[TxMt] Re: snippet that replaces the current word

[Timothy Bates]

Dear all,

Looking some more into this, the new environment variables for italic,  
bold, and underline markup are imported into commands in the ENV[]  
array, so that makes building those commands more generic. So far so  
good.

My roadblock now is that to get  the format commands to act as toggles  
(i.e. they remove or add markup as appropriate), the "word"  
environment variable should let the formatting though, but it doesn't,  
(so '*bold*' comes in as 'bold').

Before I reinvent the wheel, does anyone have code to use the  
"TM_LINE_INDEX" to parse "TM_CURRENT_LINE", extracting the current  
word plus markers such as "TM_BOLD_MARKER" on either side if present?

My stumbling block is writing a regex to find the "TM_CURRENT_WORD"  
but only when it is at the  "TM_LINE_INDEX" location (to avoid making  
mistakes when a line contains multiple copies of the current word).
