@gsuberland @cstross @WellsiteGeo @quixoticgeek @owent @alicemcalicepants @nullcolaship @davidtheeviloverlord @edwinb Unicode defines word boundaries, and Perl has
\b{wb}, which matches them.@ilmari @cstross @WellsiteGeo @quixoticgeek @owent @alicemcalicepants @nullcolaship @davidtheeviloverlord @edwinb ooh good to know, thanks

@ilmari @gsuberland @WellsiteGeo @quixoticgeek @owent @alicemcalicepants @nullcolaship @davidtheeviloverlord @edwinb My perl experience mostly predates unicode
@cstross @gsuberland @WellsiteGeo @quixoticgeek @owent @alicemcalicepants @nullcolaship @davidtheeviloverlord @edwinb To be fair,
\b{…}was only added to Perl ten years ago -

@jernej__s @cstross @gsuberland @WellsiteGeo @quixoticgeek @owent @alicemcalicepants @nullcolaship @davidtheeviloverlord @edwinb yes, that's why I wrote
\b{…}, not\b. -

and vim has \< and \> for “directed” word boundary zero-width expression -
@cstross @WellsiteGeo @quixoticgeek @owent @alicemcalicepants @nullcolaship @davidtheeviloverlord @edwinb or [^\w-] instead of \W for a more careful approach, since the \W class will replace smarty-pants to smarty-trousers. hyphens are not included in \w, so the inverted class \W matches on them, which is unlikely to be what you want. [^\w-] works the same but doesn't treat hyphens as word boundaries to avoid the issue.
@gsuberland @cstross @WellsiteGeo @quixoticgeek @owent @alicemcalicepants @nullcolaship @davidtheeviloverlord @edwinb Wait, you’re telling me a word character is not the same as a not-not word character?

@adamrice @gsuberland @WellsiteGeo @quixoticgeek @owent @alicemcalicepants @nullcolaship @davidtheeviloverlord @edwinb (Obligatory Bill Clinton joke): It depends what you mean by "word".
Less flippantly: is 467130356 a word? Is 17/4/2012 a word? Is !true a word?

@gsuberland @cstross @WellsiteGeo @quixoticgeek @owent @alicemcalicepants @nullcolaship @davidtheeviloverlord @edwinb gonna be blunt: you want to eyeball and confirm every substitution if possible
these days you can be told how many potential ones up front for a lot of text pretty fast

Character name changes. If for some reason you change the name of a character you *really* need to double-check that it's changed *everywhere*. Hint: regular expressions and global *conditional* search/replace are your tools. Also how to manage word stemming with regexps. Then triple-check *everything*. Otherwise—guaranteed—you'll flip a character's name in one paragraph and the internet will never let you forget it!
@cstross
I would also recommend doing it interactively.
Yes you need to confirm every change but you learn where your regex goes wrong
Sadly this doesn't help with missed occurrence -
@DJRNDM @owent @alicemcalicepants @nullcolaship @davidtheeviloverlord
Groan.
s/(\W+?)(pants)(\W+?)/\1trousers\3/ig
You could use \b — match a word boundary — instead of \W+? (smallest count of non-word characters preceding the next regexp group) but that'd miss run-on strings ending in pants (eg. InterCappedpants).
The pcre search modifiers s///ig are for case-insensitive and global.
@cstross @DJRNDM @owent @alicemcalicepants @nullcolaship @davidtheeviloverlord
This is still not perfect. You would need to make sure every substitution is the correct meaning of ‘pants’. Otherwise you risk sentences like:
“Whew! I'm all out of breath after that steep hill,” he trousers.

I once changed a character's name from Allan to Ben, and later changed it back.
Reading through the manuscript, I found I had thus invented the Allanch seat.
@davidtheeviloverlord @cstross I recall a story where one of the characters was pulling up his Brendas. I guess Jean got renamed...

@headword @cstross @owent @alicemcalicepants @nullcolaship @davidtheeviloverlord Hot damn! Totally forgot for a moment there that verb existed.
