Is there an easy way to strip yaml blocks from markdown files, or more concretely - anything between and including the first and second occurence of `---` and `---`.

wow, can’t believe I just wrote something (jank 1000) for this last week:  
[https://github.com/Moelf/BigG.jl/blob/9f79a16266da89584018bd324198a2874c3146fb/src/BigG.jl#L79-L85](https://github.com/Moelf/BigG.jl/blob/9f79a16266da89584018bd324198a2874c3146fb/src/BigG.jl#L79-L85)

if you want the block inclusively, just remove `+1` and `-1`

now that I’m posting my inefficient code, I have to make a version where you don’t have to read the whole file:

```julia
function revise(path)    
    t = open(path)       
    lines = []               
    c = 0                
    while c<2       
        r = readline(t)
        (r == "---" && (c+=1))              
        push!(lines, r)                  
    end                           
    return join(lines, "\n")    
end  

```

Thanks. I reworked your example to keep the md and remove the YAML:

```julia
# Remove YAML block
mdlines = readlines(file)
md = join(mdlines[findall(x -> x=="---", mdlines)[2]+1:end], "\n")
write(file, md)

```

ah, didn’t realize stripe means get rid off, I thought you want to extract that block of YAML (biased based on my use case of course), in that case `readlines` should be just fine.

No worries! It did most of what I needed. I’m trying to use .jmd files from Weave.jl in Documenter.jl, and Documenter doesn’t seem to handle .jmd yet so I’m just deleting the YAML
