Replace the opaque CodeBlockBody external tokenizer with grammar-parsed
codeStatement* so that keywords (show, let, set, …) and identifiers
inside #{ } code blocks receive proper Lezer nodes and are highlighted.
Key grammar changes:
- CodeBlock { "{" codeStatement* "}" } — structured, not opaque
- codeStatement uses two explicit alternatives for keyword lines:
CodeKeyword !kw callOrValueAndBody (grabs the subject eagerly)
CodeKeyword keywordBody? (bare keyword or body-only form)
The !kw cut-point gives shift prec kw > 0 over the unannotated reduce,
resolving the LALR merge ambiguity without @left/@right on kw.
- callOrValue { FuncExpr | CodeIdent | CodeString } — replaces CallExpr
{ CodeIdent !call callSuffix* }. The * quantifier annotated both
shift and reduce with !call, making them a same-prec tie that @right
could not reliably resolve in merged states. Using FuncExpr (required
callSuffixes) + bare CodeIdent makes the tie strict (call > 0 for
FuncExpr shift vs 0 for bare-ident reduce), then @right handles only
the extension-of-callSuffixes case (shift = call<<2, FuncExpr reduce
= call<<2 - 1 via @right encoding).
- KeywordExpr gets the same two-alternative structure as codeStatement
so nested show/set/let inside a code block (e.g. show sel: set text)
also parse without LALR state-merge conflicts.
- CallExpr removed; its role is split between FuncExpr (has args/chain)
and bare CodeIdent (no args). Styling updated: CodeExpr/CodeIdent
replaces CallExpr/CodeIdent for bare #ident function-style highlights.
- codeKeywordTokenizer and codeIdentTokenizer already accept keywords /
identifiers after { and ; (added in previous commit) — consistent with
the new grammar.
Parse results:
#{ show strong: link.with(url); body }
→ CodeKeyword "show", CodeIdent "strong", FuncExpr "link.with(url)",
CodeIdent "body" — all properly highlighted, no ⚠ errors.

overleaf/web
overleaf/web is the front-end web service of the open-source web-based collaborative LaTeX editor, Overleaf. It serves all the HTML pages, CSS and javascript to the client. overleaf/web also contains a lot of logic around creating and editing projects, and account management.
The rest of the Overleaf stack, along with information about contributing can be found in the overleaf/overleaf repository.
Running the app
The app runs natively using yarn and Node on the local system:
$ yarn install
$ yarn run start
Running Tests
To run all tests run:
make test
To run both unit and acceptance tests for a module run:
make test_module MODULE=saas-authentication
Unit Tests
The test suites run in Docker.
Unit tests can be run in the test_unit container defined in docker-compose.tests.yml.
The makefile contains a short cut to run these:
make test_unit
During development it is often useful to only run a subset of tests, which can be configured with arguments to the mocha CLI:
make test_unit MOCHA_GREP='AuthorizationManager'
To run only the unit tests for a single module do:
make test_unit_module MODULE=saas-authentication
Module tests can also use a MOCHA_GREP argument:
make test_unit_module MODULE=saas-authentication MOCHA_GREP=SSO
Acceptance Tests
Acceptance tests are run against a live service, which runs in the acceptance_test container defined in docker-compose.tests.yml.
To run the tests out-of-the-box, the makefile defines:
make test_acceptance
However, during development it is often useful to leave the service running for rapid iteration on the acceptance tests. This can be done with:
make test_acceptance_app_start_service
make test_acceptance_app_run # Run as many times as needed during development
make test_acceptance_app_stop_service
make test_acceptance just runs these three commands in sequence and then runs make test_acceptance_modules which performs the tests for each module in the modules directory. (Note that there is not currently an equivalent to the -start / -run x n / -stop series for modules.)
During development it is often useful to only run a subset of tests, which can be configured with arguments to the mocha CLI:
make test_acceptance_run MOCHA_GREP='AuthorizationManager'
To run only the acceptance tests for a single module do:
make test_acceptance_module MODULE=saas-authentication
Module tests can also use a MOCHA_GREP argument:
make test_acceptance_module MODULE=saas-authentication MOCHA_GREP=SSO
