>>25 not 2 but eh. I use sam and acme enough to have opinions. The question I would have about plan9port versions is if they would actually work well.
some things to test. type some text into the text box. repeat the same word a few times in the text. then use the right mouse button to click one instance of a word. does it take you to the next instance of it?
next in the blue menu box, add a new line and type | tr 'a-z' 'A-Z'
that's a unixy pipe the translate program and options to change from lower to upper case
then use the mouse to highlight some text with left click. then once the text to change is selected use the middle mouse button to highlight the pipe command and release the middle mouse button. did the highlighted text change to upper case?
next add a bash script in your path ie something like $USER/bin that does something simple like echo some string. and make sure it's executable. next type | yourbashcommand
with your cursor in the place in the text box that you want the output middle highlight the command with the pipe does the output of the program show up in the text box?
and penultimately. outside of acme copy some text into your buffer, then in acme, chord left and right mouse buttons into a text box. does it paste? and lastly chord left and middle on some text in your acme. this should make the text disappear which was highlighted. then let go of middle and add right button (same paste chord we did before but without letting go of left button) to put the text back. go outside of acme to some other linux text box and paste as normal. did linuxs paste buffer get updated to acme's?
if it does all this i'd say that's the bare minimum to be useable.
also you now know a lot of what makes acme pretty nice. | takes the selected text and uses it as stdin for a command which is executed with middle click so extending acme is very easy for most.
and in the style of steve jobs. One more thing is the 'win' command. (just type win anywhere in acme then middle click it) this opens your shell in an acme window.
i did not mean to sent that twice...
