *.lua let g:book_shebang='!'
autocmd BufNewFile,BufRead,Filetype *.lua let g:book_inline='--'
autocmd BufNewFile,BufRead,Filetype *.lua let g:book_inlineEmbed='!!'
autocmd BufNewFile,BufRead,Filetype *.lua let g:book_timeout='0'
autocmd BufNewFile,BufRead,Filetype *.lua let g:book_onchange='0' "only re-run on change
augroup end
Heres an example of a script I made for golang, modify it for your own usage, and add it tosomewhere in your env and refer to it in your shebang.
#!/bin/bash
#disable gomod
GO111MODULE=off
##create temp file and redirect STDIN to it
TMP=$(mktemp "/dev/shm/XXXXXXXXXXXXXXXXX.go");
while read -r line; do echo "$line" >> "$TMP"; done
shift;
#evaluate code & acquire exitcode
go run "$TMP" ${@/#/};
ec=$?;
#clear tmp
rm "$TMP"
#exit with go run exit code
exit $ec;
