Topology diagrams (labelled edges)
What is the best way to create diagrams like these in LaTeX? Is Tikz the way to go?
(Code for these specific instances would be useful but is not absolutely required, since I'll be needing to make diagrams similar in spirit but not identical. Also, this has almost certainly been asked before, so I would equally appreciate a link to a previous asking -- I'm just unsure what terms to search to find such a post.)
edit: looked at some old code and came up with
begin{tikzpicture}
draw[ultra thick,domain=0:1,samples=100, postaction={decorate}, decoration={markings, mark=at position 0.5 with {arrow{stealth}}}] (0,1) -- (0,0);
draw[ultra thick,domain=0:1,samples=100, postaction={decorate}, decoration={markings, mark=at position 0.5 with {arrow{stealth}}}] (1,1) -- (0,1);
draw[ultra thick,domain=0:1,samples=100, postaction={decorate}, decoration={markings, mark=at position 0.5 with {arrow{stealth}}}] (1,0) -- (1,1);
draw[ultra thick,domain=0:1,samples=100, postaction={decorate}, decoration={markings, mark=at position 0.5 with {arrow{stealth}}}] (0,0) -- (1,0);
node at (.5,-.2) {$a$};
end{tikzpicture}
although this seems rather clunky.

What have you tried?

I thought about doing something with tikzpicture and explicitly stating the parametrization of each length but it seems that there ought to be a more elegant way to do it.

@HenriMenke Well, everyone can rename these things as they wish. I do not think this is a fair criticism. And if you really feel you need to make this comment, make it here, where this notation has been proposed. This answer got 69 upvotes without anyone complaining about the notation.

You can place nodes on a path which should simplify the node positioning a lot. You might also want to factor out the arrow business into a style
.
documentclass{article}
usepackage{tikz}
usetikzlibrary{decorations.markings}
begin{document}
begin{tikzpicture}[
arrow inside/.style = {
postaction={decorate},
decoration={markings, mark=at position 0.5 with {arrow{stealth}}}
}
]
draw[arrow inside] (0,0) -- node [below] {$a$} (1,0);
draw[arrow inside] (0,1) -- node [above] {$a$} (1,1);
draw[arrow inside] (0,0) -- node [left] {$b$} (0,1);
draw[arrow inside] (1,0) -- node [left] {$b$} (1,1);

A PSTricks solution just for fun purposes.
documentclass[pstricks,12pt]{standalone}
usepackage{pstricks-add}
begin{document}
pspicture[arrowinset=0,arrowscale=2](-4,-4)(4,4)
curvepnodes[plotpoints=5]{0}{360}{3.5 t 45 add PtoC}{I}
foreach i/l/a in {0/a/<,1/b/<,2/a/>,3/b/>}{%
pcline[ArrowInside=-a](Ii)(Ithenumexpri+1)nbput{$l$}}
endpspicture
pspicture[arrowinset=0,arrowscale=2](-4,-4)(4,4)
pnode(0,0){O}
curvepnodes[plotpoints=5]{0}{360}{3.5 t 135 add PtoC}{I}
foreach i/l in {0/a,1/b,2/a,3/b}{%
qdisk([nodesep=3.5,angle=-45]{Ii}O){2pt}
psarc{->}(0,0){3.5}{(Ii)}{(Ithenumexpri+1)}
uput{8pt}[{(Ii)}](>Ii){$l$}}
endpspicture
end{document}
Note: ArrowInside

. I don't know why.

Another alternative approach using Metapost. Compile this one with lualatex
.

begin{mplibcode}
beginfig(1);
path S, C;
S = unitsquare shifted -(1/2, 1/2) scaled 100;
C = fullcircle scaled 84 rotated 16 shifted 140 right;
interim ahangle := 30; % slimmer arrows...
drawarrow subpath(0, 5/8) of S;
drawarrow subpath(5/8, 13/8) of S;
drawarrow subpath(4, 4-5/8) of S;
drawarrow subpath(4-5/8, 4-13/8) of S;
draw subpath(13/8, 4-13/8) of S;
label.top("$a$", point 1/2 of S);
label.top("$a$", point 5/2 of S);
label.lft("$b$", point 3/2 of S);
label.lft("$b$", point 7/2 of S);
for t=0 upto 3:
drawarrow subpath 2(t, t+1) of C;
drawdot point 2t+3/4 of C withpen pencircle scaled 3;
label(if odd t: "$b$" else: "$a$" fi, 9/8[center C, point 2t+7/4 of C]);

a variation of nice Henry Menke answer with use of quotes

draw[arrow inside] (0,0) to ["$a$"] (1,0);
draw[arrow inside] (0,1) to ["$a$" '] (1,1);

Another alternative approach using Metapost. Compile this one with lualatex
.
documentclass[border=5mm]{standalone}
usepackage{luatex85}
usepackage{luamplib}
begin{document}
mplibtextextlabel{enable}
begin{mplibcode}
beginfig(1);
path S, C;
S = unitsquare shifted -(1/2, 1/2) scaled 100;
C = fullcircle scaled 84 rotated 16 shifted 140 right;
interim ahangle := 30; % slimmer arrows...
drawarrow subpath(0, 5/8) of S;
drawarrow subpath(5/8, 13/8) of S;
drawarrow subpath(4, 4-5/8) of S;
drawarrow subpath(4-5/8, 4-13/8) of S;
draw subpath(13/8, 4-13/8) of S;
label.top("$a$", point 1/2 of S);
label.top("$a$", point 5/2 of S);
label.lft("$b$", point 3/2 of S);
label.lft("$b$", point 7/2 of S);
for t=0 upto 3:
drawarrow subpath 2(t, t+1) of C;
drawdot point 2t+3/4 of C withpen pencircle scaled 3;
label(if odd t: "$b$" else: "$a$" fi, 9/8[center C, point 2t+7/4 of C]);
endfor
endfig;
end{mplibcode}
end{document}

a variation of nice Henry Menke answer with use of quotes
library:
documentclass{article}
usepackage{tikz}
usetikzlibrary{decorations.markings, quotes}
begin{document}
begin{tikzpicture}[auto=right,
arrow inside/.style = {
decoration={markings, mark=at position 0.5 with {arrow{stealth}}},
postaction={decorate},
}
]
draw[arrow inside] (0,0) to ["$a$"] (1,0);
draw[arrow inside] (0,1) to ["$a$" '] (1,1);
draw[arrow inside] (0,0) to ["$b$" '] (0,1);
draw[arrow inside] (1,0) to ["$b$"] (1,1);
end{tikzpicture}

What have you tried?

I thought about doing something with tikzpicture and explicitly stating the parametrization of each length but it seems that there ought to be a more elegant way to do it.

@zjs Just post what you have got. It will be much easier to see what you want if you post a code example.
