@singularitti Also, if non-generator-like for requires do or another token, you could change this to:

Suggested change
"for",
"for(?=.*do)",

This should now only match expressions like: for ... do

Hi, I am trying to use this pattern "^\s*for" (A for with only blank characters before it) to replace "for", but it does not seem to succeed. The below generator expression

[getfield(x, :a) for x in object.b.c],

is still treated as a for loop.

for
As an example, I only want the first for be matched.

I'm not familiar with Julia. Why the for preceeded by @SoftScope shouldn't be matched? This might bring problems with the matching end for it.

Check if this token works well enough for for:

  • (?<=\\[[^\\]]*)for(?![^\\]]*\\]))

It uses negative lookahead and positive lookbehind to try and match those generators.
I don't know if it can handle nested or multiline generators.

Another option is adding [ and ] as open and close tokens for an ignore block. This is not ideal, but would avoid ugly breakage for the rest of the file

Hi @polvalente, thank you for your reply. I am not an expert in regex, so I just wrote the simplest example. Yes, indeed, that will break the highlighting.

I cannot figure out a good regex to distinguish the for loops and generator expressions. Because Julia is so flexible that it allows a lot of ways to write a for loop. The only difference between them just seems to be for loops have an end. I will list some test examples below. I hope you can figure out a working way to distinguish them. Thank you!

Below are normal for loops so should be paired with ends.

# Those should be matched.
for i = 1:10
           s += i
       end

@softscope for i in 1:10
           s += i
       end

softscope(Main, :(for i = 1:10
           s += i
       end))

for i in 1:10; println(i); end

for i in [1, 2, 3]
	println(i)
end

for i in collect(1:10)
	println(i)
end

Below are generator expressions and are not paired with ends:

# Those should not be matched.
sum(1/n^2 for n=1:1000)

 map(tuple, (1/(i+j) for i=1:2, j=1:2), [1 3; 2 4])

[(i,j) for i=1:3 for j=1:i if i+j == 4]

Oh wow. I think there is a problem with how I implemented ignore blocks. I'll refactor it in the coming weekend.

Basically, I didn't think to support nesting. As such, ((x) for) will be passed to the coloring function as for) (because the first closing paren will close the first open paren).

Luckily, I already have an idea on how to solve it (by using stacks).

I have tried this method. It seems that with the following test text:

sum(1/n^2 for n=1:1000)

map(tuple, (1/(i+j) for i=1:2, j=1:2), [1 3; 2 4])

[(i,j) for i=1:3 for j=1:i if i+j == 4]

for i = 1:10
    s += i
end

@softscope for i in 1:10
    s += i
end

softscope(Main, :(for i = 1:10
    s += i
end))

for i in 1:10; println(i); end

for i in [1, 2, 3]
println(i)
end

for i in collect(1:10)
println(i)
end

image

The map(tuple, (1/(i+j) for i=1:2, j=1:2), [1 3; 2 4]) is not working because there is one ) before the for.

This test now works:
