Getting lmt to work

tl;dr -- lmt needs there to be either:

• markdown after the last file piece
• two newline characters

!git clone https://github.com/driusan/lmt

fatal: destination path 'lmt' already exists and is not an empty directory.

%cd lmt

/content/lmt

%%capture
!apt install golang

!go build

import os
os.environ['PATH'] = f'{os.environ["PATH"]}:/content/lmt'

%cd /content

/content

%%writefile test.go.md
# Thing

```go test.go
package main

import (
	fmt
)
```

Overwriting test.go.md

!lmt test.go.md

!cat test.go

cat: test.go: No such file or directory

%%writefile test2.go.md
# Thing

```go test2.go
package main

import (
	fmt
)
```

Overwriting test2.go.md

!lmt test2.go.md

!cat test2.go

cat: test2.go: No such file or directory

%%writefile test3.go.md
# Thing

```go test3.go
package main

import (
	fmt
)
```
# Blah

Writing test3.go.md

!lmt test3.go.md
!cat test3.go

//line test3.go.md:4
package main

import (
	fmt
)

%%writefile test4.go.md
# Thing

```go test4.go
package main

import (
	fmt
)
```

Writing test4.go.md

!lmt test4.go.md
!cat test4.go

//line test4.go.md:4
package main

import (
	fmt
)
