When recursive mode is used, `current-project-root` changes during the extent of a render operation. But if parallel rendering is also used, when the main thread re-parameterizes `current-project-root`, it will have no effect on the parallel threads, because they freshly instantiate `current-project-root` (with its default value). This patch moves the parameterization inside the parallel thread by passing the `current-project-root` value as part of the job message, thereby handling it the same way as `current-poly-target`.
* Specify external renderer via module and id
* faster external render check
* Update render.rkt
* rely on default exception messages, which are informative
Pagetree promises that its nodes will be resolved relative to the directory where the pagetree lives. For path-based pagetrees, make sure this directory is set correctly.
Clarify three things:
1. You can use pagetree files with `raco pollen render`
2. `--target` doesn’t prevent other file types from being rendered
3. The generated pagetree includes more than just source files
* ci: run CI for Racket 6.6 and up
Racket 6.5 has an SSL issue that makes it unable to install packages.
That might be why it was not included in the Travis build either.
* ci: drop travis config
* start command: fix default value for port
Defaulting the port to "8080" at the `command-line' level breaks
customization via `pollen.rkt'.
* test-project-port: connect to server to verify that it's up
Removes many (not all) pdflatex errors when generating PDF docs. Some
styles had to be renamed because they get reused as LaTeX
environments/commands which can only contain letters.
