In addition to my experiments with the design of this site, I was also testing out BBEdit as my main writing and programming tool. BBEdit didn’t stick, but I did like some of the scripting the good Dr. Drang has done, and wanted to adopt a few for MacVim. I started with three of his scripts today, one to paste and select text in one command, one to convert a tab-separated table to Markdown, and another to even up the Markdown table so it’s easier to read in plain text.
Since Dr. Drang’s scripts read from stdin and output to stdout1, converting them to Vim was very easy, once I found the right syntax for my vimrc file2. My first thought was that I would be able to copy the same syntax I use for calling the outstanding formd by Seth Brown, but formd is meant to parse the entire text of the file, not just the selection. Eventually, I found my answer on StackOverflow.
My vimrc file now has the following lines:
" Even up a markdown table vmap <leader>mn <esc>:'<,'>!~/Unix/bin/Normalize-Tables.py<CR> " Convert a tab separated tabel to a markdown table vmap <leader>mt <esc>:'<,'>!~/Unix/bin/Tabs-to-Markdown-Tables.pl<CR>
The first word,
vmap, maps the shortcut to visual selections in Vim. Next,
<leader>mn creates the shortcuts
,mn for Normalize-Tables.py and
,mt for Tabs-to-Markdown-Tables.pl.
The next part
<esc>:'<,'> grabs the selection and passes it to the command, which starts with an exclamation point3 and ends with
<CR>, which stands for “Carriage Return”.
I need to spend some time in my vimrc file to sort out the naming convention for all the key maps, but for now, I’m thinking “,mn” for “markdown normalize”, and “,mt” for “markdown from tabs”.
For the third part I’m borrowing from Dr. Drang, I wanted to paste and select text at the same time. Once again I had to turn to StackOverflow, and now have this mapped in vimrc:
nnoremap <leader>sp :set paste<CR>:put *<CR>:set nopaste<CR> <Bar> `[v`]
The first part sets the mapping,
,sp, which I’m thinking of as “select paste”, and then pastes the text from the OS X system clipboard. Next, the
<Bar> entry strings two mappings together in Vim. Finally,
\[v`]` performs the selection on the last change to the text.
So, now I can take text from Excel like this:
Left align Center align Right align This This This column column column will will will be be be left center right aligned aligned aligned
paste and select it with
,sp, followed by
,mt to convert the table to Markdown.
|Left align|Center align|Right align| |--|--|--| |This|This|This| |column|column|column| |will|will|will| |be|be|be| |left|center|right |aligned|aligned|aligned|
,mn to even the table up nicely:
| Left align | Center align | Right align | |:-----------|:------------|:-------------| | This | This | This | | column | column | column | | will | will | will | | be | be | be | | left | center | right | | aligned | aligned | aligned |
As always, my thanks to the good Doctor for scripts and inspiration.
