"File name does not match module name" on Mac OS
Hakyll.hs:1:1:
File name does not match module name:
Saw: `Main'
Expected: `Hakyll'
Is an error encountered on Mac OS when hakyll.hs is located on a
case-insensitive filesystem. A workaround is to rename it to something that
isn't the name of the module, for example, site.hs.
pageCompiler/Hakyll/Pandoc eats my HTML!
Sometimes, it can seem that HTML pages are stripped of some arbitrary tags, e.g.
<div>'s. The issue here is that, when using the default pageCompiler, your
page passes through Pandoc. Pandoc unfortunately strips away this information,
giving you the "wrong" HTML.
The solution is not to use pageCompiler -- it is very common to write custom
page processing compiler. The definition of pageCompiler is, put simply:
pageCompiler =
readPageCompiler >>>
addDefaultFields >>> -- Sets some things like $path$
arr applySelf >>> -- Used to fill in $var$s in the page
pageRenderPandoc -- Pass through pandoc
You can add your own version in your hakyll.hs file:
myPageCompiler =
readPageCompiler >>>
addDefaultFields >>> -- Sets some things like $path$
arr applySelf >>> -- Used to fill in $var$s in the page
And using this instead of pageCompiler should solve the issue.
Does Hakyll support syntax highlighting?
Syntax highlighting is enabled by default in Hakyll if you are using a somewhat recent version of Pandoc (1.9 and onwards). Note that you also need to include some CSS in order for this to work! This site, for example, uses the default Pandoc syntax CSS file.
When should I rebuild and when should I build?
If you execute a ./hakyll build, Hakyll will build your site incrementally.
This means it will be very fast, but it will not pick up all changes.
- In case you edited
hakyll.hs, you first want to compile it again. - It is generally recommended to do a
./hakyll rebuildbefore you deploy your site.
After rebuilding your site, all files will look as "modified" to the filesystem.
This means that when you upload your site, it will usually transfer all files --
this can generate more traffic than necessary, since it is possible that some
files were not actually modified. If you use rsync, you can counter this using
the --checksum option.
