(#152) > > This algorithm has been described in some detail in [a recent blog > post][Expl3-Linter-11.5]. > > [Expl3-Linter-11.5]: https://witiko.github.io/Expl3-Linter-11.5/ "Static analysis of expl3 programs (11½): Chunks, edges, flow graphs, confidence, and reaching definitions" > > Flow analysis remains disabled by default, since no issues are reported from > it yet. To enable it, set the Lua option `stop_after = "flow analysis"` > either in your Lua code or your configuration file. > > After this change, you may already see preliminary flow analysis results in > explcheck's verbose output. However, unless explcheck understands your file > sufficiently well, it will typically stop before reaching the flow analysis > step and will report this in the verbose output. > > If explcheck reaches semantic analysis, you can encourage it to proceed to > flow analysis by decreasing the Lua option `min_code_coverage` towards zero. > If explcheck bails out earlier, try disabling `stop_early_when_confused` or, > ideally, improve your code quality and contribute to expltools so that it can > understand your code better. ? > > - In the syntactic analysis, fix the assignment of segment numbers to `T`- and > `F`-type arguments. (#152) > > - Add Lua options `max_reaching_definition_inner_loops` and > `max_reaching_definition_outer_loops`. (#152) > > These options help guard against the reaching definitions algorithm failing > to converge fast. > > #### Continuous integration > > This version of explcheck has made the following changes to our continuous > integration: > > - Bump actions/download-artifact from 6 to 7. (contributed by @dependabot in #153) > > - Bump actions/upload-artifact from 5 to 6. (contributed by @dependabot in #154) > > - Display processing progress in the CI. (#152) > > - Analyze package files using multiple CPUs in the CI. (#152) > > This speeds up the CI by ca 40% from ca 25 minutes to ca 15 minutes. > > ---------------------------------------------------------------------- > > The package’s Catalogue entry can be viewed at > https://ctan.org/pkg/expltools > > The package’s files themselves can be inspected at > https://mirrors.ctan.org/support/expltools/ > > ---------------------------------------------------------------------- > > Thanks for the upload. > > For the CTAN Team > Vincent Goulet > > ---------------------------------------------------------------------- > > CTAN is run entirely by volunteers and supported by TeX user groups. > Please join a user group or donate to one, see https://ctan.org/lugs
