A case against syntax highlighting

Tue 11-Sep-2018 06:08
I view programming from the perspective of a language. I know that this kind of view point is absurd. but that's how I view programming. I find that looking at highlighted text is a distraction for me. I also believe that allowing colored syntax to help me pick out variable and functions and comments just seems too much assistance.

However, highlighting text does have its benefits. For example: highlighting a line of text which you are trying to remember which concerning a concept or point of view. Underlining or highlighting is great for picking out main points from paragraphs. But it's not used to highlight the differences between a noun or a pronoun, or a verb from a adverb. These things need to be taught without the use of highlights.

which terminal introduced color attributes for escape sequences?

DEC's VT241?

However when modems came in to play, the terminal's UART and the host's UART were no longer directly wired to each other and modems would only transmit data and no control lines between them. This situation required another method of flow control that would have to be transmitted in-band with the data. So software flow control via device control characters was invented.

This flow-control pre-dates modems. The ^S/^Q characters _are_ the ASR-33 teletype's codes for turning off and on (respectively) the paper tape reader. Systems would issue them to prevent their processing programs from being overrun by automated input from tape. Later they were generalized into line disciplines, etc.
