Question

Parameters in `\newcommand`?

Answer 1

yes

Answer 2

``\newcommand\cat[4]{^{#1}_{#2}\large\operatorname {\mathcal {UNK}}^{#3}_{#4}}
\cat abcd ~\to ~ \cat {\cat defg}{\cat hijk}{\cat lmno}{\cat pqr{\cat {\cat stuv}{\cat wxyz}{\cat \alpha\beta\gamma\delta}{\cat \epsilon\zeta \eta{\cat {\cat \theta\iota \kappa\lambda}{\cat \mu\nu o\pi}{\cat\rho\sigma\tau\upsilon }{\cat \phi\chi\psi\omega}}}}}``

\[\newcommand\cat[4]{^{#1}_{#2}\large\operatorname {\mathcal {UNK}}^{#3}_{#4}}
\cat abcd ~\to ~ \cat {\cat defg}{\cat hijk}{\cat lmno}{\cat pqr{\cat {\cat stuv}{\cat wxyz}{\cat \alpha\beta\gamma\delta}{\cat \epsilon\zeta \eta{\cat {\cat \theta\iota \kappa\lambda}{\cat \mu\nu o\pi}{\cat\rho\sigma\tau\upsilon }{\cat \phi\chi\psi\omega}}}}}\]

Answer 3

LOL wow, can you just show me how to make an operator which colors the text green and makes it gold, and then I could give parameters to it? Like a function in javascript.
```
function ranFunction(ranText) {
[insert stuff here]
}
```

and then running it on a string.
```
ranFunction("Parth");
```

Answer 4

Makes it bold*

Answer 5

`\newcommand\Parth[1]{\bf\color{green}{#1}}
500+abc+\Parth{13} =?`

\[\newcommand\Parth[1]{\bf\color{green}{#1}}
500+abc+\Parth{13} =?\]

Answer 6

Yes, that's what I wanted! What does the `#` mean? Does it act like a parameter or something?

Answer 7

after `\newcommand ` and `\Parth` (the operator name) there is a term in square brackets that is the number of variables the operator works with
the `#1` is a reference to the first variable

Answer 8

Ah, nice, we have variables in typesets too.

Answer 9

\[\newcommand\Unk[1]{\mathbf{#1}}\\ \Unk{UnkleRhaukus~rocks!}\]

Answer 10

you can leave a variable blank with `{}`

`\newcommand\intl[4]{\int\limits_{#1}^{#2}f(#3)\mathrm d#4}`
`\intl ab{}z =?`
\[\newcommand\intl[4]{\int\limits_{#1}^{#2}f(#3)\mathrm d#4}
\intl ab{}z =?\]

Answer 11

I see.

Answer 12

Thanks, gotta go. I owe you a lot. =)

Answer 13

reference for this ?

Answer 14

you can even have a newcommand without variables
`\newcommand\something[0]{ {\tiny\color{gray} ? }} \
\something`
\[\newcommand\something[0]{ {\tiny\color{gray} ? }} \
\something \]

Answer 16

maybe you really want to use

`\newenvironment` @ParthKohli

I haven't tried that command yet

Answer 17

use \(\text{\ }\boldsymbol{{boldsymbol{}}} \)

instead of just \(\bf{\text {\ bf}}\) if you dont want to loose italics

```
\newcommand\Parth[1]{\boldsymbol{\color{green}{#1}}}
\Parth{@ParthKohli}
```
\[\newcommand\Parth[1]{\boldsymbol{\color{green}{#1}}}
\Parth{@ParthKohli}\]
