Symbolic Expressions As Markup.
Because all markup is terrible, especially XML/SGML and derivatives.
But mainly, for easier static markup code generation, such as with macros, code includes and such.
This may be used as a library, such as from within a server,
generating HTML (or any other supported markup) before it is served to the
client. Personally, I am currently just using the seam binary to statically
generate some personal and project websites.
Read the USAGE.md file for code examples and documentation.
- XML
- HTML
- CSS
You may clone the repo, then build and install
git clone git://git.knutsen.co/seam
cd seam
cargo build --release
cargo install --path .Or install it from crates.io
cargo install seamEither way, you'll need the Rust (nightly) compiler and along
with it, comes cargo.
You may use it by doing
seam test.sex --html > test.htmltest.sex contains your symbolic-expressions, which is used to generate
HTML, saved in test.html.
Likewise, you may read from STDIN
seam --html < example.sex > example.html
# Which is the same as
cat example.sex | seam --html > example.htmlYou may also very well use here-strings and here-docs, if your shell supports it.
seam --html <<< "(p Hello World)"
#stdout:
# <!DOCTYPE html>
# <html>
# <head></head>
# <body>
# <p>Hello World</p>
# <!-- Generated by SEAM. -->
# </body>
# </html>seam --xml <<< '(para Today is a day in (%date "%B, year %Y").)'
#stdout:
# <?xml version="1.0" encoding="UTF-8" ?>
# <para>Today is a day in November, year 2020.</para>
# <!-- Generated by SEAM. -->- Rewrite lexer to only insert whitespace before and after {
(,)} and next to string-literals. Whitespace should then be added between between symbols after macro expansion, since a macro could expand to any literal. Variadic macros should preserve whitespace in its arguments entirely (no stripping). %listmacro which expands from(p (%list a b c))to(p a b c). This is essentially an anonymous macro definition, i.e(%define L a b c), then%Lis the same as(%list a b c).%for-loop macro, iterating over%lists.%globwhich returns a list of files/directories matching a glob.%markdownrenders markdown given to it.%html,%xml,%css, etc. macros which goes into the specific rendering mode.- Add variadic and keyword macro arguments.
- Caching or checking time-stamps as to not regenerate unmodified source files.
- HTML object
style="..."object should handle s-expressions well, (e.g.(p :style (:color red :border none) Hello World)) - HTML
<style>tag should allow for normal CSS syntax if just given a string. - Allow for, and handle special
@syntax in CSS, such as@importand@media. - Add more supported formats (
JSON,JS,TOML, &c.). - Add more helpful/generic macros (e.g.
(%include ...), which already exists). - Allow for arbitrary embedding of code, that can be run by
a LISP interpreter (or any other langauge), for example. (e.g.
(%chez (+ 1 2))executes(+ 1 2)with Chez-Scheme LISP, and places the result in the source (i.e.3).
